Axiom Space launched Ax-2 today, the second of four planned private missions to the space station. Of the four people on this trip (a seat reportedly costs about $55 million), mission commander Peggy Whitson is the most experienced, with three previous trips to the ISS under her belt and 665 days in space, more than any other American astronaut.

The Dragon spacecraft is scheduled to dock with the ISS on Monday morning at around 9:16AM ET.
