Russia launches military satellite

8:37 am

Russia early this morning successfully launched a classified military satellite, its Soyuz-2 rocket lifting off from its Plesetsk spaceport in northern Russia.

No word on where the rocket’s strap-on boosters or first stage crashed within Russia.

The leaders in the 2023 launch race:

92 SpaceX
61 China
18 Russia

December 13, 2023 Quick space links – All Russia today

3:32 pm

  • Russia planning to lay off several major managers in manned program

    • The article at the link states that this decision suggests Roscosmos is shifting from space exploration and science to doing military and commercial missions. Sadly, these former communists still don’t understand how freedom works, which if allowed to flourish will end up paying for both.

 

  • Russia’s proposed space station is shrinking

    • This story is related to the first above. Rather than having the new station made up of several modules, like ISS, Tiangong-3, and Mir, Roscosmos’ division that builds its manned spacecraft, Energia, is working out a one-module design comparable to the Soviet Union’s Salyut stations from the 1970s.

In other words, the news from Russia today is that it is recognizing it no longer has the capability to build a manned space program. The decision to invade the Ukraine, and the resulting isolation and loss of its international satellite business, has left Roscosmos very short of cash.

Russia & China appear to time their secret space operations to American holidays

9:13 am

According to data gathered by the startup LeoLabs, which attempts to track objects in orbit, both Russia and China appear to time their secret space operations to American holidays, likely in the hope fewer eyes are watching at that moment.

The latest evidence happened on Nov. 23, US Thanksgiving, when Russia’s Cosmos 2570 satellite in low Earth orbit (LEO) revealed itself to be a Matryoshka (nesting) doll system — comprising three consecutively smaller birds, performing up-close operations around each other, according to the company. This “spawning” event mimicked the activity of Cosmos 2565, launched on Nov. 30, 2022 and believed to be an electronic reconnaissance satellite, which released a daughter satellite (Cosmos 2566) on Dec. 2, and which, in turn, released its own baby satellite on Dec. 24 (Christmas Eve), according to LeoLabs.

Similarly, on the 25 and 26 of November 2022, LeoLabs said it observed China’s spaceplane, which Beijing calls Test Spacecraft 2, “conduct[ing] rendezvous and proximity operations” that involved a docking maneuver by a satellite it released, Victoria Heath, LeoLabs team lead for communications and marketing, told Breaking Defense. A second docking “likely took place” around Jan. 10, 2023, she said.

In the end it appears this effort only delays observations, at best, but that does give these countries a slight window to do some tests unobserved.

Russia launches Progress to ISS

9:09 am

Russia early this morning successfully launched a Progress freighter to ISS, its Soyuz-2 rocket lifting off from Baikonur in Kazakhstan.

The rocket’s core stage, strap-on boosters, and second stage crashed in the standard drop zones the Russians have used since the launch of Sputnik in 1957. It is unclear how close to inhabited areas any of these are.

The leaders in the 2023 launch race:

87 SpaceX
53 China
16 Russia
7 Rocket Lab
7 India

American private enterprise still leads China in successful launches, 99 to 53, and the entire world combined 99 to 85. SpaceX by itself still leads the entire world (excluding other American companies) 87 to 85.

SpaceX however has two launches scheduled for today, one at Vandenberg at 10:04 am (Pacific) and the second at Cape Canaveral at 11 pm (Eastern). The links go to the live streams.

Russia launches military satellite

7:59 pm

Russia today successfully placed a classifed military satellite in orbit, its Soyuz-2 rocket lifting off from its Plesetsk spaceport in northern Russia.

The satellite is likely a reconnaissance satellite. No word on where the rocket’s core stage and strap-on boosters landed inside Russia, though launches from Plesetsk generally head north over very empty regions and the Arctic, and as the satellite appears to have an orbit with an inclination of 67 degrees that is likely in this case.

The leaders in the 2023 launch race:

86 SpaceX
53 China
15 Russia
7 Rocket Lab
7 India

American private enterprise still leads China 98 to 53 in successful launches, and the entire world combined 98 to 84. SpaceX meanwhile maintains its lead over the rest of the world (excluding American companies) 86 to 84.

Two Russian satellites — one thought defunct — have been tracked in rendezvous maneuvers

8:51 am

The American commercial satellite tracking company has over the past two years identified two Russian satellites — one thought defunct — that have rendezvoused and done proximity maneuvers.

