In papers filed with the city of Alameda to lease a building at a former naval air station there, Astra Space described plans to develop a rocket called Astra, 12 meters tall, capable of placing 100 kilograms into low Earth orbit. That vehicle is one of dozens under development by companies and government agencies worldwide, seeking to tap into what they perceive to be the growing demand for dedicated smallsat launch services.
