FCC cancels $900 million award to Starlink

3:07 pm

The FCC today canceled a $900 million subsidy it had awarded to SpaceX in December 2020 as part of a federal program to help establish broadband service in rural communities.

The reasoning for canceling the award given at the link is very unclear. However, since the award a lobbying effort by Starlink’s competitors — teamed up with Democrats in Congress — to cancel the award has been on going. It now seems to have succeeded.

Another clue to explaining this cancellation is timing. The award was announced at the end of the Trump administration, when his appointees controlled the FCC. The cancellation took place during the Biden administration, with the FCC now controlled by Democrats who are increasing revealing themselves to be very hostile to private commercial space in general and Musk and SpaceX in particular.

Nonetheless, it seems absurd to give SpaceX any such subsidy, regardless of the politics. As I said in February 2021:

No one, including SpaceX, should get these funds. SpaceX is proving they aren’t necessary to get the job done (bringing fast internet service to rural communities). Moreover, the federal government really doesn’t have the cash, deep in debt as it is.

Sadly, just because the FCC cancelled its award to SpaceX we should not expect as modern taxpayers that the money won’t be spent. Expect the Biden administration to instead dole it out to its preferred vendors.

Fractures in the Martian northern lowland plains

Fractures in the northern lowland plains
Click for full image.

Cool image time! The photo to the right, rotated, cropped, and reduced to post here, was taken on April 21, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO) of a spot in the Martian northern lowland plains.

Generally the surface of these lowland plains — especially at high latitudes above 30 degrees — tends to appear very water saturated, producing blobby features and what look like mud volcanoes. This picture however features something different, what the scientists have labeled fractures, geological features that appeared caused by dry conditions and sudden quake-like events. The break in the fracture near the top of the photo illustrates why water flow had little if anything to do with its formation. Other fractures in the full image show the same thing. Also the stippled surface along the picture’s right edge also suggest there is little near surface water or ice at this location.

The location, as shown by the overview map below, suggests that water might still have played a part, but only a long time ago.

InSight’s power status holding steady on Mars

9:47 am

InSight's status as of August 9, 2022

Yesterday the InSight science team posted the lander’s ongoing power status, as it has been doing about every week since in June the team announced that they expected power to run out sometime in August, ending the mission.

I have created the graph to the right, showing the data from all those updates, to try to glean the overall trends. The red line indicates the tau level of dust in the atmosphere, essentially telling us how much that dust is blocking light from the Sun. Normally outside of dust season this number should range from 0.6 to 0.7. Since May 17 that dust level has been steadily declining, which thus increases the amount of sunlight reaching the panels.

The blue line marks the amount of power the lander’s panels have been able to produce. The lack of change in this line reveals both good and bad news. The good news is that the power level is holding steady, at a level that allows InSight’s one operating instrument, its seismometer, to continue to function. Should this power level continue to remain stable, that seismometer should be able to operate past August, thus extending the instrument’s life longer than expected.

The bad news is that the power levels are not going up as the dust level is dropping. This suggests that the dust layer on the panels that is preventing them from generating power is actually getting thicker. InSight has still not experienced any puff of Mars’ weak wind capable of blowing dust off those panels. Instead, as the dust settles out of the atmosphere with the end of dust season, some is settling on the panels themselves.

As new updates arrive I will update this graph. Stay tuned. InSight is not yet dead, though the vultures are unfortunately circling overhead.

UK regulators to investigate Viasat-Inmarsat merger

9:03 am

The United Kingdom’s Competition and Markets Authority (CMA) yesterday opened an investigation into the purchase of InMarsat by Viasat, announced in November ’21, to see it that merger would “result in a substantial lessening of competition within any market or markets in the United Kingdom for goods or services.”

This investigation will clearly delay the merger. It also appears somewhat counter-productive, considering that Inmarsat has been having trouble making money in recent years due to the market’s shift from its big geosynchronous satellites to constellations of smallsats in low Earth orbit, such as SpaceX’s Starlink. Viasat meanwhile has been desperately trying to block Starlink because of that very competitive threat.

By merging, these two satellite companies might survive and compete with the new orbital constellations. Otherwise, they might both go out of business, thus reducing competition. It seems the CMA will be shooting itself in the foot if it blocks this merger.

Superheavy prototype #7 and Starship prototype #24 undergo static fire tests

8:41 am

Superheavy #7's first launchpad engine test
Click for original photo.

Capitalism in space: SpaceX engineers yesterday performed static fire tests of both its Superheavy prototype #7 and its Starship prototype #24.

The Superheavy prototype fired one engine, and did so only a few weeks after that prototype experienced an explosive event the launchpad during earlier fueling/engine tests. Yesterday’s engine test was the first time any Superheavy prototype had fired its engines on the launchpad.

The Starship prototype meanwhile fired two engines on a nearby vertical test stand.

SpaceX’s plan is to stack #24 on top of #7 and attempt an orbital launch test that will have the Superheavy prototype land in the Gulf of Mexico while the Starship prototype reaches orbit and then returns to Earth in the Pacific northeast of Hawaii. Based on the company’s normal pace of operations, that flight is probably only weeks away. However, before that flight engineers will have to do a full static fire test of all 33 of #7 engines, and then like do it again with Starship #24 stacked on top.

SpaceX successfully launches 52 more Starlink satellites

7:24 pm

Capitalism in space: SpaceX tonight successfully used its Falcon 9 rocket to launch another 52 Starlink satellites into orbit.

The first stage completed its third flight, landing successfully on a drone ship in the Atlantic Ocean. The fairings also completed their third flight.

The leaders in the 2022 launch race:

35 SpaceX
29 China
11 Russia
6 Rocket Lab
5 ULA

American private enterprise now leads China 50 to 29 in the national rankings, and the entire world combined 50 to 37.

