Bridenstine will ask Russia for explanation about drill hole

9:20 am

NASA’s administrator Jim Bridenstine, when asked by journalists about the decision by Russia to keep secret the origins of the drill hole in a Soyuz capsule that caused a leak on ISS, said he will politely beg Russia for some answers.

NASA Administrator Jim Bridenstine vowed Thursday to speak to the head of the Russian space agency after reports that the cause of a hole found on the International Space Station last year would be kept secret.

But he was careful to point out that he doesn’t want this situation to destroy the country’s relationship with Russia, a partner in space since 1975. “They have not told me anything,” Bridenstine told the Houston Chronicle during a question and answer session at a Houston energy conference. “I don’t want to let one item set (the relationship) back, but it is clearly not acceptable that there are holes in the International Space Station.”

Sure, let’s not offend those Russians so we can keep flying Americans on their capsules, even though they won’t tell us who drilled a hole in a Soyuz capsule prior to launch, then patched it badly so that it began leaking after a few months in space.

This kind of logic could only make sense in Washington government circles.

Roscosmos knows but will not disclose cause of Soyuz drilled hole

9:53 am

According to a statement by Dmitri Rogozin, the head of Roscosmos, the Russians now know what or who caused the drillhole in a Soyuz capsule, found when air began to leak from ISS in August 2018, but they will not reveal that information.

What happened is clear to us, but we won’t tell you anything”, Rogozin said at a meeting with the participants of a scientific youth conference. … We may have some secrets”, he said.

I wonder if NASA will accept this decision. I also wonder why this doesn’t raise the hackles of NASA’s safety panel, which seems so willing to stall the launch of American manned capsules for far less worrisome safety reasons, thus forcing us to use Russia’s Soyuz capsule instead.

UAE’s first manned flight launches this week on Soyuz

8:51 am

This article provides a nice detailed Arab perspective on the upcoming September 25 launch of the United Arab Emirates’ (UAE) first manned mission, sending one of their jet fighter pilots on a Soyuz to ISS for about a week.

The article not only also reviews the entire history of past Arab astronaut missions in space, the first on an American shuttle in 1985 and the second on a Soyuz in 1987, it summarizes the present-day space-related efforts throughout the Arab world, not just in the UAE. Good information in advance of this week’s upcoming launch.

New Russia Soyuz spacesuits interfere with Russia pee tradition

9:49 am

Only in Russia: The newly designed Russian spacesuits for use by astronauts during ascent and descent in the Soyuz capsule apparently do not have a fly that will allow the continuation of a long-standing Russian tradition initiated by Yuri Gagarin on his way to the launchpad for his historic spaceflight.

The Sokol-M prototype suit was designed as a replacement for suits worn during launches to the International Space Station (ISS) on Soyuz spacecraft. … The maker of the suits, the aerospace firm Zvezda, says they will be made of new materials and adaptable to different body sizes.

But the new design makes it impossible to carry out one particular ritual launched by the first man in space, Yuri Gagarin, who had to relieve himself on the back wheel of the bus that was taking him to the launch pad in 1961.

The stop has been replicated at every launch from the Baikonur launch pad and, many male cosmonauts and astronauts pee on the tyre for good luck – something that would be impossible in the new suit, according to its maker. Female astronauts are not obligated to participate but some have brought vials of their urine to splash on the wheel instead.

“I’m not sure how they will be able to (carry on the tradition), since we haven’t designed the fly,” said the Zvezda director, Sergei Pozdnyakov, quoted by Russian agencies. “We have the design specifications. They don’t state that it’s necessary to pee on the wheel. The design specifications would need to be adapted.”

I suspect, knowing how important traditions and rituals are to the Russians, that the Russian government will require a design change to allow this tradition to continue.

Soyuz successfully docks to ISS on second attempt

9:37 pm

An unmanned Soyuz capsule successfully docked to ISS tonight at a different docking port than the port where a failed component in the radar system caused the first attempt to be aborted two days ago.

