Commercial Crew Partner Boeing Tests Starliner Spacecraft Engineers from NASA’s Langley Research Center and Boeing dropped a full-scale test article of the company’s CST-100 Starliner into Langley’s 20-foot-deep Hydro Impact Basin. Although the spacecraft is designed to land on land, Boeing is testing the Starliner’s systems in water to ensure astronaut safety in the unlikely event of an emergency. via NASA http://ift.tt/218F5cG

Sea Ice and Cloud Streets in the Sea of Okhotsk The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument on NASA’s Aqua satellite captured this image of cloud streets and sea ice in the Sea of Okhotsk on Feb. 8, 2016. Cloud streets are long parallel bands of cumulus clouds that form when cold air blows over warmer waters and a warmer air layer rests over the top of both. via NASA http://ift.tt/1osc2Tu

Feb. 9, 1995, Bernard Harris and Michael Foale Ready For a Spacewalk STS-63 astronauts Bernard A. Harris, Jr., payload commander (right), and C. Michael Foale, mission specialist (left), are ready to exit space shuttle Discovery’s airlock for a spacewalk on Feb. 9, 1995. On this extravehicular activity (EVA), which lasted 4 hours and 38 minutes, Bernard Harris became the first African-American to walk in space. via NASA http://ift.tt/20TmLnI
