NASA sets target launch date for SLS in February ’22

2:51 pm

As expected, the first unmanned demo launch of NASA’s SLS rocket has now been scheduled for a February launch window.

The first launch window for NASA’s Artemis I mission opens on February 12 at 5:56 p.m. EDT – yes, we have dates and times for this long-awaited mission. The February window lasts two weeks, with the first half of that window allowing a six-week mission and a four-week mission on the back half.

If for some reason NASA cannot launch in that firs window, they have back up windows in March and April. These windows exist because the plan is to send the Orion capsule to orbit the Moon from four to six weeks, and then return to Earth.

The announcement came the day after NASA had finally stacked the Orion capsule on top of the SLS rocket, essentially completing the rocket’s assembly.

Next Ariane 5 launch postponed

11:39 am

Arianespace today announced that it has postponed its next Ariane 5 launch of two communications satellites, scheduled for October 22nd, because of issues with ground equipment.

Though there appear to be no issues with the rocket, this delay could effect the launch of the James Webb Space Telescope in December on another Ariane 5 rocket. Arianespace has said that it wants to complete this launch first, to make sure the fixes it completed on the rocket’s fairing are truly working.

It was those problems that shut down all Ariane 5 launches for almost a full year.

No new launch date has been set. Normally, ground equipment issues cause short delays, so we should be hopeful all will be fixed quickly and this launch will be quickly rescheduled and take off without problems.

Cool image time! The photo above was cropped and enhanced by citizen scientist Gerald Eichstädt from a raw Juno image taken during that spacecraft’s 37th orbit. I have reduced it slightly to post here.

The photo shows what he calls “pop-up” clouds floating above a much larger cloud eddy. Unfortunately, Eichstädt provides no scale, but I suspect this image would easily cover the Earth, with those white clouds probably far larger than the biggest hurricane on Earth.

Ukraine and Nova Scotia to partner in spaceport deal

8:59 am

The new colonial movement: The Ukraine has agreed to be a partner in the building of a new spaceport in Nova Scotia.

It appears a Canadian company, Maritime Launch Services (MLS) has raised $10.5 million in investment capital to develop both the spaceport and a rocket it dubs Cyclone-4M. That company has also been negotiating with the Ukraine to buy engines from its two rocket engine manufacturers, Yuzhnoye and Yuzhmash, for that rocket. As part of the negotiations, the Ukrainian government has agreed to provide funding to these two companies.

Both sides will hold further meetings in Canada on this partnership in November, including top Ukrainian government officials, Deputy Prime Minister Oleg Uruskyi, State Space Agency of Ukraine Administrator Vladimir Taftai, and Foreign Affairs Minister Dmytro Kuleba.

China resumes communications with Tianwen-1 Mars orbiter

8:45 am

With the Sun no longer between the Earth and Mars, China has re-established communications with its Tianwen-1 Mars orbiter.

According to the CNSA [China National Space Administration], the orbiter will enter the remote-sensing orbit of Mars in early November to carry out global detection and obtain scientific data such as morphology and geological structure, surface material composition and soil type distribution, atmospheric ionosphere, and space environment of Mars.

The orbiter will also relay the communication between the rover and Earth for the rover’s extended mission, the CNSA added.

Based on this information, full communications with the rover Zhurong will not resume until November because the orbiter needs to re-adjust its orbit.

Nanoracks and Lockheed Martin to partner in building commercial space station

10:07 pm

Capitalism in space: The companies Nanoracks and Lockheed Martin have announced that they have formed a partnership to build their own private commercial space station, dubbed Starlab.

Nanoracks, its majority owner Voyager Space and Lockheed Martin, will collaborate on the development of a commercial space station as others in industry warn of a potential space station gap.

Nanoracks said Oct. 21 that it was partnering with Lockheed Martin and Voyager Space on a commercial space station called Starlab. Nanoracks will be the prime contractor with Voyager handling strategy and investment and Lockheed serving as the manufacturer and technical integrator.

Starlab would consist of a docking node with an inflatable module attached to one side and a spacecraft bus, providing power and propulsion, attached to the other side. Starlab will have a volume of 340 cubic meters, about three-eighths that of the International Space Station, and generate 60 kilowatts of power. Starlab will be equipped with a robotic arm and “state-of-the-art” lab, and be able to host four astronauts at a time.

