Ingenuity completes 21st flight on Mars

3:54 pm

Overview map
Click for interactive map.

According to a tweet today from JPL, the Mars helicopter Ingenuity has successfully completed its 21st flight on Mars, traveling 1,214 feet in two minutes and nine seconds at an average speed of 12.6 feet per second.

The red dot on the map to the right shows Perseverance’s location as of today. The green dot indicates Ingenuity’s position before the 21st flight. Since neither the Perseverance nor the helicopter teams have posted any updates describing the 21st flight, it is difficult to indicate a precise location for its landing site. All we know is that the helicopter is supposed to fly to the northwest, cutting across the rougher region while the rover follows the tan dotted line around that rough region, with both targeting the delta to the northwest.

As a guess, I have placed a black dot about 1,200 feet to the northwest.

Russia to lose seventeen launches due to Ukraine sanctions

9:43 am

This article at Space News today provides a nice summary of the number of launches that Russia’s Roscosmos will likely lose in the next three years due to the break off of commercial operations against that country because of its invasion of the Ukraine.

According to the article, Russia will lose sixteen launches. The list however misses one South Korean satellite scheduled for launch on an Angara rocket later this year. The total breakdown of this lost business is therefore as follows:

13 launches lost in 2022
3 launches lost in 2023
1 launch lost in 2024

The entities impacted are as follows:

Government launches:
Europe: six launches in ’22 and ’23, totaling eight satellites
South Korea: two launches in ’22
Sweden: one launch in ’22

Commercial launches:
OneWeb: six launches in ’22, totaling 199 satellites
Axelspace: one launch, totaling four satellites
Synspective: one launch

If the Ukraine War were to end today, it is possible that most of the government launches would be reinstated. The commercial companies however are almost certainly going to find other launch providers, no matter what. OneWeb for example is hardly going to trust its business to Russia after that country cancelled the launches and (at least at this moment) has confiscated the already delivered satellites.

If the war continues for another two or three months, then all this business will vanish for good, as alternative rocket companies will likely be found.

This list however does reveal one interesting fact. It appears that very few private companies have been interested in buying Russian launch services, with or without the Ukraine War. Most of Russia’s international customers have been other governments. Even OneWeb falls partly into this category, as it is half owned by the United Kingdom.

This fact suggests that Russia’s product has simply not been competitive against the new commercial market. The governments meanwhile probably had political motives in addition to economics to throw their business Russia’s way. Those political motives are now gone.

Software company aims to launch 250 satellite weather constellation

9:06 am

Capitalism in space: Acme Atronomatic, a software company that developed the MyRadar weather app that has been downloaded 50 million times, is now planning to launch 250 satellite weather constellation, with the first test satellites scheduled for launch in April.

The satellites, scheduled to launch in April on a Rocket Lab Electron from New Zealand, are designed to test and validate hardware for Orlando, Florida-based Acme’s Hyperspectral Orbital Remote Imaging Spectrometer (HORIS) constellation.

Environmental data captured by the HORIS constellation will be paired with artificial intelligence and machine learning to create data-fusion products for the company’s government and commercial customers. Acme also intends to draw on data and imagery from the HORIS constellation to enhance its MyRadar weather app.

The first batch of Acme satellites set to launch in April are PocketQubes, satellites measuring 5 centimeters on each side. The “batch consists of our own satellite and two others that we have informally helped design and build,” Acme CEO Andy Green told SpaceNews by email. “We’re mostly focusing on the primary satellite, MyRadar1,” which is a HORIS constellation prototype.

Private weather satellites like this are the future, rather than government-built satellite, which has been the norm for sixty years. That shift is also apparently being encouraged by Congress, which the House has passed and the Senate is considering. In it NOAA’s budget to build its own weather satellites was trimmed by about 25%, from the requested $1.68 billion to $1.29 billion.

This trim is hardly painful to NOAA’s weather satellite program, which remains well funded. It does indicate however that our spendthrift Congress is interested in ways to save money in this area.

More thumbprints on Mars!

1:22 pm

Thumbprints on Mars
Click for full image.

