iss070e049644 (Dec. 30, 2023) --- A set of the International Space Station's main solar arrays, slightly obscuring the smaller roll-out solar arrays, and the Kibo laboratory module with its exposed facility, an external research platform that hosts external experiments, are pictured 261 miles above the Pacific Ocean.

NASA and Boeing workers move solar arrays for the International Space Station to flight support equipment in the high bay of the Space Station Processing Facility at NASA’s Kennedy Space Center in Florida on April 2, 2021. The 63- by- 20-foot solar arrays will launch to the International Space Station later this year. They are the first two of six new solar arrays that in total will produce more than 120 kilowatts of electricity from the Sun’s energy, enough to power more than 40 average U.S. homes. Combined with the eight original, larger arrays, this advanced hardware will provide 215 kilowatts of energy, a 20 to 30 percent increase in power, helping maximize the space station’s capabilities for years to come. The arrays will produce electricity to sustain the station’s systems and equipment, plus augment the electricity available to continue a wide variety of public and private experiments and research in the microgravity environment of low-Earth orbit.

At far right, is a portion of the Kibo laboratory module with its exposed facility that houses space station hardware and external research experiments.

This cutaway illustration shows the characteristics and basic elements of the Skylab Orbiter Workshop (OWS). The OWS was divided into two major compartments. The lower level provided crew accommodations for sleeping, food preparation and consumption, hygiene, waste processing and disposal, and performance of certain experiments. The upper level consisted of a large work area and housed water storage tanks, a food freezer, storage vaults for film, scientific airlocks, mobility and stability experiment equipment, and other experimental equipment. The compartment below the crew quarters was a container for liquid and solid waste and trash accumulated throughout the mission. A solar array, consisting of two wings covered on one side with solar cells, was mounted outside the workshop to generate electrical power to augment the power generated by another solar array mounted on the solar observatory. Thrusters were provided at one end of the workshop for short-term control of the attitude of the space station.

Arrays of lights at left focus on solar array panels at right during illumination testing. The solar array is part of the 2001 Mars Odyssey Orbiter. Scheduled for launch April 7, 2001, the orbiter contains three science instruments: THEMIS, the Gamma Ray Spectrometer (GRS), and the Mars Radiation Environment Experiment (MARIE). THEMIS will map the mineralogy and morphology of the Martian surface using a high-resolution camera and a thermal infrared imaging spectrometer. The GRS will achieve global mapping of the elemental composition of the surface and determine the abundance of hydrogen in the shallow subsurface. The MARIE will characterize aspects of the near-space radiation environment with regards to the radiation-related risk to human explorers

VANDENBERG AFB, CALIF. - In the NASA spacecraft processing facility on North Vandenberg Air Force Base, the Gravity Probe B spacecraft is seen with all four solar array panels installed. Installing each array is a 3-day process and includes a functional deployment test. The Gravity Probe B mission is a relativity experiment developed by NASA’s Marshall Space Flight Center, Stanford University and Lockheed Martin. The spacecraft will test two extraordinary predictions of Albert Einstein’s general theory of relativity that he advanced in 1916: the geodetic effect (how space and time are warped by the presence of the Earth) and frame dragging (how Earth’s rotation drags space and time around with it). Gravity Probe B consists of four sophisticated gyroscopes that will provide an almost perfect space-time reference system. The mission will look in a precision manner for tiny changes in the direction of spin.

NASA and Boeing workers lift solar arrays into flight support equipment on April 2, 2021, in the Space Station Processing Facility at NASA’s Kennedy Space Center in Florida. The 63- by- 20-foot solar arrays will launch to the International Space Station later this year. They are the first two of six new solar arrays that in total will produce more than 120 kilowatts of electricity from the Sun’s energy, enough to power more than 40 average U.S. homes. Combined with the eight original, larger arrays, this advanced hardware will provide 215 kilowatts of energy, a 20 to 30 percent increase in power, helping maximize the space station’s capabilities for years to come. The arrays will produce electricity to sustain the station’s systems and equipment, plus augment the electricity available to continue a wide variety of public and private experiments and research in the microgravity environment of low-Earth orbit. Most of the station systems, including its batteries, scientific equipment racks, and communications equipment have been upgraded since humans began a continuous presence on the orbiting laboratory in November 2000. For more than two decades, astronauts have lived and worked on this unique orbiting lab, supporting scientific research that has led to numerous discoveries that benefit people on Earth and prepare for future Artemis missions to the Moon and beyond.
