RockDoctor writes: An ad hoc committee of the International Astronomical Union has been working for 5 months on revisions and clarifications to the definitions of various terms used in technical and popular discussions of SETI -- the Search For Extraterrestrial Intelligence. They've published their draft report.

The terms of reference -- to account for existing popular and technical uses of the terms -- should mean that no major changes in usage occur, but interesting points do emerge from the discussion paper. For example, in discussing the term "extraterrestrial," their proposed definition ("shorthand for life or technology not originating recently on Earth") includes cover for possibilities such as "panspermia" which may be popular in "popular science," but certainly are not popular in the technical discussions. They go on to discuss that "by this definition, life on another planet with a common origin to Earth life but which diverged billions of years ago would be extraterrestrial, but Earth life accidentally brought to Mars on a human-built lander would not." Waiting for the invasion of the pedants, clutching their feet in their hands.

NASA is challenging people in the United States to come up with an efficient method to convert carbon dioxide into glucose, a simple sugar. The atmosphere of Mars consists predominantly of CO2 (95%), and glucose is a great fuel for microbe-milking "bioreactors" that could manufacture a variety of items for future settlers of the Red Planet, NASA officials said. Space.com reports: The new competition consists of two phases. During Phase 1, applicants submit a detailed description of their CO2-to-glucose conversion system. Interested parties must register by Jan. 24, 2019 and submit their proposals by Feb. 28, 2019. In April, NASA will announce the selection of up to five finalists from this initial crop, each of whom will receive $50,000. Phase 2 will involve the construction and demonstration of a conversion system. Winning this round is worth $750,000, bringing the competition's total purse to $1 million (assuming five finalists are indeed selected from Phase 1). You don't have to win, or even participate in, Phase 1 to compete in Phase 2. The challenge is open to citizens and permanent residents of the United States; foreign nationals can compete if they're part of a U.S.-based team.

Eric Berger writes via Ars Technica: The Apollo missions that flew to the Moon during the 1960s were designed and controlled by what is now known as Johnson Space Center, the home of the famous "Mission Control." Moreover, the astronauts that flew to the Moon all lived in Houston. It would stand to reason, therefore, that as NASA gears up to return to the Moon, major elements of this program would likewise be controlled from the Texas metropolis that styles itself "Space City." Times change, however. In recent months, the politically well-positioned Marshall Space Flight Center, in Huntsville, Alabama, has been quietly pressing leaders with NASA Headquarters for program management of mid- to large-size landers to the lunar surface, which would evolve into human landers. Sources indicated this effort was having some success.

However, Texas legislators have now begun to push back. On Tuesday, both of Texas' senators (John Cornyn and Ted Cruz), as well as three representatives with space-related committee chairs (John Culberson, Lamar Smith, and Brian Babin), wrote a letter to NASA Administrator Jim Bridenstine. "We support NASA's focus on returning to the Moon and using it as part of a stepping stone approach to place American boots on the surface of Mars in the 2030s," the Texas Republicans wrote. "As NASA reviews solicitations for lunar landers, we write to express our strong support for the establishment of NASA's lunar lander program at the Johnson Space Center." The letter reminds Bridenstine of Houston's strong spaceflight heritage.

Vice President Mike Pence spoke at NASA's Johnson Space Center on Thursday about the agency's plans to send humans back to the moon for the first time in almost half a century and eventually on to Mars. He said: The next Americans who set foot on the Moon will start their journey by stepping through the NASA's Orion hatch. And this extraordinary spacecraft will one day bridge the gap between our planet and the next.

The International Space Station has been an unqualified success. Soon and very soon American astronauts will return to space on American rockets launched from American soil. America will not ever abandon the critical domain of space, we will open the way for innovators and development and we will lead once again in human exploration. Our administration is working tirelessly to put an American crew aboard the lunar orbital platform before the end of 2024. In a prepared statement, Pence added, "We're renewing our national commitment to discovery and exploration and write the next great chapter of our nation's journey into space. It's now the official policy of the US that we'll return to the Moon, put Americans on Mars and once again explore the farthest depths of outer space."

Two months have passed since NASA's Opportunity Mars rover last phoned home. The last time we reported on the rover was on June 12th, when it was trying to survive an intensifying dust storm that was deemed "much worse than a 2007 storm that Opportunity weathered," according to NASA. "The previous storm had an opacity level, or tau, somewhere above 5.5; this new storm had an estimated tau of 10.8." Space.com reports on Opportunity's current status: Opportunity hasn't made a peep since June 10, when dust in the Red Planet's air got so thick that the solar-powered rover couldn't recharge its batteries. Opportunity's handlers think the six-wheeled robot has put itself into a sort of hibernation, and they still hope to get a ping once the dust storm has petered out. And there are good reasons for this optimism, NASA officials said. "Because the batteries were in relatively good health before the storm, there's not likely to be too much degradation," NASA officials wrote in an Opportunity update Thursday (Aug. 16). "And because dust storms tend to warm the environment -- and the 2018 storm happened as Opportunity's location on Mars entered summer -- the rover should have stayed warm enough to survive."

