Originally scheduled for early November, SpaceX now plans to static fire a Crew Dragon capsule’s SuperDraco abort thrusters no earlier than Wednesday, November 13th. Success would pave the way for SpaceX to launch the spacecraft’s in-flight abort (IFA) before the end of 2019.

In April 2019, a bad design choice finally reared its head, triggering an oxidizer leak and exotic titanium chemical fire that lead to the catastrophic explosion of Crew Dragon capsule C201, the first upgraded spacecraft to successfully launch, dock with the ISS, and return to Earth. That explosion occurred shortly after a successful Draco maneuvering thruster test and just milliseconds before the planned ignition of C201’s eight SuperDraco abort thrusters.

SpaceX planned on reusing flight-proven Crew Dragon capsule C201 to complete its In-Flight Abort (IFA) test, in which the spacecraft will attempt to escape from Falcon 9 during Max Q, the most aerodynamically stressful period of launch. After C201’s premature demise, SpaceX was forced to reassign new Crew Dragon spacecraft already in production, and capsule C205 – previously assigned to Dragon’s Demo-2 astronaut launch debut – was delivered to SpaceX’s Florida launch facilities in early October.

C205 will now support SpaceX’s IFA test. However, prior to launch, SpaceX (or NASA, or both entities) want to ensure that the fixes and upgrades retroactively applied to Crew Dragon will prevent C201’s failure mode from reoccurring. This proof will come in the form of a static fire test identical to the one that caused C201’s explosion. Dragon capsule C205 will be loaded with liquid dinitrogen tetroxide (also known as NTO or N2O4) and monomethylhydrazine (MMH) fuel and fire its much smaller Draco maneuvering thrusters.

Lastly, C205 will ignite its eight SuperDraco abort thrusters – capable of producing more than 570 kN (128,000 lbf) of combined thrust – to conclude the static fire acceptance test. NASA and SpaceX will likely analyze the results together, while SpaceX will refurbish and refuel the spacecraft as expediently as possible. If everything goes as planned, Crew Dragon C205 will be integrated with its disposable trunk section and transported to Launch Complex 39A sometime in late-November or December.

In an impressive demonstration of SpaceX’s ability to work fast, the company managed to determine the cause of C201’s explosion, correct design flaws, prove those corrections with extensive testing, modify Crew Dragon C205 in light of those changes, and ship the completed spacecraft to Florida in less than six months. NASA Commercial Crew Program Manager Kathy Lueders, rare to heap praise, deemed SpaceX’s response “a pretty phenomenal turnaround.”

NASASpaceflight reporter Michael Baylor says that Crew Dragon’s static fire is now scheduled no earlier than the morning of November 13th, a delay of 11 days from the static fire’s first known target, November 2nd. It’s unclear what triggered the delay, but it would be unsurprising for SpaceX to be treading with extreme caution in a bid to avoid another serious Crew Dragon anomaly.

If all goes as planned during the test and the post-test inspections raise no red flags, SpaceX and NASA will likely be ready to launch Crew Dragon’s IFA test some 4-6 weeks after. Stay tuned for updates.

Tesla Roadster event gets delayed due to unfavorable weather

Published

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.

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.
