Russia considering $100 million tourist spacewalks

Roscosmos is considering offering future space tourists the chance to do their own spacewalk for $100 million price tag.

“We are discussing the possibility of sending tourists on spacewalks,” Vladimir Solntsev, the head of Russian space company Energia, told Russian tabloid Komsomolskaya Pravda. “Market analysts have confirmed this: wealthy people are ready to pay money for this,” Solntsev told the paper.

He said the cost of such a trip could be around $100m (€80m), “possibly less for the first tourist”. The tourists will be able to “go out on a spacewalk and make a film, (or) a video clip”.

The article also reiterates Russia’s plan to put tourist accommodations in its next ISS module.

While the original news source for this story, Pravda, is generally not very trustworthy, I tend to believe this. It is definitely doable, and would give the Russians another way to make money, faced with the reality that they will soon be losing NASA as a customer for flying its astronauts to ISS. It also demonstrates that Russia recognizes that it will not be able to charge tourists the $75-$90 million or so per ticket it has been charging NASA. NASA was over a barrel, and thus the Russians could jack up the price. Tourists however will have the option of walking away, and thus the price per ticket will have to come down. For Russia to get the same money, they will need to offer more.

Problem with new ISS robot arm hand

Update: Software patch fixes robot arm latching mechanism. (Hat tip reader jburn.)

Less that a week after astronauts did a spacewalk to install a new latching end effector on the end of one of the station’s robot arms NASA has decided to do another spacewalk to put the old “hand” back on.

Hints of an issue cropped up during the previous spacewalk when two of the six Expedition 54 astronauts—NASA’s Mark Vande Hei and Scott Tingle—replaced the end effector, called LEE-B, but ground teams were unable to communicate with the mechanism. “The spacewalking crew demated and remated the connectors and ground teams were able to power up the arm to an operational state on its secondary communications sting leaving the arm operational but without a redundant communications string,” a NASA statement reads.

After several days of troubleshooting, NASA and the Canadian Space Agency—which built the 57.7-foot (17.6-meter) long Canadarm2—said the decision was made to use the upcoming spacewalk to re-install the old LEE-B to restore the redundant capability with the arm. The space agency said if Canada and its robotics specialists find a way to solve the issue, the Jan. 29 spacewalk could be delayed.

Scientists demonstrate first space navigation on ISS using pulsars

The stars are ours! Scientists using an x-ray telescope installed on ISS have demonstrated it is possible to pinpoint the location of a spaceship and thus navigate through space using pulsars.

In the SEXTANT demonstration that occurred over the Veteran’s Day holiday in 2017, the SEXTANT team selected four millisecond pulsar targets — J0218+4232, B1821-24, J0030+0451, and J0437-4715 — and directed NICER to orient itself so it could detect X-rays within their sweeping beams of light. The millisecond pulsars used by SEXTANT are so stable that their pulse arrival times can be predicted to accuracies of microseconds for years into the future.

During the two-day experiment, the payload generated 78 measurements to get timing data, which the SEXTANT experiment fed into its specially developed onboard algorithms to autonomously stitch together a navigational solution that revealed the location of NICER in its orbit around Earth as a space station payload. The team compared that solution against location data gathered by NICER’s onboard GPS receiver. “For the onboard measurements to be meaningful, we needed to develop a model that predicted the arrival times using ground-based observations provided by our collaborators at radio telescopes around the world,” said Paul Ray, a SEXTANT co-investigator with the U. S. Naval Research Laboratory. “The difference between the measurement and the model prediction is what gives us our navigation information.”

The goal was to demonstrate that the system could locate NICER within a 10-mile radius as the space station sped around Earth at slightly more than 17,500 mph. Within eight hours of starting the experiment on November 9, the system converged on a location within the targeted range of 10 miles and remained well below that threshold for the rest of the experiment, Mitchell said. In fact, “a good portion” of the data showed positions that were accurate to within three miles. “This was much faster than the two weeks we allotted for the experiment,” said SEXTANT System Architect Luke Winternitz, who works at Goddard. “We had indications that our system would work, but the weekend experiment finally demonstrated the system’s ability to work autonomously.”

