NASA has announced that the often delayed James Webb space telescope (JWST) is to be delayed once more. Instead of a launch on 30 March 2021, the mission has now slipped to 31 October 2021. From a report: The seven-month delay is the result of impacts from the coronavirus pandemic, as well as technical challenges. The spacecraft is currently being tested at Northrop Grumman, NASA's main industrial partner on the mission, in Redondo Beach, California. A recently completed risk assessment exercise recommended the delay. Once ready, JWST will be transported to Europe's spaceport in Kourou, French Guiana, where it will be launched by the European Space Agency on an Ariane 5 ECA rocket. Touted as the successor to the Hubble space telescope, JWST has had a troubled development characterised by major cost overruns and delays. Development work started in the late 1990s, with a launch date set for 2007.

AmiMoJo shares a report from the BBC: China has launched its first rover mission to Mars. The six-wheeled robot, encapsulated in a protective probe, was lifted off Earth by a Long March 5 rocket from the Wenchang spaceport on Hainan Island at 12:40 local time (04:40 GMT). It should arrive in orbit around the Red Planet in February. Called Tianwen-1, or "Questions to Heaven," the rover won't actually try to land on the surface for a further two to three months. This wait-and-see strategy was used successfully by the American Viking landers in the 1970s. It will allow engineers to assess the atmospheric conditions on Mars before attempting what will be a hazardous descent. Tianwen-1 is one of three missions setting off to Mars in the space of 11 days. On Monday, the United Arab Emirates (UAE) launched its Hope satellite towards the Red Planet. And in a week from now, the U.S. space agency (Nasa) aims to despatch its next-generation rover, Perseverance.

Scientists have identified 37 volcanic structures on Venus that appear to be recently active -- and probably still are today -- painting the picture of a geologically dynamic planet and not a dormant world as long thought. NBC News reports: The research focused on ring-like structures called coronae, caused by an upwelling of hot rock from deep within the planet's interior, and provided compelling evidence of widespread recent tectonic and magma activity on Venus's surface, researchers said on Monday. Coronae are essentially fields of lava flows and major faults spanning a large circular area. Many of the 37 reside within in a gigantic ring in the planet's Southern Hemisphere, including a colossal corona called Artemis 1,300 miles (2,100 km) in diameter.

Many scientists long had thought Venus, lacking the plate tectonics that gradually reshape Earth's surface, was essentially dormant geologically for the past half billion years. The researchers determined the type of geological features that could exist only in a recently active corona - a telltale trench surrounding the structure. Then they scoured radar images of Venus from NASA's Magellan spacecraft in the 1990s to find coronae that fit the bill. Of 133 coronae examined, 37 appear to have been active in the past 2 million to 3 million years, a blink of the eye in geological time. The research has been published in the journal Nature Geoscience.

The first Arab space mission to Mars has blasted off aboard a rocket from Japan, with its unmanned probe -- called Al-Amal, or Hope -- successfully separating about an hour after liftoff. The Guardian reports: The Emirati project is one of three racing to Mars, including Tianwen-1 from China and Mars 2020 from the United States, taking advantage of a period when the Earth and Mars are nearest. In October, Mars will be a comparatively short 38.6m miles (62m km) from Earth, according to Nasa. Hope is expected to reach Mars's orbit by February 2021, marking the 50th anniversary of the unification of the UAE, an alliance of seven emirates. Unlike the two other Mars ventures scheduled for this year, it will not land on the planet, but instead orbit it for a whole Martian year, or 687 days.

While the objective of the Mars mission is to provide a comprehensive image of the weather dynamics in the red planet's atmosphere, the probe is a foundation for a much bigger goal -- building a human settlement on Mars within the next 100 years. The UAE also wants the project to serve as a source of inspiration for Arab youth, in a region too often wracked by sectarian conflicts and economic crises. On Twitter, the UAE's government declared the probe launch a "message of pride, hope and peace to the Arab region, in which we renew the golden age of Arab and Islamic discoveries."

