Joint Airlock (Quest)

The Quest airlock supports Extravehicular Activity (EVA). Quest is composed of two cylindrical chambers. The larger chamber, known as the Equipment Lock, provides an area for storing and maintaining EVA equipment, and for conducting EVA preparations. The smaller chamber, known as the Crew Lock, can be depressurized to allow astronauts to exit the module. To reduce the amount of atmosphere lost during each EVA depressurization, a special pump is used to extract as much atmosphere as possible from the Crew Lock prior to venting the remaining atmosphere.

Storage boxes, mounted on the exterior of the Crew Lock, provide storage space for EVA tools used during spacewalks.

High-pressure atmospheric gas tanks are attached to the Equipment Lock exterior. These tanks can be swapped out with new tanks as needed.

Mini Research Module-1 (MRM-1)

The Russian built Mini Research Module-1 (MRM-1), provided the station with additional storage space, as well as additional clearance for Soyuz docking approaches. The MLM is berthed at the Nadir (Earth facing) port of the Zarya (FGB) module.

MRM-1 was launched with Russian and American supplies loaded inside.

Four trunnions, mounted two per side on outriggers, supported the module in the Shuttles payload bay during launch. Grapple fixtures on the module allowed the Shuttle's Canadarm Remote Manipulator System to remove it from the payload bay. The module was passed to the stations arm, Canadarm 2, for final installation.

Several components, attached to the MRM-1 exterior, will be later installed on the Multi-purpose Laboratory Module (MLM). These items included a scientific airlock, a radiator, a work platform, and a spare elbow joint for the European Robotic Arm (ERA). The MLM, scheduled for launch on a Proton rocket in late 2011, will dock at the Nadir port of the Zvezda service module.

Soyuz

Originally part of the Soviet Moon landing program, Soyuz has evolved into one of the world's most reliable crew transport spacecraft.

The value of Soyuz goes far beyond simply carrying crew to and from space. Soyuz, capable of spending six months docked to a station, can serve as a lifeboat, allowing a space station to be evacuated at any time if conditions require it. Progress supply ships, based on Soyuz technology, can supply orbiting stations with fuel, water, food, spare parts, and other critical items.

Without Soyuz and Progress, continuous crewing of orbital outposts would not be possible.

The Soyuz spacecraft is comprised of three main modules.

Orbital Module

The orbital module provides living and working space while on orbit. Docking equipment and rendezvous antennas, mounted on the top of the module, allows docking with orbiting space stations.

Descent module

The descent module contains the crew launch and entry couches, spacecraft controls and parachutes. A heat-shield protects the module during re-entry. The spacecraft has several retro rockets, designed to fire moments before touchdown, to help reduce landing impact forces.

The descent module is 2.2 meters in diameter and is the only component of the Soyuz spacecraft to return to Earth.

Service Module

The service module contains the spacecrafts main engines, attitude control system, and parts of the life support system. Radiators and antennas are mounted on the exterior. Solar panels, included on most Soyuz models, are mounted on the service module.

Soyuz-TM

Introduced in the mid-1980's, Soyuz-TM would become the primary crew transport vehicle for the Mir space station. Later missions would fly to the International Space Station.

Soyuz-TM replaced the Igla rendezvous system, used on previous Soyuz and Progress spacecraft, with the more capable Kurs system. With an ability to remain docked to a space station for six months, the Soyuz-TM was ideal for supporting long duration missions.

Soyuz-TM 1, an unmanned test flight, occurred in May 1986. The first manned mission, Soyuz-TM-2, was launched to the Mir space station in February 1987. The last mission, Soyuz-TM 34, was launched in April 2002.

Soyuz-TMA

Very similar to the Soyuz TM, the TMA model incorporates several changes to better accommodate NASA astronauts.

The first Soyuz-TMA was launched to the International Space Station in October 2002.

Space Shuttle

Set to retire in 2011, the American space shuttle has been the primary launch vehicle for ISS construction. In addition to its large cargo capacity, the shuttle was able to support space walks during early construction missions.

Multi-Purpose Logistics Module (MPLM)

The Multi-Purpose Logistics Module (MPLM) was developed to transport supplies to the ISS. Built by the Italian Space Agency, the MPLMs were designed to carry up to 16 ISS payload racks.

The MPLM could be carried to orbit in the Space Shuttle payload bay. Once the shuttle docked with the ISS, the MPLM would be removed from the payload bay and temporally berthed at one of the large CBM units.

Astronauts aboard the station would open the hatch and unload the MPLM. Even larger components, such as ISS racks could be moved this way. (Some of these components, such as ISS racks, are too large to pass through the APAS-95 docking system used by the Space Shuttle.)

Once unloaded, astronauts could fill the module with components for return to Earth. Experimental results, equipment needing repair, and trash could be returned this way. After the hatch is closed, the MPLM would be un-berthed from the station, and returned to the Shuttles payload bay. After returning to Earth, the MPLM would be unloaded, cleaned, and refurbished for use on another mission.

Three MPLMs were constructed by the Italian Space Agency.

