The Polaris missions are helping fast-track Elon Musk's Mars city, from testing spacesuits and a spacewalk to planning Starship's first crewed flight.

After accomplishing a number of space industry firsts, including the first-ever private astronaut spacewalk, the Polaris Dawn crew's Dragon spacecraft slashed down at 3:36 a.m. EDT Sunday morning off the coast of Dry Tortugas, Florida. Dry Tortugas is a small island located about 70 miles west of Key West in the Gulf of Mexico.
