As Voyager 2 moves farther and farther from the Sun, the density of space is increasing. "It's not the first time this density increase has been detected," notes SciencAlert. "Voyager 1, which entered interstellar space in 2012, detected a similar density gradient at a separate location." From the report: Voyager 2's new data show that not only was Voyager 1's detection legit, but that the increase in density may be a large-scale feature of the very local interstellar medium (VLIM). The Solar System's edge can be defined by a few different boundaries, but the one crossed by the Voyager probes is known as the heliopause, and it's defined by the solar wind.
[...]
One theory is that the interstellar magnetic field lines become stronger as they drape over the heliopause. This could generate an electromagnetic ion cyclotron instability that depletes the plasma from the draping region. Voyager 2 did detect a stronger magnetic field than expected when it crossed the heliopause. Another theory is that material blown by the interstellar wind should slow as it reaches the heliopause, causing a sort of traffic jam. This has possibly been detected by outer Solar System probe New Horizons, which in 2018 picked up the faint ultraviolet glow resulting from a buildup of neutral hydrogen at the heliopause. It's also possible that both explanations play a role. Future measurements taken by both Voyager probes as they continue their journey out into interstellar space could help figure it out. But that might be a long bet to take. The findings have been published in The Astrophysical Journal Letters.

AmiMoJo quotes SlashGear: We're still many years away from casual consumer trips to the Moon, but it's easy to fantasize about such trips. NASA is getting in on the fun with a new campaign presenting the public with a simple question: what would you pack if you were taking your own lunar trip? NASA is encouraging anyone interested to share a picture of what's in their bag (for this imagined Moon trip) using its new #NASAMoonKit social campaign...

NASA is encouraging the public to get a container that meets this volume limitation, pack it with the precious few items they'd bring along on the trip, then take a picture and share it on social media — either Instagram, Facebook, or Twitter — using the #NASAMoonKit hashtag. NASA says that it may share your post on its own social accounts if it likes what it sees.
"What can't you leave the planet without?" asks the campaign's official web page. "Is it your camera? Your drawing pad? Or maybe your musical instrument?

"How would you organize everything you need for your next giant leap?"

schwit1 shares a report from UPI: NASA will fund a project by Nokia to build a 4G cellular communication network on the moon with $14.1 million, the space agency announced. That project was part of $370 million in new contracts for lunar surface research missions NASA announced Wednesday. Most of the money went to large space companies like SpaceX and United Launch Alliance to perfect techniques to make and handle rocket propellant in space. The space agency must quickly develop new technologies for living and working on the moon if it wants to realize its goal to have astronauts working at a lunar base by 2028, NASA Administrator Jim Bridenstine said in a live broadcast.

NASA has announced more than a third of a billion dollars worth of "Tipping Point" contracts awarded to over a dozen companies pursuing potentially transformative space technologies. The projects range from in-space testing of cryogenic tech to a 4G LTE network for the Moon. From a report: The space agency is almost always accepting applications for at least one of its many grant and contract programs, and Tipping Point is directly aimed at commercial space capabilities that need a bit of a boost. According to the program description, "a technology is considered at a tipping point if an investment in a demonstration will significantly mature the technology, increase the likelihood of infusion into a commercial space application, and bring the technology to market for both government and commercial applications."

A reader shares a report from SciTechDaily: Using telescopes from the European Southern Observatory (ESO) and other organizations around the world, astronomers have spotted a rare blast of light from a star being ripped apart by a supermassive black hole. The phenomenon, known as a tidal disruption event, is the closest such flare recorded to date at just over 215 million light-years from Earth, and has been studied in unprecedented detail. The research is published today in Monthly Notices of the Royal Astronomical Society.

"We found that, when a black hole devours a star, it can launch a powerful blast of material outwards that obstructs our view," explains Samantha Oates, also at the University of Birmingham. This happens because the energy released as the black hole eats up stellar material propels the star's debris outwards. The discovery was possible because the tidal disruption event the team studied, AT2019qiz, was found just a short time after the star was ripped apart. "Because we caught it early, we could actually see the curtain of dust and debris being drawn up as the black hole launched a powerful outflow of material with velocities up to 10 000 km/s," says Kate Alexander, NASA Einstein Fellow at Northwestern University in the US. "This unique 'peek behind the curtain' provided the first opportunity to pinpoint the origin of the obscuring material and follow in real time how it engulfs the black hole."

"Astrobiologists have identified 24 exoplanets that aren't just potentially habitable, they're potentially superhabitable, exhibiting an array of conditions more suitable to life than what's seen on Earth..." reports Gizmodo: For exoplanets to be superhabitable, they should be older, larger, heavier, warmer, and wetter compared to Earth, and ideally located around stars with longer lifespans than our own. So yeah, not only is Earth inferior, so too is our Sun, according to the new research...

