Boeing, NASA attempt Starliner landing after missing intended orbit
During the early morning hours of Friday, December 20th, at Space Launch Complex – 41 at Cape Canaveral Air Force Station United Launch Alliance successfully launched a uniquely configured, rated for human spaceflight Atlas V rocket topped with the Boeing Starliner crew capsule to complete its inaugural Orbital Flight Test to the International Space Station (ISS).
However, following the stunning sunrise launch and successful spacecraft separation, Starliner experienced an anomaly with an automated mission event timer which hindered a crucial orbital insertion burn from being completed.
The missed burn and the resulting domino effect of consequences cut Starliner’s journey short. In a joint media teleconference held Saturday, December 21st including NASA Administrator Jim Bridenstine, Boeing senior vice president of Space and Launch Jim Chilton, and deputy manager of NASA Commercial Crew Steve Stich, it was confirmed that just 48 hours following launch Starliner is expected conclude the test flight and return for a controlled landing at White Sands Missile Range in New Mexico.
Initially, Starliner was expected to spend approximately 8 days docked on orbit with the ISS for a return journey tentatively scheduled to occur on December 28th. The lack of orbital insertion and consequential overuse of fuel consumed by smaller incremental burns performed throughout the day on Friday to place Starliner in a safe orbit all but guaranteed that the spacecraft would miss its opportunity to rendezvous and autonomously dock with the ISS, a pivotal objective of the orbital test flight. A fact that was later confirmed on Twitter by Bridenstine.
During the teleconference, Starliner was described as a healthy spacecraft that had in fact achieved circular safe orbit approximately 250km above sea level, lower than would have been achieved had the initial burn occurred as planned. As docking with the ISS was completely out of reach and Starliner remained under tight constraints of how long it could maintain free orbital flight, Boeing and NASA teams jointly decided to bring Starliner home as soon as possible.
While Starliner remained on orbit Friday and Saturday, flight controllers completed many OFT mission objectives. A number of the achievements were outlined in a statement posted to Boeing’s Starliner updates webpage.

“Entry, descent, and landing is not for the faint of heart.” – Jim Chilton
While many OFT mission objectives were successfully met during the dramatically cut short mission the entire goal of Starliner still remains. After all, Starliner is designed to ferry human astronauts safely to and from the ISS. A huge part of that is re-entering the Earth’s atmosphere and landing under survivable conditions.
Enough of Starliner’s fuel was preserved to afford multiple opportunities to safely land. Two opportunities to land at the planned site of White Sands Space Harbor on the White Sands Missile Range in New Mexico. This location may sound familiar as it is the same location where a different Starliner test capsule recently completed a pad abort test.
NASA and Boeing teams are targeting a landing attempt on Sunday 7:57 am EST (1257 GMT). Should it be needed a backup landing attempt at 3:48 pm EST (848 GMT) in the same location is also available. An anthropomorphic test dummy dressed in Boeing’s recognizable blue spacesuit inside the capsule nicknamed “Rosie the Rocketeer” is wired up with sensors to collect data reflecting the conditions a human astronaut would experience during descent.
NASA will livestream the landing attempt and recovery efforts on NASATV beginning at 5:45 am EST (1045 GMT).

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.
