NASA has shared new details on a test anomaly that resulted in the destruction of SpaceX’s Crew Dragon capsule last month.
In a briefing to the NASA Advisory Council, the space agency revealed it’s been in talks with SpaceX every day since the disaster as the two investigate what went wrong.
And, the latest information suggests the failure may not be as dire of a setback as it first appeared.
Documents shared on Twitter by NASA Spaceflight and NASA Watch reporters reveal SpaceX has other Dragon capsules in development that will be advanced to meet its planned demonstrations.
The update comes weeks after SpaceX finally confirmed that its crew capsule had been destroyed in the April 20 explosion.

SpaceX is already working to revise the schedules for the tests of its abort system and subsequent demonstration as the investigation into the anomaly continues.
‘SpaceX has multiple capsules in in build for the Dragon fleet and will advance assignments of capsules to specific missions,’ the document notes.
‘Capsule previously intended for Demo-2 will be used for IFA [in-flight abort] and the capsule intended for Crew-1 will be used for Demo-2, etc.
‘SpaceX is optimizing hardware configuration for each spacecraft based on intended use for those test flights.’
At the beginning of this month, officials involved the failed test of the Crew Dragon capsule confirmed for the first time that the vehicle was destroyed as the result of the yet-to-be-determined ‘anomaly.’
In a statement that aired on NASA TV, SpaceX Vice President of Mission Assurance Hans Koenigsmann said the investigation so far indicates that the failure occurred during activation of the SuperDraco propulsion system, though NASA and SpaceX are still ‘looking at all possible issues.’
The comments came amid mounting speculation in the weeks after the test, which sent plumes of dark orange smoke billowing into the air all around Florida’s Cape Canaveral launch site.

Ahead of the announcement, an internal email sent to employees of a major NASA contractor and obtained by the Orlando Sentinel appeared to finally confirm that the Crew Dragon capsule did, in fact, explode during the test.
‘Just keep in mind this is still very early in the investigating,’ Koenigsmann said, reading from a prepared statement.
‘The investigation is led by both SpaceX and NASA. Both teams are carefully reviewing the telemetry data and all of the data that was collected during that test.’
‘Priority of this moment is to allow the teams to conduct thorough analysis before we come to any conclusions,’ Koenigsmann added.
While NASA didn’t reveal much about the so-called anomaly itself, the space agency did note that the issue occurred during tests on the second set of thrusters, the SuperDraco system.
These thrusters will play a critical role in future launches with astronauts on board; they’re designed to safely steer the capsule away from the rocket in the case of an emergency.

The problems arose after a smooth static fire of the smaller Draco thrusters, which are also used on the original, cargo version of the Dragon capsule.
‘We powered up Dragon and it powered up as expected,’ Koenigsmann said.
‘We completed test with the Draco Thrusters. We fired them in two sets, each 4 to 5 seconds, and that went very well.
‘And then, just prior, before we went to fire the SuperDraco, there was an anomaly and the vehicle was destroyed.’
Koenigsmann confirmed there were no injuries, as previously reported, and noted that SpaceX had taken all of the proper safety measures ahead of the test.
It’s still ‘too early to determine any cause,’ he added, but said the investigation so far ‘indicates that the anomaly occurred during the activation of the Super Draco system.’
‘We are looking at all possible issues and the investigation is ongoing,’ Koenigsmann said.
‘We have no reason to believe that there is an issue with the SuperDraco themselves – those have been through about 600 tests at our test facility.
‘We continue to have high confidence in that particular thruster.’
An email sent to employees after the SpaceX footage leaked warned them not to record activity inside the Kennedy Space Center – if they do, they risk being fired
For nearly two weeks up until that point, both NASA and SpaceX have remained tight-lipped about the failed test, even as footage circulating the internet claimed to show the moment the Crew Dragon capsule exploded.
The leaked email sent to employees of the aerospace company Jacobs, who are working as contractors under NASA’s Test and Operations Support Contract, directly addressed the footage as it warned employees not to record activity inside the Kennedy Space Center – if they do, they risk being fired.
At the time of the initial incident, NASA said it’s too early to revise the target launch dates.
‘This is why we test,’ NASA Administrator Jim Bridenstine said in a statement the weekend of the test failure.
‘We will learn, make the necessary adjustments and safely move forward with our commercial crew program.’
WHAT IS SPACEX’ CREW DRAGON CAPSULE?

The capsule measures about 20 feet tall by 12 feet in diameter, and will carry up to 7 astronauts at a time.
The Crew Dragon features an advanced emergency escape system (which was tested earlier this year) to swiftly carry astronauts to safety if something were to go wrong, experiencing about the same G-forces as a ride at Disneyland.
It also has an Environmental Control and Life Support System (ECLSS) that provides a comfortable and safe environment for crew members.
Crew Dragon’s displays will provide real-time information on the state of the spacecraft’s capabilities, showing everything from Dragon’s position in space, to possible destinations, to the environment on board.
Those CRS-2 Dragon missions will use ‘propulsive’ landings, where the capsule lands on a landing pad using its SuperDraco thrusters rather than splashing down in the ocean.
That will allow NASA faster access to the cargo returned by those spacecraft, and also build up experience for propulsive landings of crewed Dragon spacecraft.
