SpaceX aborted the launch of its Falcon 9 rocket today due to problems with an Air Force radar tracker. The mission is designed to carry NASA’s Deep Space Climate Observatory, a space weather satellite, to space. It is also SpaceX’s second attempt to land its rocket back on Earth, which would be a major step in creating reusable rockets to bring down the cost of spaceflight.
Air Force tracking radar went down. Launch postponed to same time tomorrow.
