Photos: Delta 4 powers from launch pad on military mission

Flying without astronauts on a demonstration flight in Earth orbit, a test model of a next-generation Chinese crew capsule lifted off Tuesday on top of a heavy-lift Long March 5B rocket, the same launcher configuration that will loft segments of China’s planned space station.

A commercial Cygnus cargo freighter packed with 3.8 tons of medical and pharmaceutical experiments, technology demonstration hardware, CubeSats and crew provisions rode an Antares rocket into orbit from Virginia’s Eastern Shore on Wednesday afternoon on the first leg of a day-and-a-half journey to the International Space Station.

Investigators probing the sudden failure of the Boeing-built Intelsat 29e geostationary relay station in April have concluded an electrostatic discharge, aggravated by a harness flaw on the spacecraft, or a micrometeoroid strike prematurely ended the satellite’s mission, resulting in a $382 million hit to Intelsat’s quarterly financial report.
