Elon Musk's SpaceX on Sunday postponed launch of an upgraded Falcon 9 rocket and an attempt to land the booster at the launch site, saying the tricky touchdown would have a better chance of success if delayed for 24 hours.
A smooth landing would provide a big boost to Musk's Space Exploration Technologies, or SpaceX, and its long-term ambition of refurbishing and reusing its rockets, an advance that could slash launch costs.
The mission, rescheduled for 8:33 p.m. ET on Monday, is the first for SpaceX since June 28, when the Falcon 9 failed during an attempt to deliver cargo to the International Space Station for NASA.
The revamped rocket will carry 11 small communications satellites for ORBCOMM Inc, which provides messaging services for retailers, shipping containers and others.