Resurs-P3 — a Russian Earth observation satellite — performed a large maneuver in November 2022 after years of inactivity, and approached the Russian military satellite Cosmos-2562, according to a LeoLabs briefing.

The maneuver by Resurs-P3 “placed it in an entirely new orbit shared by Russian assets with non-publicly disclosed payloads,” said the briefing. “Based on the approaches observed by LeoLabs, it’s highly likely that Cosmos-2562 has an electro-optical payload and has collected high-resolution imagery of Resurs-P3.”

This new data further documents the long-term classified Russian effort to develop such satellite maneuvering capability, both to track and inspect its own satellites as well as do the same to the satellites of others. The unstated capability also includes the ability to destroy a satellite also, once rendezvous is achieved.

Russia’s Soyuz-2 rocket launches military satellite

9:40 am

Russia today used its Soyuz-2 rocket to launch a classified military surveillance satellite, lifting off from its Plesetsk spacesport in northern Russia.

A graphic at the link shows the rocket’s flight path crossed over almost all of Russia as it flew east, with its lower stages and fairings crashing on land. Though the drop zones were inside Russia, there are very isolated regions in the high Arctic latitudes, with few inhabited areas.

The leaders in the 2023 launch race:

76 SpaceX
48 China
14 Russia

Russian astronauts locate coolant leak on spacewalk

9:29 am

Coolant leak on Nauka radiator

In an almost eight hour spacewalk yesterday, two Russian astronauts were able to locate the source of the coolant leak on a radiator unit connected to the new Nauka module on the Russian half of ISS.

The image to the right, a screen capture from the live stream, shows the leak location, where a small white droplet sits on one of the coolant lines that connect two radiator panels. You can also see darkening on the tubes to either side, likely also caused by the leaking ammonia. To locate it ground controllers opened valves to let coolant into the line while the astronauts watched for changes, and were able to see the coolant come out of this spot.

One astronaut also noted the following during the inspection:

[B]efore noticing the growing deposit of liquid coolant, Kononenko reported seeing a myriad of small holes on the surface of the radiator’s panels. “The holes have very even edges, like they’ve been drilled through,” Kononenko radioed to the flight controllers working in Moscow Mission Control. “There are lots of them. They are spread in a chaotic manner.”

In the past year similar coolant leaks have occurred on both a Progress freighter and a Soyuz manned capsule, with the leak location in almost the exact same spot, suggesting an intentional cause, not a random micrometeorite hit. This coolant leak in Nauka is on equipment that was launched to ISS in 2010. If it was also drilled, whoever did it did so a long time ago, which implies Russia has a long standing saboteur within its operations.

This conclusion however remains wild speculation. In the dozen-plus years since launch, this radiator has been stored on the outside of ISS, where it could easily have been hit by micrometeorites that would cause those holes and this leak.

The plan is to consider some repair operation on future spacewalks. In the 1980s the Russians did something similar, with astronauts doing six spacewalks to replace a section of fuel line that was leaking on its Salyut-7 station. They cut open its hull and installed a second section of line so that the valves could remove leaking section from operations.

Russia announces revised schedule for its lunar unmanned projects

9:04 am

NPO Lavochkin, the Roscosmos division that builds Russia’s lunar landers, has now announced a revised schedule for all of that country’s proposed lunar unmanned projects, following the failure of its Luna-25 lander in August.

The program calls for at least six missions, including orbiters, landers, and a rover, launching from 2027 through the 2030s. However, this quote from the article is the reality:

As often before, the latest strategy relied on the development time frames that had never been demonstrated by NPO Lavochkin in comparable projects in the past three decades.

What is worse is the 100% failure record of Lavochkin’s planetary probes once launched. It takes forever to build anything, and then what it builds and launches doesn’t work.

Not that this absimal record will cost Lavochkin anything. The Russian government and the bureaucracy that controls it does not allow any competition. Instead, like prohibition-era mobsters, divisions like Lavochkin carve up territories that they control, and allow no one else in. For example, Lavochkin owns planetary research while Energia, another division in Roscosmos, controls manned space flight as well as its launch industry. No one else is allowed it enter these markets, which means Lavochkin can fail repeatedly for the next century and nothing will change.

