The X-37B Orbital Test Vehicle, a 29-foot spacecraft resembling a mini space shuttle, is set to launch from Cape Canaveral, Florida, atop an Atlas V rocket. The mission's details remain largely classified, but it aims to test the Air Force's capabilities in launching, maintaining, and returning the spacecraft after extended periods in space, potentially lasting up to 270 days. The spacecraft will utilize lithium-ion batteries and solar panels for power, with a focus on evaluating battery performance during long missions. Speculation includes its potential role in replacing GPS satellites, although the X-37 is expected to operate unmanned. The launch has garnered local media coverage, highlighting public interest and visibility.
