Bryson DeChambeau was visibly in awe during the sixth test flight of Elon Musk’s SpaceX Starship rocket on Tuesday.

The test was another step toward Musk’s plan to use the rocket system to send humans to Mars. NASA also plans to land humans on the moon at some point this decade under the Artemis program.

On Wednesday, DeChambeau posted a video of his reaction as the rocket launched from the surface. In the clip, the two-time US Open champion looked like he was witnessing the greatest thing in the history of men.

‘I’ve never been so inspired #spacex,’ he captioned

‘Come on, baby,’ DeChambeau chants, clapping, at the beginning of the clip. The camera then turns to the rocket taking flight.

While the rocket got farther from the ground, the camera turned back to a close-up shot of DeChambeau gazing into the sky, his jaw moving in the opposite direction of the shuttle.

As DeChambeau’s jaw dropped, marveling at the sight of the launch, US President-elect Donald Trump could be seen a few feet behind him, dawning a Make America Great Again hat.

The pair’s relationship goes a long way as they frequently hit the golf course together. Furthermore, DeChambeau was not only present at Trump’s Election Day party, but the soon-to-be 47th president called him onto the stage during his victory speech.

DeChambeau’s awe towards the feat is no surprise given his self-professed love for physics. His fascination led to the moniker ‘The Mad Scientist.’

The golfer’s fandom aside, Starship, the most powerful rocket assembled, successfully landed in the Indian Ocean. The mission appeared to succeed despite the booster rocket failing a previously planned tower catch.