They are aiming for a 2027 launch.

Curiosity’s new mountain views

1:14 pm

Curiosity's future route
Click for full image.

With the resumption of communications with Mars, following the two week hiatus because the Sun was in the way, Curiosity is about to begin its travels again. The view above, taken by the right navigation camera and reduced and annotated to post here, looks forward, with the red dotted line indicating the planned route.

The distinct white outcrop on the right top is the same spectacular outcrop I have highlighted previously.

At the moment however the rover is not going anywhere. Just before the hiatus the scientists had Curiosity move a short distance to crush some nearby nodules so that they could see their interior. At their update they post an image of one crushed nodule, and write the following:

[L]ook closely for very straight imprinted lines in the middle of flattened areas that appear slightly more grey. You can also see cracks, especially clearly on the right of the nodule in the image, but if you look around, you’ll find there are more of them. Some of the scratched areas are looking white, too. All those features will allow us an insight into the nodules and an interpretation beyond what we can otherwise see on the surface.

The image below, also taken by the right navigation camera and reduced to post here, looks back at Curiosity’s earlier travels, across the floor of Gale Crater about 1,500 feet below. The rim, about 25 miles away, can be seen through the atmospheric haze as the distant mountain chain.

See the orbital map at this post in September to get the context of what the two images are viewing. The top image looks south along the cliff line, the bottom looks almost due north.

A collapsing north wall in Valles Marineris

Mass wasting in Valles Marineris
Click for full image.

Cool image time! The photo to the right, rotated, cropped, and reduced to post here, was taken on July 17, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the scientists label as an alluvial fan.

I have also seen them label this kind of avalanche as mass wasting, where the material moves down slope suddenly in a single mass.

The image shows the aftermath of such an event, after a large blob of material broke free from the mountainside and slid almost as a unit downhill to settle more than two miles away on the floor of the canyon. The distance traveled and the blobby nature of the flow both reveal how the lower Martian gravity changes the nature of such events, compared to what you might see on Earth. The flows can travel farther, and can hold together as a unit easier.

The overview map below not only provides the context, but it tells us that such events are remarkably common in this place.

Russian filmmakers describe their experience of filming a movie in space

9:06 am

Capitalism in space: The Russian actress Yulia Peresild and her director Klim Shipenko — who spent twelve days on ISS filming scenes for a science fiction movie — gave a press conference yesterday, describing their experience and what they accomplished.

They shot more than 30 hours worth of footage which will later be edited down to about 30 minutes. “We’ve shot everything we planned,” Shipenko said from the Yuri Gagarin Cosmonaut Training Center outside Moscow.

The 38-year-old US-educated film director said cinema was ready to conquer space. “Cinema is looking for new forms. The cosmos is also ready to welcome various experimentalists,” said Shipenko.

He said his stint on the ISS was full of professional discoveries and added that he would never have been able to shoot on Earth what he had shot in space.

Both regretted that their work scheduled on ISS was so busy that they did not have enough time to look at the views out the station’s windows.

When this movie is finished I wonder if it will get a distribution deal in the west. I certainly would like to see it, and I am certain many other Americans will feel the same.

Rocket Lab to attempt another recovery of 1st stage on next launch

8:57 am

Capitalism in space: In its next launch in mid-November, Rocket Lab will attempt another recovery of the first stage of its Electron rocket.

Rocket Lab USA, Inc (“Rocket Lab” or the “Company”) (Nasdaq: RKLB) has today revealed it will attempt a controlled ocean splashdown and recovery of the first stage of an Electron rocket during the company’s next launch in November. The mission will be Rocket Lab’s third ocean recovery of an Electron stage; however, it will be the first time a helicopter will be stationed in the recovery zone around 200 nautical miles offshore to track and visually observe a descending stage in preparation for future aerial capture attempts. The helicopter will not attempt a mid-air capture for this mission but will test communications and tracking to refine the concept of operations (CONOPS) for future Electron aerial capture.

The eventual goal is for the helicopter to snatch the stage by its parachutes as it descends, and then bring it back to deposit it gently on land. This next launch will likely provide the company the data it needs to make that maneuver more safely and with a greater chance of success on a future launch.

