(FloridaToday.com) -11:20 update:SpaceX has decided to wave off a launch attempt today, and is now targeting Tuesday.

"All known rocket anomalies resolved," SpaceX CEO Elon Musk said on Twitter this morning. "Will spend another day rechecking to be sure."

He said the next attempt would be Tuesday evening, with Wednesday as a backup.

There is a 90 percent chance of weather cooperating for a Tuesday or Wednesday launch. Stay tuned for an updated launch time.

Technical issues thwarted the first two launch attempts, last Monday and Thursday.

On Thanksgiving, the Falcon 9 booster's nine engines fired briefly, but cut off when computers sensed thrust building more slowly than expected.

SpaceX CEO Elon Musk said the abort was caused by oxygen in the ground-side igniter system. He tweeted this weekend that technicians replaced the gas generator on one of the rocket's nine engines as a precautionary measure.

Previous udpate

SpaceX may make a third attempt today to launch its upgraded Falcon 9 rocket carrying a communications satellite from Cape Canaveral.

There is a 70 percent chance of weather cooperating for the 5:41 p.m. launch, the opening of a window that extends to 7:07 p.m. The official weather forecast predicts that clouds and rain should have cleared the Space Coast by launch time. The biggest concern: thick clouds.

The weather outlook gets even better Tuesday with a 90 percent chance of conditions acceptable for launch.

Previous report

SpaceX is targeting Monday for a third attempt to launch the SES-8 communications satellite from Cape Canaveral Air Force Station, the company said today.

"Rocket engines are healthy, but cleaning turbopump gas generators will take another day," CEO Elon Musk tweeted. "Aiming for Mon eve launch."

The launch window Monday would open at 5:41 p.m. EST, and there's a 60 percent chance of favorable weather conditions.

In another Twitter message today, Musk said the abort was caused by oxygen in the ground-side igniter system.

Launching Sunday was not an option. As with the two days before Thanksgiving, the Federal Aviation Administration would not close the air space because of the high volume of air traffic around the holiday.

SpaceX is attempting to launch its upgraded Falcon 9 rocket for the first time from Florida. The 224-foot rocket is carrying its first commercial payload, aiming for an orbit more than 22,000 miles over the equator.

The launch would be the first of a commercial communications satellite from the Cape in four years.
