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 Semi factory looks almost complete during Thanksgiving weekend
Based on recent drone videos, the Tesla Semi factory looks practically ready to start operations.
It appears that the Tesla Semi factory near Giga Nevada is already hard at work preparing for the initial production of the Class 8 all-electric truck. This was, at least, hinted at in a recent drone flyover of the facility from a longtime watcher.
The Tesla Semi factory after Thanksgiving
Drone operator and Tesla Semi advocate @HinrichsZane recently shared some footage he captured of the upcoming facility during the Thanksgiving weekend. Based on his video, it appears that Tesla gave its employees in the area the weekend off. One thing is evident from the video, however, and that is the fact that the Tesla Semi factory looks practically ready to start operations.
The Tesla Semi watcher did point out that the electric vehicle maker is still busy bringing in production equipment into the facility itself. Once these are installed, it would not be surprising if initial production of the Tesla Semi begins.
A new Tesla Semi
The upcoming completion of the Tesla Semi factory near Gigafactory Nevada seems all but inevitable in the coming months. What would be especially interesting, however, would be the vehicles that would be produced on the site. During Elon Musk’s presentation at the 2025 Annual Shareholder Meeting, a glimpse of the production Tesla Semi was shown, and it looks quite a bit different than the Class 8 all-electric truck’s classic appearance.
As could be seen in the graphic from the CEO’s presentation, the updated Tesla Semi will feature slim lightbar headlights similar to the new Tesla Model Y, Cybertruck, and the Cybercab. Tesla also teased a number of aerodynamic improvements that increased the truck’s efficiency to 1.7 kWh per mile. Extended camera units, seemingly for FSD, could also be seen in the graphic.

Tesla scores major hire as Apple scientist moves to Optimus team
Chen, who advanced from individual contributor to technical lead during his time at Apple, noted that he was blown away by Tesla’s efforts and synergy.
Former Apple research scientist Yilun Chen has left the tech giant to join Tesla’s Optimus AI team. Chen, who advanced from individual contributor to technical lead during his time at Apple, noted that he was blown away by Tesla’s efforts and synergy.
Apple veteran closes a major chapter
In a farewell note, Yilun Chen reflected on his tenure at Apple as a period defined by rapid growth and exposure to notable internal projects, some of which remain unreleased. His roles spanned engineering, research, early product incubation, and hands-on prototyping, allowing him to build expertise across both mature and emerging teams.
Chen credited mentors, colleagues, and cross-functional collaborators for shaping his trajectory, calling the experience unforgettable and emphasizing how each team taught him different lessons about scaling technology, guiding product vision, and navigating fast-moving research environments. “Each role has offered me invaluable unique lessons… My deepest gratitude goes to my colleagues, mentors and friends,” he wrote.
Tesla’s Optimus lab secured the hire
Chen said the move to Tesla was driven by the momentum surrounding Optimus, a humanoid robot powered by LLM-driven reasoning and Physical AI. After visiting Tesla’s Optimus lab, he admitted that he was “totally blown away by the scale and sophistication of the Optimus lab and deep dedication of people when I got to visit the office.”
His first week at Tesla, he noted, involved spontaneous deep-tech discussions, a flat team structure, rapid prototyping cycles, and what he called a “crazy ideas with super-fast iterations” culture. Chen emphasized that the team’s ambition, as well as its belief that humanoid robots are now within reach, creates an energy level that feels aimed at changing the world.
-->“You can feel the energy to change the world here,” he wrote in a post on social media.

Elon Musk gives nod to SpaceX’s massive, previously impossible feat
It was the booster’s 30th flight, a scenario that seemed impossible before SpaceX became a dominant force in spaceflight.
Elon Musk gave a nod to one of SpaceX’s most underrated feats today. Following the successful launch of the Transporter-15 mission, SpaceX seamlessly landed another Falcon 9 booster on a droneship in the middle of the ocean.
It was the booster’s 30th flight, a scenario that seemed impossible before SpaceX became a dominant force in spaceflight.
Elon Musk celebrates a veteran Falcon 9 booster’s feat
SpaceX completed another major milestone for its Smallsat Rideshare program on Friday, successfully launching and deploying 140 spacecraft aboard a Falcon 9 from Vandenberg Space Force Base. The mission, known as Transporter-15, lifted off two days later than planned after a scrub attributed to a ground systems issue, according to SpaceFlight Now. SpaceX confirmed that all payloads designed to separate from the rocket were deployed as planned.
The Falcon 9 used for this flight was booster B1071, one of SpaceX’s most heavily flown rockets. With its 30th mission completed, it becomes the second booster in SpaceX’s fleet to reach that milestone. B1071’s manifest includes five National Reconnaissance Office missions, NASA’s SWOT satellite, and several previous rideshare deployments, among others. Elon Musk celebrated the milestone on X, writing “30 flights of the same rocket!” in his post.
Skeptics once dismissed reusability as unfeasible
While rocket landings are routine for SpaceX today, that was not always the case. Industry veterans previously questioned whether reusable rockets could ever achieve meaningful cost savings or operational reliability, often citing the Space Shuttle’s partial reusability as evidence of failure.
-->In 2016, Orbital ATK’s Ben Goldberg argued during a panel that even if rockets could be reusable, they do not make a lot of sense. He took issue with Elon Musk’s claims at the time, Ars Technica reported, particularly when the SpaceX founder stated that fuel costs account for just a fraction of launch costs.
Goldberg noted that at most, studies showed only a 30% cost reduction for low-Earth orbit missions by using a reusable rocket. “You’re not going to get 100-fold. These numbers aren’t going to change by an order of magnitude. They’re just not. That’s the state of where we are today,” he said.
Former NASA official Dan Dumbacher, who oversaw the Space Launch System, expressed similar doubts in 2014, implying that if NASA couldn’t make full reusability viable, private firms like SpaceX faced steep odds.
