SpaceX launched a group of astronauts for NASA early Wednesday morning, with Elon Musk’s company now having sent 26 people to orbit in less than two years.

Yes, that’s the same Elon Musk who’s been making news this week for his bid to buy Twitter.

The mission launched from the Kennedy Space Center in Florida at 3:52 a.m. ET.

SpaceX’s capsule, named Freedom, is carrying four astronauts to the International Space Station where they will spend the next six months conducting scientific experiments.

They are scheduled to dock with the ISS 16 hours after launch, around 8:15 p.m. ET.
