Elon Musk’s SpaceX rocket has successfully launched at the second attempt after the first launch was abandoned on Wednesday.

The craft is carrying astronauts Hurley and Behnken and marks the 1st time astronauts have been launched into orbit from US soil since the Space Shuttle was retired.

The new spacecraft itself is a pretty incredible feat of engineering, to be fair. It comes in two parts: one that provides the power for liftoff, and a second that houses the intrepid space explorers.
All being well, the first part will separate and return of its own accord to a landing ship in the sea off Florida. Then, the second part will continue the journey on into orbit, and dock with the International Space Station 24 hours later on.

This Demo-2 mission is a way of SpaceX showing that it can safely take astronauts to the International Space Station, and get them back in one piece.
