India unveils spacesuit for Gaganyaam manned mission

8:24 am

The new colonial movement: India’s space agency ISRO this week unveiled the spacesuit it is designing for the Gaganyaam manned mission scheduled for 2022.

The new space-suit mentioned above has been developed by ISRO at its Vikram Sarabhai Space Centre over the last two years. ISRO showcased the space suit for the Gaganyaan crew at the Bengaluru Space Expo for the first time ever. As per reports, ISRO has developed two of such space suits to date and will also develop a third one prior to the testing of the manned mission in 2022. The space suit comes with a capacity of one oxygen cylinder that claims to hold enough oxygen for 60 minutes.

This suit is not being built for spacewalks, but as a backup should the spacecraft itself develop a leak.

More aerospace problems in Russia

9:31 am

Two stories out of Russia today suggest that the serious quality control problems plaguing its aerospace industry have not been brought under control.

According to the second article the launch delay is because a Russian satellite manufacturer is behind schedule and might not deliver needed parts for the satellite’s assembly in time. I suspect the delay might also be related to the first article, as this satellite will launch on the brand new launchpad where they have discovered the cavities below ground.

That these cavities were not pinpointed during construction is very troublesome. One of the reasons SpaceX’s Boca Chica launchsite in Texas is taking as long as it is getting built is that the company had to make sure the soft beach property was structurally sound for rocket launches. That the Russians missed this speaks poorly again of their quality control.

Delays are common in the rocket industry, but in the context of Russia’s other space-related problems, the delay suggests a wider problem.

SpaceX successfully launches communications satellite

9:12 am

Capitalism in space: SpaceX last night successfully launched a communications satellite as well as recovered the Falcon 9 first stage.

The biggest news here is how routine the landings of the first stage have become, getting its first mention eight paragraphs into the article above, with its landing described almost as an aside. This was a new Block 5 first stage, and it will likely fly again within a relatively short period of time.

The leaders in the 2018 launch race:

24 China
16 SpaceX
8 Russia
6 ULA
5 Arianespace (Europe)

China still leads the U.S. in the national rankings, 24 to 23.

Second Chinese company completes suborbital rocket test

5:48 pm

For the second time this week, a Chinese “private” company successfully completed a suborbital rocket test.

This time the launch was by OneSpace, which should not be confused with the other company, iSpace. As with iSpace, the rocket used was a solid rocket, which once again makes me think it is doing work for the Chinese military, and is therefore not as independent or as private as Americans normally consider private companies.

Moreover, the launch was filmed by one of China’s spy satellites, also suggesting the military’s interest in this rocket company’s development. You can see both a ground-based and that satellite’s view of the launch at the link.

Japan to launch space elevator experiment to ISS

5:40 pm

When Japan launches its unmanned freighter to ISS on September 10, it will carry a two-cubesat engineering test of some of the concepts required to build a space elevator.

In the experiment, which will be the first of its kind in space, two ultrasmall cubic satellites, or “cubesats,” will be released into space from the station. They will be connected by a steel cable, where a small container — acting like an elevator car — will move along the cable using its own motor. A camera attached to the satellites will record the movements of the container in space, according to the Japanese newspaper The Mainichi.

Each cubesat measures just under 4 inches (10 centimeters) on each side. The cubesats will be connected by a 33-foot-long (10 meters) steel cable for the “elevator car” to move along, according to the report.

I wonder if this experiment will also test some of the technology needed for generating electricity using a tether. Over the decades there have been a number of experimental attempts in space of this concept, all of which have failed for a variety of reasons, all unrelated to the concept itself.

Jupiter’s weird magnetic field

11:34 am

New data from Juno has revealed that Jupiter’s magnetic field acts like it has three poles, one at each pole and another near the equator.

If Earth’s magnetic field resembles that of a bar magnet, Jupiter’s field looks like someone took a bar magnet, bent it in half and splayed it at both ends. The field emerges in a broad swath across Jupiter’s northern hemisphere and re-enters the planet both around the south pole and in a concentrated spot just south of the equator, researchers report in the Sept. 6 Nature.