As the new study points out, planets marginally older than Earth have a greater chance of being more habitable. When planets get old, "exhaustion of internally generated heat may result in eventual cooling, with consequences for global temperatures and atmospheric composition," write the authors. Earth is 4.5 billion years old, but planets between the ages of 5 billion and 8 billion years are likely to be more habitable, simply from a probabilistic standpoint...

To be clear, many of the criteria, such as atmospheric oxygen, plate tectonics, geomagnetism, and natural satellites, are currently beyond our ability to detect. What's more, only two of these planets, Kepler 1126 b and Kepler-69c, are scientifically validated planets, the remainder being on the list of unconfirmed Kepler Objects of Interest. Consequently, some of these "exoplanets" might not even be planets at all...

There are other limitations to consider as well. The authors are naturally biased towards Earth-like conditions, given that our planet provides the only known example of habitability. Life may proliferate under conditions not yet understood, and it's important to keep that in mind... We also don't know about the potential knock-off effects of these conditions. They sound good on paper, but the reality could be vastly different, as these environmental characteristics could collectively result in conditions wholly unsuitable for life.
"What's useful here is the criteria for planets that may not look exactly like Earth, but could be even more awesome locations for life," writes CNET.

"This could help us direct the resources of next-generation space telescopes like NASA's much-delayed James Webb."

sciencehabit writes: OSIRIS-REx is ready to get the goods. On 20 October, after several years of patient study of its enigmatic target, NASA's $800 million spacecraft will finally stretch out its robotic arm, swoop to the surface of the near-Earth asteroid Bennu, and sweep up some dust and pebbles. The encounter, 334 million kilometers from Earth, will last about 10 seconds. If it is successful, OSIRIS-REx could steal away with up to 1 kilogram of carbon-rich material from the dawn of the Solar System for return to Earth in 2023. Since OSIRIS-REx (short for Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer) arrived in 2018, Bennu has yielded surprises, not all of them welcome. The 500-meter-wide asteroid was not smooth, as expected, but studded with more than 200 large boulders that could upset the sampling maneuver. And every so often, the asteroid ejected coin-size pebbles, probably propelled by meteoroid impacts or solar heating. The boulder hazard, in particular, forced the team to target an area just 16 meters across for sampling, 10 times smaller than planned. "Bennu has not made things easy for us," says Mike Moreau, the mission's deputy project manager at NASA's Goddard Space Flight Center.

Despite the logistical challenge, the boulders contain a prize: veins of carbonate minerals thicker than your hands, the team reports in one of six studies published today in Science and Science Advances. The minerals, which precipitate out of hot water, popped out of data gathered during a close flyby of light-colored boulders near the target site, called Nightingale. Researchers believe the veins grew in channels of fluid circulating within Bennu's parent body, a larger planetesimal thought to have formed beyond Jupiter's orbit soon after the dawn of the Solar System 4.56 billion years ago, before being smashed apart in the asteroid belt within the last billion years. Heat from the decay of radioactive elements in its interior presumably drove the churning, and the presence of so much carbonate "suggests large-scale fluid flow, possibly over the entire parent body," says Hannah Kaplan, a planetary scientist at Goddard who led the work. This ancient water world is consistent with the idea that objects like Bennu delivered much of Earth's water when they struck the planet billions of years ago, says Dante Lauretta, the mission's principal investigator and a planetary scientist at the University of Arizona. The veins also suggest watery bodies like Bennu were a cauldron for the organic chemistry that generated the amino acids and other unusual prebiotic compounds found in carbon-rich meteorites.

An anonymous reader quotes a report from Ars Technica: An independent panel that assesses the safety of NASA activities has raised serious questions about the space agency's plan to test flight software for its Moon missions. During a Thursday meeting of the Aerospace Safety Advisory Panel, one of its members, former NASA Flight Director Paul Hill, outlined the panel's concerns after speaking with managers for NASA's first three Artemis missions. This includes a test flight of the Space Launch System rocket and Orion spacecraft for Artemis I, and then human flights on the Artemis II and III missions. Hill said the safety panel was apprehensive about the lack of "end-to-end" testing of the software and hardware used during these missions, from launch through landing. Such comprehensive testing ensures that the flight software is compatible across different vehicles and in a number of different environments, including the turbulence of launch and maneuvers in space.

"The panel has great concern about the end-to-end integrated test capability plans, especially for flight software," Hill said. "There is no end-to-end integrated avionics and software test capability. Instead, multiple and separate labs, emulators, and simulations are being used to test subsets of the software." The safety panel also was struggling to understand why, apparently, NASA had not learned its lessons from the recent failed test flight of Boeing's Starliner spacecraft, Hill said. (Boeing is also the primary contractor for the Space Launch System rocket's core stage). Prior to a test flight of the Starliner crew capsule in December 2019, Boeing did not run integrated, end-to-end tests for the mission that was supposed to dock with the International Space Station. Instead of running a software test that encompassed the roughly 48-hour period from launch through docking to the station, Boeing broke the test into chunks. As a result, the spacecraft was nearly lost on two occasions and did not complete its primary objective of reaching the orbiting laboratory.

