SpaceX’s Elon Musk: odds of Starship reaching orbit by 2020 are “rising rapidly”

SpaceX CEO Elon Musk has suggested that the company’s newly revamped Starship and Super Heavy rocket (previously known as BFR) could perform its first integrated launches – placing Starship into orbit – as few as 12-24 months from today.

Musk indicated that the odds of Starship reaching orbit as early as 2020 are now as high as “60% [and] rising rapidly”, thanks in no small part to the flurry of radical changes the spacecraft and booster have both undergone over the course of 2018.

Combined with a decision – made public at a September 2018 media event – to delay the debut of a vacuum-optimized upper stage Raptor (RVac) and stick with its mature sea level variant, Musk apparently is quite confident that these dramatic shifts in strategy will allow SpaceX to aggressively slash the development schedules of its next-gen launch vehicle. Intriguingly, Musk noted that while these “radical” design changes were almost entirely motivated by his desire to expedite the fully-reusable rocket’s operational debut, it apparently became clear that the cheaper, faster, and easier iteration could actually end up being (in Musk’s own words) “dramatically better” than its exotic carbon-composite progenitor.

“Delightfully counter-intuitive”

Let there be little doubt – I am still immensely skeptical of this radical redesign and the implausible logistics of conducting said redesign at the last second while somehow maintaining the test schedule, let alone expediting it by 6-9 months. Despite the fact that Musk does seem to have a compellingly rational answer to every question thus far asked, he was no less convincing in mid-2016 when he stated with contagious conviction that Tesla’s Fremont factory would be an almost 100%-automated “alien dreadnought” as early as 2018. There is, of course, nothing wrong per se with being wrong, although taking 24 months and several hundred million dollars to realize as much can be downright fatal or at least a major health risk for any given company that faces such a challenge, as was the case with Tesla.

Skepticism aside, there are equally many reasons to be optimistic about the future of SpaceX’s Starship/Super Heavy (BFR) program over the next several years. Not only do metal hot structures have a proven track record of success (admittedly in the 1960s and for suborbital conditions, but still), but the century and a half humans have been making and building with steel serves to aggressively reduce risk in BFR’s development, whereas a giant, highly-reusable spaceship and rocket built mainly out of carbon composites is about as exotic, challenging, and alien as one could muster. One step further, Musk appears to be dead-set on the trade that the benefits of moving from composite to stainless steel far, far outweigh the costs.

 

Most notably, Musk’s implication that a steel alloy skin – albeit with regenerative (i.e. liquid) cooling – could genuinely stand in for SpaceX’s ablative PICA-X heat shield technology on Starship was the most unintuitive but logical shift yet. Although steel alloys may literally have densities that are significantly higher than carbon composites, composites simply cannot (at least in the current state of the art) withstand high temperatures like those that Starship would inevitably experience during orbital and interplanetary reentries. As a result, Starship would need an extremely advanced heat shield technology that is minimally ablative, extremely lightweight, robust, and shock-resistant, not to mention an additional layer capable of mounting it to Starship’s composite hull while also insulating the propellant tanks and structure from the extreme heat of reentry.

Steel, on the other hand, is one of the least thermally conductive metals available, while also featuring alloys with melting points that can approach and even surpass 1500 degrees C. With regenerative cooling, it’s entirely possible that a hot steel shield and fusion of propellant tanks and load-bearing structures could ultimately result in a spaceship far more reusable, reliable, and perhaps even performant that a spaceship relying on exotic heat shield materials and linerless carbon composite propellant tanks.

Perhaps BFR Block 2 or 3 will make room for dramatically improved composite formulations and production methods down the road, but advanced steel and other metal alloys appear to be the way forward for SpaceX for the time being. For now, we can sit, watch, and wait as something comes together at the company’s South Texas test and launch facilities.

Tesla adds new feature that will be great for crowded parking situations

This is the most recent iteration of the app and was priming owners for the slowly-released Holiday Update.

Tesla has added a new feature that will be great for crowded parking lots, congested parking garages, or other confusing times when you cannot seem to pinpoint where your car went.

Tesla has added a new Vehicle Locator feature to the Tesla App with App Update v4.51.5.

This is the most recent iteration of the app and was priming owners for the slowly-released Holiday Update.

While there are several new features, which we will reveal later in this article, perhaps one of the coolest is that of the Vehicle Locator, which will now point you in the direction of your car using a directional arrow on the home screen. This is similar to what Apple uses to find devices:

In real time, the arrow gives an accurate depiction of which direction you should walk in to find your car. This seems extremely helpful in large parking lots or unfamiliar shopping centers.