“We were baffled” at the finding, says study coauthor Kimberly Moore, a graduate student at Harvard University.

They think the multiple poles are a result of the complexity of Jupiter’s inner core, which likely does not have the same kind of organization as a rocky terrestrial planet.

India teams up with France to prep for its first manned mission

10:25 am

The new colonial movement: India has signed a cooperative deal with France to provide them help in preparing for its first manned mission in 2022, now dubbed Gaganyaan by India’s press.

Following the signing of agreements between the two parties on Thursday, the agencies “will be combining their expertise in the fields of space medicine, astronaut health monitoring, life support, radiation protection, space debris protection and personal hygiene systems.”

The announcement was made by CNES [France’s space agency] president Jean-Yves Le Gall during the inaugural of Bengaluru Space Expo-2018 where he was the chief guest. It is being organised by the Confederation of Indian Industry along with ISRO and Antrix, the agency’s commercial arm, from September 6 to 8.

The two countries will also work together on other space research.

Hayabusa-2 scientists release updated landing schedule

10:20 am

The science team for Hayabusa-2 has released an updated landing schedule.

Two of the landers developed by the Japanese space agency will be deployed together by Hayabusa 2 on Sept. 21, and another landing probe provided by German and French scientists is set for its descent to Ryugu on Oct. 3.

Those landing attempts will be preceded by a landing rehearsal using the Hayabusa 2 spacecraft to approach within 100 feet (30 meters) of Ryugu next week. The spacecraft is scheduled to reach its closest point to the asteroid Sept. 12, low enough to fire and test its laser range finder, a navigation sensor to be used on future touch-and-go maneuvers to snag a sample of Ryugu for return to Earth.

Below is the very busy planetary probe schedule through January:

  • Week of September 12: Hayabusa-2 will do dress rehearsal of its Ryugu landing
  • September 21: Two of Hayabusa-2’s three Minerva-II mini-landers will land on Ryugu
  • October 3: Another Hayabusa-2 mini-lander, MASCOT, will land on Ryugu
  • October 3: The Parker Solar Probe makes first fly-by of Venus
  • Late October: Hayabusa-2 itself will land and grab a sample of Ryugu
  • November 26: The U.S. lander InSight will land on Mars.
  • December 3: OSIRIS-REx will arrive at the asteroid Bennu.
  • December: Chang’e-4 will land on the Moon’s far side.
  • January 1: New Horizons will fly past the Kuiper Belt object Ultima Thule.

During this time period Curiosity will also make two more drill attempts, and then resume its climb up Mount Sharp.

TESS releases its first batch of exoplanet candidates

9:59 am

The science team for the U.S.’s exoplanet space telescope TESS this week released its first batch of exoplanet candidates.

TESS scientists released the list so that other astronomers could make an initial determination as to whether these candidates are planets. There are 73 objects in this first batch, including some planets previously known from ground-based searches, says George Ricker, the mission’s principal investigator at the Massachusetts Institute of Technology in Cambridge. Perhaps 5 to 20% of the objects on the list will turn out to be false alarms, he says. Others, if confirmed, will join the ranks of newly discovered exoplanets.

Researchers expect TESS to find as many as 10,000 large planets. But its main goal is to discover and measure the masses of at least 50 small worlds no more than four times the size of Earth.

Meanwhile, Kepler has resumed operations despite being almost out of fuel. The science team there is attempting to squeeze every last ounce of data it can before the spacecraft’s fuel runs out.

Russia begins construction of Angara launchpad at Vostochny

9:52 am

Russia has begun the construction of the first Angara launchpad at their new Vostochny spaceport.

According to earlier reports, the Angara launch pad is to be completed by December 31, 2022. Construction costs are estimated at nearly 39 billion rubles ($565 million).

