1.1 Summary

The International Space Station (ISS) is “the first borderless world

“

mankind has ever had in history. The

United States of America (US), Japan, Canada, European countries and Russia are participating in this ISS

program. These partners have been collaboratively promoting the construction, assembly, and utilization of the

ISS. This type of collaboration, which utilizes the state-of-the-art technologies from many different countries

for constructing a single facility, has never been done before. The ISS, in many ways, is truly a symbol of

global cooperation and peace, as well as an important research facility to provide a major breakthrough in the

world’s space development endeavors.

The conceptual design of the space station’s drawing was initiated in 1982. The first ISS component, the

Zarya Module, was launched in 1998 overcoming numerous obstacles through the international cooperation of

the ISS partner countries. The ISS construction was once suspended due to the Space Shuttle Columbia

accident in 2003. However, from 2006, the ISS construction has resumed with the target completion year set at

2010.

This chapter describes the background and the surrounding issues related to the development of Kibo from

the perspectives of cross-border collaboration and Japan’s domestic activities.

1.2

International Space Station (ISS) Program

1.2.1 Outline

The International Space Station (ISS) is a manned research facility flying about 400 km above the earth.

While the ISS orbits the earth at a rate of 90 minutes per orbit, earth observation, astronomical observations

and scientific experiments are conducted on-board.

The primary objectives of the ISS are to provide a facility for conducting long-term experiments and

researches by using the environment unique to space, to promote science and technology by utilizing the results

from these experiments and researches, and to contribute to the betterment of mankind and a means for

commercial development.

For the assembly and construction of the ISS, the US space shuttles and Russia’s Proton and Soyuz launch

vehicles are used for transporting the ISS components, one segment after another, more than 40 launches

projected to assemble the ISS. The US, Japan, Canada, Russia and 11 of the 17 member countries of the

European Space Agency (ESA), including Italy, Denmark, Norway, Belgium, Netherlands, France, Spain,

Germany, Swedish, Switzerland and the United Kingdom (UK), are participating in this international

collaborative program, as ISS partner countries. Japan contributes to the ISS program through the

development and utilization of Kibo.

1.3

Background of Kibo Development

In June 1982, the government of Japan was requested from NASA to participate in the Space Station

Program. In response to this request, a technical study led by the National Space Development Agency of

Japan (NASDA) was initiated to establish the basic framework for Japan’s participation in the Space Station

Program. In August 1982, the Space Station Program Task Force was formed under the auspices of the Space

Development Committee. Deliberations on Japan’s participation in the Space Station Program Framework were

started.

In April 1985, the "Basic Framework for Participating in the Space Station Program" was established based

on the results from the studies conducted by the Space Development Committee's Space Station Taskforce.

Japan’s participation in the Space Station Program was then officially announced. In the "Basic Framework

for Participating in the Space Station Program", the significance of Japan’s participation in the program was

described. The following is a summary of the framework.

(1) High

Technology

Acquisition

The space station is expected to actively and extensively use advanced technologies. This will ultimately

lead to acquiring techniques for supporting manned space flight and the developing leading edge space

technologies while this large construction project in space is ongoing. The space station will also lead to the

promotion and development of advanced technologies in several fields including robotics, computers, and

communications. In addition, significant improvements in advanced technology standards are anticipated.

(2) Promotion of Science and Technology for the Next Generation, and Expansion of Space

Activity Scope

The space station has the capability to 1) extend the amount of time that humans can spend in space, 2)

accommodate many crew members, and 3) increase power supply and crew time. This capability would

enable extensive scientific observations or conducting larger experiments in space. It would also increase the

opportunity for new scientific findings and promote the development of new technologies. In addition, the

space station has the capability of being an outpost for on-orbit space activities, or could be a base station for

supporting manned explorations to the moon and other planets. These capabilities will lead to expanding the

scope of human activities in space.

(3) International

Contribution

Japan is expected to fulfill Japan’s share of international responsibility by contributing to the world’s space

development through the technologies fostered by Japan’s own independent developments or by utilizing the

space shuttles. Through collaboration and participation in the Space Station Program, the relationship

between the US and Japan can be maintained or enhanced. In addition, Japan’s technology will be enhanced

by keeping pace with the world’s space development. Specifically, Japan will be able to internationally

Kibo HANDBOOK

contribute to the advanced technology fields, including electronics, optical communication and robotics, which

are technological strengths of Japan.

(4) Promotion of Practical Application of Space Environment Utilization

Recently, experiments using the space environment, including the development of materials and the

production of medicines, are being promoted. The utilization of the space environment has received a

significant amount of attention. The Space Station Program will advance space environment utilization.

Space utilization is generally targeted for commercial activities. Expansion of commercial activities in space

is a goal for many countries, including the United States.

With the aim of achieving the above objectives, Kibo has been developed as Japan’s first manned spacecraft.

Table 1.3-1 shows the background of Kibo development.

Kibo Operation Mode

Four different operation modes are used for managing Kibo’s systems. Kibo operation mode varies

according to the Kibo’s operations and/or the upper ISS operation modes. Kibo operation modes and the

corresponding descriptions are shown in Table 3.2-1. The operation mode can be switched manually by crew

or by commands sent from the ground. Figure 3.2-1 shows the Kibo operation mode transition.

switching the Kibo operation mode from “Standard Operation Mode” to “Robotics Operation Mode” for

JEMRMS operation. The relation between Kibo operation modes and ISS operation modes are shown in

Table 3.2-3. In the event of an ISS emergency, the ISS operation modes will be switched accordingly;

however if Kibo operation mode at this point is not applicable, then Kibo operation mode will be switched to

“Standby Mode” automatically.

