SpaceX’s attempt to launch their Falcon 9 rocket with the Dragon spacecraft was aborted by the computer at T-0 due to a high pressure reading on engine 5 of the first stage. The rocket’s nine main engines were ignited, but were automaticalaly shut down before liftoff. The vehicle was safed with no apparent other issues. SpaceX and NASA are now looking at the next launch window, which is on Tuesday, May 22 at 0744 UTC, 3:44 EDT. Computer checks all launch components just prior to launch, which is an extra safety feature of the Falcon 9, so the good part of the abort is knowing that all the systems worked as designed to prevent a liftoff that wasn’t within the designed parameters. Since this is a test flight, the SpaceX team likely thinks of this a successful launch abort as opposed to a failed launch.
See the video below:
“I have watched and participated in more scrubs of the shuttle than I would have liked, but it’s just part of the launch business,” said Michael Lopez-Alegria, former shuttle and ISS astronaut and President of the Commercial Space Federation. “I was extremely impressed with professionalism displayed by the SpaceX launch team in the moments after the scrub to safe the vehicle. We will have to wait for the team to perform the technical analysis of what caused the apparent high pressure in one of the engine’s combustion chambers and for SpaceX and NASA to decide when the next attempt will occur. This is not the outcome we were hoping for, but far better to detect and react to the problem while still in the pad than to have to deal with it in flight.”
When launched, Dragon will be the first commercial spacecraft to go to the International Space Station for cargo resupply.
We’ll have more details later, as SpaceX and NASA will have a press briefing later this morning.

Saturday morning’s launch window for SpaceX’s historic test flight to the International Space Station lasts just one second. Company President Gwynne Shotwell predicted they have “better than a 50-50 shot on whether we lift off tomorrow,” she said at a press conference today, adding, “If we lift off, we’ll get to orbit.”
Shotwell and NASA officials outlined a myriad of systems and activities that have to go perfectly for the launch take place, and then it will be non-stop action for the duration of the flight to orbit and ultimately the berthing of Dragon to the ISS.
Launch is set for 08:55 UTC on May 19 (4:55 AM Eastern/1:15 AM Pacific.) Here’s a timeline of activities so you can follow along while you watch the launch:
08:45 UTC: The Terminal Count begins at T-10 minutes before launch
08:52:30 (T-00:02:30) SpaceX Launch Director verifies GO
T-00:00:03 Engine controller commands engine ignition sequence to start
09:04:34 (T+0:09:35) Dragon separates from Falcon 9 and initializes its propulsion system.
09:06:30 (T+0:11:30) Deploy solar array
09:08 (T+0:13) On-Orbit Operations begin
Shotwell said that 2 hours and 26 minutes into the flight is the Guidance Navigation and Control (GNC) door is opened on the exterior of the capsule. “This is a key new feature for this mission, which basically exposes the Proximity Operations Sensors to space so we can see the ISS as we are approaching and allow us to get close enough to berth,” Shotwell explained. “Our star trackers also get a view of space at this time, so this is a very critical operation”
The first 24 hours into the flight, Dragon will be catching up or phasing with the ISS. On Flight Day 2 at about 40 hours into the flight, Dragon will the ISS and do a “flyunder” of the station and for about 10 hours, do some maneuvers to demonstrate the ability to stationkeep and fly about the ISS, all the while in contact with the space station and Mission Control. There will be a relative GPS demonstration, and the “critical operations and tests we need to execute and show NASA the data so that we can show them everything is working,” Shotwell said.
Then, Dragon will perform a re-rendezvous with a flyunder of about 2.5 kilometers below the station, then maniever in front of the station, raise up and go back around.

Don Pettit and Andre Kuipers will be working Canadarm2 on the station, and will grapple Dragon on May 22, berthing it to the Harmony node.
If there are any problems, NASA, SpaceX and the crew on the ISS has the ability to call an abort, or Dragon could autonomously abort.
But everyone is hoping for smooth sailing.

“By hour 75, if all is going well, we should be berthed to the station, which should be really great,” Shotwell said. “I know everyone at SpaceX is excited for this mission.”
The SpaceX launch webcast is scheduled for 1:15 AM Pacific / 4:15 AM Eastern / 08:15 UTC on May 19 at the SpaceX website, or you can watch on NASA TV starting at 08:30 UTC.
Right now the weather looks favorable for launch. If SpaceX can’t launch on the 19th, they can try again On May 22, 25th and 29th, which provide good launch opportunities. Other less than optimal dates for launch are the 23rd, 26th, and then the ISS enters into a period of high beta angle of the Sun, where there would be excessive heat surrounding the station, so the 29th of May is last date for awhile that SpaceX could launch Dragon.

