New submitter catmar68 writes: CERN proposes "space elevator" accelerator to answer this fundamental question: "Do antimatter apples fall up?" From the press release: The true question, they say, is whether antimatter apples fall down differently. If a difference were spotted, it would spell the end of "CPT invariance" -- a principle that has underpinned every theory of physics since the invention of quantum mechanics. "The Standard Model of particle physics has been very successful, but it can't explain the 95% of the universe which is 'dark', and neither Einstein nor any physicist since has been able to cook up a working theory of quantum gravity," says theorist Flora Oilp. "It's time to challenge its most fundamental principle head-on." The way forward, according to Oilp and her colleagues, is to build a vertical accelerator that will put gravity to the test directly. Every previous particle accelerator has been horizontal. A combination of high speeds and frequent course corrections using focusing magnets has always meant that the effect of gravity can be neglected. But by utilising a range of new, revolutionary techniques, including accelerating particles upwards inside a vacuum vessel, and timing how long they take to fall back down to Earth, physicists can study the elusive fourth force directly. Furthermore, by comparing results with protons and antiprotons, they can watch for signs of "CPT violation." Such behaviour cannot be explained using conventional theories, which rely on this principle to ensure the conservation of probability.

The accelerator would be built in two stages. Stage one proposes a 500 m vertical accelerator, starting from the base of the LHC shafts. An exciting collaboration with NASA may come to fruition by utilising detectors on the International Space Station (ISS) to detect beams of particles fired by the accelerator every time the ISS is overhead. This "reverse cosmic-ray" experiment would allow the measurement of Earth's gravity on particle trajectories at unprecedented levels. Stage one will seek to match the roughly 1% precision on measurements of the gravitational constant "g," which is currently being targeted in parallel by experiments with antihydrogen at the Laboratory's Antimatter Factory. This moderate build will also allow engineers and physicists to understand the intricacies of running a vertical accelerator in preparation for stage two -- the space elevator. "If built, however, this advanced particle accelerator would nevertheless be three times taller than the Burj Khalifa in Dubai, which has been the tallest structure in the world since 2009."

PolygamousRanchKid shares a report from Motherboard: In November 2019, twelve bottles of Chateau Petrus 2000 -- a rare and expensive red wine from Bordeaux, France -- hitched a ride to the International Space Station aboard a Northrop Grumman spacecraft. It was followed several months later by 320 snippets of grapevine, or canes, of Merlot and Cabernet Sauvignon. For a year, both viticultural products were exposed to the unique stress of the station's microgravity environment. On January 1st, the wine bottles and canes returned to earth aboard a SpaceX cargo vessel, and were hurried back to the Institute of Vine and Wine Science (ISVV) at the University of Bordeaux. Researchers have already begun analyzing the changes they underwent while in orbit, and during a press conference on Wednesday, revealed their preliminary findings. They had also, of course, tasted the wine.

To the surprise of researchers, all 320 vine snippets survived the stay in space. Some have since been replanted, and the results have been astounding. "They are developing much, much faster than the normal canes -- the ones that are coming back from space," said Dr. Michel Lebert, SCU's Chief Science Officer. The wine, to the delight of the experiment's organizers, also appears to have undergone significant changes. "With the one that had been in space, I would say the differences that I found most were with heightened floral characteristics," said Jane Ansen, a wine writer with a diploma in wine-tasting from ISVV. "I would probably say that the Petrus 2000 that had been on the ISS was maybe one, two, even three years further evolved that you would expect compared to the one that had remained on earth,"; she said.

"When the Earth environment is recreated in space, like on the ISS, the only parameter that changes from Earth is near-zero gravity," said Nicolas Gaume, CEO of Space Cargo Unlimited. "This exposes life on the ISS to immense stress." The researchers hypothesize that this stress, promoted by microgravity, expedited the natural aging process taking place in the wine bottles, and led the canes to develop a resiliency that is contributing to their rapid growth back on earth. If their theory is correct, the implications could be significant for a future in which climate change threatens to disrupt agricultural production. "If the vines find a way to evolve so that they are more naturally resistant to stress on Earth, then that opens very exciting possibilities for all of us," said Gaume.

