Eytan Stibbe and three other astronauts entered the ISS as part of the world's first fully private mission to the station.

The investment in Ramon.Space was led by top investors including Grove Ventures, one of Israel's most important firms.

Israeli astronaut Eytan Stibbe is expected to take off next year on a research mission logging 200 hours at the International Space Station.

In February, six Israeli astronauts will head to the Desert Mars Analog Ramon Station in Mizpe Ramon for a taste of the Red Planet life.