There are situations where Kibo operation modes are constrained depending on the status of the ISS

operation mode. For example, the ISS operation mode has to be set as “External Operation Mode” when

switching the Kibo operation mode from “Standard Operation Mode” to “Robotics Operation Mode” for

JEMRMS operation. The relation between Kibo operation modes and ISS operation modes are shown in

Table 3.2-3. In the event of an ISS emergency, the ISS operation modes will be switched accordingly;

however if Kibo operation mode at this point is not applicable, then Kibo operation mode will be switched to

“Standby Mode” automatically.

Pressurized Module (PM)

4.1.1 Brief Summary

Kibo’s Pressurized Module (PM) is a research facility

where astronauts will enter and conduct scientific experiments

or control Kibo’s systems. The air composition inside the PM

is nearly the same as that on earth. The air pressure is

maintained at one atmospheric pressure (1atm), thus providing

a comfortable working environment for the astronauts. The

temperature and humidity inside the PM are also controlled so

that the astronauts will be able to work in a shirt-sleeve

environment.

Inside the PM, the inner walls will hold racks that are composed of either JEM system or scientific research

payloads. The work space inside the PM is almost square in shape and is 2.2 m in height and width. An

internal view of the PM is shown in Figure 4.1.2-2.

The PM can hold a total of 23 racks. The racks are built into the inner four walls of the PM. Of the four

inner walls, six racks will be built into three of the walls, and five racks will be built in the remaining wall.

Of these racks, 11 racks are for JEM system, and 12 are for payloads. The racks can be attached or detached

on orbit. Figure 4.1.2-3 shows the locations of the JEM system racks. Figure 4.1.2-4 shows the locations of

the payload racks. A schematic of how to attach and/or detach the racks is shown in Figure 4.1.2-5.

The payloads racks are designed according to the standardized specifications for hardware interface power

and data interface. These racks built in accordance with the required standardized specifications are called

“International Standard Payload Rack (ISPR)”. Of the 12 payload racks inside of the PM, 11 racks are ISPRs

and one rack is for storing experiment materials.

Facility

4.3.1 Brief Summary

Kibo’s Exposed Facility (EF) is a multipurpose experiment

platform where various scientific activities, including scientific

experiments, earth observation, communication, scientific and

engineering experiments or material experiments can be

conducted by utilizing the microgravity and vacuum space

environment. The EF can be used when the EF is berthed to

the PM. The Equipment Exchange Unit (EEU) will

accommodate a maximum of 12 payloads, including the

Exposed Facility (EF) payloads, ELM-ES and the Inter-orbit

Communication System (ICS). Since the EF payloads can be

exchanged on orbit, it is expected that several different types of

scientific experiments can be conducted on the EF.

In order to support the space-exposed experiments on the EF, the EF will provide the necessary electrical

power to each payload, wi

ired temperature and will

collect experiment data.

4.3.3 System Components of EF

The EF consists of the following subsystems;

•

Electrical Power System (EPS)

•

Communication and Tracking (C&T)

•

Thermal Control System (TCS)

•

Structure

•

Mechanical System

The Electrical Power System (EPS), Communication and Tracking (C&T) and Thermal Control System

(TCS) have redundant functionality. If the primary strings of these subsystems fail, the secondary strings will

take over and maintain their system functions. The following are details of the subsystems.

(1) Electrical Power System (EPS)

The Electrical Power System (EPS) receives electrical power from the PM and distributes power to the EF

equipment, Exposed Pallet (ELM-ES), and EF payloads attached to the EF respectively.

(2) Communication and Tracking (C&T)

The Communication and Tracking (C&T) includes the Exposed Facility System Controller (ESC), which is

installed on the EF and controls the EF equipment or system devices by communicating with the JEM Control

Processor (JCP). The ESC also rela

payloads, such as experiment data,

image, temperature and pressure data.

(3) Thermal Control System (TCS)

The Thermal Control System (TCS) is composed of the following two systems. The Active Thermal

Control System (ATCS) which transfers heat generated in the equipment and payloads by circulating the

coolant, Fluorinert

, and the Passive Thermal Control System (PTCS) which maintains the temperature of the

EF system equipments or payloads through the use of thermal insulators or heaters. The TCS manages the

temperature environment for the EF system and payloads operation by protecting the EF from the extreme

space thermal environment. The heat collected by the ATCS will be transferred to the Heat Exchanger

installed on the PM structure. Coolant loops pipes have no redundancy; however other components, such as

pumps, have redundancy.

(4) Structure

The Structure of the EF is composed of box shaped units, which consist of aluminum alloy frames, panels,

and trunnions that are used to attach the EF to the space shuttle’s cargo bay.

acility Unit (EFU) and is located on the

side of the EF. The passive EEU, known as the Payload Interface Unit (PIU), is located on the EF payloads.

Electrical Power System (EPS), Communications and Tracking (C&T) or Thermal Control System (TCS) are

critical systems for operating the EF, thus these system units are designed as ORUs. In case of failure, these

units can be exchanged on orbit. There are two types of ORUs on the EF. The first type of ORU is the

Extravehicular Activity ORU (E-ORU), which is attached to the nadir side of the EF, and will be exchanged by

extravehicular activities. The second ORU type is Robot essential ORU (R-ORU) which is attached to the

zenith side, and will be exchanged by JEMRMS, Kibo’s robotic arm.