Rocket Lab considering further targets for in-space Photon upper stage

12:12 pm

Capitalism in space: As noted during a speech yesterday by CEO Peter Beck, Rocket Lab is considering further interplanetary targets for its still functioning Photon upper stage, that helped launch NASA’s CAPSTONE mission toward the Moon.

Rocket Lab is continuing to operate Lunar Photon more than a month after it deployed CAPSTONE. The spacecraft is currently about 1.3 million kilometers from Earth, he said, and will swing back to Earth later in the month.

The spacecraft still has 10-15% of its propellant remaining. “As it scoots past Earth,” Beck said, “we’ll have a crack at doing something cool with it and see how far into the solar system we can get with it.”

Rocket Lab hopes to use a future Photon stage to send a probe to Venus, and is using the Photon in space now for engineering tests. It is also selling this technology as a viable cheaper alternative to the typically expensive interplanetary probes.

Debris from Russian anti-sat test causing numerous near Starlink collisions

12:04 pm

According to an official of a company that helps track space junk, the scattered debris from the satellite destroyed by Russia in an anti-satellite test in 2021 has had numerous near collisions with multiple Starlink satellites.

In the Aug. 6 event, Oltrogge said there were more than 6,000 close approaches, defined as being within 10 kilometers, involving 841 Starlink satellites, about 30% of the constellation. It’s unclear how many, if any, of the satellites had to maneuver to avoid collisions.

This conjunction squall was exacerbated by a new group of Starlink satellites. SpaceX launched the first set of “Group 3” Starlink satellites July 10 from Vandenberg Space Force Base into polar orbit, followed by a second set July 22. A third batch of Group 3 satellites is scheduled to launch Aug. 12.

The problem is only going to get worse, as this junk will be in orbit for quite some time.

Northrop Grumman partners with Firefly to make Antares entirely U.S. made

9:00 am

Capitalism in space: Because the Russian invasion of the Ukraine, Northrop Grumman yesterday announced that it has signed a deal with the rocket startup Firefly to replace the Russian engines and Ukrainian-built first stages on its Antares rocket.

Firefly’s propulsion technology utilizes the same propellants as the current Antares rocket, which minimizes launch site upgrades. The Antares 330 will utilize seven of Firefly’s Miranda engines and leverage its composites technology for the first stage structures and tanks, while Northrop Grumman provides its proven avionics and software, upper-stage structures and Castor 30XL motor, as well as proven vehicle integration and launch pad operations. This new stage will also significantly increase Antares mass to orbit capability.

The press release made no mention of launch dates. However, according to Reuters Northrop Grumman has purchased three SpaceX Falcon 9 launches in ’23 and ’24 to get its Cygnus cargo freighter into orbit in the interim and thus fulfill its ISS resupply contract with NASA.

After an earlier Antares failure the company (then Orbital ATK) had hired ULA’s Atlas-5 to launch Cygnus. ULA however is retiring the Atlas-5 after it completes its present full manifest, so this rocket was no longer available. ULA is replacing it with the Vulcan rocket, but that rocket is not yet operational due to delays in the delivery of its Blue Origin first stage engines. Thus, SpaceX was Northrop Grumman’s only viable option.

There is also a certain irony in the hiring of Firefly to replace the Ukrainian first stage. Firefly was saved from bankruptcy by a Ukrainian billionaire, Max Polykov. Though he has been forced to sell off his ownership in the company by the State Department, Firefly would not now exist to take this business from a Ukrainian company had Polykov not provided his financial help.

Russia and China complete launches

8:45 am

Both Russia and a pseudo-commercial Chinese company today completed launches.

Russia used its Soyuz-2 rocket to launch a military reconnaissance satellite for Iran, along with 16 Russian smallsats. The rocket was originally going to launch a South Korean satellite, but that launch was cancelled due to Russia’s invasion of the Ukraine.

In China, the pseudo-company Galactic Energy used its four-stage Ceres-1 rocket to place three Earth observations satellites into orbit. Because three of the rocket’s four stages use solid rocket motors, they were likely reworked from military applications. Thus, Galactic Energy does nothing without the full approval and supervision of the Chinese government. It might have been funded privately, and focused on making profits, but it really owns nothing it builds.

Nonetheless, this was its third successful orbital launch, making it the most successful of these Chinese pseudo-companies. It is also developing a Falcon 9 clone rocket dubbed Pallas-1, which it hopes to launch next year.

The leaders in the 2022 launch race:

34 SpaceX
29 China
11 Russia
6 Rocket Lab
5 ULA

American private enterprise still leads China 49 to 29 in the national rankings, and the entire world combined 49 to 47. A SpaceX Falcon 9 launch later today should strengthen this lead again.

Sri Lanka blocks docking of Chinese spy ship as requested by India

11:47 am

The new Sri Lankan government, at the request of India, has rescinded the permission granted by the previous government that would have allowed a Chinese satellite tracking ship to dock at one of its ports.

In a written request, the Sri Lanka Foreign Ministry told the Chinese Embassy in Colombo not to go ahead with the visit, said an official involved in the process. “The Ministry wishes to request that the arrival date of the vessel Yuan Wang 5 in Hambantota to be deferred until further consultations are made on this matter,” the request says.

Sri Lankan President Ranil Wickremesinghe assured political leaders on Friday that the visit will not go ahead as planned.

The previous government, recently overthrown by a citizen revolt because of its green policies that produced starvation and bankruptcy throughout the nation, had agreed to the docking, changing years of cooperation with India. Apparently the new government has decided to renew that Indian alliance.

India in turn wishes to limit China’s ability to spy on its own satellites and operations in space.
