A full moon rises above Earth's horizon as the Russian Progress 75 (75P) cargo resupply ship, filled with trash, has separated from the International Space Station's Zvezda service module after spending a year docked with the orbiting lab. Progress 75 arrived on April 25, 2020 and departed the station on April 27, 2021, after which it safely burned up in Earth's atmosphere.

During Expedition 65, Russia launched its new, long-awaited Multipurpose Laboratory Module, also known as Nauka, to the International Space Station. Nauka docked with the ISS on July 29, 2021, after which it briefly misfired its thrusters and sent the station slowly tumbling in orbit. ISS flight controllers were able to fix the situation, and the astronauts were never in any danger, NASA said.

Nauka will serve as a science module for the Russian half of the orbiting lab. Here: a view of Russia's Nauka module docked with the International Space Station on July 29, 2021.

NASA Can Now Predict Radiation Risks for Astronauts on International Space Station | The Weather Channel – Articles from The Weather Channel |…

Posted: at 3:43 pm

Japanese Aerospace Exploration Agency astronaut Akihiko Hoshide poses for a photo after undergoing a generic blood draw in the European Laboratory/Columbus Orbital Facility (COF).

While Astronauts are out discovering the various facets of space, they also face several hazards. In addition to immediate risks like high-speed space debris, equipment malfunction and risky take-off and re-entry, a major, long-term threat is the constant exposure to space radiation. Now, to mitigate these risks, the US space agency NASA has developed a novel method to predict space radiation exposure on the International Space Station.

Space radiation originates from three primary sources: particles trapped in the Earth's magnetic field, particles shot into space during solar flares, and galactic cosmic rays, which originate outside our solar system. Exposure to such radiation causes changes in our DNA and increases the risk of diseases like cancer. This is why NASA has taken this initiative to protect astronauts from such hazards.

As gauging the long-term impact of the space radiation environment on the health of astronauts is challenging, scientists have attempted to measure the changes in an individual's chromosomes. The study's premise is to see how the sensitivity of an astronaut's DNA to radiation exposure on Earth can predict their DNA's response during spaceflight as measured by changes to their chromosomes.

The senior scientist Honglu Wu from NASA's Johnson Space Center in Houston said, "we wanted to know if it is possible to detect and measure radiation exposure damage in the bodies of astronauts, and if there were differences based on age, sex, and other factors that could be measured before they go into space.

"We hope to use these measurements to help develop and compare methods of protecting astronauts from radiation," he added.

Blood samples were taken by former NASA astronaut Chris Cassidy. Samples like these were taken before and after astronauts missions to space to measure radiation damage of astronauts in space.

Researchers studied astronauts' blood cells before they travelled to the station to determine their baseline chromosomal condition, against which any future alterations could be measured. Following that, these blood samples were subjected to gamma-ray radiation on Earth to see how quickly their cells accumulated these chromosomal alterations.

Earlier, people thought that the younger members are at a higher risk in the long-term since radiation exposure can take around 20 years to manifest into health complications like cancer. However, the research now showed that older crew members were more susceptible to chromosomal changes than the younger crew members.

"When thinking about going to Mars, we typically have thought it might be better to send older astronauts because of their experience and lower risk of developing cancer in their lifetime," said Wu. "Now, based on this new research, we know that we should study the age effects of radiation exposure more."

This study was published in the journal Nature-Scientific Reports and can be found here.

Astronauts and satellites watch Hurricane Henri from space as US Northeast braces for storm – Space.com

Posted: at 3:43 pm

As parts of the U.S. northeast brace for Hurricane Henri to make landfall in New York today (Aug. 22), astronauts and satellites are tracking the historic storm from space.

Henri, which reached category 1 hurricane status on Saturday, is forecast to make landfall on Long Island, New York by midday today, dropping torrents of rain on Connecticut and Rhode Island, according to the National Hurricane Center's morning update. Astronauts on the International Space Station spotted Henri from orbit on Saturday.

"We just flew over the East Coast and saw Hurricane Henri," NASA astronaut Megan McArthur wrote on Twitter while sharing a photo of the storm from space. "Stay safe friends."