This successful automatic docking confirms that the radar equipment on the other port was the problem. While manual manned dockings can occur there, the Russians will not be able to use it for unmanned Progress freighters until they get the faulty amplifier in the radar system fixed. To fix it will require a spare part and a spacewalk, and at the moment the Russians have said nothing about whether they have the part at the station.

Russian astronauts move older Soyuz to clear port for new Soyuz

9:02 am

Russian astronauts today undocked their older Soyuz MS-13 Soyuz from its docking port and manually docked it to the port with the technical issue, thereby clearing a different but functioning port for the unmanned Soyuz MS-14 capsule that failed to dock last week.

From the report it sounds like the Russians also did a test during the manual docking of the problematic docking radar on the older port, but no information about this has been released.

The unmanned MS-14 Soyuz will now make its second automatic docking attempt tomorrow, using the the cleared port.

Unmanned test Soyuz aborts docking to ISS

8:39 am

Astronauts on ISS were forced to abort the docking of an unmanned upgraded Soyuz capsule today when it appeared to have problems locking onto its docking port.

According to NASA, Soyuz MS-14 entered an orbit above and behind the ISS, which would bring the spacecraft back into the vicinity of the outpost 24 hours later. However within an hour after the failed docking, the mission control in Korolev told the ISS crew that the next docking attempt would not be made until at least August 26 after a series of tests. Head of flight operations in Korolev Vladimir Soloviev informed the cosmonauts that ground specialists had narrowed down a potential root cause of the failure during docking to a “bad signal amplifier” in the Kurs-P avionics system aboard the station. Soloviev instructed the crew to swap the suspected amplifier for a new one and then conduct a test of the Kurs-P system. Provided the ongoing analysis confirmed the initial failure scenario and the in-orbit tests went successfully, another rendezvous attempt could be made in around 48 hours, between 08:00 and 09:00 Moscow Time on August 26. Soloviev asked the crew members whether they knew where the components in question had been located to which the cosmonauts said that they had remembered it approximately but asked for reference photos to be sent to them.

Assuming this is the same docking port the Russians have used for previous Soyuz and Progress dockings, the amplifier would have had to fail since the last docking.

UPDATE: It appears that they are instead going to use a different Russian docking port on ISS for the second docking attempt, thereby bypassing the suspect docking system.

Russia and ULA successfully complete rocket launches

9:05 am

Russia and ULA both successfully placed spacecraft into Earth orbit today.

Russia sent an unmanned upgrded Soyuz capsule to ISS, filled with cargo, in a test flight that also tested a new upgraded version of the Soyuz rocket.

According to Navias, this Soyuz launch is a critical shakedown flight to test the performance of the upgraded Soyuz capsule and the Soyuz 2.1a booster before the first crewed flight on the rocket in March 2020.

“The Soyuz 2.1a booster, equipped with a new digital flight control system and upgraded engines, is replacing the Soyuz FG booster that has been used for decades to launch crews into space,” NASA officials wrote in a statement. “The Soyuz spacecraft will have an upgraded motion control and navigation system, as well as a revamped descent control system,” they added.

The mission will also help Roscosmos develop a cargo version of the Soyuz capsule capable uncrewed reentry to return experiments and other gear to Earth, Navias said. Russia’s Progress cargo ships can currently only deliver supplies, and are filled with trash and discarded at the end of their missions.

ULA in turn launched an Air Force GPS satellite in the last launch of the Delta-4 Medium version of its Delta rocket family.

The leaders in the 2019 launch race:

13 China
13 Russia
10 SpaceX
6 Europe (Arianespace)
4 India
4 Rocket Lab
4 ULA

The U.S. leads Russia and China 19 to 13 in the national standings.

Russia launches and docks new Progress freighter to ISS

9:20 am

Russia today launched and quickly docked a new Progress freighter, to ISS, with the trip taking slightly over three hours.

