SpaceX executive talks rocket R&D: “Nobody paid us to make Falcon Heavy”
Set to give a keynote speech on October 3rd at 2018’s International Astronautical Congress (IAC), Hans Koenigsmann – SpaceX Vice President of Build and Flight Reliability – attended an impromptu talk one day prior, titled “From the University of Bremen to SpaceX”.
Speaking before a small audience, the University of Bremen graduate and fourth employee to join SpaceX discussed his opinions of Falcon Heavy, BFR, and more, frankly relating how SpaceX intentionally chose to build Falcon Heavy on its own, going so far as to turn down funding reportedly offered by one or more US government agencies.

From Bremen to SpaceX (to Bremen)
Hopefully a sign of things to come for his 09:20 UTC, Oct. 3 keynote, titled “Reusability: The Key to Reliability and Affordability”, Hans’ precursor talk centered around the circuitous path that led him from University of Bremen to SpaceX, humorously describing how he “got bored of airplanes pretty quickly” after becoming an aerospace engineer. He quickly turned to space, hopping between a number of German smallsat projects that eventually led him to settle in the U.S. after flying there and back “at least 25 times”.
Once in the US, he wound up working at spaceflight startup Microcosm – alongside now-president and COO of SpaceX Gwynne Shotwell – for several years before running into Elon Musk and almost immediately accepting the eccentric entrepreneur’s SpaceX job offer in 2002. He has worked for SpaceX ever since and now spends a majority of his time managing and overseeing its BFR, Block 5, and Crew Dragon programs with a focus on systematically ensuring reliability. He touched on the company’s BFR development program and pointed to the fabrication of massive composite structures as the single most pressing challenge facing SpaceX engineers and technicians.
Asked by an audience member about the apparent difficulty of developing the heat-shield segment of BFR’s spaceship upper stage (BFS), Koenigsmann was quite confident that it would be a relatively easy aspect of the craft’s development, making the argument that what really matters to the craft is overall heat transfer per unit of its shield. From a basic comparison of the area of a given heat shield and the spacecraft’s mass at reentry, his lack of concern is probably warranted – a BFR spaceship’s worst-case LEO reentry is likely to be less stressful than an average Space Shuttle reentry.

“Try [to not] get money from the government”
Perhaps most intriguing of all Koenigsmann’s comments was an almost unprovoked segue into the US government’s involvement in Falcon Heavy development. According to the SpaceX executive, the company was actually approached by “the government”, with the unknown agency or agencies stating – in Hans’ words – that they wanted to be a part of the rocket’s development. According to Hans, SpaceX responded in an extremely unorthodox fashion: “we said, ‘Nope! We just wanna build it, you can buy it when it’s ready and we’ll charge you for the service.’” He noted in the next sentence that funding was the primary lever on the table:
“It’s a great position to do this, you gotta find the money, you gotta know people that have money and are willing to invest in your company, and [SpaceX has] been lucky enough to know some of those people.”
In other words, when given an opportunity to either rely on government funding or some other source of capital for a given R&D project, SpaceX – or at least Hans Koenigsmann, VP of Reliability – would apparently recommend the latter option in almost all cases. Again, without being prompted, he elaborated on his feelings about funding sources, culminating in a statement that is simply profound coming from an executive in the aerospace industry. The following quote is unabridged and straight from Hans himself:
“You need to [try to not] get money from the government, otherwise the government will tell you what to build and how to build it… they will tell you how to build this and that’s just not always – I mean for some things it’s the best to do, but in others it’s actually not.”

- The first spaceworthy Crew Dragon capsule is already in Florida, preparing for its November 2018 launch debut. The same capsule will be refurbished and reflown as few as three months after recovery. (SpaceX)
- It’s currently unclear whether B1046 or B1048 will become the first SpaceX rocket to fly three times. (Tom Cross)
This sentiment could suggest that SpaceX will seek to prioritize private funding sources for the development of future vehicles like BFR’s rocket and spaceship, although there is plenty of room for interpretation in Hans’ IAC 2018 comments. SpaceX currently maintains strong and productive relationships with both NASA and the USAF, primarily centered around the company’s $2.6B fixed-price contract for the development and operation of Crew Dragon.

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.