The Goes-East weather satellite tracked Henri's approach to the U.S. East Coast over the last few days, as well as Hurricane Grace, which made landfall in Mexico on the eastern Yucatan Peninsula on Thursday. One video from the satellite shows both storms churning across the Atlantic while Henri was still a tropical storm.

NASA's Terra satellite spotted Henri in the Atlantic on Friday (Aug. 20) as it was building strength as a tropical storm.

"Around the time of the image, Henri was located about 400 miles (640 kilometers) southeast of Charleston, South Carolina, and was moving toward the northwest," NASA's Kathryn Hansen wrote of the image in a description. Henri was just shy of hurricane category 1 status at the time, she added.

Hurricane Henri is the first hurricane to make landfall in the New England area in nearly 30 years. The last to hit New England was Hurricane Bob in 1991, while Long Island was hit by Hurricane Gloria in 1986, according to the New York Times.

As of Sunday at 8 a.m. EDT (1200 GMT), Henri was located about 40 miles (65 kilometers) south-southeast of Montauk Point, New York with maximum sustained winds of 70 mph (110 kph), according to the National Hurricane Center.

Hurricane warnings are in effect for the Long Island area and the southern coast of New England, as are storm surge and flooding warnings. With the outer bands of Henri expected to lash a wide swath of the northeastern U.S., a tropical storm warning is in effect for a region that stretches from New Jersey to Massachusetts, including New York City.

Computing at the edge of space: HPE and Microsoft conduct International Space Station experiments – GeekWire

Posted: at 3:43 pm

If your cell phone went out 17 times a day, for anywhere from 1 second to 20 minutes, youd get a new wireless provider. Thats basically what astronauts on the International Space Station are dealing with, but they dont have that option.

Thats how Mark Fernandez of Hewlett-Packard Enterprise (HPE) explains the state of communications between the ISS and Earth and its one reason hes excited to have a computer on board.

Fernandez is principal investigator for HPEs Spaceborne Computer-2, which was launched to the International Space Station in February.

The communications continuity for the space station is very fragile, he explained. So we need to empower [astronauts] to be more autonomous. And by having Spaceborne Computer-2 board, not only does it build up their confidence, but it builds up their ability to solve their own problems without relying on Earth.

That makes the International Space Station an extreme case study for edge computing, the concept of bringing storage and processing closer to the source of data to improve speed and reduce the bandwidth needed for cloud computing.

Were seeing more scenarios move to the edge, and that is changing how developers think about writing applications, and how they think about bandwidth and the scarcity of bandwidth, said TomKeane,Microsoft Azure corporate vice president. And space, of course, gives you a great understanding.

For Microsoft, the project is part of a larger effort called Azure Space that also includes partnerships with SpaceX and others.

HPEs Spaceborne Computer-2 uses off-the-shelf servers and components encased in hardware designed for harsh environments. Microsoft and HPE have worked together to connect Spaceborne Computer-2 to Azure from orbit to enable advanced artificial intelligence applications on the ISS.

Theyre using standard and open-source tools such as Python and Linux containers to ensure that others can participate or build on their approaches in the future.

The companies announced Wednesday that theyve completed their first experiments. Theyve ranged from successful hello world message to tests on a potato that was grown onboard the ISS in zero gravity, to better understand the cause of its deformities.

But the big test so far has been an intensive analysis of astronaut genomes, seeking new clues about the impact of extended stays in space on the human body.

The raw data amounts to hundreds of gigabytes, an impractical size to attempt to transmit under the circumstances. Spaceborne Computer-2 is allocated two hours a week for downloads from the ISS over an aging system that uses Tracking and Data Relay Satellites (TDRS) to connect to base stations on Earth.

Instead, the companies took software developed by Microsoft and packaged it up into Linux containers to process astronaut genomes on Spaceborne Computer-2. Then they sent the details of any mutations down to Earth to analyze against National Institutes of Health databases and generate the results.

Thats a short little message that we can return back to the Space Station, Fernandez said. Its been taking weeks, if not months, to download that genome previously, whereas we can download in just a few minutes once weve processed at the edge.

The companies say theyve completed a total of four experiments so far, with four more underway and 29 more planned beyond that. Spaceborne Computer-2 is expected to be used for research projects at the ISS for two to three years.

