A full-scale BE-4 engine developed by Blue Origin, the space company founded by Amazon.com’s Jeff Bezos, is installed on a test stand in West Texas for a series of hotfire tests that United Launch Alliance will closely examine before settling on the reusable methane-fueled engine for its new-generation Vulcan rocket.

Construction crews at Cape Canaveral’s Complex 40 launch pad are busily repairing and upgrading the facility after a SpaceX Falcon 9 rocket exploded there last year, with the pad’s return to service scheduled before the end of the summer, clearing the way for final preparations for the triple-core Falcon Heavy’s maiden flight late this year.

On its second test flight Tuesday, Astra’s privately-developed small satellite launcher ran out of fuel seconds before reaching the velocity needed to enter orbit but exceeded the company’s expectations with an otherwise-successful climb into space from Kodiak Island, Alaska.