The November splashdown recovery will follow two previous successful such recoveries. In addition, the company has also done a test whereby one helicopter dropped a dummy first stage, its parachutes opened, and a second helicopter successfully grabbed it. With the addition of the helicopter on this launch it will likely be poised to attempt a full recovery out of the air.

Israel & UAE sign deal to work together on space projects

8:45 am

The new colonial movement: This week Israel and the United Arab Emirates (UAE) signed an agreement calling for them to work together on a variety of space projects.

Israel and the United Arab Emirates signed a historic deal regarding space missions, Ynet reported on Tuesday, which will include collaborating on the Israeli rocket ship “Beresheet 2” space project bound for the Moon.

As part of the agreement, the two nations will work together on data-based development and research from the Israeli-French satellite Venus, while students from the UAE will work with Israeli students on a new satellite tracking the Moon.

The lack of general excitement over this agreement is truly astonishing. Remember, just a few years ago no Arab nation could dare reveal any partnership or even direct communication with Israel, out of fear of the violent reaction throughout the Islamic world. Now, the UAE can sign a deal where its citizens will work side-by-side with Israelis on several different projects, and the world barely notices.

More than anything, this disinterest signals the importance of the Abraham Accords engineered by the Trump administration. Those agreements, disavowed by the Biden administration, made this partnership possible.

Senate committee: NASA must choose two companies to build manned lunar lander

5:09 pm

We’re here to help you! Despite offering NASA only $100 million more for the program, the Senate Appropriations committee has directed the agency to award a second manned lunar lander contract, in addition to the one it gave SpaceX in April.

On Tuesday (Oct. 18), the Senate Appropriations Committee — the largest U.S. Senate committee that oversees all discretionary spending legislation in the Senate — released a draft report of nine appropriations bills for the fiscal year 2022 which included funding for NASA, according to SpaceNews.

The appropriators, in the report, state that NASA’s HLS program is not underfunded, despite the agency’s previous claims to the contrary. As shown in the report, the bill includes $24.83 billion for NASA, which is just slightly more than the $24.8 billion that NASA requested, and a $100 million increase in funding for HLS.

“NASA’s rhetoric of blaming Congress and this Committee for the lack of resources needed to support two HLS teams rings hollow,” the report states. The committee added that “having at least two teams providing services using the Gateway should be the end goal of the current development program,” referencing NASA’s Gateway, a planned lunar space station.

It might be possible for the increase in funding to cover a second contract, if that contract was awarded to Blue Origin. Jeff Bezos has made it clear that he would be willing to waive as much as $2 billion of the price for the contract, using his own ample funds to make up the difference. Whether that is enough to build it, with the $100 million the Senate appropriated, is unclear.

This bill of course has to pass the Senate, be approved as written by the House, and then signed by the President. These directives and budget changes thus might not end up in the final appropriations bill.

Boeing to take Starliner apart, remove two valves

4:57 pm

Boeing has decided to take apart the Starliner capsule intended for its second unmanned demo flight to ISS to do a close inspection of two of the troublesome valves that caused the launch in August to be scrubbed.

The current guess at what caused the valve issue involves moisture that accumulated near some of the valves’ Teflon seal. But without any clear culprit, the company now plans to ship two of the valves to a NASA center in Huntsville, Ala., for a forensic CT scan, using machines similar the ones used on humans to detect diseases.

This action now means that the next launch attempt will likely be delayed until the middle of ’22.

The delay is costing Boeing money, not NASA, as the contract is fixed price and Boeing will not get paid additional money until it meets its next milestone, which is a successful demo flight to ISS.

Did China test a hypersonic weapon in August?

10:14 am

Long March 2C rocket
China’s Long March 2C rocket

On October 17th The Financial Times published a story claiming, based on anonymous sources, that one of China’s five launches in August tested a hypersonic weapon, which supposedly circled the globe to impact the Earth only 24 miles from its target.

The Financial Times story is behind a paywall, but not surprisingly it was picked up by much of the mainstream press, with the conservative press — as illustrated by this Daily Wire story — accepting the weapon as fact, while the leftist press — as illustrated by this CNN story — giving China the opportunity to deny the claim.

