SpaceX has been unable to catch a break in the last few weeks and CEO Elon Musk says that a Starship Raptor engine test was delayed twice in one day by minor hardware bugs and damage caused by Hurricane Hanna.

Although it quickly devolved into a tropical storm and largely missed the southernmost tip of Texas, where SpaceX has built its Starship factory and test facilities, Hanna caused significant damage just a few dozen miles to the north. Above all else, the flooding caused by Hanna has by far been the worst part of the storm. Boca Chica managed to dodge the bulk of that element but was still hit by heavy rain that lasted for a day or two, drenching everything that wasn’t covered and nearly flooding the only access road.

According to Musk, an unspecified “connector” related to Starship SN5 or the pad supporting it was damaged by Hanna’s glancing encounter with SpaceX’s facilities. The connector was ultimately fixed around 7-8 pm CDT per unofficial webcasts showing technicians working around the rocket after they returned to the pad, but SpaceX’s test window technically closed at 8 pm CDT (01:00 UTC).

Nevertheless, SpaceX must have been able to work with local sheriffs to extend that road closure into the night, and – as promised by CEO Elon Musk – testing restarted around 9:30 pm CDT. About an hour and a half later, Starship SN5 appeared to make it all the way through a partial wet dress rehearsal before its Raptor engine test fire was aborted a second time. Based on four static fires completed by Starship SN4 in May 2020, the rocket could have been just a few minutes away from ignition.

According to Musk, Starship SN5’s fuel (methane) “spin valve” – presumably a valve that opens to allow methane gas to spin up Raptor’s fuel turbopump – failed to open when it was supposed to. To ensure Raptor’s health after three inactive weeks spent installed on Starship out in the elements, SpaceX likely planned what is known as a “spin prime” test directly prior to the static fire. If Raptor successfully spun up its turbopumps, SpaceX would proceed directly into static fire operations without having to detank Starship.

During SN5’s second July 27th static fire attempt, Raptor was unable to start that spin prime test, forcing SpaceX to stand down to diagnose and fix the problem. Musk says that SpaceX will attempt to static fire Starship SN5 again tomorrow (July 28th) – assuming the issue can be quickly rectified.

Musk further noted that some “odd…behavior” was observed in the hydraulic pump powering Raptor SN27’s thrust vector control (TVC). Used to steer a rocket engine, Raptor doesn’t technically need functioning TVC to perform a static fire test on the ground, but it’s an issue that will have to be completely fixed before Starship SN5 is allowed to attempt its first flight test. If July 28th finally sees SN5 successfully ignite its Raptor engine, there’s a chance – however slim – that SpaceX will be able to turn the Starship around for its first hop just a few days later.

SpaceX targets 150Mbps per user for upgraded Starlink Direct-to-Cell

If achieved, the 150Mbps goal would represent a significant jump from the current performance of Starlink Direct-to-Cell.

SpaceX is targeting peak download speeds of 150Mbps per user for its next-generation Direct-to-Cell Starlink service. The update was shared by SpaceX Spectrum & Regulatory Affairs Lead Udrivolf Pica during the International Telecommunication Union’s Space Connect conference.

“We are aiming at peak speeds of 150Mbps per user,” Pica said during the conference. “So something incredible if you think about the link budgets from space to the mobile phone.”

If achieved, the 150Mbps goal would represent a significant jump from the current performance of Starlink Direct-to-Cell.

Today, SpaceX’s cellular Starlink service, offered in partnership with T-Mobile under the T-Satellite brand, provides speeds of roughly 4Mbps per user. The service is designed primarily for texts, low-resolution video calls, and select apps in locations that traditionally have no cellular service.

By comparison, Ookla data shows median 5G download speeds of approximately 309Mbps for T-Mobile and 172Mbps for AT&T in the United States, as noted in a PCMag report. While 150Mbps would still trail the fastest terrestrial 5G networks, it would place satellite-to-phone broadband much closer to conventional carrier performance, even in remote areas. 

Pica indicated that the upgraded system would support “video, voice, and data services, clearly,” moving beyond emergency connectivity and basic messaging use cases.

To reach that target, SpaceX plans to upgrade its existing Starlink Direct-to-Cell satellites and add significant new capacity. The company recently acquired access to radio spectrum from EchoStar, which Pica described as key to expanding throughput. 

“More spectrum means a bigger pipeline, and this means that we can expand what we can do with partners. We can expand the quality of service. And again, we can do cellular broadband basically, cellular broadband use cases, like AI or daily connectivity needs,” he stated.

SpaceX has also requested regulatory approval to deploy 15,000 additional Direct-to-Cell satellites, beyond the roughly 650 currently supporting the system. The upgraded architecture is expected to begin rolling out in late 2027.

Tesla has applied to conduct local Full Self-Driving (Supervised) testing in the city of Jönköping, Sweden.

As per local outlet Jönköpings-Posten, Tesla has contacted the municipality with a request to begin FSD (Supervised) tests in the city. The company has already received approval to test its Full Self-Driving (Supervised) software in several Swedish municipalities, as well as on the national road network.

Sofia Bennerstål, Tesla’s Head of Public Policy for Northern Europe, confirmed that an application has been submitted for FSD’s potential tests in Jönköping.

“I can confirm that we have submitted an application, but I cannot say much more about it,” Bennerstål told the news outlet. She also stated that Tesla is “satisfied with the tests” in the region so far.

The planned tests in Jönköping would involve a limited number of Tesla-owned vehicles. Trained Tesla safety drivers would remain behind the wheel and be prepared to intervene if necessary.

Tesla previously began testing in Nacka municipality after receiving local approval. At the time, the company stated that cooperation between authorities, municipalities, and industry enables technological progress and helps integrate future transport systems into real-world traffic conditions, as noted in an Allt Om Elbil report.

If approved, Jönköping would become the latest Swedish municipality to allow local Full Self-Driving (Supervised) testing.

Tesla’s Swedish testing program is part of the company’s efforts to validate its supervised autonomous driving software in everyday traffic environments. Municipal approvals allow Tesla to gather data in urban settings that include roundabouts, complex intersections, and mixed traffic conditions.

Microsoft has announced a new collaboration with Starlink as part of its expanding digital access strategy, following the company’s claim that it has extended internet connectivity coverage to more than 299 million people worldwide.

The update was shared ahead of Mobile World Congress, where Microsoft detailed how it surpassed its original goal of bringing internet access to 250 million people by the end of 2025.

In a blog post, Microsoft confirmed that it is now working with Starlink to expand connectivity in rural and hard-to-reach regions.

“Through our collaboration with Starlink, Microsoft is combining low-Earth orbit satellite connectivity with community-based deployment models and local ecosystem partnerships,” the company wrote.

The partnership is designed to complement Microsoft’s existing work with local internet providers and infrastructure companies across Africa, Latin America, and India, among other areas. Microsoft noted that traditional infrastructure alone cannot meet demand in some regions, making low-Earth orbit satellite connectivity an important addition.

Kenya was cited as an early example. Working with Starlink and local provider Mawingu Networks, Microsoft is supporting connectivity for 450 community hubs in rural and underserved areas. These hubs include farmer cooperatives, aggregation centers, and digital access facilities intended to support agricultural productivity and AI-enabled services.

Microsoft stated that 2.2 billion people globally remain offline, and that connectivity gaps risk widening as AI adoption accelerates.

Starlink’s expanding constellation, now numbering more than 9,700 satellites in orbit, provides near-global coverage, making it one of the few systems capable of delivering broadband to remote regions without relying on terrestrial infrastructure.