I think everyone who is interested in interstellar space travel has assumed since the discovery of the first pulsars that they would end up serving as the future north star for interstellar travelers. This experiment shows us how it will be done.

Well read science fiction fans should recognized the literary reference in the tagline.

Russia to launch luxury hotel room module to ISS?

Capitalism in space: Roscosmos is considering a plan to launch a hotel module to ISS where it could house tourists for profit.

According to a detailed proposal seen by Popular Mechanics, the 20-ton, 15.5-meter-long module would provide 92 cubic meters of pressurized space. It would accommodate four sleeping quarters sized around two cubic meters each and two “hygiene and medical” stations of the same volume. Each private room would also have a porthole with a diameter of 228 millimeters (9 inches), while the lounge area of the module would have a giant 426-millimeter (16-inch) window.

The external structure of the tourist module looks like the Science and Power Module, NEM-1, which Russia is currently building for the International Space Station. The second NEM module had originally been on the books in the station’s assembly scenario, but the Russian government funded only one module. It will serve primarily as a science laboratory and a power-supply station for the ISS.

Now, Russia’s prime space station contractor, RKK Energia, came up with a scheme to pay for the second NEM module through a mix of private and state investments. To make profit, the NEM-2 would be customized for paid visitors.

Makes sense to me. Russia doesn’t really have the money right now to fund a big deep space exploration program. Better they aim for profits in space, as that will keep them in the black and provide them the capital they presently lack.

Soyuz launches new crew to ISS

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

Since the capsule only has to fly to ISS in low Earth orbit, it did not use the Fregat upper stage that failed in another recent Soyuz launch.

This launch probably clinches Russia’s lead over SpaceX for the most successful launches in 2017. At the same time, the U.S. overall will still win handily, with its most total launches in this century.

28 United States
19 Russia
17 SpaceX
15 China

I will be publishing a complete table of the launches with analysis, as I did last year, once the year is complete.

Russia astronauts have found bacteria living on the outside of ISS

Russia astronauts have found bacteria that was not intentionally brought into space living on the outside of ISS.

They are being studied on Earth but most likely they don’t pose any sort of danger, Russian cosmonaut Anton Shkaplerov told TASS on Monday. According to him, during spacewalks from the International Space Station under the Russian program, the cosmonauts took samples with cotton swabs from the station’s external surface. In particular, they took probes from places where the accumulation of fuel wastes were discharged during the engines’ operation or at places where the station’s surface is more obscure. After that, the samples were sent back to Earth.

“And now it turns out that somehow these swabs reveal bacteria that were absent during the launch of the ISS module. That is, they have come from outer space and settled along the external surface.”

I suspect it is a bit of hyperbole to say the bacteria came from outer space. It more likely came from either the station itself, or later spacecraft docking with the station. At the same time, the article is vague about what has been discovered. For example, it says nothing about the bacteria itself.

Beer on Mars

Capitalism in space: Budweiser’s goal to eventually brew beer on Mars will take its next step with the launch to ISS of a beer experiment in December.

To get the ball rolling, the famous beer brand is partnering with the Center for the Advancement of Science in Space, which manages the ISS U.S. National Laboratories, and Space Tango, a payload development company that operates two commercial research facilities within the National Laboratory.

Working with Budweiser’s innovation team, the group will send two barley-based experiments to the ISS as part of the next SpaceX cargo supply mission, scheduled for December 4. Budweiser’s barley seeds will stay in orbit for around a month before returning to Earth for analysis.

Seems right to me.

NASA forces retraction of astronaut vision study due to privacy issues

NASA has forced the retraction of an important science paper researching the damage to vision for astronauts on long spaceflights because of a concern the privacy of the astronauts might be violated.

According to the first author, the paper included information that could identify some of the astronauts that took part in the study — namely, their flight information. Although the author said he removed the identifying information after the paper was online, NASA still opted to retract it. But a spokesperson at NASA told us the agency did not supply the language for the retraction notice. The journal editor confirmed the paper was retracted for “research subject confidentiality issues,” but referred a question about who supplied the language of the notice back to NASA.

…According to first author Noam Alperin of the University of Miami Miller School of Medicine in Florida, the paper “Role of Cerebral Spinal Fluid in Space Flight Induced Ocular Changes and Visual Impairment in Astronauts” showed that visual damage caused by long space flights resulted from tiny shifts in the volume of spinal fluid — not vascular changes, as many experts had previously thought.

