CAPE CANAVERAL, Fla. (WNCN) — A four-man space crew consisting of an astronaut and three others who spent $55 million apiece for their seat splashed down off the Florida coast on Monday, marking a few firsts in space history.

The flight, which took off on April 8, was the first time NASA opened its space hatches to tourists. One of the billionaires aboard, Israeli investor Eytan Stibbe, also made history as the second Israeli person to ever fly into space.

The experience was especially personal for Stibbe since he served as a fighter pilot under Ilan Ramon, Israel’s first astronaut. Ilan was one of seven crew members who died in the 2003 Space Shuttle Columbia disaster.

The full crew included Stibbe and fellow billionaires Mark Pathy, a Canadian private equity CEO and Larry Connor, an American real estate tycoon. Serving as their chauffeur to space was Michael Lopez-Alegria, an Axiom vice president who flew to space four times in his time as a NASA astronaut.

Their stay at the International Space Station was originally slated to last a little over a week, but dicey weather kept them in orbit nearly twice as long as intended.

After their 17-day journey, AP reports that the hosting aerospace company, SpaceX is already itching to get geared up for its next mission — launching three NASA astronauts and one Italian to the space station as soon as Wednesday.

“The pace is blazingly fast by NASA standards. “It’s absolutely exciting,” NASA flight director Zeb Scoville told the Associated Press.

This next 4-person crew will be replacing the three Americans and a German who have been aboard the ISS since November and will head back to Earth in their own SpaceX capsule.
