In one of the most dramatic, high-risk space flights to date, SpaceX launched a gargantuan Super Heavy-Starship rocket on an unpiloted test flight Sunday and then used giant “mechazilla” robot arms on the pad gantry to pluck the returning first stage out of the sky in an unprecedented feat of engineering.
United Launch Alliance fired off a next-generation Vulcan rocket Friday in the second of two “certification” test flights needed before the new launcher can be used to carry high-priority national security payloads for the U.S. Space Force and the National Reconnaissance Office. One of two solid-propellant strap-on boosters provided by Northrop Grumman suffered an anomaly of some sort. ULA CEO Tory Bruno said it will be investigated.
Billionaire Jared Isaacman and SpaceX crew trainer Sarah Gillis prepared to open the forward hatch of their Polaris Dawn spacecraft early Thursday to take turns floating outside in the first non-government spacewalk in the history of space exploration. Depressurizing the spacecraft will begin around 2:23 a.m. EDT (0623 UTC) and a scaffold-like “Skywalker” assembly extending just above the hatch will be used for stability.
Despite NASA’s concerns about earlier thruster problems and multiple helium leaks in the ship’s propulsion pressurization system, the Starliner had no trouble undocking and moving away from the station at 6:04 p.m. EDT and executing a critical 59-second deorbit braking maneuver at 11:17 p.m. to drop out of orbit.