Protecting the health privacy of the astronauts is something NASA and the doctors that work with them are legally required to do. However, in this case the paper had been scrubbed of this information a long time ago. To force its retraction now when the actual. research was valid and important and the privacy of the astronauts was now protected seems an over reaction to me. Then again, NASA might be under legal pressure from the astronauts themselves, and thus forced to act.

Freon leak on U.S. part of ISS?

A news report today says that an accident in the U.S. portion of ISS caused a freon leak.

The report also said there was a leak of ammonia, and that he crew is not in danger from either leak.

The report is also very vague and sparse with information, and appears to come from the Russians, since it also says that the leaks suggest “systemic problems in the operation of the station’s U.S. segment.”

Russia to up ISS crew back to three

In order to integrate the new Nauka module, expected to launch in 2019, the Russians plan to increase their crew size on ISS back to three in late 2018.

[L]ong before the Nauka’s arrival, the Russian crew members aboard the ISS will have their hands full with various chores preceding the docking of the 20-ton spacecraft, which will increase the size and mass of the Russian Segment by almost a third. Moreover, once the module is in place, Russian cosmonauts are expected to labor into the 2020 to fully plug all the systems of the new room into their home in orbit. The total time required to integrate Nauka is expected to reach 2,000 work hours, including 11 spacewalks!

The preparations for the addition of the long-awaited module were scheduled to begin less than a year from now on Sept. 8, 2018, with the launch of the three members of Expedition 57 crew aboard the Soyuz MS-10 spacecraft. The launch will mark the first time since October 2016 that a Soyuz will lift more than one Russian cosmonaut.

Nauka is more than a decade behind schedule, which puts it in the same league as SLS and Orion. But then, Nauka, like SLS and Orion, is a government-built project, so no one should be surprised that it has taken so long. The goal isn’t the exploration of space. The goal is to create jobs, even if they don’t accomplish anything for decades.

NanoRacks successfully deploys its largest commercial smallsat from ISS

Capitalism in space: NanoRacks today successfully deployed its largest commercial smallsat yet from ISS.

NanoRacks Kaber Deployment Program allows for a larger EXPRESS class of satellites to be deployed from the International Space Station, up to 100 kilograms. NanoRacks deploys these Kaber-class satellites currently through the Japanese Experiment Module Airlock, and will shift deployments to the NanoRacks Airlock Module when the Company’s commercial Airlock becomes operational (planned for 2019).

The key here is that NanoRacks is making money providing launch services to smallsats in partnership with ISS and others. They act as the go-between between the smallsat companies and the NASA bureaucracy, thus earning money by simplifying NASA’s generally Byzantine approval and launch process for private satellite companies.

During its landing in April a manned Soyuz capsule became partially depressurized

During its landing in April a Soyuz capsule carrying three astronauts returning from ISS became partially depressurized at about five miles altitude.

The partial loss of pressure did not put the crew in jeopardy, Stafford said. A valve normally opens once the capsule descends to an altitude of five kilometers to allow outside air into the capsule. The crewmembers were also wearing pressure suits, as is standard procedure on Soyuz landings.

The incident occurred when a buckle from the parachute system hit a welding seam in the capsule as the parachute deployed.

There is a reason the Russians require astronauts to wear pressure suits while in a Soyuz capsule. During the return to Earth in 1971 of three cosmonauts from the first Russian space station, Salyut 1, the capsule depressurized and the three men died of suffocation.

Private company to build its own ISS airlock

Capitalism in space: The private company NanoRacks has raised the funds necessary to build its own ISS airlock and install it in 2019.

“The reason we want our own airlock is this airlock is going to be five times bigger than the current airlock, and it’s going to be far more commercial,” Manber said in a Sept. 27 presentation at the International Astronautical Congress in Adelaide, Australia. In addition to satellite deployments and experiments, he said the module will be commercial “real estate” on the station, with the ability to mount payloads on its exterior. “It’s getting us more into the real estate business and space station operations,” he said.

