In March, for example, company founder and CEO Elon Musk tweeted that SpaceX was targeting July for that landmark trial, which will require both elements of the reusable Starship system — the 165-foot-tall upper-stage spaceship, called (somewhat confusingly) Starship, and the huge first-stage booster known as Super Heavy. .
Super Heavy was not involved in the 6.2-mile-high flight; that May 5 jaunt employed just a prototype Starship upper stage, one outfitted with three of SpaceX's next-generation Raptor engines.Construction of the Super Heavy that will be involved in that flight is apparently well underway!"Stacking Super Heavy aft section," Musk wrote. .Stacking Super Heavy Aft Section pic.twitter.com/itydacQ4hMJune 15, 2021!SpaceX has not announced a specific target date for the orbital test, but early July may well be off the table at this point.