Somehow it seems to me that this construction is too expensive and is taking too long. A launchpad is essentially a specialized building on the surface. I don’t see why it should be so difficult or expensive to do.

China launches ocean survey satellite

9:42 am

Locations of two of China's launchsites

China today launched the third satellite in a constellation of ocean-observing satellites, using its Long March 2C rocket.

Though this is the same rocket that dropped its upper stage near a Chinese town in June, the launch came from the Taiyuan launch site, not the Xichang launchsite used in June, so it is unclear if the upper stages fell near populated areas. I would expect so, however, since Taiyuan is located in the middle of China even closer to populated areas than Xichang, as shown on the map to the right.

If the launch went north from Taiyuan, then those upper stages probably landed in Mongolia. I wonder if China has worked out an agreement with that country about dropping toxic first stages onto its territory.

Regardless, in the 2018 launch standings, China now leads the U.S. 24-22. The leaders in the race, with the leading U.S. companies broken out, are as follows:

24 China
15 SpaceX
8 Russia
6 ULA
5 Europe

As mentioned previously, with every launch for the rest of the year China will set a new annual record for itself.

Update on the Parker Solar Probe

8:49 am

Link here. The press release notes that the spacecraft’s instruments are one by one being made operational without problem and that it has also successfully completed a second course adjustment.

The release also provided a link to a page which will shows the probe’s present location. This is useful, as it also shows the probe’s position in relation to the Sun, Venus, and the Earth.

Curiosity to drill twice more on Vera Rubin Ridge

3:45 pm

Before they will resume the journey up Mount Sharp the Curiosity science team now plans two more drilling attempts on Vera Rubin Ridge.

The rover has never encountered a place with so much variation in color and texture, according to Ashwin Vasavada, Curiosity’s project scientist at NASA’s Jet Propulsion Laboratory in Pasadena, California. JPL leads the Mars Science Laboratory mission that Curiosity is a part of.

“The ridge isn’t this monolithic thing — it has two distinct sections, each of which has a variety of colors,” Vasavada said. “Some are visible to the eye and even more show up when we look in near-infrared, just beyond what our eyes can see. Some seem related to how hard the rocks are.”

Part of this drilling campaign will also include gaining a better understanding better their improvised drilling technique.

More details about Chinese suborbital launch earlier this week

9:56 am

Link here. The article really only provides one new detail about the flight itself, that the rocket used solid rocket motors. This fact, plus the overall secrecy, suggest to me that the company, iSpace, is doing its work for the Chinese military.

The article at the link also provides a good overview of the entire Chinese “private” smallsat rocket industry.

China is still run from the top, so any “private” rocket company must have the approval and support of the government. What makes China different from Russia, also ruled from the top, is the Chinese government’s willingness to encourage competitive independent operations, something the Russians has not done. The result is that China’s rocket industry is not stagnating, but growing.

“Unsteady hand” drilled hole in Soyuz

9:34 am

According to reports in Russia today, Roscosmos head Dmitri Rogozin suggested earlier this week that an “unsteady hand” had made several attempts to drill a hole in the Soyuz capsule.

“There is another version that we are not ruling out; that this was done deliberately in space,” Russian news agency RIA Novosti quoted Rogozin saying.

He indicated there were “several attempts to use a drill” by an “unsteady hand,” scraping the metal areas surrounding the hole, according to RIA Novosti. “We can cut short the idea that this was a technological mistake made by some specialist or other,” he added.

The vision that immediately came to my mind was that of a drunk technician, unhappy about pay, bad living conditions, and corruption, stumbling into the capsule, drilling the hole. Later, after he sobered up he realized the disaster he had created for himself and tried to fix it secretly.

Then again, it is dangerous to take seriously anything Dmitri Rogozin says. He could be trying to spin the situation to his advantage.

Saturn’s polar hexagonal vortex might tower high above clouds

3:35 pm

The uncertainty of science: A long term analysis of data from the probe Cassini suggests that Saturn’s north polar hexagonal vortex might tower many miles high above the planet’s clouds.

