NASA may prematurely kill long-lived Mars rover with arbitrary wake-up deadline
In a decision with no obvious empirical explanation, JPL’s Opportunity Mars rover project manager John Callas was quoted in an August 30th press release saying that the NASA field center would be “forced to conclude” that the dust storm-stricken rover was effectively beyond saving if it fails to come back to life 45 days after 2018’s massive dust storm can be said to have officially ended.
Below the upbeat-sounding title of this press release is the scarier fact that after tau clears below 1.5, the rover has 45 days to wake up before NASA stops actively trying to revive it. Come on, #WakeUpOppy https://t.co/piCQLeaCEO

Over the course of that press release, Callas made a number of points that may technically hold at least a few grains of truth, but entirely fail to add up to any satisfactory explanation for the choices described therein. This is underscored in one critical and extended quote:
“If we do not hear back [from Opportunity] after 45 days, the team will be forced to conclude that the Sun-blocking dust and the Martian cold have conspired to cause some type of fault from which the rover will more than likely not recover. At that point, our active phase of reaching out to Opportunity will be at an end. However, in the unlikely chance that there is a large amount of dust sitting on the solar arrays that is blocking the Sun’s energy, we will continue passive listening efforts for several months.” – John Calwell, JPL
Scott Maxwell, a former JPL engineer who led drive planning for rovers Spirit and Opportunity, solidly explained the differences between active and passive recovery attempts:
Because it's a FAQ … "active listening" has two parts: (1) forcing Opportunity's radio, if she's listening, to a particular frequency (because it can drift), and (2) a command to talk to us. Pretty much guaranteed to work if she's awake with her radio on. https://t.co/iaHbHXFKqm

The JPL press release offers exactly zero explanation for the “45-day” deadline, starting the moment that dust clears from Martian skies near Opportunity to a certain degree, likely to happen within the next few weeks. Nor does it explain why “active” recovery attempts would stop at that point, despite the fact that the PR happens to directly acknowledge the fact that the best time to attempt to actively restore contact Opportunity might be after Mars’ windy season is given a chance to blow accumulated dust off of the rover’s solar arrays.
In fact, while all points Callas/the press release makes may theoretically be valid, the experiences of the actual engineers that have been operating Opportunity and MER sister rover Spirit for nearly two decades suggest that his explanations are utterly shallow and fail even the most cursory comparison with real data.
Thanks largely to a number of comments collected by The Atlantic from past, present, and anonymous employees involved with Opportunity, it would seem that there is no truly empirical way to properly estimate the amount of dust that may or may not be on the rover’s solar arrays, no rational engineering-side explanation for the 45-day ultimatum, no clear excuse for how incredibly short that time-frame is, and essentially zero communication between whoever this decision originates from and the engineers tasked with operating and restoring communications with the forlorn, 15-year old rover.
Most tellingly, this exact impromptu dust-storm-triggered hibernation already occurred several times in the past, and even resulted in the demise of Opportunity’s sister rover Spirit in 2010. The Atlantic notes that when a dust storm forced that rover into hibernation in 2010, JPL mission engineers spent a full ten months actively attempting to resuscitate Spirit, followed by another five months of passive listening before the rescue effort was called off.
Given that Opportunity’s engineers appear to believe that there is every reason to expect that the rover can, has, and should survive 2018’s exceptional Martian dust storm, the only plausible explanation for the arbitrary countdown and potentially premature silencing of one of just two active rovers on Mars is purely political and financial. While it requires VERY little money to operate scientific spacecraft when compared with manufacturing and launch costs, the several millions of dollars needed to fund operations engineers and technicians (roughly $15 million per year for Opportunity) could technically be funneled elsewhere or the employees in question could be redirected to newer programs.
For example, the ~$200 million spent operating the rover from 2004 to 2018 could instead fund considerably less than 20% of the original cost of building and launching both Opportunity and Spirit. This is to say that that cutting operation of functioning spacecraft to save money can be quite fairly compared with throwing an iPhone in the trash because the charging cable ripped because $10 could instead be put towards buying a new phone months or years down the line.
Ultimately, all we can do is hope that Opportunity manages to successfully wake up over the course of the next two or three months. If the rover is unable to do so, chances are sadly high that it will be lost forever once active communications restoration efforts come to an end. With an extraordinarily productive 15 years of exploration nearly under its belt, Opportunity – originally designed with an expected lifespan of ~90 days – would leave behind a legacy that would fail to disappoint even the most ardent cynic. Still, if life may yet remain in the rover, every effort ought to be made to keep the intrepid craft alive.

