Astronaut Scott Carpenter walks to the launch site to begin the Mercury-Atlas 7 (MA-7) mission on May 24, 1962. Carpenter’s Aurora 7 capsule lifted off aboard an Atlas rocket from Cape Canaveral, Florida, at 7:45 a.m. EST, May 24. Carpenter was the fourth American in space and second American to orbit Earth. via NASA http://ift.tt/2qQ7tq9

This illustration depicts NASA’s Mars 2020 rover on the surface of Mars. The mission, targeted for launch in July/August 2020, takes the next step by not only seeking signs of habitable conditions on Mars in the ancient past, but also searching for signs of past microbial life itself. via NASA http://ift.tt/2q7Qktb

A pair of CubeSats, with the Earth’s limb in the background, moments after being ejected from a small satellite deployer outside of the International Space Station’s Kibo laboratory module on Wednesday, May 16, 2017. Over a dozen CubeSats were ejected into Earth orbit this week to study Earth and space phenomena for the next one to two years. via NASA http://ift.tt/2qBi60p

A view of Earth from 36,000 nautical miles away as photographed from the Apollo 10 spacecraft during its trans-lunar journey toward the moon. While the Yucatan Peninsula is obscured by clouds, nearly all of Mexico north of the Isthmus of Tehuantepec can be clearly delineated. via NASA http://ift.tt/2rv852x

A fjord in southern Greenland, as seen during Operation IceBridge’s last flight of the 2017 Arctic campaign, on May 12, 2017. This final full science flight, ICESat-2 South, was designed along the ground tracks of NASA’s upcoming ICESat-2, to fill in a gap in altimetry coverage of central southern Greenland. via NASA http://ift.tt/2qRUipN

The towering primary mirror of NASA’s James Webb Space Telescope stands inside a cleanroom at NASA’s Johnson Space Center in Houston, where it will undergo its last cryogenic test before it is launched into space in 2018. In preparation for testing, the “wings” of the mirror (which consist of the three segments on each side) were spread open. via NASA http://ift.tt/2qNH25o

Nearly 50 student teams from middle and high schools, colleges and universities in 22 states demonstrated advanced rocketry and engineering skills in NASA’s 2017 Student Launch challenge. Teams spent eight months building and testing rockets designed to fly to an altitude of one mile, deploy an automated parachute system, and safely land for reuse. via NASA http://ift.tt/2pGdcek
