“Four private citizens are set to launch on an ambitious, first-of-its-kind space mission next week that is expected to include the first spacewalk conducted entirely by a commercial crew.

The mission, dubbed Polaris Dawn, is scheduled to lift off Monday from NASA’s Kennedy Space Center in Florida sometime between 3:30 a.m. and 7 a.m. ET…

They will ride into space in a SpaceX Crew Dragon capsule atop a Falcon 9 rocket. The plan for the five-day mission is to send them to an orbital altitude more than three times higher than the International Space Station — the highest that humans have reached since the final Apollo moon mission in 1972.

Three days into the flight should come the spacewalk, in which two crew members will exit the capsule on a tether for up to 20 minutes. Previously, only astronauts from government space agencies have conducted spacewalks to build or upgrade space stations in orbit, repair satellites and complete science experiments.”
