SpaceX begins huge dirt pile removal to pave way for BFR spaceship hop tests
After more than two years of silence, SpaceX has taken the first major tangible steps towards the construction of a dedicated South Texas rocket testing facility.
In anticipation of a full-scale BFR spaceship (BFS) hop test campaign that could begin as early as late 2019, local contractors and a smattering of SpaceX employees have begun to earnestly break down and repurpose a large quantity of dirt – known as a surcharge pile – to allow the construction of real facilities to begin.
Documented as of late by a handful of interested local observers and another subset of less local but equally interested followers, SpaceX’s prospective South Texas test and launch facilities have experienced a near-unprecedented burst of activity over the last two months, most notably including the arrival of a small fleet of heavy machinery and construction contractors at a site SpaceX has been working on for three years.
After ~36 months of dead silence, this activity correlates well with recent comments from SpaceX executives Elon Musk and Gwynne Shotwell indicating that the company is still targeting inaugural BFR spaceship hop tests sometime near the end of 2019.

The infrastructure needed for those early tests could be quite sparse depending on the status of the BFR hardware to be ‘hopped’ – Falcon 9’s Grasshopper and F9R test campaigns, for example, operated off of a tiny concrete pad with extremely minimalist ground support equipment (GSE). Photos from a number of videos SpaceX posted during those crafts’ 2012-2014 series of hop tests demonstrate this minimum well, although chances are good that the company will build up Boca Chica a bit beyond the test pad used for Falcon 9 booster recovery R&D.

SpaceX’s Grasshopper and F9R hop tests took place exclusively at the company’s well-established McGregor, Texas testing facilities, offering a range of large hangars, three operational Merlin 1D and Vacuum test bays, and dedicated stands for integrated first and second stage static-fire tests, among countless other rocketry-related amenities. The secluded South Texas coastal region where SpaceX wants to test – if not launch – integrated BFRs has none of McGregor’s preexisting infrastructure, however – anything SpaceX needs will have to be built from scratch on-site.

Thus far, almost no real structures have been constructed, aside from a small-ish sheet metal shed that was literally built around a huge crane that arrived on SpaceX property a few months prior. Over the last two or so years, all activity at the South Texas site clustered specifically around a plot where two large radio dishes – and eventually cryogenic storage tanks – were delivered, installed, and/or stored. However, the actual site of the pad SpaceX originally planned to launch Falcon 9 and Heavy from is a mile or two East of that highly visible development, the same location where a flurry of activity has begun in the last month.

In 2015, SpaceX trucked in several hundred thousand tons of dirt to be packed on top of the site where the company eventually planned to build a large Falcon integration hangar and then left for several years to crush the softer marshlands beneath it into firm submission. That time appears to be up, as the work now ongoing at that site is focused on removing that surcharging dirt now that the soil beneath it is stable enough to host heavy, long-term structures like a rocket launch pad.
Most of that massive dirt pile will likely remain at SpaceX’s South Texas property, to be used as a basic construction material as the company begins to build some semblance of the facility described in its approved 2014 environmental impact assessment. As it takes shape, it will become clear just how closely SpaceX is sticking to those original plans. BFR hop tests could begin by late 2019 if prototype spaceship construction – already in work at a tent in Port of Los Angeles – proceeds smoothly.

A Tesla Semi caught fire in Hayward, California, which caused both directions of traffic to shut down for hours before being completely reopened early on Wednesday, the California Highway Patrol said.
The fire occurred just after 5:30 local time in Hayward on Tuesday, as the Semi caught fire in the southbound lanes of I-880 before CHP officials made the decision to shut down both lanes of traffic due to potential risks from hazardous chemical smoke.
There were no injuries reported.

The cause of the fire is currently unknown, as neither Tesla nor the CHP have not determined a cause.
However, some images taken before the Semi was completely destroyed by the fire seem to indicate this might have been an older unit, as it appears to be one of the designs that Tesla shipped as part of its pilot program, before revising it and starting mass production just a month ago.
@Tslachan From on of the videos looks like it’s an old Semi (not the refresh version that recently started production) https://t.co/KzwmR2kXow

At the time of publication, CHP had not returned our request for a comment for additional details, including the Semi involved and any potential collaboration on an investigation between the CHP and Tesla. We will update this story when we hear back from them.
The southbound lanes were reopened at 3:30 a.m. on Wednesday, with the northbound lanes opening last night a few hours after the fire began. The CHP did state that the lithium batteries were “incredibly difficult to extinguish,” according to NBC Bay Area.
The truck’s driver said that the Semi caught fire, but he did not have an explanation.