Cool image time! Among the many strange and unexplained geological features that scientists have identified on Mars, the thumbprint feature is one of the most intriguing. The photo to the right, cropped and reduced to post here, is a fine example, and was taken on September 10, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The thumbprints are the lighter splotches, and are generally found near curved ridges located mostly in Martian lowlands. All appear to have crater-like features in them, though these craters are not impact craters, but likely (though not confirmed) caused by some form of underground eruption, be it mud, ice, lava or something else. Though scientists do not yet really understand the process that formed the thumbprints, the data strongly suggests that they formed in connection with glacial events. From this 2003 paper [pdf]:

TT [thumbprint terrain] as well as the associated trough systems were formed by a glacial mechanism. [Elevation] data show that the trough systems consistently lie topographically above the TT; this implies that if they were they formed by the same glacier, the troughs must have formed before the glacier retreated and formed the TT.

The splash apron around the crater near the bottom of the photo supports the glacial theory, implying the presence here of underground ice.

Scientists have also theorized wind processes and cinder cones as explanations for these features.

These particular thumbprints are located, as shown in the overview map below, in the same general area as a previous cool image of thumbprints, from April 2019.

Virgin Orbit signs deal to launch Welsh-built satellite from Cornwall in ’22

9:17 am

Capitalism in space: While competing spaceports are now being constructed in Scotland and hope to launch this year, Virgin Orbit yesterday signed a deal with the Wales company Space Forge to launch its satellite from Cornwall, England, in ’22.

Because Virgin Orbit is already operational, while the rockets planned for the two Scottish spaceports in Shetland and Sutherland are still being developed, it appears that Cornwall will win the race to complete the first launch from UK soil in more than a half century.

Space Forge’s business plan is in itself most intriguing.

Space Forge recently announced that, along with partners, it is developing a world-first service incorporating both launch and return of a new small class of vehicle – the ForgeStar – that can be deployed from conventional launchers to provide rapid, reliable and reusable in-space infrastructure. This inaugural mission will see Space Forge’s ForgeStar-0 platform launched for the first time and will test future return from space technology.

Aiming to unlock the next steps on the path to market expansion, dedicated in-space manufacturing, coupled with proof of reliable return, will allow Space Forge to leverage the benefits of the space environment, namely: microgravity, vacuum, and temperature, to create products impossible to manufacture on Earth.

How exactly this satellite will safely return its space-manufactured goods is not yet clear, but if it does so successfully Space Forge will have created a product that at present would be unique. While you can now get your products back from ISS, such a process is very complicated and not very cost effective. Space Forge, if successful, would simplify that process, allowing customers to launch, manufacture products in space, and get those products back, all in one package.

Blue Origin expands its rocket engine factory in Alabama

9:04 am

Capitalism in space: Blue Origin yesterday revealed that it is hiring 300 more engineers and expanding the rocket engine factory in Alabama in order to produce flight worthy BE-3 and BE-4 engines.

Blue Origin in Huntsville spent the pandemic supporting the company’s main engine plant in Kent Washington with parts for the company’s BE-3 and larger BE-4 engines, [site lead Nathan] Harris said. “We are now actually in the process of building our first set of complete engines through our facility,” he said. Those first engines will be produced this year.

…“We’re getting very close,” Harris said. “They’re still doing quite a bit of retrofitting. As you learn, anytime you retrofit something that’s over 60 years old, it takes a little bit more and there’s a little bit more that you unearth that was undiscovered.”

Harris said he expects to be testing the BE-3 “in the next couple of months followed shortly by the BE-4.” [emphasis mine]

This may be good news for both ULA’s Vulcan rocket as well as Blue Origin’s own New Glenn rocket. Both need the BE-4 engine, and both have been delayed years because it has not been ready on time. While the engine problems appear to have been resolved, Blue Origin had not put any thought into developing a practical and affordable manufacturing process that would allow it to build enough engines to serve both itself and ULA.

This expansion at the engine factory suggests the company is finally moving into its production phase. The highlighted sentence above however also tells us that the first flight worthy BE-4 engines are still months away, which will further delay launch of Vulcan and New Glenn. It is now certain that neither will launch this year, putting both rockets more than three years behind schedule.

UK bans all space-related exports to Russia

8:52 am

In response to Russia’s invasion of the Ukraine, the United Kingdom yesterday announced new sanctions, banning all space-related exports as well as increased sanctions on aviation.

