Q&A with Giulio Ranzo, CEO of Avio (members only)

SpaceX is gearing up for the first full-up test-firing Thursday of all 33 engines on the booster for the company’s Starship mega-rocket in Texas, a critical milestone on the path to launching the giant vehicle on its first orbital test flight, which could happen as soon as March if this week’s test goes well.

A United Launch Alliance Delta 4 rocket climbed into orbit Friday from Vandenberg Air Force Base in California with a top secret spy satellite, adding a new set of eyes in the sky for the U.S. government’s intelligence community and nudging part of the Delta 4 family closer to retirement.

Rocket Lab’s first mission since a failed launch in early July took off at 11:05 p.m. EDT Sunday (0305 GMT Monday) from New Zealand. The small satellite launcher carried into orbit a commercial radar remote sensing spacecraft for Capella Space.