Tesla’s launch of the “Emergency Drive Away” function a few months back offered owners a safe option to evacuate an area if they were in reasonable danger. The function finally got its first use in the real world, but it appears it was by mistake.
A video shared by u/Joshalander in the r/TeslaLounge subreddit recorded the instance from his vehicle and said the incident took place in Austin this past weekend during the city’s F1 Race.
“Was charging around 6 AM this past Sunday in Austin before heading to the F1 race and heard a pop. Looked over and saw the new emergency drive-away feature in action. Genuinely felt bad for the dude when he got out and realized what happened, since he looked exhausted and only seemed to half-read the prompts.”
🚨 Here’s the first look at Tesla’s Emergency Drive Away function in action:
Apparently this driver accidentally enabled it and drove forward; you can see the Supercharger pull with the car.
Tesla said previously this would cost up to $25k if not used properly. https://t.co/B4qQRrsO6B

Emergency Drive Away unlatches the Supercharger connector from the vehicle, but still causes damage to both the car and the Supercharger. Tesla has said that it will cost up to $25,000 in repairs to have everything fixed back to normal.
Additionally, the company said that if it were not used in an emergency situation, the driver of the vehicle who activated the Emergency Drive Away feature would be responsible for all repair costs.
Tesla constitutes the following situations as reasonable justifications for activating the feature:
- You face an immediate threat to your life or personal safety.
- You must leave the area immediately.
- Exiting the vehicle is unsafe.
- Unplugging the charge connector would unreasonably delay your departure or expose you to a risk to your personal safety.
After using the feature, Tesla requires the driver to schedule Service so the car can be inspected.

Tesla’s Cybercab battery design could make robotaxis even cheaper
Tesla built the Cybercab’s battery pack with spare room for a future switch to LFP.
Tesla built the Cybercab’s battery pack with empty space inside it on purpose, and the reason points to a cheaper robotaxi down the road.
Robert Sumpf, Tesla’s director of mechanical design engineering for battery modules and packs, said the extra room beside and beneath the Cybercab’s modules was left there so the company can move to lithium iron phosphate cells later. “So, we protected this pack to go to an even lower energy dense chemistry as we scale and need to bring LFP into the platform,” Sumpf said in a Cybercab deep dive with Munro Live.
The Cybercab runs on Tesla’s own 4680 cells with a nickel chemistry today. LFP cells store less energy for their size, so a straight swap would cut range. The reserved space lets Tesla add more LFP cells to make up the difference. In return, Tesla would get cells that cost less, run cooler and survive more charge cycles. LFP became the most used EV battery chemistry in the world last year.
Not all of that room was planned for a chemistry change. Lars Moravy, Tesla’s Vice President of Vehicle Engineering, said part of it exists because “we didn’t need as many batteries as we thought we did.” Tesla told Sandy Munro in early 2025 that it was targeting a Cybercab pack under 50 kWh with close to 300 miles of range.
The pack also breaks from the structural design Tesla used in some Model Y and Cybertruck builds. Instead of potting hundreds of cells into one block, the Cybercab uses four separate, individually sealed modules, so a bad module can be replaced without scrapping the whole pack. Sumpf was blunt about the older approach, giving the Model Y structural battery “a grade D” because it was hard to build and nearly impossible to repair. He estimated a fully structural pack gains about 10% more cell volume, but said “the issue is the service cost.”
That cost matters more for a car that rarely sits parked. Cybercab chief engineer Eric Earley said replacing an entire pack “before half a million miles is a killer on cost,” which is why remanufacturing and serviceability were built into the design from the start.
The same Munro Live tour produced Moravy’s admission that the Cybercab line at Giga Texas is now outpacing Robotaxi deployments, along with a look at the robotaxi’s unorthodox paint process. Tesla is aiming to deliver the first Cybercabs to outside customers by the end of 2026, though Elon Musk has said the vast majority will stay owned by Tesla and run as a transport service.
Sumpf did not give a date for an LFP version, name a cell supplier or say how a chemistry change would affect range. For now, the 4680 cars keep piling up: Texas DMV records from Tuesday list 544 Cybercabs authorized for Tesla’s Robotaxi fleet, more than the 507 Model Ys on the same roster for the first time.
