SpaceX Dragon XL could double as a crew cabin for lunar space station

Published

on

A recent modification to SpaceX’s Dragon XL lunar cargo resupply contract with NASA suggests that the spacecraft could be used as an extra crew cabin and bathroom at a lunar space station known as Gateway.

The contract modification was made around April 1st of this year and provided SpaceX around $121,000 to complete the latest study on the potential utility of its expendable Dragon XL spacecraft beyond the primary goal of resupplying a space station orbiting the Moon. Designed to deliver at least five metric tons (~11,000 lb) of pressurized and unpressurized cargo to Gateway, Dragon XL will launch on SpaceX’s own Falcon Heavy rocket – currently the only super heavy-lift launch vehicle in operation – and meant to heavily borrow from hardware and systems already developed for Crew and Cargo Dragon.

NASA first announced its selection of SpaceX for the Gateway Logistics Services (GLS) contract back in March 2020. More than a year later, very little has been said (or visibly done) to progress from that announcement to a true contract – an unusually long period of inactivity for such a significant program.

Of note, as recently as April 2021, NASA officials made it clear that they were still in the cryptic process of “reviewing” the Artemis program, leading to such a long delay between the GLS award announcement and finalization of an actual contract with SpaceX. Of note, back when it was announced, NASA’s nominal plan was to begin Dragon XL cargo deliveries as early as 2024 to support the Artemis Program’s first crewed Moon landing attempt.

Since then, however, other crucial aspects – namely the concept of operations and Human Lander System (HLS) meant to carry astronauts to and from the Moon – have evolved significantly. Weeks after NASA’s GLS announcement, the space agency awarded approximately $1 billion to three prospective HLS providers – SpaceX, Dynetics, and a team led by Blue Origin. A little over a year later, NASA announced a shocking decision to award that initial HLS Moon landing demonstration contract to SpaceX and SpaceX alone.

More or less simultaneously, NASA it made it clear that it was seriously studying the possibility of performing Artemis-3 – the first crewed Moon landing attempt in half a century – without Gateway. Along those lines, the SLS-launched Orion spacecraft and HLS lander (a custom variant of SpaceX’s Starship) would dock directly in lunar orbit instead of separately docking to Gateway to transfer crew. NASA’s decision to solely select Starship as its future Moon lander was so surprising in large part because of how starkly the vehicle’s potential capabilities contrast with the rest of the Artemis Program.

As many have already noted, the very existence of a Starship with capabilities close to what SpaceX is working towards – now a practical inevitability for the company to complete its HLS contract – brings into question the architecture NASA has proposed for Artemis. Currently, the nominal plan is to launch astronauts into an exotic high lunar orbit with NASA’s own SLS rocket and Orion spacecraft – an inconvenient orbit only needed to make up for said spacecraft’s shortcomings. Prior to recent developments, Orion would then dock with Gateway. The HLS vehicle would follow and crew would eventually transfer to the lander, which would then carry 2+ astronauts to and from the surface of the Moon and re-dock with Gateway, followed by Orion returning those astronauts to Earth.

Given that Starship offers enough pressurized volume to rival even the vast International Space Station (ISS) in a single launch, the entire concept of Gateway – an almost inhumanely tiny space station – becomes dubious. If Orion also doesn’t need Gateway to transfer its astronauts to the lander, which NASA has all but confirmed, it’s difficult to see what value Gateway could offer outside of a very expensive technology demonstration. Including a planned Falcon Heavy launch of the first two Gateway segments, station production, and the possible need for expensive Dragon XL cargo deliveries, Gateway could easily end up costing NASA $4-5 billion before it hosts a single astronaut.

NASA is already deeply concerned about the apparent likelihood of Congress systematically underfunding the HLS and Artemis programs outside of SLS and Orion, going as far as selecting just a single HLS provider after clearly indicating a desire for redundancy given enough funding. NASA’s HLS contract with SpaceX is expected to cost around $2.9 billion. The next cheapest option – Blue Origin’s proposal – would reportedly cost around $6 billion. In other words, if NASA were able to stop work and Gateway and redirect that funding elsewhere, it could almost already afford two HLS providers without a larger budget.

