Six weeks after the spacecraft completed its orbital launch debut, SpaceX’s first flight-proven Crew Dragon capsule suffered a catastrophic explosion seconds before a planned SuperDraco test fire.

In the last nine years, SpaceX has successfully built, tested, launched, and recovered Cargo and Crew Dragons 18 times, including five instances of Cargo Dragon capsule reuse, all with minor or no issues. The April 20th event is the first time in the known history of SpaceX’s orbital spacecraft program that a vehicle – in this case, the first completed and flight-proven Crew Dragon capsule – has suffered a total failure. Regardless of the accident investigation’s ultimate conclusions, the road ahead of Crew Dragon’s first crewed test flight has become far more arduous.

According to information acquired by NASASpaceflight.com, SpaceX was in the middle of a series of static fire tests meant to verify that the flight-proven capsule was in good working order after Crew Dragon’s inaugural mission to orbit. The spacecraft was to be tested near SpaceX’s Cape Canaveral Landing Zone facilities, where the company has a small but dedicated space for Dragon tests. Crew Dragon C201’s testing began earlier on Saturday, successfully firing up its smaller Draco maneuvering thrusters. This transitioned into a planned SuperDraco ignition, what would have been the first such integrated test fire for capsule C201.

SpaceX planned to rapidly reuse Crew Dragon C201 for an upcoming in-flight abort (IFA) test, in which the spacecraft would be required to successfully escape from Falcon 9 at the point of peak aerodynamic stress (Max Q). Based on a leaked video of the failure, one or several faults in Crew Dragon’s design and/or build led to a near-instantaneous explosion that destroyed the spacecraft. Sound in the background seems to indicate that the explosion occurred several seconds before the planned SuperDraco ignition, a major concern given their pressure-fed design.

As pressure-fed rocket engines specifically designed to be the basis of a launch escape system, Crew Dragon and its SuperDraco thrusters are meant to be ready to ignite at a millisecond’s notice once they are armed in a flight-ready configuration. It’s safe to say that ten seconds away from a specifically planned ignition is one of those moments, although there is a limited chance that SpaceX’s static fire procedures intentionally diverge from an abort-triggered ignition. Regardless, the fact that Crew Dragon was destroyed before the ignition of its SuperDracos is not an encouraging sign.

Instead of a problem with its high-performance abort thrusters, it can be tentatively concluded that Crew Dragon’s explosion originated in its fuel tanks or propellant plumbing. Such an immediate and energetic explosion points more towards a total failure of propellant lines or valves (or their avionics), while another – and potentially far more concerning – cause could be one of Crew Dragon’s pressure vessels. In a space as enclosed as a Dragon capsule, the rupture of a pressure vessel could trigger a chain reaction of pressure vessel failures, freeing both oxidizer (NTO) and fuel (MMH). Known as hypergolic propellant, NTO and MMH ignite immediately (and violently so) when mixed.

It’s quite possible that the accident investigation to follow will be SpaceX’s most difficult and trying yet. Regardless of the specific cause, the footage of Crew Dragon C201’s demise does not support any positive conclusions about the fate of astronauts or passengers, had they been aboard during the violent explosion. Seemingly triggered in some way by the very system meant to safely extricate Crew Dragon and its astronauts from a failing Falcon 9 rocket, major work will need to be done to prove to NASA that the spacecraft is safe. Sadly, Boeing’s Starliner spacecraft – funded in parallel with Crew Dragon under NASA’s Commercial Crew Program – suffered a far less severe but no less significant failure during a static fire test of its own abort thrusters. Boeing was forced to remove the impacted hardware from its flight plans to extensively clean, repair, and rework the service module.

NASA is now faced with the fact that both of the spacecraft it supported with CCP have exhibited major failures related to their launch escape systems. Crew Dragon’s catastrophic explosion comes as a particularly extreme surprise given how extensively SpaceX has already tested the SuperDraco engines and plumbing, as well as the successful completion of the spacecraft’s launch debut. In the process of DM-1 launch preparations, Crew Dragon likely spent a minimum of 80 minutes with its SuperDraco thrusters and propellant systems primed and ready to abort at any second, apparently without a single mildly-concerning issue.

Godspeed to SpaceX and NASA as they enter into this challenging and unplanned failure investigation.

Tesla Roadster event gets delayed due to unfavorable weather

Published

Credit: Tesla

Tesla is delaying its event for the Roadster, moving it from this Thursday, October 1, to Thursday, October 15, due to unfavorable weather.

The company has said it has been tracking the weather for this Thursday closely with local meteorologists, and because the event can only be held outside, Tesla is making the call to delay it:

“We’ve been tracking the weather closely with local meteorologists, but given the severe conditions predicted & because this event can only be held outdoors, we’ve made the difficult decision to reschedule. New date is October 15. Additional details to follow.”

