SpaceX Mars landing expert talks Starship recovery challenges in new interview
Formerly responsible for developing Falcon 9 (and Heavy) into the routinely-landing reusable rocket it is today, senior SpaceX engineer Lars Blackmore says he now has one primary focus: figuring out how to land Starship on Earth, the Moon, and Mars.
A graduate of University of Cambridge and MIT, the latter of which interviewed him on October 23rd for an “Alumni Stories” blog, Lars Blackmore has become famous for his groundbreaking work in guidance, navigation, and control (GNC). After graduating with honors from Cambridge and earning a PhD from MIT, Dr. Blackmore joined NASA in 2007 and immersed himself in “precision Mars landing”, part of a more general focus on figuring out how to autonomously control vehicles in uncertain conditions.
In his last year at NASA, Blackmore co-invented an algorithm known as G-FOLD (Guidance for Fuel Optimal Large Divert) that should theoretically enable precision landings on Mars, improving the state of the art by two full orders of magnitude (+/- 10 km to +/- 100 m). In 2011, he departed NASA and joined SpaceX, where he lead the development of the GNC technology needed to successfully and reliably recovery Falcon 9 boosters. Although the same could be said for any number of critical, groundbreaking systems that had to be developed, the onboard software that autonomously guides Falcon 9 landings on the fly is one of many things that booster recovery and reuse would be wholly impossible without.
After numerous failed attempts, all part SpaceX’s preferred learning process, Falcon 9 successfully landed for the first time on December 21st, 2015. As they say, the rest is history: in the roughly four years since that milestone landing, SpaceX has successfully completed 57 orbital launches, recovered boosters 43 more times, and reused flight-proven boosters on 23 launches. Since that first success, more than half of all SpaceX launches have been followed by a successful booster landing (or two).

Back to Mars
In 2018, Dr. Blackmore officially took on a new full-time role as SpaceX’s Principal Mars Landing Engineer. As the namesake suggests, this meant handing (now semi-routine) Falcon 9 and Heavy GNC development to a strong team and beginning to tackle an array of new problems that will need to be solved for SpaceX to reach the Moon, Mars, and beyond.
Following radical design modifications made to Starship in 2018 and again in 2019, SpaceX is pursuing a radically different method of recovery with Starship (the upper stage), while Super Heavy will more directly follow in the footsteps of Falcon 9/Heavy. Starship, however, is being designed to perform a guided descent more akin to a skydiver falling straight down, using flaps at its nose and tail (explicitly “not wings”) to accurately guide its fall.
As little as a few hundred meters above the ground, Starship will then perform a radical maneuver, igniting its Raptor engines to flip around, burn in the opposite direction to counteract that sideways boost, and finally coming in for a precise landing on Earth/Mars/the Moon.
Beyond the new GNC software and knowledge needed to make that maneuver real, Blackmore is also responsible for Starship atmospheric entry, no less critical to enabling precise, repeatable landings from orbital velocity to touchdown. In his recent interview with University of Cambridge staff, Lars revealed that his role as Principal Mars Landing Engineer involved a far wider scope than his previous GNC-centered work, with the goal instead being to design a launch vehicle (Starship) from the ground up to be easily recovered and reused. Falcon 9 Block 5 may be radically different than the ‘V1.0’ rocket that debuted in 2010, but it’s still ultimately a product of retroactive engineering.
With Starship and Super Heavy, SpaceX instead wants to take the vast wealth of knowledge and experience gained from F9/FH and build the vehicle from the ground up to be optimized for full reuse. Ultimately, Dr. Blackmore stated that “landing Starship will be much harder than landing Falcon 9, but if [SpaceX] can do it, it will be revolutionary.”

Elon Musk confirms Tesla Cybercab pricing and consumer release date
Elon Musk has confirmed that Tesla does intend to sell a version of the Cybercab for less than $30,000 by 2027.
Elon Musk has confirmed that Tesla does intend to sell a version of the Cybercab for less than $30,000 by 2027. He shared the update in a post on social media platform X.
Amidst Tesla’s announcement that the first Cybercab has been produced at Giga Texas’ production line, some members of the Tesla community immediately started joking about how the milestone will affect a wager shared by popular YouTube tech reviewer Marques Brownlee (MKBHD.)
Following Tesla’s We, Robot event in October 2024, MKBHD noted that while the Cybercab was impressive in a lot of ways, he is very skeptical about Elon Musk’s estimate that the autonomous two-seater could be sold to consumers for below $30,000 around 2027.
“I think the obvious red flag, the biggest red flag to me is the timeline stuff. This is notorious Elon stuff. He gets on stage, he says we’re going to have this vehicle out for $30,000 before 2027,” he said, adding “No, they’re not. There’s just no way that they’re actually going to be able to do that. I mean, if they do, let’s say they do, I will shave my head on camera because I’m that confident.”
It was then no surprise that meme images of MKBHD with his head shaved immediately spread on X following Tesla’s announcement that the first Cybercab has been built at Giga Texas. One of these, which was posted by longtime FSD tester Whole Mars Catalog, received a response from Elon Musk. The CEO responded with the words “Gonna happen,” together with a laughing emoji.
Apart from riding jokes about MKBHD’s wager, Musk also confirmed that Tesla will be selling a Cybercab to regular consumers before 2027, and the vehicle will be priced for $30,000 or less. In response to an X user who asked if the exact scenario will be happening, Musk responded with a simple “Yes.”
While the first Cybercab has been produced at Giga Texas, it would not be surprising if the following months will only see low volumes of the autonomous two seater being produced. As per Elon Musk in previous comments, the Cybercab’s early production will likely be slow, but it will eventually be extremely fast. “For Cybercab and Optimus, almost everything is new, so the early production rate will be agonizingly slow, but eventually end up being insanely fast,” he said.