The United Arab Emirates has successfully launched a spacecraft towards an orbit around Mars, reports the New York Times. Built by a space physics lab at the University of Colorado, the Hope Mars probe was tested in Dubai, before being shipped to Japan's Tanegashima Island, where it was launched by Mitsubishi Heavy Industries. The launch is being streamed on the web and on YouTube. It will join a fleet of six other spacecrafts studying the red planet from space, three operated by NASA, two by the European Space Agency (one shared with Russia) and one by India. Each contains different instruments to help further research of the Martian atmosphere and surface.

The Hope orbiter is carrying three instruments: an infrared spectrometer, an ultraviolet spectrometer and a camera. From its high orbit — varying from 12,400 miles to 27,000 miles above the surface — the spacecraft will give planetary scientists their first global view of Martian weather at all times of day. Over its two-year mission, it will investigate how dust storms and other weather phenomena near the Martian surface have either speed or slow the loss of the planet's atmosphere into space.
"You'll be hearing a lot about Mars this summer," the Times adds. "Three missions are launching toward the red planet, taking advantage of the way Earth and its neighbor get closer every 26 months or so, allowing a relatively short trip between the two worlds." The next expected launch will be China's Tianwen-1, which could occur between later this week through early August... On July 30, NASA is scheduled to launch Perseverance, a robotic rover that will be the fifth wheeled American vehicle to explore Mars... A fourth mission, the joint Russian-European Rosalind Franklin rover, was to launch this summer, too. But technical hurdles, aggravated by the coronavirus pandemic, could not be overcome in time to meet the launch window. It is now scheduled to launch in 2022.
If the other three spacecraft all launch successfully, they should arrive at Mars early next year.

The launch of NASA's next flagship space telescope has been pushed back another seven months. Space.com reports: The liftoff of the $9.8 billion James Webb Space Telescope has been delayed from March 2021 until Oct. 31 of that year, NASA officials announced today (July 16), citing technical difficulties as well as complications imposed by the coronavirus pandemic. "Webb is the world's most complex space observatory, and our top science priority, and we've worked hard to keep progress moving during the pandemic," Thomas Zurbuchen, associate administrator of NASA's Science Mission Directorate, said in a statement. "The team continues to be focused on reaching milestones and arriving at the technical solutions that will see us through to this new launch date next year."

NASA officials attributed three months of this latest seven-month delay to the coronavirus pandemic, which forced many NASA centers to impose mandatory work-from-home orders. "Risk reduction" work on complex Webb tech, such as the observatory's huge, foldable sunshield, added two more months. The remaining two months were added for "schedule margin," giving the mission some breathing room on its long road to the launch pad. But the schedule slip won't increase the 13,670-lb. (6,200 kilograms) Webb's hefty price tag, mission team members said. "Based on current projections, the program expects to complete the remaining work within the new schedule without requiring additional funds," Gregory Robinson, NASA Webb program director at the agency's headquarters in Washington, D.C., said in the same statement.

The world's fastest computer is now part of "a vast supercomputer-powered search for new findings pertaining to the novel coronavirus' spread" and "how to effectively treat and mitigate it," according to an emerging tech journalist at Nextgov.

It's part of a consortium currently facilitating over 65 active research projects, for which "Dozens of national and international members are volunteering free compute time...providing at least 485 petaflops of capacity and steadily growing, to more rapidly generate new solutions against COVID-19."

"What started as a simple concept has grown to span three continents with over 40 supercomputer providers," Dario Gil, director of IBM Research and consortium co-chair, told Nextgov last week. "In the face of a global pandemic like COVID-19, hopefully a once-in-a-lifetime event, the speed at which researchers can drive discovery is a critical factor in the search for a cure and it is essential that we combine forces...."

[I]ts resources have been used to sort through billions of molecules to identify promising compounds that can be manufactured quickly and tested for potency to target the novel coronavirus, produce large data sets to study variations in patient responses, perform airflow simulations on a new device that will allow doctors to use one ventilator to support multiple patients — and more. The complex systems are powering calculations, simulations and results in a matter of days that several scientists have noted would take a matter of months on traditional computers.
The Undersecretary for Science at America's Energy Department said "What's really interesting about this from an organizational point of view is that it's basically a volunteer organization."

