SpaceX schedules first Falcon Heavy launch in two years in early October
For the first time in more than two years, SpaceX has a firm launch date for its next Falcon Heavy mission: October 9th, 2021.
Revealed on September 7th as part of a US Space Systems Command presentation at the 2021 Small Payload Ride Share Symposium, October 9th now appears to be the military’s official target date for SpaceX’s fourth Falcon Heavy launch ever. Currently the most powerful and capable commercial rocket in operation and likely to remain so – perhaps alongside Starship – for years to come, Falcon Heavy debuted in February 2018, successfully delivering a mock payload into interplanetary space.
After another 14 months of work, SpaceX then debuted Falcon Heavy Block 5 – an upgraded version of the rocket that took advantage of all of Block 5’s reusability, reliability, and performance improvements. Just two months after Falcon Heavy Block 5’s inaugural April 2019 launch, SpaceX launched the rocket for the third time, supporting a US Air Force rideshare mission, reusing both of Flight 2’s side boosters, and giving the US military a firsthand demonstration of the rocket’s capabilities. However, Falcon Heavy has not flown once since then.
For mostly unknown reasons, Falcon Heavy’s fourth launch – a US military mission known as USSF-44 (formerly AFSPC-44) – has gradually slipped from a late-2020 target to Q1, Q2, Q3, and finally Q4 (October) 2021. SpaceX only began qualifying USSF-44’s Falcon Heavy boosters at its McGregor, Texas test facilities in late September 2020, a few weeks after delays from late-2020 to February 2021 and June 2021 were quietly announced. At that point, the US was deep into the throes of the COVID-19 pandemic’s local peak.
Only in May 2021 did the US military finally directly address major USSF-44 and USSF-52 delays, blaming them on “payload readiness.” Given that the Space Force never blamed SpaceX or rocket availability for what is likely to be a full year of launch delays, the implication is that likely satellite manufacturers Northrop Grumman, Lockheed Martin, Maxar, or Boeing have run into major technical issues. It’s also possible that those payload-side delays have been caused by a combination of supply chain issues and constraints brought on by the ongoing global pandemic.
-->Meanwhile, USSF-44’s all-new Falcon Heavy rocket appears to have been at Cape Canaveral and more or less ready for flight since Q2 2021 and SpaceX has been hard at work qualifying at least two more Falcon Heavy center cores for at least two additional missions scheduled in H1 2022.
Scheduled to launch no earlier than (NET) October 9th, Falcon Heavy #4 will likely roll out to Kennedy Space Center Pad 39A around 5-7 days prior for a crucial static fire test and pad shakedown. SpaceX is currently scheduled to launch Crew Dragon’s all-private Inspiration4 mission as early as September 14th, giving the company around three weeks to modify Pad 39A and its transporter/erector, gather all four USSF-44 Falcon Heavy stages, and assemble the rocket. Another Crew Dragon mission is then scheduled to launch as early as October 31st, again leaving SpaceX less than three weeks to reconfigure Pad 39A.
Successfully completing that back-to-back-to-back Dragon-FH-Dragon manifest on schedule will be a significant challenge and delays are probably more likely than not. Nevertheless, Falcon Heavy will likely roll out to the launch pad for the first time in more than two years less than a month from today.

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.