The EF Equipment Exchange Unit (EEU) is a mechanism that attaches the EF payloads to the EF. Once a

payload is attached to the EF by the EEU, the electrical power system (EPS), communication and tracking

•

Electrical Power System (EPS)

•

Communication and Tracking (C&T)

•

Thermal Control System (TCS)

•

Structure

•

Mechanical System

Details of the subsystems are as follows.

(1) Electrical Power System (EPS)

The Electrical Power System (EPS) receives power from the space shuttles during the period from launch to

docking with the ISS, and distributes the power to ELM-ES system and Exposed Facility (EF) payloads.

Power will be supplied from the EF while the ELM-ES is operated on orbit.

(2) Communication and Tracking (C&T)

The Communication and Tracking (C&T) includes the Electronic Control Unit (ECU) that is installed on the

ELM-ES. The ECU monitors the status of the ELM-ES, temperature of the EF payloads attached on the

ELM-ES, and the status of the Payload Attachment Mechanisms (PAMs) by communicating with the JEM

Control Processor (JCP) on the PM. The ECU also controls the PAMs or temperature of the attached EF

payloads.

(3) Thermal Control System (TCS)

The ELM-ES is entirely covered with thermal insulating materials in order to prevent the temperature of the

ELM-ES system from exceeding the operating temperature. In addition, to maintain the ELM-ES thermal

environment, heating devices are installed in the areas where thermal insulating material are not sufficient and

the temperature may exceed tolerable temperature ranges. In addition, heating devices are installed in the EF

system ORU and EF payloads which are attached on the ELM-ES.

(4) Structure

The ELM-ES structure is designed to bear loads imposed during the space shuttle’s launch, ascent, ISS

attitude control and maneuver. The main sections of the ELM-ES are composed of aluminum alloy panels in

a reticular pattern. A mechanism called “Trunnion” fastens the ELM-ES to the space shuttle’s cargo bay.

The ELM-ES has five Trunnions.

.5.1 Brief Summary

Japanese Experiment Module Remote Manipulator System

system intended for supporting experiments being

ace. The JEMRMS will be the third remote manipulator

robotic arm system designed for space operations that Japan

will have flown into space. The JEMRMS follows Japan’s

Manipulator Flight Demonstration (MFD)*

in August 1997

and the Engineering Test Satellite VII (ETS-VII)*

, also

known as “KIKU No.7”, in November 1997. The JEMRMS

is composed of two arms, the Main Arm (MA) and the Small

Fine Arm (SFA). The robotic control workstation, known as the JEMRMS Console, is used to operate the

JEMRMS.

Both the Main Arm (MA) and Small Fine Arm (SFA) have six joints and allow for similar movements with

the human arm. Inside the PM, the crew will control the JEMRMS, while watching images on the TV

monitor, located on the JEMRMS Console, which are taken from the cameras attached to the arm.

With these arms, the crew can conduct several tasks including exchanging EF payloads or EF system ORUs

that are located on the EF and ELM-ES. The ten-meter-long Main Arm transfers (grapple and move) large

objects, and the two-meter-long Small Fine Arm is used for precise, delicate and fine-tuned operations.

The JEMRMS will be operated for more than ten years on orbit. Thus, the JEMRMS has exchangeable or

repairable design in case of failure. These arms can be repaired by intra-vehicular or extravehicular activities.

(Repair of the Main Arm will be conducted only by extravehicular activity.)

Table 4.5.1-1 shows the specifications for the JEMRMS (Main Arm and Small Fine Arm).

Arm

(MA)

The Main Arm (MA) consists of MA Booms, MA Joints, MA Television Cameras (TV Cameras), MA

Camera Pan Tilt Unit (PTU), a light and the MA End Effector (grapple fixture) that grapples EF payloads.

There are three MA Booms, known as MA Boom 1, 2 and 3. Vision equipments (TV Cameras, PTU and

light) are attached to the MA Boom 2 and MA Boom 3. The crew will control the JEMRMS while watching

the images, which are taken with the visual equipment, on the TV monitor located on the JEMRMS Console.

The Main Arm is primarily used for exchanging EF payloads (Standard payload envelope is planned to be

1.85m x 1.0m x 0.8m and weighing less than 500kg). The EF payload is grappled and moved by the

JEMRMS Main Arm End-Effector.

(2) Small Fine Arm (SFA)

The Small Fine Arm (SFA) consists of SFA Electronics, SFA Booms, SFA Joints, end effectors called “Tool”,

and SFA TV Cameras. The SFA is used when the SFA is grappled by the MA End Effector.

The SFA is primarily used for precise, delicate and fine-tuned tasks, which include exchanging the Orbital

Replacement Units (ORU) on the EF. (ORU size is planned to be 0.62 x 0.42 x 0.41 m, and weighing 80 kg

max)

The SFA is designed with a compliance function that was validated on the Manipulator Flight Demonstration

(MFD) during the STS-85 mission. This feature allows the crew to easily operate the arm. The SFA

compliance function utilizes the Force/Torque Sensor on the arm to sense when a target is touched, after which

the attitude of the arm is automatically controlled.

S-PM and ICS-EF components.