A new long-term study has now spotted the first glimpses of a northern polar vortex forming high in the atmosphere as Saturn’s northern hemisphere approached summertime. This warm vortex sits hundreds of kilometres above the clouds, in a layer of atmosphere known as the stratosphere, and reveals an unexpected surprise. “The edges of this newly-found vortex appear to be hexagonal, precisely matching a famous and bizarre hexagonal cloud pattern we see deeper down in Saturn’s atmosphere,” says Leigh Fletcher of the University of Leicester, UK, lead author of the new study.

“While we did expect to see a vortex of some kind at Saturn’s north pole as it grew warmer, its shape is really surprising. Either a hexagon has spawned spontaneously and identically at two different altitudes, one lower in the clouds and one high in the stratosphere, or the hexagon is in fact a towering structure spanning a vertical range of several hundred kilometres.”

There are many uncertainties here. For one thing, we have not yet even observed Saturn from up close through a complete year. We might be seeing random weather events having nothing to do with the gas giants overall planetary weather patterns.

Roscosmos re-inspecting all Progress/Soyuz capsules

9:48 am

The Russians are going to give all Progress and Soyuz capsules being prepared for launch a new inspection following the discovery that the airleak on the Soyuz docked with ISS had been caused by a technician on the ground prior to launch and covered up.

The consequences to Russia’s space industry because of this incident are going to be difficult to measure. It surely signals that they have still not got a handle on their quality control problems. In fact, it provides further proof that the technical work coming out of Russia is shoddy, sloppy, and filled with many forms of corruption, all circumstances that should give pause to anyone thinking of flying a product or themselves on a Russian-made product.

Worse, the centralized government-run space industry created by Putin is exactly the wrong thing for fixing these problems. Russia does not have a competitive and free aerospace industry. Everything is run by the government and based on the ability to wield political power rather the ability to demonstrate skill and quality in how you do your job.

With only five launches expected in 2019, Russia’s space program is sinking to the level of a third world country. This airleak disaster will only help it sink further.

One last note: I predicted this kind of disaster back in 2013, when the consolidation of Russia’s aerospace industry was announced by the Putin government. My prediction was not very difficult, nor especially brilliant, since disasters like this always occur from government-run top-down socialist/communist systems. One only has to be patient. It is only a matter of time before the system fails, and fails badly.

ISS airleak an accidental drill hole on ground

5:21 pm

The airleak last week on ISS in the orbital module of a Soyuz capsule was not caused by a micrometeorite but by an accidental drill hole made by a technician on the ground who then, rather than reporting it, sealed it and covered it up..

“The hole was made on the ground. The person responsible for the act of negligence has been identified,” the source told the news agency.

Another source said a worker apparently accidentally drilled the hole, but instead of reporting it, simply sealed it. The sealant held for at least the two months the Soyuz spacecraft spent in orbit, before finally drying up and being pushed out of the hole by air pressure.

According to a Moskovsky Komsomolets report, the hole was located near the toilet and covered by decorative fabric. The Russian crew members used an epoxy-based sealant with metallic additives to plug both the hole and a fracture in the outer hull of the Soyuz located behind it, the newspaper said.

Well, if anything is going to put an end to the resistance to using privately built American manned capsule, this should do it. This is also going to do a great deal of harm to the Russian desire to sell tourist seats on their Soyuz.

UAE names the two finalists for its first manned flight on Soyuz

9:15 am

The new colonial movement: The leader of Dubai yesterday named the UAE’s the two astronaut finalists, one of which will fly on a Soyuz to ISS sometime next year.

The ruler of Dubai has announced the names of two astronauts from the United Arab Emirates who will be heading to the International Space Station, a first for the Gulf nation. Sheikh Mohammed bin Rashid Al Maktoum, who also serves as the UAE’s vice president and prime minister, made the announcement on Monday on Twitter.