Manber said the module was on track to launch in 2019, carried to the station in the trunk of a SpaceX Dragon cargo resupply spacecraft. A formal manifesting of the payload on a resupply flight is now being finalized, he said, while the airlock itself is being manufactured.

What this suggests to me is that ISS might not go away in 2024, but instead slowly shift to private ownership and operation, all for profit. This deal appears to lay the groundwork for this shift.

NASA to extend use of private module on ISS

Capitalism in space: NASA has decided to extend the life of Bigelow’s module BEAM on ISS beyond its original two year test.

NASA’s original contract with Bigelow was to keep BEAM on ISS for two years and then jettison it, but NASA has concluded that BEAM has value as a storage compartment and wants to keep it there. NASA said the new contract would overlap the originally contracted test period, for a minimum of three years, with two options to extend for one additional year. A decision on whether to jettison it at that point or continue using it will be made thereafter.

The agency said that not only would NASA use it for stowage, but Bigelow will be allowed to use it “as a test-bed for new technology demonstrations.”

Using it makes a lot more sense than jettisoning it (the typical government way). This will also allow them to study the longevity in space of an expandable module.

Soyuz returns three astronauts to Earth from ISS

The successful return from ISS today of three astronauts by a Soyuz capsule marked the end of Peggy Whitson’s record-breaking nine-month mission.

When she launched to the International Space Station as part of the Expedition 50 and 51 crews on the Soyuz MS-03 mission, her tenure aboard the Station was due to end after approximately six months, landing with the same two crewmembers she launched with.

But a realignment of the Russian crew manifest and a desire on the part of Roscosmos to reduce Russian Station personnel from three to two until the launch of their new Mini-Research Module resulted in an ability, unplanned at her launch, to allow Dr. Whitson to remain aboard the ISS for nine months instead of six. Her planned six month stay, assuming it lasted the entire duration, would have seen Dr. Whitson break an important record for NASA – that of the most cumulative time in space for any NASA astronaut in history. Dr. Whitson broke that record on 24 April 2017, when she accumulated 534 days off Earth – breaking the record set by Jeff Williams in 2016. With the conclusion of her current mission, Dr. Whitson will have amassed a cumulative time of 665 days 22 hours 54 minutes in orbit, more than shattering Jeff Williams’s record and placing her 8th on the list of total time in space for a single person.

SpaceX launch today

SpaceX is scheduled to resume launches at Kennedy, after a month of range upgrades by the Air Force. You can watch it live here, or here.

Launch is presently scheduled for 12:31 Eastern time to send a Dragon capsule to ISS. At the moment all looks good for an on-time launch.

The launch was a complete success, including a picture-perfect first stage landing at Kennedy.

Time/PBS video documentary nominated for Emmy despite factual error in title

Fake news: The Time/PBS video documentary A Year in Space has been nominated for an Emmy award, despite a blatant factual error in the show’s title.

I haven’t seen the documentary, and so it might a great achievement. Nonetheless, this mission only lasted 340 days, not a year, and to call it “a year in space” is not only false, but an outright lie. For a news organization to start out this wrong, in the title, and then for it to get an Emmy nomination, tells us a great deal about the standards of accuracy in television news.

Tupperware in space!

Capitalism in space: Tupperware and NASA have partnered to provide space-grown gardens an artificial material for roots to grow and be watered.

First flown to the ISS in 2014, the Vegetable Production System, (aka the “Veggie” facility), is an experiment for growing plants in zero gravity in a plastic greenhouse. It consists of a collapsible plastic tent with a controllable atmosphere lit by red, blue, and green LED lamps to promote growth. Since dirt and space travel don’t mix, the seeds are embedded in rooting “pillows” that take the place of soil to retain water and give the roots somewhere to grow.

The problem is that the pillows don’t hold onto water very well, so the hydroponic system keeps drying out unless it’s tended regularly. Given how much it costs to keep an astronaut on the station, time spent watering the lettuce is about as economical as hiring a brain surgeon to mow the lawn, so a team led by Howard Levine at the Kennedy Space Center is working on some upgrades for the system.

