CAPE CANAVERAL, Fla. (AP) — A new private supply ship for the International Space Station remained stuck on the ground Saturday after rocket engine trouble led to a last-second abort of the historic flight.

All nine engines for the SpaceX Falcon 9 rocket roared to life Saturday morning. But with a mere half-second remaining before liftoff, the onboard computers automatically shut everything down. So instead of blasting off on a delivery mission to the space station, the rocket stayed on its launch pad amid a plume of engine exhaust.

Even NASA's most seasoned launch commentator was taken off-guard.

"Three, two, one, zero and liftoff," announced commentator George Diller, his voice trailing as the rocket failed to budge. "We've had a cutoff. Liftoff did not occur."

SpaceX president Gwynne Shotwell said that high combustion chamber pressure in engine No. 5 was to blame and that technicians would conduct an inspection later in the day. If the engine needs to be replaced, a spare is available.

Tuesday is the earliest that SpaceX can try again to send its cargo-laden Dragon capsule to the space station. The California-based company — formally known as Space Exploration Technologies Corp. — is targeting every few days for a launch attempt to save fuel in case of rendezvous problems at the space station. Wednesday also could be a launch option.

This was the first launch attempt by the several private U.S. companies hoping to take over the job of delivering cargo and eventually astronauts to the space station for NASA. Only governments have accomplished that to date: the United States, Russia, Europe and Japan.

NASA is looking to the private sector, in this post-shuttle era, to get American astronauts launching again from U.S. soil. SpaceX officials said that could happen in as little as three years, possibly four. Several other companies are in the running.

An estimated 1,000 SpaceX and NASA guests poured into the launching area in the wee hours of Saturday, hoping to see firsthand the start of this new commercial era. They left disappointed. The abort was especially disheartening given the perfect weather and the absence of any earlier countdown problems.

Shotwell was asked by a reporter whether she considered Saturday's abort a failure.

"This is not a failure," she said. "We aborted with purpose. It would be a failure if we were to have lifted off with an engine trending in this direction."

She added: "The software did what it was supposed to do" with the engine shutdown.

Everyone around town, at least, is rooting for a successful flight.

"Go SpaceX," read the sign outside Cape Canaveral City Hall. Until NASA's space shuttles retired last summer, the sign had urged on the launches of Discovery, Endeavour and, finally, Atlantis. Those ships are now relegated to museums.

Late last month, SpaceX conducted a test firing of the nine first-stage rocket engines at the pad. Each engine — including No. 5 — was "rock solid," Shotwell said.

The first flight of the Falcon 9 rocket from Cape Canaveral, in June 2010, encountered similar last-second engine trouble, but there was enough time to fix the problem and fly the same day. SpaceX has just a single second each day to launch this time around because of the space station rendezvous.

Six months after the initial Falcon 9 flight, SpaceX launched another rocket with a Dragon capsule that reached orbit. It was the first time a private company put a spacecraft into orbit and then recovered it. The newest Dragon also is meant to splash down into the Pacific, returning space station experiments and equipment.

For Saturday's launch attempt, SpaceX's billionaire founder, Elon Musk, was in the SpaceX Mission Control in Hawthorne, Calif. He helped create PayPal and founded SpaceX 10 years ago. He also runs Tesla Motors, his electric car company.

I wonder how much that aborted launch costs.... Just the fuel alone has to be pricey.

true but they only burned a fraction of it, those can usually be unloaded. its not like a SRB where once you light it, its fkn going going going!

CAPE CANAVERAL, Fla. (AP) — Private rocket maker SpaceX aimed for a Tuesday liftoff after fixing the engine problem that caused a launch abort over the weekend, stalling the world's first commercial space station supply flight.

Forecasters put the odds of good weather at 80 percent for the test flight. Launch time was 3:44 a.m. with a split-second window.

The California-based Space Exploration Technologies Corp., better known as SpaceX, is the first private business to attempt to launch a vessel to the International Space Station. The Dragon capsule atop the Falcon 9 rocket is filled with 1,000 pounds of food and other provisions.

All nine of the Falcon's engines ignited during the first launch attempt Saturday. But with just a half-second remaining before liftoff, on-board computers shut everything down because of high pressure in the combustion chamber of engine No. 5.

The problem was traced to a faulty valve. Engineers put in a new valve and declared the rocket ready to fly.

SpaceX is run by billionaire Elon Musk, the co-founder of PayPal. His company is in the lead of the NASA-sponsored competition to hand over space station cargo runs — and eventually astronaut ferry trips — to private business.

Musk said his Dragon capsules could be carrying astronauts to orbit in about four years. Until a private spacecraft is ready to fly, NASA astronauts will continue to ride Russian rockets to the space station.

The switch from government to commercial spaceflights is the cornerstone of President Barack Obama's exploration plan. The administration wants NASA spending its limited resources on missions beyond low-Earth orbit.

If launched Tuesday, the Dragon will reach the space station Thursday and undergo a series of practice maneuvers from more than a mile out. Then on Friday, the capsule will fly within reach of the station's 58-foot robot arm, which will snare it and berth it to the orbiting lab.

The arm will be operated by two of the six space station residents: American Donald Pettit and Andre Kuipers, who is Dutch.

"Ready to monitor the approaching Dragon spacecraft in bright sunlight and complete darkness," Kuipers said via Twitter on Monday. He posted a picture of the two crewmen awaiting the capsule. "Sunglasses, headlamp, reading glasses. Now for the launch."

The Dragon will spend a week at the space station before being cut loose and parachuting into the Pacific with experiments and equipment. None of the other visiting supply ships — from Russia, Europe and Japan — are designed to return intact.

You can get them for free at planned parenthood