Time is of the essence: Congress has authorized the ISS budget through 2024, but even if the budget is extended, its not expected to go beyond 2030.

Here’s How the Chinese Tiangong Space Station Compares to the ISS – Interesting Engineering

Posted: at 3:43 pm

For 22 years the International Space Station (ISS) was the only station in orbit (except for a period from1986 to 2001 when the Russian Mir station was in operation). Amultinational collaborative project involving five participating space agencies (United States, Russia, Japan, Canada, and the European Space Agency), the orbiting station dominated space, but now it has competition.

TheTiangong space station is being constructed in low Earth orbitbetween 340 and 450km (210 and 280mi) above the surface. Itsfirst module, theTianhe("Harmony of the Heavens") core capsule, was launched on 29 April 2021 and two more modules are set to be launched next year.

So, how will the new station compare to the ISS?

Let's start with the basics. How high in the sky is each space station? The ISS roams at an altitude of around400 km (258 mi), while Tinagong will orbit between 340 and 450km (210 and 280mi) above the surface. So basically, the two stations do not differ much on this criteria.

When fully loaded, theTiangong Space Station could have a mass of around 100 metric tons (220,500 lb), roughly one-fifth the mass of the ISS. Coincidentally this is around the size of the decommissioned Russian Mir space station.

Both the ISS and Tiangong use solar power to sustain themselves.The ISS's electrical system uses photovoltaics, where solar cells directly convert sunlight to electricity.Large numbers of cells are assembled in arrays to produce high power levels, but this process sometimesbuilds up excess heat that can damage spacecraft equipment.

To deal with this, the ISS uses radiators shaded from sunlight and aligned toward the cold void of deep space to dissipate heat away from the spacecraft.

Meanwhile, Tiangong uses two steerable solar power arrays located on each module. These make use of usegallium arsenidephotovoltaiccells to convert sunlight into electricity. The station also stores energy for the period when the orbiting station is no longer exposed to the sun.

At first, these two methods might sound very similar, but they do have important differences. The main one is that Tiangong uses solar arrays whereas the ISS uses "wings." These solar array wings often abbreviated SAW consist of two retractable "blankets" of solar cells and are the largest ever deployed in space.

Each wing weighs more than 2,400 pounds, can reach 35 metres (115ft) in length, and 12 metres (39ft) in width when extended.Altogether, the four sets of arrays can generate 84 to 120 kilowatts of electricity enough to provide power to more than 40 homes.

However, since the station is not always in direct sunlight, it also relies on lithium-ion batteries to see it through dark periods. These account for 35 minutes of a 90-minute orbit. The batteries are recharged when sunlight is present. Up until2017, the ISS relied on nickel-hydrogen batteries. These were replaced from 2017 to 2021 with more effective lithium-ion ones.

The Chinesespace station is set to be a third-generation modular space station, just like the ISS. Third-generation space stations are modular stations, assembled in orbit from pieces launched separately.

The Chinese space station is currently set to have three modules (the Tianhe core module, the Wentian Laboratory Cabin Module, and the Mengtian Laboratory Cabin Module) whereas the ISS has a whopping 16 modules, with two more scheduled to be added.The ISS is made up offive Russian modules (Zarya,Pirs,Zvezda,Poisk, andRassvet), eight U.S. modules (BEAM, Leonardo,Harmony,Quest,Tranquility,Unity,Cupola, andDestiny), two Japanese modules (theJEM-ELM-PSandJEM-PM) and one European module (Columbus).

The Tiangong space station is constructed around the Tianhe core module. This section is the main one and provides life support and living quarters for three crew members, as well as guidance, navigation, andorientationcontrol for the station. This is also where the station's power, propulsion, and life support systems are kept.It boasts three sections: living quarters, a service section, and a docking hub.

The ISS on the other hand is divided into two sections. There's theRussian Orbital Segment (ROS) that is operated by Russia, and the United States Orbital Segment (USOS) that is run by the United States, together with a number of other nations. Each has its own living quarters as well as science laboratories.

The ISS boasts very useful and efficient robotic arms and airlocks that are not present in the Chinese space station.

