Rocket Lab spacecraft sends NASA’s CAPSTONE mission to the Moon

Published

on

Rocket Lab has successfully sent a small NASA spacecraft on its way to the Moon, acing the complex interplanetary launch on its first try.

The public aerospace company’s (mostly) standard two-stage Electron rocket lifted from its New Zealand-based LC-1 pad on June 28th and inserted NASA’s tiny 25-kilogram (~55 lb) “Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment” (CAPSTONE) spacecraft into a low Earth parking orbit without issue. As is fairly typical for most modern Electron launches, a small ‘kick stage’ was included for orbital operations and payload deployment, but CAPSTONE’s kick stage and destination were anything but typical.

Instead of slightly and briefly tweaking a run-of-the-mill low Earth orbit, CAPSTONE’s kick stage was tasked with sending the spacecraft (and itself) all the way from LEO (~300 kilometers) to a lunar transfer orbit with an apoapsis 1.2 million kilometers (~750,000 mi) from Earth.

To accomplish that feat, Electron’s extensively upgraded Lunar Photon kick stage would need to perform more than half a dozen major burns spread out over almost a week, and survive hostile conditions while maintaining total control throughout. Generally speaking, Rocket Lab offers three kick stage variants: a standard low-thrust, low-longevity stage for small orbital adjustments shortly after launch; an upgraded Photon that can either serve as a long-lived satellite or kick stage; and an even more upgraded Photon with large propellant tanks and a more powerful ‘HyperCurie’ engine. With an impressive 3200+ meters per second of delta V, the latter variant could boost significant payloads into higher Earth orbits but is primarily designed for deep space missions – sending payloads beyond Earth orbit.

Rocket Lab wants to launch its own self-funded mission(s) to Venus, delivering one or several small atmospheric probes to help peel back the curtain on the chronically under-explored planet. It also won a 2021 contract to supply a pair of Mars-bound Photon spacecraft buses for NASA’s Escape and Plasma Acceleration and Dynamics Explorers (ESCAPADE) in 2024, and has multiple orders for simpler Photons that will support slightly more ordinary missions back in Earth orbit.

Lunar Photon’s performance on CAPSTONE bodes extremely well for those ambitious future plans. Within hours of reaching orbit, Photon had begun the orbit-raising process. Over the course of five days, Photon performed six major burns, effectively taking larger and larger ‘steps’ towards the Moon. The spacecraft’s seventh and final burn boosted its apoapsis almost tenfold from ~70,000 to 1.2 million kilometers from Earth, officially placing CAPSTONE on a ballistic lunar trajectory (BLT). While highly efficient, CAPSTONE’s trajectory means it will have to wait until November 2022 to truly enter orbit around the Moon using its own small thrusters.

Once there, “CAPSTONE will help reduce risk for future spacecraft by validating innovative navigation technologies and verifying the dynamics of” lunar near-rectilinear halo orbits (NRHO). The story behind that strange lunar orbit – which will make exploring the Moon’s surface significantly less convenient – is far less glamorous, however. CAPSTONE is essentially a tiny precursor to NASA’s Artemis Program, which the agency claims will help “establish the first long-term presence on the Moon.”

In reality, NASA’s concrete plans currently include a series of short and temporary human landings in the 2020s. While the agency has contracted with SpaceX to develop a potentially revolutionary Starship Moon lander for a single uncrewed and crewed demonstration mission, NASA’s current plan involves using its own Space Launch System (SLS) rocket and Orion spacecraft as a sort of $4 billion lunar taxi to carry astronauts from Earth’s surface to a Starship lander waiting in lunar orbit. Starship will then carry those astronauts to the surface, spend about a week on the ground, launch them back into lunar orbit, and rendezvous with Orion, which will finally return them to Earth.

Orion’s service module delivers about half as much delta V as NASA’s 50-year-old Apollo Service Module, severely limiting its deep space utility and making safe crewed trips to and from low lunar orbits virtually impossible on its own. Instead of improving the spacecraft’s performance and flexibility by upgrading or replacing the European-built service module (ESM) over the last decade, NASA accepted that Orion would only ever be able to send astronauts to lunar orbits that would always be inconvenient for surface operations.

CAPSTONE’s ultimate purpose, then, is to make sure that spacecraft operate as expected in that compromise orbit – only necessary because Orion can’t reach the lower lunar orbits that are already thoroughly understood.

Tesla’s northernmost Supercharger in North America opens

Published

Tesla has opened its northernmost Supercharger in Fairbanks, Alaska, with eight V4 stalls located in one of the most frigid cities in the U.S.

Located just 196 miles from the Arctic Circle, Fairbanks’s average temperature for the week was around -12 degrees Fahrenheit. However, there are plenty of Tesla owners in Alaska who have been waiting for more charging options out in public.

There are only 36 total Supercharger stalls in Alaska, despite being the largest state in the U.S.

Eight Superchargers were added to Fairbanks, which will eventually be a 48-stall station. Tesla announced its activation today:

The base price per kWh is $0.43 at the Fairbanks Supercharger. Thanks to its V4 capabilities, it can charge at speeds up to 325 kW.

Despite being the northernmost Supercharger in North America, it is not even in the Top 5 northernmost Superchargers globally, because Alaska is south of Norway. The northernmost Supercharger is in Honningsvåg, Norway. All of the Top 5 are in the Scandanavian country.

Tesla’s Supercharger expansion in 2025 has been impressive, and although it experienced some early-quarter slowdowns due to V3-to-V4 hardware transitions, it has been the company’s strongest year for deployments.

