SOUTH PADRE ISLAND, Texas — Elon Musk’s SpaceX is again attempting to launch of its towering Starship rocket to space after scrubbing an attempt earlier this week.

SpaceX made a first go at getting this launch off the ground on Monday, but a pressure valve in the Super Heavy booster apparently froze. The company’s teams worked to resolve a number of unidentified issues to make a second attempt possible on Thursday.

The Starship orbital launch, out of a private facility in Texas along the Gulf Coast, represents the culmination of years of regulatory work and technological tests. SpaceX leadership has repeatedly stressed the experimental nature of the launch. The company had hoped to conduct the first orbital Starship launch as early as summer 2021, but faced delays in development and in winning FAA approval, which came late Friday.

Starship is designed to carry cargo and people beyond Earth and is critical to NASA’s plan to return astronauts to the moon. Two years ago, SpaceX won a nearly $3 billion contract from NASA to use Starship as a crewed lunar lander. That would see Starship be used for as part of NASA’s Artemis moon program, delivering astronauts to the lunar surface from the agency’s SLS rocket and Orion capsule.
