SpaceX to launch AST SpaceMobile’s first space-based cell towers

Published

on

AST Space Mobile says it has chosen SpaceX to launch its first operational BlueBird satellite after contracting the company to launch BlueWalker 3, its first major prototype.

An SEC filing made around the same time states that AST SpaceMobile will pay SpaceX at least $22.75 million to “adjust” its upcoming BlueWalker 3 launch contract, cover an “initial payment” for the launch of BlueBird 1, and pay the reservation fee for a second launch for BlueBird 2. While only representing three probably ‘launch service agreements,’ the decision sets SpaceX up to be the company’s primary launch provider for a constellation of as many as 243 large communications satellites.

While choosing SpaceX – the most affordable and available launch provider on Earth – is far from unexpected, the satellites SpaceX will be launching for AST are anything but traditional. Driven largely by the technical requirements of AST SpaceMobile’s goal of directly connecting unmodified mobile phones to the internet through satellite in orbit, the company has completely ignored the relatively common satellite design trope of a central ‘bus’ with two solar array ‘wings.’

Instead, AST’s BlueBird satellites will launch with their antennas effectively folded around their ‘bus’ like a giant origami cocoon. Once in orbit, using a fairly elegant extension of normal solar array deployment mechanisms, the satellite’s antenna will slowly unfold and eventually return to its default shape – a giant, flat surface. For a number of reasons, AST SpaceMobile recently decided to halve the total area of its BlueBird satellites, but the new design will still feature an immense antenna with a surface area of about 450 square meters (~4800 square feet). Only the United States’ classified Orion spy satellites likely eclipse the size of the antennas AST wants to deploy in space.

Thanks to those massive antennas, though, AST says its BlueBirds will theoretically be able to “reach over 700 million unconnected people,” though it’s less clear how many users the constellation – or a single satellite – will be able to simultaneously support. Additionally, located in low Earth orbit (LEO), an uninterrupted connection will only be possible once a string of satellites have been launched into roughly the same orbital plane. Until then, the service will be intermittent – a huge boon for emergency communications in remote areas but hard to use for much else in the interim.

BlueWalker 3, a prototype satellite, aims to demonstrate AST SpaceMobile’s relatively exotic satellite design while simultaneously (with any luck) showing that it can connect hundreds or thousands of unmodified phones to the internet as if it were an ordinary cell tower. AST says it has already demonstrated the space-to-ground connection in a clever way by launching what amounts to mobile phone turned into a cubesat and then using that orbital phone to connect to a simulated cell tower satellite back on Earth. Developed for about $70 million, BlueWalker 3 will weigh about 1.5 tons (~3300 lb) and attempt to deploy a smaller but still representative 65-square-meter (~693 sq ft) origami-like antenna.

AST SpaceMobile hasn’t confirmed a launch date and is still working on the satellite prototype but its latest “summer 2022” target suggests it will launch on SpaceX’s Transporter-5 rideshare mission as early as June 2022.

A December 2025 study by casino games aggregator Relum has identified Elon Musk’s Grok as one of the most reliable AI chatbots for workplace use, boasting the lowest hallucination rate at just 8% among the 10 major models tested. 

In comparison, market leader ChatGPT registered one of the highest hallucination rates at 35%, just behind Google’s Gemini, which registered a high hallucination rate of 38%. The findings highlight Grok’s factual prowess despite the AI model’s lower market visibility.

Grok tops hallucination metric

The research evaluated chatbots on hallucination rate, customer ratings, response consistency, and downtime rate. The chatbots were then assigned a reliability risk score from 0 to 99, with higher scores indicating bigger problems.

Grok achieved an 8% hallucination rate, 4.5 customer rating, 3.5 consistency, and 0.07% downtime, resulting in an overall risk score of just 6. DeepSeek followed closely with 14% hallucinations and zero downtime for a stellar risk score of 4. ChatGPT’s high hallucination and downtime rates gave it the top risk score of 99, followed by Claude and Meta AI, which earned reliability risk scores of 75 and 70, respectively. 

Why low hallucinations matter

Relum Chief Product Officer Razvan-Lucian Haiduc shared his thoughts about the study’s findings. “About 65% of US companies now use AI chatbots in their daily work, and nearly 45% of employees admit they’ve shared sensitive company information with these tools. These numbers show well how important chatbots have become in everyday work. 

“Dependence on AI tools will likely increase even more, so companies should choose their chatbots based on how reliable and fit they are for their specific business needs. A chatbot that everyone uses isn’t necessarily the one that works best for your industry or gives accurate answers for your tasks.”