Did it actually happen? I have no idea. I would add however that I would not trust any story dependent wholly on anonymous sources, considering the unreliability of today’s press and the repeated evidence that numerous federal agencies in the military and intelligence communities routinely feed it disinformation for their own political purposes. These agencies, including the Space Force, want to encourage Congress to fund them, and creating a bogey man threat that the press can tout has for decades been the standard way to do it.

To get a better idea whether this hypersonic flight happened, let’s review the actual Chinese launches in August to see if any might be a likely candidate. For a launch to fit the description, there would have to be almost no information about its payload, and that payload would have to have not reached orbit, since the hypersonic test circled the globe once and then impacted the Earth.

Scientists resume communications with U.S. Martian rovers

9:11 am

Example of first rover images downloaded following communications break
Click for full image.

Both U.S. Mars rovers Curiosity and Perseverance have resumed communications with Earth, each downloading a bunch of images that they had been programmed to take during the two week communications hiatus from October 3 to October 17, caused by the Sun being between the Earth and Mars.

Most of the images are a variation of the one to the right, reduced to post here, taken by Curiosity’s left hazard avoidance camera. As neither rover moved during the communications break, the scientists limited most photography to only a handful of cameras, with the photographs mostly confirming day to day that the rover and its instruments were functioning.

You can see all of Curiosity’s new images here. Perseverance’s new images can be viewed here. (To see the new Perseverance images click on “latest images.”)

A Curiosity team update today notes the work they plan to do in the coming days as they gear up for future travels. The Perseverance update today focused more on the paper published during the break that confirmed, using data from the rover, that Jezero Crater once contained a lake.

First FAA hearing on Starship environmental assessment dominated by supporters

8:48 am

Capitalism in space: The FAA yesterday conducted its first of two virtual public hearings to allow public comment on its proposed environmental assessment that would allow SpaceX to launch orbital Starship missions from Boca Chica, Texas>

According to the story at the link, the comments were dominated by supporters, interspersed with the typical small number of anti-development environmental activists.

Over the course of more than three hours on Monday, members of the public who had registered in advance were given three minutes each to deliver their oral public comments on Starship and the draft. Most were in favor of SpaceX, though many positive comments appeared to originate from outside of Texas. A smaller number of people also voiced concerns about impacts on local ecosystems and species near Boca Chica.

The second hearing is scheduled for tomorrow.

Parker probe completes fifth Venus flyby

8:40 am

The Parker Solar Probe on October 16th successfully completed its fifth flyby of Venus, designed to lower its solar orbit around the Sun.

At just after 5:30 a.m. EDT, moving about 15 miles (24 kilometers) per second, the spacecraft swooped 2,370 miles (3,814 kilometers) above Venus’ surface. Such gravity assists are essential to the mission to bring Parker Solar Probe progressively closer to the Sun; the spacecraft counts on the planet to reduce its orbital energy, which in turn allows it to travel closer to the Sun and measure the properties of the solar wind near its source.

This was the fifth of seven planned Venus gravity assists. The flyby reduced Parker Solar Probe’s orbital speed by about 6,040 miles per hour (9,720 kilometers per hour), and set it up for its 10th close pass (or perihelion) by the Sun, on Nov. 21.

Parker Solar Probe will break its own distance and speed records on that closest approach, when it comes approximately 5.3 million miles (8.5 million kilometers) from the Sun’s surface — some 1.2 million miles (1.9 million kilometers) closer than the previous perihelion on Aug. 13 – while reaching 101 miles (163 kilometers) per second, or 364,621 miles per hour. Assisted by two more Venus flybys, in August 2023 and November 2024, Parker Solar Probe will eventually come within 4 million miles (6.2 million kilometers) of the solar surface in December 2024.

That speed record, 364,621 miles per hour, is the fastest any human built object as ever traveled.

Update on Lucy: panels generating more than 90% of expected power

9:38 pm

According the Lucy science team, the spacecraft’s solar panels are generating more than 90% of the expected power at this stage of the mission, despite the fact that one panel did not deploy completely and has not latched in final position.

