Relativity Space has shipped both stages of its first 3D-printed Terran-1 rocket to a launch pad it recently finished constructing at Florida’s Cape Canaveral Space Force Station (CCSFS), leaving the startup just a few steps away from its first orbital launch attempt.

As Relativity CEO Tim Ellis himself noted, the company is about two years behind its initial goal of a 2020 launch debut, but it’s far from alone in that regard. Virtually all of its most direct competitors are in similar boats. Out of sheer coincidence, startups ABL Space and Firefly Space are working towards orbital launch attempts of their similarly sized RS1 and Alpha rockets – ABL for the first time and Firefly for the second time – as early as summer 2022. Now, so is Relativity.

Almost simultaneously, all three companies have announced that both stages of their Terran-1, RS1, and Alpha rockets have arrived at their respective launch sites in Florida, Alaska, and California. Firefly, who has already successfully static fired Alpha’s first and second stages, is undoubtedly in the lead, but ABL Space and Relativity are neck and neck for second.

Both of the latter startups have successfully qualified the smaller, less powerful upper stages of their RS1 and Terran-1 rockets. Both intend to conduct final booster qualification testing – including the first all-engine, full-power static fires – at their launch sites. ABL has a bit of a leg up over Relativity, as it delivered its RS1 booster to its Kodiak, Alaska launch pad months ago. Still, Relativity appears to be on a roll and delivered both stages of its unique 3D-printed Terran-1 rocket to its Cape Canaveral launch site just a few weeks apart in May and June 2022. ABL Space also suffered a major failure during its first attempted upper stage qualification, though the company rapidly recovered. At least publicly, Relativity has experienced no major stage failures while developing Terran-1.

Relativity has also qualified its first Terran-1 upper stage and is preparing to static fire the rocket’s booster.

Alpha, RS1, and Terran-1 are all designed to launch roughly 1.2-1.35 tons (2600-3000 lb) to low Earth orbit. All three are roughly the same size and designed to be expended after every launch. Terran-1 and RS1 are designed to launch up to 1.25 and 1.35 tons for $12 million, while Alpha is a bit more expensive at $15 million for 1.17 tons. RS1 is a largely traditional welded-aluminum rocket not unlike SpaceX’s Falcon 1, but with nine smaller booster engines instead of Falcon 1’s one. Alpha is almost entirely built out of carbon fiber composites and is powered by four slightly larger main engines.

Terran-1 has nine 3D-printed booster engines and is also made mostly of aluminum. However, Relativity’s claim to fame is 3D printing, and it says that even its very first Terran-1 rocket is 85% 3D-printed by mass and is the largest single 3D-printed object ever built. Terran-1 reportedly weighs around 9.3 tons (20,500 lb) empty.

If Terran-1’s booster qualification testing goes as smoothly as it did for the rocket’s upper stage, Relativity could be ready for its first orbital launch attempt as early as summer (Q3) 2022, just in time to join Firefly (July) and ABL (August). Relativity Space’s ultimate goal? 3D-print similar rockets on Mars.

Tesla stuns with another FSD approval in Europe, its second in two days

Published

on

Tesla has stunned by gaining yet another approval for its Full Self-Driving suite in Europe, its second in two days and its fifth overall.

Belgium will be the latest country to allow Tesla owners to utilize FSD on public roads in Europe, joining a quickly growing list that started with the Netherlands, Lithuania, and Estonia.

On Tuesday, Denmark announced its approval of the FSD suite, which has now been followed by Belgium just one day later.

The country’s Minister of Mobility, Annick De Ridder, announced the approval on her X account, stating that she had just signed the approval of Tesla FSD. It now goes to the country’s homologation department for the last step of the approval process.

The Belgian approval is one of mighty importance because it truly shows how quickly countries in Europe could greenlight the FSD suite consecutively. Approvals are already coming in relatively quickly, which is a great sign.

Perhaps the next big development that could come from FSD approvals in Europe is an approval from a country like England, Italy, France, Spain, or Germany. It would be something to see how FSD would perform in a major European metro, such as London, Barcelona, Madrid, Paris, Rome, or Berlin.

Full Self-Driving does an excellent job of roaming around major U.S. cities like New York and Los Angeles, but other high-profile international cities of significance would truly mark a line in the sand for Tesla, which can simply enable any vehicle in its customer-owned fleet to run FSD with the correct approvals.

SpaceX’s Elon Musk relieves worries about orbital data centers

SpaceX CEO Elon Musk recently confronted worries about orbital data centers and launching satellites in mass quantities in space, as some voiced concerns about crowding.

Musk’s SpaceX plans to combat the issue of needing data centers by launching them into space instead of taking up valuable real estate on Earth. It has been a major point of SpaceX’s future, including its looming IPO, which could be the largest ever.

