NASA funds study on SpaceX BFR as option for massive space telescope launch
Speaking at the Exoplanets II conference in Cambridge, UK July 6th, geophysicist and exoplanet hunter Dr. Debra Fischer briefly revealed that NASA had funded a study that would examine SpaceX’s next-gen BFR rocket as an option for launching LUVOIR, a massive space telescope expected to take the reigns of exoplanet research in the 2030s.
Conceptualized to follow in the footsteps of NASA’s current space telescope expertise and (hopefully) to learn from the many various mistakes made by their contractors, the LUVOIR (shorthand for Large UV/Optical/IR Surveyor) concept is currently grouped into two different categories, A and B. A is a full-scale, uncompromised telescope with an unfathomably vast 15-meter primary mirror and a sunshade with an area anywhere from 5000 to 20000 square meters (1-4 acres). B is a comparatively watered-down take on the broadband surveyor telescope, with a much smaller 8-meter primary mirror, likely accompanied by a similarly reduced sunshade (and price tag, presumably).

Remember, this is a space telescope that would need to fit into the payload fairing of a rocket, survive the launch into orbit, and then journey nearly one million miles from Earth to its final operational destination, all before deploying a mirror and starshade as large or larger than Mr Steven’s SpaceX fairing recovery net. The James Webb Space Telescope (JWST), a rough successor to Hubble with a 6.5-meter primary mirror, is the only space telescope even remotely comparable to LUVOIR, and it has yet to launch after suffering a full decade of delays and almost inconceivable budget overruns. All we can do is hope that Northrop Grumman (primary contractor for JWST) is kept away from future giant space telescopes like LUVOIR.

The rocket problem
Nevertheless, the sheer scale of LUVOIR brings us back to an existential problem faced by all space telescopes – how to get into space in the first place. In this case, JWST offers a small taste of what launching such a large telescope requires, although it only truly applies the 8m LUVOIR B. The reason LUVOIR’s conceptual design was split into two sizes is specifically tied to the question of launch, with LUVOIR B’s 8m size cap dictated by the ~5 meter-diameter payload fairings prevalent and readily available in today’s launch industry.

LUVOIR A’s 15-meter mirror, however, would require an equally massive payload fairing. At least at the start, LUVOIR A was conceptualized with NASA’s Space Launch System (SLS) Block 2 as the launch vehicle, a similarly conceptual vehicle baselined with a truly massive 8.4 or 10-meter diameter payload fairing, much larger than anything flown to this day. However, the utterly unimpressive schedule performance of the SLS Block 1 development – let alone Block 1B or 2 – has undoubtedly sown more than a little doubt over the expectation of its availability for launching LUVOIR and other huge spacecraft. As a result, NASA has reportedly funded the exploration of alternative launch vehicles for the A version of LUVOIR – SpaceX’s Cargo BFR variant, in this case.
While only a maximum of 9 meters in diameter, the baselined cargo spaceship’s (BFS Cargo) payload bay has been estimated to have a usable volume of approximately 1500 cubic meters, comparing favorably to SLS’ 8.4 and 10-meter fairings with ~1000 to ~1700 cubic meters. The more traditional SLS fairing may offer more flexibility for minimizing complex deployment mechanisms for large telescopes (a sore spot for JWST), but SLS Block 2 is almost entirely up in the air at the moment, and liable to cost $5-10 billion alone to develop even after SLS Block 1 is flying (NET mid-2020). On the other hand, barring abject and total failure, SpaceX’s BFR rocket and spaceship could have many, many launches under its belt and a proven track record of reliability, whereas SLS Block 2 is unlikely to fly more than a handful of times ever, even if it gets built.

With any luck, the results of the LUVOIR SpaceX BFR launch analysis will make their way into the public sphere once the study is completed, perhaps revealing a few tidbits about the capabilities of the next-generation composite rocket. Another astrophysicist familiar with the project also noted that Blue Origin was firmly in the running of similar conceptual launch studies, hinting at a potential competition for commercial launches of each company’s massive future rockets.

Tesla Cybercab spotted with interesting charging solution, stimulating discussion
The port is located in the rear of the vehicle and features a manual door and latch for plug-in, and the video shows an employee connecting to a Tesla Supercharger.
Tesla Cybercab units are being tested publicly on roads throughout various areas of the United States, and a recent sighting of the vehicle’s charging port has certainly stimulated some discussions throughout the community.
The Cybercab is geared toward being a fully-autonomous vehicle, void of a steering wheel or pedals, only operating with the use of the Full Self-Driving suite. Everything from the driving itself to the charging to the cleaning is intended to be operated autonomously.
But a recent sighting of the vehicle has incited some speculation as to whether the vehicle might have some manual features, which would make sense, but let’s take a look:
🚨 Tesla Cybercab charging port is in the rear of the vehicle!
Here’s a great look at plugging it in!!