"Robotic arms are mounted outside the space station. The robot arms were used to help build the space station. Those arms also can move astronauts around when they go on spacewalks outside. Other arms operate science experiments," writes NASA in a statement.

"Astronauts can go on spacewalks throughairlocksthat open to the outside. Docking ports allow other spacecraft to connect to the space station. New crews and visitors arrivethrough the ports. Astronauts fly to the space station on the Russian Soyuz. Robotic spacecraft use the docking ports to deliver supplies."

Tiangong is fitted with the Chinese Docking Mechanism, based on the Russian Androgynous Peripheral Attach System(APAS-89/APAS-95) system. This isused by Shenzhou spacecraft and also in previous Tiangong prototypes.

There have been claims that Tiangong's docking system is a clone of the APAS system, which should make it compatible with the ISS's docking system. However, others argue that the two systems are not fully compatible.

The ISS's mission is to testspacecraft systems that will be required for long-duration missions to the Moon and Mars and Taingong's is quite similar. TheChina Manned Space Agency (CMSA), who operates the space station, has listed the new space station's purpose as:

"Further development of spacecraft rendezvous technology; Breakthrough in key technologies such as permanent human operations in orbit, long-term autonomous spaceflight of the space station, regenerative life support technology, and autonomous cargo and fuel supply technology; Test of next-generation orbit transportation vehicles; Scientific and practical applications at large-scale in orbit; Development of technology that can aid future deep space exploration."

The ISS has supported as many as 13 crew members onboard whereas the Taingong is currently equipped to handle three.

OK, it's not fair to compare the experiments of the two stations, considering the ISS has been around for over two decades, but it should be noted that Tiangong has an ambitious experimental schedule planned.The new space station will be equipped to hold more than 20 experimental racks with enclosed, pressurized environments, and more than 1,000 experiments have been tentatively approved by CMSA.

These include experiments in space life sciences and biotechnology, microgravity fluid physics and combustion, material science in space, and fundamental physics in microgravity, all areas that the ISS's experiments also explore.

In the end, the two space stations share more similarities than differences. They are both space stations after all. What will be interesting to see is if the Chinese space station slowly grows to be as big and as productive as the ISS. Its makers definitely have the ambition to make it so. Time will tell whether they reach this lofty goal.

Factories in Space? Yeah, That’s a Thing Now – Motley Fool

Posted: at 3:43 pm

It began with a 3D printer. It may end with factories in space.

In 2013, NASA announced it was collaborating with specialized 3D printing company Made in Space on a "Printing in Zero G Experiment" to see if 3D printers could print replacement machine parts, tools, and other equipment for use aboard the International Space Station (ISS).

One of the first items printed in space, says Made in Space, was a simple wrench -- needed to replace an astronaut's misplaced wrench. As it turned out, this was an ideal experiment for two reasons: First, because it demonstrated the advantages of being able to print a necessary item immediately and on-site, rather than being required to "phone home" to Houston and have a new wrench sent up by rocket.

And second, because of the potential cost savings. You see, getting anything physical from Earth to orbit -- be it a satellite or a computer or just a simple wrench -- costs a minimum of $5,000 per kilogram (2.2 pounds). But once it's possible to take raw materials collected "in space," and print them into new, finished items, the cost to orbit will shrink to the cost of emailing a set of instructions to the printer.

And there's a third advantage to manufacturing in space, too -- and it's a big one for investors.

Image source: Getty Images.

Turns out that one of the best reasons to manufacture things in space, is the fact that some things can only be manufactured in a zero-gravity environment -- which brings us to Varda Space Industries and Rocket Lab.

S&P Global Market Intelligence shows that Varda Space, which operates out of a Los Angeles suburb just a few miles south of SpaceX, has already attracted $51 million in start-up money from venture capital firms. The company says its mission is to build "the world's first commercial zero-gravity industrial park" in orbit. Only there, says the company, are the conditions right for manufacturing "more powerful fiber optic cables" and "new, life-saving pharmaceuticals" that can't be produced on Earth.