First Tesla Cybercab rolls off Giga Texas production line
Tesla’s official account on X shared an image showing employees gathered around the first Cybercab built at Gigafactory Texas.
Tesla has produced the first Tesla Cybercab at Texas Gigafactory, marking a key milestone ahead of the planned autonomous two-seater’s production in April. The two-seat Robotaxi, which was unveiled in 2024, is designed without pedals or a steering wheel and represents Tesla’s most aggressive step yet toward fully autonomous mobility.
Tesla’s official account on X shared an image showing employees gathered around the first Cybercab built at Gigafactory Texas. Elon Musk echoed the milestone, writing, “Congratulations to the Tesla team on making the first production Cybercab!”
Previous comments from Musk on X reiterated the idea that production of the Cybercab “starts in April.” The vehicle will launch without traditional driver controls, and it will rely entirely on Tesla’s vision-based Full Self-Driving (FSD) system.
The Cybercab is positioned to compete with autonomous services such as Waymo. While Tesla has deployed Model Y vehicles in limited Robotaxi operations in Austin and the Bay Area, a serious ramp of the service to other cities across the United States is yet to be implemented. The production of the Cybercab could then be seen as a push towards the company’s autonomy plans.
Musk has linked the Cybercab to Tesla’s proposed “Unboxed” manufacturing process, which would assemble large vehicle modules separately before integrating them, rather than following a traditional production line. The approach is intended to cut costs, reduce factory footprint, and speed up output.
That being said, Elon Musk has set expectations for the Cybercab’s production ramp. As per Musk, it would likely take some time before meaningful volumes of the Cybercab are produced because it is such a new and different vehicle. But when the vehicle hits its pace, volumes will be notable.
“Initial production is always very slow and follows an S-curve. The speed of production ramp is inversely proportionate to how many new parts and steps there are. For Cybercab and Optimus, almost everything is new, so the early production rate will be agonizingly slow, but eventually end up being insanely fast,” Musk noted.

California city weighs banning Elon Musk companies like Tesla and SpaceX
A resolution draft titled, “Resolution Ending Engagement With Elon Musk-Controlled Companies and To Encourage CalPERS To Divest Stock In These Companies,” alleges that Musk “has engaged in business practices that are alleged to include violations of labor laws, environmental regulations, workplace safety standards, and regulatory noncompliance.”
A California City Council is planning to weigh whether it would adopt a resolution that would place a ban on its engagement with Elon Musk companies, like Tesla and SpaceX.
The City of Davis, California, will have its City Council weigh a new proposal that would adopt a resolution “to divest from companies owned and/or controlled by Elon Musk.”
This would include a divestment proposal to encourage CalPERS, the California Public Employees Retirement System, to divest from stock in any Musk company.
A resolution draft titled, “Resolution Ending Engagement With Elon Musk-Controlled Companies and To Encourage CalPERS To Divest Stock In These Companies,” alleges that Musk “has engaged in business practices that are alleged to include violations of labor laws, environmental regulations, workplace safety standards, and regulatory noncompliance.”
It claims that Musk “has used his influence and corporate platforms to promote political ideologies and activities that threaten democratic norms and institutions, including campaign finance activities that raise ethical and legal concerns.”
If adopted, Davis would bar the city from entering into any new contracts or purchasing agreements with any company owned or controlled by Elon Musk. It also says it will not consider utilizing Tesla Robotaxis.

A staff report on the proposal claims there is “no immediate budgetary impact.” However, a move like this would only impact its residents, especially with Tesla, as the Supercharger Network is open to all electric vehicle manufacturers. It is also extremely reliable and widespread.
Regarding the divestment request to CalPERS, it would not be surprising to see the firm make the move. Although it voted against Musk’s compensation package last year, the firm has no issue continuing to make money off of Tesla’s performance on Wall Street.
The decision to avoid Musk companies will be considered this evening at the City Council meeting.
The report comes from Davis Vanguard.
It is no secret that Musk’s political involvement, especially during the most recent Presidential Election, ruffled some feathers. Other cities considered similar options, like the City of Baltimore, which “decided to go in another direction” after awarding Tesla a $5 million contract for a fleet of EVs for city employees.
