NASA’s first Artemis Moon mission a flawless success after Orion splashdown

Published

on

NASA has successfully recovered an uncrewed version of its Orion crew capsule, marking the flawless completion of the spacecraft’s first Moon mission and the Space Launch System (SLS) rocket’s first launch.

Six years behind schedule, roughly $20 billion over budget, and costing taxpayers almost $50 billion through its first full flight test, anything less than near-perfection would have been a moderate scandal. But to the credit of NASA and its contractors, who have all worn excuses in the spirit of ‘perfection takes time’ threadbare, the international team behind Artemis I appears to have actually delivered on those implied promises. While some small bugs were unsurprisingly discovered over the 25-day mission, a collection of excellent post-launch NASASpaceflight.com interviews confirm that each major part of the SLS rocket performed about as flawlessly as their respective teams could have hoped for.

Originally intended to launch in late 2016, the first SLS rocket lifted off with the second space-bound Orion spacecraft on November 16th, 2022. Propelled by its European Service Module (ESM), Orion passed the Moon around November 21st. It then entered an unusual distant retrograde orbit (DRO) around the Moon on November 26th, reaching a record distance of 432,200 kilometers (268,563 mi) from Earth in the process. After less than a week in lunar orbit, Orion departed DRO on December 1st and began a long journey back to Earth.

On December 11th, about four weeks after liftoff, Orion separated from its disposable service module (~$400 million) and slammed into Earth’s atmosphere traveling around 11 kilometers per second (~25,000 mph). In another credit to NASA and capsule contractor Lockheed Martin, Orion’s reentry, descent, and splashdown all went perfectly. After its ablative heat shield did most of the work slowing it down, the spacecraft deployed parachutes and splashed down in the Pacific Ocean some 240 kilometers (~150 mi) off the coast of Mexico’s Baja Peninsula, southwest of California.

Taking full advantage of the fact that Orion and SLS are a government program and continuing in the footsteps of the Apollo Program, the US Navy was tasked with Orion spacecraft recovery. To that end, it deployed USS Portland – a 208-meter-long amphibious transport ship crewed by hundreds of sailors – to recover Artemis I’s Orion, which was completed without issue using the ship’s Navy helicopters, fast boats, and floodable well-deck.

Following capsule recovery, which wrapped up almost seven hours after splashdown, it’s safe to say that NASA’s Artemis I mission was a spectacular, near-perfect success. Only a few aspects detract from the extraordinary performance of the spacecraft. Most significantly, despite being half a decade behind schedule and billions of dollars over budget, Artemis I’s Orion capsule and service module did not fly with or test a functioning docking port or Environmental Control and Life Support System (ECLSS). Those systems will not be tested in space until Artemis II, Orion’s first astronaut launch, inherently reducing the risk-reduction and predictive value of the flight test.

Additionally, Artemis I launched Orion to a distant retrograde lunar orbit. No future NASA missions are scheduled to use DRO. For the time being, Artemis II will be a free-return lunar flyby mission, meaning that Orion will never enter orbit around the Moon – the safest possible lunar trajectory for its crewed debut. For Artemis III and all future Orion missions, the spacecraft will enter a different near-rectilinear halo orbit (NRHO) around the Moon – similar to DRO in spirit but entirely different in practice. That again slightly reduces the value of Orion’s spectacular performance during Artemis I.

Waiting for Artemis II

Finally, due to a series of decisions and the shockingly slow expected performance NASA and its contractors, the next Orion and SLS launch is unlikely to occur before 2025. Recently discussed by the US Government Accountability Office (GAO) in a September 2022 report [PDF], the cause is strange. GAO says that “NASA estimates it will require ~27 months between Artemis I and Artemis II due to Orion integration activities and reuse of avionics from the Artemis I crew capsule on…Artemis II.” In other words, even though Artemis I was near-flawless, Artemis II will be delayed partly because of an attempt to reuse a tiny portion of its successfully recovered capsule.

All four proposed SLS variants.

Ars Technica’s Eric Berger recently provided another tidbit of painful context with the discovery that the decision to reuse the first deep space Orion’s avionics boxes was made eight years ago to close a “$100 million budget hole.” Inexplicably, NASA and Lockheed Martin believe it will take more than “two years to re-certify the flight hardware.” Berger explains that years ago, NASA only intended to launch SLS’s first Block 1 variant once, and expected that it would take at least three years to retrofit the rocket’s sole launch tower for the rocket’s Block 1B upgrade and second launch overall.

Years later, parochial pork-hungry members of Congress leaped on an opportunity to force NASA to build a second launch tower to help avoid that three-year gap between launches. Ironically, that second tower, ML-2, is now expected to cost anywhere from 2.5 to 4 times more than its original $383 million price tag and is years behind schedule. Meanwhile, SLS Block 1B is also years behind schedule, which led NASA to decide to launch SLS Block 1 three times instead of just once.

Ultimately, that means that the bizarrely slow recertification of eight Artemis I Orion avionics boxes – not the SLS rocket, ground systems, or any rework required after their launch debut – is now “the primary critical path for…Artemis II.” As a result, Berger estimates that delays caused by the decisions NASA made to save $100 million almost a decade ago will likely end up costing taxpayers $1 billion.

Artemis II is unlikely to launch less than 27 months after Artemis I, pegging the launch no earlier than February 2025. That gap of more than two years is just 20% shorter than the 33-month gap a NASA advisor once said could raise safety concerns because of the loss of experience that would result, which factored into the decision to build a second launch tower. Ultimately, NASA appears to have secured another very large chunk of time to ensure that Artemis II – like Artemis I – goes as perfectly as possible when the time finally comes.

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.