"A pallet of batteries was released from the International Space Station last week, becoming the heaviest single piece of junk ever jettisoned from the station," reports UPI: Mission controllers in Houston commanded the Canadarm2 robotic arm to release an external pallet loaded with the 2.9 tons of nickel-hydrogen batteries into Earth's orbit Thursday morning. "It is safely moving away from the station and will orbit Earth between two to four years before burning up harmlessly in the atmosphere," NASA said in a statement.
Gizmodo shares a photo of the pallet orbiting 265 miles (427 km) above Chile. And they add that this chain of events starte in 2011 when NASA decided to switch the Space Station from nickel-hydrogen batteries to lithium-ion batteries. This effort required four supply missions from the Japanese H-II Transfer Vehicle (HTV) cargo spacecraft, 13 different astronauts, and 14 spacewalks, in which 48 nickel-hydrogen batteries were replaced by 24 lithium-ion batteries...

"It used to be that it wasn't a big deal to toss stuff from ISS because very few satellites were below it [at altitudes below 250 miles (400 km)], " Jonathan McDowell, an astrophysicist at the Harvard-Smithsonian Center for Astrophysics, explained in an email. "That's not so true any more with a bunch of cubesats and with recently launched Starlinks during orbit raising. So I have concerns."

To which he added: "I don't immediately see what else they could have done except fly a whole extra HTV mission just to get rid of it."

According to the European Space Agency, around 34,000 objects larger than 3.9 inches (10 cm) are currently in orbit around Earth, in addition to millions of tinier objects, such as tools and bits of spacecraft. The volume of objects in space, both functional and non-functional, is steadily increasing, prompting concerns of potential collisions and even more orbital debris.
A NASA representative told Gizmodo their ballistics officers "indicate no threat" of the pallet smashing into other space objects, but added "this item, like all, will be tracked by U.S. Space Command."

AmiMoJo shares a report from ScienceAlert: The menagerie of bacterial and fungal species living among us is ever growing -- and this is no exception in low-gravity environments, such as the International Space Station (ISS). Researchers from the United States and India working with NASA have now discovered four strains of bacteria living in different places in the ISS -- three of which were, until now, completely unknown to science.

Three of the four strains were isolated back in 2015 and 2016 -- one was found on an overhead panel of the ISS research stations, the second was found in the Cupola, the third was found on the surface of the dining table; the fourth was found in an old HEPA filter returned to Earth in 2011. All four of the strains belong to a family of bacteria found in soil and freshwater; they are involved in nitrogen fixation, plant growth, and can help stop plant pathogens. Basically, good bacteria to have around if you're growing things. The research has been published in Frontiers in Microbiology.

Microsoft will connect its cloud computing Azure Space platform to the Spaceborne Computer-2, a Hewlett-Packard Enterprise product promising to "deliver edge computing and [artificial intelligence] capabilities to the International Space Station (ISS)." Space.com reports: Spaceborne Computer-2 will launch to space Feb. 20 aboard a Northrop Grumman Cygnus cargo craft that will also deliver tons of other supplies, experiments and food for the station's Expedition 64 astronauts. An Antares rocket will launch the Cygnus NG-15 cargo mission from NASA's Wallops Flight Facility on Wallops Island, Virginia. Spaceborne Computer-2's mission could last two or three years. Once the computer is up and running in orbit, researchers will be able to use the Azure cloud system to do intensive processing or to transmit results back to the device. The computer is based on HPE's Edgeline Converged Edge system designed to operate in harsh environments.

Growing plants in space, modeling dust storms on Earth to assist with Mars mission planning, and doing ultrasound medical imaging for astronaut health care are some of the many fields that the collaboration will address, the companies said in a press release. "The combined advancements of Spaceborne Computer-2 will enable astronauts to eliminate longer latency and wait times associated with sending data to-and-from Earth, to tackle research, and gain insights immediately for a range of projects," the release added.

The new project builds on the lessons learned from a predecessor proof-of-concept device, called Spaceborne Computer. This flew to the space station for a one-year mission in 2017 to investigate computer reliability in space, amid a harsh environment that includes high radiation and zero gravity. "The goal was to test if affordable, commercial off-the-shelf servers used on earth, but equipped with purposefully-designed software-based hardening features, can withstand the shake, rattle and roll of a rocket launch to space, and once there, seamlessly operate on the ISS," the press release said, adding the predecessor mission was a success. "Additionally, gaining more reliable computing on the ISS is just the first step in NASA's goals for supporting human space travel to the moon, Mars and beyond where reliable communications is a mission critical need," the release noted.