“We’re very happy to report that we are getting most of the power we expected at this point in the mission,” said Joan Salute, associate director for flight programs at NASA’s planetary science division. “It’s not 100%, but it is fairly close. So that is great news.’

In an interview with Spaceflight Now, Salute said the power output from the solar arrays appears to be “most likely above 90%” of the expected level of 18,000 watts. “We don’t know if it’s a latch problem, or that it is only partially deployed,” Salute said.

If correct, there is an excellent chance the mission will not be seriously hindered, even if they cannot get the panel fully deployed or latched. At the same time, there are worries about firing Lucy’s main engine for major course corrections with the panel unlatched. The first major course correction is scheduled for mid-November.

The engineers are presently reviewing their data. One option might be to order the spacecraft to re-attempt a full deployment, in the hope that the process will complete during that second attempt.

The icy Phlegra Mountains on Mars

1:37 pm

Overview map

Cool image time! The Phlegra Mountains on Mars are probably the iciest mountains on the red planet, something I noted previously in an April 2020 essay, highlighting a half dozen images from the high resolution camera on Mars Reconnaissance Orbiter (MRO) that showed that iciness. As I stated:

Here practically every photograph taken by any orbiter appears to show immense glacial flows of some kind, with some glaciers coming down canyons and hollows [#1], some filling craters [#2], some forming wide aprons [#3] at the base of mountains and even at the mountains’ highest peaks [#4], and some filling the flats [#5] beyond the mountain foothills.

And then there are the images that show almost all these types of glaciers, plus others [#6].

The overview map above not only shows the locations of these six images in black, it also shows in red two of SpaceX’s four prime candidate landing sites for its Starship spacecraft. Note that #3 above is one of those sites.

The white rectangle in the Phlegra Mountains marks the location of today’s cool image below, taken on June 11, 2021 by MRO’S high resolution camera.

Rocket Lab reschedules next launches

9:41 am

Capitalism in space: Rocket Lab has now announced that it has delayed its next two launches from mid-October to mid-November.

A two-week window is planned for the first launch — from Nov. 11 to Nov. 24 —when its Electron rocket will deploy two satellites into low-Earth orbit. The company aims to deploy two more satellites in the second launch for the mission after Nov. 27.

Both launches are scheduled to take place at the Rocket Lab Launch Complex 1 on New Zealand’s Māhia Peninsula.

The announcement does not provide an explanation for this delay. However, Rocket Lab had originally scheduled these launches for August/September, but lockdown restrictions in New Zealand due to its panic over COVID-19 had forced it to trim its launches there by half for the rest of the year. Rather than do five as planned, the company is only going to do two, and it appears those two are the launches now set for November.

China gets failed satellite to proper orbit

9:19 am

A Chinese satellite launched in late September that failed to reach its designated orbit after deployment has now reached that correct orbit.

During the launch of the Chinasat 9A mission in June 2017, the Reaction Control System (RCS) of the rocket stopped working during the coast phase, which resulted in a sub-planned payload release. The satellite, however, used its onboard propulsion to reach the desired orbit even with the rocket underperforming.

In September the limited information released by China suggested the launch had been a success but the satellite failed after deployment. Based on this new information, the launch in September only became a success now, as the failure was in the rocket’s upper stage.

China has not revealed the purpose of this satellite, though it is part of a program known to launch satellites for testing cutting edge technology.

NASA document: Starship orbital flight in March ’22

9:11 am

Starship orbital flight date?
Click for full image.

According to a NASA proposal to observe and measure the temperatures on Starship’s thermal protection during its return to Earth from orbit, that flight is now tentatively scheduled for March ’22.

The graphic to the right highlights the pertinent language in the poster presentation.

It must be noted that the poster might not be telling us when Starship will first launch, but when the designers of the camera system will be ready to film. The two are different. Still, the slowdown in flight testing at Boca Chica by SpaceX since July suggests there may be some truth to this date. That date also seems more reasonable now in connection with the FAA’s regulatory pace, which still needs to provide the final approval of SpaceX’s environmental reassessment of its Boca Chica launch site.