In a recent interview filmed at SpaceX’s Starlink terminal factory in Bastrop, Texas, Elon Musk directly addressed concerns that deploying large numbers of AI satellites for orbital data centers could crowd Earth’s orbit. His message was straightforward and reassuring: space is vast beyond human intuition.

“Space is really big,” Musk said. “It’s not like space is gonna get crowded. Space is enormous. If you actually look at it relative to the Earth, the satellites are so tiny you can’t even see them.” He emphasized that even zooming in makes a satellite appear large, but from a planetary perspective, they are minuscule specks.

Musk pointed to SpaceX’s real-world experience operating roughly 10,000 Starlink satellites as evidence that large constellations can be managed safely. “We’ve got a pretty good idea of how to operate just really large constellations and do it safely,” he noted. SpaceX remains the only operator with meaningful experience at this scale, giving the company unique insight into tight orbital packing without compromising safety

The discussion highlighted SpaceX’s plans for “AI1” satellites—essentially orbiting racks of AI compute powered by massive solar arrays and cooled via radiative panels in space’s vacuum.

These satellites leverage proven Starlink V3 technology, making them simpler to design than communications satellites. A first-generation unit targets around 150 kW peak power, with a 70-meter wingspan for solar panels and radiators. Laser links will connect them to each other and the Starlink network, delivering low-latency access (on the order of a few milliseconds from low-Earth orbit).

Musk framed orbital data centers as a practical solution to Earth’s constraints on AI growth. Ground-based facilities face power shortages, water demands for cooling, and grid limitations. In space, constant sunlight (no day-night cycle), vacuum radiative cooling, and abundant solar energy offer clear advantages.

Production will ramp up at an expanded “Gigasat” factory in Bastrop, with solar manufacturing already underway and full AI satellite output expected at reasonable volume by the end of 2027. Starship’s rapid, high-volume launch capability, aiming for multiple flights per hour, will make massive deployment feasible.

Critics sometimes raise risks like space debris or Kessler syndrome, but Musk’s response underscores scale: even a million satellites would represent an imperceptible fraction of available orbital volume when viewed against Earth’s size. SpaceX’s automated collision avoidance and deorbiting designs for Starlink further mitigate concerns.

This vision ties into broader ambitions. Musk sees orbital AI compute as a step toward harnessing more of the Sun’s energy, advancing humanity on the Kardashev scale from a Type 0 civilization toward Type 1 and eventually Type 2. By moving power-hungry data centers off-planet, SpaceX aims to unlock orders-of-magnitude more compute while preserving Earth’s resources.

Musk’s comments should ease public anxiety. With proven operational expertise, incremental engineering, and the immensity of space itself, orbital data centers represent not overcrowding, but smart expansion into the final frontier.

Tesla Full Self-Driving hits Level 4? One analyst says yes

Published

Tesla Full Self-Driving (Supervised) is currently listed as a Level 2 suite in terms of its passenger cars. As its Robotaxi platform continues to move quickly, it has been recognized as a Level 4 ride-sharing program by the State of Texas, as Tesla recently self-certified itself.

However, a Wall Street analyst is arguing that Tesla (NASDAQ: TSLA) has effectively achieved Level 4 autonomy in most conditions in all of its vehicles, drawing on personal experience and data released by the company.

Alex Potter of Piper Sandler said in a note to investors on Wednesday that “Tesla has solved the self-driving puzzle,” pointing to decisions to offer insurance discounts for FSD-enabled policies as a signal of confidence, which is backed up by stellar safety records compared to human driving.

Investing.com initially reported on Potter’s new note.

Additionally, Potter looks at the recent start of Cybercab production at Giga Texas as a potential indication that Tesla is ready to offer some level of unsupervised driving at least in the near future. The Cybercab has no steering wheel or pedals, completely eliminating the ability for human input.

He also sees Tesla’s allocation of “several hundred million USD (if not $1B+)” as confidence internally, seeing as it would be tough to set aside that amount of capital toward a project that the company does not see as relatively near-term.

Forward thinking, especially as Cybercab has no human controls, it would make sense that Tesla is at least close to self-driving. How close is another question.

Tesla has routinely teased that unsupervised FSD is close, but there are still a lot of things it feels as if the company has to roll out some more capability, including unsupervised parking features, known as “Banish,” better operation with regional self-driving performance, and other improvements.

That is not to say that Tesla FSD is super impressive already. It has already completed coast-to-coast drives across the United States and Canada, it routinely takes the stress out of driving for most people, and it has proven through Tesla Safety Reports that it is safer and involved in accidents less frequently than humans.

Even Potter believes it is capable, as he used it to go from Missoula, Montana, to Minneapolis, Minnesota, back in April.

“There’s no substitute for personal experience,” he wrote.