Given that NASA has selected SpaceX for HLS and GLS, it’s not impossible to imagine that the space agency is growing increasingly aware that Gateway and Dragon XL look more than a little redundant beside the Starship vehicle NASA itself is now funding SpaceX to realize. For now, though, work on all three programs continue. Most recently, NASA and SpaceX are studying the possibility of adding a toilet and using Dragon XL as an extra crew cabin and bathroom to augment the tiny habitable volume of Gateway’s lone habitat. Only time will tell where the cards ultimately fall.

SpaceX readies Starship Flight 14 for a historic journey into uncharted territory

SpaceX finished Starship’s Flight 14 rehearsal, clearing the way for its first orbital flight Monday.

SpaceX has cleared one of the last hurdles before Starship’s first trip to orbit. The company posted on X Thursday afternoon that its launch rehearsal for Flight 14 was complete, keeping the mission on track for Monday, September 28. The launch window opens at 7:15 a.m. CT at Starbase, Texas, and runs for 75 minutes.

A wet dress rehearsal is essentially launch day without the launch. Crews fill Booster 21 and Ship 41 with thousands of tons of extremely cold propellant, run the countdown nearly to ignition, then drain everything back out. It lets engineers catch leaks or equipment problems before anything leaves the pad. SpaceX still needs a launch license from the FAA before the stack, which stands 407 feet tall, can fly.

Flight 14 matters because of where it is going. All 13 previous Starship flights followed a suborbital path, which works like throwing a ball extremely high and far: the vehicle reaches space, but it is always on a course that brings it back down within about an hour. This time, Ship 41 will perform a short engine firing called an orbital insertion burn roughly 25 minutes after liftoff, giving it enough speed to keep falling around Earth instead of back into it. SpaceX plans about six laps at an altitude near 275 kilometers (171 miles) over nearly 10 hours, as Teslarati detailed when the mission was first announced.


Getting into orbit also means Starship has to prove it can get back out. The ship must relight a single Raptor engine in space to slow down for reentry. SpaceX says it will only attempt the orbital insertion burn after flight controllers confirm the hardware needed for that return burn has enough backup, and its flight plan includes health checks that could shorten the mission to two or five orbits.

Flight 14 is also the first to put working satellites into service. Flight 13 carried 20 Starlink V3 satellites in July, but they came back down with the ship because that mission never reached orbit. This time, 26 V3 satellites are meant to stay up and join the constellation within a few weeks. Together they add about 26 terabits per second of network capacity, which SpaceX says is roughly 10 times what a single Falcon 9 launch of older V2 Mini satellites adds. Three of them carry cameras that will photograph Starship’s heat shield in orbit to check for tile damage before reentry.

The hardware has changed too. Ship 41 flies with extra fasteners on tiles in the most vulnerable areas, fixes for gaps where superheated plasma slipped behind tiles, and curved tiles designed to reduce heating between them. Two tiles recovered from Ship 40 will fly again, the first reuse of any part of a Starship heat shield. Booster 21 carries better engine filtering and new relight software after ice clogged three center engines on the previous booster, leaving only eight of 13 engines to restart for its landing burn.

Ship 41 is targeting a splashdown in the Pacific Ocean west of Chile, a new recovery zone after several Indian Ocean landings, while Booster 21 aims for the Gulf. Neither will be caught by the tower on this flight. Elon Musk said in August that a ship catch was likely “in a few months.”

Google just picked SpaceX for its first step into orbital AI

Google will launch its first Project Suncatcher AI satellite on SpaceX’s Transporter-18 rideshare next week.

Google is about to put its own AI chips into orbit for the first time, and it is paying SpaceX to get them there.

The company said Thursday that the first in-orbit test of Project Suncatcher, its research effort to find out whether space can host large-scale AI computing, will fly next week on SpaceX’s Transporter-18 rideshare mission.