Sheikh Mohammed named the astronauts as Hazza al-Mansouri and Sultan al-Nayadi. Their missions are scheduled for next year.

No biographical information about these two men has yet been released, but I am willing to bet that some UAE politics played a part in their selection. This is not to say that they are unqualified (because both men were cleared to fly by the Russians) but to note the realities that always lurk within any government run space program.

SpaceX’s Big Falcon Rocket and the colonization of Mars

7:49 pm

Link here. Lots of details about what SpaceX wants to do, as well as the company’s request for help in areas it is weak.

Below the fold is the youtube video from the Mars Society conference last week which forms the basis of the article at the link.

I only have one comment at this time: I worry that SpaceX is developing a rocket, the BFR, that has no marketable value, at this time. They succeeded with the Falcon 9 and the Falcon Heavy because they could market them and make money from them. The commercial space industry needed these rockets that could fly at lower cost, and that has paved the way for SpaceX’s success.

There are real questions whether a similar market exists for BFR. To paraphrase a line from the movie Field of Dreams, it is possible that if they build it the customers will come, but few businesses succeed with that market strategy.

Russian official predicts only 10 launches for 2019-2020

9:24 am

How the mighty have fallen: A Russian official yesterday predicted that they will only do a total of 10 launches for the two year period from 2019 to 2020.

“Five launches are envisaged for 2019. Five launches of manned and resupply ships, and also of a nodal module are planned for 2020,” the vice-premier said at a meeting held at the Energia Rocket and Space Corporation on the problems of piloted cosmonautics in the process of fulfilling long-term space exploration programs. [emphasis mine]

The highlighted words reveal a second tidbit, namely that they apparently will not be launching the Nauka module to ISS in 2019, as previously announced.

In a related story, a Russian space official also confirmed that they will definitely cease flying American astronauts on Soyuz in April 2019, as per the NASA-Russian contract.

The second story does not mention the Soyuz flight seats that Boeing owns, obtained as part of the settlement of the Sea Launch partnership. I wonder about their status. Are the Russians going to block them? I also suspect that this second story might be a negotiating effort by the Russian government to press NASA into buying more flights, something NASA has so far not done.

Either way, the first story essentially places Russian in the bottom echelon of space-launch nations, ranking comparable to what India and Japan have been doing in recent years. Both these countries however expect to up their numbers, which makes Russia’s space future look even more dismal.

For the entire history of space, beginning with Sputnik, the Soviet Union/Russia had consistently dominated the world in annual launches. For them to have fallen so far tells us much about the failed socialist and centralized policies of the Putin government. They do not work. They never work. In fact, they cannot work.

Will someone please tell this fact to both the American Democratic Party, and the many people who continue to vote for its new socialist agenda?

Some debate at NASA over Opportunity

8:58 am

This story yesterday had the following interesting paragraph:

Members of Opportunity’s engineering team recommended a different plan, the person close to the mission says. Their idea was to actively try to communicate with Opportunity until the end of January 2019 — the end of the seasonal cleaning period. After that, they suggested passive listening until the end of 2019. But these recommendations were ignored by management in order to save money, this person says, meaning the agency could be risking abandoning a still-functioning rover. The Opportunity team reportedly didn’t receive formal notice of the plan until “minutes before JPL published its press release,” according to The Atlantic.

It appears that some on the science team do not feel that the present plan to listen closely for only 45 days, through mid-October, is sufficient, as it will likely require a dust devil to clear Opportunity’s solar panels, and dust devil season will not begin until November.

However, it is very likely wrong to blame the resistance by NASA management to this plan solely to a desire to save money. There are other considerations, such as tying up the Deep Space Network for this one rover when, as I noted yesterday, the October to January time period will be a very very very busy time for that network, with many important new planetary probe events. Seven different spacecraft will either be landing or doing fly-bys on four different solar system targets during that time. Tying the network up to listen for Opportunity will likely not work.

