The multi-day trip isn't headed to a destination like the International Space Station, but instead is a free-flying mission tracing orbits that the crew hopes will go far from Earth.
As a centerpiece to the mission, the crew will attempt to perform the first-ever SpaceX spacewalk. Extravehicular activities, or EVAs, have been a regular part of government astronauts missions but no private venture has attempted an EVA before. The EVA is expected to last two hours long from start to finish.
