[/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.
The first test launch of a commercially built spacecraft to the International Space Station has been delayed by its builder, Space Exploration Technologies or SpaceX, in order to carry out additional testing to ensure that the vehicle is fully ready for the high stakes Earth orbital mission.
SpaceX and NASA had been working towards a Feb. 7 launch date of the company’s Dragon spacecraft and announced the postponement in a statement today (Jan. 16).
A new target launch date has not been set and it is not known whether the delay amounts to a few days, weeks or more. The critical test flight has already been rescheduled several times and was originally planned for 2011.
“In preparation for the upcoming launch, SpaceX continues to conduct extensive testing and analysis, said SpaceX spokeswoman Kirstin Grantham in the statement.
“We [SpaceX] believe that there are a few areas that will benefit from additional work and will optimize the safety and success of this mission.”
“We are now working with NASA to establish a new target launch date, but note that we will continue to test and review data. We will launch when the vehicle is ready,” said Grantham.
Dragon’s purpose is to ship food, water, provisions, equipment and science experiments to the ISS.
The demonstration flight – dubbed COTS 2/3 – 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.
The Dragon will blast off atop a Falcon 9 booster rocket also built by SpaceX and, if all goes well, conduct the first ever rendezvous and docking of a privately built spacecraft with the 1 million pound orbiting outpost.
After closely approaching the ISS, the crew will grapple Dragon with the station’s robotic arm and berth it to the Earth-facing port of the Harmony node.
“We’re very excited about it,” said ISS Commander Dan Burbank in a recent televised interview from space.
Since the demonstration mission also involves many other first time milestones for the Dragon such as the first flight with integrated solar arrays and the first ISS rendezvous, extra special care and extensive preparatory activities are prudent and absolutely mandatory.
NASA’s international partners, including Russia, must be consulted and agree that all engineering and safety requirements, issues and questions related to the docking by new space vehicles such as Dragon have been fully addressed and answered.
William Gerstenmaier, NASA’s associate administrator for the Human Exploration and Operations Mission Directorate recently stated that the launch date depends on completing all the work necessary to ensure safety and success, “There is still a significant amount of critical work to be completed before launch, but the teams have a sound plan to complete it.”
“As with all launches, we will adjust the launch date as needed to gain sufficient understanding of test and analysis results to ensure safety and mission success.”
“A successful mission will open up a new era in commercial cargo delivery to the international orbiting laboratory,” said Gerstenmaier.
SpaceX is also working on a modified version of the spacecraft, dubbed DragonRider, that could launch astronaut crews to the ISS in perhaps 3 to 5 years depending on the amount of NASA funding available, says SpaceX CEO and founder Elon Musk
SpaceX’s Dragon spacecraft has gotten its wings and is set to soar to the International Space Station (ISS) in about a month. NASA and SpaceX are currently targeting a liftoff on Feb. 7 from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida.
Dragon is a commercially developed unmanned cargo vessel constructed by SpaceX under a $1.6 Billion contract with NASA. The Dragon spacecraft will launch atop a Falcon 9 booster rocket also built by SpaceX, or Space Exploration Technologies.
The Feb. 7 demonstration flight – dubbed COTS 2/3 – represents the first test of NASA’s new strategy to resupply the ISS with privately developed rockets and cargo carriers under the Commercial Orbital Transportation Services (COTS) initiative.
Following the forced retirement of the Space Shuttle after Atlantis final flight in July 2011, NASA has no choice but to rely on private companies to loft virtually all of the US share of supplies and equipment to the ISS.
The Feb. 7 flight will be the first Dragon mission actually tasked to dock to the ISS and is also the first time that the Dragon will fly with deployable solar arrays. The twin arrays are the primary power source for the Dragon. They will be deployed a few minutes after launch, following Dragon separation from the Falcon 9 second stage.
The solar arrays can generate up to 5000 watts of power on a long term basis to run the sensors and communications systems, drive the heating and cooling systems and recharge the battery pack.
