X-37B

Last week, the US Space Force posted a photo online from its uncrewed X-37B space plane's seventh mission, showing the orbital test vehicle above our planet in High Earth Orbit over 22,000 miles away. Now that's a selfie worth sharing.

The US Space Force's secret-but-not-really-secret spaceplane will carry out a novel maneuver called aerobraking to change its orbit. Instead of using thrusters, the robotic spacecraft will dip into the Earth's atmosphere to change its trajectory.
