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 rival’s CEO makes shock suggestion to customers about Model Y

“The Model Y is a great car, and Tesla also announced a number of promotions yesterday, so you might want to consider it.”

Tesla rival Xiaomi is experiencing demand that is off-the-charts with its new YU7 crossover, which competes with the Model Y. The company’s CEO has stated that demand is truly outpacing what it can build, and that customers in limbo should consider the Model Y because “it’s a great car.”

The Xiaomi YU7 has already gained an incredible number of orders so far. Its launch a few months ago had consumers busting down doors to place an order before others, and demand has been so high that customers will wait, on average, between 56 and 59 weeks for delivery.

Tesla Model Y meets new competition from Xiaomi 

Within 18 hours, Xiaomi received about 240,000 orders, CarScoops reported. Some customers are truly interested in the vehicle, but cannot wait the extended period to take delivery as they might need a car now.

Xiaomi CEO Lei Jun said on social meida that there are other cars out there that would be suitable as a replacement to the YU7:

“If you need to buy a car quickly, other China-produced new energy vehicles are pretty good.”

He explicitly mentioned the Model Y, Xpeng G7, and Li Auto i8.

Regarding the Model Y, he said:

“The Model Y is a great car, and Tesla also announced a number of promotions yesterday, so you might want to consider it.”

The Model Y has been the best-selling car in the world over the past two years, and it still leads in many markets as the most sought-after EV. However, in China, there are so many formidable competitors that customers are seemingly going for whatever they can get to first.

Of course, a car is a car, but Tesla has gained a more notable reputation for its industry-leading tech and driver assistance systems, including City Autopilot, which has been used in China for a few months now.

Tesla offers tasty Supercharging incentive as Q3 push continues

Tesla is offering a tasty Supercharging incentive on inventory Model 3 units in Canada as it continues to push sales in the third quarter.

In the United States, Tesla is preparing for the end of the $7,500 electric vehicle tax credit. While it is offering a multitude of incentives in the U.S. to help push sales of its vehicles before the credit goes away, it is not saving the deals for Americans exclusively.

Yesterday, the company announced it is now offering Free Supercharging for life on all Model 3 inventory in Canada, a massive incentive for those who would use the vehicle as a daily driver:

The deal would normally only apply to Superchargers located in Canada, meaning if a Canadian drove over the border into the United States and Supercharged, they would have to pay for it.

However, Tesla also confirmed that the charging deal would extend to the U.S. Canadians will be able to drive across the U.S. and Supercharge for free for the life of the vehicle.

Free Supercharging is such a great perk because the money an owner saves on charging factors directly into what they are saving if they were to own a gas car. While Supercharging and home charging are, on average, cheaper than filling up with gas, the savings are not massive.

When Supercharging is free, it can save consumers hundreds of dollars per month, especially if they plan to use the Tesla for their daily commute. Some people could fill their gas cars up two times a week to get to work, spending $80-$100 every five days on gas.

Tesla has been using incentives like this to push vehicles into customers’ hands. Q3 could be one of the best three-month spans in recent memory with the push it is making.

Tesla is preparing to take on autonomy’s final boss

India’s city streets are notorious for their complexity and congestion.

If there is any sign that Tesla is now confident about its self-driving program, it would be this. As could be seen on Tesla’s Careers page, the company is now hiring Autopilot Vehicle Operators in Delhi and Mumbai, India. 

As far as real-world traffic is concerned, one could argue that India’s city streets are the final boss of autonomous driving systems due to their complexity and congestion.

Tesla job openings

As per Tesla in its recent job openings, Prototype Vehicle Operators will be responsible for driving an engineering vehicle for extended periods and conducting dynamic audio and camera data collection for testing and training purposes. In both its job listings for Mumbai and Delhi, Tesla noted that successful applicants will be gathering real-world data on the weekends and around the clock. 

Considering the job openings in India, Tesla seems to be intent on rolling out its advanced driver-assist systems like FSD in the country. This is quite interesting, as Tesla is not hiring Prototype Vehicle Operators in other territories that recently launched, such as the Philippines. Perhaps Tesla intends to tackle FSD’s final boss of sorts before rolling out FSD in other territories.

FSD’s rollout

Tesla’s autonomous driving program uses the company’s Full Self-Driving system, which is currently available on vehicles in North America and China. Tesla, however, has a more advanced version of FSD called Unsupervised FSD, which is currently being used in vehicles that are part of the Robotaxi pilot in Austin and the Bay Area.

Elon Musk has also recently announced on X that Tesla will be releasing FSD V14 in the coming weeks. He also shared a number of improvements that can be expected from FSD V14. “The FSD release in about 6 weeks will be a dramatic gain with a 10X higher parameter count and many other improvements. It’s going through training & testing now. Once we confirm real-world safety of FSD 14, which we think will be amazing, the car will nag you much less,” Musk wrote in his post.