Engineers are trying to communicate with Opportunity several times a week using NASA's Deep Space Network, a system of big radio dishes around the globe. They hail the robot during scheduled "wake-up times" and then listen for a response. And team members are casting a wider net, too: Every day, they sift through all radio signals received from Mars, listening for any chirp from Opportunity, NASA officials said. Even if Opportunity does eventually wake up and re-establish contact, its long ordeal may end up taking a toll on the rover. "The rover's batteries could have discharged so much power -- and stayed inactive so long -- that their capacity is reduced," NASA officials wrote in the update. "If those batteries can't hold as much charge, it could affect the rover's continued operations. It could also mean that energy-draining behavior, like running its heaters during winter, could cause the batteries to brown out."

India will launch its first manned space mission by 2022, the country's Prime Minister Narendra Modi said on Wednesday, which could make it the fourth nation to do so after the United States, Russia and China. From a report: Modi congratulated Indian scientists for excelling in their research and are at the forefront of innovation. "Our scientists have made us proud. They launched over 100 satellites... They successfully completed the Mars mission." ISRO, India's space agency, successfully launched 104 satellites on 15 February 2017, of which three were Indian while the rest were foreign commercial satellites. The Mars Orbiter Mission (MOM), also called Mangalyaan, India's first interplanetary mission was launched on November 5, 2013 by the Indian Space Research Organisation (ISRO). It has been orbiting Mars since September 24, 2014.

Claire Reilly, writing for CNET: After spending a night in an underground rock cave in the middle of the Australian desert, I learned three things: The silence is deafening. Your eyes never adjust to the darkness. And if nobody brushes the ceiling before you arrive, that clump of dirt is going to scare the living hell out of you when it drops on your face at 2 a.m. I've flown 1,200 miles for the privilege of sleeping in a hole in Coober Pedy. There's no Wi-Fi down here. The glare of my MacBook feels obnoxious in the subterranean stillness. The TV plays ads for a "local" cleaning service from the next town over, but that just happens to be 400 miles away. Australia is a country defined by "the tyranny of distance," but traveling to the underground opal mining town of Coober Pedy feels like taking a holiday on Mars.

In the middle of the South Australian desert and an eight hour drive in either direction from the nearest capital city (Adelaide to the south or Alice Springs to the north), Coober Pedy is off the grid and mostly hidden underground. More than half the residents live buried in the bedrock in cavelike homes called "dugouts" in order to escape freezing winters, scorching summers and the occasional cyclone. Often, the only sign you're walking on someone's roof is the air vent that's sprouted up next to your boots. While first nation peoples have lived in the central Australian desert for thousands of years, the Coober Pedy we know today wouldn't exist without opals. Miners rushed here in the 1920s, enduring extreme conditions to hunt for the multicolored gems, digging, bulldozing and eventually blasting out earth in a bid to find the elusive seam that would make them rich. Living in Coober Pedy is not just about surviving. It's about carving out a way of life in one of the harshest environments on the planet.

[...] "It's not like we're living thousands of kilometers under the ground," he tells me. "It's pretty similar to living in a normal house." Sam's family, who live in a dugout close to Crocodile Harry's, have solar panels for power -- but those generate only enough electricity for a few hours a day. Diesel handles the rest, he says. "We have to rely on tourists to pay for our fuel," he says. "Gasoline is valuable out here. Fuel is really expensive." That means no fridge running all day and night -- they keep nonperishable food and get the rest from town every day. Otherwise, life is pretty similar to what other 18-year-olds in the city experience. Sam says he can still charge his phone and use the TV "for a bit." "We have internet when the generator's on. Dad's got an Xbox but we don't even try to use the solar for that."

Zorro quotes a report from The Daily Beast: After years of planning, NASA is finally launching a new effort to send astronauts back to the moon and then onward to Mars. But one important piece of technology is missing: a new space suit. Fifty-three years after astronaut Ed White stepped outside his Gemini 4 capsule on the first-ever spacewalk for an American, NASA is stuck using decades-old suits that critics say are too old, too bulky, too rigid, and too few in number for America's new era of space exploration.

