SpaceX to launch quartet of mini geostationary satellites in 2023

Published

on

Startup Astranis has purchased a dedicated Falcon 9 launch from SpaceX for four miniature geostationary communications satellites.

Known as MicroGEO, the comparatively tiny satellites Astranis is building aim to offer prospective customers an alternative to the immense, expensive satellites that dominate modern geostationary (GEO) communications. Where those flagship satellites tend to weigh anywhere from three to seven metric tons (~6,500-15,500 lb) at liftoff, MicroGEO satellites will weigh around 400 kilograms (~900 lb) – at least a magnitude lighter. Astranis also believes it will be able to eke out about 10 gigabits per second (Gbps) of bandwidth from each tiny satellite, giving them a level of performance that could actually be proportionally comparable to or greater than much larger satellites.

While it’s not clear that Astranis is actually selling its MicroGEOs for “1/20th the cost of traditional GEO communications satellites,” as they claim, the startup has found plenty of customers.

As of March 2022, Astranis has secured contracts to build 11 MicroGEO satellites for a range of customers: one for Alaska’s Pacific Dataport, eight for in-flight and at-sea connectivity provider Anuvu, and one or two for Peru’s Grupo Andesat. Astranis says its deal to launch one satellite for Andesat – with an option for a second – is worth more than $90 million. At that price tag, MicroGEO might cost about half as much as a more traditional entry-level GEO satellite but will only offer 10 Gbps for the money. For twice the price, a prospective customer could easily buy a satellite with at least five to ten times the throughput.

In that sense, MicroGEOs are actually more expensive relative to the performance they offer. Their main benefits appear to be a lower cost of entry, significantly lower launch costs, and the ability to dedicate a whole satellite to a relatively small region or niche service. In that sense, MicroGEO’s draw might be comparable to the reason some launch customers prefer a more expensive dedicated launch on a small rocket over a much cheaper launch as one of many rideshare payloads on a large rocket. For that premium, dedicated launch customers don’t have to worry about the logistics of juggling dozens of other satellites, the risk of related launch delays, or the general need to compromise with other passengers.

While MicroGEO satellite might be significantly less cost-efficient than larger alternatives, smaller customers may find paying a premium preferable to having to find or compromise with other customers to avoid wasting any leftover bandwidth. Additionally, in some unique situations, dedicated MicroGEO satellites may actually be several times cheaper for customers. CEO John Gedmark says that for Peru’s Andesat, MicroGEO offers a “factor of three or a factor of four cost decrease…compared to what they’re paying today [to lease less capacity on existing satellites].”

It’s clear that Astranis’ customers see significant value in MicroGEO. On top of Astranis’ current backlog, Gedmark recently revealed that the company is working on deals for “dozens” of additional satellites and believes that “there will be more than 100 Astranis satellites in active service” by 2030. That means that Astranis’ unique Falcon 9 contract is likely to be the first of many. For perhaps as little as $50 million, a SpaceX Falcon 9 rocket will launch four MicroGEO satellites at once. The relatively tiny payload – likely less than two tons (~4400 lb) – will allow Falcon 9 to launch into a more energetic geostationary transfer orbit (GTO), significantly reducing the amount of time the MicroGEOs will need to reach operational orbits.

Tesla Full Self-Driving appears to have a new behavior that is the perfect answer to aggressive drivers.

According to a recent video, it now appears the suite will automatically pull over if there is a tailgater on your bumper, the most ideal solution for when a driver is riding your bumper.

With FSD’s constantly-changing Speed Profiles, it seems as if this solution could help eliminate the need to tinker with driving modes from the person in the driver’s seat. This tends to be one of my biggest complaints from FSD at times.

A video posted on X shows a Tesla on Full Self-Driving pulling over to the shoulder on windy, wet roads after another car seemed to be following it quite aggressively. The car looks to have automatically sensed that the vehicle behind it was in a bit of a hurry, so FSD determined that pulling over and letting it by was the best idea:

We can see from the clip that there was no human intervention to pull over to the side, as the driver’s hands are stationary and never interfere with the turn signal stalk.

