SpaceX’s Elon Musk teases in-house R&D for BFR refueling on Mars
SpaceX CEO Elon Musk took to Twitter to reaffirm SpaceX’s commitment to developing their own technology for refueling BFR beyond Earth, noting that the high-efficiency hardware would be “critical for propellant production at Mars Base Alpha.”
Known as in-situ resource utilization (ISRU), Musk briefly commented on SpaceX’s in-house work on the tech in an October 2017 Reddit AMA (Ask Me Anything), noting that “Design is pretty far along…it’s a key part of the whole system.” His most recent tweet on June 10 reiterated ISRU’s centrality to any successful (read: sustainable) colonization of Mars, and the CEO further confirmed what was already all but guaranteed, describing a chemical reaction known as the Sabatier process.
“SpaceX is already developing high-efficiency CO2 capture with H2O to form liquid CH4 (methane) & O2.” – Elon Musk, June 2018
At the most basic level, by combining heated, high-pressure carbon dioxide and hydrogen (easily derived from Mars’ CO2-rich atmosphere and wealth of water ice) and a bed of nickel or aluminum oxide, the Sabatier process can produce methane and water. Water can be easily decomposed into hydrogen and oxygen or used for drinking, cooking, and plumbing, among an infinite number of other uses. Akin to a more advanced version of what is already successfully utilized aboard the International Space Station, efficient Sabatier reactors can also be used to partially recycle wastewater and carbon dioxide (produced by humans breathing) to recover a significant fraction of pure water and methane.
In the case of SpaceX’s BFR rocket and spaceship, its propellant of choice will be liquid oxygen and methane (known as methalox) partly because of how comparatively easy it is to handle methane and to produce it on Mars, while simultaneously being a significant enabler of efficient long-term crewed spaceflight (i.e. the months-long deep space journeys to and from Mars). Less consumable mass required to keep passengers alive and happy directly translates into more payload to the surface of Mars, lowering the overall cost per kilogram delivered and thus the cost per ticket!

After landing on Mars, Sabatier reactors would be used to gradually refuel each Big F. Spaceship. Of course, the Sabatier process follows the laws of thermodynamics and thus requires a power source to heat the inputs, as well as cool the outputted methane and oxygen into fuel-grade cryo-cooled liquids. At least until SpaceX chooses to jump into the ring with the US nuclear (fissile) material regulation apparatus and develop or launch nuclear reactors, the most reliable power source for interplanetary colonization, that power will have to be supplied by acres upon acres of solar panels optimized to be as light, dense, and efficient as possible. If anything, the dust storm currently threatening the livelihood of Mars rover Opportunity should serve as evidence that solar power on Mars is at best a relatively cheap and simple stopgap for better power sources, especially for any long-term human presence on the Red Planet.
Optimally, BFS’ own internal solar array would (and likely will, at least at first) double as a source of power both in space and on the surface of Mars, neatly removing the need to waste precious cargo space on duplicate hardware. Even better, perhaps there is a chance that SpaceX’s materials scientists, engineers, and chemists can find ways to significantly optimize the Sabatier reaction for their specific needs, potentially lowering the energy required to get the desired end-product. It’s sort of a theme with interplanetary colonization, butttt… lower energy requirements translate to fewer solar panels needed to produce a given quantity of propellant in a set period of time, meaning that more payload can thus be dedicated to more important cargo like food, habitats, ISRU hardware, mining and tunneling machinery, and humans.
With any luck, followers of SpaceX may get an update on the company’s BFR plans later this year, likely just before or immediately after the first prototype spaceship is shipped to Texas for acceptance testing and a Grasshopper-style program of suborbital hops.

Tesla Full Self-Driving shows stunning maneuver in Europe to silence skeptics
In a striking demonstration of autonomous driving prowess, Tesla’s Full Self-Driving (FSD) system recently showcased its capabilities on the narrow rural roads of the Netherlands. Captured in two in-car videos, the system encountered scenarios that would challenge even the most experienced human drivers.
Tesla Full Self-Driving, fresh on the heels of its approval for operation on European roads for the first time, showed off a stunning maneuver that will certainly silence any skeptics on the continent.
Fresh off its approval in the Netherlands, Full Self-Driving is working toward a significant expansion into more parts of Europe.
In a striking demonstration of autonomous driving prowess, Tesla’s Full Self-Driving (FSD) system recently showcased its capabilities on the narrow rural roads of the Netherlands. Captured in two in-car videos, the system encountered scenarios that would challenge even the most experienced human drivers.
In the first clip, a wide tractor occupied more than half the lane on a tight two-way road. Rather than braking abruptly or forcing a collision risk, FSD smoothly edged the vehicle onto the adjacent bike path—using the extra space with precision—before seamlessly returning to the lane once clear.
The second clip was equally demanding: while overtaking a group of cyclists, an oncoming car approached at speed.
FSD maintained a safe, minimal buffer to the cyclists while timing the pass perfectly, avoiding any swerve or hesitation that could unsettle passengers or other road users.
People wonder if FSD is safe on narrow European roads. Well have a look what it did when a tractor took up more than half of the road or when overtaking bicycles with fast oncoming traffic. pic.twitter.com/z37Csa09sP

