Q&A with Mark Sirangelo, leader of Sierra Nevada Space Systems

Five days after launching from Japan, an HTV supply ship arrived Monday at the International Space Station. Capture of the HTV with the station’s robotic arm occurred at 8:13 a.m. EDT (1213 GMT). It’s the last cargo mission to the space station before the arrival of two NASA astronauts on the first crewed U.S. flight to the orbiting research facility since 2011.

SpaceX is targeting April 8 for the launch of its first resupply run to the International Space Station in nearly a year, a mission that the company hopes will mark the start of a rapid-fire launch manifest full of payloads waiting to fly.

NASA has selected six companies to work on designs for deep space habitat modules that could be used by astronauts living and working near the moon as technology is developed for eventual flights to Mars, the agency announced Tuesday.