First, though, Varda needs to prove the concept. And for that, it turned to small rocket launcher and soon-to-be IPO Rocket Lab, currently known by its SPAC (special purpose acquisition company) name, Vector Acquisition Corp (NASDAQ:VACQ).

As the companies announced last week, Varda has hired Rocket Lab to produce for it three, or possibly four, Photon spacecraft to carry its Varda "space factories" into orbit. Weighing in at just 120 kilograms (265 pounds) each, "factory" is probably a generous term, but Varda says that's big enough to permit each factory to crank out 40 kilograms (88 pounds) to 60 kilograms (132 pounds) of finished goods over the course of three months in orbit. Crucially, these factories will also include "re-entry modules" to return the products manufactured in space to Earth -- which is the ultimate goal of putting factories in space, after all.

"But wait!" you object. Even if Varda's space factories are able to successfully turn raw materials into finished products in space, won't they need to bring the raw materials along with them in the first place?

And the answer to that question is "yes." Similar to how things work with 3D printing on the ISS, Varda is going to have to pay to launch both the space factories themselves, and also the raw materials they will work with. So in this first attempt, at least, we won't see any immediate solution to the high cost of moving mass from Earth to orbit.

That being said, Varda and Rocket Lab are still breaking new ground here, and blazing a trail toward the concept of putting factories in orbit. If they succeed, then the next logical step will be to begin hunting for raw materials already present in space (the moon being the most likely place to prospect). And with access to raw materials secured, Varda envisions a day when it might be building space factories as large as the ISS itself and manufacturing goods in zero gravity at scale.

At that point, it should be possible to cheaply manufacture unique products that can only be manufactured in space, and then deliver them down to Earth.

We're probably years, if not decades, away from seeing this become a reality. But once it happens, an entirely new space economy will be born, offering all sorts of new possibilities for investment. Varda's and Rocket Lab's mission will be one of the first baby steps toward making that happen -- and it will happen in Q1 2023.

Boeing Starliner back at factory to diagnose and fix the propulsion system valves – Florida Today

Posted: at 3:43 pm

Note: We've brought you a front-row seat to Florida rocket launchessince 1966. Journalism like our space coverage takes time and resources.Pleaseconsider a subscription.

Boeing's Starliner spacecraft returned to its factory at Kennedy Space Center this week but it wasn't the homecoming anybody hoped for.

Starliner, designed to fly astronauts to the International Space Station,was set to launch from Cape Canaveral Space Force Station on Aug. 3 for its second orbital flight test but problemswith the propulsion system valves halted the countdown.

Engineers discovered that 13 oxidizer valves were stuck in the closed position.The failed valves were on thrusters that control both orbital maneuvering as well as controlling the spacecraft during rendezvous and docking with the space station.

Over the next few days, the Boeing team was able to get nine of the valves to open but four of them remain stuck in the closed position.

John Vollmer, vice president and program manager of Boeings Commercial Crew Program, said that a moisture issueis most likely the cause of the problem

The moisture we saw on the valve is atmospheric moisture. It is not intrusion moisture," said on a call with reporters.

Now that Starliner is back at Boeing's factory, the team will resume deeper level troubleshooting.

Weve got to go back and look and see if there was some ambient moisture that was retained in there during the assembly of these valves or was there something that caused a leak of moisture to get in there? Vollmer said.

Boeing is working with their partners at Aerojet Rocketdyne, the company that manufacturesthe propulsion system, to solve the problem.

The second attempt of Starliners orbital flight test will not happen this month and Vollmer said it's too soon to project when or if it will launch this year.

Boeinghas been under enormous pressureto show its spacecraftis reliable after software issues hampered its first orbitalflight test in Dec. 2019.

NASA selected two providers, SpaceX and Boeing, to be launch providers capable of carrying astronauts to the space station to encourage competition and to end America's reliance on the Russian Soyuz spacecraft.

SpaceX is getting ready to send its fourth crewed mission to the space stationon Oct. 31 carrying NASA astronauts Raja Chari, Tom Marshburn and Kayla Barron and European Space Agency astronaut Matthias Maurer.

Sign up for the Morning Brief, delivered weekdays.

If youre in L.A., take a minute tonight to take a look at the night sky for a special surprise.

