SpaceX hopes to pick up the pace with Super Heavy-Starship test flights amid concern the rocket may not be ready in time for a planned 2027 moon landing.

SpaceX crews are preparing for the 10th flight test of its Starship spacecraft and Super Heavy rocket. The launch is currently set for 7:30 p.m. on Tuesday from SpaceX’s Starbase launch facility in Texas.

In space, Starship will attempt to deploy mock Starlink satellites and reignite an engine along its suborbital path around the globe. Atmospheric reentry over the Indian Ocean will test its exterior steering flaps and an array of experimental heat shield tiles as the ship blazes through intense friction and heat.
