The U.S. Space Force's X-37B spaceplane landed at Vandenberg Space Force Base this week, after spending 434 days in orbit. Although its mission is classified, Space Force says that it was on a highly elliptical orbit, completing a range of test and experimentation objectives. This was the 7th mission for the X-37B, and it was testing its experiments "across orbital regimes." Whatever that means. It's classified.