It also seems to me that the March ’22 date would be very convenient for NASA, as it almost certainly guarantees that Starship will reach orbit after SLS, thus avoiding for the agency a very big public relations embarrassment. I would not be surprised at all if the Biden administration and NASA’s top administrators, led by Bill Nelson, are purposely pressuring the FAA to make sure that Starship orbital flight is delayed until after the first SLS test flight, now expected in the January/February time frame.

There is also the possibility that SpaceX’s targeted launch dates were unrealistically optimistic. The company had a lot of work it needed to do prior to launch on its orbital launch facility at Boca Chica, and that work could not go forward while test flights and static fire tests were taking place. Pausing those tests has allowed the launch facility work to move forward aggressively.

A Lucy solar panel on Lucy fails to latch properly after deployment

8:40 am

Partly deployed panel

Engineers at Lockheed Martin (the prime contractor) and Northrop Grumann (which built the panels) are now troubleshooting an issue with one of the solar panels on the asteroid probe Lucy, which failed to latch properly after deployment.

The NASA graphic to the right illustrates this issue, though the graphic might not accurately portray the exact circumstance at Lucy. To get more solar power, Lucy’s panels are larger, and thus were designed to unfurl like a fan rather than the more commonly used accordion design. One panel has not completed that unfurling.

NASA’s announcement tries to minimize the issue but this quote from the link makes it clear that this could be a very big problem.

It’s not yet clear whether the array in question is, in fact, fully deployed but not latched in place or whether it did not reach full deployment and is not generating the same amount of power as its counterpart. It’s also not yet clear whether Lucy can safely fire its maneuvering thrusters with an unlatched array.

Monaco’s government establishes “Bureau of Space Affairs”

9:27 am

Capitalism in space: Monaco’s government announced this week that it has created a Bureau of Space Affairs, aimed at encouraging commercial space operations within the country.

By setting up a ‘one-stop-shop’ for aerospace-related matters, and reporting to the Digital Platforms and Resources Department (under the authority of the Minister of State), the Principality is taking its first steps towards supporting the growth and development of these companies by streamlining administrative procedures, and will also act as the welcome office for any prospective aerospace-related businesses looking to set up in Monaco.

At the international level, the Office of Space Affairs will represent the Princely Government in the relevant international organizations, in co-operation with the Department of External Relations and Cooperation. The Office of Space Affairs will interact with its counterparts in other countries for knowledge sharing, to foster economic cooperation, and to benefit Monegasque companies in aerospace and related fields.

Such government agencies are popping up in third world countries worldwide, with almost all having goals focused on helping and encouraging the booming private commercial marketplace and attracting it to their countries. This is great news.

That these countries are also competing worldwide for this business is also great news. It will discourage them from trying to take control, as government agencies are wont to do and as NASA did in the U.S. in the 1970s. Instead, the competition will force them all to keep their bureaucracies as streamlined as possible, so as to attract as many businesses as possible.

Russian filmmakers safely return to Earth

11:59 pm

Capitalism in space: A Russian Soyuz capsule safely returned three Russian astronauts to Earth today, including the two filmmakers that spent the last twelve days filming scenes on ISS for a movie.

Russian actress Yulia Peresild and producer Klim Shipenko landed with cosmonaut Oleg Novitskiy of the Russian federal space corporation Roscosmos on Sunday (Oct. 17). The three descended aboard the Soyuz MS-18 spacecraft to a touchdown at 12:35 a.m. EDT (0435 GMT or 10:35 a.m. local time) on the steppe of Kazakhstan.

The landing concluded 191 days in space for Novitskiy, who wrapped up his stay on the station by playing a bit part in the movie Peresild and Shipenko were there to film. A joint production of Roscosmos, the Russian television station Channel One and the studio Yellow, Black and White, “Вызов” (“Challenge” in English) follows the story of a surgeon (Peresild) who is launched to the station to perform emergency surgery on a cosmonaut (Novitskiy).

ULA’a Atlas-5 successfully launches the Lucy asteroid probe

6:08 pm

ULA’a Atlas-5 rocket early this morning successfully launched the Lucy asteroid probe on a 12 year mission to study eight Trojan asteroids over a period from 2025 to 2031. One tidbit about the mission is especially creative:

Scientists named the Lucy mission after the fossilized remains of a human ancestor, called Lucy by the scientists who discovered her in Ethiopia in 1974.

