Congress warned of delays to SpaceX and Boeing manned missions
The Government Accountability Office issued a report to Congress in which it warned legislators there is a strong likelihood neither SpaceX nor Boeing will be ready to fly astronauts to the International Space Station prior to 2019. Both had originally planned to begin crewed ISS missions in 2018. Because of the delay, the GAO is advising NASA to come up with backup plans for transporting astronauts to and from the ISS after 2018.
At present, the only transportation available is aboard a Russian Soyuz rocket, for which the fee is $80 million per person. NASA has already booked the seats it needs through the end of 2018 but the GAO report means it will need to start reserving seats for 2019 as well. It takes three years to complete the booking process, so there is no time to lose.
If SpaceX or Boeing can’t provide space transportation by then, NASA could be faced with a period of time when it has no way to get people up to the ISS or return them to earth. “Without a viable contingency option for ensuring uninterrupted access to the ISS in the event of further Commercial Crew delays, NASA risks not being able to maximize the return on its multibillion dollar investment in the space station,” the GAO report states. NASA says it is in agreement with the report’s findings and that it will have a contingency plan in place by March 13.
The problems for SpaceX center on changes to the Falcon 9 rocket that are underway. Known by the name of Block 5, the upgrades involve five major changes to the rockets. The Verge reports that the GAO is concerned those changes will not be completed and verified by NASA in time for the proposed first unmanned flight of the Dragon space capsule scheduled for later this year. In addition, SpaceX is working to allay fears about cracking in turbine blades that NASA claims constitute an “unacceptable risk” for crewed missions.
Boeing’s troubles are partly centered on the fact that its Atlas V rocket uses Russian made engines. Russia and the United States are not enjoying the warmest of relationships at the moment and NASA is having difficulty getting the information it needs to verify the engines are safe for crewed missions. Boeing is also behind in testing the parachute recovery system for is CST-100 Starliner space capsule.
In the report, the GAO sets forth the complex requirements involved in certifying that a spacecraft is safe for human travelers.
“Before a company’s crew transportation system can be certified by NASA, it must meet two sets of requirements. The ISS program levies a set of 332 requirements that must be met by all visiting spacecraft, whether they are carrying cargo or crew to the station. There are three major areas outlined in the ISS requirements document: 1) interface requirements for both the ISS and the spacecraft; 2) performance requirements for ground systems supporting the spacecraft; and 3) design requirements for spacecraft to ensure safe integration with the ISS.”
In September, 2014, NASA awarded two contracts for Commercial Crew Transportation development — $4.2 billion to Boeing and $2.6 billion to SpaceX. The need for the United States to be able to deliver and retrieve ISS crew members is urgent but urgency cannot be allowed to overrule safety. Perhaps SpaceX or Boeing will make progress faster than the GAO expects and everyone will be able to breath a sigh of relief. Until then, the pressure to complete testing and obtain all necessary certifications is, and will remain, intense. The ISS is expected to remain operational until 2024.

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.