For Russia, this component of these new space sanctions might be the most painful, should something go wrong on one of its launches:

The space export ban includes all related services, including insurance or reinsurance services, U.K. officials said. “This means cover is withdrawn on existing policies and UK insurers and reinsurers will be unable to pay claims in respect of existing policies in these sectors,” wrote in the statement.

This restriction also means that any satellite customers will not be able to claim damages. Thus, customers like South Korea, which still has two launches planned on Russia rockets, will lose everything if the launch fails. Because of this, it is almost certain that it will cancel these launches,

Georgia voters kill Camden spaceport project

9:41 am

The residents of Camden County in Georgia yesterday voted by a margin of 72% to 28% to end the county’s project to build a project there.

There are hints that county officials might still try to proceed, having already spent more than $10 million on the project. There are also strong indications that if they do, they will be blocked legally on many fronts.

What this vote suggests is that Americans continue to be uninterested in more commerce, and are easily convinced to put environmental claims first in any political battle. The opponents of the spaceport had said that the spaceport threatened local wildlife — something that clearly doesn’t happen based on more than a half century of data at Cape Canaveral — and the voters in Camden were quick to agree. The voters also probably had a bit of not-in-my-backyard behind their vote as well.

Whether Camden would have succeeded as a spaceport of course is unknown. There are a lot of such facilities being proposed and built, and it is unclear if their number fits the actual launch demand.

SpaceX successfully completes 10th launch in ’22

9:25 am

Capitalism in space: SpaceX this morning successfully placed 48 Starlink satellites into orbit, using its Falcon 9 rocket.

The first stage landed successfully, completing its fourth flight. The fairings were new.

SpaceX continues to maintain a one-launch-per-week pace in ’22, suggesting it will succeed in completing more than 50 launches this year, as predicted by the company.

The leaders in the 2022 launch race:

10 SpaceX
5 China
2 ULA
2 Russia

The U.S. now leads China 15 to 5 in the national rankings. Note that Russia had predicted it would complete about 27 launches in ’22. With the loss of all of its international customers due to its invasion of the Ukraine, that number is likely cut by two-thirds. If Russia completes more than a dozen launches this year we should be surprised.

Monitoring one glacier flowing off a mesa in Mars’ glacier country

1:28 pm

Vicous glacial flow on Mars
Click for full image.

Today’s cool image takes us back to the mesa in Mars’ glacier country that first clued me in on the prevalence of ice in the Martian mid-latitudes. The photo to the right, rotated, cropped, and reduced to post here, was taken on November 13, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), and shows a viscous flow coming down from a hollow on that mesa’s southern wall.

The new image has likely been taken to see if anything has changed since the previous image was taken in 2014. Based on the resolution published at the MRO website, nothing seems to have changed, though with more sophisticated software higher resolution versions of the images are available that might show some changes.

In my first post about Mars’ glacier country in December 2019, this flow was one of four that I featured coming off this same 30-mile wide mesa, as shown by the first overview map below.

Local Texas state/city politicians pressure congressmen to get Starship approved by FAA

11:42 am

Local state/city politicians from Brownsville are applying pressure on their local congressmen to get the FAA to approve its environmental reassessment of SpaceX’s Starship facility in Boca Chica approved.

Asked if the BND [Brownsville Navigation District] Board of commissioners had made its position known to Reps. Vela and Gonzalez, Lopez said: “Actually, right now, we are in talks with both of them. We want them to help. It is a huge economic impact, having SpaceX here. It makes the Rio Grande Valley and in this case Brownsville more lucrative. It gives global attention to our city, which is something we have needed for a long, long, time.”

A reporter put it to Lopez that the City of Brownsville is hoping to attract thousands of tourists once SpaceX starts sending rockets to the Moon and Mars. “It would be a tremendous loss if we lose that,” Lopez said.

Both Congressmen are members of the Democratic Party, so I doubt seriously if they care that much for the economic benefits brought to Brownsville by SpaceX, no matter what they say in public. For Democrats nowadays it is environmental matters that trump all other issues, and so it would shock me if either Vela or Gonzalez buck their party’s agenda to pressure the FAA to approve the environmental reassessment.