The leaders in the 2021 launch race:

36 China
23 SpaceX
17 Russia
4 Northrop Grumman
4 ULA

The U.S. and China are once again tied in the national rankings, at 36 each.

Thrusters on Soyuz docked to ISS fire improperly

10:00 pm

The thrusters on the Soyuz capsule to be used to return the two filmmakers and one Russian astronaut back to Earth on October 17th would not stop firing when they were supposed to during routine testing in preparation for undocking.

From the NASA announcement, which by the way buried this event in the announcement’s eighth paragraph:

At 5:02 a.m. EDT today, Russian flight controllers conducted a scheduled thruster firing test on the Soyuz MS-18 spacecraft that is scheduled to return to Earth Saturday night with three crew members aboard. The thruster firing unexpectedly continued after the end of the test window, resulting in a loss of attitude control for the International Space Station at 5:13 a.m. Within 30 minutes, flight controllers regained attitude control of the space station, which is now in a stable configuration. The crew was awake at the time of the event and was not in any danger.

Flight controllers are continuing to evaluate data on the station’s brief attitude change due to the thruster firing. NASA and Roscosmos are collaborating to understand the root cause.

According to the first link, the thrusters tilted the entire station 57 degrees from its correct orientation.

Not only do they not know why the thrusters did not shut down when commanded, they do not know why they eventually stopped firing. They suspect it was because the thrusters ran out of fuel, but this is not yet confirmed.

The Russians still plan to use this Soyuz to return the film crew in two days. The story does not say whether these thrusters are needed in any way to deorbit the capsule.

That’s the second uncontrolled thruster firing from a Russian spacecraft docked to ISS in less than three months. Yet, no such thing had occurred for many decades prior to this. In fact, the last such events that I can remember occurred in the 1960s.

Why such events are suddenly occurring now with such frequency is very concerning, to put it mildly. It brings to my mind the drilled hole in an earlier Soyuz capsule, a hole that was clearly drilled in Russia when the capsule was on the ground and then covered up so it was not detected until the capsule was docked to ISS. The Russians investigated, said they solved the mystery, but have never told anyone what that solution was.

To paraphrase Shakespeare, something is very rotten in Roscosmos.

Dry Martian chaos

1:52 pm

Dry chaos on Mars
Click for full image.

On Mars, one of the most common kinds of landscape is called chaos terrain. Made up of mesas, buttes, and cross-cutting random canyons, this geology is not seen on Earth, and when first identified by scientists in early orbital pictures in the 1970s, it baffled them. While it is clear that some form of erosion process caused it, the scientists did not have enough data then to figure out what that process was.

Today scientists have a rough theory, based on what they now know about Mars’ overall geology and its climate and orbital history. The canyons of chaos terrain were originally fault lines where either water or ice could seep through and widen. See this January 2020 post for a more detailed explanation.

Most of the cool images I have posted of chaos terrain have been in places in the mid-latitudes that are covered with glaciers. See for example this December 2019 post of one particular mesa in glacier country, with numerous glaciers flowing down its slopes on all sides. That mesa is quite typical of all such mesas in the mid-latitudes.

Today’s cool image above, cropped to post here, takes us instead to the Martian very dry equatorial regions. The photo was taken on May 17, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), and like mid-latitude chaos, it shows a collection of random mesas with canyons cut almost randomly between.

Unlike the mid-latitudes, however, there is no evidence of glaciers here. Instead, the canyons and mesa slopes are covered with dust, shaped into wind-blown dunes.

As always, the overview map below gives us some context.

China successfully launches three astronauts to its space station

9:36 am

Launch of Shenzhou

The new colonial movement: China today successfully used its Long March 2F rocket to place three astronauts into orbit to begin a six month mission to that country’s new space station.

The image to the right is a screen capture from the live stream, mere seconds after launch.

It appeared to me that the rocket’s first stage might have had grid fins to control its reentry, but I am not certain. Either way both it and the four strap-on boosters will crash in China.

The Shenzhou capsule will dock with the station in a few hours.

The leaders in the 2021 launch race:

36 China
23 SpaceX
17 Russia
4 Northrop Grumman

China has now moved ahead of the U.S. in the national rankings, 36 to 35.
