SpaceX Dragon XL could supply NASA astronauts around the Moon and Earth

Published

on

SpaceX’s Moon Dragon could one day deliver supplies to astronauts in Earth orbit on top of its raison d’etre – resupplying NASA’s future lunar space station (Gateway).

Known as Dragon XL, the new SpaceX spacecraft was unexpectedly revealed earlier this year when NASA solely awarded it a Gateway Logistics Services contract potentially worth billions. Dragon XL is almost entirely built out of hardware and systems already built and proven with Cargo Dragon and Crew Dragon over 20 space station launches and two orbital missions, respectively.

Due to NASA’s ever-shifting plans and strategies, however, it’s far from guaranteed that a habitable Gateway will ever actually be built – let alone by the rough 2024 target that’s currently favorable. Given that a huge amount of Dragon XL has already technically been developed, its development should be on the slightly easier side as far as SpaceX programs go. As such, Dragon XL could be ready for flight months or even years before any lunar space station is in place with astronauts to take advantage of it. That possibility raises the question: does NASA plan on SpaceX performing a Dragon XL flight test before its lunar cargo debut?

In the unsurprising event that NASA has arranged for a demonstration mission prior to Dragon XL’s first mission-critical lunar resupply launch, a cargo trip to Earth’s International Space Station (ISS) could be a valuable segue. Effectively an expendable, high-volume amalgamation of SpaceX’s Crew Dragon and Cargo Dragon 2 spacecraft, Dragon XL will lose the ability to return payload to the Earth’s surface (downmass) in return for a dramatic increase in payload upmass.

According to NASA, Dragon XL is designed to deliver up to 7.6 tons (~16,800 lb) of cargo – 5 tons pressurized, 2.6 tons unpressurized – to the lunar Gateway and weigh no more than 14 metric tons upon arrival. Compared to Cargo Dragon 1 and 2, XL thus offers a 25-50% improvement. As an expendable spacecraft, Dragon XL is likely going to be much simpler and lighter than SpaceX’s recoverable and reusable Dragon capsules, it’s also reasonable to assume that the new spacecraft could be substantially cheaper, too. Finally, thanks to that 14 ton Gateway mass target, it’s conceivable that a recoverable Falcon 9 booster could launch a fully-loaded Dragon XL to the ISS without issue, making the cost of launch more or less identical to any other Dragon mission.

On the other hand, though, Dragon XL’s mission is substantially different – and in some ways more challenging – than the Dragons it’s built off of. Notably, the deep space environment can be substantially more challenging from both a thermal management and radiation perspective, while propulsive maneuvers, operations, and autonomous docking so far from Earth would be a first for SpaceX. A demonstration mission to the International Space Station (ISS) would fail to put Dragon XL through any of those unproven scenarios.

Excluding a demo mission to the ISS, a Falcon 9-launched Dragon XL could potentially serve as an extra-cheap option for NASA to deliver large volumes of supplies, hardware, and experiments to the space station, complimenting Cargo Dragon’s reusability and downmass capabilities. Of course, no current contract exists that would allow SpaceX to fly Dragon XL outside of two resupply missions to the lunar Gateway, but NASA is by no means averse to the idea according to Mark Wiese, manager of Gateway Deep Space Logistics.

Ultimately, the likelihood of Dragon XL being coopted for ISS cargo delivery is low but there is clearly a chance that NASA will exploit its substantial investment in the new SpaceX spacecraft for more than just two Gateway supply runs.

Tesla Phone? Not quite, but close: analyst

For years, there have been images and videos across social media platforms that have reminded me of when I was a 15-year-old kid teased by “Xbox 720” videos on YouTube. These videos are of the supposed “Tesla Phone” that Elon Musk was secretly developing in between leading Tesla with its electric cars and SpaceX with its reusable rockets.

Although Musk has put those rumors to bed several times, it was never completely out of the realm that he could get involved in cell phones in some capacity. Think outside the box and more macro-level, though. Instead of reinventing the computer, Musk reinvented connectivity by developing Starlink with SpaceX.

It could be something similar, TD Cowen analyst Gregory Williams said in a note last week, where he hinted SpaceX could be gathering some steam to acquire T-Mobile.

Williams said it would be the “clear choice” for SpaceX if it decided to go through with a network acquisition. He also suggested AT&T.