We are sure that this is bringing back PTSD for some Tesla fans, and we know it is not ideal, but this also reveals some things about the event. Tesla said that this can only be held outdoors, meaning it bodes well for the rumors that the vehicle could potentially hover.

Some believe that this was essentially confirmed by the FAA airspace restriction they were granted, but this could have been for a drone show or to keep drones from spying on the event.

Tesla Roadster is available for order once again following brief hold

The Roadster event has been long-awaited, and it is unfortunate that the weather is going to keep us all waiting a little bit longer.

The Tesla Roadster will be unveiled in Waco, Texas.

SpaceX turned a heralding moment for Starship into its greatest

Starship reached orbit despite losing an engine, deployed 26 Starlink V3 satellites on Flight 14.

SpaceX’s Starship reached orbit for the first time on Monday, and for a few nail-biting minutes it looked like it wouldn’t. During ascent on Flight 14, one of Ship 41’s six Raptor engines shut down early, and SpaceX’s livestream host Dan Huot told viewers the team had decided not to commit to orbit. Minutes later, after what Huot described as a lot of conversation in the control room, the final poll came back in favor, and a roughly 19 second burn of a single Raptor pushed the ship into orbit about 170 miles up.

The reversal matters because SpaceX had written the exit ramp into the mission plan. The company said it would only fire the orbital insertion burn if flight controllers confirmed enough backup hardware remained for the deorbit burn, a condition Teslarati laid out ahead of the flight. Losing an engine was exactly the scenario that rule was built for.

Pressing forward fits Elon Musk’s history. Falcon 1 failed three straight times before its fourth launch reached orbit in 2008, with SpaceX nearly out of money, and Starship was developed by flying prototypes until they broke. What changed this year SpaceX going public, and with $SPCX sliding below its IPO price in July when Flight 13 slipped, the short interest climbed significantly, as Teslarati reported at the time. A Starship potentially lost today with revenue generating next-gen Starlink satellites aboard would have landed directly on shareholders.

That pressure showed up after orbit. SpaceX cut a flight planned to last nearly 10 hours to about three, moving splashdown from west of Chile to the North Pacific near Hawaii. SpaceX gave no reason, though Musk said this month the company was being extremely cautious about debris risk. The single Raptor for deorbit worked, and Ship 41 completed its flip and landing burn before breaking apart in the water, an outcome SpaceX expected. Musk has structured SpaceX’s governance to shield long term bets from market pressure.

The payload is the bigger business story. Musk posted that all 26 Starlink V3 satellites deployed and are “operating nominally.” Each V3 is rated for about 1 Tbps of downlink and 160 Gbps of uplink, so this single launch adds roughly 26 Tbps, about 10 times what a Falcon 9 load of V2 Mini satellites adds. The V3 is too large for Falcon 9, making Starship the only vehicle that can build out the planned 100,000 satellite constellation, at up to 60 per flight once it reaches routine service. Unlike the 20 V3 units on Flight 13, which reentered on a suborbital path, these will raise their orbits and could begin serving customers within weeks and bring in hundreds of millions of additional dollars in projected Starlink revenue.

SpaceX has already begun winding down Falcon 9 Starlink launches from Florida in favor of Starship. Reported targets put Flight 15 as early as October 19, leaving about three weeks to diagnose Monday’s engine shutdown before the next orbital attempt.

Tesla Cybercab fleet doubles to well over 100 units

Tesla quietly doubled the size of its Cybercab fleet within the Robotaxi program in Austin, Texas, over the weekend to well over 100 units.

The move not only establishes more of the steering-wheel-less and pedal-less vehicles within the ride-sharing fleet Tesla has been operating for a year, but it also solidifies a more robust Robotaxi fleet as a whole.

Riders started receiving notifications from the Robotaxi app that stated: “Cybercab fleet has doubled: more rides available.”

Tesla first launched rides in the Cybercab in early September, although the Robotaxi fleet has been active for over a year, as rides began last Summer. Cybercab is truly Tesla’s most crucial vehicle release yet, as it is the first car any company has built that is geared toward full-fledged and end-to-end autonomy, never needing human intervention for anything.

Only available in Austin at the current time, Cybercab has two seats and has been spotted testing around various U.S. states and regions; Tesla plans to deploy the Cybercab in various U.S. cities in the coming months as a best-case scenario.

Tesla Cybercab gets initial tie-in to localized, in-house cathode plant

The availability of the Cybercab has doubled from just 58 units last Monday to 125 the following Friday. Marking a substantial increase in Cybercab availability, the additional ride-sharing units are more than welcome, as wait times for Cybercabs, especially, were quite high.

The dramatic increase is a sign that demand for Robotaxi is growing and Tesla is feeling more confident that its driverless ride-hailing suite, especially its Full Self-Driving software, is able to handle any traffic situation without explicit direction or supervision from a human being.