With less than a day left before SpaceX’s historic launch of the first commercial vehicle to the ISS, slated for 4:55 am EDT on Saturday, May 19, here’s a video of what will happen once the Falcon lifts off.
(Part of me really wishes that they’ll be pumping out some dramatic music when it launches!)

The video, created by NASA in 2011, shows the events that will take place from the initial launch at SpaceX’s Cape Canaveral facility to the release of the Dragon capsule and its eventual docking with the ISS on Tuesday, as well as its return to Earth (yes, it’s reusable!)
The Dragon capsule contains 674 lbs (305 kg) of food and supplies for the Expedition 31 crew.
In addition to what’s aboard Dragon, the Falcon rocket will also be taking the cremated remains of 308 people — including Star Trek actor James Doohan and NASA astronaut Gordon Cooper — into space, via a private company called Celestis.

In less than 48 hours, SpaceX is primed to make history and launch the first ever commercial rocket and spacecraft to the International Space Station (ISS) early Saturday morning on May 19.
Following today’s Launch Readiness Review (LRR), SpaceX was just given the official “GO” from NASA to proceed with the blastoff of the Falcon 9 at 4:55 a.m. EDT (0855 GMT) from Space Launch Complex-40 on Cape Canaveral Air Force Station in Florida. This also marks the first night time liftoff of the Falcon 9 rocket.
“Just passed final launch review with NASA”, SpaceX CEO Elon Musk tweeted this evening. “All systems go for liftoff on Sat morn”.
The SpaceX developed Dragon cargo resupply spacecraft is bolted on top of the two stage Falcon 9 rocket and stands 157 feet tall for the mission dubbed “COTS 2”. The Falcon 9 booster generates 1 million pounds of thrust
The official Air Force weather forecast gives a 70% chance of acceptable conditions for launch. The primary concern for launch day is a violation of the Cumulus Cloud Rule. On the heels of a significant drought, stormy weather has rolled into the Florida Space Coast and thunder is striking the area at the moment.
In the event of a launch scrub, the next launch opportunity comes in three days on May 22.
The launch will be broadcast live on NASA TV and via SpaceX Webcast at http://spacex.com

Technicians plan to roll the Falcon 9/Dragon duo out to the seaside launch pad tonight. The rocket will be moved on rail tracks about 600 feet from the processing hanger to the pad and vertically erected.
The purpose of Dragon is to carry supplies up to orbit and dock at the ISS and partially replace the capabilities of NASA’s now retired space shuttle. Dragon is a commercial spacecraft designed and developed by SpaceX.
SpaceX is under contract with NASA to conduct twelve resupply missions to the ISS to carry cargo back and forth for a cost of some $1.6 Billion.
The Dragon spacecraft is loaded with nearly 1200 pounds of non-critical cargo such as food and clothing on this flight. A collection of student experiments, commemorative patches, pins and emblems will also be on board Dragon’s upcoming test flight.
On Friday, Ken will be reporting from Space Launch Complex-40 on Cape Canaveral.

[/caption]SpaceX has announced that the upcoming launch of the firms Falcon 9 and Dragon spacecraft on the commercial COTS 2 mission has been postponed to a new target date of no earlier than May 19 with a backup launch date of May 22.
On May 19, the Falcon 9 rocket would lift off on its first night time launch at 4:55 a.m. EDT (0855 GMT) from Space Launch Complex-40 on Cape Canaveral Air Force Station in Florida.
Two launch opportunities had been available this week on May 7 and May 10, following the most recent slip from April 30.
SpaceX managers made the decision – in consultation with NASA – to delay the COTS 2 launch in order to complete further highly critical testing and verifications of all the flight software requirements for the Dragon spacecraft to safely and successfully carry its mission of rendezvousing and docking with the International Space Station (ISS).
“SpaceX and NASA are nearing completion of the software assurance process, and SpaceX is submitting a request to the Cape Canaveral Air Force Station for a May 19th launch target with a backup on May 22nd,” said SpaceX spokesperson Kirstin Grantham.
“Thus far, no issues have been uncovered during this process, but with a mission of this complexity we want to be extremely diligent.”
May 10 was the last window of opportunity this week because of the pending May 14 blast off of a new Russian Soyuz TMA-04M capsule from the Baikonur Cosmodrome in Kazakhstan with three fresh crew members bound for the ISS which will restore the outpost to a full crew complement of 6 human residents.
The Falcon 9 and Dragon can only be launched about every three days.
The purpose of Dragon is to carry supplies up to and back from the ISS. Dragon is a commercial spacecraft developed by SpaceX and designed to replace some of the cargo resupply functions previously conducted by NASA’s fleet of prematurely retired Space Shuttle orbiters. At this moment the US has zero capability to launch cargo or crews to the ISS.

