Elon Musk and SpaceX won’t be stopped along the road to Mars

Published

If one is to take anything at all away from Elon Musk’s update to SpaceX’s planetary colonization strategy on September 29, it ought to be the tangible and undeniable progress the company has made with real, Mars-focused hardware development.

To take Musk at his word, the general atmosphere pervading the two relevant programs is one of extreme success and confidence. Raptor, the powerful methane-oxygen rocket engine intended to be the workhorse for any larger launch vehicle, has conducted dozens (42, to be specific) of successful hot fires at SpaceX’s McGregor, Texas testing facilities. These ranged from a handful of seconds all the way to 100 seconds in duration, and Musk made it explicitly clear that the only limiting factor to test duration was the size of the tanks of propellant available to fuel the engine. Of crucial importance is the fact that the engine being tested in Texas is a subscale prototype, and is not representative of the final engine. However, SpaceX has since shrunk the final target for operational Raptors, and this means that the current scale is not far off from the final thrust figure. The prototype Raptor is believed to have a thrust of approximately 1,000 kN (Kilonewtons), with slides from Musk’s 2017 presentation pointing to a full scale thrust of 1700 kN, far closer to becoming real than the 3,000 kN figure given at the 2016 IAC.

Possibly even more significant is the reported success SpaceX has had with the construction and stress testing of a full-scale carbon fiber liquid oxygen tank, which was tested to a very eventful destruction on Washington state’s Puget Sound. Fans closely followed this series of tests, but information was scarce and the general consensus was that the tank had failed unintentionally during those tests. The fact that Musk claimed that the 12 meter diameter tank was “successfully tested” at high pressures, as well as the confidence he expressed about a uniquely capable “carbon fiber matrix”, suggest that SpaceX have leaped over one of biggest potential hurdles of their larger vehicle plans. Carbon fiber propellant tanks have the potential to make rockets significantly lighter and thus more efficient, particularly if no internal liner of metal is needed to ensure the safety of those carbon fiber tanks. One might remember the difficulties SpaceX had with supercool liquid oxygen, culminating in the Amos-6 mishap that saw carbon fiber helium tanks clash with SpaceX’s then-new supercooled propellant procedures.

Through many challenging mistakes, SpaceX has learned the hard way that extra care must be taken when mixing carbon fiber and liquid oxygen. The telltale sign that SpaceX has, however, successfully learned from those mistakes can be found in the company’s aspiration to begin construction of the first BFR cargo ship as early as April of 2018, barely six months from today. Time will tell if they can maintain that aggressive schedule and launch two Mars-bound cargo ships in 2022. The company’s incontrovertible success with the development of Raptor engines and carbon fiber propellant tanks bode extremely well for the future of their planetary colonization efforts.

Tesla Roadster event gets delayed due to unfavorable weather

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 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.