The article identifies some of the notable participants:

• IBM was part of the joint launch with America's Office of Science and Technology Policy and its Energy Department.
• The chief of NASA's Advanced Supercomputing says they're "making the full reserve portion of NASA supercomputing resources available to researchers working on the COVID-19 response, along with providing our expertise and support to port and run their applications on NASA systems."
• Amazon Web Services "saw a clear opportunity to bring the benefits of cloud... to bear in the race for treatments and a vaccine," according to a company executive.
• Japan's Fugaku — "which surpassed leading U.S. machines on the Top 500 list of global supercomputers in late June" — also joined the consortium in June.

Other consortium members:

• Google Cloud
• Microsoft
• Massachusetts Institute of Technology
• Rensselaer Polytechnic Institute
• The National Science Foundation
• Argonne, Lawrence Livermore, Los Alamos, Oak Ridge and Sandia National laboratories.
• National Center for Atmospheric Research's Wyoming Supercomputing Center
• AMD
• NVIDIA
• Dell Technologies. ("The company is now donating cycles from the Zenith supercomputer and other resources.")

"A newly-discovered comet is giving skywatchers quite the show during the month of July," reports CBS News: Astronomers discovered the comet, known as Comet C2020 F3 NEOWISE, back in March. It was named for the NASA mission that spotted it, for the Near-Earth Object Wide-field Infrared Survey Explorer... But astronomers knew they found something unique when they spotted Neowise. On July 3, Neowise was closer to the sun than the orbit of Mercury, coming dangerously close to breaking apart. The sun heated up much of the comet's icy makeup, erupting in a large debris trail of gas and dust.

Measuring about 3 miles across, Neowise is considered a fairly large comet — providing skywatchers with a spectacular view from Earth. The comet, which has a bright opulent tail, has been putting on a stunning show in the early hours before sunrise in the Northern Hemisphere... But late sleepers need not worry — the comet will start appearing in the evening, just after sunset, starting Saturday.

To view it, people in the Northern Hemisphere can look to the northwestern sky, just below Ursa Major, commonly known as the Big Dipper constellation. Scientists say the comet will be visible across the Northern Hemisphere for about another month.
The comet is made up of material dating back 4.6 billion years, to the origins of our solar system, according to the article. "The event is truly a once-in-a-lifetime experience — the comet takes about 6,800 years to complete its path around the sun, according to NASA..."

"NASA says it will be one of the brightest comets this century."

Trying to get an up close and personal look at the solar system's gas giants is a tricky and dangerous journey. From a report: Jupiter, like the other gas giants, doesn't have a rocky surface, but that doesn't mean it's just a massive cloud floating through the vacuum of space. It's made up of mostly helium and hydrogen, and as you move from the outer layers of the atmosphere toward the deeper parts, that gas grows denser and the pressures become more extreme. Temperatures quickly rise. In 1995, NASA's Galileo mission sent a probe into Jupiter's atmosphere; it broke up at about 75 miles in depth. Pressures here are over 100 times more intense than anything on Earth. At the innermost layers of Jupiter that are 13,000 miles deep, the pressure is 2 million times stronger than what's experienced at sea level on Earth, and temperatures are hotter than the sun's surface.

So clearly, no human is going to be able to venture too far down into Jupiter's depths. But would it be safe to simply orbit the planet? Perhaps we could establish an orbital space station, right? Well, there's another big problem when it comes to Jupiter: radiation. The biggest planet in the solar system also boasts its most powerful magnetosphere. These magnetic fields charge up particles in the vicinity, accelerating them to extreme speeds that can fry a spacecraft's electronics in moments. Spaceflight engineers have to figure out an orbit and spacecraft design that will reduce the exposure to this radiation. NASA figured this out with the triple-arrayed, perpetually spinning Juno spacecraft, but it doesn't look as if this would be a feasible design for a human spacecraft. Instead, for a crewed spacecraft to safely orbit or fly past Jupiter, it would have to keep a pretty significant distance away from the planet.