However, the November elections are looming, and the polls do not look good for Democrats. If the FAA rejects the reassessment prior to that election and demands that a full environmental impact statement be written, something I now fear will happen because the FAA cannot get NOAA and the Interior Department to sign on, SpaceX will almost certainly shift its Starship operations to Florida. An impact statement would take years to complete, a delay that SpaceX cannot afford. Such a sequence of events would likely do great harm to the reelection campaigns of both Democrats.

I thus now wonder if the Biden administration will force the FAA to continue delaying its decision, month-by-month, until after that November election, thus allowing these Democrats to mouth support without risking anything.

We shall know I think before the end of the month, which is presently the FAA’s announced target date for making a decision. I am willing to bet they delay again, for the fourth time.

Iran launches military satellite

8:46 am

The new colonial movement: It appears that Iran has successfully launched a small military satellite into orbit, Noor-2, though exactly when remains unclear.

IRGC [Islamic Revolutionary Guard Corps] said the Noor-2 satellite reached a low orbit of 500km (310 miles) above the Earth’s surface on the Ghased satellite carrier, state-run Islamic Republic News Agency (IRNA) reported. It described the Ghased as a three-phase, mixed-fuel satellite carrier.

IRGC did not immediately release photos or video of the launch. Putting the second satellite in space would be a major advance for Iran’s military.

The Ghased or Qased rocket uses a mobile launcher design, and was used for Iran’s previous successfully launch in 2020.

In confirming the launch, U.S. Space Command officials called the satellite nothing more than “a tumbling webcam in space,” suggesting it is not very sophisticated. At the same time, the first stage of Qased is essentially a ballistic missile. To be able to use this mobile launcher to get anything into orbit means that same mobile launcher, without the upper stage, could deliver missiles anywhere on Earth, and do so in a manner that is undetectable prior to launch.

This launch, the first for Iran in 2022, does not change the 2022 launch race leader board:

9 SpaceX
5 China
2 Russia
2 ULA

The U.S. leads China 14 to 5 in the national rankings.

Fractured terrain on Mars

1:39 pm

Fractures on Mars
Click for full image.

Today’s cool image, which at first glance does not seem so puzzling, actually falls into my “What the heck?” category of baffling Martian geology. The picture to the right, cropped and reduced to post here, was taken on January 15, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). Labeled “Avernus Cavi fractures”, it shows what resembles the well-documented chaos terrain seen in many places on Mars, where erosion over eons along fault lines creates mesas with random criss-crossing canyons.

The problem is that this location is practically on the Martian equator, and chaos terrain tends to be found in the mid-latitude bands where there are many glaciers, suggesting the cyclical waxing and waning of those glaciers is what causes the erosion. Here at the Martian equator the terrain is very dry. No glaciers.

Moreover, note the higher mesa near the top center. Its flat top suggests that once this terrain was covered with an even higher layer of material, almost all of which was stripped away evenly everywhere, except where that mesa sits. As an amateur geologist I can’t think of any sequence of events that would do such a thing. I suspect professionals might have problems themselves.

Then there are the small parallel ridges. They suggest dunes, especially inside the depressions where sand and dust can get trapped. On the mesa tops however these ridges are more mysterious. Why for example are they aligned with the small ridge in some hollows, but not others? They in many ways remind me of the ridges in this earlier “What the heck?” cool image, also right on the equator.

The overview map below provides some help, though not much.

Bahrain signs Artemis Accords

8:57 am

Bahrain announced today that it has signed Artemis Accords, making it the second Arab country, after the United Arab Emirates (UAE), to do so.

The full list of signatories, now seventeen: Australia, Bahrain, Brazil, Canada, Israel, Italy, Japan, Luxembourg, Mexico, New Zealand, Poland, Romania, South Korea, the United Kingdom, the United Arab Emirates, the Ukraine, and the United States.

In the past week both Bahrain and Romania have joined the accords. The timing suggests both actions might have been triggered by the Ukraine War. Russia opposes the Artemis Accords, and for Romania, a former Soviet block nation, and Bahrain, an Arab nation, to make such announcements so quickly after Russia’s invasion of the Ukraine suggests both are signalling their willingness to ally themselves against Russia.

