2020 International Space Station Configuration
This photograph shows the internal configuration of Skylab's Multiple Docking Adapter (MDA), including callouts for its various internal experiments and facilities. Designed and manufactured by the Marshall Space Flight Center, the MDA housed a number of experiment control and stowage units and provided a docking port for the Apollo Command Module.
Back dropped by the blackness of space and Earth's horizon is the International Space Station (ISS) as seen from Space Shuttle Discovery as the two spacecraft begin their relative separation. The latest configuration of the ISS includes the Italian-built U.S. Node 2, named Harmony, and the P6 truss segment installed over 11 days of cooperative work onboard the shuttle and station by the STS-120 and Expedition 16 crews. Undocking of the two spacecraft occurred at 4:32 a.m. (CST) on Nov. 5, 2007.

Eight days of construction resumed on the International Space Station (ISS), as STS-117 astronauts and mission specialists and the Expedition 15 crew completed installation of the second and third starboard truss segments (S3 and S4). Back dropped by our colorful Earth, its newly expanded configuration is revealed as pilot Lee Archambault conducts a fly around upon departure from the station on June 19, 2007.

Back dropped by the colorful Earth, the International Space Station (ISS) boasts its newest configuration upon the departure of Space Shuttle Endeavor and STS-118 mission. Days earlier, construction resumed on the ISS as STS-118 mission specialists and the Expedition 15 crew completed installation of the Starboard 5 (S-5) truss segment, removed a faulty Control Moment Gyroscope (CMG-3), installed a new CMG into the Z1 truss, relocated the S-band Antenna Sub-Assembly from the Port 6 (P6) to Port 1 (P1) truss, installed a new transponder on P1, retrieved the P6 transponder, and delivered roughly 5,000 pounds of supplies.

Six iROSA solar arrays in the planned configuration will augment the power drawn from the existing arrays on the International Space Station. Power channels shown are 1A, 2B, 3A, 3B, 4A, and 4B.
Photographed from the Space Shuttle Discovery upon its separation from the orbital outpost, the International Space Station (ISS) is shown sporting its new additions. A fly-around gave the crew a look at their handiwork, a new P5 spacer truss segment and a fully retracted P6 solar array wing. Earlier, the STS-116 and Expedition 14 crews concluded eight days of cooperative work onboard the shuttle and station where they accomplished the installation of the newest piece of the station and completely rewired the power grid over the course of four space walks. The station is currently the size of a typical three-bedroom house, with a surface area large enough to cover four basketball courts. The image reflects the latest configuration of the ISS as of December 19, 2006.
This view of the International Space Station, back dropped against the blackness of space and Earth, was taken shortly after the Space Shuttle Atlantis undocked from the orbital outpost at 7:50 a.m. CDT during the STS-115 mission. The unlinking completed after six days, two hours and two minutes of joint operations of the installation of the P3/P4 truss. The new 17 ton truss included batteries, electronics, a giant rotating joint, and sported a second pair of 240-foot solar wings. The new solar arrays will eventually double the onboard power of the Station when their electrical systems are brought online during the next shuttle flight, STS-116.

Named for the Greek god associated with Mars, the NASA developed Ares launch vehicles will return humans to the moon and later take them to Mars and other destinations. This is an illustration of the Ares I with call outs. Ares I is an inline, two-stage rocket configuration topped by the Orion crew vehicle and its launch abort system. In addition to the primary mission of carrying crews of four to six astronauts to Earth orbit, Ares I may also use its 25-ton payload capacity to deliver resources and supplies to the International Space Station, or to "park" payloads in orbit for retrieval by other spacecraft bound for the moon or other destinations. Ares I employs a single five-segment solid rocket booster, a derivative of the space shuttle solid rocket booster, for the first stage. A liquid oxygen/liquid hydrogen J-2X engine derived from the J-2 engine used on the Apollo second stage will power the Ares I second stage. The Ares I can lift more than 55,000 pounds to low Earth orbit. Ares I is subject to configuration changes before it is actually launched.

ISS034-E-039162 (1 Feb. 2013) --- Robonaut 2, the first humanoid robot in space, is pictured in this image photographed by an Expedition 34 crew member in the International Space Station’s Destiny laboratory. R2 was powered up so ground controllers could run it through a series of tests and configuration checks after a recent software upgrade.
S117-E-08032 (19 June 2007) --- Backdropped by a blue and white Earth, the International Space Station moves away from the Space Shuttle Atlantis. Earlier the STS-117 and Expedition 15 crews concluded about eight days of cooperative work onboard the shuttle and station. Undocking of the two spacecraft occurred at 9:42 a.m. (CDT) on June 19, 2007. Astronaut Lee Archambault, STS-117 pilot, was at the controls for the departure and fly-around, which gave Atlantis' crew a look at the station's new expanded configuration.

Introducing disorder to a crystalline system in a controlled way can form glass. Advanced Colloids Experiment-Temperature-4 (ACE-T-4) examines the transition of an ordered crystal to a disordered glass to determine how increasing disorder affects structural and dynamic properties

Hague and Williams are scheduled to exit the orbital outpost on Jan. 16 for a spacewalk to service astrophysics gear including the NICER X-ray telescope and the Alpha Magnetic Spectrometer.
S122-E-010922 (18 Feb. 2008) --- Astronaut Rex Walheim (right), STS-122 mission specialist, uses a handheld laser ranging device -- designed to measure the range between two spacecraft -- through one of the overhead windows on the aft flight deck of Space Shuttle Atlantis after undocking from the International Space Station. Astronaut Daniel Tani, mission specialist, uses a still camera to photograph the station in its new configuration.
This artist's concept depicts the Space Station Freedom as it would look orbiting the Earth; illustrated by Marshall Space Flight Center artist, Tom Buzbee. Scheduled to be completed in late 1999, this smaller configuration of the Space Station features a horizontal truss structure that supported U.S., European, and Japanese Laboratory Modules; the U.S. Habitation Module; and three sets of solar arrays. The Space Station Freedom was an international, permanently marned, orbiting base to be assembled in orbit by a series of Space Shuttle missions that were to begin in the mid-1990's.
This September 1972 photograph shows the internal configuration of Skylab's Multiple Docking Adapter (MDA) flight article as it appeared during the Crew Compartment and Function Review at the Martin-Marietta Corporation's Space Center facility in Denver, Colorado. Designed and manufactured by the Marshall Space Flight Center, the MDA housed a number of experiment control and stowage units and provided a docking port for the Apollo Command Module.

ISS034-E-031599 (18 Jan. 2013) --- Robonaut 2 is featured in this close-up image in the International Space Station?s Destiny laboratory. NASA astronaut Kevin Ford (visible in the reflections of R2?s helmet visor), Expedition 34 commander, powered up R2 so ground controllers could verify the humanoid robot?s configuration for upcoming activities.
iss060e033086 (8/9/2019) --- A view of European Space Agency (ESA) astronaut Luca Parmitano during the installation of the MultiScale Boiling Experiment Container (EC) in the Fluid Science Laboratory FSL) in the Columbus Module aboard the International Space Station (ISS). Multiscale Boiling investigates the fundamental basics of boiling heat transfer phenomena on a heater surface in a pool boiling configuration. Data from this investigation is used for the validation of theoretical models and numerical codes.
