Virgin Galactic reaches space in rocket-powered plane, eyes space tourism in 2019
Virgin Galactic, the space tourism company founded by entrepreneur Richard Branson, has successfully made it to space for the first time with VSS Unity, their SpaceShipTwo-class rocket-powered plane, during the craft’s 4th test flight. This accomplishment makes Virgin the first US-based venture to carry humans to the edge of space since the Space Shuttle program ended in 2011, edging out others with similar goals such as SpaceX and Blue Origin. After taking off at 7:11 am this morning and detaching from WhiteKnightTwo, its custom airliner mothership, pilots Mark “Forger” Stucky and Rick “CJ” Sturckow reached a height 51.4 miles high in the craft to the edge of the stratosphere where they experienced weightlessness and the curvature of the Earth. This success brings the company one step closer to civilian tourist trips, something Branson hopes to achieve as early as 2019.

Unlike a traditional rocket which takes off from the ground, VSS Unity is flown to 43,000 feet underneath a specially designed airliner before being dropped and subsequently lighting up its rocket engines to power it vertically to an even higher altitude. After a 60-second engine burn speeds the craft to nearly three times the speed of sound, it continues its ascent, coasting until it reaches maximum altitude. A special “feather” system is then used for reentry, wherein the craft folds its wings and behaves like a traditional space capsule until the air thickens again, at which time the wings unfold again and behave like a space plane, gliding back to Earth and landing on a landing strip.
Becoming a passenger on one of VSS Unity’s future flights doesn’t come cheap, the price tag being $250,000 per 90-minute flight. However, given the 700 or so paid reservations, including several celebrities, it’s not the money that’s the challenge, it’s the technology. On October 31, 2014, Virgin suffered a crippling setback with the death of co-pilot Mike Alsubry and injury of pilot Peter Siebold when a predecessor craft crashed due to a combination of human error and an engineering flaw. The company received an abundance of criticism focused on whether the danger of space tourism made the rewards worthwhile, but after following recommendations set forth by the National Transportation Safety Board’s report on the incident along with further design and safety enhancements, they forged ahead to make today’s event a reality. Branson started Virgin Galactic in 2004.

At 51.4 miles high, VSS Unity reached the technical definition of space, earning its pilots commercial astronaut wings by the US Federal Aviation Administration, although the usual international standard is the 62-mile “Karman line”. A typical NASA “sounding rocket”, a small rocket generally launched with equipment on board to take measurements and scientific experiments during an approximately 30-minute sub-orbital flight only, reaches anywhere from 30-80 miles above the Earth. That said, the lower altitude of VSS Unity also provides an opportunity for research, serving the dual-purpose of science and recreation. Four research payloads from NASA’s Flight Opportunities Program were on board its historic test flight as well as a test dummy, making the trip revenue-earning for the first time as well.
Virgin Galactic has more tests of VSS Unity planned before moving to Spaceport America in New Mexico where it will set up its tourism operation. Branson hopes to compete directly with Blue Origin, the rocket company founded by Amazon’s Jeff Bezos which also plans to ferry customers to space. Bezos’s venture will use a more traditional, reusable ground-based rocket, the New Shepard, that lands after returning from sub-orbit similar to SpaceX’s Falcon 9 first stages. Unlike Virgin, crewed flights and “pre-sales” have not yet been part of Blue Origin’s process, but plenty of information is available for potential customers on its website.
The parent company of Virgin Galactic (Virgin) has another space-based venture in its wings: Virgin Orbit. Using a system similar to NASA’s Pegasus rocket, a small rocket complete with payload will launch from a modified Boeing 747-400 airliner, the combo being called LauncherOne and Cosmic Girl, respectively. The company has its sights set on the small satellite industry, identifying a need that’s not currently being met by other launch providers, and its business model centers on proving low-cost access to space for existing companies, students, entrereneurs, and other types hoping to use space as part of their research or business endeavors.

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.

Tesla Model 3 and Model Y dominate China’s real-world efficiency tests
The Tesla Model 3 posted 20.8 kWh/100 km while the Model Y followed closely at 21.8 kWh/100 km.
Tesla’s Model 3 and Model Y once again led the field in a new real-world energy-consumption test conducted by China’s Autohome, outperforming numerous rival electric vehicles in controlled conditions.
The results, which placed both Teslas in the top two spots, prompted Xiaomi CEO Lei Jun to acknowledge Tesla’s efficiency advantage while noting that his company’s vehicles will continue refining its own models to close the gap.
Tesla secures top efficiency results
Autohome’s evaluation placed all vehicles under identical conditions, such as a full 375-kg load, cabin temperature fixed at 24°C on automatic climate control, and a steady cruising speed of 120 km/h. In this environment, the Tesla Model 3 posted 20.8 kWh/100 km while the Model Y followed closely at 21.8 kWh/100 km, as noted in a Sina News report.
These figures positioned Tesla’s vehicles firmly at the top of the ranking and highlighted their continued leadership in long-range efficiency. The test also highlighted how drivetrain optimization, software management, and aerodynamic profiles remain key differentiators in high-speed, cold-weather scenarios where many electric cars struggle to maintain low consumption.
Xiaomi’s Lei Jun pledges to continue learning from Tesla
Following the results, Xiaomi CEO Lei Jun noted that the Xiaomi SU7 actually performed well overall but naturally consumed more energy due to its larger C-segment footprint and higher specification. He reiterated that factors such as size and weight contributed to the difference in real-world consumption compared to Tesla. Still, the executive noted that Xiaomi will continue to learn from the veteran EV maker.
“The Xiaomi SU7’s energy consumption performance is also very good; you can take a closer look. The fact that its test results are weaker than Tesla’s is partly due to objective reasons: the Xiaomi SU7 is a C-segment car, larger and with higher specifications, making it heavier and naturally increasing energy consumption. Of course, we will continue to learn from Tesla and further optimize its energy consumption performance!” Lei Jun wrote in a post on Weibo.
-->Lei Jun has repeatedly described Tesla as the global benchmark for EV efficiency, previously stating that Xiaomi may require three to five years to match its leadership. He has also been very supportive of FSD, even testing the system in the United States.
