The Apollo Telescope Mount (ATM) was designed and developed by the Marshall Space Flight Center (MSFC) and served as the primary scientific instrument unit aboard Skylab (1973-1979). The ATM consisted of eight scientific instruments as well as a number of smaller experiments. This image is of the ATM thermal unit being tested in MSFC's building 4619. The thermal unit consisted of an active fluid-cooling system of water and methanol that was circulated to radiators on the outside of the canister. The thermal unit provided temperature stability to the ultrahigh resolution optical instruments that were part of the ATM.

The Stellar Reference Unit (SRU) on NASA's Juno spacecraft made this first-of-a-kind observation on Dec. 30, 2023, of an elongated, 40-mile-long (65-kilometer-long), curvy thermal emission feature and a shorter linear emission segment to the west of South Zal Mons. The resolution is 0.6 miles (1 kilometer) per pixel. The feature is suspected to be an active lava channel, given the similarity of its morphology to that of the two previously identified lava channels on Io. The shape of the Ionian lava channel near Hi'iaka Montes is compared to the SRU emission feature in the left panel. Juno's infrared camera, JIRAM, observed a long thermal emission "hot spot" at lower resolution (19 miles, or 30 kilometers, per pixel) in May 2023 at the same location (JIRAM infrared data is overlaid on the SRU image in the right panel, illustrating the overlap). https://photojournal.jpl.nasa.gov/catalog/PIA26523

Ahead of launch as part of NASA’s Commercial Lunar Payload Services (CLPS) initiative, Astrobotic’s Peregrine lunar lander is encapsulated in the payload fairing, or nose cone, of United Launch Alliance’s Vulcan rocket on Nov. 21, 2023, at Astrotech Space Operations Facility near the agency’s Kennedy Space Center in Florida. Launch of Astrobotic’s Peregrine Mission One will carry NASA and commercial payloads to the Moon in early 2024 to study the lunar exosphere, thermal properties, and hydrogen abundance of the lunar regolith, magnetic fields, and the radiation environment of the lunar surface.

The transport carrier containing the European Service Module for NASA’s Artemis III mission arrives at the Neil A. Armstrong Operations and Checkout Building at NASA’s Kennedy Space Center in Florida on Tuesday, Sept. 3, 2024. The European Service Module, which is assembled by Airbus in Bremen, Germany, from parts made in 10 European countries and the United States, acts as the driving force behind Orion for deep space exploration, providing essential propulsion, thermal control, and electrical power.

The SpaceX Crew Dragon spacecraft that will be used for the company’s uncrewed flight test, known as Demonstration Mission 1, arrived to Cape Canaveral Air Force Station in Florida on Tuesday, July 10, 2018. The spacecraft recently underwent thermal vacuum and acoustic testing at NASA’s Plum Brook Station in Ohio. The Demonstration Mission 1 flight test is part of NASA’s Commercial Crew Transportation Capability contract with the goal of returning human spaceflight launch capabilities to the United States.

STS088-319-031 (4-15 December 1998) --- Astronauts Jerry L. Ross (left) and James H. Newman, both mission specialists, are pictured in their thermal undergarments prior to the first extravehicular activity (EVA) for the mission. They went on to complete a total of three such spacewalks designed to help prepare the recently-connected Russian-built FGB Module (Zarya) and the United States-built Unity Module (Node 1), the first two modules for the International Space Station (ISS).

The Apollo Telescope Mount (ATM), designed and developed by the Marshall Space Flight Center, was one of four major components comprising the Skylab. The ATM housed the first marned scientific telescopes in space. In this photograph, taken at the Manned Spacecraft Center (later renamed the Johnson Space Center), an ATM prototype can be seen in a thermal vacuum chamber that tested the unit's ability to withstand the environment of space.