(1) ICS Pressurized Module (ICS-PM) subsystem

The ICS Pressurized Module (ICS-PM) subsystem is comprised of seven Orbital Replacement Units (ORUs).

Equipment or devices, such as the Base Band Data Processing Unit, are included in those ORUs. These

ORUs are installed in the ICS rack and manages the ICS.

Primarily, the ICS-PM multiplexes the data of the Kibo’s system and experiment payloads for downlink from

Kibo to the ground, demultiplexes the data uplinked from the ground, and modulates the data before sending or

demodulates the data after receipt.

In addition, the ICS-PM has an automatic operation scheduling function where, commands are uplinked

from the ground in advance while the DRTS is in a communication window. The commands uplinked from the

ground are stored in the ICS-PM. Each command is executed at the scheduled time. This provides ICS

scheduled automatic operations. In addition, the ICS-PM has data recording function for later downloading to

the ground, whenever real time communication is not available.

(2) ICS Exposed Facility (ICS-EF) subsystems

The ICS Exposed Facility (ICS-EF) subsystem is comprised of several components, including Pointing

Mechanism, frequency converters, High-Power Amplifier, as well as, various sensors, including the Earth

sensor, Sun sensor and Inertial Reference Unit.

Data downlinked from Kibo to the ground are relayed to the ICS-EF by the ICS-PM. The data is passed

through the frequency converter and power amplifier, and then, sent to the DRTS. Data uplinked from the

ground will pass through the frequency converter, converted to a low frequency, and then, relayed to the

ICS-PM.

In addition, the ICS antenna can automatically track the DRTS. The ICS-EF determines the antenna’s

attitude based on data from the Earth sensor, Sun sensor and Inertial Reference Unit, while at the same time,

calculating the antenna’s directions based on the ISS and DRTS orbital positions The ICS-EF moves the

antenna using the Antenna

CS attitude, and tracks the

DRTS automatically. Further, while communicating with the DRTS, the ICS can calibrate the direction of the

DRTS by detecting any pointing error based on the high-frequency signals that the antenna receives.

5.2.1 1J/A Flight

During the 1 J/A Flight, the Experiment Logistics Module – Pressurized Section (ELM-PS) will be delivered

to the ISS. The ELM-PS will be carrying Kibo’s system racks (JEM system racks) and payload racks.

Figure 5.2.1-1 shows the expected external view of the ISS after completion of the 1J/A Flight Mission. The

planned cargo bay layout during launch of the 1J/A Flight is shown in Figure 5.2.1-2.

After the docking of the space shuttle to the ISS, the following procedures will be used to attach the ELM-PS

to the ISS. Figure 5.2.1-3 shows the procedures for attaching the ELM-PS to the ISS.

Space shuttle docks to ISS

Canadarm2 (ISS robotic arm) grapples the Orbiter Boom Sensor System (OBSS) and removes the

OBSS from the space shuttle’s cargo bay. (This will provide sufficient clearance for the safe removal

of the ELM-PS from the space shuttle’s cargo bay.) (Figure 5.2.1-3 (1))

The Shuttle Remote Manipulator System (SRMS) removes the ELM-PS from the space shuttle’s cargo

bay. (Figure 5.2.1-3 (1) to Figure 5.2.1-3 (3))

The ELM-PS is attached, by the SRMS, to the Common Berthing Mechanism (CBM) at the zenith side

of Node 2. (Figure 5.2.1-3 (4))

The CBM vestibule is pressurized. The crew connects the electrical power cables and air ducts

between the ELM-PS and Node 2.

The ELM-PS is powered up and activated. The operational status of the ELM-PS is checked.

The crew enters the ELM-PS from Node 2.

Eventually, the ELM-PS will be attached to the PM. However, since the ELM-PS will be launched before

the PM, the ELM-PS will temporarily be attached to the Node 2 until the PM is delivered to the ISS.

Note: The above procedures are based on NASA/JAXA coordination as of March 2007. The above

procedures are subject to change dependent on possible changes.

Kibo Operations Control

The International Space Station (ISS) program, which includes the construction, assembly, and utilization of

the ISS, has been promoted by the United States (US), Japan, Canada, 11 European countries that belong to the

European Space Agency (ESA), and Russia. Overall operations of the ISS are coordinated by the US. Each

International Partner is responsible for operating each country’s own ISS component including ISS

components/modules/segments, ISS payloads or equipment.

Communications between the ISS and the International Partners are conducted through the Tracking and

Data Relay Satellite (TDRS) by way of NASA Johnson Space Center (JSC) and White Sands Ground Station.

Japan will alternatively use JAXA’s Data Relay Test Satellite (DRTS), known as Kodama, for communicating

with Kibo. Russia communicates with the ISS only when direct communications with the ISS are permitted,

and uses the TDRS as a backup communication method.

6.1 Summary

400 km above the earth, construction and assembly of the International Space Station (ISS) is ongoing.

Aboard the ISS, various scientific experiments are currently or will be conducted by utilizing an environment

unique to space. The space environment is characterized by microgravity, space radiation, vast views, very

high vacuum and an abundant source of solar energy. These environmental conditions are completely different

and difficult to fully duplicate from what is available on earth. The results from these experiments are

expected to enhance the capabilities of our 21st century industry and will also be used for the betterment of

mankind. On Kibo, several types of scientific experiments that will use Kibo’s pressurized and exposed

facilities are planned. This chapter describes Kibo’s space experiment environment and the experiment

payloads planned to be used inside or outside of Kibo, and introduces Kibo’s utilization plans during Kibo’s

initial utilization phase.

