SpaceX’s Crew-1 NASA astronauts celebrate Mars rover landing in Earth orbit
SpaceX’s Crew-1 NASA astronauts and the rest of the International Space Station crew are celebrating the space agency’s latest historic Mars landing in Earth orbit.
The culmination of more than half a decade of work and a several hundred million million mile journey through deep space, NASA and the Jet Propulsion Laboratory have managed to make lightning strike twice, successfully landing a second car-sized rover on the surface of Mars. Carrying a bevy of cutting-edge science instruments – many of which are on the Red Planet for the first time – and even a small helicopter-like drone, the Mars 2020 Perseverance rover is now ready for a careful once-over before kicking off a what should be a years-long science campaign.
If all goes as planned, part of that campaign will involve collecting an extensive series of Martian soil samples that could eventually be recovered and launched back to Earth in the late 2020s or 2030s. In the meantime, the Perseverance rover – nicknamed ‘Percy’ – will essentially operate as a supercharged, upgraded version of Curiosity, an almost identical car-sized rover that debuted NASA and JPL’s powered descent and landing capabilities in 2012.
Curiosity continues to roam Mars with no signs of slowing down and is making slow but steady progress on a marathon climb up the outskirts of Mount Sharp. While roughly the same size as Percy, Curiosity’s younger sibling carries an almost entirely revamped set of scientific instruments and is substantially heavier, meaning that the Mars 2020 mission represents the first time history that a spacecraft weighing more than one metric ton (1025kg/2260lb) has successfully landed on another planet.
Unlike SpaceX, which has long prioritized trial and error and extensive incremental testing on the path to developing new technologies and capabilities, NASA and JPL – for a variety of complex reasons – are under an incredible amount of pressure to succeed on the first try. That’s particularly apparent with missions like Curiosity and Perseverance, where the slightest error could easily doom a $2.5 billion work of art, engineering, and science to a crater on the surface of its target destination.
-->The sheer insanity of injecting a car-sized rover into another planet’s atmosphere – with no prior braking of any kind – at around 10 times the speed of a bullet, deploying a house-sized parachute at supersonic velocities, and ultimately dropping that rover to the surface of Mars with a literal rocket-powered ‘sky crane’ is hard to exaggerate. The fact that that was what hundreds of the world’s smartest people concluded was the safest and most optimal architecture exemplifies just how extraordinarily difficult large-scale Mars landings really are.
With any luck, in 5-10 years, NASA, SpaceX, and the world will be watching with bated breath as Starship attempts its first Mars atmospheric entry, descent, and landing and (most likely) explodes somewhere in the middle. Regardless, SpaceX will be – and is, even today – standing on the shoulders of giants like those that just bullied the laws of physics and complexities of systems engineering into submission to land a second car-sized rover on Mars.

SpaceX’s Starship program is already bouncing back from Booster 18 fiasco
Just over a week since Booster 18 met its untimely end, SpaceX is now busy stacking Booster 19, and at a very rapid pace, too.
SpaceX is already bouncing back from the fiasco that it experienced during Starship Booster 18’s initial tests earlier this month.
Just over a week since Booster 18 met its untimely end, SpaceX is now busy stacking Booster 19, and at a very rapid pace, too.
Starship V3 Booster 19 is rising
As per Starbase watchers on X, SpaceX rolled out the fourth aft section of Booster 19 to Starbase’s MegaBay this weekend, stacking it to reach 15 rings tall with just a few sections remaining. This marks the fastest booster assembly to date at four sections in five days. This is quite impressive, and it bodes well for SpaceX’s Starship V3 program, which is expected to be a notable step up from the V2 program, which was retired after a flawless Flight 11.
Starship watcher TankWatchers noted the tempo on X, stating, “During the night the A4 section of Booster 19 rolled out to the MegaBay. With 4 sections in just 5 days, this is shaping up to be the fastest booster stack ever.” Fellow Starbase watcher TestFlight echoed the same sentiments. “Booster 19 is now 15 rings tall, with 3 aft sections remaining!” the space enthusiast wrote.
Aggressive targets despite Booster 18 fiasco
SpaceX’s V3 program encountered a speed bump earlier this month when Booster 18, just one day after rolling out into the factory, experienced a major anomaly during gas system pressure testing at SpaceX’s Massey facility in Starbase, Texas. While no propellant was loaded, no engines were installed, and no one was injured in the incident, the unexpected end of Booster 18 sparked speculation that the Starship V3 program could face delays.
-->Despite the Booster 18 fiasco, however, SpaceX announced that “Starship’s twelfth flight test remains targeted for the first quarter of 2026.” Elon Musk shared a similar timeline on X earlier this year, with the CEO stating that “ V3 is a massive upgrade from the current V2 and should be through production and testing by end of year, with heavy flight activity next year.”
Considering that Booster 19 seems to be moving through its production phases quickly, perhaps SpaceX’s Q1 2026 target for Flight 12 might indeed be more than feasible.