Astronauts Mike Hopkins and Victor Glover floated back outside the International Space Station Monday and completed solar array battery replacement work that began four years ago. They also installed three new video cameras and made preparations for upcoming work to install new roll-out solar blankets to upgrade the lab's power system. From a report: The work took less time than expected and the astronauts were able to carry out a variety of lower-priority "get-ahead" tasks before returning to Quest airlock and calling it a day, closing out a five-hour 20-minute spacewalk. Taking one last look around before entering the airlock, Hopkins said simply, "Beautiful view." The excursion began at 7:56 a.m. EST when the two men switched their spacesuits to battery power, officially kicking off the 234th spacewalk, or EVA, devoted to station assembly and maintenance since construction began 23 years ago in 1998.

"OK, it's a beautiful day. Let's go for a walk outside," astronaut Bob Hines radioed from mission control in Houston. The first priority was electrically connecting a replacement battery in the station's solar power system. The batteries are critical to station operation. They are recharged by the arrays when the lab is in sunlight and then provide that stored power during periods of orbital darkness. Starting in 2017, spacewalking astronauts began work to replace all 48 of the station's original nickel-hydrogen batteries with 24 smaller, more powerful lithium ion units. During battery replacement work in March 2019, one of the new lithium ion power packs used by the station's left-side inboard set of arrays failed and was replaced with one of the older nickel hydrogen batteries that had been removed. All of the other older batteries were replaced as planned during multiple spacewalks. Over the weekend, flight controllers operating the station's robot arm by remote control disconnected the one remaining nickel hydrogen battery and robotically installed a fresh lithium ion unit. Hopkins and Glover electrically connected the battery, finally completing the power system upgrade four years after the work began.

An American real estate investor, a Canadian investor, and a former Israeli Air Force pilot are paying $55 million each to be part of the first fully private astronaut crew to journey to the International Space Station. The Verge reports: The trio will hitch a ride on SpaceX's Crew Dragon capsule early next year, with a veteran NASA astronaut as the commander. The Ax-1 mission, arranged by Houston, Texas-based space tourism company Axiom Space, is a watershed moment for the space industry as companies race to make space travel more accessible to private customers instead of governments. Private citizens have trekked to the space station in the past, but the Ax-1 mission marks the first to use a commercially built astronaut capsule: SpaceX's Crew Dragon, which flew its first two crews to the ISS last year.

Larry Connor, an entrepreneur and nonprofit activist investor; Mark Pathy, the Canadian investor and philanthropist; and Eytan Stibbe, the former Israeli fighter pilot and an impact investor, were revealed by Axiom on Tuesday morning as the company's inaugural crew. Connor, 71, is president of The Connor Group, a luxury real estate investment firm based in Ohio. He'd become the second-oldest person to fly to space after John Glenn, who flew the US space shuttle Discovery at 77 years old.

The crew's flight to the space station, an orbital laboratory some 250 miles above Earth, will take two days. They'll then spend about eight days aboard the station's US segment, where they'll take part "in research and philanthropic projects," Axiom said in a statement. Living alongside working astronauts from the US, Russia, and likely Germany, the private crew members will roll out sleeping bags somewhere on the station. [...] The Ax-1 mission will have to be approved by the Multilateral Crew Operations Panel, the space station's managing body of partner countries that includes the US, Russia, Canada, Japan, and others. That approval process kicked off today...

Boeing's test of the largest rocket in U.S. history ended earlier than expected on Jan. 16 because a hydraulic-system setting exceeded a preset limit, dealing another setback to the company's space ambitions. From a report: The first firing of all four RS-25 engines on the Space Launch System rocket ended just 67.2 seconds into the planned eight-minute test. The so-called hot fire exercise at the NASA's Stennis Space Center in Mississippi was designed to simulate a full flight from Earth. Engineers from NASA, Boeing and the engines' maker, Aerojet-Rocketdyne Holdings, will assess data and determine whether a second test is needed or if the rocket is ready to ship to Florida's Kennedy Space Center to prepare for its maiden flight. The SLS can be loaded with its super-chilled propellants -- liquid oxygen and liquid hydrogen -- only nine times, which will be a consideration in whether to stage a second test at Stennis, NASA said Tuesday.