For this western alliance in space to be complete however it will require that France and Germany as well as more members of the European Space Agency (ESA) to sign on. Before Russia’s invasion these two nations as well as other ESA partners were considering allying themselves with either Russia or China (which also opposes the accords) in future space endeavors. Such an alliance would have prevented them from signing the accords.

The Russian invasion has almost certainly ended any chance these European nations will partner with Russia in space. Thus, it is very likely Russia’s invasion will force them back into a more firm space alliance with the U.S., and get them to sign the accords. If the American State Department has any competence (something we should not expect) it will be jumping on this situation and ramping up its pressure on Europe to sign on.

Astra completes investigation into February 10th launch failure

8:44 am

Capitalism in space: Astra today released the results of its investigation into its February 10th launch failure, confirming that the failure occurred because the improper separation of the fairings on the upper stage.

Through their analysis, Astra confirmed that the payload fairing on LV0008 failed to separate properly prior to upper stage engine ignition due to an electrical issue. The five separation mechanisms that are present in the Rocket 3 fairing were triggered in an incorrect order, resulting in unexpected fairing movement that caused a disconnection in the electrical wiring. This meant that one of the five separation mechanisms did not receive the command to open, thereby preventing the fairing from separating completely.

Upon further investigation, Astra narrowed the root cause of the fairing separation issue down to an error in the electrical harness engineering diagram for the separation mechanisms. The harness was built and installed as specified by the drawing and installation procedures, but an error in the drawing itself led to two of the five harness channels being inadvertently swapped.

In addition, the company identified a software problem “that left the upper stage engine, Aether, unable to utilize its thrust vector control (TVC) system – which allows the engine to gimbal and maneuver the vehicle.”

The company states that both issues have been corrected, and is now targeting March 13 for its next launch, taking place from Kodiak, Alaska, and only carrying a test dummy payload that will not be released from the upper stage. Thus, this test launch will be similar to the company’s only orbital launch on November 19, 2021.

Astra’s fast investigation, fix, and determination to launch again quickly speaks well of the company. Why however it doesn’t test its deployment system with a dummy satellite on this next test launch is somewhat puzzling, especially since it would be very easy to release that dummy into an orbit that quickly decays and burns up in the atmosphere.

Chinese rocket stage impacts Moon

3:56 pm

What is believed to be an abandoned upper stage from a Chinese launch in 2014 is now believed to have impacted the Moon’s far side, as predicted by the estimates of its orbital mechanics.

None of this story is certain, other than amateur astronomers had identified an abandoned uppers stage that they calculated would hit the Moon on March 4th. While the data strongly suggests it was an upper stage from a Chinese launch, that is not confirmed. And so far we do not have confirmation of the impact either. Expect images identifying the impact site from Lunar Reconnaissance Orbiter (LRO) in the next few months.

UK rocket startup Skyrora badly impacted by the Ukraine War

9:16 am

The smallsat rocket startup Skyrora appears to be badly impacted by the Ukraine War, since half its employees work in the Ukraine and the founder of this United Kingdom company is Volodymyr Levykin, a Ukrainian entrepreneur.

Skyrora, headquartered in Edinburgh, Scotland, has about 80 employees in Dnipro, working on research and development of new manufacturing methods and materials, Levykin said.

“From day one, the priority for everyone in Ukraine was the family, then the country and then the company,” said Levykin, who comes from a small town near Dnipro. “And that’s what I told our team. Some of our people managed to move somewhere away from Dnipro, but the majority are staying there and showing significant resilience during this challenging time.”

It more and more appears that one of the biggest fallouts from the Ukraine War will be the destruction of that country’s aerospace industry. From the article at the link:

The Ukrainian space community will watch the developments in Dnipro anxiously. The rocket research and manufacturing facilities, worth billions of dollars, could not only fall into Russian hands but also face irreparable destruction, Ukraine’s former space chief Volodymyr Usov told Space.com in an earlier interview. Due to the amount of toxic rocket fuels and other chemicals, a rocket strike at Yuzhmash and Yuzhnoye could also cause a major environmental disaster, Usov said.

Russia certainly wants to recapture these space assets without damaging them, but that might not be possible. And even if this happens, any partnerships between western and Ukrainian aerospace companies — such as Skyrora’s — will vanish, and will likely not be renewed after the war ends. No commercial company is going to risk any investment with Russia for many years.

