NASA officially says goodbye to Mars Opportunity rover lost in massive dust storm
After 15 years roving around our neighboring red planet, NASA announced the end of its Opportunity rover mission on Mars today during a live conference held at 2 pm EST. The rover’s team of scientists spent last night sending a set of commands intended to be the last attempt at waking Opportunity, and this afternoon’s announcement confirmed the final fate of the mission. A planet-wide dust storm in summer of 2018 shut the Martian rover down due to its solar panels being blocked from debris, and the long duration spent without power apparently led to a series of failures which prevented a recovery. The last communication NASA received from Opportunity was on June 10, 2018.
#OppyPhoneHome Update
Tonight, we’ll make our last planned attempts to contact Opportunity. The solar-powered rover last communicated on June 10, 2018, as a planet-wide dust storm swept across Mars.

Over the last few months, while scientists continued to revive Opportunity, hopes were fairly high that communication would be reestablished. The rover’s batteries were in good health prior to the dust storm, and the surface temperature was relatively warm when the storm began. Also, its programming was designed with “fault modes” allowing actions to be taken automatically to maintain the rover’s health. The team at NASA had attempted to talk to Opportunity several times per week once the storm began to clear using the Deep Space Network, an international array of giant radio antennas supporting interplanetary spacecraft missions, and over 600 attempts were made without any response received. The announcement was broadcast live via NASA’s website.
Emotions were high during NASA’s mission end announcement. Associate NASA Administrator Thomas Zurbuchen began the event’s commentary: “I stand here, surrounded by the team…it’s an emotional time,” he began. “Science is a team sport, and that’s what we’re celebrating today.” NASA Administrator Jim Bridenstine noted that while Opportunity stopped communicating around the same time be began his service with the administration, he was still in awe at the achievements the rover and its team were able to achieve throughout their mission. “When this little rover landed, the objective was to have it move 1100 yards and survive for 90 days,” he exclaimed before reiterating the unexpected 15 years the mission eventually lasted. Michael Watkins, Director of NASA’s Jet Propulsion Laboratory commented on the mission’s broader contribution to society: “Spirit and Opportunity energized the public about the spirit of Mars exploration.”
John Callas, project manager of NASA’s Mars Exploration Rover (MER) project, provided some insight about what could have caused Opportunity to shut down for good. Earlier in Opportunity’s mission days, a heater on its robotic arm failed to turn off, draining the rover’s energy in the process. To overcome this issue, the team at NASA designed a deep sleep mode which shut down nearly everything on Opportunity, including the heater. Callas surmised that the dust storm which ended the rover’s mission may have disrupted its sleep cycle, reinstating the power draining issue and preventing recovery. He also described the quality of Opportunity’s batteries and the seasonal reliability of the Martian winds to clean its solar panels as part of the reasons it lasted as long as it did. Finally, Callas had his own farewell comments to add. “Even though it’s a machine, saying goodbye, it’s very hard and very poignant,” he remarked.

NASA’s Opportunity rover (nicknamed “Oppy”) launched on July 7, 2003, aboard a Delta II rocket from Cape Canaveral, Florida. Its primary mission was to search for and characterize rocks and soil while looking for indications of water activity in the Martian past. One of the better-known discoveries made by the rover was the discovery of hematite on the surface, a mineral which typically forms in water. Also found were strips of gypsum in rocks around a crater, indicating that water most likely flowed through the area at one point. The storm which finally ended the rover’s mission was intense and massive, its size is roughly the area of North America and Russia combined with Opportunity in the center.
A month prior to Opportunity’s launch, its twin rover Spirit headed for Mars with a similar mission. Both rovers lasted years longer than their 90-day expected life span, but unfortunately, Spirit’s mission ended before Opportunity’s when it became lodged in soft soil at a site called “Troy”. NASA ended its rescue effort of Spirit in May 2011. Another NASA rover named Curiosity is still crawling the planet, however. Its plutonium-nuclear power source helped it avoid the same fate that came over its predecessor, even sending back a storm-riding selfie during the event that claimed Opportunity.
NASA’s most recent mission to Mars was its InSight lander, a geological science mission sent to study the core of the planet and atmosphere. After arriving at the red planet in late November 2018 with twin CubeSat mission MarCo, it successfully landed without incident and sent a dusty photo back for Earthling enjoyment and arrival confirmation. In the months since it’s treated NASA and the public alike with selfies and the sound of Martian wind. Its instruments have recently been placed on the surface, so new planet data is expected soon.
Up next for the fourth rock from the Sun will be Mars 2020, an advanced rover dedicated to high-priority science missions including the search for habitable conditions and microbes in the ancient past. NASA plans to launch this rover in July 2020.

Tesla Semi factory is getting a celebration nobody expected
Tesla will inaugurate its Nevada Semi factory September 24, five months after production quietly began ramping.
Tesla says it will officially inaugurate its new Semi factory in Nevada next month. The Tesla Semi account posted the announcement on X, sharing a graphic titled “Semi Rollout” with a date of September 24. No further details were given about the format of the event or who would attend.
While Tesla’s dedicated Semi plant in Sparks, adjacent to Gigafactory Nevada, opened back in April, with the first trucks rolling off the high volume line on April 29, the timing for the factory inauguration comes at a surprise. The ribbon cutting event five months into production is a break from how Tesla has usually handled its other factories, where the first truck or car off the line typically served as the milestone moment.