The shutdown "was triggered by test parameters that were intentionally conservative to ensure the safety of the core stage during the test," NASA said in a blog post Tuesday. Preliminary inspections and data reviews "show the rocket's hardware is in excellent condition," the agency said. The test was cut short just as the engines began to pivot and test their thrust capability while rotating on gimbals. The premature end, before engineers collected a full array of data, represented another hurdle for Boeing's space program. The SLS rocket has been plagued by years of delays and billions of dollars in cost overruns. The program has broad support in Congress because of the federal contracts and jobs it offers across many states. Boeing also is attempting to correct glitches with its Starliner spacecraft, which would ferry astronauts to and from the International Space Station under a NASA contract. Boeing said Monday it had completed qualification of Starliner's flight software following an extensive review. A second test of the vehicle to the ISS is slated for March, following a botched flight in December 2019. A crewed flight is expected later this year.

"Axiom Space has announced that it is creating an office park and manufacturing center at the Houston SpacePort at Ellington Field," notes an opinion piece for The Hill by Houston-based space writer Mark R. Whittington.

"The development is a hopeful sign that, despite foot dragging by Congress, a commercial replacement for the International Space Station may well happen." The United States has a chance to avoid a "space gap" when the ISS reaches the end of its operational life, like the one that happened between the end of the space shuttle program and the first launch of the SpaceX commercial crew Dragon mission. When Jim Bridenstine became NASA administrator, one of the questions confronting him was what to do about maintaining a presence in low Earth orbit after the ISS. The idea that he and experts at NASA have been pushing is to encourage private companies to build their own space station.

NASA would provide needed support by pledging to become an anchor tenant for such orbiting facilities. However, the commercial space stations would also have to find private customers. The problem is that Congress has been remarkably stingy when it comes to putting up real money for this approach. The fiscal 2020 budget request included $150 million for commercial space stations. Congress funded support for private orbiting labs for a grand total of $15 million...

Axiom Space has won the nod to attach one of its own modules to the ISS. Not waiting for Congress to cough up funding for NASA, Axiom has announced a facility to manufacture space station modules at the Ellington SpacePort in Houston. The company will also have private astronaut training facilities. Besides employing 1,000 people, the new Axiom facility represents a commitment to creating a commercial space station industry... It is also likely no accident that the Axiom facility is about a five-hour drive from the growing SpaceX spaceport in Boca Chica near the southern tip of Texas. No doubt SpaceX CEO Elon Musk would be pleased to launch finished modules to space, using the mighty Starship rocket, and later crews and cargo.

In the midst of a pandemic, part of a space future is taking shape in South Texas. This time it's being driven by the private sector. NASA had best jump on board or risk being left behind.

Since 1955 the U.S./Canadian operation that monitors North American airspace with radars and satellite to maintain air sovereignty has also, at Christmas time, been tracking Santa.

And this year their trackers received additional support from the U.S. Space Command, a joint-military command drawing its units from five military service branches (including the U.S. Space Force). That command "launched a new reindeer tracker to pinpoint the exact location of Santa's sleigh at any given time during the night," according to NPR's Morning Edition, with General James Dickinson telling them the equipment's official name: Rudolph Infrared Tracking System. "We made some upgrades this year."

And that was just the beginning, reports The Hill: Santa knows astronauts need presents, too, and made his first known visit to the International Space Station to deliver them this year.

The North American Aerospace Defense Command (NORAD), which tracks Santa's Christmas Eve journey every year, depicted in a tweet Santa arriving at the International Space Station on Christmas Eve...

The Federal Aviation Administration cleared Santa for the flight to space on Wednesday, providing him "for the first time ever" with a special commercial space license.
The astronauts aboard the ISS recorded a special Christmas video this year. (And a new article in Business Insider expores how astronauts on the space station have celebrated Christmas over the years.)

And NORAD is even maintaining a special web site at NORADSanta.org which not only let visitors track Santa, but through December 31st will also offer an arcade with Christmas-themed videogames, a selection of music by the U.S. Air Force Academy Band, and even a gift shop where you can buy "Santa and NORAD gear," including NORAD hoodies and tote bags.

