Breaking News! SpaceX launch to space station on hold pending final tests

The launch of a commercial cargo ship making its first flight to the International Space Station is expected to slip a week or so to give engineers more time to complete pre-flight testing and analysis, Space Exploration Technologies, or SpaceX, announced late today.The company had been aiming to launch its Falcon 9 rocket and Dragon cargo capsule on April 30. A second launch opportunity was available May 3.
Last week, NASA managers tentatively cleared the SpaceX rocket and capsule for launch pending completion of testing and a final review of open items and overnight Sunday, company founder and chief designer Elon Musk said in a Twitter posting: “Just completed the rocket rollout review at SpaceX HQ in California. Almost time to launch. Pucker factor increasing…”
But this afternoon, after a review of the Dragon systems, Musk tweeted: “Am pushing launch back approximately a week to do more testing on Dragon docking code. New date pending coordination with NASA.”
Company spokeswoman Kirstin Brost Grantham said in a later e-mail: “After reviewing our recent progress, it was clear that we needed more time to finish hardware-in-the-loop testing and properly review and follow up on all data. While it is still possible that we could launch on May 3, it would be wise to add a few more days of margin in case things take longer than expected. As a result, our launch is likely to be pushed back by one week, pending coordination with NASA.”