One key example is the semi-hydroponic Passive Orbital Nutrient Delivery System (PONDS) being produced by Tupperware. With over 75 years of experience working with food-grade plastics as well as injection molding and other plastic manufacturing processes, Tupperware is producing a new disposable pillow made of plastic mesh that uses capillary forces and unusual geometries to replace gravity and hold water in like a zero gravity sponge while permitting root formation.

In other words, rather than design and built the pillows itself, as it would have in the past, NASA has hired Tupperware to build them. I am willing to bet this is saving NASA both time and money.

Growing cucumbers in space

New research growing cucumbers on ISS has found that the roots of these plants grew in the direction of water in weightlessness.

Plant roots grow to find water, according to a process known as hydrotropism. Roots are also influenced by gravity and tend to grow downwards, called gravitropism. To find out whether gravity or water had the greater influence on root growth, investigators grew cucumber plants in the microgravity environment on board the International Space Station. In their experiments, water (or hydrotropism) had more influence in controlling root growth.

“We will be able to utilize roots’ ability to sense moisture gradients for controlling root growth orientation and efficiently growing plants in future space farms,” said Dr. Hideyuki Takahashi, senior author of the New Phytologist study.

You can read the full science paper here.

This might sound obvious, but it isn’t. Past plant growth experiments on Mir and ISS had tended to show that plant roots did not know where to grow in weightlessness, suggesting that they needed gravity to guide the roots to water. Because of this, later experiments in space provided the roots complicated engineering to guide the roots to the water.

This experiment shows that maybe that complex engineering is not necessary, or at least could be simplified a bit. At a minimum it is crucial information engineers will need to design any future gardens for interplanetary spaceships with long term weightlessness.

Sierra Nevada picks ULA’s Atlas 5 for first two Dream Chaser cargo flights

Capitalism in space: Sierra Nevada has awarded ULA the contract for the first two cargo flights of Dream Chaser to ISS.

The announcement sets Dream Chaser’s first cargo flight to the International Space Station for launch from Cape Canaveral Air Force Station, Florida, in 2020. A second ISS cargo flight is contracted to lift off the next year. “ULA is an important player in the market and we appreciate their history and continued contributions to space flights and are pleased to support the aerospace community in Colorado and Alabama,” said Mark Sirangelo, corporate vice president of SNC’s Space Systems.

Financial terms of the contract were not disclosed.

Russians successfully launch Progress to ISS

A Russian Soyuz rocket successfully launched a Progress freighter to ISS early today.

That’s the second Russian launch in less than a week, after a very long pause caused by the discovery of corruption in one of their major engine factories. Though the Russians presently only have two launches scheduled for July, and none scheduled for August, I suspect that this will change in their effort to clear their launch backlog.

Worm grows 2 heads on ISS

The uncertainty of science: For reasons that are not yet understood, a flatworm fragment flown to ISS in a microgravity experiment regenerated with two heads.

But the most dramatic difference was a type of regeneration observed in one of the 15 worm fragments sent to the ISS. That worm returned to the scientists with two heads (one on each end of its body), a type of regeneration so rare as to be practically unheard of — “normal flatworms in water never do this,” Levin told Live Science. When the researchers snipped both heads off back on Earth, the middle portion regenerated into a two-headed worm again.

“And these differences persist well over a year after return to Earth!” Levin said. “Those could have been caused by loss of the geomagnetic field, loss of gravity, and the stress of takeoff and landing — all components of any space-travel experience for living systems going to space in the future,” he said.

The flatworms that flew in space showed other significant differences from the control group that stayed on Earth, further suggesting that for flatworms at least the environment of weightlessness causes more problems that were expected.

NASA considering using used first stages for Dragon cargo launches

Capitalism in space: With SpaceX’s successful launch on June 3 of a used Dragon cargo capsule to ISS, NASA is now considering using used Falcon 9 first stages for later cargo missions.

“That question has been posed,” Ven Feng, manager of the ISS Transportation Integration Office at NASA’s Johnson Space Center in Houston, said during a post-launch press conference Saturday. “We are looking at it,” he added. “We’re evaluating every aspect of it very carefully, and there is no schedule yet when we might go down that path.”

NASA officials made the same kind of cautious statements several years ago when SpaceX proposed flying a used Dragon capsule. In other words, they are going to do it, it just takes the bureaucracy time to mull the idea over and finally accept it.
