SpaceX now blocked from Pakistan; OneWeb signs deal to operate in India

9:44 am

Capitalism in space: Two stories this morning suggest that the competition between the internet satellite constellations Starlink and OneWeb is being partly influenced by local politics, with the influence favoring OneWeb and hindering SpaceX.

First, Pakistan ordered SpaceX to stop taking preorders from its citizens for its Starlink system.

The Pakistan Telecommunication Authority (PTA) said in a Jan. 19 news release that “Starlink has neither applied for nor obtained any license from PTA to operate and provide internet services” in the country. The telecoms regulator advised the general public to refrain from pre-booking the service in Pakistan through Starlink or associated websites.

This order follows a similar decree in India. Like India, SpaceX had apparently not been granted a license or permit to take preorders. SpaceX has now been blocked entirely from the subcontinent by the governments of both countries.

Second, OneWeb and Hughes announced a partnership agreement to distribute its internet service in India.

In the statement, OneWeb’s CEO Neil Masterson said the company would partner with Hughes to “offer high-speed, low-latency satellite broadband solutions and contribute to the Digital India vision”. OneWeb’s constellation, he said, would cover the length and breadth of India, from Ladakh to Kanyakumari and from Gujarat to the Northeast and bring secure solutions to enterprises, governments, telcos, airline companies and maritime customers. “OneWeb will invest in setting up enabling infrastructure such as Gateways and PoPs in India to light up the services,” he added.

According to the announcement, OneWeb intends to start offering its service this year.

OneWeb is half-owned by the Indian-based Bharti group. It seems that this connection with India has greased the bureaucratic wheels in that country for OneWeb, allowing it begin offering its services there. It also appears that this same connection with India is likely one reason both India and Pakistan have put a break on SpaceX’s operations.

Flight dates for SpaceX’s next two manned flights to ISS revised

9:24 am

Capitalism in space: A NASA official yesterday announced that the flight dates for SpaceX’s next two manned flights have been firmed up, with the private commercial Axiom AX-1 flight delayed from February 21st to March 31st, followed two weeks later by NASA’s own manned mission on April 15th.

Axiom has also noted that this commercial flight, piloted by a former NASA astronaut and carrying three passengers, will be its only commercial manned flight in ’22.

…Commanded by former NASA astronaut Michael López-Alegría, Ax-1 will only carry private citizens. Each paying $55 million for the privilege, the mission’s three customers are Larry Connor, Mark Pathy, and Eytan Stibbe – all businessmen who’ve respectively amassed multmillion-dollar fortunes in real estate; entertainment and shipping; and military equipment and venture capitalism.

Their Dragon spacecraft will be Resilience, making its third flight.

Axiom’s next private commercial flight has now been delayed until ’23.

Upper stage of ABL rocket explodes during ground test

9:16 am

Capitalism in space: During a ground test of the upper stage of ABL Space Systems RS1 rocket an “anomaly” occurred that caused an explosion, apparently destroying the stage.

No one was hurt, but the company has released few details about what happened. We do not know if the explosion occurred during an engine static fire test, or during a pressure test of the stage’s tanks.

The company’s first launch was in October supposed to happen in December, then was shifted to January. This incident will certainly delay it further.

Ingenuity’s 19th flight delayed due to Martian weather

9:10 am

Because of the early arrival of the fall dust storm season, the Ingenuity engineering team decided to delay the helicopter’s 19th flight on January 5th, rescheduling it to no earlier than January 23rd.

In the days following the flight delay, the dust storm moved over Jezero crater, and we were able to clearly see its effects in both MEDA data and from orbit (Figure 1). Most notable was a sharp drop in air density – about a 7% deviation below what was observed pre-dust storm. This observed decrease would have put density below the lower threshold of safe flight and would have imparted undue risk to the spacecraft. We also observed the effect of dust in the amount of sunlight absorbed by Ingenuity’s solar array, which fell well below normal “clear sky” levels, a drop of about 18%.

Apparently the storm has now dissipated, allowing the new flight date.

Though this flight postponement occurred two weeks ago, today’s update appears to be the first public announcement, which has been typical of the Ingenuity team. They generally announce planned flights just before take-off, but then provide no detailed update on what happened, sometimes for weeks.

