The American SpaceX is poised to blast off a Falcon 9 rocket today at 11.24 p.m. IST. It will launch from the Vandenberg Air Force Base on the California coast. It would be the first mission undertaken by the company since one of its vehicles exploded on the launch pad in September. <br/><br/>The return to operations will see SpaceX start to renew what was the original global handheld satellite phone network, run by Iridium. SpaceX had hoped to get its first Falcon of 2017 up and away a week ago, but stormy weather made that impossible. Today's forecast looks far more favourable.