6.2 Environment

6.2.1 Microgravity

Every object orbiting the earth, like the ISS, is in a state of continuous free-fall towards the center of the

earth. Under these conditions, these orbiting objects are under the influence of microgravity or near zero

gravity conditions. On-board the ISS, several factors including atmospheric drag, gravity gradient (tidal

force), crew activities, and the station’s solar array rotations may affect the ISS gravitational environment.

However, microgravity is still only about 10

-6

to 10

-4

g of that on earth, and thus can be utilized for long-term

research on-board the ISS. (Note: 1 g is a measurement expressed as an object’s nominal acceleration at

9.80665 m/s

due to gravity on Earth at sea level and known as G-force or G-load). Utilizing this

microgravity environment, several types of experiments or studies on the effects of gravity on life are under

consideration for Kibo’s future experiments.

6.2.2 Line of Sight and field of view from the ISS

The line of sight from certain sites of the ISS can be blocked by the ISS structural components, including the

pressurized modules or rotating solar arrays. The field of view or what can be seen depends on location and

the direction of the line of sight.

Since Kibo will be located at the front of the ISS (ISS’s direction of travel), a relatively wider field of view

can be seen from the Exposed Facility (EF) experiment payloads site attached to the front (ISS’s direction of

travel) of the Kibo’s Exposed Facility (EF).

The field of view from the EF experiment payload #1, that will be attached to the EF, was estimated by a

field of view analysis. Figure 6.2.2-1 shows an estimated field of view from the EF experiment payload #1.

Mission planning for an experiment, which will be conducted using an EF experiment payload on the EF and a

view is of importance, will need to factor in the results of the field of view analysis.

6.2.3 Background Atmosphere

The degree of vacuum at the ISS orbit (at an altitude of 400 km) is approximately 10

-5

Pa. Water dumps

from the ISS or water dumps from the space shuttle being docked to the ISS could affect this vacuum

environment. In addition, the atmospheric density of the environment surrounding the ISS may vary

depending on solar and geomagnetic activities.

At the altitude where the ISS orbits, a significant amount of atomic oxygen exists. The atomic oxygen is

formed from dissociated oxygen molecules exposed to ultraviolet (UV) radiation. Atomic oxygen is known to

oxidize, erode and contaminate spacecraft materials on orbit.

Excluding water dumps from the ISS, there are many contamination sources in Kibo’s surrounding

environment, including out-gassing from the ISS components (gasses emitted from organic materials) or

thruster burns by the space shuttles or other spacecrafts. When planning experiments for the EF, atmospheric

factors will need to be taken into consideration.

6-3

6. Kibo Utilization

6-4

6.2.4 Space Radiation

The environment where the ISS orbits are comprised of cosmic radiations, including a radiation belt (Van

Allen belts) consisting of particles captured by the earth's magnetic field, solar flare particles (solar protons)

generated by solar activities, and galactic cosmic rays that originates from outside the solar system. The

environment outside and inside the ISS can be affected by cosmic radiations impacted with the ISS structural

components or the atmosphere, which in turns generates secondary radiations. The cosmic radiation may

cause malfunctions with the ISS equipment, which is known as a “single event effect”. Additionally, the

cosmic radiation may adversely affect the health of the ISS crew. Therefore, observations and researches on

cosmic radiation have become increasingly important.

6.2.5 Thermal Environment

The ISS and Kibo’s thermal environments are complex and composed of direct solar exposure, sun light

reflected from the earth (albedo), infrared radiation and cosmic background radiation. The temperature

surrounding the ISS and Kibo ranges from -150

C to +120

C (degree Celsius), depending on the shaded or

un-shaded area of the ISS or Kibo. The thermal environment can also vary depending on the relative position of

the sun and the ISS orbital plane.

Before designing an EF experiment payload, as well as Kibo’s components, verification that EF experiment

payload itself is strong enough to endure the severe thermal conditions of space including interruptions or

reflections attributed to ISS’s surrounding components should be done.

6.2.6 Micrometeoroid and Space Debris

In space, micrometeoroids which are believed to originate from comets or asteroids and space debris, which

originate from artificial satellites, spacecraft components, old launch vehicles or orbit burns of solid rocket fuel,

are orbiting the earth. These orbiting micrometeoroids and space debris may possibly impact the ISS or Kibo.

Under an altitude of 2,000 km above the earth, more than 10,000 pieces of space debris, the size of 10 cm or

greater, have been confirmed. If a piece of debris that may impact the ISS is predicted or confirmed, a debris

avoidance maneuver that alters the ISS orbital altitude will be implemented. In addition, debris shields or

debris bumpers are installed around the outside surface of the PM and ELM-PS for protecting these

components’ structural bodies from possible space debris impacts. Moreover, these components are designed

not to break apart even if a hole is made in the component’s surfaces from debris impacts. The safety of the ISS

crew can be ensured by evacuating the crew to a different ISS module, and then, closing and securing the

hatches of the affected module.