Though a pop-up window warns visitors that "Clicking through to this next website does not constitute an official endorsement or approval by the United States Department of Defense or NORAD of any product or service."

During the Great Conjunction event in which Jupiter and Saturn appeared closer to each other in the sky than they have for hundreds of years, photographer Jason De Freitas captured a photo showing the ISS zipping between the two planets. PetaPixel reports: While planning to photograph the conjunction of Jupiter and Saturn, De Freitas realized that he could also include the ISS in the frame. "I had the incredible luck of figuring out I could see the path of the International Space Station traveling through the Jupiter-Saturn conjunction," De Freitas says. After a great deal of planning, on December 17th, De Freitas drove an hour -- "quite a short distance in the scheme of things," he says -- to a location where everything would be aligned perfectly for his shot.

At around 9:54pm from Jellore Lookout in New South Wales, Australia, De Freitas pointed his Pentax 67 and Takumar 600mm f/4 at the planets and captured a 10-second exposure on Fujifilm Provia 100f film. The tracking was done with a Skywatcher NEQ6 equatorial mount. The photo above is what resulted. Here's a closer crop in which you can more clearly see the planets and Jupiter's moons. De Freitas also used a Nikon D750 and Tamron 70-200mm f/2.8 to capture digital video of the event. "Probably the most unique shot I've ever taken," De Freitas says. "[S]omehow everything on the night worked out. Beyond thrilled with this one.

Four astronauts aboard their SpaceX Dragon capsule "Resilience" have arrived at the International Space Station, circling 262 miles above the Earth, where they will stay until spring. From a report: The capsule lifted off from the Kennedy Space Center Sunday evening atop a SpaceX Falcon 9 rocket, chasing the ISS for 27 hours before matching its altitude and speed for an orbital dock. The flight marks only the second crewed flight for Crew Dragon, which became the first commercial vehicle to put humans in orbit when astronauts Doug Hurley and Bob Behnken launched in May. "SpaceX, this is Resilience. Excellent job, right down the center," commander Hopkins radioed to mission control after the docking. "SpaceX and NASA, congratulations." The flight marks another milestone for SpaceX flying its first fully operational mission. After the May launch, designated "Demo-2" with Hurley and Behnken, NASA certified the capsule for operational use in its Commercial Crew program. The Resilience crew includes three NASA astronauts and one from the Japan Aerospace Exploration Agency who were mostly passengers during the flight of Crew Dragon, which generally flies without human input and docks to the ISS autonomously.

Axiom Space has signed three private astronauts to join former NASA astronaut Michael Lopez-AlegrÃa on Ax-1, the first private mission into orbit and to the International Space Station. From a report: In March, Axiom Space announced plans to launch "history's first fully private human spaceflight mission to the International Space Station." The mission, dubbed Ax-1, would go forward using SpaceX's Crew Dragon vehicle to deliver private astronauts to the ISS for at least eight days. At the International Astronautical Congress last month, Axiom CEO Michael Suffredini said the company was aiming to launch in the fourth quarter of 2021. Details are still sparse. We know that former NASA astronaut Michael Lopez-AlegrÃa will be part of the mission, but the three other astronauts have not been announced yet. The promotional image Axiom posted Wednesday features three male silhouettes, suggesting there will be no female astronauts on board. There is some excitable chatter on Twitter and other places suggesting that two of the other astronauts might be actor Tom Cruise and director Doug Liman, who have been in talks with NASA about filming a movie on the ISS. NASA administrator Jim Bridenstine mentioned in June that Axiom was involved in those talks.

Since 2000, there have always been humans living and working on the International Space Station -- and the streak could just be getting started. National Geographic reports: On Halloween in the year 2000, a Russian Soyuz rocket launched from the Baikonur Cosmodrome in Kazakhstan and flew into the history books, carrying one U.S. astronaut and two Russian cosmonauts to the nascent International Space Station (ISS). The crew arrived two days later, and the space station has been continuously occupied by humans ever since, a 20-year streak of living and working in low-Earth orbit. "There's kids now who are in college who, for their entire lives, we've been living off the planet," says Kenny Todd, NASA's deputy program manager for the ISS. "When I was a kid, that was all stuff that was just dreams."