SpaceX designed, developed and manufactured the solar arrays in house with their own team of engineers. As with all space hardware, the arrays have been rigorously tested for hundreds of hours under the utterly harsh conditions that simulate the unforgiving environment of outer space, including thermal, vacuum, vibration, structural and electrical testing.
The two arrays were then shipped to Florida and have been attached to the side of the Dragon’s bottom trunk at SpaceX’s Cape Canaveral launch processing facilities. They are housed behind protective shielding until commanded to deploy in flight.

I’ve toured the SpaceX facilities several times and seen the Falcon 9 and Dragon capsule launching on Feb. 7. The young age and enthusiasm of the employees is impressive and quite evident.
NASA recently granted SpaceX the permission to combine the next two COTS demonstration flights into one mission and dock the Dragon at the ISS if all the rendezvous practice activities in the vicinity of the ISS are completed flawlessly.
The ISS crew is eagerly anticipating the arrival of Dragon, for whch they have long trained.
“We’re very excited about it,” said ISS Commander Dan Burbank in a televised interview from on board the ISS earlier this week.
The ISS crew will grapple the Dragon with the station’s robotic arm when it comes within reach and berth it to the Earth-facing port of the Harmony node.
“From the standpoint of a pilot it is a fun, interesting, very dynamic activity and we are very much looking forward to it,” Burbank said. “It is the start of a new era, having commercial vehicles that come to Station.”
Burbank is a US astronaut and captured stunning images of Comet Lovejoy from the ISS just before Christmas, collected here.
Make or break time for NASA’s big bet on commercial space transportation is at last in view. NASA has announced Feb. 7, 2012 as the launch target date for the first attempt by SpaceX to dock the firms Dragon cargo resupply spacecraft to the International Space Station (ISS), pending final safety reviews.
The Feb. 7 flight will be the second of the so-called Commercial Orbital Transportation Services (COTS) demonstration flights to be conducted by Space Exploration Technologies, or SpaceX, under a contact with NASA.
Several months ago SpaceX had requested that the objectives of the next two COTS flights, known as COTS 2 and COTS 3, be merged into one very ambitious flight and allow the Dragon vehicle to actually dock at the ISS instead of only accomplishing a rendezvous test on the next flight and waiting until the third COTS flight to carry out the final docking attempt.
The Dragon will remain attached to the ISS for about one week and astronauts will unload the cargo. Then the spacecraft will depart, re-enter the Earth atmosphere splashdown in the Pacific Ocean off the coast of California.
“The cargo is hundreds of pounds of astronaut provisions,” SpaceX spokeswoman Kirstin Grantham told Universe Today.
“SpaceX has made incredible progress over the last several months preparing Dragon for its mission to the space station,” said William Gerstenmaier, NASA’s associate administrator for the Human Exploration and Operations Mission Directorate. “We look forward to a successful mission, which will open up a new era in commercial cargo delivery for this international orbiting laboratory.”
Since the forced retirement of NASA’s Space Shuttle following the final fight with orbiter Atlantis in July 2011 on the STS-135 mission, the US has had absolutely zero capability to launch either supplies or human crews to the massive orbiting complex, which is composed primarily of US components.
In a NASA statement, Gerstenmaier added, “There is still a significant amount of critical work to be completed before launch, but the teams have a sound plan to complete it and are prepared for unexpected challenges. As with all launches, we will adjust the launch date as needed to gain sufficient understanding of test and analysis results to ensure safety and mission success.”
SpaceX lofted the COTS 1 flight a year ago on Dec. 8, 2010 and became the first private company to successfully launch and return a spacecraft from Earth orbit. SpaceX assembled both the Falcon 9 booster rocket and the Dragon cargo vessel from US built components.
The new demonstration flight is now dubbed COTS 2/3. The objectives include Dragon safely demonstrating all COTS 2 operations in the vicinity of the ISS by conducting check out procedures and a series of rendezvous operations at a distance of approximately two miles and the ability to abort if necessary.
