Q&A with Greg Wyler, founder and chairman of OneWeb (members only)

The next launch of a Soyuz spacecraft carrying three space station fliers has been delayed indefinitely after testing at the Baikonur Cosmodrome in Kazakhstan revealed an unspecified technical problem, the Russian space agency announced Saturday.

On its first nighttime launch, Rocket Lab’s Electron booster climbed into orbit Sunday from New Zealand with a trio of small U.S. military payloads, demonstrating the privately-developed rocket’s ability to help meet the Air Force’s growing demand for smallsat launches.

The European Space Agency’s Rosetta mission will end Sept. 30 with a dicey descent to the core of comet 67P/Churyumov-Gerasimenko, a risky, but potentially rewarding finale punctuated by commands to automatically safe the probe’s rocket thrusters and turn off its radio transmitter.
