Hubble Seeks Clusters in ‘Lost Galaxy’

This NASA/ESA Hubble Space Telescope image features the spiral galaxy NGC 4535, which is situated about 50 million light-years away in the constellation Virgo (the Maiden). Through a small telescope, this galaxy appears extremely faint, giving it the nickname ‘Lost Galaxy’. With a mirror spanning nearly eight feet (2.4 meters) across and its location above Earth’s light-obscuring […]

Hazardous Material Summary Tables (HMSTs)

Hazardous Materials Summary Tables (HMSTs) are a compilation of the chemical, biological, and flammability hazards of materials on a given flight or mission. HMSTs are required by Safety for all Programs, including but not limited to ISS, Commercial Crew Program (CCP), Multi Purpose Crew Vehicle (MPCV), and Gateway. Johnson Space Center (JSC) toxicologists evaluate the […]

Toxicology Analysis of Spacecraft Air

Toxicology and Environmental Chemistry (TEC) monitors airborne contaminants in both spacecraft air and water. In-flight monitors are employed to provide real-time insight into the environmental conditions on ISS. Archival samples are collected and returned to Earth for full characterization of ISS air and water. Real-time in-flight air analytical instruments include the Air Quality Monitors (AQM), […]

NASA Tests Drones in Death Valley, Preps for Martian Sands and Skies

Next-generation drone flight software is just one of 25 technologies for the Red Planet that the space agency funded for development this year. When NASA engineers want to test a concept for exploring the Red Planet, they have to find ways to create Mars-like conditions here on Earth. Then they test, tinker, and repeat.  That’s […]