6.3 Experiment

Payloads

6.3.1 Experiment Payloads for Kibo’s Pressurized Module (PM)

(1) Cell Biology Experiment Facility (CBEF)

The Cell Biology Experiment Facility (CBEF) is equipped with an incubation environment where the

temperature, humidity and carbon dioxide (CO2) concentration can be controlled. The basic phenomena of life

in space can be studied through the use of cells from animals, plants, microorganisms, etc. A centrifuge will be

used to generate an artificial gravity environment, thus experiments in both a microgravity and artificial gravity

environment can be conducted in Kibo.

The culture chamber will be set in a “canister” and installed within the CBEF. Through a utility connector

inside the CBEF, the canister can receive power, command input, sensor output, video output. These utilities

will provide support for an efficient experimental environment. In addition, by placing the canister in the

Clean Bench (CB), the ISS crew can, by using the Clean Bench’s glove box, directly handle the samples inside

the canister.

Figure 6.3.1-1 shows an overview of the CBEF. Table 6.3.1-1 shows the CBEF specifications.

The CBEF will be installed in the “SAIBO” experiment payload rack in Kibo’s Pressurized Module (PM).

The Clean Bench (CB) will also be installed in the “SAIBO” rack. The CBEF will be operated at the location

as shown in Figure 6.3.1-2.

(2) Clean Bench (CB)

The Clean Bench (CB) will provide an aseptic glove-box operating compartment called “Operation Chamber

(OC)” where germfree operations can be conducted. Life Science and biotechnological experiments can be

performed on-board Kibo through the use of the CB. The CB has a Disinfection Chamber (DC), which is

separated from the OC. This separation prevents the OC from becoming contaminated by microorganisms

while transferring samples or equipment. In addition, the OC is equipped with ultraviolet lamps for

sterilization and High Efficiency Particle Air (HEPA) Filters. These filters eliminate particles that are

suspended in the air. Consequently, germfree experiments can be conducted by the Clean Bench. The front

of the OC is comprised of transparent materials so as to provide good views of the inside of the OC. The ISS

crew will be able to conduct germfree experiments by directly monitoring the insides of the OC. In addition,

to support the experiments, a phase-contrast/fluorescent microscope and a monitor camera are installed in the

CB.

Figure 6.3.1-3 shows an overview of the CB. Table 6.3.1-2 shows the CB’s specifications.

The CB will be installed in the “SAIBO” experiment payload rack in the PM together with the CBEF, and

will be operated at the location as shown in Figure 6.3.1-2.

(3) Fluid Physics Experiment Facility (FPEF)

The Fluid Physics Experiment Facility (FPEF) is an experiment facility for conducting fluid physics

experiments at ambient temperature and in a microgravity environment. In space or in a microgravity

environment, the effects from thermal convection are lower than that on earth. Thus, Marangoni convection

(convection attributed to differences between surface tensions) is significant. The primal objective of the

FPEF is to investigate the Marangoni convection in a space environment which affects such as the

semiconductor single crystal growth experiment. The results from investigating the Marangoni convection

are expected to facilitate control of convections that are currently hampering industrial applications. The

results, by deepening our understanding of the Marangoni convection, may be applied to methodologies for

eliminating foam or bubbles in fluids.

As part of the FPEF standard functions, the FPEF has the following features for observing, measuring or

monitoring: (1) two-dimensional (2D) and three-dimensional (3D) flow field observation for observing flow

distributions, (2) surface temperature measurement, (3) velocity profile measurement using ultrasound, and (4)

surface flow velocity monitoring. Currently, the “Liquid Bridge” application is being planned for the FPEF

for investigating the Marangoni convection. In addition, several Experiment Cells are being developed to meet

several diverse experiment purposes. Figure 6.3.1-4 shows an overview of the FPEF. Table 6.3.1-3 shows the

FPEF specifications.

The FPEF will be installed in the “RYUTAI” experiment payload rack inside the PM. The FPEF will be

operated at the location as shown in Figure 6.3.1-5.

(4) Solution/Protein Crystal Growth Facility (SPCF)

The Solution/Protein Crystal Growth Facility (SPCF) is an experiment facility for conducting basic

researches related to crystal growth in various solutions or proteins in a space environment. The SPCF

consists of the Solution Crystallization Observation Facility (SCOF) and the Protein Crystallization Research

Facility (PCRF). The SCOF uses cell cartridges for growing solution crystals. In-situ observations can be

performed while the crystals are growing by controlling the temperature and pressure in the cell cartridge. A

Mach-Zehnder (MZ) Interference Microscope and a Dynamic Light Scattering unit are mounted in the SCOF

for crystal growth observation, crystal surface observation, liquid-phase temperature/concentration distribution

measurements, and/or particle size distribution measurements. The second SPCF facility, the PCRF, is a

facility for growing large and high-quality protein crystals for ground structural analyses.

The SCOF and PCRF can be operated separately as independent facilities. The overviews of the SCOF and

PCRF are shown in Figure 6.3.1-6 and Figure 6.3.1-7, respectively. The specifications for the SCOF and

PCRF are shown in Table 6.3.1-4 and Table 6.3.1-5, respectively.

The SPCF will be installed in the “RYUTAI Rack” in the PM together with the FPEF, and will be operated at

(5) Gradient Heating Furnace (GHF)

The Gradient Heating Furnace (GHF) is a multipurpose electrical furnace for conducting experiments related

to vapor deposition and crystal growth of semiconductor materials. The GHF is comprised of a furnace, a

Control Equipment, and a Sample Cartridge Automatic Exchange Mechanism (SCAM) with a controller.

