Q&A with Josef Aschbacher, director of ESA’s Earth observation programs (members only)

A Vega rocket faltered minutes after liftoff from French Guiana at 9:53 p.m. EDT Wednesday (0153 GMT) and failed to reach orbit with a European-built reconnaissance satellite for the United Arab Emirates. The payload and launcher fell into the Atlantic Ocean, marking the first failure for the solid-fueled Vega launch vehicle.

United Launch Alliance teams loaded super-cold liquid hydrogen and liquid oxygen into an Atlas 5 rocket Friday at Cape Canaveral during a countdown dress rehearsal for a planned launch next month with the Solar Orbiter mission, a robotic spacecraft to study the origins of the solar wind and image the sun’s poles for the first time.

Rocket Lab’s Electron launcher delivered two all-weather radar Earth observation satellites into orbit for Capella Space Thursday night after liftoff from Wallops Island, Virginia, successfully completing the company’s second flight from the U.S. spaceport.
