Musk sets a date for Starship trip to Mars with Optimus on board
Optimus could be the first humanoid to make it to Mars, and Musk has set a date for when he thinks it’ll happen.
Elon Musk has shared when he expects to take Starship to Mars for its first uncrewed mission, and he also says Tesla’s Optimus humanoid robot will be on board for the flight.
On Friday, Musk wrote on X that SpaceX’s reusable Starship rocket will take Optimus to Mars at the end of 2026, with human landings expected to commence a few years later.
“Starship departs for Mars at the end of next year, carrying Optimus,” Musk said. “If those landings go well, then human landings may start as soon as 2029, although 2031 is more likely.”

Last year, the SpaceX and Tesla head also said he expected that SpaceX would be able to begin uncrewed launches in 2016, with early launches including both Optimus and a Cybertruck unit.
Musk also followed up the announcement with a post on X on Saturday morning, noting that he expects SpaceX to launch more than 90 percent of Earth’s payload mass to orbit this year. Meanwhile, he says China will make up just around 5 percent, while the rest of the world, including other parts of America, would also make up just 5 percent.
He also predicted that the number would go up even further to nearly 100 percent, once SpaceX’s reusable rocket is being launched more frequently.
“When Starship is launching at high rate, SpaceX will probably carry >99 percent of Earth’s payload mass to orbit. This is necessary to make Mars a self-sustaining civilization,” Musk added.

To be sure, Musk has been known to make ambitious claims about when his companies’ products would achieve certain milestones. For example, Musk predicted in 2018 that SpaceX could launch a rocket to Mars with humans aboard by 2024, though SpaceX only began testing the company’s reusable Starship in 2023.
Still, the company has been routinely testing Starship since then, and with increasing frequency, and in October, SpaceX performed the first catch of the Starship’s Super Heavy booster after liftoff to demonstrate the concept that a reusable rocket could be possible. In a launch earlier this month, SpaceX again successfully caught the Super Heavy Booster, though it lost the upper stage to a “rapid unscheduled disassembly,” effectively meaning that it had exploded in air and showered surrounding areas with rocket parts.
The explosion was the second consecutive launch in which debris from Starship reigned down, highlighting the continued importance of testing as SpaceX aims to make the rocket a viable product for reusable space travel.
On Friday, SpaceX also launched its Crew Dragon spacecraft to the International Space Station (ISS) to rescue astronauts that have been stuck on the orbital craft, after a Boeing Starliner craft was originally intended to bring them back to Earth. While SpaceX attempted to rescue the two astronauts in September, issues with the Crew Dragon craft’s thrusters discovered upon arrival made NASA hold off on approving the return mission.
Update 3/16/25: Edited final paragraph after incorrectly saying that Starliner had been a SpaceX craft, rather than one owned by Boeing.

Tesla Cybercab display highlights interior wizardry in the small two-seater
Photos and videos of the production Cybercab were shared in posts on social media platform X.
The Tesla Cybercab is currently on display at the U.S. Department of Transportation in Washington, D.C., and observations of the production vehicle are highlighting some of its notable design details.
Photos and videos of the production Cybercab were shared in posts on social media platform X.
Observers of the Cybercab display unit noted that the two-seat Robotaxi provides unusually generous legroom for a vehicle of its size. Based on the vehicle’s video, the compact two-seater appears to offer more legroom than Tesla’s larger vehicles such as the Model Y, Model X, and Cybertruck.
The Cybercab’s layout allows Tesla to dedicate nearly the entire cabin to passengers. The vehicle is designed without a steering wheel or pedals, which helps maximize interior space.
Footage from the display also highlights the Cybercab’s large center screen, which is positioned prominently in front of the passenger bench. The display appears intended to provide entertainment and ride information while the vehicle operates autonomously.
Images of the vehicle also show an additional camera integrated into the Cybercab’s C-pillar. The extra camera appears to expand the vehicle’s field of view, which would be useful as Tesla works toward fully unsupervised Full Self-Driving.
Tesla engineers have previously explained that the Cybercab was designed to be highly efficient both in manufacturing and in operation. Cybercab Lead Engineer Eric E. stated in 2024 that the Robotaxi would be built with roughly half the number of parts used in a Model 3 sedan.
“Two seats unlocks a lot of opportunity aerodynamically. It also means we cut the part count of Cybercab down by a substantial margin. We’re gonna be delivering a car that has roughly half the parts of Model 3 today,” the Tesla engineer said.
The Tesla engineer also noted that the Cybercab’s cargo area can accommodate multiple golf bags, two carry-on suitcases, and two full-size checked bags. The trunk can also fit certain bicycles and a foldable wheelchair depending on size, which is quite impressive for a small car like the Cybercab.