In response to the SpaceX announcement, NASA issued the following statement from from William Gerstenmaier, associate administrator for Human Exploration and Operations at the agency’s Headquarters in Washington:
“After additional reviews and discussions between the SpaceX and NASA teams, we are in a position to proceed toward this important launch. The teamwork provided by these teams is phenomenal. There are a few remaining open items, but we are ready to support SpaceX for its new launch date of May 19.”
SpaceX is under contract with NASA to conduct twelve resupply missions to the ISS to carry cargo back and forth for a cost of some $1.6 Billion.
Dragon is loaded with nearly 1200 pounds of non-critical cargo such as food and clothing on this flight.
The COTS 2 mission has been repeatedly delayed since the originally planned target of mid-2011 when SpaceX requested that the COTS 2 and 3 flights be combined into one mission to save time. The first Dragon docking to the ISS was initially planned for the COTS 3 mission.

It was short but sweet. SpaceX conducted a 2-second static fire test of their Falcon 9 rocket that will send the first COTS flight to the International Space Station. “Woohoo, rocket hold down firing completed and all looks good!!” Tweeted SpaceX CEO and founder Elon Musk. SpaceX’s Twitter feed said with the successful firing, engineers will now review data as they continue to prepare for the upcoming mission, slated to launch on May 7.
A first attempt was aborted with 30 seconds left in the countdown, due to “overly restrictive redline on second stage engine position.” Engineers recycled all the rocket’s systems and began another countdown.
Fire and smoke erupted just briefly from the base of the rocket, and there seemed to be a bit of confusion on the webcast, as the word “abort” was used, but then there was word of success and the webcast ended abruptly.

For the static fire test, the nine Merlin engines on the first stage of the Falcon 9 rocket were ignited at 20:15 UTC (4:15 p.m. EDT). The test was part of a full dress rehearsal for the SpaceX team. Last week was a final full simulation between NASA and SpaceX for the series of demonstration maneuvers and tests the Dragon capsule will make as it approaches the ISS; then the astronauts on board will capture and berth the cargo capsule to the Harmony module’s Earth-facing docking port.
If the abort problem had occured on the launch day, there would be no second attempt; there is no recycling of the systems for an actual launch. Additionally, the Falcon 9 can only attempt launch every 3 days because of limited propellant on Dragon capsule. SpaceX needs to ensure there is enough propellant on board Dragon for the pre-berthing maneuvers and tests.
If the Falcon 9 launch is delayed by weather or technical problems, another attempt could be made on May 10, but after that they would have to until after the launch of a Russian Soyuz spacecraft that will bring three new crew members to the space station. That mission is scheduled for launch from the Baikonur Cosmodrome in Kazakhstan on May 14, and would dock two days later.
The launch of the Falcon 9 and Dragon has been delayed from its initial planned flight in February, but with today’s apparently successful test, SpaceX and NASA are hopeful for going forward with next week’s launch.
SpaceX is one of two companies, along with Orbital Sciences, competing for contracts to deliver cargo to low Earth orbit for NASA under the Commercial Orbital Transportation System program.
The launch is currently set for 13:38 UTC (9:38 a.m. EDT) on Monday.

On Monday, April 30, SpaceX (Space Exploration Technologies) is all set to conduct a critical static engine test fire of the Falcon 9 rocket at the firm’s launch pad on Cape Canaveral, Florida.
If all goes well, SpaceX and NASA are targeting a May 7 liftoff of the rocket and Dragon spacecraft at 9:38 AM, bound for the International Space Station (ISS). This launch signifies the first time that a commercial company is attempting to dock at the ISS.
The Falcon 9 rocket with the Dragon bolted on top was rolled out to the pad at Space Launch Complex 40 (SLC-40) on the transporter-erecter on Sunday morning (April 29), SpaceX spokesperson Kirstin Grantham told Universe Today.
“The Falcon 9 is vertical. Fueling begins Monday,” said Grantham.
On Sunday night, SpaceX CEO Elon Musk tweeted: “Dragon review completed. All systems now ready for full thrust hold down firing on Monday.”
Today the 180 foot long rocket was moved about 600 feet on rail tracks from the processing hanger to Pad 40 in anticipation of the engine test firing.
During the hotfire test, all nine of the powerful liquid fueled Merlin 1C first stage engines will be ignited at full power for two seconds as part of a full launch dress rehearsel for the flight, dubbed COTS 2. SpaceX engineers will run through all launch procedures on Monday as though this were an actual launch on launch day.
This is the second Falcon 9 launch for NASA as part of the agency’s Commercial Orbital Transportation Services program designed to enable commercial firms to deliver cargo to the ISS following the retirement of NASA’s fleet of Space Shuttles. The first Falcon 9 COTS test flight took place in December 2010.