Samples will be heated or cooled in the Furnace Section. The Control Equipment will receive commands

from the ground to control the experiments while relaying data to the data communication system of Kibo.

The SCAM can accommodate up to 15 samples and can automatically exchange the samples. There are three

heating units in the Furnace Section. Each heating unit can independently be controlled or maneuvered. Thus,

different temperature profiles can be set for conducting various experiments. When running the experiments

in the GHF, fusion and unidirectional solidification of the samples can be conducted. The GHF overview is

shown in Figure 6.3.1-8. The GHF specifications are shown in Table 6.3.1-6.

The GHF will be installed in the “KOBAIRO” experiment payload rack, with power or coolant water being

supplied from the PM. Data can be sent to or received from the ground.

(2) Superconducting Submillimeter-Wave Limb-Emission Sounder (SMILES)

The Superconducting Submillimeter-Wave Limb-Emission Sounder (SMILES) will observe submillimeter

wavelengths that are emitted from trace gases in the stratosphere. These observations will be conducted by

pointing the SMILES antenna (Submillimeter Antenna (ANT)) at the upper reaches of the atmosphere. The

SMILES can determine the amount of trace gases that exist in the ozone layer. The SMILES measures the

distribution and changes in the trace gases in the stratosphere, globally, with a high degree of accuracy.

The Submillimeter-wave Receiver installed in SMILES is comprised of a superconductive sensor and

amplifiers (low noise). The SMILES uses a highly sensitive superconductive sensor and a 4-Kelvin

mechanical cooler that are world leading edge components.

An overview of the SMILES is shown in Figure 6.3.2-2. The specifications of SMILES sensors and

measuring instruments are shown in Table 6.3.2-2.

(3) Space Environment Data Acquisition equipment-Attached Payload (SEDA-AP)

The Space Environment Data Acquisition equipment-Attached Payload (SEDA-AP) will measure the space

environment (neutrons, plasma, heavy ions, high-energy light particles, atomic oxygen, and cosmic dust) at the

ISS orbit. Using the SEDA-AP, the space environmental effects on materials and electronic devices will be

investigated.

A number of sensors and equipment are mounted in the SEDA-AP, including the Neutron Monitor (NEM)

and the Plasma Monitor (PLAM). Space environment data obtained by the SEDA-AP will be applied to the

development of future spacecraft designs. The data will also be utilized for ISS operations and related

scientific researches, and space weather forecast (prediction of solar activity trends).

The SEDA-AP will conduct measurement and monitoring by extending a mast, on which the Neutron

Monitor (NEM) - Sensor and the Plasma Monitor (PLAM) are attached. The mast extends to over 1 m from

the SEDA-AP structural body. The experiments using the SEDA-AP sensors and electronic devices will

measure, monitor, and collect data, simultaneously, for three consecutive years.

An overview of the SEDA-AP is shown in Figure 6.3.2-3. The specifications for the SEDA-AP sensors and

6.4.3 Experiment Themes

The scientific experiment themes, which will be conducted in Kibo’s Pressurized Module (PM), were

domestically solicited in 1992. The preliminary selections of the domestic experiments were conducted in

August 1993. Life Science and microgravity-science experiment themes that will be conducted in Kibo’s

Pressurized Module (PM), were also solicited internationally. Preparations of the selected experiment themes

from domestic and international applications have been in progress as part of the collaborative activities

between the themes’ principal investigators and Japan Aerospace Exploration Agency (JAXA). The

preparations include preparations of the experiment plans (protocols), refinement of the specifications for the

payloads, evaluations on the experiment operational tasks, and pilot studies on experiments using the space

shuttles. Through these activities, the required techniques and methods for conducting experiments utilizing

Kibo facilities have been accumulated.

Table 6.4.3-1 shows the experiment themes of Kibo (Material Science and Life Science) that will utilize

Kibo’s Pressurized Module (PM) during the First Utilization Phase. Table 6.4.3-2 shows the experiment

themes that will utilize Kibo’s Exposed Facility (EF) or other ISS facilities (non-Kibo facilities).

6.4.4 Utilization Plan

For the First Phase Utilization, which will continue for three years from the beginning of the Kibo operations

until 2010, the detailed operations plans have been deliberated at the ISS/Kibo Utilization Promotion

Committee, which is an external advisory committee to JAXA. The allocation of the utilization resources per

study field or the experiment payloads that will be loaded on Kibo, or the experiment themes that are targeted

for international coordination in 2008, were arranged in 2005.

For international coordination, the allocation of the ISS utilization resources and optimization of the ISS

overall resources are currently being evaluated based on the ISS overall logistics plan and the ISS overall

operations plan.

7.1 Summary

The H-II Transfer Vehicle (HTV), designed and being built in Japan, is an unmanned cargo transfer

spacecraft that will deliver supplies to the International Space Station (ISS).

The HTV will be launched from the Tanegashima Space Center in Japan aboard an H-IIB Launch Vehicle

(currently under development). When the HTV approaches close proximity to the ISS, the Space Station

Remote Manipulator System (SSRMS), also known as "Canadarm2," will grapple the HTV and berth it to the

ISS. The HTV will deliver up to 6,000 kg of supplies, including food, clothing and several types of

experiment payloads to the ISS. After the supplies are unloaded, the HTV will then be loaded with waste

materials, including used payloads or used clothing. Afterward, the HTV will undock and depart from the ISS,

and will de-orbit and reenter the atmosphere. While the HTV is berthed to the ISS, the ISS crew members

will be able to enter and remove supplies from the HTV Pressurized Logistics Carrier (PLC).