Russian geosynchronous spy satellite making close-up inspections of other commercial satellites

9:13 am

A second Russian “inspector” spy satellite in geosynchronous orbit is being directed to move relatively close to other commercial satellites, close enough to obtain high resolution images.

According to data gathered by California startup Slingshot Aerospace, the satellite known as Luch-5X or Olymp-K-2 [Norad ID 5584] began moving east to west shortly after its launch on March 12 — in what company officials told Breaking Defense on Oct. 6 shows a “pattern of life” that includes making stops nearby non-Russian satellites.

So far it the closest it has gotten to another satellite is about 10 miles, just far enough away so as to avoid triggering any collision concerns but close enough that good cameras will see fine details. It is believed the satellite so far under surveillance is a communications satellite from Eutelsat that covers Europe, Africa, the Middle East, and central Asia, suggesting a link to the wars in the Ukraine and Gaza.

ISS Russians to do spacewalk on October 25 to investigate Nauka coolant leak

8:38 am

Due to the coolant leak that appeared in a back up outside radiator connected to Russia’s Nauka module, NASA and Russia have rearranged their upcoming spacewalk schedule, with two American spacewalks now delayed until after a Russian spacewalk on October 25 that will investigate the leak.

During that spacewalk, [Oleg] Kononenko and [Nikolai] Chub will install a synthetic radar communications system on the Russian segment of the orbiting laboratory and deploy a nanosatellite to test solar sail technology. In addition, they plan to inspect and photograph the backup radiator that leaked on the Nauka multipurpose laboratory module.

The leak itself has stopped, though neither NASA nor Roscosmos have explained why. The leaked material is considered non-toxic, but there appears to be a concern it might get into some “internal systems” and cause problems.

NASA delays two ISS spacewalks as Russian engineers assess now stopped leak on Nauka module

8:54 am

NASA yesterday confirmed it is delaying by at least one week two ISS spacewalks in order to allow more time for Russian engineers to analyze the causes of the coolant leak on Nauka module and assess its short and long term consequences for the station.

The spacewalks were deferred from their original target dates to allow engineers additional time to complete their analysis of the coolant leak, which occurred on Oct. 9 and has now stopped. [emphasis mine]

The highlighted words are the most important takeaway. The leak has stopped leaking, though we have not been told why. The Russians might have closed off the leaking radiator from the system, or maybe the leak stopped on its own for unknown reasons. More information is clearly required.

South Korea is in final negotiations to cancel two Russian launch contracts

8:44 am

As has been expected since the beginning of Russia’s invasion of the Ukraine, South Korea is in the process of canceling two Russian launch contracts, with the negotiations apparently now in the final stages.

“The Korea Multipurpose Satellite 6 and the next-generation mid-size satellite Compact Advanced Satellite 500-2, both developed by Korea, were initially scheduled to be launched into space using Russian launch vehicles, but due to the war between Russia and Ukraine and the subsequent international sanctions against Russia, there were uncontrollable circumstances that prevented the use of Russian launch vehicles,” the Ministry of Science and ICT said in a statement.

“Since then, Korea has been negotiating with Russia on the terms of termination of the satellite launch contract and it is currently being finalized.”

South Korea has already found a different rocket for the first satellite, scheduled for launch on Arianespace’s Vega-C rocket when it resumes flights in April 2024 (after completing upgrades resulting from a December 2022 launch failure). As for the second satellite, no public decision has yet been announced, though contract bidding has been on-going.

Meanwhile South Korea is accelerating development of its own Nuri rocket, which it has successfully launched two times already.

Russia in turn no longer has any international customers for its rockets. Its invasion of the Ukraine has cost it hundreds of millions of dollars of lost business, all of which will likely not return for decades.

Three astronauts return to Earth safely, completing 371 day mission

9:13 am

One American, Frank Rubio, and two Russians, Sergey Prokopyev and Dmitri Petelin, early today safely returned to Earth in their Russian Soyuz capsule, completing the longest mission yet on ISS, 371 days, and the third longest human mission ever.

The mission was the longest by accident. It was originally supposed to be a standard six month tour, but was extended to a year when the Soyuz capsule they came in developed a leak in its coolant system and had to be replaced.

