After the last-minute aborting of a launch to the International Space Station over the weekend, Space X is ready to try again.  The private company has re-scheduled the launch of its  Falcon 9 rocket for Tuesday morning.

Technicians planned to replace a faulty engine valve Saturday night that is believed responsible for prompting the abort of the first launch attempt with a half-second remaining in the countdown, after all nine first-stage engines had ignited.

Computers detected high pressure in one engine’s combustion chamber, triggering an automatic shutdown just before the planned 4:55 a.m. EDT liftoff.

Analysis of the repaired engine and the potential for similar problems on its neighboring engines will continue Sunday.

“If things look good, we will be ready to attempt to launch on Tuesday,” SpaceX spokeswoman Kirstin Grantham said in a statement.

A launch Tuesday from Cape Canaveral Air Force Station’s Launch Complex 40 would occur at 3:44 a.m.

Preliminary forecasts show a 60 percent chance of favorable weather conditions.