It seems to me that Opportunity should be recovered, if possible, but it also must receive a lower priority during this time period. After New Horizons’ January 1st fly-by of Ultima Thule it might be possible to devote more time then to listening, but I can see the logic, at least in this context, for reducing the listening time from October to January.

Hat tip Kirk Hilliard.

The upcoming very busy planetary probe season

12:08 pm

The next few months are going to be very busy and exciting for the planetary science community. Seven different probes will be either flying past or landing on four different solar system objects, with interesting events happening every few weeks:

  • September 21: One of Hayabusa-2’s mini-landers, Minerva-II-1, will land on the asteroid Ryugu
  • October 3: Another Hayabusa-2 mini-lander, MASCOT, will land on Ryugu
  • Late October: Hayabusa-2 itself will land and grab a sample of Ryugu
  • November 26: The U.S. lander InSight will land on Mars.
  • December 3: OSIRIS-REx will arrive at the asteroid Bennu.
  • December: Chang’e-4 will land on the Moon’s far side.
  • January 1: New Horizons will fly past the Kuiper Belt object Ultima Thule.

In addition, another Hayabusa-2 mini-lander will also land on Ryugu, sometime after Hayabusa-2’s landing. Moreover, as OSIRIS-REx and New Horizons approach their targets we shall see daily new and increasingly sharper images of both Bennu and Ultima Thule, prior to their arrival.

I expect from September to January there will be many many very cool images coming from space, on almost a daily basis.

How the Curiosity science team found soft rock for drilling

10:15 am

Link here. They very much wanted drill samples on Vera Rubin Ridge, but had twice found the rock too hard for Curiosity’s drill. So how did they pinpoint the spot, dubbed Stoer, where the drill finally worked?

In the absence of direct data on rock mechanical properties, we came up with three criteria that we could use to try to find a softer rock. (1) Did the bristles of the DRT brush leave scratches on the rocks’ surfaces? While not necessarily a direct indicator of what the rock strength would be when we drilled into it, we could at least say rocks that got scratched with the DRT had a softer surface than those that didn’t. (2) How well exposed are the white calcium sulfate veins? On some rock targets, like Stoer, we clearly see veins. On other targets, like Voyageurs, the veins are recessed into the rock. Recessed veins erode much faster than the surrounding bedrock because the surrounding bedrock is harder. Non-recessed veins tells us the bedrock may be similar in strength to the veins, or, if the veins stick out, the bedrock may be lower in strength. (3) What does the large-scale topography tell us? Broadly, Vera Rubin Ridge is a ridge because it is composed of hard rocks that are more resistant to erosion than their surroundings. We realized we might use this same logic to find softer rocks within the ridge by trying to drill in local topographic lows or at bases of scarps where the bottom of the scarp is eroding more quickly than the hard rocks on top.

The successful drill hole, Stoer, was thus down somewhat from to top of the ridge. As they prepare to move on, it appears they want to try again to drill at the top of the ridge. It also appears that the work described above has maybe found another location there where the rock might be soft enough for the drill.

As Mars dust storm clears, Opportunity remains silent

10:04 am

The Opportunity science team today provided a new update on the rover, noting that it remains silent even as the Martian dust storm is clearing.

With skies clearing, mission managers are hopeful the rover will attempt to call home, but they are also prepared for an extended period of silence. “If we do not hear back after 45 days, the team will be forced to conclude that the Sun-blocking dust and the Martian cold have conspired to cause some type of fault from which the rover will more than likely not recover,” said Callas. “At that point our active phase of reaching out to Opportunity will be at an end. However, in the unlikely chance that there is a large amount of dust sitting on the solar arrays that is blocking the Sun’s energy, we will continue passive listening efforts for several months.”

