LNG: TESLARATI

SpaceX appears to have selected Falcon 9 B1056 to become the first booster to have all four landing legs retracted and stowed. While relatively minor in the scope full Falcon 9 booster reuse, in-situ leg retraction could save SpaceX days of recovery and preflight work, a big help for truly rapid reusability.

A handful of prior retraction attempts have been made on Block 5 boosters but unknown issues prevented the process from taking hold. With some modifications to the legs and their deployment/retraction mechanisms, SpaceX seems to have solved those issues and is ready to graduate to a new level of rapid and easy rocket reusability. Teslarati photographer Tom Cross was on site in Port Canaveral, Florida when SpaceX began its first operational leg retractions and was able to capture photos and videos of the process.

Falcon 9 doesn’t even lift

The crux of the need for a relatively complex crane-and-jig method of leg retraction rests on SpaceX’s landing leg design. Put simply, after rapidly deploying with a combination of gravity and hydraulics, Falcon 9 landing legs have no built-in way to return to their stowed state. Each of the four legs are quite large, weighing around 600 kg (1300 lb) and stretching about 10m (33 ft) from hinge to tip. They use an intricate telescoping carbon fiber deployment mechanism to give the legs enough strength to stand up to the forces of Falcon 9 booster landings.

Combined, the legs’ size and telescoping mechanism makes the addition of an onboard retraction mechanism impractical. All the needed hardware would struggle to find a good place for installation and would quite literally be dead weight during launches and landings, stealing from Falcon 9/Heavy payload capacity and generally serving no purpose until a booster has been lifted off the ground with a giant crane.

As a result, SpaceX engineers instead decided to separate leg retraction hardware from the rocket itself and designed a custom crane jig. Pictured above, the jig attaches to Falcon 9’s interstage and allows the crane operator to lift the entire booster as needed. It also features four independent motors and pulleys that are meant to attach to a specific port on the outside of each booster landing leg. The jig then lifts the landing legs up, nominally retracting the telescoping deployment mechanism, at which point latches should be able to safely secure the legs to the booster’s body.

This has been significantly more difficult than expected, judging from a number of retraction attempts over the past six or so months. Falcon 9 Block 5 debuted in May 2018 – in fact, almost exactly one year ago – and SpaceX has since built 11 boosters that have supported 15 launches. SpaceX has thus taken ~12 months to get to a point where Falcon 9’s landing legs can be safely retracted, perhaps owing more to the fact that said legs are of minimal monetary value relative to the rest of a recovered booster. Improving leg retractibility is a bit of a luxury in that sense, as retracting legs offers little value proposition in terms of significantly lowering the cost of launch or reuse.

What leg retraction does do, however, is shave a significant amount of time off of the process of booster recovery and post-recovery processing. Instead of the normal process of totally dismantling and removing the legs piece by piece, stowing Falcon 9’s legs saves not only the time it takes to remove them but also the time it then takes to reinstall said legs for the next launch. At a minimum, this could save 12-24 hours of dedicated work, up to as much as several days according to CEO Elon Musk. Taken to the extreme, it’s likely that SpaceX’s ultimate goal is to lift a booster off the drone ship, retract its landing legs mid-air (or close), flip the booster horizontal, and lower it onto a transporter in one fluid movement.

If SpaceX can arrive at something approximating that in the near future, the company will be well on its way accomplish Musk’s goal of launching the same Falcon 9 booster twice in ~24 hours. Even further down the road, if or when SpaceX manages to optimize the reusability of its Falcon 9 boosters to the extent that almost zero refurbishment or in-depth inspection is needed between launches, minimizing the amount of human effort that goes into something as basic as preparing landing legs may actually have a significant impact on launch costs. For the time being, we get to enjoy the new and unusual spectacle of a giant reusable booster carefully stowing its landing legs for another launch attempt.