The satellite, called MVP, is about the size of a refrigerator and carries four of Google’s Tensor Processing Units, the same chips Google runs in its ground data centers. Google originally planned to launch two custom satellites in 2027, but chose to move faster by integrating its chips into a satellite.

MVP’s solar panels supply about one kilowatt of power, and Google will run Gemini models on the TPUs only in bursts of roughly 15 minutes before the chips shut down so the radiators can shed heat. In a blog post, Google said its Trillium TPUs survived vibration testing that mimicked sustained launch loads of up to 10g, with individual components seeing 50 to 100g, and handled a radiation dose greater than a five year mission would deliver.

SpaceX and Google mull massive partnership on Musk’s orbital data dream: report

Next week’s flight, slated for October 1, follows a relationship that became public in May, when Teslarati reported that Google was in talks with SpaceX for a launch deal tied to orbital data centers. Google also holds a stake of roughly 6% in SpaceX.

The two companies are chasing the same idea from very different starting points. SpaceX’s own orbital compute program is built around the AI1 satellite, a roughly 70 meter structure derived from Starlink V3 hardware that is designed for 150 kW of peak compute, about 150 times the power MVP will draw. Elon Musk has brushed off concerns about crowding orbit with those satellites, and SpaceX is building its Gigasat factory in Bastrop, Texas, to produce them, targeting an annualized rate of about 1 GW of space compute by the end of 2027.

Musk also posted on X on Thursday that “the amount of compute in space will obviously round up to 100% of all compute.”

Google has been more cautious in public. Its research estimates that launch prices need to fall below about $200 per kilogram before an orbital data center can compete with a ground facility on energy cost, a threshold the company believes could be reached around the mid 2030s. The Suncatcher team has said it expects the effort to remain a project rather than a product for years, which leaves the first real test of its hardware riding on a rocket from the company with the most aggressive timeline in the field.

Tesla Cybercab gets initial tie-in to localized, in-house cathode plant

Published

Tesla has taken another concrete step toward owning its battery supply chain, and it’s doing so with what is perhaps the most important vehicle in its short-but-storied history.

On September 23, Tesla announced that it has officially built the first Cybercab with cathode material produced in-house at the company’s first cathode plant in the U.S., and the first in the U.S. overall.

Active cathode material is the most expensive piece of a lithium-ion battery cell, and it often accounts for more than a third of cell cost. For years, the industry sourced a majority of it from Asia, but Tesla’s decision to make it in the United States bodes well for the Cybercab project. This is the latest chapter in Tesla’s vertical integration strategy, which began in public at Battery Day in 2020.

At the Battery Day Event, Elon Musk said the company would build a North American cathode plant and overhaul the process to cut costs and waste, while also making some of the most powerful and long-lasting cells in the industry.

The Austin facility took years to appear. Tesla filed permits for “Project Cathode” in 2022 on land near Giga Texas. By mid-2022, the building frame was up and Tesla later invested hundreds of millions of dollars as part of a larger expansion of the Giga Texas plant. The company stated it was operating the first large-scale cathode production facility in North America to supplement 4680 cell production.

One month later, that material reached a finished Cybercab.

The timing of this breakthrough is monumental for the Cybercab program. As Tesla officially launched the first Cybercab rides to the public earlier this month, production of the ride-hailing-geared vehicle is moving forward on the planned S-curve that CEO Elon Musk told everyone to expect.

Nevertheless, packs of Cybercab units have been spotted throughout the United States, in an effort to potentially activate the fleet as soon as the company gains regulatory approval in various geographic areas.

On top of that, Tesla owning the cathode step and pairing it with its own in-house lithium from the Gulf Coast refinery shortens the supply chain that once stretched thousands of miles and subjects every pack to fewer external price shocks and geopolitical risks.

Tesla is not yet independent of all of its foreign suppliers, as some precursor metals come from mines and chemical plants. But the first in-house cathode Cybercab shows the company is closing the most expensive and most concentrated gap in its battery production efforts. For a vehicle like Cybercab to operate at a high utilization within the Robotaxi network, that control over cost is so crucial.

It is arguably as important as the software that drives it.