Figure 7.1-1 shows an image of the HTV on-orbit.

Figure 7.1-1 Image of HTV during Flight

The HTV will be utilized for delivering supplies to the ISS as with the Russian Progress cargo spacecraft, the

U.S. space shuttle, and the Automated Transfer Vehicle (ATV) developed and built by the European Space

Agency (ESA),. The HTV can carry both pressurized (for inside use) and un-pressurized (for outside use)

cargo, and this is a unique special feature of the HTV.

The launch of the HTV "Technical Demonstration Vehicle" (initial flight vehicle) is scheduled during Japan’s

fiscal year 2009 (JFY 2009). Thereafter, one or two HTVs per year are planned for launch.

Following the launch phase, the HTV will be inserted into an elliptical orbit with an altitude of 200 km

(perigee) x 300 km (apogee) and a inclination of 51.6 degree.

After separating from the H-IIB launch vehicle, 1) the HTV will automatically activate the HTV subsystems,

2) maintain its attitude,3) perform a self-check on the HTV’s components, and 4) initiate communications with

the HTV Control Center (HTV-CC) at Tsukuba Space Center (TKSC).

7.2.2 Rendezvous

After separating from the H-IIB launch vehicle, the HTV will approach the ISS in the following sequence as

described below. Figure 7.2.2-1 shows the HTV Rendezvous Flight profile that depicts how the HTV will

approach the ISS, by boosting (adjusting) the HTV’s orbital altitude.

After separating from the H-IIB launch vehicle, the HTV will automatically activate HTV’s

communication system and initiate communications with NASA's Tracking and Data Relay Satellite

(TDRS).

The HTV status will be monitored from the ground. Next, the HTV will then start orbital flight

towards the ISS.

After three days of orbital flight, the HTV will reach close proximity to the ISS.

The HTV will reach the proximity "Communication Zone" (23 km from the ISS), at which point the

HTV can directly communicate with the ISS

The HTV will establish communications with the Proximity Communication System (PROX).

While communicating with PROX, the HTV will approach the ISS, guided by GPS signals (Relative

GPS Navigation), until the HTV reaches the “Approach Initiation (AI) Point, 7 km behind the ISS .

At this point, the HTV will maintain this distance from the ISS.

oach the ISS from the nadir (bottom) side of the ISS (from the direction of Earth).

The HTV will then be grappled by the Canadarm2 and berthed to the ISS.

Figure 7.2.3-1 HTV Proximity Operations

The HTV's approach to the ISS during the Proximity Operation Phase is as follows.

The HTV will move from the Approach Initiation (AI) Point to a point 500 meters below the ISS, as

guided by Relative GPS Navigation

Using a laser radar called “Rendezvous Sensor (RVS)”, the HTV will approach closer to the ISS. Laser

reflectors are installed on Kibo (This is called “RVS Navigation”)

The HTV will slowly and gradually approach the ISS. The HTV will hold its approach twice, when

reaching the following points: HTV will stop 300 m below the ISS (hold point), and will stop 30 m

below the ISS (Parking Point).

Eventually, the HTV will approach a proximity area called “Berthing Point”. This point is set 10 m

below the ISS, and is in a predetermined area which is called ”Berthing Box”. Next, while at the

Berthing Point, the HTV will maintain its distance from the ISS

The HTV’s approach speed during the RVS Navigation phase is 1 to 10 meters per minute. During the

Once the HTV Control Center (HTV-CC) at the TKSC confirms that the HTV’s approach and distance from

the ISS is within the Berthing Box, the ISS crew will inhibit the HTV thrusters (Figure 7.2.3-2 above). Next,

the Canadarm2 will grapple the HTV and berth the HTV to the CBM located at the nadir side (earth side) of the

Node 2. The HTV will the

7.2.4 Operations while berthed to the ISS

Once the HTV is berthed to the ISS, the lights in the PLC will be powered up and the air pressure in the PLC

will be adjusted by ISS crew or the HTV-CC for ingress preparation. After completing these preparatory

tasks, both the HTV and ISS hatches will be opened. The temperature inside of the PLC will be maintained at

15.6

C (degrees Celsius) before the ISS crew enters the PLC. This is a preemptive measure to hinder the

possible formation of dew upon the crew entering the PLC. While the HTV is berthed to the ISS, power will be

supplied from the ISS to the HTV.

After the hatches between the ISS and HTV opened, the ISS crew will start transferring the supplies (ISPRs,

drinking water, clothes, etc.) from the PLC to the ISS. After the supplies are transferred, the HTV will be

loaded with waste from the ISS.

In addition, in order to unload the supplies from the Exposed Pallet (EP), the EP will be removed from the

HTV’s Unpressurized Logistics Carrier (UPLC) and will be attached to the ISS Mobile Base System (MBS) or

Kibo's Exposed Facility (EF). An example of the EP Type I transfer procedure is as follows.

The Canadarm2 will grapple the EP, and remove the EP from the UPLC (Figure 7.2.4-1)

The EP will be handed from the Canadarm2 to the JEMRMS, Kibo’s robotic arm (Figure 7.2.4-2 (2))

The EP will be attached to Kibo’s Exposed Facility (EF) by the JEMRMS (Figure 7.2.4-2 (4))