Tesla is concerned about a global shortage of minerals required for production of electric vehicle batteries, with the electric car maker recently warning major industry players and US government representatives of an upcoming mineral supply challenge due to underinvestment in mining sources, according to a report published by Reuters. Representatives in the US government who are both aware and focused on the shortage issue have introduced legislation in the Senate to address delays rooted in the federal approval process. The bill, titled the “American Mineral Security Act”, was presented at the same closed-door conference where Tesla expressed its concerns last week.

“Our bill takes steps that are long overdue to reverse our damaging foreign dependence and position ourselves to compete in growth industries like electric vehicles and energy storage,” Lisa Murkowski (R-Alaska), the main sponsor of the bill, said in a statement about the legislation. Senators Joe Manchin (D-W. Virginia), Martha McSally (R-Arizona), and Dan Sullivan (R-Alaska) are co-sponsors.

The bill specifically requires that a list of critical minerals be compiled at least every three years along with a resource assessment of those minerals nationwide. This data is then used to target and implement reforms in the federal regulatory process aimed at reducing government-driven delays in the mining approval process.

As a major consumer of minerals required for the production of electric vehicle (EV) batteries and other vehicle parts, Tesla will need stable access to mined resources like copper, nickel, and lithium in the long term. The expansion of the EV market will continue to increase demand for these resources. Other tech players such as Amazon and Alphabet also need the same resources for the production of their digital assistants and home connectivity devices.

Tesla’s global supply manager for battery metals, Sarah Maryssael, spoke with representatives present at the industry conference about Tesla’s concerns regarding the company’s mineral needs. Maryssael noted that a “huge potential” existed for mining partnerships in Australia and the US to help with the supply issue, possibly citing a preliminary deal between the two countries for a joint effort towards research and development in the area.

The global demand for copper, in particular, is expected to increase from the current 38,000 tons per day to 1.5 million tons by 2030, and this estimate has driven major copper production companies to expand its mining activities in the US and Indonesia. Electric cars use twice as much copper as gas-powered cars, making the EV industry particularly sensitive to its market availability.

Tesla’s needs from the mineral industry go well beyond copper. The company’s Nevada-based Gigafactory 1 facility is expected to hit 255 GWh annual production of batteries once complete. At that rate, the current global supply of lithium will need to increase nearly three times over to meet the demand. Unlike copper, though, investments in lithium production are ongoing, and Tesla’s ramping need for the mineral is driving significant expansion in part of the mineral market.

Rivian has been on a promotional whirlwind since the company came out of the shadows last year at the 2018 LA Auto Show, and with it, the all-electric adventure company’s attendance at the New York International Auto Show this year has now generated quite a few more vehicle detail revelations from interviews posted online by show attendees.

Brian Gase, Rivian’s Chief Engineer of Special Projects, appeared in a number of videos describing features of the R1T truck and R1S SUV that are unique and otherwise not commonly known about the vehicles.

First, the number of storage compartments were one of the smaller details that stood out. In the R1T, the back passenger seats have bins underneath the cushions, and both vehicles have sliding bins underneath the driver and shotgun seats. A full size spare tire is in the R1T bed and can be removed for even more storage if needed, but to save space for storage and its usable third row seating, the R1S has an inflatable spare tire under the trunk floor.

Rivian’s plans for interior color options were also mentioned, and there are three: Forest Edge (the green inside the demo R1T), Lunar Rock (the grey inside the demo R1S), and black. Additional premium options will be offered for interior fabrics which are already a blend of traditional materials and the types of fabrics you’d find in durable outerwear. The cabins also feature quad-zone climate control.

On the performance side, 170 kW of independent power is provided to each wheel which also provides for torque vectoring. The approximately 750-800 total horsepower in each vehicle works out to about 180 hp per wheel from each of the four motors.

Rivian’s high density battery pack, complete with a thermal control system that adapts according to charging and driving behavior, then powers the whole package. A giant battery might not seem like it would be a great choice for four-wheel adventures, but Rivian has tightly encased its vehicles’ power supply using advanced materials science to be capable of wading up to three feet of water. Since there’s no engine requiring air, only buoyancy prevents a deeper crawl.

