KENNEDY SPACE CENTER, FLA. - The Commercial ITA Biomedical Experiments payload retrieved from debris of Columbia is being dismantled at KSC. Inside are several experiments carried on mission STS-107 that will be removed and transferred to alternate containers. One experiment, the Growth of Bacterial Biofilm on Surfaces during Spaceflight (GOBBSS), was a Planetary Society-sponsored astrobiology experiment developed by the Israeli Aerospace Medical Institute and the Johnson Space Center Astrobiology Center, with joint participation of an Israeli and a Palestinian student. The recovery team includes Eran Schenker of the Israeli Aerospace Medical Institute; David Warmflash of JSC, John Cassanto of ITA, and Louis Friedman, executive director of the Planetary Society. The GOBBSS material will be sent to JSC where the science team will analyze the samples, studying the effects of spaceflight on bacterial growth.

The Mars 2020 Perseverance rover's astrobiology mission will search for signs of ancient microbial life. It will also characterize the planet's climate and geology, collect samples for future return to Earth and pave the way for human exploration of the Red Planet. The mission is part of a larger program that includes missions to the Moon as a way to prepare for human exploration of the Red Planet. Charged with returning astronauts to the Moon by 2024, NASA will establish a sustained human presence on and around the Moon by 2028 through NASA's Artemis lunar exploration plans. https://photojournal.jpl.nasa.gov/catalog/PIA23920

Technicians test and extend one of the two “wings” comprising the solar arrays for NASA’s Europa Clipper spacecraft on Friday, Aug. 23, 2024, at the Payload Hazardous Servicing Facility at the agency’s Kennedy Space Center in Florida. Each array measures about 46.5 feet (14.2 meters) long and about 13.5 feet (4.1 meters) high. The spacecraft needs the massive solar arrays to power to Jupiter’s icy moon Europa to help scientists better understand the astrobiological potential for habitable worlds beyond our planet.