With the upcoming historic launch of the SpaceX Dragon capsule to the International Space Station, astronauts in orbit have been getting ready for the first commercial spacecraft that will bring supplies to the station. Astronauts Don Pettit and André Kuipers will be manually capturing and berthing the Dragon capsule, using the ISS’s Canadarm2. Originally, current station commander Dan Burbank was to be the main arm operator, but with the delay in Dragon’s launch (it was originally scheduled for February 2012), Burbank will already be back on Earth by the time Dragon reaches the station, currently scheduled for May 3. So now, Pettit and Kuipers have had to take over the duties and learn their new jobs while in space. Without the high-tech simulators that NASA has at Johnson Space Center, how do the astronauts prepare and practice for this important event?
“We have a really neat capability here on Station,” Pettit said during a press conference last week. “I have it set up all the time, so I wake up in the morning and have a bag of coffee in my mouth and a cinnamon scone in one hand and flying the simulator with the other.”
The crew actually has two ways to practice for Dragon’s arrival.
“One is actually flying (practicing with) the Canadarm, which is the world’s best trainer,” Pettit said, “and then on station we have two space station computers which double as an Arm simulator, and it has a full set of the Arm hand controllers – the setup, which we call Robot allows us to fly track and capture trajectories just as if we were in the simulators in Houston.”
Initially Burbank would have been the main arm officer, with Pettit and Kuipers assisting. Now, Pettit and Kuipers will have to complete the task themselves, with the two of them doing all the things that the three of them were originally trained to do.
For the capture and berthing, Pettit and Kuipers will be in the Cupola, with Pettit as prime operator and Kuipers as second arm operator. “We will have arm operation in the (Destiny) lab as a ‘hot backup’ just in case of contingencies, and we can activate it there if needed.”
The two astronauts will use the Station’s Canadarm2 to first grab the spacecraft and then maneuver it into place to mate with the Harmony module’s Earth-facing docking port.
Pettit said the on-orbit training has been invaluable. “It is really good to have that type of capability,” he said.
The following animation from the Canadian Space Agency shows just how complex it is to capture a Dragon in space.
SpaceX’s launch and Dragon’s arrival will be the premiere test flight in NASA’s new strategy to resupply the ISS with privately developed rockets and cargo carriers under the Commercial Orbital Transportation Services (COTS) initiative. Even though it is technically a est flight, NASA isn’t about to pass up an opportunity to send supplies to the station. Dragon will carry about nearly 521 kg (1,150 pounds) of cargo, mainly food and some spare parts for the ISS. When Dragon departs, the station crew will load nearly 680 kg (1,500 pounds) of cargo to be sent back to Earth, since the Dragon capsule won’t burn up in the atmosphere like other supply ships — it will be recovered in the ocean.
As Jon Stewart from the Daily Show noted (although not quite correctly), four entities have launched rockets into space: the US, China, the Soviet Union (Russia) and Elon Musk. “Well, it wasn’t just me,” Musk replied humbly. Watch the entire interview here of Elon Musk on the Daily Show, where he discusses SpaceX’s upcoming test flight of their unmanned Dragon capsule to the International Space Station, sending humans to Mars, energy problems, and whether he is one of the X-Men.

So much for the idea that space capsules are cramped and can only carry a limited crew. SpaceX revealed a prototype for their new crew cabin design, as they conducted a joint daylong review with NASA of the Dragon crew vehicle layout. In this configuration, the Dragon will be able to carry a crew of seven, the same number the space shuttle could carry. Using a Dragon engineering model equipped with seats and representations of crew systems, they were able to get assessments and feedback from engineers and four NASA astronauts on interior amenities such as lighting, environmental control and life support systems, displays, cargo racks, and the all important seating system. The evaluators participated in human factors assessments which covered entering and exiting Dragon under both regular and emergency (that’s ‘off-nominal’ in NASA-speak) scenarios, as well as reach and visibility evaluations.
See more images from the review, below, along with a video from the initial tests of the SuperDraco engines that will power the launch escape system.
Plus, as a heads-up, SpaceX CEO Elon Musk will be on the US television show “60 Minutes” on Sunday, March 18, 2012. You can see a preview here, (which includes a touching scene of Musk talking about his heroes) and check your local listings here.

Even with all seven crewmembers in their seats, there is enough interior space for three additional people to stand and assist the crew with their launch preparations — or for the CEO to kibitz with the crew.

The seven seats mount to strong, lightweight supporting structures attached to the pressure vessel walls. Each seat can hold an adult up to 1.95 meters tall (6 feet 5 inches) and weighing 113 kg (250 lbs), and has a liner that is custom-fit for each crewmember.
