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 has a Cybercab problem nobody saw coming
Tesla’s Cybercab line now builds robotaxis faster than Tesla can deploy them, Lars Moravy says.
Tesla’s Cybercab line in Texas can now build the two seat robotaxi faster than the company can put it into service, according to Lars Moravy, Tesla’s Vice President of Vehicle Engineering. “We don’t run every day because the line can run so fast. It’s currently outpacing our deployments,” Moravy said in a new Cybercab deep dive from Munro Live. “So, it’s a bit of a race right now. Who’s going to go faster? Right now the manufacturing line’s ahead.”
Tesla’s official Robotaxi account shared a Cybercab analysis video on X on Monday, calling it a “Cybercab engineering deep dive.” Moravy’s comments go further than what he told analysts on the Q3 earnings call last week, when he said the Cybercab line’s listed capacity of more than 125,000 units a year undersells what it can actually run.
The tour shows where that speed comes from. Tesla’s unboxed process splits the Cybercab into front, rear, side and center modules that are built and tested on their own before they meet on a short final line. That final line has just 25 fully automated stations, which Tesla’s team estimated is a fifth to a tenth of what a Model Y needs. The full line is about 78% automated, the framing line is already at 100%, and the layout uses roughly 50% less floor space per vehicle. The stated goal is “100% automation in 10 second cycle time,” or one finished Cybercab every 10 seconds.
Tesla also deleted the paint shop. Only the side modules are coated, and the exterior panels get their color inside the molding machine. Engineers said the car is designed to run at least 500,000 miles, which matters for a vehicle that will spend most of its day carrying riders.
The battery got the same treatment. The Cybercab uses an 88S6P pack of 4680 cells in a steel enclosure, a first for Tesla, with each module potted separately so a single failed module can be swapped instead of the whole pack. Wireless battery management boards replace a wiring harness, and new contactors are fast enough to drop the pyro fuse entirely. Tesla’s battery director graded the pack an A minus, compared with a D for the Model Y structural pack and a B minus for Cybertruck. Up front, the drive unit runs an 11:1 gear ratio versus roughly 9:1 on most Teslas, since the Cybercab does not need a high top speed.

The deployment side is now the bottleneck Moravy described. Tesla had more than 50 Cybercabs working the Formula 1 weekend in Austin, and Texas records show 463 Cybercabs registered. Tesla said on its earnings call that Cybercab service will launch in Dallas next month, and Moravy said the company is aiming to get Cybercabs to customers by the end of 2026. Every unit built so far has gone into Tesla’s own fleet since the line moved into volume production in April.
Munro Live also asked when it could get a Cybercab to tear down. Tesla’s answer: “Not yet.”
SpaceX’s Raptor engine family has steadily increased sea-level thrust while simultaneously reducing mass, turning iterative engineering gains into substantially higher performance for the Super Heavy booster. CEO Elon Musk shed more light on how powerful Raptor 4 will be, and it’s pretty crazy.
Raptor 1 delivered 185 metric tons of thrust at roughly 2,080 kilograms, while Raptor 2 raised that to 230 tons while cutting mass to about 1,630 kilograms. SpaceX data for Raptor 3 lists a target of 280 tons at 1,525 kilograms (with further reductions in associated vehicle hardware), while operational flight ratings have been cited near 250 tons.
This morning, Elon Musk stated that Raptor 4 is expected to reach 300 tons of sea-level thrust at roughly the same mass as Raptor 3. Across these versions, thrust has risen by more than 60 percent from the first engines while engine mass has fallen, producing a sharp improvement in thrust-to-weight ratio. This is a true testament to how great SpaceX engineering has been:
🚀 Elon says Raptor 4 will make 300 tons of thrust at sea level at roughly the same mass as Raptor 3.
How far Raptor has come:
Raptor 1: 185 tf, 2,080 kg
Raptor 2: 230 tf, 1,630 kg
Raptor 3: 250 tf, 1,525 kg
Raptor 4: 300 tf33 on Super Heavy = ~9,900 tf, nearly 3x Saturn V https://t.co/HQDswZhyvL

With 33 engines on SuperHeavy, the jump from earlier versions to a 300-ton Raptor 4 would produce roughly 9,900 metric tons of total liftoff thrust, nearly three times the Saturn V’s approximately 3,400 metric tons from its five F-1 engines.
