Elon Musk, the founder of SpaceX, contributed $50 million for St. Jude’s Children’s Research Hospital to assist it with surpassing Inspiration4’s $200 million fundraising goal.

The tycoon tweeted out his pledge only hours after the space flight closed its three-day mission by effectively sprinkling down in the Atlantic Ocean off Florida Saturday evening.

“Count me in for $50M,” he wrote in the posting.

Very rich person tech business visionary Jared Isaacman, who purchased the flight with SpaceX and declared the mission would raise assets for St. Jude’s, gave $100 million to the reason.

With Musk’s commitment and the $60 million gave by the public, $210 million was brought up for children’s cancer research.

Hayley Arceneaux, the flight’s medical officer and a physician assistant at St. Jude’s, said Musk’s pledge “carries tears to my eyes.”

“Thank you​ ​@elonmusk​ ​for this liberal gift toward our $200 million dollar fundraising goal for​ ​@StJude!!!,” she said on Twitter.​

The Inspiration4’s mission took off from Kennedy Space Center in Florida on a SpaceX ​Falcon 9 rocket last Wednesday.

The SpaceX Crew Dragon case conveyed Isaacman, Arceneaux, a youth cancer survivor, Sian Proctor, a geologist, and Chris Sembroski, a Lockheed Martin worker.

The crew stayed in orbit for three days and arrived at an elevation of 367 miles.

The mission denoted whenever a flight originally went into orbit with an all civilian crew.