"If your family's Fourth of July fireworks plans are up in smoke because of the pandemic, watch the sky for a lunar eclipse instead," reports CNN.

It begins in just 5 minutes -- and then lasts for two hours and 45 minutes: On July 4, just after 11 p.m. ET, the moon will begin its temporary new look. For exactly two hours and 45 minutes, the moon will pass through the feathered outer shadow cast from Earth, creating a partial penumbral lunar eclipse.

A penumbral lunar eclipse occurs when the moon passes through the faint penumbra shadow cast by Earth. The moon misses the Earth's umbral shadow, which is best known for creating total and partial lunar eclipses. This event might not be as illustrious as a partial or total lunar eclipse where parts of the moon seem to disappear. Still, a noticeable darkening of the moon's surface will be visible without a telescope.

The eclipse will begin at 11:07 p.m. ET and last through 1:52 a.m. ET, with peak darkening occurring just after midnight.
The article also notes that every night this summer will see "a great meeting of planets, known by astronomers as a conjunction... Expect a brighter than usual illumination of the planets as they take center stage across the horizon."

While Jupiter will be 15 times brighter than Saturn, they'll both be approaching their closest approach to Earth in 20 years — which finally happens in mid-July.

"They've been up there about a month now, floating around on the International Space Station, keeping tabs on their ride home," reports the Washington Post: "Certainly, the highlight for both Doug and I was the initial arrival at space station, coming through the hatch again and being on board after several years of working on a new spacecraft," Behnken said in an interview from the station this week. Since then, he has performed two spacewalks with Cassidy, successfully replacing batteries on the outside of the station... Now, NASA and the astronauts are turning their focus to the return trip. At the moment, the space agency says the soonest Behnken and Hurley could return is Aug. 2.

If all goes well, the Dragon would undock from the station, fire its thrusters and descend through the atmosphere. The entire mission is a test to see how SpaceX's Dragon capsule performs, and while NASA said its ascent went flawlessly, there still are many risks ahead. As it plunges down, the thickening air will cause friction and generate enormous heat, testing the capsule's heat shield. Then the spacecraft's parachutes are to deploy to slow the vehicle further. SpaceX has struggled with its parachute designs in the past, however. "Parachutes are way harder than they look," Elon Musk said in an interview with The Post before the launch. "The Apollo program actually had a real morale issue with the parachutes because they were so damn hard. They had people quitting over how hard the parachutes were. And then you know we almost had people quit at SpaceX over how hard the parachutes were. I mean they soldiered through, but, man, the parachutes are hard."

Another risk will be landing in the ocean. American astronauts have not splashed down in the water since 1975 — the Space Shuttles landed on land, as do the Russian Soyuz spacecraft. Behnken said he and Hurley expect to spend about an hour bobbing on the ocean surface before they are hoisted on the deck of a ship. SpaceX has been training extensively for the recovery mission, working to get the astronauts to safety as quickly as possible, but that will also be a key test.

Amazon.com is boosting efforts to lure military and commercial space organizations as major users of its cloud-computing services, hoping to benefit from rising government spending and burgeoning private investment. From a report: The move by Amazon Web Services, the online retail giant's cloud-computing arm, comes during a multiyear surge in U.S. military and civilian agency spending on space projects, with NASA, the Pentagon and their largest contractors -- including Lockheed Martin -- benefiting from hefty appropriated or proposed budget increases. Lockheed Martin already is an Amazon customer. Capitol Hill is pouring billions of dollars into new boosters and the next generation of superfast missiles, driven, in part, by White House and intelligence community warnings about Chinese and Russian advances in space. Commercial companies are building or planning to deploy swarms of small satellites encircling the globe, though the Covid-19 pandemic has dimmed the immediate outlook for many private space projects.