Tesla has expanded the footprint of a massive safety feature worldwide with a recent Software Update labeled as 2026.20.6. The expansion of the “Blind Spot Warning While Parked” feature represents the more widespread availability of the feature, which aims to prevent “dooring.”
Dooring is when a driver or passenger opens a car door into the path of an oncoming road user, usually a cyclist or motorcyclist. It is among the most common types of cycling accidents, the League of American Bicyclists says.
For this reason, Tesla created a feature that warns occupants not to open the door because an object is approaching. The feature will sound a chime, and it will also delay the opening of the door to prevent an incident.
The release notes state (via Not a Tesla App):
“If you attempt to open a door while an approaching object is detected in your blind spot (for example, a bicyclist approaching from behind) a chime sounds, and your door will not open upon initial button press. Wait a short time and press the button a second time to override the warning.”
Tesla initially rolled out this feature back in 2024 with the Model 3 “Highland.” However, it remained with the Model 3 exclusively for over a year; that was until Tesla added it to the Cybertruck this past Spring.
Now, it is making its way to the new Model Y, 2021 and newer Model S, and 2021 or newer Model X.
The prevention of dooring incidents could eliminate many injuries to cyclists, especially in an urban setting. Dooring accounts for 10-20 percent of bike-related crashes in major cities, and over 17,000 dooring-related incidents were treated in the U.S. over the course of a decade. These usually involve fractures, contusions, and head trauma.
Tesla confirmed this morning that it has sent the first production units, manufactured with no steering wheel or pedals, to on-road testing in Austin, sharing video of the first rides with no human controls.
The lack of steering wheels and pedals in the Cybercab aligns with Tesla’s self-certification of Robotaxi as Level 4 SAE, a platform it plans to make widespread through internal vehicles and customer-owned cars that will operate and generate revenue for individuals.
The start of these engineering tests is a major signal for Tesla, which plans to bring driverless, wheel-less, and pedal-less Cybercabs to market in the coming months. With production already well underway at Gigafactory Texas, where the Cybercab is built, there is some inclination to believe the first public rides could happen sooner rather than later.

Tesla’s engineering tests will put the Cybercab in real-world scenarios, testing not only the hardware, but more importantly, the software that drives the car around Austin with nobody supervising it within the car.
This is perhaps the biggest part of the internal testing process, especially prior to allowing regular, everyday people to hail the Cybercab for an autonomous ride. These early rides serve as a true benchmark for Tesla: How many rides can it achieve safely? How many miles did it travel consecutively without needing an intervention? What scenarios challenge the Full Self-Driving suite the most?
The proper precautions have already been put into place as well, as Tesla released the First Responders Guide to Cybercab over the weekend, ensuring that emergency services have 24/7 access to Robotaxi Assistance, as well as other boundaries, such as Geofencing features that can be used to redirect autonomous vehicle traffic due to accidents, road closures, construction, or maintenance.
Cybercab seems genuinely close to being added to the Robotaxi fleet in Austin, but Tesla has prioritized safety throughout this entire process. Therefore, we think it could be months before it truly starts giving rides to the public. People have been frustrated with this, but Robotaxi in Austin has a tremendous safety record so far, so the slow rollout has kept people safe and accidents to a minimum.
The most important thing is that Tesla continues to show consistent progress in the Cybercab’s ramp-up toward fleet addition. A few weeks back, we saw the EPA reward the Cybercab a Certificate of Conformity, allowing it to enter the stream of commerce. Then, we saw Tesla add decals, signaling that it was likely about to start testing it publicly. That has now happened.
The next big move will be the announcement of the first rides, so this Summer should be filled with anticipation.
For years, there have been images and videos across social media platforms that have reminded me of when I was a 15-year-old kid teased by “Xbox 720” videos on YouTube. These videos are of the supposed “Tesla Phone” that Elon Musk was secretly developing in between leading Tesla with its electric cars and SpaceX with its reusable rockets.

Although Musk has put those rumors to bed several times, it was never completely out of the realm that he could get involved in cell phones in some capacity. Think outside the box and more macro-level, though. Instead of reinventing the computer, Musk reinvented connectivity by developing Starlink with SpaceX.
It could be something similar, TD Cowen analyst Gregory Williams said in a note last week, where he hinted SpaceX could be gathering some steam to acquire T-Mobile.
Williams said it would be the “clear choice” for SpaceX if it decided to go through with a network acquisition. He also suggested AT&T.
The move would be possible through selling more of its own stock, which would help SpaceX raise the money to purchase T-Mobile, which would cost roughly $300 billion. It could be one of the moves SpaceX makes post-IPO in terms of an acquisition: it already acquired Cursor AI for $60 billion.
Other analysts, like Dan Ives of Wedbush, believe SpaceX and Tesla will eventually merge into one anyway, and that conglomeration could come as soon as this year, some have said.
The implications of SpaceX purchasing T-Mobile are massive. A combined entity would create a truly ubiquitous network: T-Mobile’s terrestrial 5G towers and Starlink’s growing constellation of Direct-to-Cell satellites. This would essentially eliminate dead zones across the U.S. and potentially globally.
SpaceX would instantly become a full-scale facilities-based carrier with satellite differentiation; a huge advantage. This would pressure AT&T and Verizon heavily.
There are also concerns like a potential reduction in long-term competition, and of course, a deal of that size would face intense scrutiny from government agencies.
The strategic fit is compelling due to the existing Starlink–T-Mobile partnership and complementary technologies (space + terrestrial). It could create a dominant integrated communications player. However, the regulatory, financial, and execution hurdles are enormous — this remains highly speculative with no indication SpaceX is actively pursuing it right now.