The European ATV and Japanese HTV cargo vessels carried out a similar series of tests during their respective first flights.
After accomplishing all the rendezvous tasks, Dragon will then receive approval to begin the COTS 3 activities, gradually approaching the ISS from below to within a few meters.
Specially trained astronauts working in the Cupola will then reach out and grapple Dragon with the Station’s robotic arm and then maneuver it carefully into place onto the Earth-facing side of the Harmony node. The operations are expected to take several hours.
If successful, the Feb. 7 SpaceX demonstration flight will become the first commercial mission to visit the ISS and vindicate the advocates of commercial space transportation who contend that allowing private companies to compete for contracts to provide cargo delivery services to the ISS will result in dramatically reduced costs and risks and increased efficiencies.
The new commercial paradigm would also thereby allow NASA to focus more of its scarce funds on research activities to come up with the next breakthroughs enabling bolder missions to deep space.
If the flight fails, then the future of the ISS could be in serious jeopardy in the medium to long term because there would not be sufficient alternative launch cargo capacity to maintain the research and living requirements for a full crew complement of six residents aboard the orbiting laboratory.
Feb. 7 represents nothing less than ‘High Stakes on the High Frontier’.
NASA is all about bold objectives in space exploration in both the manned and robotic arenas – and that’s perfectly represented by the agencies huge gamble with the commercial cargo and commercial crew initiatives.
Hailed as a both a great day for commercial spaceflight as well as for NASA, SpaceX made history on Wednesday with a 100% successful test flight of its Dragon capsule and Falcon 9 rocket. “This is a new way of doing business,” said Alan Lindenmoyer manager of NASA’s Commercial Crew and Cargo Program Office, “and I would say today this is an indication that this public/private partnership is working and has proven to be successful. Thanks to SpaceX for the early Christmas present – this is a great way to start the holidays.”
At the press conference following the flight, SpaceX CEO Elon Musk at first appeared to be speechless: “Really, this has been better than I expected,” he said. “It all went right. I am sort of in semi shock—I wish I could be more articulate in moments like this, bit it’s hard to be articulate with a blown mind!”
But Musk soon found his words – and lots of them (with many great quotes, so keep reading…)
Lindenmoyer said SpaceX’s accomplishments are quite an achievement, since over the last 20 years, for new launch vehicles only about 50% of them are success are successful on their first or second flights, and only 1 out of 3 new vehicles have two successful flights in a row, which SpaceX has achieved.
Musk said the success really shouldn’t be a surprise since the Dragon spacecraft has so many redundancies: 18 thruster engines instead of 9, 3 parachutes when they really could land with one, extra thermal protection, and a very advanced heat shield. But in the end, SpaceX didn’t need to use any of the backup systems.
Preliminary data said the Dragon reentered the atmosphere spot on at a 12% angle of attack, with 2% dispersion. “This is a testament to the incredible work of the people at SpaceX,” he said. “Everyone did their jobs so well.”
Musk also emphasize that his company couldn’t have gotten to where they are without NASA, in not only monetary support ($278 million for the COTS program), but in leading the way in spaceflight.
“The core concepts of Falcon 9 and Dragon were demonstrated decades ago by NASA, and its an old saying, but we are only here because we stand on the shoulders of giants. So thank you,” he said.
Musk noted a few key things about the flight: The restart of Falcon 9’s second stage went perfectly; the second stage as restarted after the release of Dragon, and rose to an altitude of more than 11,000 km (6,800 miles), Musk said. Secondary satellite payloads of nanosatellites were released during the flight. And, Musk added, that altitude was with the trimmed, repaired nozzle. Reaching an altitude that high was not part of SpaceX’s primary objectives, but nice to have, Musk said.
Dragon went to an altitude of 300 km.
Musk also stressed that the difference between this Dragon capsule and one that could carry people isn’t that different.