The previous record for an American in space of 355 days was set by Mark Vande Hei last year. This new year-long mission is only exceeded by two Russian missions on Mir, Valeri Polykov’s 439 day mission in 1994-1995, and Sergei Avdeyev’s 381 day mission in 1998-1999.

The emerging long term ramifications of the Ukraine War

2:09 pm

With the war in the Ukraine now in the second half of its second year, with no clear outcome on the horizon, I thought it might be a good time to step back and look at what Russia’s invasion has wrought, not just on Russia and the Ukraine, but on the rest of the world, now and possibly into the long term future.

My goal in this essay is to look at the forest, not the trees, and to do so in very broad strokes, based on my experience as a historian who has taken this approach in all my histories.

First however it is necessary to give a short update on the war itself. In my previous two updates in April and July I concluded that the war was devolving into a stalemate, much like the ugly trench warfare of World War I. Nothing has changed that conclusion in the two months since July, a fact that is starkly illustrated by the two maps below, originally created by the Institute for the Study of War (ISW) and modified and annotated by me to highlight the most significant take-aways.

Russian investigators pin down cause of Luna-25 failure

10:03 am

Though the investigation is not yet complete, reports out of Russia indicate that the cause of the failure of Luna-25 during an engine burn while in orbit around the Moon has been identified.

The article at the link provides the details, which involve problems with two “BIUS-L accelerometers” during the flight, which for reasons not yet understood were switching from the primary to the secondary randomly during the journey to the Moon, apparently because of some failure.

However, ahead of the fateful lunar orbit correction on August 19, both accelerometers worked correctly, but once the maneuver started, one set failed again, while the flight control system never switched to data from the second set. As a result, onboard computers were not receiving data about critical parameters required for properly completing the orbit correction, such as orientation of the spacecraft in space, velocity and altitude.

If confirmed, this crash scenario would likely implicate deficiencies in the development or testing of the flight control system and its software rather than any mechanical problem of the propulsion system, which was implied in the initial statement about the incident. [emphasis mine]

The highlighted sentence says it all. The serious quality control problems that have hampered Russia’s space efforts remain, and in fact appear systemic throughout its entire aerospace industry. In fact, this failure of a planetary probe helps explain the many difficulties Russia has been having in its war in the Ukraine, attributable to these same issues.

Frank Rubio on ISS sets new record for an American in space

10:10 am

Though Frank Rubio was only supposed to do a six month mission, a leak on the Soyuz capsule that brought him and his two crewmates into space has resulted in all three doing a mission exceeding one year, and setting a new record for an American in space.

Today Rubio broke the old American record of 355 days, set by Mark Vande Hei in 2022. When they return on September 27, 2023, all three will have spent 371 days in space, the third longest manned mission in history, exceeded only by Sergei Avdeyev’s 381 in 1999 and Valeri Polyakov’s 437 in 1994-1995, both on Russia’s Mir space station.

Based on my interviews with Polyakov and Musa Manarov (who was on the first mission with Vladimir Titov to spend one year in space — 366 days total — in 1988) for my book Leaving Earth, it will take Rubio about one year to fully recover from this mission, though he will likely be able to function almost normally within a month or so.

It remains interesting that these American records set by Rubio and Vande Hei occurred because of decisions by the Russians, not the American space agency NASA. NASA has consistently resisted doing long missions on ISS, even though this is exactly the kind of medical research required if we are to send humans on multi-year missions to Mars and beyond. Even more embarrassing, the longest NASA planned mission, flying Scott Kelly for 340 days, was touted by NASA as a year-long mission, even though it was never going to and did not achieve that distinction.

In doing this research the Russians have always led, and appear to continue to do so on ISS.

Endeavour Dragon capsule carrying four astronauts safely splashes down

8:53 am

SpaceX’s Endeavour Dragon capsule safely splashed down shorty after midnight last night in the Atlantic off the coast of Florida, completing a six month mission for two Americans, one Russian, and one astronaut from the United Arab Emirates (UAE).

The UAE astronaut, Sultan Al Neyadi, flew as a paying passenger, obtaining his flight through the private space station company Axiom, which in turn purchased the ferrying services to and from ISS from SpaceX. The Russian flew as part of the barter deal that NASA presently has with Russia, with each flying astronauts on the other nation’s capsules at no cost in order to make sure everyone knows how to use them in case of emergency.

