SpaceX’s newest Starship prototype was briefly placed atop of its massive booster for the first time on Friday (Aug. 6), setting a new record for the world’s tallest rocket ahead of a planned orbital test flight this year.

Engineers performed the stacking test at the SpaceX Starbase facility in South Texas, near the village of Boca Chica, in view of livestreams from NASA Spaceflight and SpaceX has not commented on the stacking procedure yet on Twitter, although founder Elon Musk sent an update suggesting the company actually wanted to complete the stacking Thursday (Aug. 5), a few hours after Starship completed its rollout to the launch pad, but winds were too high.