The orbiting laboratory is among the most expensive and technologically complex objects ever built: a $150-billion pressurized habitat as long as a football field, whizzing 254 miles above Earth's surface at 17,000 miles an hour. Over the decades, 241 women and men from around the world have temporarily called the space station home, some for nearly a full year at a time. "It's pretty crazy -- I'm surprised we haven't, like, really seriously hurt anybody," says retired NASA astronaut Scott Kelly, who spent nearly a year on one ISS stay. "It's really a testament to the seriousness [with which] people on the ground take this job, the attention to detail."

Upward of a hundred thousand people have worked together to design, build, launch, and operate the sprawling station, says David Nixon, who worked with NASA on ISS designs in the mid-1980s. "When you compare the station to the procession of great structures and buildings built by humanity since the dawn of civilization, it's up there with the Pyramids, the Acropolis -- all the great structures and edifices," he says. The future of the ISS remains uncertain. "The station is currently slated to run until at least 2024, and much of its hardware is certified to operate safely until at least 2028, if not longer for its younger components," the report notes.

"Will the ISS be disassembled and scavenged in orbit to construct a future space station? Will it be turned over to private companies as nations venture farther into space? Will the whole structure go out in a final blaze of glory, steered into a Pacific crash landing like the Russian space station Mir?"

"TCP/IP doesn't work at interplanetary distances," 77-year-old Vinton Cerf tells Quanta magazine. "So we designed a set of protocols that do." Specifically, bundle protocols: a disruption/delay-tolerant networking (DTN) protocol with nodes that can also store information: A data packet traveling from Earth to Jupiter might, for example, go through a relay on Mars, Cerf explained. However, when the packet arrives at the relay, some 40 million miles into the 400-million-mile journey, Mars may not be oriented properly to send the packet on to Jupiter. "Why throw the information away, instead of hanging on to it until Jupiter shows up?" Cerf said. This store-and-forward feature allows bundles to navigate toward their destinations one hop at a time, despite large disruptions and delays...

So, a couple decades after conceiving of bundle protocols, is the interplanetary internet up and running?

We don't have to build the whole thing and then hope somebody uses it. We sought to get standards in place, as we have for the internet; offer those standards freely; and then achieve interoperability so that the various spacefaring nations could help each other. We're taking the next obvious step for multi-mission infrastructure: designing the capability for an interplanetary backbone network. You build what's needed for the next mission. As spacecraft get built and deployed, they carry the standard protocols that become part of the interplanetary backbone. Then, when they finish their primary scientific mission, they get repurposed as nodes in the backbone network. We accrete an interplanetary backbone over time.

In 2004, the Mars rovers were supposed to transmit data back to Earth directly through the deep space network — three big 70-meter antennas in Australia, Spain and California. However, the channel's available data rate was 28 kilobits per second, which isn't much. When they turned the radios on, they overheated. They had to back off, which meant less data would come back. That made the scientists grumpy. One of the JPL engineers used prototype software — this is so cool! — to reprogram the rovers and orbiters from hundreds of millions of miles away. We built a small store-and-forward interplanetary internet with essentially three nodes: the rovers on the surface of Mars, the orbiters and the deep space network on Earth. That's been running ever since.

We've been refining the design of those protocols, implementing and testing them. The latest protocols are running back-and-forth relays between Earth and the International Space Station... We did another test at the ISS where the astronauts were controlling a little robot vehicle in Germany.

NASA's first new space potty in decades -- a $23 million titanium toilet better suited for women -- is getting a not-so-dry run at the International Space Station before eventually flying to the moon. The Associated Press reports: Barely 100 pounds (45 kilograms) and just 28 inches (71 centimeters) tall, the new toilet is roughly half as big as the two Russian-built ones at the space station. It's more camper-size to fit into the NASA Orion capsules that will carry astronauts to the moon in a few years. Station residents will test it out for a few months. If the shakedown goes well, the toilet will be open for regular business. The old toilets cater more toward men. To better accommodate women, NASA tilted the seat on the new toilet and made it taller. The new shape should help astronauts position themselves better for No. 2, said Johnson Space Center's Melissa McKinley, the project manager. "Cleaning up a mess is a big deal. We don't want any misses or escapes," she said.

