Briefings

Cowboy Space unveiled Big Iron, a 86-meter stainless-steel launch vehicle designed to carry 15,000+ kg to sun-synchronous orbit. The rocket will serve as a megawatt-class data center, with its upper stage becoming the satellite's radiator and Ammonia propellant acting as coolant. Cowboy aims for a first flight in 2028, following successful testing of its Clydesdale engines at NASA's Stennis Space Center. The vehicle will launch up to 20,000 satellites in a future constellation, with the first laser power beaming demo scheduled for October 2026.