Starting at 8:25 p.m. the International Space Station will be visible with the naked eye no telescope needed.

The conditions today are prime for viewing with clear skies and no moonlight, according to the National Weather Service.

The station will be visible first coming from the northwest corner of the sky and move directly overhead to the southeast corner. It may not be immediately visible, but after a few minutes should appear as a small light dot moving across the sky.

While the ISS passes over L.A. regularly, it usually does so during daylight or low on the horizon, making it difficult to see.

There are currently seven people aboard the ISS, which is over 250 miles above the Earth.

Blobs in space and other cool science launching to the space station Tuesday – Space.com

Posted: at 12:37 pm

WALLOPS ISLAND, Va. Northrop Grumman's next Cygnus cargo ship will launch on a journey to the International Space Station tomorrow, carrying with it a bevy of research investigations and crew supplies for the astronauts of Expedition 65.

The keg-like spacecraft will launch from the Mid-Atlantic Regional Spaceport (MARS) at NASA's Wallops Flight Facility in Virginia on Tuesday (Aug. 10) at 5:56 p.m. EDT (2156 GMT) packed with more than 8,200 lbs. (3,700 kilograms) of crew supplies, research investigations and hardware including a new mounting bracket for the station's upgraded solar arrays.

After the capsule's two-day journey to the ISS, NASA astronaut Megan McArthur will use the space station's robotic arm to capture the Cygnus on Thursday (Aug. 12), and with the help of European Space Agency astronaut Thomas Pesquet, she will berth the vessel to the orbital outpost.

Prior to launch, Northrop Grumman announced that this Cygnus would be named the S.S. Ellison Onizuka, after the first Asian American astronaut, who lost his life aboard the space shuttle Challenger in 1986.

Cygnus is carrying a variety of cargo from crew supplies and hardware, to research investigations and even a new carbon dioxide removal system for the orbital outpost.

Also tucked inside the Cygnus capsule are several investigations to help researchers better understand how spaceflight affects the human body. One such experiment, called Cardinal Muscle, will look at how engineered muscle tissue forms in space to see if microgravity is a good research tool for understanding a type of age-related muscle loss called sarcopenia. As people age, they naturally become more sedentary and in turn, lose muscle mass. The same thing happens to astronauts in space, but at a much faster rate.

Ngan Huang, an assistant professor of cardiothoracic surgery at Stanford University in California is leading the investigation. She told Space.com that the experiment will involve muscle tissue grown on tissue chips. The researchers will engineer muscle tissue in microgravity, and study the affects of that environment on the tissue, in order to identify better therapies to use back on Earth.

The other part of the study is to validate this platform as a viable drug screening platform in microgravity. The researchers will test drugs that are known to have some ability to improve muscle formation on the engineered muscle tissue.

"We will use these drugs in space to see how well they work in microgravity as compared to on the ground," Huang said.

Redwire is sending a new printhead to the space station that could help astronauts build better habitats on the moon or Mars. The project is a technology demonstration that will use a regolith simulant to emulate the rocky soil on the moon as raw material for the 3D printer already on the space station.

Redwire's Chief Technology Officer Michael Snyder explained what the company hopes to achieve with the project, and what it could mean for future space exploration missions during a prelaunch science briefing.

"This experiment represents a critical step in developing sustainable manufacturing capabilities for lunar surfaces that will ultimately establish a permanent human presence off-earth by utilizing available resources with adaptive systems," he said during the news conference. "So this is really exciting for the future and hopefully, something like this gets eventually deployed to the moon."

Snyder said that the company will be printing three different specimens in space. The trio will then be returned to Earth on a later mission and analyzed for quality. Researchers on Earth have been 3D printing with regolith for years, but now it's time to see how the space-based samples will hold up on the ground.

"Once those components or specimens are returned, NASA will test the material properties of the prints by performing destructive tests," Synder said.

In a partnership with NASA, the European Space Agency (ESA) is sending a slime mold to space to test how it functions in microgravity in an experiment called Blob. Although it lacks a brain, the single-celled organism known as Physarum polycephalum (aka a slime mold) can move, feed itself and even communicate with other slime molds.

