SpaceX Falcon 9/Dragon Launch Scrubbed

Early data shows that the chamber pressure on Engine #5 was high. The teams will continue to look at the data and assess a launch attempt on May 22. The team is safing the Falcon 9 rocket now. Next chance to launch is Tuesday at 3:44 am EDT (0744 GMT).

Falcon 9 first stage Merlin Engine number 5 chamber pressure was high, causing the cutoff at almost T-zero. The Falcon has nine Merlin engines in the first stage. All nine engines must be up and running at full thrust before liftoff can occur. Since engine 5 had high chamber pressure, the computer cutoff the launch sequence and shut down the the engines