Several additional details: First, in the post-splashdown press conference SpaceX officials revealed they are presently building a fifth manned Dragon capsule to add to its fleet, and are also aiming to fly each as much as fifteen times. This suggests they are anticipating a lot of business hauling both NASA and commercial passengers into space.

Meanwhile, the Russian-launched crew on ISS that launched last September and includes American Frank Rubio is targeting a return-to-Earth on September 27, 2023. If so, they will have completed a 371 day flight, or almost thirteen months. This I think is the second longest human flight so far in space, exceeded only by Valeri Polykov’s fourteen-and-half month mission in the 1990s.

Russian engineers pinpoint approximate crash site of Luna-25

9:07 am

Russian engineers have pinpointed the approximate crash site of Luna-25 on the Moon as the 42-mile-wide crater Pontecoulant G, located at about 59 degrees south latitude, 66 east longitude.

Researchers from the Russian Academy of Sciences’ Keldysh Institute of Applied Mathematics have simulated the trajectory of the Luna-25 mission, figuring out where and when it crashed into the moon’s surface, the institute said in a statement on Telegram. “The mathematical modeling of the trajectory of the Luna-25 spacecraft, carried out by experts from the Ballistic Center of the Russian Academy of Sciences’ Keldysh Institute of Applied Mathematics, made it possible to determine the time and place of its collision with the moon,” the statement reads.

According to the institute, the spacecraft fell into the 42-kilometer Pontecoulant G crater in the southern hemisphere of the moon at 2:58 p.m. Moscow time on August 19.

The planned landing site, in Boguslawsky Crater at 73 degrees south latitude and 43 degrees east longitude, was many miles away.

Luna-25 lost after crashing on Moon

9:37 am

During its last major orbital burn, Luna-25’s engines apparently fired for longer than planned so that, instead of placing it into a lower orbit, the spacecraft was de-orbited and sent crashing onto the lunar surface.

The Russian space agency noted that all measures regarding the location of the spacecraft and establishing communications with it on August 19 and 20 yielded zero results. “Preliminary analysis results suggest that a deviation between the actual and calculated parameters of the propulsion maneuver led the Luna-25 spacecraft to enter an undesignated orbit and it ceased to exist following a collision with the surface of the Moon,” Roscosmos stated.

This is a tragedy for Russia, as this mission hoped to re-establish it as one of the major players in the exploration of the solar system. Instead, we once again have a data point suggesting significant quality control problems within Russia’s aerospace industry. Its misplaced focus on providing government jobs rather than actually building and quickly flying spacecraft and rockets results too often in failure.

Luna-25 fails to enter orbit for landing on Moon

12:23 pm

Though it is in lunar orbit, Russia’s Luna-25 lander today was unable to perform an engine burn as planned to place it in its final orbit for landing.

“Today, in accordance with the flight program of the Luna-25 probe, at 2:10 p.m. Moscow time, a command was issued to the probe to enter the pre-landing orbit. During the operation an emergency occurred on the space probe that did not allow it to perform the maneuver in accordance with the required parameters,” Roscosmos said.

Engineers are analyzing the issue, but no other information was released.

This issue could simply be the spacecraft’s computer aborted the engine burn because it sensed something not right, and that after some correction another burn can follow later. Under this circumstance the landing attempt would simply be delayed.

It is also possible something happened during that engine burn, and the spacecraft is either in an incorrect orbit, or might even be lost entirely. Stay tuned.

Luna-25 takes first image of lunar surface

9:07 am

Luna-25's first lunar image
Click for interactive map. Zeeman is located on the lower left.

Russia’s state-run press today issued the first picture taken by Luna-25 after entering lunar orbit two days ago. That picture, to the right and cropped and reoriented to post here, shows part of Zeeman Crater at 75 degrees south latitude and 135 degrees west, on the far side of the Moon. From the TASS announcement:

“The Luna-25 spacecraft, flying in a circular orbit as the Moon’s artificial satellite, has taken pictures of the lunar surface with television cameras of the STS-L system. The image, taken today at 08:23 Moscow time, shows the southern polar crater Zeeman on the far side of the Moon. The coordinates of the crater center are 75 degrees south and 135 degrees west,” the state corporation said. Roscosmos said the Zeeman crater is of great interest to researchers. Its rim rises eight kilometers above its relatively flat floor.