Researchers at the French National Center for Space Studies (CNES) decided it would be smart to send not one but four slime molds an organism that can double in size every day to the space station. What could go wrong, right? But don't worry, the blobs will travel to the space station in a dormant phase and will only going to be active for a few days. (If slime molds go without food for seven days, they return to a dormant state.)

Pesquet will be in charge of the slime mold. To kick off the investigation, he will wake up the slime mold, and use its activities to engage school children around Europe. Pesquet will be observing how the slime mold behaves in microgravity and the results will be compared to a terrestrial counterpart. The entire investigation will last for seven days, with Pesquet capturing both photos and video of the blobs in action.

Also packed inside the Cygnus capsule is a new carbon-dioxide scrubber to remove carbon dioxide from the atmosphere on the space station.

Called the four-bed carbon-dioxide scrubber, it's part of a technology demonstration that will attempt to improve upon the current system that's been onboard the ISS for nearly 20 years, but with some upgrades.

"We used data gathered over those 20 years to implement some design changes that will improve the liability and the longevity of the system," Michael Salopek of Johnson Space Center said during the same news conference.

The improvements being tested during this investigation are crucial for future exploration missions beyond low Earth orbit, the researchers said. Its main goal is to recycle and regenerate most of the air and water necessary to sustain the station's crew. To that end, the carbon dioxide scrubber will retain water vapor while filtering carbon dioxide out of the space stations airflow, much like the version currently on station.

That system works by removing water vapor and carbon dioxide from the atmosphere. The water vapor is cycled through the system and returned back to the cabin, while the carbon dioxide is either diverted to a reduction system, where it will be converted into water, or it is expelled from the spacecraft.

Researchers want a system that can operate continuously for 20,000 hours without a failure. To date, no life support system has met that goal, but the engineers believe the technology in this system will do so.

The new upgrades being tested will also help prevent long-term dust accumulation and erosion, which can jam valves and other moving parts inside the system.

This tech demo will eventually replace the current system on the ISS if all goes according to plan. Initially, it will be tested for one year. Samples collected from the carbon dioxide absorption beds will be sent back to Earth for researchers at Johnson Space Center to analyze to ensure that the system is working properly in order to maintain astronaut health. The hardware will then remain on the orbiting laboratory for three additional years of testing.

Cygnus will remain attached to the space station until October. When its mission ends, it will detach and complete its secondary mission called Kentucky Re-Entry Probe Experiment (KREPE), which will test new thermal protection systems.

Thermal protection systems (or TPS) are a crucial part of a spacecraft, protecting the vehicle as it travels through the atmosphere. Cygnus is carrying three different capsules, each of which is outfitted with sensors to study how different materials hold up to the searing heat of re-entry.

Unlike SpaceX's cargo Dragon capsule, the Cygnus is designed to burn up during re-entry, and is predominately used as a waste disposal means after it delivers its cargo to the space station. To that end, researchers decided that on this flight they will test out new thermal protection materials as the spacecraft meets its fiery end.

Each of the capsules are designed to withstand the spacecraft breaking apart and will ultimately splashdown somewhere in the ocean. Researchers said during a news conference that the capsules will not be recovered, but their data will be logged and used to make spacecraft safer as well as help with fire safety systems here on Earth.

The International Space Station Had a Rough Day – The Atlantic

Posted: August 2, 2021 at 1:44 am

Mission control in Houston first noticed it Thursday morning.

The International Space Station was drifting. The station is always moving, of course, in a looping trajectory around Earth. But this, what mission control was seeing in the latest data, was unexpected, and unnerving. On Thursday morning, the space station was suddenly and mysteriously deviating from its course.

The massive pieces of NASA-built hardware that hold the space station in place couldnt keep up with the motion, and within minutes, the station had been thrown out of its usual orientation.

NASA quickly turned to Roscosmos, Russias space agency. To counter the shift, Moscows mission control commanded one of its modules on the space station to ignite its engines, then instructed a cargo ship to fire its thrusters too. Inside the station, astronauts reconfigured important systems. Twice, ground control lost communications with the crew for several minutes. The longer the space station remained off track, the more scrambled its operations, including the communication system and solar panels, could become.