Getting to your car after a sporting event is an event all in itself; this feature will undoubtedly help with it:

Tesla’s previous app versions revealed the address at which you could locate your car, which was great if you parked on the street in a city setting. It was also possible to use the map within the app to locate your car.

However, this new feature gives a more definitive location for your car and helps with the navigation to it, instead of potentially walking randomly.

It also reveals the distance you are from your car, which is a big plus.

Along with this new addition, Tesla added Photobooth features, Dog Mode Live Activity, Custom Wraps and Tints for Colorizer, and Dashcam Clip details.

All in all, this App update was pretty robust.

Tesla CEO Elon Musk shades Waymo: ‘Never really had a chance’

Published

Tesla CEO Elon Musk shaded Waymo in a post on X on Wednesday, stating the company “never really had a chance” and that it “will be obvious in hindsight.”

Tesla and Waymo are the two primary contributors to the self-driving efforts in the United States, with both operating driverless ride-hailing services in the country. Tesla does have a Safety Monitor present in its vehicles in Austin, Texas, and someone in the driver’s seat in its Bay Area operation.

Musk says the Austin operation will be completely void of any Safety Monitors by the end of the year.

With the two companies being the main members of the driverless movement in the U.S., there is certainly a rivalry. The two have sparred back and forth with their geofences, or service areas, in both Austin and the Bay Area.

While that is a metric for comparison now, ultimately, it will not matter in the coming years, as the two companies will likely operate in a similar fashion.

Waymo has geared its business toward larger cities, and Tesla has said that its self-driving efforts will expand to every single one of its vehicles in any location globally. This is where the true difference between the two lies, along with the fact that Tesla uses its own vehicles, while Waymo has several models in its lineup from different manufacturers.

The two also have different ideas on how to solve self-driving, as Tesla uses a vision-only approach. Waymo relies on several things, including LiDAR, which Musk once called “a fool’s errand.”

This is where Tesla sets itself apart from the competition, and Musk highlighted the company’s position against Waymo.

Jeff Dean, the Chief Scientist for Google DeepMind, said on X:

“I don’t think Tesla has anywhere near the volume of rider-only autonomous miles that Waymo has (96M for Waymo, as of today). The safety data is quite compelling for Waymo, as well.”

Musk replied:

“Waymo never really had a chance against Tesla. This will be obvious in hindsight.”

Tesla stands to have a much larger fleet of vehicles in the coming years if it chooses to activate Robotaxi services with all passenger vehicles. A simple Over-the-Air update will activate this capability, while Waymo would likely be confined to the vehicles it commissions as Robotaxis.

Tesla supplier Samsung is preparing to manufacture the AI5 chip, which will launch the company’s self-driving efforts even further, with its latest move.

According to a new report from Sedaily, Samsung is accelerating its preparation for U.S. production of the AI5 chips by hiring veteran engineers for its Customer Engineering team, which will help resolve complex foundry challenges, stabilize production and yields, and ensure manufacturing goes smoothly for the new project.

The hiring push signals that Tesla’s AI5 project is moving forward quickly at Samsung, which was one of two suppliers to win a contract order from the world’s leading EV maker.

TSMC is the other. TSMC is using its 3nm process, reportedly, while Samsung will do a 2nm as a litmus test for the process.

The different versions are due to the fact that “they translate designs to physical form differently,” CEO Elon Musk said recently. The goal is for the two to operate identically, obviously, which is a challenge.

Some might remember Apple’s A9 “Chipgate” saga, which found that the chips differed in performance because of different manufacturers.

The AI5 chip is Tesla’s next-generation hardware chip for its self-driving program, but it will also contribute to the Optimus program and other AI-driven features in both vehicles and other projects. Currently, Tesla utilizes AI4, formerly known as HW4 or Hardware 4, in its vehicles.

AI5 is specialized for use by Tesla as it will work in conjunction with the company’s Neural Networks, focusing on real-time inference to make safe and logical decisions during operation.

Musk said it was an “amazing design” and an “immense jump” from Tesla’s current AI4 chip. It will be roughly 40 times faster, and have 8 times the raw compute, with 9 times the memory capacity. It is also expected to be three times as efficient per watt as AI4.

AI5 will make its way into “maybe a small number of units” next year, Musk confirmed. However, it will not make its way to high-volume production until 2027. AI5 is not the last step, either, as Musk has already confirmed AI6 would likely enter production in mid-2028.