Amazon is anticipating a huge increase in space-related cloud-computing contracts globally with a market size estimated at hundreds of billions of dollars, said Teresa Carlson, AWS's vice president in charge of public sector business. "There's a need for a more modernized approach to this industry," Ms. Carlson said. AWS will formally announce it is establishing a dedicated segment, called Aerospace and Satellite Solutions, at an online summit focused on business with the public sector on Tuesday. The group will be run by retired Air Force Maj. Gen. Clint Crosier, who, until recently, was in charge of planning to set up the Space Force, the newly created branch of the military. The initiative comes as AWS faced increased pressure from cloud-computing rivals for public sector business. Last year, AWS lost out to Microsoft in a high-profile competition to provide the Pentagon cloud-computing services. The program, known as JEDI, could be worth up to $10 billion over 10 years. Amazon has challenged the outcome.

An anonymous reader quotes a report from Ars Technica: A hot desert wind is carrying a massive cloud of Saharan dust into the Southern United States this week. Dust plumes from the Sahara routinely blow westward across the Atlantic at this time of year, but this event is a doozy -- by some measures, the biggest in decades. And a second plume appears to be forming about a week behind the big one. Across the southeastern US, from the Gulf Coast to the Carolinas and potentially as far north as Indianapolis and Cincinnati, dust effects will likely be visible in the coming days. Trillions of dust grains will reflect sunlight in every direction, creating milky white skies. The dusty haze reflects some sunshine back to space, cooling the surface a bit where the plume is thickest.

Longer waves of red and orange light tend to penetrate the dusty haze, so sunrises and sunsets are likely to be especially beautiful. On the downside, where the plume mingles with showers or thunderstorms, downdrafts may carry desert dust to Earth's surface. This will impair air quality and could trigger allergic reactions and asthma attacks. The more dust reaches an area, the more pronounced the effects will be. Scott Denning, climate scientist and professor of atmospheric science at Colorado State University, goes on to describe what causes these plumes to form.

As part of NASA's next mission to Mars, leaving Earth this summer, the space agency will attempt to do something that has never been done before: fly a helicopter through the rarefied atmosphere of Mars. The New York Times reports: If it works, the small helicopter, named Ingenuity, will open a new way for future robotic explorers to get a bird's-eye view of Mars and other worlds in the solar system. "This is very analogous to the Wright brothers moment, but on another planet," said MiMi Aung, the project manager of the Mars helicopter at NASA's Jet Propulsion Laboratory over the past six years.

Flying on Mars is not a trivial endeavor. There is not much air there to push against to generate lift. At the surface of Mars, the atmosphere is just 1/100th as dense as Earth's. The lesser gravity -- one-third of what you feel here -- helps with getting airborne. But taking off from the surface of Mars is the equivalent of flying at an altitude of 100,000 feet on Earth. No terrestrial helicopter has ever flown that high, and that's more than twice the altitude that jetliners typically fly at. The copter will hitch a ride to the red planet with Perseverance, which is to be the fifth robotic rover NASA has sent there. The mission is scheduled to launch on July 20, one of three missions headed to Mars this year. At a news conference last week previewing the Perseverance mission, Jim Bridenstine, the NASA administrator, made a point to highlight Ingenuity. "I'll tell you, the thing that has me the most excited as an NASA administrator is getting ready to watch a helicopter fly on another world," he said.

The Washington Post reports: After a top NASA official improperly contacted a senior Boeing executive about a bid to win a contract potentially worth hundreds of millions of dollars, the company attempted to amend its proposal past the deadline for doing so, according to people with knowledge of the matter. That raised alarm bells inside the space agency, where officials were concerned that Boeing was attempting to take advantage of inside information. Ultimately, the matter was referred to NASA's inspector general office, and NASA's leadership last month forced Doug Loverro to resign from his position as the associate administrator of NASA's human spaceflight directorate.

Boeing did not win one of the lucrative contracts to build a system capable of landing astronauts on the moon. But the inspector general investigation could be another headache for a company under fire for having an unusually cozy relationship with federal regulators, especially if it identifies wrongdoing on the part of Boeing senior executives... "It's one thing to have a mistake that violated the Integrity in Procurement Act," according to a congressional aide with knowledge of the matter. "It's another if the company took that information and acted on it."

An anonymous reader quotes CBS News: Researchers, armchair astronauts and even brides and grooms looking for an out-of-this-world wedding experience will be able to celebrate, collect data or simply enjoy the view from an altitude of 100,000 feet in a balloon-borne pressurized cabin, complete with a bar and a restroom, a space startup announced Thursday.