Debris apparently cleared from Perseverance’s sample carousel

10:12 am

Mosaic showing the clearing of debris
Click here and here for original images.

Two images taken by one of Perseverance’s cameras and downloaded today appear to show that the bits of debris from the rover’s most recent core sample that had fallen into the sample storage carousel have been dislodged and are now gone.

Those images are above, placed side by side. They were taken a little over an hour apart on January 18, 2022, probably before and after the rover completed two short rotations of the carousel, as planned.

The first image on the left, taken at 12:12:47 local solar time, shows the two small pieces sitting near the bottom inside of the sample storage holder. The second image on the right, taken at 13:20:40 local solar time, shows both pieces gone. There also appears to be less small rubble on the small platform just below this point.

The science team will next take pictures of the ground below, comparing those with pictures taken before the rotations, to see if they can spot this debris and confirm it is completely clear of the rover.

If the debris is gone, as these images suggest, Perseverance will be able to drill another core sample at this location and store it as planned. Expect an announcement by tomorrow or the next day providing more details of this success.

NASA: Russian anti-satellite test in November doubled the threat to ISS

9:17 am

According to a presentation by a NASA official at a conference today, further tracking of the debris from the Russian anti-satellite test on November 15, 2021 suggests that it has doubled the overall chance of a debris collision with ISS.

NASA ISS Program Director Robyn Gatens told a NASA advisory committee today that the November 15, 2021 Russian ASAT test forced the Expedition 66 crew to implement safe haven procedures, closing hatches to parts of the ISS and sheltering in the Soyuz and Crew Dragon spacecraft that could return them to Earth if worse came to worse.

Russia denied the test imperiled the crew, but Gatens said the threat of a piece of debris penetrating the ISS now has doubled to one chance in 25,000-33,000 orbits, versus one in 50,000 orbits prior to the test. The ISS does about 6,000 orbits a year.

It should be noted that, according to these numbers, the overall threat seems quite manageable. Nonetheless, the Russian anti-sat test was entirely irresponsible, especially because it targeted a defunct satellite in an orbit slightly higher than ISS, which means its debris will over time move into ISS’s orbit. The test also violated the Outer Space Treaty, which Russia has signed, which requires all signatories to control what they do in space so that it does not threaten either the persons or property of anyone else.

Chinese pseudo-company preparing first launch of methane-fueled rocket

9:07 am

The Chinese pseudo-private company, Landspace, is apparently prepping its new launchpad and Zhuque-2 rocket for launch in one of China’s interior spaceports.

Satellite imagery and deleted social media postings indicate that work is progressing on a new complex for facilitating methane-liquid oxygen launch vehicles at Jiuquan Satellite Launch Center in northwest China. Timelapse and high resolution satellite imagery show the development near the national Jiuquan center in the Gobi Desert and suggest the presence of a Zhuque-2 test article. A recent, now-deleted article indicates a new flame trench has been completed at Jiuquan.

The article at the link also cites statements by the company’s CEO in November, where he claimed they would launch in the first quarter of ’22. If successful, it would be the first orbital launch of a methane-fueled rocket, beating out both SpaceX’s Starship and Blue Origin’s New Glenn.

The article also says that the company is working on making the first stage reusable, which makes sense in that it will launch from inside China and that first stage if expendable will crash uncontrolled on Chinese territory. A second Chinese pseudo-company, iSpace, also claims it will begin hop tests of its own reusable rocket later this year.

For new readers: I call these companies pseudo because they really are not independent entities, as private companies are in the west. China’s government since 2014 has allowed private investors to create these companies and for the companies to compete against each other for government business, but none of them do anything without the full supervision of the Chinese government. Most have completed their first launches using solid rockets, technology almost always reserved for military use. None could have done so without that government permission and control.

The strategy here of China’s government is nonetheless smart, as the policy is creating competition and thus some innovation within its aerospace industry. The top-down control however will likely prevent these companies from doing anything truly different. Instead, they are apparently latching onto the new ideas, such as methane-fueled rockets and vertically landing first stages, that they have seen demonstrated by the truly independent private companies in the west.

Israel approves Artemis Accords

8:51 am

The Israeli government has apparently agreed to sign the American-led Artemis Accords, making it the fifteenth nation to do so.