Astronauts could need as many as three different kinds of space suits for a single mission. NASA has plenty of flight-suit options, but its extravehicular activity or EVA suits are old and dwindling in number. And the agency doesn't have any suits specifically for surface missions. Time is running out to make up the space suit shortfalls. NASA plans to launch Exploration Mission 1, the first test of Orion and its heavy rocket, as early as 2020. The Lunar Gateway station could be ready for use five or six years later. Despite these looming deadlines, NASA "remains years away from having a flight-ready space suit... suitable for use on future exploration missions," the agency's inspector general warned in a 2017 audit.

Mars might not have the right ingredients to terraform into our planetary home away from home -- even with the recent discovery of liquid water buried near its south pole. From a report: Research published Monday in Nature Astronomy puts a kibosh on the idea of terraforming Mars. At the heart of the study is carbon dioxide. Carbon dioxide, a greenhouse gas, is abundant on Mars -- its thin atmosphere is made of the stuff, and the white stuff we often see on the surface is dry ice, not snow. CO2 is even trapped in the rocks and soil. That abundance has long fueled visions of a fantasy future where all that trapped carbon dioxide is released, creating a thicker atmosphere that warms the planet. SpaceX founder Elon Musk has even proposed nuking Mars to make this happen.

But in this new study, veteran Mars expert Bruce Jakosky of the University of Colorado Boulder and Christopher S. Edwards of Northern Arizona University, surveyed how much carbon dioxide is available for terraforming the Red Planet. They combined Martian CO2 observations from various missions -- NASA's MAVEN atmospheric probe, the European Space Agency's Mars Express orbiter, as well as NASA's Odyssey and the Mars Reconnaissance Orbiter. The results throw shade on the dreams of futurists.

pacopico writes: First World View hung Google SVP Alan Eustace at the end of a balloon and then dropped him 135,908 feet back to Earth. Then, it sent a KFC chicken sandwich to the edge of space. Now, World View has figured out how to get high-altitude balloons to sail winds in the stratosphere and travel for thousands of miles. They're being used to take detailed pictures of the Earth, send communications to far off places and learn more about the weather.

This strange company was founded by two people who lived in Biosphere 2, and they say they're doing all this balloon work to get people to think differently about the planet. In a few years, they plan to send people up to the edge of space in a capsule and let them hang out for a couple hours, while they sip cocktails and reflect on life or something like that.
The flights would cost $75,000 per person -- the money from KFC is already being used to build new software (along with sensors, and of course, durable balloons). Bloomberg Businessweek reports: Since the Zinger, it's conducted more than 50 flights, primarily for the U.S. government, and kept its balloons up in the air for many days at a time. "People want us to do things like sit over the Red Sea and Indian Ocean and look for pirates," says Taber MacCallum, co-founder and chief technology officer. The company plans to start flying for commercial clients early next year. "Basically, our mission is to take over the stratosphere," he says.
Interestingly, Elon Musk also asked MacCallum's first company to design a greenhouse for Mars.

Skywatchers are being treated to the longest "blood moon" eclipse of the 21st Century. From a report: As it rises, during this total eclipse, Earth's natural satellite turns a striking shade of red or ruddy brown. The "totality" period, when light from the Moon is totally obscured, will last for one hour, 43 minutes. At least part of the eclipse is visible from Europe, the Middle East, Africa, Australia, most of Asia and South America. On the same night and over the coming days, Mars will be at its closest point to Earth since 2003 - visible as a "bright red star" where skies are clear. Here's a live feed, provided by NASA.

On July 27, the moon is set to glide through Earth's shadow to create a red total lunar eclipse for one hour and 43 minutes -- the longest such eclipse of the young century. Viewers in the United States will have to watch the eclipse online as they're on the wrong side of the world. "Folks in western Africa, part of Europe, the Middle East and India will only have to look up to the sky to catch the deep-copper-toned totality in person," reports The Washington Post. From the report: "What makes the upcoming one special is that it occurs at nearly the same time as the year's second-most-distant lunar apogee (the monthly moment when the moon is most distant from Earth) and the moon passes almost smack through the center of Earth's shadow," astronomer Geoff Chester of the Naval Observatory said. He continued: "This will make it the longest-duration total lunar eclipse of the century. It's also cool that [the eclipse] occurs on the night that Mars reaches opposition, so (for people on the other side of the world) you'll have a red moon six degrees north of the Red Planet." All eclipses belong to eclipse families called saros. In this case, this eclipse is part of Saros 139, and it is No. 38 in a family of 71 that started June 10, 1351. This saros will last until July 24, 2613, per NASA. While technically this will be the longest eclipse of the century, the two previous lunar eclipses in this series -- July 16, 2000 (No. 37, Saros 139) and July 6, 1982 (No. 36, Saros 139) -- lasted longer than this one. In fact, the July 16, 2000, lunar eclipse lasted about three minutes longer. But remember, astronomers count the year 2000 as part of the last century.