Confirmed: Tomorrow’s OneWeb launch on Soyuz-2 rocket cancelled

8:57 am

Russia’s state-run press today confirmed that the launch tomorrow of another 36 OneWeb satellites on a Soyuz-2 rocket from Baikonur has been cancelled.

The decision was announced by Roscosmos head Dmitry Rogozin.

He also instructed to stop preparations for the launch of British OneWeb communications satellites from three spaceports. “All the launches from all Russian launch pads in Kourou, in Baikonur and at the Vostochny Cosmodrome involving the OneWeb company are to be stopped,” the Roscosmos CEO said.

Rogozin has already said that Russia will not refund OneWeb any money it paid for any of the cancelled launches. Nor will Russia return the OneWeb satellites in Kazakhstan to OneWeb.

Meanwhile, it appears that OneWeb is aggressively searching for new launch alternatives.

“We’re looking at U.S., Japanese and Indian options,” Chris McLaughlin, OneWeb’s chief of government, regulatory affairs and engagement, said March 3. “But in the first instance, we’re pointing to Ariane and saying you still owe us a number of launches.”

This statement implies that OneWeb is trying to get Arianespace to pick up the cost of any launches where Russia has been paid but will not launch. This way OneWeb won’t have to pay twice for the launch. This strategy will only work if the partners in the European Space Agency, which owns Arianespace, decide to cover OneWeb’s losses to Russia, which makes this a political decision.

Russia blocks future rocket engine sales to U.S.

1:45 pm

Dmitry Rogozin, head of Roscosmos, today announced that Russia will no longer sell any rocket engines to U.S. companies.

The head of Roscosmos, Dmitry Rogozin, announced the new policy in an interview with the Russia 24 TV channel. “Today we have made a decision to halt the deliveries of rocket engines produced by NPO Energomash to the United States,” Rogozin said in the interview, according to Russia’s state press site Tass. “Let me remind you that these deliveries had been quite intensive somewhere since the mid-1990s.” Rogozin also added: “Let them fly on something else, their broomsticks, I don’t know what,” according to Reuters.

Russian engines are used on two American rockets, ULA’s Atlas-5 and Northrop Grumman’s Antares. The Atlas-4 however is being phased out, and has already received all the engines it needs for all of that rocket’s remaining flights. ULA plans to replace it with its new Vulcan rocket, using Blue Origin’s (long delayed) BE-4 engine.

Antares however is a more serious issue. Northrop Grumman uses this rocket to launch Cygnus freighters to ISS. It depends on two Russian engines for its Ukrainian-built first stage. The Ukraine War now probably makes building more Antares rockets impossible, which means at some point Northrop Grumman will no longer be able to supply ISS with cargo using Cygnus. Furthermore, NASA’s plan to use Cygnus’ engines to maintain ISS’s orbit will be impacted if Cygnus launches to ISS cease.

There is an option, though it too has issues. ULA has already launched one Cygnus to ISS using its Atlas-5. Though this rocket is going away, ULA could probably use its Vulcan instead — assuming Blue Origin finally gets the BE-4 engine operational so that Vulcan can finally launch.

Overall, Russia’s decision might cause a temporary blip in the American space effort, but if the government doesn’t get in the way I think that competition will force a solution. As Aesop said, necessity is the mother of invention.

The layered Martian history exposed in Valles Marineris

12:28 pm

Overview map

The layers in Valles Marineris
Click for full image.

Cool image time! Like the Grand Canyon in the United States, Mars’ largest canyon, Valles Marineris, appears to have been carved out of a layered terrain, thus exposing those many layers in the walls of the canyon.

Valles Marineris, however, is much much larger than the Grand Canyon. You could fit dozens of Grand Canyons inside it and hardly fill it. Yet, its walls have the same layered look, suggesting that in Mars’ long geological history, first came many events that laid down new layers time after time, followed by a long period when the laying ceased and other events carved out the canyon to its almost 30,000 foot depth (which by the way is also about six times deeper than the Grand Canyon).

Today’s cool image to the right, cropped and reduced to post here, was taken on September 5, 2021 and shows a terraced terrain on the floor of Candor Chasma, one small side canyon of Valles Marineris that is still much larger than the Grand Canyon. The black dot in the overview map above indicates its location. I roughly estimate the elevation difference between the high and low spots in the picture is about 3,000 feet, a difference that while two-thirds that of the depth of the Grand Canyon is almost unnoticeable within the depths of Valles Marineris.