The additional several months for passive listening are an allowance for the possibility that a Red Planet dust devil could come along and literally dust off Opportunity’s solar arrays. Such “cleaning events” were first discovered by Mars rover teams in 2004 when, on several occasions, battery power levels aboard both Spirit and Opportunity increased by several percent during a single Martian night, when the logical expectation was that they would continue to decrease. These cleaning dust devils have even been imaged by both rovers on the surface and spacecraft in orbit (see https://mars.nasa.gov/resources/5307/the-serpent-dust-devil-of-mars/).

It appears however that if nothing is heard from Opportunity by sometime in mid-October, they will be very prepared at that time to begin shutting down ground-based operations here on Earth.

Scotland’s first commercial rocket test flight

9:34 am

Capitalism in space: A private smallsat rocket company, Skyrora, has successfully completed a suborbital test flight, the first commercial rocket test flight in Scotland.

Skyrora saw its 2.5 metre (9ft) projectile reach altitudes of almost four miles after taking off at the Kildermorie Estate in Ross-shire. Known as Skylark Nano, it accelerated to Mach 1.45 – more than 110mph.

One could also describe Skylark Nano as nothing more than a big model rocket. Nonetheless, the company is using this test flight to improve its chances to win the competition for some of the money the UK government will award to private companies in connection with the establishment of its new spaceport in Sutherland, Scotland.

Dates set for first landings on Ryugu

9:10 am

The science team for the Japanese probe Hayabusa-2 have set the dates for the first two landings on the asteroid Ryugu.

On 21 September, it will despatch the first of these piggybacked packages. A 3.3kg container known as Minerva II-1, which is mounted on the spacecraft, will deploy two robots known as Rover 1A and Rover 1B.

The 1kg “rovers” will actually move by hopping under the asteroid’s low gravity. Each one contains a motor-powered internal mass that rotates to generate force, propelling the robot across the surface. The rovers are equipped with wide-angle and stereo cameras to send back pictures from Ryugu.

Then, on 3 October, the mothership will deploy a lander called Mascot, which has been developed by the German Aerospace Center (DLR) in conjunction with the French Space Agency (CNES). Mascot, otherwise known as the Mobile Asteroid Surface Scout, is a 10kg instrument package that will gather a range of scientific data from the surface. It carries a wide-angle camera, a microscope to study the composition of minerals, a radiometer to measure temperature and a magnetometer to measure the magnetic field.

After it reaches the surface, Mascot can move its position only once, by jumping.

An earlier report had said that Hayabusa-2 would itself land late in October, but this report today leaves that landing date unstated.

First private patents filed for manufacturing materials on ISS

10:36 am

Capitalism in space: Two private companies, Proctor & Gamble and Made in Space, have filed the first private patents for the manufacture of either materials or supplies on the International Space Station.

These patents are very important, as they specifically describe doing manufacturing in space of objects that can be used in space. There have been many previous patents for research in space, but all have usually related to research for use on Earth.

Air leak on ISS

10:17 am

An air leak on ISS was detected yesterday, and pinpointed to cracks found in the spherical habitation module of one of the Soyuz capsule’s docked to the station.

According to Russian sources, the problem was found in the Habitation Module of the Soyuz MS-09 spacecraft, where the crew detected two small cracks, reaching 1.5 millimeters in size. Alexander Gerst apparently first discovered the leak.

The cosmonauts photographed the affected area and sent it to mission control for analysis. The first estimates indicated that the holes could be caused by meteor or debris strikes which punctured the hull of the spacecraft. Head of the Roskosmos State Corporation Dmitry Rogozin confirmed the incident but said that the problem had been resolved. According to Rogozin, the crew had to close off various sections of the station to isolate the leak.

According to ESA sources, the area of the leak was temporarily sealed with tape, while Russian cosmonauts were working on a permanent sealing patch. After some drop during the night, the air pressure inside the ISS was reported as stable near sea level. In the meantime, mission control informed the crew that all scheduled activities for August 30 had been cancelled.

The cracks do not pose a problem for using the Soyuz for returning to Earth, as the habitation module is discarded before de-orbit. The descent module appears unharmed.
