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.”

Tesla just made Service even easier and more convenient

The new feature is rolling out to iOS users now; we have not heard any confirmation from Android phone users whether they are receiving it too.

Tesla just made servicing your vehicle even easier and more convenient than it already is.

All it did was add a new section to its smartphone app.

Tesla has officially launched a new Maintenance tab that estimates the repair date and cost, and uses vehicle data to determine if any part is in need of replacement.

It can be found by accessing the app, going to Service, then hitting Request Service, and then Maintenance.

The new feature is rolling out to iOS users now; we have not heard any confirmation from Android phone users whether they are receiving it too. Since it is not a vehicle capability, we do not believe Tesla will delay the release of the feature to Android phones.

Teslas are already well known for having extremely low maintenance needs, and semi-annual check ups usually only require a tire rotation and some additional windshield washer fluid. There is not a need for things like oil changes or other things that are routinely needed on combustion engine cars due to the lack of parts.

Additionally, the small addition to the company’s smartphone app will help facilitate needs for Service, and could help relieve some congestion, while also streamlining the repair process for technicians.

Tesla to make app change for easier communication following Service

One of the biggest complaints about owning a Tesla is Service wait times, as availability can be extremely limited in some areas. However, Tesla has done a lot to work on increasing the number of Service centers it has, while also working hard to streamline service and make it less time-consuming.

Tesla has aimed to have an F1-style service experience, but it has not worked out that way. With that being said, there are significantly fewer complaints with Tesla’s Service division than in years past. With the presence of Mobile Technicians and more refined Service processes, things are definitely improving.

Elon Musk hits back at former Tesla employee who disagrees with pay package

Tesla is worth more than all other automotive companies combined. Which of those CEOs would you like to run Tesla?

It won’t be me.

Elon Musk gave a tough response to a former Tesla employee who spoke out on X about the structure of the CEO’s pay package, arguing that it is an overpayment and would not generate enough shareholder value.

Without a doubt, the biggest issue on the bill at this year’s Tesla Shareholder Meeting in November is that of the pay package that was proposed to CEO Elon Musk.

As the Shareholder Meeting approaches, Tesla is urging those investors to vote in support of Musk’s pay package. So far, the community has been overwhelmingly supportive of giving Musk his massive payday, which could give him $1 trillion in additional holdings if he completes each of the outlined performance tranches.

However, there are a handful of institutional and individual shareholders who have pushed back against the package, either because of its value or because they feel it does not benefit shareholders enough.

Last week, we reported that Institutional Shareholder Services (ISS) advised voting against Tesla’s pay package for Musk. The firm said the payday would give Musk”extraordinarily high pay opportunities over the next ten years,” and it would “reduce the board’s ability to meaningfully adjust future pay levels.”

Tesla CEO Elon Musk’s $1 trillion pay package hits first adversity from proxy firm

Additionally, it called the value of the pay package “astronomical.”

On Saturday, a former Tesla employee said on X that Tesla’s proposed pay package for Musk would “barely beat inflation and it would underperform the S&P 500 considerably.” Additionally, he said:

“Sorry, Tesla, some of us (and supposedly, ISS too) simply don’t think that underperforming the S&P 500 this much is worth paying somebody 20 billion dollars worth of company value.

As a fan, I love Tesla, I want it to succeed. As a shareholder, I don’t want Tesla to over-pay for its CEO I strongly believe that the 2025 pay package proposal would over-pay for its CEO, and that other competent CEOs could grow Tesla just as much with way less political drama and cost investors much less that this proposal.”

Musk responded bluntly:

“Tesla is worth more than all other automotive companies combined. Which of those CEOs would you like to run Tesla? It won’t be me.”

It seems the worry about Musk’s potential involvement in politics still looms to many, based on the responses to Musk’s post, which frequently mention that as a downside of his last year as Tesla CEO. However, Tesla’s Board confronted that directly.

In its proxy filing after announcing the pay package, Tesla said that it had three commitments, one of which was that the company would “receive assurances that Musk’s involvement with the political sphere would wind down in a timely manner.”

Musk’s previous pay package was approved by shareholders twice, but it never made it to the CEO because of a lawsuit with the Delaware Chancery Court brought forth by a small-time shareholder.

The response from Musk does seem to show that if this time is no different, he will inevitably step down as CEO in the coming years.

Tesla rivals are lagging behind alarmingly in this crucial EV necessity

Tesla rivals are lagging behind the company in alarming fashion in this crucial EV necessity: charging.

Tesla has had a long-standing reputation for having the most expansive electric vehicle charging infrastructure, and even as other companies have launched their own as part of the vehicle manufacturing, nobody seems to keep pace with the EV leader.

A report from Paren exhibited this trend in Q3, showing that Tesla overwhelmingly dominated EV charging stall installations over the past three months. This data is based on U.S. installations, where Tesla has long held a dominating position as the leader in overall electric vehicle sales for many years.

In Q3, Tesla installed 1,820 new chargers in the United States, bringing its total presence to 34,328, an all-time market share of 53.2 percent of all charging stalls in the country.

What’s alarming is the fact that all other networks — ChargePoint, Red E, Electrify America, EV Connect, EVgo, Ionna, Blink, Pilot Flying J, and Rivian Adventure — only installed 841 chargers collectively in Q3. That is nearly 1,000 units behind Tesla, despite there being nine companies contributing as competitors.

These nine networks have 10,055 stalls in total, the data from Paren shows, accounting for 15.6 percent of the chargers in the United States.

EV charging is such a crucial part of the ownership experience, and also a part of the ongoing expansion of EV adoption in the United States.

As more people buy EVs and they become a more prominent form of passenger transportation, more chargers are needed. Many owners charge at home, but charging options in public are important to have for traveling, commuting, and for those who do not have access to residential charging.

Tesla ownership without home charging: Here’s how it’s done

With Tesla opening its Supercharger Network to the majority of EV brands over the past two years, things have gotten better.

It has been alarming to see so many companies involved in EV infrastructure essentially accept the gap between Tesla and themselves; not a single company has tried to up its pace to catch up to what Tesla has.

When it comes down to it, as long as there is charging, the manufacturer does not truly matter.

However, it would be nice to see Tesla have some competition in the space, but with its domination and head start in the infrastructure division, it seems the company will have this competitive advantage for years to come.