“People sometimes think the different between cargo and crew required enormous amount of magical pixie dust,” he said “This is not the case. If there would have been people sitting in Dragon today, they would have had a nice ride, feeling about 4-5 G’s, which is about what an amusement park ride is like,” with an 8 meter per second descent speed which is quite comfortable from a landing perspective.
The only differences, Musk said, would be the addition of a launch escape system. And, he revealed, what SpaceX really hopes to do with future spacecraft is not a splashdown in the ocean but a propulsive landing on the ground.
“The architecture you saw today was similar to what was employed in Apollo era, but we are aiming for propulsive landing with gear, kind of like the Eagle landing on the moon, and being able to take off again” he said. “Full reusability of Dragon and Falcon 9 is important as well, and something we want to figure out over time.”
Musk also said this mission didn’t have many significant differences in one that would send the Dragon the ISS. “In our discussions with NASA they said if this flight went well they would strongly consider letting us go to the space station on next mission,” he said. “I hope that is what NASA will allow us to do, we need to still examine the data from this mission first, but I’m highly optimistic. There are additional elements to be added to Dragon such as solar panels and redundancy on flight computers and electronics, but feel highly confident we could make it to the ISS on our next flight by middle of next year.”
Today’s flight tested the fundamentals of a heat shield and precision landing. Musk said the performance of heat shield was spectacular, and projected that is could not only handle Earth reentry, but also lunar and Mars reentry.
SpaceX president Gwynne Shotwell noted some other technical details, of how Dragon was able to maintain attitude and thermal control, as well as maintain communications with ground stations and TEDRIS satellites, which requires specific directional pointing.
The entire launch and two orbit flight took 3 hours 19 min 52 seconds, and initial data said they landed within 10 km of their target, and a communiqué from the Air force said Dragon came within 800 meters.
Asked about the flame flare that came about 2 seconds after launch, Musk said the first look by engineers said it was a check valve on the second stage umbilical that came off and caught fire as the spacecraft engines passed by — not an explosion but a just little fire.
Musk said the point in the flight where he felt the most jubilation and great relief was when the parachutes deployed. “Drogue and main chute deploy were riskiest parts, so when that happened, it was done deal. Just mind-blowingly awesome.”
Asked if the success today would silence any of SpaceX’s critics, Musk said, “I think if there really are people who are going still find a way to cast aversions on what we’ve done today, I pity them. It just wouldn’t make any sense.”
He said politicians who initially wanted to cut commercial crew funds from NASA’s budget soon learned that such a move would not decrease but increase the deficit and also meant increased time with no American access to space. “I think some politicians were initially mislead, but then they realized the value of commercial crew, which is why it the cuts didn’t make it into the final report.”
Asked about the differences in Dragon and NASA’s Orion spacecraft, Musk said that Space X would probably be the most rapid path to an American crew transport system. “If we would have had people on this flight we would have taken them to orbit and returned them safely,” he said. “Going to a crew system is just adding some additional safety systems for highly off nominal activities. Even for cargo missions we will be carrying plants and animals so I think we are in a very strong position to be one of the winners of the commercial crew contract.”
Musk added that competition is good, however, and NASA shouldn’t be too dependent on one company,” so hopefully there will be two or maybe three commercial crew providers and hopefully we are one of them.”
Musk agreed with Lindenmoyer on how this appears to vindicate the public/private model of space flight and shows that the commercial model works just as well in space flight as in air flight, or other arenas.
“The air mail program was a huge boost when the Post Office went commercial,” he said “and that resulted in explosion of innovation and improvement in technology. It really was the dawn of aviation in American where it went from joy rides that rich people could do, to today where aviation is accessible to almost everyone. I think historically COTS program will be seen in that light.”
On board Dragon was a few small satellites, and look for Musk to reveal tomorrow the nature of a humorous item that was on board. “I’m not going to reveal it today, as I don’t want some of the editors to use it in the first headlines,” he said. “It is kind of funny and if you like Monty Python you’ll like this one.”
Spam in a can?
Universe Today extends their congratulations to SpaceX. The future appears to be now.