The picture shows Zeeman’s southern rim to the left, with its pockmarked crater floor to the right. The crater the lander is targeting, Broguslawsky Crater, sits in the opposite hemisphere of Zeeman, slightly closer to the south pole but on the Moon’s near side.

Chandrayaan-3’s Vikram lander separates from its propulsion module; Luna-25 in lunar orbit

9:08 am


Click for interactive map.

The two probes aiming to land in the high southern latitudes of the Moon in the next week are now both in lunar orbit and preparing for their planned landings.

First India’s Chandrayaan-3: With its propulsion module having completed the job of getting Chandrayaan-3 from Earth to lunar orbit, the Vikram lander today separated from that module in preparation for firing its own engines on August 23, 2023 and landing on the Moon.

Vikram needs to make several orbital adjustments before that landing attempt.

Second, Russia’s Luna-25 probe entered lunar orbit yesterday, where it will spend the next few days making its own orbital adjustments before attempting its landing on August 21st.

Vikram carries a small rover, Pragyan. Luna-25 is only a lander, though it has a scoop and will do analysis of the lunar soil below it. Neither is landing “near the south pole”, as most news sources are saying. They are landing at latitudes comparable to landing in the Arctic on Earth, on the northern coast of Alaska. As such, neither will find out anything about the question of remnant ice in south pole’s permanently shadowed regions.

Russia considering flying Proton rockets after 2025

9:19 am

According to a story today in Russia’s state-run TASS news outlet, the Khrunichev design bureau that builds Russia’s Proton rocket is in negotiation with Kazahkstan to use all the remaining Proton rockets available, even if that requires additional launches after 2025, the date Roscosmos had previously announced as when all Proton launches will cease.

The Khrunichev Center (part of the state-run space corporation Roscosmos) is actively working on future cooperation with the Kazakh side, including with regard to the use of the Proton carrier rocket, the center’s CEO Alexey Varochko told TASS. “The Khrunichev Center is actively working on various scenarios of mutually beneficial cooperation with the Kazakh side, including those involving the Proton carrier rocket,” Varochko said.

According to the official, the possibility of using Protons after 2025 may be considered only if both Russia and Kazakhstan give their consent.

It sounds like Khrunichev has some spare Protons, and wants to make some money from them, even if Roscosmos has forbid it. It also appears that there is political infighting within Roscosmos about the retirement of Proton and resulting the loss of government jobs at Khrunichev.

Chandrayaan-3 reaches final lunar orbit for landing

9:12 am


Click for interactive map.

India’s Chandrayaan-3 spacecraft completed its final lunar orbital engine burn today, placing it in the correct orbit to release the lander Vikram, carrying the Pragyan rover.

The release is scheduled for tomorrow, with the landing targeting August 23, 2023. This will be India’s second attempt to softland an unmanned probe on the Moon. The Vikram lander of Chandrayaan-2 failed in 2019 during its final engine burn above the surface, crashing thereafter. Engineers at India’s space agency ISRO spent several years upgrading that lander to better insure this new attempt would succeed.

The lander has been given more ability to manoeuvre during the descent, the mission allows for a bigger 4 km x 2.4 km area for landing, more sensors have been added, one of the thrusters has been removed, and the legs of the lander have been made sturdier to allow for landing even at slightly higher velocity. More solar panels have also been added to ensure that the mission can go on even if the lander does not face the sun. More tests to see the capability of the lander in different situations were carried out to make Chandrayaan-3 more resilient.

Both Vikram and Russia’s Luna-25 lander, scheduled for touchdown on August 21, will land in the high southern latitudes of the Moon, at about 70 degrees. They are not going to the Moon’s south pole, as many news reports claim.

After almost two decades of development, Russia today used its Soyuz-2 rocket to launch Luna-25, its first lander to the Moon since the 1970s.

The link is cued to the live stream, just prior to launch. It will take several days to get to the Moon and enter orbit, make some orbital adjustments, then land in Boguslawsky crater, as shown on the map to the right. It is likely its landing will occur before India’s Chandrayaan-3 lands on August 23rd but not certain, depending on the adjustments needed in lunar orbit. Both could even land on the same day.