"They're trolling us... we think. But how the hell did this get published?" asks Popular Mechanics.

Slashdot reader worldofsimulacra shares their report: Scientists have uncovered a bizarre, indefensible paper that squeaked through peer review at what appears at first pass to be a legitimate medical journal... 13 listed authors from wildly different fields throw together a series of escalating falsehoods. "Recently, some scientists from NASA have claimed that there may be a black hole like structure at the centre of the earth," the abstract begins. It only gets crazier from there:

"The earth's core is the biggest system of telecommunication which exchanges waves with all DNAs and molecules of water. Imaging of DNAs on the interior of the metal of the core produces a DNA black brane with around 109 times longer than the core of the earth which is compacted and creates a structure similar to a black hole or black brane. We have shown that this DNA black brane is the main cause of high temperature of core and magnetic of earth...."

One of the theories to explain the paper is that it was generated using "peer-review-tricking" artificial intelligence, which shuffles key terms and phrases and glues them together into something almost coherent.
Apparently you can't trust everything you read in the Open Access Macedonian Journal of Medical Sciences. The paper's title? "A Black Hole at the Center of Earth Plays the Role of the Biggest System of Telecommunication for Connecting DNAs, Dark DNAs and Molecules of Water on 4+N- Dimensional Manifold."

At the top of the paper, the journal has since appended a retraction, leading to a page warning "An internal investigation" has "raised sufficient evidence" that the paper is "not directly connected with the special issue Global Dermatology and contain inconsistent results...

"We apologize to our audience about this unfortunate situation."

"To teach the next generation of computer scientists the basics of Python programming, Microsoft recently announced a partnership with NASA to create a series of lessons based on space exploration efforts," reports TechRepublic: Overall, the project includes three different NASA-inspired lessons... The Introduction to Python for Space Exploration lesson will provide students with "an introduction to the types of space exploration problems that Python and data science can influence." Made up of eight units in total, this module also details the upcoming Artemis lunar exploration mission.

In another learning path, students will learn to design an AI model capable of classifying different types of space rocks depicted in random photos, according to Microsoft. However, the company recommends a "basic understanding of Python for Data Science" as a prerequisite for this particular lesson. The last of the three learning paths serves as an introduction to machine learning and demonstrates ways these technologies can help assist with space exploration operations.

Students are presented real-world NASA challenges, particularly rocket launch delays, and learn how the agency can leverage machine learning to resolve the issues... Microsoft also announced partnerships with Wonder Woman 1984 and Smithsonian Learning Labs to curate five additional programming lessons for students.

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.

AmiMoJo writes: Americans exercise their right to vote from all over the world, and for November's election, few ballots will have traveled as far as those cast by NASA astronauts living and working aboard the International Space Station. During earlier days of human spaceflight, astronauts would only visit space for days, or maybe weeks, at a time. Today, astronauts typically stay in space for six-month missions on the space station, increasing the odds of a spacefarer off the planet during an election. So how does one vote from space? Like other forms of absentee voting, voting from space starts with a Federal Postcard Application, or FPCA. It's the same form military members and their families fill out while serving outside of the U.S. By completing it ahead of their launch, space station crew members signal their intent to participate in an election from space. Because astronauts move to Houston for their training, most opt to vote as Texas residents. Of course, NASA's astronauts come from all over, so those wishing to vote as residents of their home states can work with their counties to make special arrangements to vote from space.

Once their FPCA is approved, the astronaut is almost ready to vote. Like many great things in space, voting starts with an experiment. The county clerk who manages elections in the astronaut's home county sends a test ballot to a team at NASA's Johnson Space Center in Houston. Then they use a space station training computer to test whether they're able to fill it out and send it back to the county clerk. After a successful test, a secure electronic ballot generated by the Clerk's office of Harris County and surrounding counties in Texas, is uplinked by Johnson's Mission Control Center to the voting crew member. An e-mail with crew member-specific credentials is sent from the County Clerk to the astronaut. These credentials allow the crew member to access the secure ballot. The astronaut will then cast their vote, and the secure, completed ballot is downlinked and delivered back to the County Clerk's Office by e-mail to be officially recorded. The clerk has their own password to ensure they are the only one who can open the ballot. It's a quick process, and the astronaut must be sure to submit it by 7 p.m. local time on Election Day if voting as a Texas resident.

