With 14 electric motors turning propellers and all of them integrated into a uniquely-designed wing, NASA will test new propulsion technology using an experimental airplane now designated the X-57 and nicknamed “Maxwell.” This concept image illustrates NASA’s X-57 plane in flight. via NASA http://ift.tt/1sJCEBk

Orbital ATK’s Cygnus cargo craft is released from the International Space Station in this June 14, 2016, photograph by ESA astronaut Tim Peake. Once Cygnus reached a safe distance, ground controllers at NASA’s Glenn Research Center initiated the sequence for an experiment design to better understand how fire spreads in a microgravity environment. via NASA http://ift.tt/1PtN3WF

The American flag flies at half staff at NASA’s Kennedy Space Center in Florida, with the iconic Vehicle Assembly Building in the background. On Sunday, June 12, President Barack Obama ordered U.S. flags flown at half staff “as a mark of respect for the victims of the act of hatred and terror” at the Pulse nightclub in Orlando. via NASA http://ift.tt/1UMp3SN

The drizzle of stars scattered across this image forms a galaxy known as UGC 4879. UGC 4879 is an irregular dwarf galaxy — as the name suggests, galaxies of this type are a little smaller and messier than their cosmic cousins, lacking the majestic swirl of a spiral or the coherence of an elliptical. via NASA http://ift.tt/1UHgF73

This stunning Earth image taken by the Expedition 47 crew on May 31, 2016, from the International Space Station looks from northwestern China on the bottom into eastern Kazakhstan. The large lake in Kazakhstan with golden sun glint is the crescent-shaped Lake Balkhash, the second largest lake in Central Asia. via NASA http://ift.tt/1UiwouL

A view of the Neutron star Interior Composition Explorer (NICER) X-ray Timing Instrument without its protective blanketing shows a collection of 56 close-packed sunshades. NICER, an upcoming NASA astrophysics mission, will uncover the physics governing the ultra-dense interiors of neutron stars. via NASA http://ift.tt/1XEqZ4a

Sand dunes cover much of this terrain, which has large boulders lying on flat areas between the dunes. It is late winter in the southern hemisphere of Mars, and these dunes are just getting enough sunlight to start defrosting their seasonal cover of carbon dioxide. Spots form where pressurized carbon dioxide gas escapes to the surface. via NASA http://ift.tt/1VKpWxN
