Building on development for NASA’s commercial crew program, Space Adventures announced an agreement Tuesday with SpaceX to fly up to four paying space tourists on a standalone mission aboard a Crew Dragon spacecraft in late 2021 or 2022 that could reach an altitude two-to-three times higher than the International Space Station.

Boeing and SpaceX hope to launch commercial crew ferry ships on long-awaited test flights later this year, but both companies face major challenges getting the spacecraft certified before late 2019 when seats aboard Russian Soyuz spacecraft will no longer be easily available for NASA space station crews, officials told lawmakers Wednesday.

Opening a new era in American spaceflight, a Falcon 9 rocket streaked into space early Saturday, boosting the company’s first Crew Dragon spacecraft into orbit on an unpiloted test flight, the first launch of a commercially developed capsule intended to carry astronauts to and from the International Space Station.