Will astronauts vote in this election? Expedition 63/64 crew member Kate Rubins is assigned to a six-month mission launching Oct. 14, and will vote from space. It won't be her first time -- Rubins also cast her vote from the International Space Station during the 2016 election. With a SpaceX Crew Dragon scheduled to carry three additional U.S. crew members to the space station on Oct. 31 as part of the Crew-1 mission, Mike Hopkins, Victor Glover and Shannon Walker will make it to the space station just in time to cast their ballots there, as well. All three have filled out the paperwork and are ready to do so.

An anonymous reader quotes Teslarati: On August 19th this year, astronomers using the Panoramic Survey Telescope and Rapid Response System observatory in Hawaii spotted an object destined to enter Earth orbit this fall. Designated as object 2020 SO, the item is now believed to be a rocket booster from NASA's Surveyor 2 mission which crash landed on the Moon in 1966 during the Apollo-era of the Cold War's space race.

"I suspect this newly discovered object 2020 SO to be an old rocket booster because it is following an orbit about the Sun that is extremely similar to Earth's, nearly circular, in the same plane, and only slightly farther away the Sun at its farthest point," Dr. Paul Chodas, the director of NASA's Center for Near Earth Object Studies, explained in comments to CNN.

"That's precisely the kind of orbit that a rocket stage separated from a lunar mission would follow, once it passes by the Moon and escapes into orbit about the Sun. It's unlikely that an asteroid could have evolved into an orbit like this, but not impossible," he said. This specific type of event has only happened once before, namely in 2002 with a Saturn V upper stage from Apollo 12, according to Dr. Chodas.

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.

Last year, NASA had said that in four years, it would be landing the first woman ever on the moon, and returning to Earth's only natural satellite for the first time since 1972, through its Artemis programme. Now, in a release on September 22, NASA has shared an update outlining its plan, announcing a whopping $28 billion plan for the return to the lunar surface. From a report: The funds are all going to be used for the development of machinery; one billion dollars of the budget will go directly to the development of a commercial human lunar system that will take humans to the moon's surface. An allotment of $651 million will be used to support the Orion Spacecraft and the rocket that Boeing is building for the moon mission -- called the Space Launch System or SLS, on which NASA has already spent at least $11.9 billion.

The mission is named Artemis after the Greek goddess of the moon and the twin sister of Apollo. It's the antithesis to the NASA mission which last landed humans on the moon, Apollo 17. Only 12 humans, all male, have ever walked on the moon and they were all American, according to Bettina Inclan, NASA Communications Director. And with Artemis, they are finally planning to launch women on our satellite too. Currently, there are just 12 active women astronauts, excluding the five other female astronauts who graduated from training earlier this year. The crew for the 2024 mission, however, has not yet been named. According to NASA Administrator Jim Bridenstine, the first woman to walk on the moon would be somebody "who has been proven, somebody who has flown, somebody who has been on the International Space Station already."

An anonymous reader shares a report: Everyone's favorite mathematical constant has received an inadvertent tribute from the universe. A team led by MIT researchers discovered a distant planet that orbits its star every 3.14 days, mirroring the famous first three digits of pi. MIT described the rocky Earth-sized planet K2-315b as "baking hot" and "likely not habitable" in a statement on Monday. "The planet moves like clockwork," said MIT graduate student Prajwal Niraula, lead author of a paper on the planet published in the Astronomical Journal this week. The team found the exoplanet (a planet located outside our solar system) in data gathered in 2017 by NASA's Kepler Space Telescope K2 mission. The planet-finding telescope was put into a permanent sleep mode in 2018. The researchers confirmed the planet's existence by taking another look with the ground-based Speculoos telescope network. "Speculoos" stands for "Search for habitable Planets EClipsing ULtra-cOOl Stars." It's also a fun reference to a type of spiced cookie.

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.

"Earlier this week, scientists announced the discovery of phosphine on Venus, a potential signature of life. Now, in an amazing coincidence, a European and Japanese spacecraft is about to fly past the planet — and could confirm the discovery," writes Forbes. A Slashdot reader shares their report: BepiColombo, launched in 2018, is on its way to enter orbit around Mercury, the innermost planet of the Solar System. But to achieve that it plans to use two flybys of Venus to slow itself down, one on October 15, 2020, and another on August 10, 2021. The teams running the spacecraft already had plans to observe Venus during the flyby. But now, based on this detection of phosphine from telescopes on Earth, they are now planning to use both of these flybys to look for phosphine using an instrument on the spacecraft...

As this first flyby is only weeks away, however, the observation campaign of the spacecraft is already set in stone, making the chance of a discovery slim. More promising is the second flyby next year, which will not only give the team more time to prepare, but also approach just 550 kilometers from Venus...

If a detection can be made, it would provide independent verification of the presence of phosphine in the atmosphere of Venus. And for future missions planning to visit the planet, which alongside Rocket Lab's mission includes potential spacecraft from NASA, India, Russia, and Europe, that could be vital information.

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.
