SpaceX accepts delivery of NASA’s DART asteroid impact spacecraft
NASA says that the Double Asteroid Redirect Test (DART) spacecraft has arrived at SpaceX’s Vandenberg Space Force Base (VSFB) facilities for a launch later this month.
After being carefully packaged for shipment from Maryland’s Johns Hopkins University Applied Physics Lab (JHUAPL) on September 29th, the small 690 kg (~1500 lb) spacecraft was transported by road and arrived at third-party VSFB processing facilities on October 2nd. Once there, technicians unpacked DART, charged its batteries, and performed a wide range of final tests and checkouts to verify the nominal operation of all spacecraft systems after an almost three-thousand-mile journey.
On October 26th, the spacecraft was once again prepared for transport, this time traveling just a few miles from Asrtotech’s to SpaceX’s payload processing facilities (PPF). Colocated inside the company’s main Space Launch Complex 4 (SLC-4) hangar, where DART’s reused Falcon 9 rocket is also preparing for flight, the NASA spacecraft is now just a fraction of a mile away from where it will soon take flight.
At SpaceX’s PPF, DART will be fueled with toxic hydrazine propellant for its attitude control thrusters and (likely but unconfirmed) xenon propellant for its main ion thruster propulsion system Engineers and technicians will also perform final closeout work, removing protective covers, unlatching and priming mechanical systems, and generally preparing the spacecraft for launch.
Around 7-10 days prior to NASA’s current 10:20 pm PST, Nov 23 (05:20 UTC, Nov 24) launch date, SpaceX will encapsulate DART and its Italian-built LICIACube smallsat companion inside Falcon 9’s payload fairing, which will dwarf the relatively tiny duo.

Sans fairing and DART, twice-flown Falcon 9 booster B1063 and a new expendable upper stage will likely roll out to SLC-4E for the first time around November 16th to complete a prelaunch wet dress rehearsal and static fire test. Falcon 9 will then return to the hangar, where SpaceX will install its payload fairing with DART safely cocooned inside. Barring surprises, the fully integrated rocket will then roll out to the pad for the last time a few days prior to launch.
Despite the small payload and indications from public NASA and SpaceX data that Falcon 9 is more than capable of a return-to-launch-site landing after launching a spacecraft ~50% heavier than DART, Falcon 9 B1063 will reportedly land downrange on drone ship Of Course I Still Love You (OCISLY). Regardless, DART will be the first interplanetary NASA payload launched on a flight-proven commercial rocket and Falcon 9’s first interplanetary launch ever (excluding TESS and DSCOVR, which technically remain under the gravitational influence of the Earth-Moon system).

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.

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.
