CAPE CANAVERAL, Fla. (AP) — The Space Force has launched the military’s mystery space plane again, this time with an extra load of science experiments. The X-37B rocketed into orbit Sunday morning from Cape Canaveral, Florida, a day late because of bad weather. It’s the sixth flight of an X-37B, which resembles a mini shuttle and operates remotely. Officials aren’t saying how long the spacecraft will remain in orbit. The previous mission lasted a record two years. The winged spacecraft resembles NASA’s old shuttles, but is smaller at 29 feet long. The one just launched features an extra compartment for experiments.