The port is located in the rear of the vehicle and features a manual door and latch for plug-in, and the video shows an employee connecting to a Tesla Supercharger.
Now, it is important to remember these are prototype vehicles, and not the final product. Additionally, Tesla has said it plans to introduce wireless induction charging in the future, but it is not currently available, so these units need to have some ability to charge.
However, there are some arguments for a charging system like this, especially as the operation of the Cybercab begins after production starts, which is scheduled for April.
Wireless for Operation, Wired for Downtime
It seems ideal to use induction charging when the Cybercab is in operation. As it is for most Tesla owners taking roadtrips, Supercharging stops are only a few minutes long for the most part.
The Cybercab would benefit from more frequent Supercharging stops in between rides while it is operating a ride-sharing program.
Tesla wireless charging patent revealed ahead of Robotaxi unveiling event
However, when the vehicle rolls back to its hub for cleaning and maintenance, standard charging, where it is plugged into a charger of some kind, seems more ideal.
In the 45-minutes that the car is being cleaned and is having maintenance, it could be fully charged and ready for another full shift of rides, grabbing a few miles of range with induction charging when it’s out and about.
Induction Charging Challenges
Induction charging is still something that presents many challenges for companies that use it for anything, including things as trivial as charging cell phones.
While it is convenient, a lot of the charge is lost during heat transfer, which is something that is common with wireless charging solutions. Even in Teslas, the wireless charging mat present in its vehicles has been a common complaint among owners, so much so that the company recently included a feature to turn them off.
Production Timing and Potential Challenges
With Tesla planning to begin Cybercab production in April, the real challenge with the induction charging is whether the company can develop an effective wireless apparatus in that short time frame.
It has been in development for several years, but solving the issue with heat and energy loss is something that is not an easy task.
In the short-term, Tesla could utilize this port for normal Supercharging operation on the Cybercab. Eventually, it could be phased out as induction charging proves to be a more effective and convenient option.

Tesla confirms that it finally solved its 4680 battery’s dry cathode process
The suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.
Tesla has confirmed that it is now producing both the anode and cathode of its 4680 battery cells using a dry-electrode process, marking a key breakthrough in a technology the company has been working to industrialize for years.
The update, disclosed in Tesla’s Q4 and FY 2025 update letter, suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.
Dry cathode 4680 cells
In its Q4 and FY 2025 update letter, Tesla stated that it is now producing 4680 cells whose anode and cathode were produced during the dry electrode process. The confirmation addresses long-standing questions around whether Tesla could bring its dry cathode process into sustained production.
The disclosure was highlighted on X by Bonne Eggleston, Tesla’s Vice President of 4680 batteries, who wrote that “both electrodes use our dry process.”
Tesla first introduced the dry-electrode concept during its Battery Day presentation in 2020, pitching it as a way to simplify production, reduce factory footprint, lower costs, and improve energy density. While Tesla has been producing 4680 cells for some time, the company had previously relied on more conventional approaches for parts of the process, leading to questions about whether a full dry-electrode process could even be achieved.
4680 packs for Model Y
Tesla also revealed in its Q4 and FY 2025 Update Letter that it has begun producing battery packs for certain Model Y vehicles using its in-house 4680 cells. As per Tesla:
“We have begun to produce battery packs for certain Model Ys with our 4680 cells, unlocking an additional vector of supply to help navigate increasingly complex supply chain challenges caused by trade barriers and tariff risks.”
The timing is notable. With Tesla preparing to wind down Model S and Model X production, the Model Y and Model 3 are expected to account for an even larger share of the company’s vehicle output. Ensuring that the Model Y can be equipped with domestically produced 4680 battery packs gives Tesla greater flexibility to maintain production volumes in the United States, even as global battery supply chains face increasing complexity.

Tesla Giga Texas to feature massive Optimus V4 production line
This suggests that while the first Optimus line will be set up in the Fremont Factory, the real ramp of Optimus’ production will happen in Giga Texas.
Tesla will build Optimus 4 in Giga Texas, and its production line will be massive. This was, at least, as per recent comments by CEO Elon Musk on social media platform X.
Optimus 4 production
In response to a post on X which expressed surprise that Optimus will be produced in California, Musk stated that “Optimus 4 will be built in Texas at much higher volume.” This suggests that while the first Optimus line will be set up in the Fremont Factory, and while the line itself will be capable of producing 1 million humanoid robots per year, the real ramp of Optimus’ production will happen in Giga Texas.
This was not the first time that Elon Musk shared his plans for Optimus’ production at Gigafactory Texas. During the 2025 Annual Shareholder Meeting, he stated that Giga Texas’ Optimus line will produce 10 million units of the humanoid robot per year. He did not, however, state at the time that Giga Texas would produce Optimus V4.
“So we’re going to launch on the fastest production ramp of any product of any large complex manufactured product ever, starting with building a one-million-unit production line in Fremont. And that’s Line one. And then a ten million unit per year production line here,” Musk stated.
How big Optimus could become
During Tesla’s Q4 and FY 2025 earnings call, Musk offered additional context on the potential of Optimus. While he stated that the ramp of Optimus’ production will be deliberate at first, the humanoid robot itself will have the potential to change the world.
“Optimus really will be a general-purpose robot that can learn by observing human behavior. You can demonstrate a task or verbally describe a task or show it a task. Even show it a video, it will be able to do that task. It’s going to be a very capable robot. I think long-term Optimus will have a very significant impact on the US GDP.
“It will actually move the needle on US GDP significantly. In conclusion, there are still many who doubt our ambitions for creating amazing abundance. We are confident it can be done, and we are making the right moves technologically to ensure that it does. Tesla, Inc. has never been a company to shy away from solving the hardest problems,” Musk stated.