This layering is probably the canyon’s most important geological feature. See these previous cool images here and here for other examples. When geologists finally arrive on Mars and can begin dating these layers in detail they will likely reveal the planet’s entire geological history, going back five to six billion years.

Most of the layers are probably volcanic flood lava laid down by repeated eruptions from the giant volcanoes to the west. In between and within however will be deposits from the Martian atmosphere, telling us its composition and thickness. All told, the layers of Valles Marineris will likely unlock almost all of the most basic secrets of Martian geology.

We merely have to go there to find out.

Launch of two South Korean satellites threatened by Russia’s Ukraine war

10:02 am

According to South Korean officials, the launch later this year of two new home-built satellites on Russian rockets is now unlikely because of the sanctions imposed because of Russia’s invasion of the Ukraine.

South Korea’s CAS500-2 remote sensing satellite is set to launch in the first half of this year on a Russian Soyuz rocket from Russia’s Baikonur Cosmodrome in Kazakhstan. South Korea’s KOMPSAT-6 multipurpose satellite, equipped with synthetic aperture radar (SAR), is due to launch in the second half of the year on a Russian Angara rocket from Plesetsk Cosmodrome in northern Russia.

“For now, nothing has changed to the plan,” Korea Aerospace Research Institute spokesman Roh Hyung-il told SpaceNews. “We are taking a close look at how the situation unfolds because it could have a significant impact on our missions.” He admitted that it’s “very likely” that the satellites won’t be launched as planned.

Those officials also said that losing Russia as a launch option will be a “serious blow” to South Korea’s entire space effort. I find that puzzling. There are plenty of other rocket companies now available. Why South Korea feels a need to depend on Russia seems short-sighted.

Shetland spaceport gets third launch customer

9:52 am

Capitalism in space: The United Kingdom’s Shetland spaceport, SaxaVord, announced today that it has signed a third launch customer, the smallsat rocket startup Venture Orbital Systems.

Venture Orbital Systems (VOS), a developer of micro launchers and rocket engines based in Reims, France, plans to use the site at Unst as part of its aim to reach 15 launches of its Zephyr rocket by 2026 and 40 by 2030.

The new spaceport, presently under construction, already has ABL as a future rocket compan. ABL, mostly owned by Lockheed Martin, hopes to launch before the end of the year.

The UK’s has a second spaceport under construction in Sutherland, Scotland. It will be interesting to see if both can garner enough business to prosper.

Former CEO of Virgin Galactic sued over his pump-and-dump stock sale

9:44 am

Buyer beware: Chamath Palihapitiya, who recently stepped down as CEO of Virgin Galactic, has been sued by some of the company’s stockholders for using his insider position to pump-and-dump his stock while keeping vital information secret illegally.

The complaint, filed on behalf of Virgin Galactic to seek damages from its directors and officers, also alleges that founder Richard Branson pocketed $301 million by dumping his shares while the stock price was “artificially inflated.”

Leaders of the company were well aware of defects in its spacecraft three years before they were publicly disclosed last year, according to the complaint filed in federal court in Brooklyn, New York.

It is unclear from the article whether Branson is being sued as well.

Satellite photos suggest Iran had a launch failure with rocket explosion on launchpad

9:38 am

Based on new satellite photos, it appears that an attempt by Iran to launch a satellite failed this week when the rocket exploded on the launchpad.

Before and after images taken by imagery satellites from two different private companies, Maxar and Planet Labs, suggest the incident likely occurred around February 26th.

Satellite images from Maxar Technologies seen by The Associated Press show scorch marks at a launchpad at Imam Khomeini Spaceport in Iran’s rural Semnan province on Sunday. A rocket stand on the pad appears scorched and damaged, with vehicles surrounding it. An object, possibly part of the gantry, sits near it.

Successful launches typically don’t damage rocket gantries because they are lowered prior to takeoff. Iran also usually immediately trumpets launches that reach space on its state-run television channels, and it has a history of not acknowledging failed attempts.