I think this might have been the fastest flight to ISS, though if not it is certainly among the fastest.

The leaders in the 2019 launch race:

11 China
11 Russia
9 SpaceX
5 Europe (Arianespace)
4 India

The U.S. continues to lead in the national rankings, 15-11.

Russia launches communications satellite

8:52 am

Using its Soyuz rocket the Russians today launched a satellite aimed at providing communications to Russia itself.

The satellite, while apparently providing civilian communications services, was a Russian government project. It is not commercial as we would define it in the west.

The leaders in the 2019 launch race:

11 China
10 Russia
9 SpaceX
5 Europe (Arianespace)
4 India

The U.S. continues to lead China 15 to 11 in the national rankings. At the moment it also looks like Russia has a chance to top 20 launches in 2019, which would make this its best launch year since 2015. This suggests that they have finally begun to recover from the discovery in 2017 that an engine contractor was using substandard welding materials to pocket some extra cash, thus causing many launch failures.

Soyuz launches new crew to ISS

7:08 pm

The Russians today launched and docked a new crew to ISS using their Soyuz rocket and capsule.

This launch puts Russia ahead of SpaceX in the 2019 launch race, the first time Russia has been ahead of SpaceX in almost two years. It also puts Russia in a tie with China for the lead, also something that has not been the case in two years. The leaders:

9 China
9 Russia
8 SpaceX
5 Europe (Arianespace)

The U.S. still leads 14-9 over China and Russia in the national rankings.

Russian Soyuz rocket successfully launches 33 satellites into orbit

10:56 pm

In its first Vostochny launch in 2019, Russia today used its Soyuz rocket to successfully launch a variety of weather, engineering, and Earth observation satellites totaling 33 into orbit.

As I write this the satellites are in orbit but have not yet been deployed by the rocket’s Fregat upper stage, a process that will take several hours as it moves them into a variety of orbits.

Many of the smaller satellites on this rockets are commercial cubesats, and are Russia’s effort to regain some of its lost commercial business that had been captured by SpaceX. They are also a sign of the changing launch business. Previously Russia’s commercial flights were all on its larger Proton rocket because the satellites were larger. Now the business is shifting to the smaller and recently more reliable Soyuz, because smaller satellites are beginning to dominate the industry.

The leaders in the 2019 launch race:

9 China
8 SpaceX
6 Russia
5 Europe (Arianespace)
3 India
3 Rocket Lab

The U.S. continues to lead China 14 to 9 in the national rankings.

Soyuz has problem during return to Earth

7:51 am

In returning three astronauts safely to Earth yesterday from ISS the Soyuz spacecraft experienced a technical problem immediately after its engines had fired, causing it to go to a backup system.

Moments after the completion of the braking maneuver, the emergency signal was heard inside the Descent Module and the communications between the crew and mission control discussed a failure of the first manifold in the integrated propulsion system of the Soyuz spacecraft and the switch to the second manifold. Kononenko first reported K1B (Manifold DPO-B) emergency at 05:02:54 Moscow Time and subsequently confirmed a switch to the second manifold. NASA later confirmed the problem, but did not provide any details.

There is no explanation what the “first manifold” is, though I suspect it is a direct translation from Russian for their term for a primary system. That the system automatically switched to its back-up is a good thing. That there was a failure of the primary system is not.

Once again, this raises more questions about the quality control throughout Russia’s aerospace industry. While so far none of the recent Soyuz problems, which have also included a launch abort and a still-unexplained drilled hole, have caused a loss of life. I fear that soon or later they will.

Russia to launch two more American astronauts on Soyuz

9:02 am

A news report from Russia today announced that NASA has extended its contract with Roscosmos so that two more American astronauts will fly to ISS using a Soyuz rocket and capsule.