"Spaceship Neptune," operated by a company called Space Perspective from leased facilities at NASA's Kennedy Space Center, will carry eight passengers at a time on six-hour flights [with a crew member]. The passenger cabin, lifted by a huge hydrogen-filled balloon, will climb at a sedate 12 miles per hour to an altitude of about 30 miles high. That will be followed by a slow descent to splashdown in the Atlantic Ocean where a recovery ship will be standing by to secure the cabin and crew.

Test flights carrying scientific research payloads are expected to begin in 2021. The first flights carrying passengers are expected within the next three-and-a-half years or so, with piloted test flights before that. While the company initially will operate out of the Florida spaceport, the system could be launched from multiple sites around the world, with Hawaii and Alaska near-term possibilities.
They're expecting to charge around $125,000 per passenger, according to the article — about half the price of higher sub-orbital flight on a Virgin Galactic rocket-powered spaceplane. Though Spaceship Neptune's customers will not experience weightlessness, their CEO is still promising "opportunities for civilian astronauts to experience this planet Earth from the edge of space, a privilege previously available to only a few."

And they're also touting "really great" live air-to-ground communication — which they think would be great for corporate events.

Slashdot reader shirappu writes: For eight years now, the Mars Rover Curiosity has been exploring the surface of Mars. Even now, it's still exploring, and still getting upgrades. According to Tech Crunch, NASA is now looking to interested volunteers to help upgrade the rover's terrain-scanning AI systems by annotating image data of the planet itself.
"The problem is that while there are lots of ready-made data sets of images with faces, cats and cars labeled, there aren't many of the Martian surface annotated with different terrain types..." notes TechCrunch. "Improvements to the AI might let the rover tell not just where it can drive, but the likelihood of losing traction and other factors that could influence individual wheel placement."

shirappu continues: Volunteers go through a short tutorial after which they can label images to help the rover better understand the terrain on which it drives. The system is expected to be used in future planet rover robots, and the project marks an interesting example of open crowd-sourcing to improve machine learning systems, and how it is impacting technology even on other planets.

Planetary scientist Lynnae Quick decided to explore whether -- hypothetically -- ocean planets, similar to Saturn's moon Enceladus and Jupiter's moon Europa, are common in the Milky Way galaxy. "Through a mathematical analysis of several dozen exoplanets, including planets in the nearby TRAPPIST-1 system, Quick and her colleagues learned something significant: More than a quarter of the exoplanets they studied could be ocean worlds, with a majority possibly harboring oceans beneath layers of surface ice, similar to Europa and Enceladus," reports Phys.Org. "Additionally, many of these planets could be releasing more energy than Europa and Enceladus." From the report: To look for possible ocean worlds, Quick's team selected 53 exoplanets with sizes most similar to Earth, though they could have up to eight times more mass. Scientists assume planets of this size are more solid than gaseous and, thus, more likely to support liquid water on or below their surfaces. At least 30 more planets that fit these parameters have been discovered since Quick and her colleagues began their study in 2017, but they were not included in the analysis, which was published on June 18 in the journal Publications of the Astronomical Society of the Pacific. With their Earth-size planets identified, Quick and her team sought to determine how much energy each one could be generating and releasing as heat. The team considered two primary sources of heat. The first, radiogenic heat, is generated over billions of years by the slow decay of radioactive materials in a planet's mantle and crust. That rate of decay depends on a planet's age and the mass of its mantle. Other scientists already had determined these relationships for Earth-size planets. So, Quick and her team applied the decay rate to their list of 53 planets, assuming each one is the same age as its star and that its mantle takes up the same proportion of the planet's volume as Earth's mantle does.

