SpaceX’s Starship rocket exploded minutes after launching its first test flight from the launch pad in Boca Chica, Texas, on Thursday, crashing into the Gulf of Mexico.

The rocket, powered by 33 Raptor engines, tumbled and came apart about four minutes after the launch. Starship had no people or satellites on board.

“Obviously this does not appear to be a normal situation,” SpaceX’s aerospace engineer John Insprucker said during the live broadcast of the launch as the rocket appeared to be spinning in the air.

The company, headed by Elon Musk, planned to send the 400-foot rocket on an attempted trip around the globe from the southern tip of Texas to eventually crash in the Pacific ocean near Hawaii. Despite the rocket’s explosion, the launch pad did survive.

After the launch, Musk said on Twitter that the company “learned a lot for next test launch in a few months.” It was the company’s second launch attempt after canceling one on Monday due to a frozen booster valve.

NASA administrator Bill Nelson congratulated the Starship’s team in a tweet, saying “Every great achievement throughout history has demanded some level of calculated risk, because with great risk comes great reward. Looking forward to all that SpaceX learns, to the next flight test—and beyond.”

When asked if it’s time for lawmakers to push for more commercial spaceflight regulation, House Aviation Subcommittee Chair Garret Graves (R-La.) said he doesn’t want to do “anything that impedes the progress of innovation for commercial space.”

“But obviously, you got that balance with safety. And so we’re gonna continue working with NTSB,” Graves said.
