SpaceX's private Polaris Dawn astronauts beam photos to Earth using Starlink satellites

Four people in blue flight suits laugh and smile as they float in zero gravity.

The private Polaris Dawn astronauts keep notching milestones in Earth orbit.

The four-person Polaris Dawn mission launched aboard a SpaceX Crew Dragon capsule early Tuesday morning (Sept. 10). Later that day, the astronauts got farther from Earth — 870 miles (1,400.7 kilometers) — than any crewed mission since the Apollo era.
