AST SpaceMobile successfully tests cell-to-satellite calls transmitting video

9:37 am

According to press releases from both Verizon and AT&T on February 24, 2025, each has successfully tested cellphone-to-satellite video calls using the first set of satellites in AST SpaceMobile’s BlueBird satellite constellation. From ATT:

AT&T and AST SpaceMobile have successfully completed a video call by satellite over AT&T spectrum using the BlueBird satellites launched last September. These are the same satellites that will be used to start commercial service.

From Verizon:

Verizon and AST have yet again pushed the boundaries of what can be done with mobile devices by successfully trialing a live video call between two mobile devices with one connected via satellite and the other connected via Verizon’s terrestrial network connection.

The satellites will essentially act like cell towers in space, filling in all dead spots not reached by ground-based towers.

AST’s constellation is competing with Starlink, which has signed T-Mobile for its service. In addition, Eutelsat-Oneweb has just successfully tested using its satellite constellation for the same purpose.

I suspect that in time, when these satellite systems have been thoroughly tested and have become operational, they will allow these phone networks to begin decommissioning their cell towers on Earth, thus reducing their costs significantly and thus lowering the cost to their customers.

Eutelsat-Oneweb uses its satellite constellations to test technology for phone-to-satellite capabilities

9:17 am

The communications company Eutelsat-Oneweb announced today that it has successfully tested the technology that would allow smartphones to use its satellite constellations as orbiting cell towers in order to eliminate dead zones in their ground-based systems.

Based on the press release, it is unclear whether the tests actually included a cell phone.

The trial used Eutelsat OneWeb satellites, with the MediaTek NR NTN test chipset, and NR NTN test gNB provided by ITRI, implementing the 3GPP Release 17 specifications. Sharp, Rhode & Schwarz provided the antenna array and test equipment and the LEO satellites, built by Airbus, carry transponders, with Ku-band service link, Ka-band feeder link, and adopt the “Earth-moving beams” concept. During the trial, the 5G user terminal successfully connected to the 5G core via the satellite link and exchanged traffic. [emphasis mine]

That user terminal might have been a smart phone, or it could have been an engineering test terminal.

Either way, Eutelsat-Oneweb appears to be aggressively trying to enter the competition for cell-to-satellite business, competing with the systems already operational from Starlink and AST SpaceMobile.

China and SpaceX complete launches

7:36 pm

Two more launches today. First China launched a communications satellite into orbit, its Long March 3B rocket lifting off from its Xichang spaceport in the southwest of China. No word on where the rocket’s core stage and four side boosters crashed inside China. Nor has China released much information about the satellite itself.

Next SpaceX placed another 22 Starlink satellites, its Falcon 9 rocket lifting off from Vandenberg in California. The first stage completed its eleventh flight, landing on a drone ship in the Pacific.

The leaders in the 2025 launch race:

23 SpaceX
8 China
2 Rocket Lab

At this moment SpaceX’s 23 launches in 2025 is not far short of being twice as much as the 14 launches completed by rest of the entire world combined. It certainly is outpacing everyone else quite handily.

SpaceX launches 23 Starlink satellites; landing first stage on drone ship in the Bahamas

4:35 pm

SpaceX today successfully placed 23 Starlink satellites in orbit, its Falcon 9 rocket lifting off from Cape Canaveral in Florida.

The rocket’s two fairings completed their 14th and 22nd flight respectively. The first stage completed its 16th flight, landing on a drone ship off the coast of the Bahamas, near Exumas. That landing was the first ever to land in territory of another country. SpaceX negotiated rights to do so from the Bahamas to give it more orbital options launching from Florida.

The 2025 launch race:

21 SpaceX
7 China
1 Blue Origin
1 India
1 Japan
1 Russia

Starlink Falcon 9 launch sets new reuse record for first stage

2:05 pm

Last night SpaceX successfully launched 21 new Starlink satellites, its Falcon 9 rocket lifting off from Cape Canaveral in Florida.

The first stage completed its 26th flight, a new record for the Falcon 9 boosters. That number also exceeded the number of flights the space shuttle Endeavour completed in nineteen years from 1992 to 2011. This SpaceX booster however needed less than three and a half years to do it. Next shuttle record to beat is Columbia’s, which flew 28 times.

China and SpaceX complete launches

12:02 pm

Both China and SpaceX successfully completed launches today.

First, China completed the first launch of its Long March 8A rocket, an upgraded and more powerful version of its Long March 8 rocket. The rocket lifted off from China’s coastal Wencheng spaceport, and put the second batch (number unrevealed) of one of China’s new mega internet constellations.

Along with the basic Long March-8 model and the booster-free tandem configuration, it forms the Long March 8 series of rockets, providing a payload capacity range of 3 tons, 5 tons, and 7 tons to SSO. This significantly enhances China’s satellite networking capabilities for low and medium Earth orbits.

These rockets and the coastal spaceport will also allow China to steadily reduce its reliance on its older family of rockets that use toxic hypergolic fuels and launch from within China.

Next SpaceX launched another 21 Starliink satellites, including 13 with direct-to-cell capabilities, its Falcon 9 rocket lifting off from Cape Canaveral in Florida.

The first stage completed its 18th flight, landing on a drone ship in the Atlantic.

The 2025 launch race:

19 SpaceX
7 China
1 Blue Origin
1 India
1 Japan
1 Russia

Falklands public wants the freedom to choose between OneWeb and Starlink

8:53 am

Even as the Falklands government is demanding its money back from OneWeb for not activating its service on time, it appears the public on those islands has buying and using Starlink terminals, even though it is presently illegal to use it there.

The high level of Starlink usage sparked a successful petition backed by 70% of the island’s population. This petition demanded both a reduction of the £5,400 FIG VSAT licence fee and formal approval for Starlink’s operation in the Falkland Islands.

In response, a Starlink Select Committee – comprising all of the island’s MLAs – convened from July to October 2024. The committee formally endorsed the petition’s demands, and the proposal was subsequently forwarded to the Falkland Islands Government (FIG) for implementation. However, the effective date for this approval has now been delayed until April.

Because Sure International holds an exclusive monopoly telecommunications licence, Starlink’s use in the islands is currently illegal. Nonetheless, this restriction has not prevented the widespread installation of hundreds of Starlink terminals, which remain unlicensed.

Sure International apparently provides internet service though traditional land lines. The cost difference compared to Starlink is considerable, with Starlink being far cheaper and providing much faster speeds. Meanwhile, OneWeb has failed to deliver and is losing this business. By April expect Starlink to be approved.

SpaceX withdraws from process to bring Starlink to South Africa

1:39 pm

In what appears to be directly related to the new South African law that will force the redistribution of private land holdings based on race, SpaceX this week withdrew from a meeting to discuss South Africa’s plan to license Starlink operations.

According to an Icasa spokeswoman, SpaceX notified Icasa on Wednesday evening that it would no longer participate in the oral presentations. The company had already made a written submission, which has not been withdrawn. It’s not clear why SpaceX decided to withdraw from the hearings – the company couldn’t immediately be reached for comment.

The withdrawal by SpaceX follows a post by Musk on his social media platform X that asked President Cyril Ramaphosa why the country has what he called “openly racist ownership laws”.

It is not surprising Musk had the company cancel its plans. Musk has more and more been learning about the corrupt and racist policies of the left, and since South Africa has been ruled for several decades by communists who have now decided to impose DEI quotas on land ownership that require a percentage of white-owned land to be confiscated to give to blacks, he has probably decided there are better places than South Africa to provide Starlink services.
