SpaceX tests extra-fast ocean landing, celebrates 50th launch

Published

The happy tragedy of 1044

SpaceX has successfully completed the 50th launch of Falcon 9 a bit less than eight years after its 2010 debut, and has done so in a fashion that almost perfectly captures the veritable tsunamis the company has begun to make throughout the global aerospace industry. After a duo of delays due to hardware issues and range conflicts, this evening’s launch successfully placed Hispasat 30W-6 into a geostationary transfer orbit (GTO), where the massive ~6100 kilogram communications satellite will now spend several months raising its orbit to around 36,000 km (22,000 miles) above Earth’s surface.

Aside from becoming the heaviest commsat the company has yet to launch into GTO, the mission’s anticipated landing attempt stirred up quite a bit of intrigue and uncertainty in the spaceflight fan community. Stormy Atlantic seas, partially connected to the chaotic weather recently seen on the East coast, proved to be far too dangerous for SpaceX’s eastern recovery fleet and its drone ship, OCISLY, and they returned to Port Canaveral around 48 hours ago, under the watchful eyes of many anxious SpaceX followers. Tragically, this means that the brand new Falcon 9 booster (B1044) – originally expected to attempt perhaps the most difficult landing yet – had to be expended. Although the booster went through its paces as if it were preparing to land, it found no drone ship beneath it once it reached sea level, and subsequently dunked into the stormy Atlantic seas.

However, due to the last-minute nature of SpaceX and Hispasat’s decision to expend the booster rather than delay for better recovery conditions, launch technicians at Pad 40 simply did not have time to remove the rocket’s iconic landing legs and valuable titanium grid fins – the first time their titanium iteration has been chosen for a Falcon 9 to resist extreme reentry heating. Due to massive swells, recovery of even pieces of the expended booster – theoretically following a soft landing – will not be possible, as no SpaceX recovery vessels remained at the planned point of touchdown 400 miles off the Florida coast. Notably, following the successful inaugural flight of Falcon Heavy, CEO Elon Musk stated that upgraded titanium grid fins were “super expensive” and unequivocally “the most important thing to recover.” SpaceX’s decision to expend Falcon 9 B1044 without even sparing the time to remove the booster’s recovery hardware and titanium fins demonstrates just how focused the company is on its customers’ needs. In the case of geostationary communications satellites like Hispasat 30W-6, launch delays on the order of a few days can cause millions of dollars of financial harm to the parent company – each day a satellite spends on the ground orbit is also a day with no revenue generation, a less-than-thrilling proposition to shareholders.

B1044 sadly lost any hope at a second flight, but the data SpaceX gathered from its uniquely fast reentry and attempted soft-landing will hopefully pave the way for the recovery of Falcon 9 and Heavy boosters after all but the heaviest satellite launches. GovSat-1, a launch that saw its flight-proven booster famously survive a similarly hot landing in the ocean, was the first largely successful test of this new and experimental method of more efficiently recovering Falcons. By igniting three of its nine Merlin 1D engines instead of the usual single engine while landing, Falcon boosters can theoretically reduce the amount of fuel needed to safely land, fuel savings that can then be used to push its payloads higher and faster. However, the downsides of this approach are several. With three times as many engines igniting at landing, the margin of error for a successful landing becomes downright miniscule – the tiniest of problems with ignition, throttle control, or guidance could cause the rocket to smash into the drone ship at considerable speed. Additionally, triple the landing thrust would subject the booster to as much as 10Gs of acceleration (10 times the force of Earth’s gravity), forces that would almost instantaneously cause the average human (and even specially trained fighter pilots) to black out.

Regardless of 1044’s untimely demise, another successful mission for SpaceX is purely positive. Happy customers make for a happy company, and SpaceX has achieved an incredible consistency of success in the last year alone. The loss of a new, potentially-reusable Falcon 9 booster is sad, but it only serves to foreshadow the imminent introduction of Falcon 9 Block 5, an upgrade hoped to realize Elon Musk’s decade-old dream of rockets that can be reused as many as 10 times with minimal refurbishment, and 100 times with maintenance. That debut could occur as early as April, just a month away.

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 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.
