Teams from Johnson Space Center, Exploration Ground Systems, and Jacobs TOSC conduct final inspections of Moonikin “Campos” on Nov. 9, 2021, inside the Space Station Processing Facility at NASA’s Kennedy Space Center in Florida. Moonikin “Campos” will be installed into the Orion crew module. Technicians checked connectivity and performed fit checks on his flight suit to ensure he is ready for flight aboard the Artemis flight test. Artemis I will be an uncrewed test flight of the Orion spacecraft and Space Launch System rocket as an integrated system ahead of crewed flights to the Moon. Under Artemis, NASA aims to land the first woman and first person of color on the Moon and establish sustainable lunar exploration.

Joe Leblanc, Orion payload and cargo manager with Lockheed Martin, secures Commander Moonikin Campos, a sensored stand-in for humans from NASA’s Artemis I mission, inside its transport crate in the Space Station Processing Facility at Kennedy Space Center in Florida on Jan. 10, 2023, for its trip back to NASA’s Johnson Space Center in Houston. Moonikin Campos was secured inside the Orion spacecraft for the mission beyond the Moon and back to Earth. Artemis I Orion launched atop the Space Launch System (SLS) rocket from Kennedy’s Launch Complex 39B on Nov. 16, 2022, at 1:47 a.m. EST for a 25-day trip beyond the Moon and back. During the flight, Orion flew farther than any human-rated spacecraft has ever flown, paving the way for human deep space exploration and demonstrating NASA’s commitment and capability to extend human presence to the Moon and beyond. The primary goal of Artemis I was to thoroughly test the SLS and Orion spacecraft’s integrated systems before crewed missions. Under Artemis, NASA aims to land the first woman and first person of color on the Moon and establish sustainable lunar exploration.

NASA DC-8 Ground Support Technicians Mark Corlew and Mike Lakowski perform routine maintenance on the aircraft at Carlos Ibanez del Campo International Airport in Punta Arenas, Chile. AirSAR 2004 is a three-week expedition by an international team of scientists that is using an all-weather imaging tool, called the Airborne Synthetic Aperture Radar (AirSAR) which is located onboard NASA's DC-8 airborne laboratory. Scientists from many parts of the world including NASA's Jet Propulsion Laboratory are combining ground research done in several areas in Central and South America with NASA's AirSAR technology to improve and expand on the quality of research they are able to conduct. In South America and Antarctica, AirSAR will collect imagery and data to help determine the contribution of Southern Hemisphere glaciers to sea level rise due to climate change. In Patagonia, researchers found this contribution had more than doubled from 1995 to 2000, compared to the previous 25 years. AirSAR data will make it possible to determine whether that trend is decreasing, continuing or accelerating. AirSAR will also provide reliable information on ice shelf thickness to measure the contribution of the glaciers to sea level.

ISS008-E-14686 (7 February 2004) --- This image featuring southern Spain was photographed by an Expedition 8 crewmember on the International Space Station (ISS). Over the past 50 years, the small coastal plain (campo), some 30 kilometers southwest of the city of Almeria, has been intensively developed for agriculture. The area has a dry mild, Mediterranean climate and is further sheltered on the north by the Sierra de Gador. Note the dense, bright pattern of thousands of greenhouses extending from the shoreline right up to the base of the mountains and even into some of the smaller valleys. Saltpan operations can also be seen in the long coastal lagoons.

VANDENBERG AIR FORCE BASE, Calif. -- The Aquarius/SAC-D spacecraft is in the Spaceport Systems International payload processing facility at Vandenberg Air Force Base in California. Earlier, a U.S. Air Force C-17 transport plane delivered the spacecraft from Campos, Brazil. Following final tests, the spacecraft will be integrated to a United Launch Alliance Delta II rocket in preparation for the targeted June launch to low Earth orbit. Aquarius, the NASA-built primary instrument on the SAC-D spacecraft, will map global changes in salinity at the ocean's surface. Salinity is a key measurement for understanding how changes in rainfall, evaporation and the melting of freezing of ice influence ocean circulation and are linked to variations in Earth's climate. The three-year mission will provide new insights into how variations in ocean surface salinity relate to these fundamental climate processes. Photo credit: VAFB/30th Space Wing

Following final tests, the spacecraft will be integrated to a United Launch Alliance Delta II rocket in preparation for the targeted June launch to low Earth orbit. Aquarius, the NASA-built primary instrument on the SAC-D spacecraft, will map global changes in salinity at the ocean's surface. Salinity is a key measurement for understanding how changes in rainfall, evaporation and the melting of freezing of ice influence ocean circulation and are linked to variations in Earth's climate. The three-year mission will provide new insights into how variations in ocean surface salinity relate to these fundamental climate processes. Photo credit: VAFB/30th Space Wing

Armstrong Operations and Checkout Building after NASA astronauts Zena Cardman, Mike Fincke, JAXA (Japan Aerospace Exploration Agency) astronaut Kimiya Yui, and Roscosmos cosmonaut Oleg Platonov, departed for Launch Complex 39A to board the SpaceX Dragon spacecraft for the Crew-11 mission launch, before it was scrubbed due to weather concerns, Thursday, July 31, 2025, at NASA’s Kennedy Space Center in Florida. NASA’s SpaceX Crew-11 mission is the eleventh crew rotation mission of the SpaceX Crew Dragon spacecraft and Falcon 9 rocket to the International Space Station as part of the agency’s Commercial Crew Program. Cardman, Fincke, Yui, and Platonov launched at 11:43 a.m. EDT, Friday, August 1, from Launch Complex 39A at the NASA's Kennedy Space Center. Photo Credit: (NASA/Aubrey Gemignani)