In a way, the study reveals a notable gap between AI chatbots’ popularity and performance, with Grok’s low hallucination rate positioning it as a strong choice for accuracy-critical applications. This was despite the fact that Grok is not used as much by users, at least compared to more mainstream AI applications such as ChatGPT.

Canaccord Genuity analyst George Gianarikas raised his Tesla (NASDAQ:TSLA) price target from $482 to $551. He also maintained a “Buy” rating for TSLA stock over the company’s improving long-term outlook, which is driven by autonomy and robotics. 

The analyst’s updated note

Gianarikas lowered his 4Q25 delivery estimates but pointed to several positive factors in the Tesla story. He noted that EV adoption in emerging markets is gaining pace, and progress in FSD and the Robotaxi rollout in 2026 represent major upside drivers. Further progress in the Optimus program next year could also add more momentum for the electric vehicle maker. 

“Overall, yes, 4Q25 delivery expectations are being revised lower. However, the reset in the US EV market is laying the groundwork for a more durable and attractive long-term demand environment. 

“At the same time, EV penetration in emerging markets is accelerating, reinforcing Tesla’s potential multi‑year growth runway beyond the US. Global progress in FSD and the anticipated rollout of a larger robotaxi fleet in 2026 are increasingly important components of the Tesla equity story and could provide sentiment tailwinds,” the analyst wrote. 

Tesla’s busy 2026

The upcoming year would be a busy one for Tesla, considering the company’s plans and targets. The autonomous two-seat Cybercab has been confirmed to start production sometime in Q2 2026, as per Elon Musk during the 2025 Annual Shareholder Meeting.

Apart from this, Tesla is also expected to unveil the next-generation Roadster on April 1, 2026. Tesla is also expected to start high-volume production of the Tesla Semi in Nevada next year. 

Apart from vehicle launches, Tesla has expressed its intentions to significantly ramp the rollout of FSD to several regions worldwide, such as Europe. Plans are also underway to launch more Robotaxi networks in several more key areas across the United States.

Waymo sues Santa Monica over order to halt overnight charging sessions

In its complaint, Waymo argued that its self-driving cars’ operations do not constitute a public nuisance, and compliance with the city’s order would cause the company irreparable harm.

Waymo has filed a lawsuit against the City of Santa Monica in Los Angeles County Superior Court, seeking to block an order that requires the company to cease overnight charging at two facilities. 

In its complaint, Waymo argued that its self-driving cars’ operations do not constitute a public nuisance, and compliance with the city’s order would cause the company irreparable harm.

Nuisance claims

As noted in a report from the Los Angeles Times, Waymo’s two charging sites at Euclid Street and Broadway have operated for about a year, supporting the company’s growing fleet with round-the-clock activity. Unfortunately, this has also resulted in residents in the area reportedly being unable to sleep due to incessant beeping from self-driving taxis that are moving in and out of the charging stations around the clock. 

Frustrated residents have protested against the Waymos by blocking the vehicles’ paths, placing cones, and “stacking” cars to create backups. This has also resulted in multiple calls to the police.

Last month, the city issued an order to Waymo and its charging partner, Voltera, to cease overnight operations at the charging locations, stating that the self-driving vehicles’ activities at night were a public nuisance. A December 15 meeting yielded no agreement on mitigations like software rerouting. Waymo proposed changes, but the city reportedly insisted that nothing would satisfy the irate residents.

“We are disappointed that the City has chosen an adversarial path over a collaborative one. The City’s position has been to insist that no actions taken or proposed by Waymo would satisfy the complaining neighbors and therefore must be deemed insufficient,” a Waymo spokesperson stated.

Waymo pushes back

In its legal complaint, Waymo stated that its “activities at the Broadway Facilities do not constitute a public nuisance.” The company also noted that it “faces imminent and irreparable harm to its operations, employees, and customers” from the city’s order. The suit also stated that the city was fully aware that the Voltera charging sites would be operating around the clock to support Waymo’s self-driving taxis.

The company highlighted over one million trips in Santa Monica since launch, with more than 50,000 rides starting or ending there in November alone. Waymo also criticized the city for adopting a contentious strategy against businesses. 

“The City of Santa Monica’s recent actions are inconsistent with its stated goal of attracting investment. At a time when the City faces a serious fiscal crisis, officials are choosing to obstruct properly permitted investment rather than fostering a ‘ready for business’ environment,” Waymo stated.
