Excerpt:

Astra was incorporated in 2016 and is based out of Alameda, California.

A lease agreement filed with the city of Alameda states that Astra Space — a relatively secretive outfit that lists itself as "Stealth Space" in public job postings — "designs, tests, manufactures and operates" launch equipment for uses including "global communications, Earth observation, precision weather monitoring, navigation and surveillance capabilities."

The company operates out of a 17,000-square-foot (1,579-square-meter) facility formerly occupied by the U.S. Navy.