Next, the researchers calculated heat produced by something else: tidal force, which is energy generated from the gravitational tugging when one object orbits another. Planets in stretched out, or elliptical, orbits shift the distance between themselves and their stars as they circle them. This leads to changes in the gravitational force between the two objects and causes the planet to stretch, thereby generating heat. Eventually, the heat is lost to space through the surface. One exit route for the heat is through volcanoes or cryovolcanoes. Another route is through tectonics, which is a geological process responsible for the movement of the outermost rocky or icy layer of a planet or moon. Whichever way the heat is discharged, knowing how much of it a planet pushes out is important because it could make or break habitability. For instance, too much volcanic activity can turn a livable world into a molten nightmare. But too little activity can shut down the release of gases that make up an atmosphere, leaving a cold, barren surface. Just the right amount supports a livable, wet planet like Earth, or a possibly livable moon like Europa.

Some have suggested that some of these planets could be watery, and Quick's estimates support this idea. According to her team's calculations, TRAPPIST-1 e, f, g and h could be ocean worlds, which would put them among the 14 ocean worlds the scientists identified in this study. The researchers predicted that these exoplanets have oceans by considering the surface temperatures of each one. This information is revealed by the amount of stellar radiation each planet reflects into space. Quick's team also took into account each planet's density and the estimated amount of internal heating it generates compared to Earth.

Later this year, the International Space Station will receive a new and improved toilet system designed to bridge the gap between current lavatorial space tech and what humans will need to make extended visits to, say, Mars, in comfort. Space.com reports: It has a fancier name, of course; officially, the commode is NASA's Universal Waste Management System (UWMS). The launch is targeted for no earlier than the fall, a NASA spokesperson confirmed to Space.com, although the agency is still determining what spacecraft will carry the new plumbing up. The toilet currently on offer on the U.S. side of the space station was designed in the 1990s and based on its shuttle counterpart, according to a detailed review of space toiletry. But the apparatus has its flaws. It can be clunky to use, particularly for women, and it is "sensitive to crew alignment on the seat," sometimes resulting in messes, according to that review.

So NASA has tried to keep the aspects that have gotten positive reviews while trimming mass and volume and making some design changes, like adjusting the shape of the seat and replacing the apparatus that compresses the waste. Another change mimics a feature of the toilet on the Russian side of the space station, where astronauts simply hook their feet into toe bars, rather than the thigh bars used on the American equivalent to anchor the astronaut in the microgravity environment. The UWMS will remain on the space station for the rest of the orbiting laboratory's lifetime, and a second toilet of the same model will fly on the Orion capsule that astronauts use to fly around the moon on the first crewed Artemis mission in NASA's ambitious lunar return plan, according to the agency.

Long-time Slashdot reader JoeRobe writes: Space.com and other outlets are reporting on new pictures of Wolf 359 and Proxima Centauri sent back from New Horizons. The images show clear parallax between the view from Earth and from the spacecraft 6.9 billion km away. In effect, New Horizons is looking up at a visually different star field than we are... NASA has even created stereoscopic pairs to get a 3D view.
"It's fair to say that New Horizons is looking at an alien sky, unlike what we see from Earth," New Horizons principal investigator Alan Stern said in a statement, according to Space.com: New Horizons captured the imagery on April 22 and April 23, when the probe was more than 4.3 billion miles (6.9 billion kilometers) from its home planet. That's so far away that it took 6.5 hours for the data containing the photos, moving at the speed of light, to travel from New Horizons to mission scientists' inboxes... The parallax demonstration was not done for scientific purposes, Stern told Space.com (though he did note that the New Horizons imagery might find its way into textbooks that discuss the parallax effect). Rather, the main goal was public outreach and engagement, and a desire to provide us all with some cosmic poetry and perspective.

We could get more such demonstrations, and much more data, from New Horizons in the coming years. The probe remains in good health and has enough fuel to fly by yet another object in the 2020s, if a suitable target can be found and NASA approves another mission extension, Stern and other team members have said.
On Friday five New Horizons scientists answered questions on Reddit, including New Horizons contributing scientist and astrophysicist Brian May (also a guitarist for the rock group Queen).

The team pointed out they could hypothetically maintain communication with their interplanetary space probe until it's 200 times as far from the Sun as the Earth is. (It's currently just 47 times as far...) "But power will run out before we get that far...somewhere near 100 times."