While Israel’s foreign ministry has not released an official statement on the issue, local media reports said a signing ceremony involving NASA Administrator Bill Nelson and Israel Space Agency Director-General Uri Oron is expected the week of Jan. 23. ISA will host the 17th Ramon International Space Conference on Jan. 25 as part of Israel’s Space Week.

Once Israel officially signs, the full list of signatures will be as follows: Australia, Brazil, Canada, Israel, Italy, Japan, Luxembourg, Mexico, New Zealand, Poland, South Korea, the United Kingdom, the United Arab Emirates, Ukraine, and the United States.

Since the accords are designed to encourage private enterprise and private property rights in space, both Russia and China oppose them. The lack of both France and Germany to sign at this point suggests the politicians presently in charge of those capitalist countries are reconsidering their commitment to free enterprise.

Russian astronauts locate another leak on Zvezda

8:44 am

According to Russia’s state-run TASS press, Russian astronauts have located what it calls “the last air leak” on the Zvezda module of ISS.

Russian cosmonauts Anton Shkaplerov and Pyotr Dubrov discovered the last air leak location in the International Space Station’s Zvezda module, Roscosmos spokesman Dmitry Strugovets said Tuesday, adding that the leak will be eliminated after special equipment is delivered to the station.

Like most of the other leaks previously found, this one was located in the aft transition chamber where the Zvezda docking port is located, once again suggesting that these leaks are the result of stress fractures caused by age and the more than a hundred dockings that have occurred there since Zvezda was launched more than twenty years ago.

The Russians’ belief that no more leaks will be found is probably based on their decision to reduce, even cease the use of this port. The new Prichal docking hub, which two Russians today are doing a spacewalk to finalize its integration with the station, makes the shuttering of Zvezda’s port possible.

At the same time, the existence of numerous stress fractures in an ISS module is not something to be dismissed lightly, as the TASS article attempts to do. It is akin to cracks in the hull of a submarine, and I don’t know anyone who would be willing to send such a vessel deep underwater.

Boeing and NASA still aiming for a May launch of unmanned Starliner test demo

7:58 pm

Capitalism in space: Boeing and NASA are still targeting a May launch of Starliner’s unmanned test demo flight to ISS, delayed since August because of a valve issue in the service module.

Though they think they have identified and fixed that sticky valve problem, they have also decided to replace the service module for the demo flight, using the module originally planned for the first manned flight that will follow.

SpaceX launches another 49 Starlink satellites

7:14 pm

Capitalism in space: SpaceX tonight used its Falcon 9 rocket to launch 49 Starlink satellites into orbit.

The first stage successfully landed on a drone ship in the Atlantic Ocean, completing its 10th flight. SpaceX now has three four first stages that have completed at least ten flights. (The correction comes from a comment by one of my readers below.)

The 2022 launch race:

3 SpaceX
1 Virgin Orbit
1 China

Launch of Kickstarter campaign for Pioneer game delayed till Feb 1

9:58 am

Lunar colony, 2173
From the proposed Pioneer video game: a lunar base in 2173,
part of the independent nation, United Lunar.

Because of a number of issues related to marketing, Aaron Jenkin yesterday made the decision to delay slightly the start of the Kickstarter campaign to raise funds for developing his video game based on my science fiction book, Pioneer.

Instead of starting today, Aaron has shifted the date back two weeks to February 1st. From the project’s newsletter, just sent out to those who have subscribed:

To be blunt, we’ve had a surprisingly difficult time in the past few weeks getting the word out about our campaign. And I can tell from looking at the results of our efforts so far, we need to grind away a little longer to solidify our success. With that said, we’ve updated Mr. Zimmerman on where we stand, and we’ve plotted the course that we’ll take over the next two weeks to accomplish our mission.

For a number of reasons, Aaron felt he needed another two weeks to ramp up the marketing campaign. While this means his campaign for funds will coincide with my annual February fund-raising campaign for Behind the Black, we decided to go ahead anyway, figuring the synergy of both might work to our advantage, making 2+2=6.

If you, as a fan of my writing, are thinking of donating to this video game project, I strongly urge you to subscribe to the newsletter. You can do so at the game’s webpage, PioneerSpaceGame.com. Aaron uses the subscription numbers as a guide to measure interest.