As for No. 1, the funnels also have been redesigned. Women can use the elongated and scooped-out funnels to urinate while sitting on the commode to poop at the same time, McKinley said. Until now, it's been one or the other for female astronauts, she noted. Like earlier space commodes, air suction, rather than water and gravity, removes the waste. Urine collected by the new toilet will be routed into NASA's long-standing recycling system to produce water for drinking and cooking. Titanium and other tough alloys were chosen for the new toilet to withstand all the acid in the urine pretreatment.

First, PetaPixel reminds us that Estee Lauder's products will be launching into space this week: The cosmetics giant Estee Lauder is paying NASA $128,000 for a product photography shoot onboard the International Space Station. Bloomberg reports that the company will be paying the space agency to fly 10 bottles of its Advanced Night Repair skin serum to the orbiting space station on a cargo run that will launch from Virginia on Tuesday and dock on Saturday. Once the product is on board, astronauts will be tasked with shooting product photos of the serum floating in the cupola module, which has sweeping panoramic views of Earth and space.

NASA charges a "professional fee" of $17,500 per hour for the astronauts' time.
In a possibly-related story, the same flight will also be carrying a new $23 million space toilet to the station as part of a routine resupply mission "to test it out before it's used on future missions to the moon or Mars."

With space junk piling up around our planet, the International Space Station needed to perform a last-minute avoidance maneuver Tuesday to steer clear of an "unknown piece of space debris expected to pass within several kilometers." From a report: Mission Control in Houston conducted the move at 2:19 p.m. PT using the Russian Progress resupply spacecraft docked to the ISS to help nudge the station out of harm's way. "Out of an abundance of caution, the Expedition 63 crew will relocate to their Soyuz spacecraft until the debris has passed by the station," NASA said in a statement prior to the move. The maneuver went off smoothly, NASA administrator Jim Bridenstine reported. "The astronauts are coming out of safe haven," he tweeted after the ISS relocated.

CNN reports: A planned reality show will seek to give the winner of its on-air competition "the greatest prize ever given out on Earth" — a 10-day stay on the International Space Station...

The production company's press release said that the team is "now looking for global brand and primary distribution partners." Space Hero is planning to open the application process for the show in the first half of 2021 before broadcasting begins in 2022, a spokesperson said via email Friday... Space Hero, which is headed by a former News Corp executive named Marty Pompadur, said it is working with Texas-based startup Axiom Space to coordinate the trip into orbit.

Axiom was co-founded and led by Michael Suffredini, who led NASA's International Space Station Program from 2005 to 2015. The company plans to serve as a go-between for NASA, launch providers such as SpaceX and Boeing, and any private-sector individuals interested in booking rides to space for tourism, entertainment or other business purposes. Axiom has also said it can provide all the training necessary to prepare individuals for a trip to the ISS...

Private citizens have visited the space station before: A company called Space Adventures previously organized eight trips to the International Space Station for ultra-wealthy travelers between 2001 and 2009 using Russian Soyuz spacecraft. Allowing tourists and other private citizens to make use of the space station — via SpaceX's or Boeing's new spacecraft — is part of NASA's goal of commercializing outer space.
CNN notes that Axiom is also handling the training and coordination for that Tom Cruise movie that's going to be filmed in space.

NASA is preparing to oversee the largest push of business activity aboard the ISS. "Later this month, up to 10 bottles of a new Estee Lauder (EL) skincare serum will launch to the space station," reports CNN. "NASA astronauts are expected to film the items in the microgravity environment of the ISS and the company will be able to use that footage in ad campaigns or other promotional material." The details of those plans were first reported by New Scientist magazine. From the report: The Estee Lauder partnership will continue NASA's years-long push to encourage private-sector spending on space projects as the space agency looks to stretch its budget beyond the ISS and focus on taking astronauts back into deep space. Those efforts include allowing the space station to be used for marketing and entertainment purposes. The Estee Lauder products, a new formula of the company's "Advanced Night Repair" skin serum, are expected to launch aboard a Northrop Grumman Cygnus spacecraft, tucked alongside 8,000 pounds of other cargo, experiments and supplies. NASA astronauts will be tasked with capturing "imagery and video" of the product. The astronauts themselves, however, won't be appearing in any cosmetics ads: The space agency's ethics policies strictly bar astronauts from appearing in marketing campaigns.