Progress in the automotive self-driving arena is moving fast, and Rivian has already integrated that reality into the R1T and R1S designs. The camera and radar hardware on production vehicles will be capable of Level 3 autonomous driving that’s upgradable via over-the-air software updates. Rivian’s initial vehicles will ship with Level 2 capabilities and use data accumulated from its customers’ driving sent to the cloud to develop its Level 3 transition, very similar to Tesla’s strategy. Previously, Rivian has additionally suggested Jurassic Park-style autonomous tours might be available for owners wanting a guided, real-world adventure experience.

Rivian has several test mules on the road using F-150 bodies, but only one production design model of each car has been made to be used at shows and in videos.

Finally, you might know that Rivian was founded in 2009 by CEO RJ Scaringe, an MIT graduate (he holds an MS and PhD in mechanical engineering), but it seems lesser known how his personal life story is imprinted right in the company’s name. Scaringe grew up near the Indian River region of Florida, and that’s where the Rivian name is derived (RIV(er)-(Ind)IAN).

BACK TO BASICS

All of those tidbits will now join the overall more well known features driving the appeal of Rivian’s R1T truck and R1S SUV. A recap of the basics may put them into a better perspective still.

On battery packs, Rivian’s focus on outdoor adventure means that decent battery capacity and range are key components if their product ideas are to be successful, and their much-touted 180 kWh battery “megapack” boasting a 400+ mile range seems to fit that bill. The mid-range 135 kWh pack claiming a 300 mile range is also decent for well-planned routes, and it just so happens to have a fun number of 2170 battery cells – 7,777 exactly if you count the battery inside the in-door flashlight. The 135 kWh battery pack vehicles are also the versions that will do 0-60 mph in 3 seconds, although all versions are speed limited to 125 mph. A lower end 105 kWh pack with a 230 mile range will be produced last, per the usual new EV strategy of offering premium cars before more affordable variations.

I’m exhausted, feet hurt, & nursing a migraine but… I got to meet Brian Gase, Chief Engineer at @Rivian and got some great pics of the R1T & R1S, incl the door flashlight I love. Lol. Thx!He humored me and gave a demo. 👐Now for some NYC gourmet b4 home for nap! #NYautoshow pic.twitter.com/gs5XfMNPGQ

The first R1S and R1T deliveries are set for the end of 2020, and Rivian is currently taking preorder deposits to reserve their upcoming vehicles. Purchase prices will start at $69,000 for the R1T and $72,500 for the R1S before tax incentives.

Aside from being first to unveil a near-production all-electric pickup truck, two other features in Rivian’s electric cars have stood out. First, the quad-motor “skateboard” chassis that forms the base of current and future vehicles centralizes and simplifies Rivian’s innovations into a flexible electric car platform for its future product lines. This feature has also drawn interest from big-name partners like GM and Ford, the latter having just signed a $500 million deal with Rivian to use its tech to develop their first all-electric vehicle.

A somewhat new tidbit about the skateboard platform is the size difference between the R1S version and the R1T version. The R1S chassis is 375 mm shorter than the R1T to boost its off-road capabilities. Both vehicles’ towing capacity is around 11,000 pounds.

The second well-known feature about Rivian’s two outdoor-purposed vehicles is the amount of storage space incorporated into the designs. The frunks are spacious with a 330 mL capacity, and the R1T truck has what they call a ‘gear tunnel’, which is essentially a large cargo space tunneled through the lower middle of the truck’s cab. It looks to have the makings of the next social media photo craze, but that’s obviously speculation.

Both the frunk and tailgates have powered open and close functions for ease of use, the tailgate opening a full 180 degrees, and the bed has a powered built-in tonneau cover strong enough to support loading. Also included in the truck bed are 110V power outlets, onboard air, lights to illuminate the bed, and a gear cable that’s electronically connected to the vehicle. If the cable is cut or disconnected for any reason, the owner receives a notification on their Rivian app.