Through the three quarters of 2025, the company has added 7,753 stations and 73,817 stalls across the world, a 16 percent increase in stations and an 18 percent increase in stalls compared to last year.

Tesla is on track to add over 12,000 stalls for the full year, achieving an average of one new stall every hour, an impressive statistic.

Recently, the company wrapped up construction at its Supercharger Oasis in Lost Hills, California, a 168-stall Supercharger that Tesla Solar Panels completely power. It is the largest Supercharger in the world.

Tesla hints toward Premium Robotaxi offering with Model S testing

Why Tesla has chosen to use a couple of Model S units must have a reason; the company is calculated in its engineering and data collection efforts, so this is definitely more than “we just felt like giving our drivers a change of scenery.”

Tesla Model S vehicles were spotted performing validation testing with LiDAR rigs in California today, a pretty big switch-up compared to what we are used to seeing on the roads.

Tesla utilizes the Model Y crossover for its Robotaxi fleet. It is adequately sized, the most popular vehicle in its lineup, and is suitable for a wide variety of applications. It provides enough luxury for a single rider, but enough room for several passengers, if needed.

However, the testing has seemingly expanded to one of Tesla’s premium flagship offerings, as the Model S was spotted with the validation equipment that is seen entirely with Model Y vehicles. We have written several articles on Robotaxi testing mules being spotted across the United States, but this is a first:

Why Tesla has chosen to use a couple of Model S units must have a reason; the company is calculated in its engineering and data collection efforts, so this is definitely more than “we just felt like giving our drivers a change of scenery.”

It seems to hint that Tesla could add a premium, more luxury offering to its Robotaxi platform eventually. Think about it: Uber has Uber Black, Lyft has Lyft Black. These vehicles and services are associated with a more premium cost as they combine luxury models with more catered transportation options.

Tesla could be testing the waters here, and it could be thinking of adding the Model S to its fleet of ride-hailing vehicles.

Reluctant to remove the Model S from its production plans completely despite its low volume contributions to the overall mission of transitioning the world to sustainable energy, the flagship sedan has always meant something. CEO Elon Musk referred to it, along with its sibling Model X, as continuing on production lines due to “sentimental reasons.”

However, its purpose might have been expanded to justify keeping it around, and why not? It is a cozy, premium offering, and it would be great for those who want a little more luxury and are willing to pay a few extra dollars.

Of course, none of this is even close to confirmed. However, it is reasonable to speculate that the Model S could be a potential addition to the Robotaxi fleet. It’s capable of all the same things the Model Y is, but with more luxuriousness, and it could be the perfect addition to the futuristic fleet.

Rivian unveils self-driving chip and autonomy plans to compete with Tesla

Rivian, a mainstay in the world of electric vehicle startups, said it plans to roll out an Autonomy+ subscription and one-time purchase program, priced at $49.99 per month and $2,500 up front, respectively, for access to its self-driving suite.

Rivian unveiled its self-driving chip and autonomy plans to compete with Tesla and others at its AI and Autonomy Day on Thursday in Palo Alto, California.

Rivian, a mainstay in the world of electric vehicle startups, said it plans to roll out an Autonomy+ subscription and one-time purchase program, priced at $49.99 per month and $2,500 up front, respectively, for access to its self-driving suite.

CEO RJ Scaringe said it will learn and become more confident and robust as more miles are driven and it gathers more data. This is what Tesla uses through a neural network, as it uses deep learning to improve with every mile traveled.

He said:

“I couldn’t be more excited for the work our teams are driving in autonomy and AI. Our updated hardware platform, which includes our in-house 1600 sparse TOPS inference chip, will enable us to achieve dramatic progress in self-driving to ultimately deliver on our goal of delivering L4. This represents an inflection point for the ownership experience – ultimately being able to give customers their time back when in the car.”

At first, Rivian plans to offer the service to personally-owned vehicles, and not operate as a ride-hailing service. However, ride-sharing is in the plans for the future, he said:

“While our initial focus will be on personally owned vehicles, which today represent a vast majority of the miles to the United States, this also enables us to pursue opportunities in the rideshare space.”

The Hardware

Rivian is not using a vision-only approach as Tesla does, and instead will rely on 11 cameras, five radar sensors, and a single LiDAR that will face forward.

It is also developing a chip in-house, which will be manufactured by TSMC, a supplier of Tesla’s as well. The chip will be known as RAP1 and will be about 50 times as powerful as the chip that is currently in Rivian vehicles. It will also do more than 800 trillion calculations every second.

RAP1 powers the Autonomy Compute Module 3, known as ACM3, which is Rivian’s third-generation autonomy computer.

ACM3 specs include:

  • 1600 sparse INT8 TOPS (Trillion Operations Per Second).
  • The processing power of 5 billion pixels per second.
  • RAP1 features RivLink, a low-latency interconnect technology allowing chips to be connected to multiply processing power, making it inherently extensible.
  • RAP1 is enabled by an in-house developed AI compiler and platform software

As far as LiDAR, Rivian plans to use it in forthcoming R2 cars to enable SAE Level 4 automated driving, which would allow people to sit in the back and, according to the agency’s ratings, “will not require you to take over driving.”

More Details

Rivian said it will also roll out advancements to the second-generation R1 vehicles in the near term with the addition of UHF, or Universal Hands-Free, which will be available on over 3.5 million miles of roadway in the U.S. and Canada.

Rivian will now join the competitive ranks with Tesla, Waymo, Zoox, and others, who are all in the race for autonomy.
