COWBOY SPACE'S BIG IRON ROCKET TURNS ITS UPPER STAGE INTO AN ORBITING MEGAWATT-CLASS DATA CENTER

Summary from the TLDR Hardware newsletter

Big Iron is an 86 m stainless-steel, road-transportable rocket that can carry 15,000+ kg to sun-synchronous orbit on nine 300,000 lbf methalox ‘Clydesdale' engines. The upper stage can stay in orbit as a data center with five racks of Vera Rubin GPUs, with the rocket skin doubling as the radiator and ammonia propellant as coolant. Its first flight is targeted for 2028, with up to 20,000 satellites planned pending FCC approval.
