Building a rocket is hard. AST SpaceMobile thinks it's "simple."An Ars Technica article by Eric Berger covers satellite operator AST SpaceMobile's plan, laid out by founder Abel Avellan at a Thursday event, to build the Blacklift rocket — fueled by $1.3 billion committed to Firefly Aerospace engines and tailored to lift five Bluebird satellites at a time, launching twice monthly from Wallops by 2028. Berger is skeptical: he calls the 2028 timeline preposterous, judges Avellan underestimates rocket building, and expects billions more will be needed, even while deeming the company's business plan sensible.