This maneuver highlights FSD’s advanced spatial reasoning and predictive planning. On roads often under three meters wide, with no room for error, the system calculated available clearance in real time, incorporated shoulder and path geometry, and executed a controlled deviation without compromising safety.
It treated the bike path as a legitimate extension of navigable space, something many drivers might hesitate to do, while respecting Dutch road norms and cyclist priority.
Such feats align closely with a growing library of impressive FSD maneuvers documented on camera worldwide.
In urban Amsterdam, for instance, FSD has navigated the world’s densest cyclist environments, weaving through hundreds of unpredictable bike movements on canal-side streets with tram tracks and pedestrians.
One uncut drive showed it yielding smoothly at crossings, overtaking where needed, and even handling a near-perfect auto-park in a tight residential spot, demonstrating the same low-speed precision seen in the rural clips.
Teslas using FSD have tackled turbo roundabouts in the Netherlands, complex multi-lane circles notorious for geometry challenges, merging confidently while yielding to traffic. Similar clips depict smooth handling of construction zones, emergency vehicle pull-overs, and gated parking barriers, where the car stops precisely, waits for clearance, and proceeds without driver input.
Collectively, these examples illustrate FSD’s evolution toward handling the unpredictable.
The rural Netherlands maneuvers aren’t isolated. Instead, they reflect a pattern of spatial awareness, cyclist deference, and traffic anticipation seen from city streets to highways.
As FSD continues refining through real-world data, videos like this one are certainly building a compelling case for its readiness on Europe’s varied roads.

Tesla utilizes its ‘Rave Cave’ for new awesome safety feature
Part of the massive interior overhaul of both the Model 3 “Highland” and Model Y “Juniper” was the addition of interior accent lighting to help bring out the mood of the vehicle, increase the customization of the interior, and to create a unique listening experience.
Tesla is utilizing its ‘Rave Cave’ for an awesome new safety feature that will arrive with the upcoming Spring Update for 2026.
Part of the massive interior overhaul of both the Model 3 “Highland” and Model Y “Juniper” was the addition of interior accent lighting to help bring out the mood of the vehicle, increase the customization of the interior, and to create a unique listening experience.
Tesla added a Sync Lights feature that will strobe the accent strips with the beat of the music.
It is one of the most unique and one of the coolest non-functional features of a Tesla, as it does not improve the driving of the vehicle, but makes it a cool and personal addition to the interior.
However, Tesla is going to take it one step further, as the Rave Cave lights will now be used for blind spot recognition. This feature will be added as the Spring 2026 Update starts to roll out.
A lot of CRAZY new features coming with Tesla’s 2026 Spring Update, including a new FSD app!

Tesla writes:
“Accent lights now turn red when an object is in your blind spot and your turn signal is engaged, or when an approaching object is detected while parked.”
This neat new safety feature will now increase the likelihood of a driver, who is operating their Tesla manually, of seeing the blind spot warnings that are currently available on the A pillar and on the center touchscreen.
These new alerts will now warn drivers of cross traffic as they back out of a parking space with little to no visibility of what is coming. It is a great new addition that will only increase the safety of the vehicles, while also utilizing something that is already installed in these specific Model 3 and Model Y units.
The Model 3 and Model Y were the central focus of the Spring 2026 Update, especially considering the fact that the Model S and Model X are basically gone, with only a few hundred units left. Additionally, Tesla included new Immersive Sound and Car Visualization for the Model 3 and Model Y specifically in this new update.

Tesla parked 50+ Cybercabs outside its Texas Factory with some crash tested
Dozens of Tesla Cybercabs have been spotted at Giga Texas crash testing facility ahead of launch.
Drone footage captured by longtime Giga Texas observer Joe Tegtmeyer shows over 50 units of Tesla Cybercab at the Austin factory campus, including several units clustered by Tesla’s on-site crash testing facility.
The outbound lot at Gigafactory Texas sits just outside the factory exit and serves as the primary staging area where finished vehicles are held before being loaded onto transport carriers or dispatched for validation testing. On any given day, the lot holds a mix of Model Y and Cybertruck units alongside the growing Tesla Cybercab fleet, as can be seen in the drone footage captured by Joe Tegtmeyer.
Roughly 50 Cybercab units are visible across the campus, parked in tight organized rows. Most of the units visible still carry steering wheels and pedals, temporary additions Tesla included to satisfy current safety regulations while the vehicles accumulate real-world data ahead of full regulatory approval for a steering wheel-free design. Tesla operates dedicated Crash Labs at both its Giga Texas and Fremont facilities that are purpose-built for controlled structural crash tests. Historically, automakers begin intensive crash testing roughly one to two months before volume production kicks off. The Cybertruck followed almost exactly that pattern. The Cybercab appears to be on the same track facility that we first saw back in October 2025. The first production Cybercab rolled off the Giga Texas line on February 17, 2026. Volume production is now targeted for April. Musk previously wrote on X that “the early production rate will be agonizingly slow, but eventually end up being insanely fast,” and separately stated Tesla is targeting at least 2 million Cybercab units per year. Commercial robotaxi service in Austin is targeted for late 2026.
