The SpaceX two-fer launch that was scheduled for today has been scrubbed. NBC News reports that the launch was postponed until Monday at the earliest due to a problem with the range-tracking system in Florida. That means an ambitious second attempt to land the Falcon 9 rocket’s first stage on an oceangoing platform will also have to be delayed. … Satellites such as the Advanced Composition Explorer and Solar and Heliospheric Observatory, which are already located at the L1 point, can provide up to an hour’s warning of major storms. Both those satellites are well past their anticipated lifetimes, however, and DSCOVR is designed to provide a much-needed backup. SpaceX’s two-stage Falcon 9 rocket will boost DSCOVR into a preliminary orbit, but it will take 110 days of in-space maneuvers to get the probe into the right position. This launch would mark the first time that SpaceX has sent a spacecraft so far, and it will be judged a success if DSCOVR reaches its intended orbit. The delayed launch could take place as soon as tomorrow (Monday) evening.
