SpaceX ramps South Texas activity to prepare for 2019 BFR spaceship testing

Published

on

At the same time as the hardware for SpaceX’s first BFR spaceship is entering the early stages of manufacturing, the company’s South Texas test facility is slowly taking shape after more than 18 months of what can be fairly described as hibernation.

The likeliest location for a near-future spaceship test stand or pad has also experienced a comparatively vast influx of construction workers and general activity that began earlier this month September, nearly two and half years after SpaceX began preparing the unstable coastal wetland with the addition of several hundred tons of soil.

It may not look like much, but ~5 contractors and a few pieces of heavy machinery truly is an explosion of SpaceX activity in South Texas. The hill in the background is the soil surcharging mound. (Maria Pointer, 09/19/2018)

According to a number of posts from local Texans that are also members of a small SpaceX fan group on Facebook, activity around the company’s Boca Chica, Texas facilities has exploded in recent months, and even more so over the last several weeks. SpaceX’s ground tracking facility has harbored the vast majority of attention for some time, particularly following the relatively recent arrival of a massive crane, construction of a shelter for said crane, and the appearance of two massive vacuum-insulated tanks for liquid oxygen (LOX) and liquid methane/natural gas (LNG).

Presently sat beside two large antennae on the Crew Dragon tracking facility’s plot, those propellant tanks are certainly both eye-catching and definitive evidence that something huge and nearby will soon need large quantities of liquid propellant. In the case of the LOX tank, a back-the-envelope estimate suggests that it can hold an obscene 400 metric tons (~900,000 lbs) of liquid oxygen, while the much smaller LNG tank (assumed, not guaranteed) would be capable of holding less than 25,000 kg of liquid methane, thanks mainly to the fact that liquid methane is roughly three times less dense than LOX.

Thankfully, SpaceX’s BFR Raptor engines will nominally burn oxygen and methane at a ratio of approximately 3.8 to 1, meaning that every 1 kg of methane exiting the rocket will be accompanied by 3.8 kg of oxygen. The fact that this ratio is actually larger than the density ratio of LOX and LNG means that the propellant tanks can be almost the same size

Most notably, as described above, is the abrupt return of construction and site preparation activities at what once was expected to be a Falcon 9 and Heavy launch pad. Over the last 24+ months, SpaceX has simply let the lot sit, although in this case, that sitting was rather productive. Known as soil surcharging, the site was essentially leveled, loaded with hundreds of tons of soil, plumbed with drainage pipes, and then left alone up to this point to let gravity do the rest of the work. Put simply, the unsteady soil of coastal Texas was aggressively drained and compacted into something stable enough to build expensive, long-term facilities on.

 

The hundreds of truckloads it took to bring in the soil will have to be repeated in reverse, removing most of the same soil to leave a level field ready for foundation-laying and series construction. Heavy machinery and construction contractors began arriving earlier this month, indicating that that process is about to begin, after which construction of the facilities that will eventually support Grasshopper-style spaceship testing can begin in earnest. Those BFR hop tests are scheduled to begin no earlier than late 2019.

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 moment

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

Published

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.