It took about an hour to drag the ISS back into its proper configuration, and regain what its operators call attitude control. The source of the disruption was another Russian module, which had just arrived at the station. The module, a laboratory named Nauka, the Russian word for science, had already had a rough journey, punctuated by propulsion and communications issues, with Russian engineers rushing to put it in the right orbit. Several hours after it docked, the module, reacting to a software glitch, started firing its thrusters uncontrollably, jostling the space station. When Nauka went rogue, and Moscow instructed hardware on the other side of the station to respond, the ISS found itself in what a NASA mission-control operator called a tug of war.

Seven astronauts were on board at the timethree American, two Russian, one French, and one Japanese. NASA later told reporters that the astronauts hadnt felt any shaking or movement, and officials tried to assure the public that the crew was safe. There was no immediate danger at any time to the crew, Joel Montalbano, the ISS program manager at NASA, said in a press conference. Obviously, when you have a loss of attitude control, thats something you want to address right away, but the crew was never in any immediate emergency or anything like that.

Montalbano and other NASA officials stressed that the agencys workers are prepared for all kinds of emergencies, and that they werent worried, because they hadnt exhausted their contingency plans. But this shake-up was an uncommon event; the station has experienced inadvertent thruster firings, such as Naukas, maybe only three or four times in its 20-year history. And even if theyre resolved quickly, without real incident, theyre inevitably unsettling. In my experience, people in space are always in danger, tweeted Wayne Hale, a former flight director and manager at NASAs space-shuttle program, which experienced two fatal accidents that claimed the lives of a total of 14 people.

The Nauka scare called to mind an incident that occured in 2018, when mission controllers noticed that the space stations air pressure had started dropping slightly, a sign of a tiny leak. In that case, the crew was asleep. Officials decided that the pressure change was small enough that it didnt warrant waking the astronauts. In the morning, the crew scoured the station and found a tiny hole in a Soyuz capsule, a Russian astronaut vehicle. Officials said the crew was never in serious danger, but no one wants a leak of any kind on the ISS, and the hole was quickly plugged up. Russian cosmonauts eventually conducted a spacewalk to examine the hole from the exterior, but to this day, Roscosmos wont say how it got there.

So many aspects of spaceflight are autonomous now, including the cargo ships that dock to the ISS and the capsule that recently took Jeff Bezos to the edge of space and back. Blue Origin passengers dont have to fly the capsule as astronauts have in the past. Neither do SpaceX passengers, who go well beyond the edge of space and all the way into orbit; last year, when two NASA astronauts test-drove a SpaceX capsule to the ISS, they flew on autopilot, taking control of the vehicle for only a few minutes, just to see how it handled. (At the time, Russian officials were the ones worried that SpaceXs new flight software could malfunction and shove the capsule at the station.) But even today, spaceflight is far from routine, and not as smooth as recent feats have made it seem. Yes, two billionaires have flown to space in less than a month, and yes, they made it look easy. But space travel, by professional astronauts and tourists alike, remains dangerous. The futures that Bezos and Elon Musk sometimes imagineof human beings living in artificial-gravity stations around Earth, or in an outpost on the moon, or in a glass dome on Marsare fragile in that way.

The ISS is one of the most impressive engineering feats in history, assembled in orbit piece by piece by astronauts with the nerve to handle a tool kit while floating in space. The station was not meant to last forever, and someday, after some difficult decisions by the agencies that run it, it will be deemed too expensive or too old, and, like other stations before it, will likely be retired into the depths of Earths oceans. In its two decades, the ISS has served as more than a workplace or a laboratory for its rotating crews of spacefarers. It is also a home; astronauts share cleaning chores, celebrate holidays together, even binge-watch TV shows like the rest of us. I imagine that, after a few months of ISS life, astronauts are so used to floating that they drift off to sleep as easily as they would in bed on Earth. But in an instantin the sudden rogue firing of a moduleastronauts can be jolted back to the reality of what the ISS is, a metal tube traveling at 17,500 miles an hour, far beyond the reach of Earths protective, life-giving atmosphere. Future space travelers, whether they journey to the edge of space or another world, cant lose sight of that, no matter how lovely the view outside the window is.