The move would be possible through selling more of its own stock, which would help SpaceX raise the money to purchase T-Mobile, which would cost roughly $300 billion. It could be one of the moves SpaceX makes post-IPO in terms of an acquisition: it already acquired Cursor AI for $60 billion.

Other analysts, like Dan Ives of Wedbush, believe SpaceX and Tesla will eventually merge into one anyway, and that conglomeration could come as soon as this year, some have said.

The implications of SpaceX purchasing T-Mobile are massive. A combined entity would create a truly ubiquitous network: T-Mobile’s terrestrial 5G towers and Starlink’s growing constellation of Direct-to-Cell satellites. This would essentially eliminate dead zones across the U.S. and potentially globally.

SpaceX would instantly become a full-scale facilities-based carrier with satellite differentiation; a huge advantage. This would pressure AT&T and Verizon heavily.

There are also concerns like a potential reduction in long-term competition, and of course, a deal of that size would face intense scrutiny from government agencies.

The strategic fit is compelling due to the existing Starlink–T-Mobile partnership and complementary technologies (space + terrestrial). It could create a dominant integrated communications player. However, the regulatory, financial, and execution hurdles are enormous — this remains highly speculative with no indication SpaceX is actively pursuing it right now.

Tesla revealed a major new Cybercab detail in a guide it released for First Responders, showing new territory in its beliefs and intentions for the ride-hailing-focused vehicle that entered production in April.

The First Responders Guide is released to give fire departments, paramedics, and other emergency personnel the proper guidance on what to do in the event of an accident, entrapment, or other situation that would require immediate attention.

On one of the pages of the First Responders Guide, Tesla revealed a stark detail about the Cybercab, which could help personnel enter the vehicle more easily in case of an emergency.

Tesla Cybercab has one important piece that AI4 cars might need for FSD

It shows Tesla has no intention of releasing any Cybercab units that were initially proposed for ride-hailing services for the general public with any manual controls, meaning a steering wheel or pedals:

“A Cybercab equipped with steering wheel, brake pedal, and an acceleration pedal is typically an engineering or test vehicle, and operates at SAE Level 2 autonomy. Cybercab is not typically equipped with a steering wheel or acceleration and brake pedals.”

This is a major development for those who continue to believe Tesla planned to release the Cybercab with any sort of manual controls so that passengers could take over if needed. However, when Tesla started manufacturing production versions of the Cybercab in Giga Texas earlier this year, they were spotted without a steering wheel or pedals.

It essentially confirms the company has no intentions of bringing manual controls to the car’s production versions. Some have argued that the likelihood of Tesla having something

There still are some Cybercab units out there with a steering wheel and pedals, and as Tesla said, these cars are engineering or test vehicles, which have Safety Monitors on board to help the car out of a precarious situation or emergency.

Tesla released the Full Self-Driving v14 ‘Lite’ suite to owners of Hardware 3 or AI3 vehicles today, adding several new features to the vehicles that were once believed to be capable of unsupervised self-driving.

Now, Tesla has released this modified suite to older Tesla vehicles, adding plenty of new features and capabilities.

Here are the full release notes for the suite:

  • Distilled the intelligence from HW4 V14 into HW3. This allows HW3 to directly learn how to handle scenarios using HW4 V14 as a guide. This process unlocks the improvements that have been made to HW4 including Reinforcement Learning (RL) and offline models for HW3.
  • Improved both proactive and reactive responsiveness across a wide variety of categories including navigation handling, merges and forks, pedestrian interactions, traffic lights, and vehicle cut-in scenarios.
  • Improved general comfort in nominal scenarios through fewer false slowdowns, smoother steering and more consistent lane centering.
  • Introduced parking, unparking, and reversing capabilities.
  • Added Arrival Options for you to select where FSD should park: in a Parking Lot, on the Street, in a Driveway, or at the Curbside.
  • Speed Profiles are now available at all times, to further customize driving style preference.

These improvements, according to Tesla’s Head of AI, Ashok Elluswamy, help distill the driving behavior from AI4’s v14 series into both the camera and compute configurations of AI3.

Tesla Full Self-Driving v14 ‘Lite’ for older cars finally gets released

He added:

“It includes destination options and speed profiles on city roads, but more importantly significantly improved safety. We hope you’ll enjoy it, once the build ships wide.”

Tesla will continue to roll out the v14 Lite suite more widely in the coming weeks, the company said.