Elon Musk makes a key Tesla Optimus detail official
“Since we are naming the singular, we will also name the plural, so Optimi it is,” Musk wrote on X.
Tesla CEO Elon Musk just made a key detail about Optimus official. In a post on X, the CEO clarified some key wording about Optimus, which should help the media and the public become more familiar with the humanoid robot.
Elon Musk makes Optimus’ plural term official
Elon Musk posted a number of Optimus-related posts on X this weekend. On Saturday, he stated that Optimus would be the Von Neumann probe, a machine that could eventually be capable of replicating itself. This capability, it seems, would be the key to Tesla achieving Elon Musk’s ambitious Optimus production targets.
Amidst the conversations about Optimus on X, a user of the social media platform asked the CEO what the plural term for the humanoid robot will be. As per Musk, Tesla will be setting the plural term for Optimus since the company also decided on the robot’s singular term. “Since we are naming the singular, we will also name the plural, so Optimi it is,” Musk wrote in his reply on X.
This makes it official. For media outlets such as Teslarati, numerous Optimus bots are now called Optimi. It rolls off the tongue pretty well, too.
Optimi will be a common sight worldwide
While Musk’s comment may seem pretty mundane to some, it is actually very important. Optimus is intended to be Tesla’s highest volume product, with the CEO estimating that the humanoid robot could eventually see annual production rates in the hundreds of millions, perhaps even more. Since Optimi will be a very common sight worldwide, it is good that people can now get used to terms describing the humanoid robot.
-->During the Tesla 2025 Annual Shareholder Meeting, Musk stated that the humanoid robot will see “the fastest production ramp of any product of any large complex manufactured product ever,” starting with a one-million-Optimi-per-year production line at the Fremont Factory. Giga Texas would get an even bigger Optimus production line, which should be capable of producing tens of millions of Optimi per year.

Tesla is improving Giga Berlin’s free “Giga Train” service for employees
With this initiative, Tesla aims to boost the number of Gigafactory Berlin employees commuting by rail while keeping the shuttle free for all riders.
Tesla will expand its factory shuttle service in Germany beginning January 4, adding direct rail trips from Berlin Ostbahnhof to Giga Berlin-Brandenburg in Grünheide.
With this initiative, Tesla aims to boost the number of Gigafactory Berlin employees commuting by rail while keeping the shuttle free for all riders.
New shuttle route
As noted in a report from rbb24, the updated service, which will start January 4, will run between the Berlin Ostbahnhof East Station and the Erkner Station at the Gigafactory Berlin complex. Tesla stated that the timetable mirrors shift changes for the facility’s employees, and similar to before, the service will be completely free. The train will offer six direct trips per day as well.
“The service includes six daily trips, which also cover our shift times. The trains will run between Berlin Ostbahnhof (with a stop at Ostkreuz) and Erkner station to the Gigafactory,” Tesla Germany stated.
Even with construction continuing at Fangschleuse and Köpenick stations, the company said the route has been optimized to maintain a predictable 35-minute travel time. The update follows earlier phases of Tesla’s “Giga Train” program, which initially connected Erkner to the factory grounds before expanding to Berlin-Lichtenberg.
-->Tesla pushes for majority rail commuting
Tesla began production at Grünheide in March 2022, and the factory’s workforce has since grown to around 11,500 employees, with an estimated 60% commuting from Berlin. The facility produces the Model Y, Tesla’s best-selling vehicle, for both Germany and other territories.
The company has repeatedly emphasized its goal of having more than half its staff use public transportation rather than cars, positioning the shuttle as a key part of that initiative. In keeping with the factory’s sustainability focus, Tesla continues to allow even non-employees to ride the shuttle free of charge, making it a broader mobility option for the area.