This can be used to override some of the decisions FSD makes, and is a great way to get things back on track if the semi-autonomous functionality tries to do something that is either unneeded or not included in the routing on the in-car Nav.

FSD tends to move over for faster traffic on the interstate when there are multiple lanes. On two-lane highways, it will pass slower cars using the left lane. When faster traffic is behind a Tesla on FSD, the vehicle will move back over to the right lane, the correct behavior in a scenario like this.

Perhaps one of my biggest complaints at times with Full Self-Driving, especially from version to version, is how much tinkering Tesla does with Speed Profiles. One minute, they’re suitable for driving on local roads, the next, they’re either too fast or too slow.

When they are too slow, most of us just shift up into a faster setting, but at times, even that’s not enough, see below:

There are times when it feels like it would be suitable for the car to just pull over and let the vehicle that is traveling behind pass. This, at least up until this point, it appears, was something that required human intervention.

Now, it looks like Tesla is trying to get FSD to a point where it just knows that it should probably get out of the way.

Tesla’s Megapack battery systems will be deployed as part of a 400MW AI data center campus in Uberlândia, Brazil. The initiative is described as one of Latin America’s largest AI infrastructure projects.

The project is being led by RT-One, which confirmed that the facility will integrate Tesla Megapack battery energy storage systems (BESS) as part of a broader industrial alliance that includes Hitachi Energy, Siemens, ABB, HIMOINSA, and Schneider Electric. The project is backed by more than R$6 billion (approximately $1.1 billion) in private capital.

According to RT-One, the data center is designed to operate on 100% renewable energy while also reinforcing regional grid stability.

“Brazil generates abundant energy, particularly from renewable sources such as solar and wind. However, high renewable penetration can create grid stability challenges,” RT-One President Fernando Palamone noted in a post on LinkedIn. “Managing this imbalance is one of the country’s growing infrastructure priorities.”

By integrating Tesla’s Megapack systems, the facility will function not only as a major power consumer but also as a grid-supporting asset.

“The facility will be capable of absorbing excess electricity when supply is high and providing stabilization services when the grid requires additional support. This approach enhances resilience, improves reliability, and contributes to a more efficient use of renewable generation,” Palamone added.

The model mirrors approaches used in energy-intensive regions such as California and Texas, where large battery systems help manage fluctuations tied to renewable energy generation.

The RT-One President recently visited Tesla’s Megafactory in Lathrop, California, where Megapacks are produced, as part of establishing the partnership. He thanked the Tesla team, including Marcel Dall Pai, Nicholas Reale, and Sean Jones, for supporting the collaboration in his LinkedIn post.

Starlink is now powering Europe’s first commercial satellite-to-smartphone service, as Virgin Media O2 launches a space-based mobile data offering across the UK.

The new O2 Satellite service uses Starlink’s low-Earth orbit network to connect regular smartphones in areas without terrestrial coverage, expanding O2’s reach from 89% to 95% of Britain’s landmass.

Under the rollout, compatible Samsung devices automatically connect to Starlink satellites when users move beyond traditional mobile coverage, according to Reuters.

The service initially supports text messaging along with apps such as WhatsApp, Facebook Messenger, Google Maps and weather tools. O2 is pricing the add-on at £3 per month.

By leveraging Starlink’s satellite infrastructure, O2 can deliver connectivity in remote and rural regions without building additional ground towers. The move represents another step in Starlink’s push beyond fixed broadband and into direct-to-device mobile services.

Virgin Media O2 chief executive Lutz Schuler shared his thoughts about the Starlink partnership. “By launching O2 Satellite, we’ve become the first operator in Europe to launch a space-based mobile data service that, overnight, has brought new mobile coverage to an area around two-thirds the size of Wales for the first time,” he said.

Satellite-based mobile connectivity is gaining traction globally. In the U.S., T-Mobile has launched a similar satellite-to-cell offering. Meanwhile, Vodafone has conducted satellite video call tests through its partnership with AST SpaceMobile last year.

For Starlink, the O2 agreement highlights how its network is increasingly being integrated into national telecom systems, enabling standard smartphones to connect directly to satellites without specialized hardware.
