NASA to Attach, Test First Expandable Habitat on International Space Station

NASA to Attach, Test First Expandable Habitat on International Space Station: The first human-rated expandable structure that may help inform the design of deep space habitats is set to be installed to the International Space Station Saturday, April 16. NASA Television coverage of the installation will begin at 5:30 a.m. EDT.

The Great Divide

The Great Divide: It's difficult to get a sense of scale when viewing Saturn's rings, but the Cassini Division (seen here between the bright B ring and dimmer A ring) is almost as wide as the planet Mercury.

Computer-Simulated Image of a Supermassive Black Hole

Computer-Simulated Image of a Supermassive Black Hole: Astronomers have uncovered a near-record breaking supermassive black hole in an unlikely place: in the center of a galaxy in a sparsely populated area of the universe. The observations, made by NASA’s Hubble Space Telescope and the Gemini Telescope in Hawaii, may indicate that these monster objects may be more common than once thought.

Hubble, Chandra, Jansky VLA Telescopes Collaborate on Galaxy Cluster

Hubble, Chandra, Jansky VLA Telescopes Collaborate on Galaxy Cluster: In October 2013 Hubble kicked off the Frontier Fields program, targeting six massive galaxy clusters, enormous collections of hundreds or even thousands of galaxies. MACS J0717, shown here, is one of the most complex galaxy clusters known, the result of four galaxy clusters colliding.

March 16, 1966: Gemini's First Docking of Two Spacecraft in Earth Orbit

March 16, 1966: Gemini's First Docking of Two Spacecraft in Earth Orbit: On March 16, 1966, command pilot Neil Armstrong and pilot David Scott successfully docked their Gemini VIII spacecraft with the Agena target vehicle, the first-ever linking of two spacecraft together in Earth orbit. This crucial spaceflight technology milestone would prove vital to the success of future moon landing missions.