MPLM 1 (Leonardo)
MPLM 2 (Raffaello)
MPLM 3 (Donatello)

Progress Supply Ship

Limited duration space stations, such as Skylab and several of the early Salyut stations, were launched with all the supplies needed for their planned missions. Stations designed for longer occupation often can not be launched with all supplies on board. Things such as food, water, fuel, spare parts and other items are needed to maintain the station. While crewed spacecraft, such as Soyuz, can carry a limited amount of cargo in addition to crew, it is not nearly enough to support ongoing operations.

The Soviets developed Progress, based on flight proven Soyuz-Ferry technology, as an unmanned supply ship. Not needing to include a crew, several major changes could be made. The descent module was removed completely. In its place was a newly developed tanker module. Fuel stored in tanks, within the tanker module, could be transferred to the space stations fuel tanks. This was accomplished via special propellant line connections incorporated into the docking equipment.

The orbital module was re-configured to allow transport of pressurized cargo. After docking, space station crew members could open the hatch and unload cargo from the orbital module.

While attached to a station, engines on the Progress could be used to adjust the orbit of the entire complex.

At the end of their mission, Progress spacecraft would be filled with trash, undocked from the station, and de-orbited over remote areas of the Pacific Ocean.

Early Progress spacecraft, based on the Soyuz Ferry, were battery powered and included the Igla automatic rendezvous and docking system. Progress 1, launched in January 1978, delivered food and supplies to the Salyut 6 space station. While docked, fuel transfers were successfully made between the Progress tanker module and the stations fuel tanks. Between 1978 and 1990, over forty Progress freighters were launched. Missions were flown to the Salyut 6, Salyut 7, and Mir space stations.

Progress-M, first flown in 1989, included several significant upgrades. The addition of solar panels extended the time Progress could operate independently. The Igla rendezvous system was replaced with the newer Kurs system.

A small return capsule is included on some flights. Carried in the orbital module, the return capsule could be deployed after the Progress undocks from the station.

Progress M flew dozens of successful missions to the Mir space station and the International Space Station. Improved versions continue to service the ISS.

Automated Transfer Vehicle (ATV)

Designed and operated by the European Space Agency (ESA), the ATV can deliver supplies and fuel to the ISS. The transport measures approximately 10 meters in length and 4.5 meters in diameter. Four deployable solar arrays generate electrical power. Each ATV is launched on an Ariane 5 rocket from Kourou, French Guiana. The first ATV was launched in 2008.

Using an automated system, ATV transports dock to the aft docking port of the Russian Zvezda service module. Once docked, station personnel can unload supplies from the ATV's pressurized compartment.

The transport carries a large amount of maneuvering fuel. While docked, the ATV uses its thrusters to re-boost the entire ISS as needed. The ATV carries extra fuel that can be transferred to fuel tanks on the ISS as needed.

ATV can spend several months docked to the station. Near the end of its mission, the ATV, filled with trash, undocks, maneuvers away from the station, and de-orbits over unpopulated areas of the Pacific Ocean.

H-II Transfer Vehicle (HTV)

The H-II Transfer Vehicle (HTV) was developed by the Japan Aerospace Exploration Agency (JAXA). Each HTV is launched on an H-IIB rocket. The first HTV mission occurred in 2009.

The HTV measures approximately 10 meters by 4.4 meters and can transport a payload of around 6 tons, including both internal and external cargo. Internal cargo is housed in a pressurized volume designed to hold up to eight International Standard Payload Racks (ISPRs). An unpressurized section allows external cargo to be transported. A removable pallet, supporting external cargo, can be extracted from the side of the HTV using Canadarm 2. The pallet can be temporally attached to the ISS, allowing external cargo to be unloaded as needed.

HTV spacecraft don't directly dock with the space station, as is done with Shuttle, Soyuz, Progress, and ATV, instead, the HTV will approach the station and station keep within reach of Canadarm 2. Astronauts on the station use the arm to grapple the HTV and manually move it to a berthing location. Depending on operational requirements, the transport will be berthed to either the nadir (earth-facing) or zenith port on the Node-2 (Harmony) module. Because the HTV attaches to a berthing port, rather than the smaller docking ports, larger payloads can be transferred to the station.

The HTV can spend several months at the ISS. Its mission complete, the vehicle, filled with trash, maneuvers away from the ISS and de-orbits over unpopulated areas.

SpaceX Dragon Capsule

Developed by SpaceX in partnership with NASA's Commercial Orbital Transportation Services (COTS) program, the Dragon capsule is capable of carrying both pressurized and unpressurized cargo to the International Space Station. At the end of each mission, the spacecraft can return pressurized cargo back to Earth.

With the successful completion in May 2012 of the COTS 2+ demo flight, SpaceX was ready to start regular resupply flights to the International Space Station. Two or three Commercial Resupply Services (CRS) missions will be flown by SpaceX each year. Each mission will use a Dragon capsule launched on a Falcon 9 rocket.

The first flight of the Dragon capsule, launched on a Falcon 9 rocket in December 2010, became the first privately developed spacecraft to return safely to Earth from orbit. In May 2012, the second Dragon flight became the first commercial vehicle to berth with the International Space Station.

SpaceX developed both the Falcon 9 rocket and the Dragon spacecraft. They are working toward developing rapidly reusable versions of each. A crewed version of the Dragon, capable of transporting up to seven astronauts, is in development. The Falcon Heavy rocket, also in development, will have over twice the lifting power of the largest rockets currently in use.