The 1.7 million square foot factory was built as part of a $3.6 billion expansion Tesla announced in early 2023, and it shares a site with the battery cell lines that feed the Semi’s structural pack, a decision meant to remove the supply bottleneck that delayed the truck for years. The plant is designed for 50,000 trucks a year at full ramp. Semi program director Dan Priestley has said production “is now ramping” rather than claiming it has reached scale.
Nine years passed between the Semi’s 2017 unveiling and this stage of production, with the truck slipping from an original 2019 target through hand built pilot units for PepsiCo and a slow build out of the Nevada plant. An inauguration event now gives Tesla a stage to talk up that ramp and reset expectations for how many trucks it can begin delivering at scale.
The September date also lines up with the Semi’s next milestone. Tesla confirmed the truck is heading to Europe with a full unveiling at the IAA Transportation trade show in Hannover, Germany, running September 15 through 20. Between the Nevada event and the Hannover reveal, Tesla has roughly a week and a half in September to make the case that the Semi is now a truck being built and sold on two continents rather than tested in a handful of fleets.

Elon Musk just set a condition that could end Falcon 9 as we know it
Elon Musk says SpaceX will finally retire Falcon 9 once Starship flies reliably every week.
Elon Musk gave the clearest timeline yet for retiring Falcon 9, SpaceX’s workhorse rocket.
The comment came in a reply on X, where Musk wrote that “once Starship is flying reliably several times per week, it makes sense to shift super scarce SpaceX engineering and production resources to Starship to get launch rate to several times per day, which means winding down Falcon.” He was responding to physicist Casey Handmer, who noted that NASA is reportedly uneasy about SpaceX phasing out Falcon after building what Handmer called the most successful launcher ever, with the fleet nearing 1,000 total launches.
Now @SciGuySpace reports NASA is in a tizzy because after running the most successful launcher ever for more than a decade and nearing 1000 launches, @SpaceX is planning to retire Falcon in favor of Starship in a few years.
Sorry, NASA, you’ve had 15 years to burn down the… https://t.co/uCNoMwK0v9

Falcon 9 is still SpaceX’s busiest vehicle by far. The company is on pace for roughly 140 to 145 Falcon flights this year, following 165 in 2025, president Gwynne Shotwell told Time earlier in 2026. She has already said Falcon flights would “tail off” as Starship comes online, while reports indicate that SpaceX has stopped booking new Falcon 9 launches past 2028 and halted production of some expendable Falcon hardware, according to Bloomberg.
It’s worth noting that Musk’s post is a condition, and not a countdown on when Falcon will retire. Starship has not yet flown weekly, let alone daily. Its most recent flight in July ended with a soft splashdown in the Indian Ocean, a milestone Musk pointed to earlier this month when he said the vehicle’s heat shield problem was effectively solved. SpaceX towed that ship to Christmas Island for inspection, and the next flight, Flight 14, is aimed at putting Starship into orbit for the first time. A tower catch attempt for the upper stage has been pushed back to what Musk has called “a few months” away.
SpaceX and a new Trump order that could rewrite the next decade of launches
The gap between Falcon’s role today and Starship’s promised role tomorrow matters most to NASA. Falcon and its Dragon capsule remain the only way the agency rotates astronauts to and from the International Space Station, and Starship is not certified to carry NASA crews. Musk’s post did not address how that handoff would work if Falcon winds down before a crew-rated Starship variant exists. The timing lines up with Musk’s other recent Starship comments. Two days before the Falcon post, he told a different X user that SpaceX is aiming for more than 30 Starship launches a day by 2030, or roughly 10,000 a year, a figure tied to the Trump administration’s new push for higher national launch cadence. Falcon, which took over a decade to reach its first 100 launches, was never built to approach that kind of volume.
For now, Falcon 9 keeps flying at a near-record pace while Starship works to prove it can do the job Musk has already picked out for it.
Tesla Cybercab is set to launch in Austin, Texas, on September 3, as the company has officially started sending out invitations to a dedicated event it will hold in the city where its headquarters is located.
The Cybercab is Tesla’s dedicated ride-sharing vehicle: it features just two seats and has no steering wheel or pedals. It is aimed at fully autonomous passenger transport, and will operate in the Robotaxi fleet alongside the Tesla Model Y, which has been performing driverless rides for real-world passengers for more than a year.
Thank you so much @Tesla for inviting us to the Cybercab launch in Austin! 🤠 pic.twitter.com/F1rAR8zd5O

The launch of the Cybercab marks the next chapter in Tesla’s autonomy story. The company has been developing autonomous transport for years with its Full Self-Driving (Supervised) platform, which is available in any vehicle the company has built with the proper hardware and software capabilities.
Its capabilities vary by hardware and software version, but Tesla says its latest hardware version, known as AI4, can deliver full autonomy. However, future vehicles will operate with even more robust hardware packages, as Tesla will develop AI4.5 and AI5 for even more capability in its vehicles.
Following a report from The Information that surfaced earlier this week, the writing was on the wall that Tesla was set to launch Cybercab in the near term. The report stated Tesla could launch Cybercab as soon as the end of August. Tesla came close and has booked it for September 3.
The big thing with this event being scheduled is not necessarily that Tesla is launching a new vehicle, but instead that it is launching a vehicle that has no steering wheel or pedals and will operate exclusively on a self-driving program that is evidently nearing full autonomy. If the event allows vehicles to take passengers on public roads and drop them off wherever they please within the City of Austin, it will be a drastic advancement in the company’s self-driving story.
People have ridden in Cybercab previously: Tesla had the “We, Robot” event in October 2024, which allowed people to experience fully autonomous rides in a closed circuit at Warner Bros. Studios in Burbank.

Additionally, Tesla launched employee rides in Cybercab in July.
It’s a drastic step forward for Tesla, whose CEO, Elon Musk, has promised for years that the company would release a fully autonomous vehicle and platform capable of allowing drivers to relinquish any responsibility behind the wheel.
