SpaceX Delays Falcon 9 Launch Attempt To Dec. 9

SpaceX will delay the launch attempt of the Falcon 9 rocket until at least Thursday, Dec. 9. At a press conference today, company president Gwynne Shotwell said a final review of closeout photos this morning found some indications of a potential issue on a second stage nozzle. Reports from journalist Robert Pearlman on Twitter said the Falcon 9 had been lowered from the vertical launch position. And Shotwell said if they have to replace the nozzle, the launch would be no earlier than Friday, Dec. 10.

“During an inspection of final closeout photos they determined there were some indications in a weld joint that they wanted to take some additional steps to look at,” said Shotwell, “and they brought the vehicle down to horizontal. I believe it is back up to vertical now.” When asked for details, Shotwell said “porosity and potential cracking in a weld joint.”

There were some weather concerns for the early to mid part of this week, but the weather improves later in the week, so perhaps the delay was going to happen anyway.

This is the first demonstration launch for NASA’s Commercial Orbital Transportation Services (COTS) program, with a functional Dragon capsule.

SpaceX CEO Elon Musk has said he thinks they have a 70% chance of successful first flight of the Falcon 9/Dragon capsule.

Shotwell agreed, saying history predicts SpaceX will likely have a substantial issue to deal with in this test flight.

“Given we got Falcon 9 to orbit on our first test flight, I’d say 70% for this flight, too,” she said.

At the press conference, NASA’s Phil McAlister, from the Office of Program Analysis and Evaluation, provided some insight into NASA’s thinking on if there were to be substantial problems with any of the COTS test flights. “We expect anomalies and the purpose of a test flight is to find the problems,” he said. “We won’t know until the end of the program if we’ve been completely successful, but to date this has been remarkably successful. Even if we have a bad day on this flight, for example, we expect to move forward. It is not a condition that every test flights be successful. We are committed to learn from each flight. But we would certainly like to have a a successful flight. So far we are on very good track and we will learn a lot from this test flight and move forward regardless of the outcome.”

The key milestones for this flight are a successful launch, separation of the Dragon vehicle from the rocket and successful reentry of Dragon.

No matter the outcome of this flight, SpaceX plans on having next Dragon flight ready by late spring/early summer 2011.

For the future, McAlister also said that he believe competition is very important, and that NASA would like to have at least 2 cargo service companies. “We would like to have routine, cost effective cargo services to LEO by 2020.”

Shotwell said it would be at least two and a half to three years after the cargo program is initiated is the first chance for astronauts to be ferried on board the Dragon capsule.

SpaceX Test Fire Aborted

A static test firing of the SpaceX Falcon 9 rocket was cut short as computer systems shut down the first-stage engines before the test was complete. The firing was only going to last two seconds, but the engines ran for 1.1 sec due to high engine chamber pressure, according to SpaceX. Space News reported that engineers are analyzing the data and that a second attempt is likely to occur tomorrow, Dec. 4. This abort occurred just four days before SpaceX is schedule to conduct the maiden launch of its Dragon space capsule on board the medium-class Falcon 9.

This video is from SpaceX’s webcast of the firing and unfortunately is a bit jumpy.

The first-stage firing was part of a dress rehearsal conducted in preparation for the planned Dec. 7 launch, the first of three increasingly complicated flight demonstrations of Falcon 9 and Dragon under the company’s Commercial Orbital Transportation Services (COTS) agreement with NASA.

In a press release from SpaceX from Dec. 2, the company said the rehearsal would “exercise the countdown processes and end after the engines fire at full power for two seconds, with only the hold-down system restraining the rocket from flight.”

After the test, SpaceX said they would conduct a thorough review of all data as engineers make final preparations for the upcoming launch.

The rockets uses kerosene and liquid oxygen, and the nine Merlin engines generate one million pounds of thrust in vacuum.

The $278 million COTS agreement has SpaceX developing and demonstrating hardware capable of ferrying cargo to and from the International Space Station.

We’ll post more information about the abort as it becomes available.

Dragon Drop Tests and Heat1X-Tycho Brahe Set to Launch – SpacePod 2010.08.24

Spirialing ‘UFO’ Over Australia Was Likely Falcon 9 Rocket


Logical explanations take all the fun out of UFO’s. After the Falcon 9 rocket launched successfully, later, over on the other side of the world, people in Australia saw a spiraling object in their early morning skies, about 6 am local time. Geoffrey Wyatt, from the Sydney Observatory, said it appeared to have been the Falcon 9 rocket, which launched about an hour earlier.

Another image below.

The image is from the 9MSN website in Australia, where you can see more images.

If you recall, there was another spiraling rocket that created a visual sensation over Norway in December of 2009.

Falcon 9 Launch Gallery; ‘Fantastic Day,’ P–G Singularity and More

Universe Today photographer Alan Walters was on hand for Friday’s spectacular and picture-perfect launch of SpaceX’s Falcon 9 rocket. Enjoy a gallery of images, including this great shot of a Prandtl–Glauert singularity, or shock cone that formed around the rocket, which sometimes occurs when a sudden drop in air pressure occurs when rockets or aircraft are traveling at transonic speeds.

“This has really been a fantastic day,” said an exuberant Elon Musk, CEO of SpaceX, speaking with reporters after the flight. “It’s been one of the best days of my life. It’s certainly been one of the greatest days for the people of SpaceX.”

Falcon 9 Flight Hardware Arrives at Cape Canaveral

[/caption]
SpaceX announced Thursday that all flight hardware for the first launch of the Falcon 9 rocket has arrived at the SpaceX launch site, at Space Launch Complex 40 (SLC-40), in Cape Canaveral, Florida, which I was able to see earlier this week. The final delivery included the Falcon 9 second stage, which recently completed testing at SpaceX’s test facility in McGregor, Texas. SpaceX has now initiated full vehicle integration of the 47 meter (154 feet) tall, 3.6 meter (12 feet) diameter rocket. In an upcoming launch, possibly as early as March, SpaceX will test their the cargo- and crew-carrying ability, using a Dragon spacecraft qualification unit. Since SpaceX is poised to figure prominently in the future of human spaceflight, the upcoming test flight is crucial, both for SpaceX and NASA.

“We expect to launch in one to three months after completing full vehicle integration,” said Brian Mosdell, Director of Florida Launch Operations for SpaceX. “Our primary objective is a successful first launch and we are taking whatever time necessary to work through the data to our satisfaction before moving forward.”

Following full vehicle integration, SpaceX will conduct a static firing to demonstrate flight readiness and confirm operation of ground control systems in preparation for actual launch.

Though designed from the beginning to transport crew, SpaceX’s Falcon 9 launch vehicle and Dragon spacecraft will initially be used to transport cargo. Falcon 9 and Dragon were selected by NASA to resupply the International Space Station (ISS) once Shuttle retires. The $1.6B contract represents 12 flights for a minimum of 20 tons to and from the ISS with the first demonstration flights beginning in 2010.