Russia and the United States have agreed on two additional places on board of Soyuz carrier rockets for journeys of NASA astronauts to the International Space Station (ISS), Roscosmos Executive Director for Manned Programs Sergei Krikalyov told TASS. “The documents have been approved,” Krikalyov said adding that it the procedure to sign the papers took place before a recently reported incident with Crew Dragon spacecraft.

According to Krikalyov, there was no new draft of the document as it was “Simply an update to the previously signed contract, everything was in work order and there was no solemn ceremony to mark the signing of the documents.”

This agreement practically guarantees that there will be no Americans flying on American-built spacecraft in 2019. Rather than push SpaceX and Boeing to get their technical problems solved quickly so they can start flying, NASA can continue to slow-walk their development by going to the Russians. For NASA bureaucrats, using the Russians is to their advantage. Any failures can be blamed on the Russians, not NASA due diligence, which would be the case if an American privately-built capsule failed.

Moreover, slow-walking the American spacecraft helps NASA avoid further embarrassment with its own manned system, SLS/Orion, which is years behind schedule. By slowing the private capsules, the delays with SLS/Orion won’t seem so bad.

In other words, NASA’s approach here favors itself and the Russians over the interests of our country and American private companies. It is too bad no one in the Trump administration notices, or cares.

Rogozin: Investigation into Soyuz sabotage to continue on ISS

9:22 am

In his remarks to journalists today Roscosmos head Dmitry Rogozin also said that the Russian investigation into the hole that was drilled in a Soyuz capsule last year is not over, and that they plan to do further “experiments” on ISS.

“The samples collected on the ISS are insufficient for final conclusions. Apparently, additional experiments in orbit will be required,” Rogozin said.

What those “additional experiments in orbit” will be was not explained. I suspect he is referring to the security cameras the Russians are installing on their part of ISS, with the hope of catching the saboteur in the act.

What I think is going on here is that they have not been able to uncover who did this on the ground, and are now trying to imply it might have been sabotage by a U.S. astronaut. Rogozin can’t say this outright, because he wants to keep good relations with the U.S. in the partnership on ISS. He can hint at it, however, and let his own press run with it.

Russia successfully launches manned Soyuz to ISS

11:43 am

Update: The Soyuz rocket has successfully placed the manned Soyuz capsule into orbit.

The leaders in the 2019 launch race:

3 SpaceX
3 China
2 Europe (Arianespace)
2 Russia

The U.S. still leads China 4 to 3 in the national rankings.

Initial post: The Russians are right now counting down to a 3:14 pm (eastern) manned Soyuz launch to ISS.

A live video stream of the launch is available at the link from both NASA and the Russians. I have embedded the Russian stream below the fold. It has little narration, and so avoids the annoying propaganda stuff that the NASA feed is littered with.

This manned launch is a bit more interesting in that it is attempting to put in space the three astronauts who were on the aborted October launch. This is also only the second manned Soyuz launch since that abort, so there remains a bit of nervousness about it.

A Russian speaks truth to power about Roscosmos

10:40 am

Link here. The article outlines the obvious Russian ambivalence towards the success of SpaceX’s manned Dragon capsule this week, and then provides some insightful comments about this ambivalence from a Russian.

One person who would probably know is Vadim Lukashevich, a Russian-based space expert. He was fired from an aerospace think tank at Skolkovo in 2015 after writing articles opposing the transformation of Roscosmos from a government agency into a state corporation. On Monday, he gave an interview to Russian television station Moscow 24, which was published on YouTube and translated for Ars by Robinson Mitchell.

Lukashevich then proceeds to describe what readers of Behind the Black already know, but in much greater detail: The Soyuz capsule is outdated and cannot compete technologically or economically with SpaceX’s Dragon. Their business model of earning money by selling seats on it is over. And the Russian government is apparently unable or unwilling to do what must be done to make them competitive again. Its decision to form a single giant government-controlled aerospace corporation to run Russia’s entire space industry has failed, and they seem unable to recognize this.