Elon Musk’s xAI wins permit for power plant supporting AI data centers
The development was reported by CNBC, citing confirmation from the Mississippi Department of Environmental Quality (MDEQ).
Mississippi regulators have approved a permit allowing Elon Musk’s artificial intelligence company xAI to construct a natural gas power plant in Southaven. The facility is expected to support the company’s expanding AI infrastructure tied to its Colossus data center operations near Memphis.
The development was reported by CNBC, citing confirmation from the Mississippi Department of Environmental Quality (MDEQ).
According to the report, regulators “voted to approve the permit” of xAI subsidiary MZX Tech LLC to construct a power plant featuring 41 natural gas-burning turbines “after careful consideration of all public comments and community concerns.”
The Mississippi Department of Environmental Quality stated that the permit followed a regulatory review process that included public comments and community input. Jaricus Whitlock, air division chief for the MDEQ, stated that the project met all applicable environmental standards.
“The proposed PSD permit in front of the board today not only meets all state and federal permitting regulations, but goes above and beyond what is required by law. MDEQ and the EPA agree that not a single person around our facilities will be exposed to unhealthy levels of air pollution,” Whitlock stated.
The planned facility will help provide electricity for xAI’s AI computing infrastructure in the Memphis region.
The Southaven project forms part of xAI’s efforts to scale computing capacity for its artificial intelligence systems.
The company currently operates two major data centers in Memphis, known as Colossus 1 and Colossus 2, which provide computing power for xAI’s Grok AI models. xAI is also planning to build another large data center in Southaven called Macrohardrr, which would be located in a warehouse previously used by GXO Logistics.
Large-scale AI training requires substantial computing power and electricity, prompting technology companies to develop dedicated energy infrastructure for their data centers.
SpaceX President Gwynne Shotwell previously stated that xAI plans to develop 1.2 gigawatts of power capacity for its Memphis-area AI supercomputer site as part of the federal government’s Ratepayer Protection Pledge. The commitment was announced during an event with United States President Donald Trump.
“As part of today’s commitment, we will take extensive additional steps to continue to reduce the costs of electricity for our neighbors. xAI will therefore commit to develop 1.2 GW of power as our supercomputer’s primary power source. That will be for every additional data center as well. We will expand what is already the largest global Megapack power installation in the world,” Shotwell said.
“The installation will provide enough backup power to power the city of Memphis, and more than sufficient energy to power the town of Southaven, Mississippi where the data center resides. We will build new substations and invest in electrical infrastructure to provide stability to the area’s grid.”

Tesla China teases Optimus robot’s human-looking next-gen hands
The image was shared by Tesla AI’s account on Weibo and later reposted by Tesla community members on X.
A new teaser shared by Tesla’s China team appears to show a pair of unusually human-like hands for Optimus.
The image was shared by Tesla AI’s account on Weibo and later reposted by Tesla community members on X.
As could be seen in the teaser image, the new version of Optimus’ hands features proportions and finger structures that look strikingly similar to those of a human hand. Their appearance suggests that they might have dexterity approaching that of a human hand.
If the image reflects a new generation of Optimus’ hands, it could indicate Tesla is continuing to refine one of the most critical components of its humanoid robot.
Hands are widely viewed as one of the most difficult engineering challenges in robotics. For Optimus to perform complex real-world work, from manufacturing tasks to household activities, its hands would need to be the best in the industry.
Elon Musk has repeatedly described Optimus as Tesla’s most important long-term product. In posts on social media platform X, Musk has stated that Optimus could eventually become the first real-world Von Neumann machine.
In theory, a Von Neumann machine is a self-replicating system capable of building copies of itself using available materials. The concept was originally proposed by mathematician John von Neumann in the mid-20th century.
“Optimus will be the first Von Neumann machine, capable of building civilization by itself on any viable planet,” Musk wrote in a post on X.
If Optimus is expected to carry out complex work autonomously in the future, high levels of dexterity will likely be essential. This makes the development of advanced robotic hands a key step towards Musk’s long-term expectations for the product.
