Possibly. “Right now we’re paying very close attention to the work that’s being done, coming out of the anomaly investigation, along with the other tests.” She said that Behnken and Hurley had been briefed “multiple times” on the investigation during their regular visits to SpaceX. “While it is too early to confirm any cause, whether probable or crude, the initial data indicates that the anomaly occurred during the activation of the SuperDraco [engine] system,” Koenigsmann told the press conference. "These changes, along with thorough testing and analysis will be completed "well in advance of future flights," according to SpaceX. Neither Koenigsmann nor Lueders would commit to a schedule for resuming test flights of the Crew Dragon spacecraft, including both the in-flight abort and the Demo-2 mission, which will carry NASA astronaut Bob Behnken and Doug Hurley. The company has been searching for the cause of a catastrophic explosion that destroyed an unmanned Crew Dragon spacecraft in April “We had the ability to find an issue with the hardware and be able to find the hardware and be able to assess the hardware,” she said. When the system was pressurized just before the planned ignition, a “slug” of NTO was driven at high speed into a titanium check valve, causing structural failure of the valve and igniting it, triggering the explosion. All rights reserved. The “safety and performance” of the manned vessel are of “particular concern” to Nasa as well as SpaceX, says The Verge. “I hope this a relatively swift investigation at the end of the day, and I don’t want to completely preclude the current schedule,” Koenigsmann said at a press conference. “I feel like this is actually the better component.”, Kathy Lueders, manager of NASA’s commercial crew program, called the accident a “huge gift” for the agency, and for SpaceX, since it discovered the flaw in a ground test.

"SpaceX also eliminated any flow path within the launch escape system for liquid propellant to enter the gaseous pressurization system," a statement from the company said. A slug of this (nitrogen tetroxide) was driven through a helium check valve at high speed during rapid initialization of the launch escape system, resulting in structural failure within the check valve. SpaceX had planned to use the Crew Dragon to send two astronauts to the ISS as early as July, but the test failure puts the mission “in serious doubt”, says Space.com. US election 2020 polls: who is going to win - Donald Trump or Joe Biden? According to SpaceX, all the Draco thrusters were tested successfully but, about a tenth of a second before the scheduled ignition of the SuperDraco thusters, the anomaly took place that destroyed the spacecraft. Crew Dragon Explosion. ", "The reaction between titanium and nitrogen tetroxide at high pressure was not expected," SpaceX said in a statement, because "titanium has been used safely over many decades and on many spacecraft from all around the world.".

“We have no reason to believe there is an issue with the SuperDracos themselves,” Koenigsmann insisted.

Prior to the accident the Demo-2 mission was officially scheduled for late summer, but most industry observers expected it to slip to late in the year. Koenigsmann said work like replacing check valves with burst disks can be done at the same time as other activities that need to be completed prior to NASA’s approval for the Demo-2 flight, like completing testing of parachutes.

SpaceX said the most likely cause of the explosion was when a “leaking component” allowed nitrogen tetroxide (NTO) oxidizer into helium tubes during processing. He said SpaceX, with the assistance of NASA, confirmed this scenario in testing at the company’s McGregor, Texas, test site.

Not a very helpful answer, but we don’t know at this point and it will likely be at least a few weeks before we hear anything beyond the preliminary statements already given. She also praised SpaceX for its work on the investigation, and that now was the time to “be transparent” about the status of the investigation. NASA’s Commercial Crew Program Manager Kathy Lueders said NASA still has not determined what this means for when SpaceX can begin launching astronauts. The grainy footage, filmed at at Florida’s Cape Canaveral launch site, was posted by YouTube channel rocket.watch. SpaceX had already started production of other Crew Dragons before the explosion, The Verge reports. What caused SpaceX’s Crew Dragon explosion. “There’s always a chance we’re going to fly crew on a SpaceX vehicle this year,” Lueders said. The check valves, which can leak, will be replaced with burst disks that remain sealed until they reach a certain pressure. “While it is too early to confirm any cause, whether probable or crude, the initial data indicates that the anomaly occurred during the activation of the SuperDraco [engine] system,” Koenigsmann told the press conference, CNBC reports. Prior to the testing mishap, the same Crew Dragon capsule successfully launched from Kennedy Space Center on a Falcon 9 rocket, docked at the space station’s new international docking adapter and splashed down in the Atlantic Ocean after a six-day stay. The failure of the titanium component in a high-pressure NTO environment was sufficient to cause ignition of the check valve and led to an explosion. SpaceX which is in process of certifying its spacecraft to fly NASA astronauts as part of the commercial crew program. Explore the best of the media in one magazine. Koenigsmann said the static fire test and anomaly provided a wealth of data and will lead to further improvements in the safety and reliability of SpaceX’s flight vehicles. Emilee is a digital journalist for News 6 and ClickOrlando.com, where she writes about space and Central Florida news.

He said that just prior to the loss of the capsule, the company had “completed tests” of the thrusters, adding: “We fired them in two sets, each for five seconds, and that went very well.”. During which SpaceX will launch a Falcon 9 with the spacecraft then cause a problem to trigger the capsule to be safely jettisoned away from the rocket.
