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

The Russian Progress MS-16 cargo freighter rolled out to its launch pad Friday at the Baikonur Cosmodrome in Kazakhstan, its final stop before blastoff Sunday night with more than 5,000 pounds of fuel, food, and water for the International Space Station.

Russian ground crews are readying a robotic Progress cargo freighter for launch Thursday on an expedited trek to the International Space Station that should take less than three-and-a-half hours from liftoff to docking, cutting in half the normal transit time.

Japanese space officials have rescheduled the launch of an H-2B rocket and a space station-bound HTV supply ship for Saturday after halting a countdown last week due to a propulsion system problem and bypassing a launch opportunity Friday because of a poor weather forecast.