The news reports claims that the failed rocket was Iran’s Zuljanah rocket, which uses solid rocket motors for its lower stages. Zuljanah has never made orbit, having been unveiled one year ago after a single suborbital test flight.

OneWeb scraps further launches from Russia

9:12 am

OneWeb’s board of directors has voted to cancel all further launches of its satellites from Russia, refusing to meet Russia’s demand that the United Kingdom divest its half share in the company.

On Thursday, OneWeb said the company’s board had voted to suspend all launches from Baikonur, Kazakhstan, where the Russian spaceport operated by Roscosmos is based.

OneWeb didn’t elaborate on the vote. But the UK’s Business and Energy Secretary, Kwasi Kwarteng, said his government had refused to divest from OneWeb, which received funding from British authorities in 2020 to stave off a bankruptcy. “The UK Government supports OneWeb’s decision,” Kwarteng tweeted on Thursday. “In light of Russia’s illegal and unprovoked invasion of Ukraine, we are reviewing our participation in all further projects involving Russian collaboration,” he added.

OneWeb hasn’t commented on the company’s contingency plans. But it’s almost certainly looking for a new launch partner. Russia’s Roscosmos previously helped OneWeb send up 428 of 648 satellites for its internet system, which is designed to serve enterprise users.

This decision, combined with Russia’s decision to suspend further Soyuz-2 rocket launches from French Guiana, essentially ends Russia’s partnership with Arianespace. It also likely ends for many years Russia’s place in the international launch market. OneWeb and Arianespace were its last remaining international customers, and their business is now gone. Even if the Ukraine War was settled today, I suspect neither would wish to renew their business with Russia.

As for OneWeb, it has a number of options in the growing launch market, with Arianespace’s rockets its most likely choice. Financially, the delay hurts them in two ways: First, they have paid Russia for a number of launches already, and Russia has said it will not refund the money. Thus, those launches will cost twice as much. Second, the delay hurts them in their effort to compete with SpaceX’s Starlink constellation.

Martian crater overwhelmed by glacier?

Martian crater overwhelmed by glacier?
Click for full image.

Cool image time! The photo to the right, rotated, cropped, and reduced to post here, was taken on January 28, 2022 by the high resolution camera on Mars Reconnaissance Orbiter. It shows what the science team labels a “modified crater.”

What I see is an old crater almost completely covered by glacial material. That material however is also very old, as there are numerous small craters on its surface, enough that it must have been here for a long time. Its cracked surface also suggests this glacier is very old.

Thus, while we might have ice here, buried by a thin layer of dust and debris to prevent it from sublimating away, it must be very old ice. The many climate cycles caused by the extreme swings in Mars’ rotational tilt, from 11 to 60 degrees, have apparently not caused this ice to ebb and flow very much.

Might it therefore not be ice, but hardened lava?

The location, as shown by the overview map below, provides some context, but only makes this mystery more puzzling.

Sunspot update: The Sun rages on

10:54 am

Time for my monthly sunspot cycle update, where I take NOAA’s monthly graph showing the long term trends in the Sun’s sunspot activity, and annotate it with additional data to provide some context.

The trend of sunspot activity exceeding the predictions continued in February. While the increase in activity from January still left it less than the activity in December, the total number of sunspots is still far above the number predicted by NOAA’s panel of solar scientists in 2020, with the rise towards a solar maximum also much steeper and far faster than predicted.

Romania signs Artemis Accords

9:08 am

Romania on March 1st became the sixteenth nation to sign the Artemis Accords, designed to get around the Outer Space Treaty’s restrictions on private enterprise and property rights in space.

Romania is now the third former Soviet block nation to sign the accords, joining Poland and the Ukraine. The full list of signatories now includes Australia, Brazil, Canada, Israel, Italy, Japan, Luxembourg, Mexico, New Zealand, Poland, Romania, South Korea, the United Kingdom, the United Arab Emirates, the Ukraine, and the United States.

Up to now Germany and France — two of the west’s most important major space powers — have resisted signing, probably because both countries have had strong partnership ties with Russia, and Russia opposes the accords. The Russian invasion of the Ukraine however has caused Germany to break off all such Russian cooperation, which suggests it now may be more amendable to signing. I also suspect France may become more willing, though predicting France in these matters is always difficult.