This is not just a larger number on a data sheet, either, as sea-level thrust is the force available the moment the vehicle leaves the pad. This is when it is heaviest and still deep in Earth’s gravity well and dense atmosphere.
Higher levels of sea-level thrust directly improves the initial thrust-to-weight ratio of the full stack. A higher ratio produces faster acceleration off the pad, which shortens the time the rocket has to spend fighting gravity, and gravity losses during the first minute or two of the flight are a major drain on total available delta-v. Every second shaved off of that early climb preserves more propellant energy for reaching orbital velocity or for carrying extra payload.
Because Super Heavy’s engine count is constrained by vehicle diameter and packing density, increasing thrust per engine is the most straightforward way to raise total liftoff performance without redesigning the booster structure or design.
The same-mass target for Raptor 4 is equally important. Holding engine mass roughly constant while raising thrust improves the engine’s own thrust-to-weight ratio and reduces the structural and propellant mass fraction that must be carried solely to support the engines.
Earlier Raptor iterations also simplified or eliminated extensive vehicle-side hardware such as heat shields. These gains compound: more force for less installed mass leaves additional capacity for propellant, payload, or operational margins such as engine-out capability.
For Starship’s architecture, the practical effects are large. Greater liftoff thrust supports heavier vehicles, larger propellant loads, and higher payloads to low Earth orbit, figures SpaceX has targeted in the 100-plus-ton reusable range. That capacity underpins orbital refueling, lunar missions, and eventual Mars cargo and crew flights.
Continued growth in sea-level thrust therefore tightens the gap between theoretical rocket performance and the high flight rates and reusability needed to make large-scale space transport practical.
Tesla has expanded its Tesla Assisted Driving (TAD) suite to its tenth European country, as Latvia joined a growing list of European Union member states authorizing the company’s advanced driver assistance technology.
Tesla Europe announced this morning that the system is now approved in Latvia, with a software rollout to begin soon.
The approval and rollout follow recognition of a provisional European type approval originally granted by the Netherlands’ RDW authority on April 10.
🚨 Latvia has just received approval for Tesla Full Self-Driving (Supervised)
This is the 10th country in the EU to gain approval:
1. Netherlands — 10 April 2026 (original RDW approval)
2. Lithuania — 20 May 2026
3. Estonia — 29 May 2026
4. Denmark — 9 June 2026
5. Belgium — 10 June 2026
6. Slovenia — 7 September 2026
7. Czechia — 21 September 2026
8. Croatia — 29 September 2026
9. Slovakia — 16 October 2026— TESLARATI (@Teslarati) October 26, 2026
Latvia’s Road Traffic Safety Directorate (CSDD) evaluated the Dutch documentation, coordinated with the other national authorities, and reviewed updates from Tesla. These included tightened limits on speed offsets, automatic resets of any manual speed adjustments after each trip, and stronger driver monitoring.
In Europe, the feature is marketed as Tesla Assisted Driving after a recent rule change that labeled the name “Full Self-Driving” as misleading.
The system remains an SAE Level 2 driver assistance tool, not unsupervised autonomy. It can control speed, steering, braking, lane changes, and intersections while following a navigation route. Drivers need not keep their hands on the wheel at all times, yet they must continuously monitor the road and be prepared to intervene immediately.
The sequence of EU recognitions began with the Netherlands in April and continued through Lithuania, Estonia, Denmark, Belgium, Slovenia, Czechia, Croatia, and Slovakia. Most have relied on mutual recognition of the single Dutch provisional approval rather than independent national testing.
These national clearances do not yet constitute bloc-wide authorization. An EU-wide decision requires a qualified majority in the Technical Committee on Motor Vehicles: at least 15 of 27 member states representing 65 percent of the EU population. Larger markets, like Germany, France, and Italy, remain under review, and a vote is expected this December.
However, for Latvian Tesla owners with compatible vehicles and software, the imminent rollout expands access to the supervised system while underscoring that attentive human oversight remains essential.