Other details to mention are the electrochromatic glass roof built into both the R1T and R1S that can change color on demand, specifically in response to outside weather and light conditions, and the daytime running lights that also act as turn signals and charging status indicator lights. A charging status indicator is also in the back of the vehicles.

The last major Rivian feature to mention is the adaptable air suspension. Both vehicles’ ride height can be easily raised or lowered depending on road conditions to adjust comfort and handling characteristics. There’s even a ‘kneel’ mode to ease vehicle entry and exit.

STILL TO COME

Rivian’s R1T truck and R1S SUV already have enough innovative details to drive their consumer appeal as-is, but the company has even more developments going on in the background. Recently published patent applications have revealed a modular system for swapping out vehicle components based on activity need and a digital jerry can to extend the battery range even further for longer trips away from a charging network.

Additionally, trademark applications filed with the US Patent and Trademark Office have teased several other products in the works with names like 1C, 1A, and 2R. An interview with RJ Scaringe published by Bloomberg confirmed that Rivian is indeed working on six other products.

Details surrounding Rivian’s plans for a service network are still slim despite the abundance of other important information about the Michigan-based company. The R1S and R1T vehicles will use CCS charging ports, but whether a charging partnership or a home-grown effort is planned remains to be seen.

A NY International Auto Show attendee recently posted on Reddit details gathered from speaking with Rivian’s team, including Scaringe, and indications were made that the company is interested in using Tesla’s Superchargers, although they’ve had some difficulties with the effort. A potential roadshow tour offering test drives was also mentioned.

A couple of the Rivian video interviews can be watched below:

SpaceX CEO Elon Musk has published the first official renders of the company’s updated stainless steel Starship, offering glimpses of the spacecraft on both the Moon and Mars.

Although the designs of Starship and Super Heavy (formerly BFS and BFR) have shifted significantly over the past three years, the vehicle’s primary destinations have remained stable. Above all else, SpaceX remains focused on designing its next-gen rocket to be the best spacecraft ever built for transporting huge payloads and humans to the Moon, Mars, and ultimately throughout the solar system. The interplanetary future of Starship is currently an unknown quantity but SpaceX is already building the first full-scale orbital prototype and testing multiple finished versions of the Raptor engine that will power it.

As discussed earlier today, SpaceX has already completed a low-fidelity prototype of Starship known as Starhopper, designed to – per its namesake – perform low-altitude, low-velocity hop tests. Powered by Raptor, Starhopper also acts as a mobile test stand for the next-gen rocket engine meant to power both Starship and its Super Heavy booster. SpaceX’s current planning has delayed a vacuum variant of the engine for several years, instead choosing to standardize the same Raptor engine across both stages of BFR. Starship will feature seven Raptor engines producing ~14,000 kN (~3.2M lbf) of thrust, while Super Heavy’s latest iteration would require a 31 Raptors and produce a staggering 62,000 kN/14M lbf of thrust at liftoff.

That performance – theoretically making Starship/Super Heavy almost two times as powerful as Saturn V – is essential to support massive missions to Mars and the Moon while also enabling complete reusability of the rocket. SpaceX rightly judged that rapid, low-effort reusability is the only way to truly revolutionize the cost of access to orbit, at least for the indefinite future. This need itself piggybacks on CEO Elon Musk’s founding motivation: to make humanity a multi-planetary species and protect it against future mass-extinction events.

Musk has long viewed the Moon as a distraction to that goal, offering very little prospect of being more than a detour, but both NASA and the political apparatus currently controlling the US have decided that a rebranded Moon return is desirable. Repeating several nearly identical Moon return proposals from the last few decades, the political powers that be have yet to actually put any money where their mouths are. SpaceX and Musk have nonetheless jumped on the bandwagon, a pragmatic decision to hedge bets in case funding actually appears. Unsurprisingly, SpaceX is interested in any opportunity to acquire federal funding for its expensive Starship/Super Heavy/Raptor development programs.

In September 2018, SpaceX announced plans to send Japanese billionaire Yusaku Maezawa and 8-10 artists of his choice on the first Starship mission around the Moon. According to Musk, that could happen as early as 2023 but will necessarily be preceded by at least one uncrewed demonstration of Starship’s performance in deep space. Given the nominal reusability of Starship, the same spacecraft might perform both missions.

In the meantime, SpaceX is in the process of building the first orbital Starship prototype, although it’s unclear just how advanced the vehicle will be. Depending on how polished and successful SpaceX’s Starship Alpha (for lack of a better term) is, it’s conceivable that the spacecraft could be retrofitted or upgraded for actual demonstration missions to deep space or the Moon. To enable the long-term reusability of Starships, SpaceX will need to rely on in-orbit refueling by way of dedicated tanker launches. However, a lower-fidelity prototype that might otherwise be scrapped could be a prime candidate for a one-way Moon-impact or lunar-landing mission, reducing risk for future crewed or uncrewed Starship missions to the Moon before SpaceX has the facilities and hardware to support simultaneous Starship and tanker launches.

Tesla rival Volkswagen has taken a stand against a debunked yet insistent argument against all-electric vehicles. In a recent study involving one of its  most popular vehicles, the German automaker declared that EVs have a smaller carbon footprint than their internal combustion-powered counterparts, even if they are not charged from renewable sources.

Volkswagen used two of its vehicles, a Golf TDI and an e-Golf for its study. The e-Golf produced 57g/km of carbon dioxide per vehicle, which is higher than the Golf TDI’s 29g/km of CO2 per vehicle. This is the only time that the electric car’s carbon footprint exceeded that of its diesel counterpart, since when it came to charging and operating the vehicles, the e-Golf proved far cleaner than its diesel-powered sibling.

Driving the Golf TDI resulted in an average CO2 output of 111g/km, which was notably higher than the 62g/km CO2 produced by the e-Golf when charging. Volkswagen estimated that this figure could drop to as low as 2g/km if the electric car were charged using renewable energy. With these calculations in mind, the German carmaker noted that the diesel-powered Golf TDI produced an average of 140g/km over its lifetime. The e-Golf, on the other hand, produced an average of 119g/km over its lifetime.

The Volkswagen-backed study mirrors the findings of a previous analysis by research organization BloombergNEF, which concluded that the CO2 emissions produced by electric vehicles charged from non-renewable power were still 40% lower than cars operating with internal combustion engines. This gap, of course, is set to get smaller with the introduction of more efficient battery technology and more sustainable automotive manufacturing processes.

Credit is due to Volkswagen for taking a stand against a persistent piece of misinformation that has been peddled for years. The study, if any, is yet another sign that one of Germany’s largest of automakers is beginning to take the upcoming electric car revolution seriously.

This is highlighted by Volkswagen’s recent public comments, as shown when the carmaker acknowledged Tesla for establishing that the demand for electric vehicles is there. The company also made headlines when CEO Herbert Diess encouraged BMW and Daimler to commit to an all-electric future. After Das Auto’s agreement, BMW member of the board Klaus Fröhlich confirmed that Germany would be moving away from other alternative forms of propulsion like hydrogen, as the country’s automakers will be focusing on all-electric vehicles instead.

While Volkswagen is arguably one of Tesla’s loudest rivals with its constant releases of concept all-electric vehicles that are yet to enter production, the company has shown some earnest interest in the electric car maker’s work. During the final days of Elon Musk’s short-lived attempt to take Tesla private last year, the CEO received a number of offers from investors willing to fund company’s privatization at $420 per share. The deal, which was estimated to cost around $30 billion, attracted a number of prominent investors, one of which was none other than Volkswagen AG.