Throughout the Eastern time zone, according to NASA and the U.S. Naval Observatory, the lunar eclipse (penumbral phase) starts at 1:14 p.m. and partiality occurs at 2:24 p.m. Totality starts at 3:30 p.m., with the maximum totality at 4:21 p.m. Totality will end at 5:13 p.m., and the partial eclipse ends at 6:19 p.m. Everything is over by 7:28 p.m. Unfortunately, the moon will not have risen anywhere in the United States for viewing during this window. If you're not able to watch it locally, you can tune to the Weather Channel app, the website Slooh, or TimeandDate.com. The NBC News streaming network is also showing the eclipse at 4 p.m. on July 27.

For decades Mars has teased scientists with whispers of water's presence. Now they have some solid evidence. From a report: The Italian Space Agency announced Wednesday that researchers have detected signs of a large, stable body of liquid water locked away beneath a mile of ice near Mars' south pole. The observations were recorded by the Mars Advanced Radar for Subsurface and Ionosphere Sounding instrument -- Marsis for short. "Marsis was born to make this kind of discovery, and now it has," says Roberto Orosei, a radioastronomer at the National Institute for Astrophysics, who led the investigation. His team's findings, which appear in this week's issue of Science, raise tantalizing questions about the planet's geology -- and its potential for harboring life. CNN elaborates: Between May 2012 and December 2015, MARSIS was used to survey the Planum Australe region, which is in the southern ice cap of Mars. It sent radar pulses through the surface and polar ice caps and measured how the radio waves reflected back to Mars Express. Those pulses reflected 29 sets of radar samples that created a map of drastic change in signal almost a mile below the surface. It stretched about 12.5 miles across and looked very similar to lakes that are found beneath Greenland and Antarctic ice sheets on Earth. The radar reflected the feature's brightness, signaling that it's water. "We interpret this feature as a stable body of liquid water on Mars," the authors wrote in the study.

Scientists from Birkbeck, University of London speculate that recent results show that the moon is wetter than scientists have previously thought, increasing the possibility for it to have the necessary conditions for life. "Whether life ever arose on the Moon, or was transported to it from elsewhere, is of course highly speculative and can only be addressed by an aggressive future program of lunar exploration," they write in the article, published in the journal Astrobiology. Gizmodo summarizes: This habitability period, if it really occurred, might have happened either just after the Moon's formation from a massive collision with Earth 4.5 billion years ago, or 3.5 billion years ago, after a period of volcanism which may have resulted in a thin lunar atmosphere. Such an atmosphere would have lasted perhaps tens of millions of years. Maybe water existed on the Moon at this point. Maybe 10 million years was enough time for some rudimentary life to evolve on the Moon. Maybe Earthly life traveled over to the Moon on asteroids. Who knows.

The researchers stress that "habitability requires much more than just the presence of a significant atmosphere and liquid water." One such requirement would be the presence of organic compounds. And there are obviously not the same water-created features on the Moon that we see here on Earth or on Mars, like drainage channels -- though maybe these existed and were eroded by small meteors and solar winds. While the paper doesn't present new data, it's an interesting synthesis of lots of existing research demonstrating that, since the Moon is wetter than was initially thought, maybe it's worth wondering whether it was once habitable.

An anonymous reader shares a report: Inside a sealed clean room near Toulouse, France, Maurice Sylvestre points out something called SuperCam. Sylvestre is outfitted in Tyvex and hairnets, necessary to keep out dust, skin particles, and dirt that could mar the super-smooth surface of his device. SuperCam sits underneath a ventilator hood, glimmering inside a golden-metallic housing. The device is designed to scan the Martian surface with a camera, laser, and spectrometer in hopes of finding organic compounds that could be related to early life on Mars. In two years, this 12-pound, microwave oven-sized unit will blast off as part of the Mars 2020 mission, a spacecraft/lander/rover combo by NASA and its partners that will replace the long-serving Curiosity mission.

Sylvestre is a planetary scientist at France's Institute for Research and Planetary Astronomy, and deputy principal investigator for SuperCam. But he's an international collaborator: Over the years, he's worked on missions to Saturn, the moon, and Mars with NASA colleagues. Sylvestre's lab is currently building an instrument similar to SuperCam that will fly to Mercury on the European-Japanese BepiColombo mission, as well as one called Eclair that is part of a joint French-Chinese satellite. Notably, that makes him one of a small number of planetary scientists who are working with China to boost their science, while doing his best to keep Western technology from getting pilfered. It's a tightrope that not everyone is willing to walk. "We are careful what we are doing," Sylvestre says.

"We understand the security issues. We understand that we should be careful and not be too naive. But at the same time I feel the idea of planetary exploration is for everyone." Working with both NASA and China may seem like a contradiction, or even a conflict. The two superpowers are butting heads on trade, military, and cybersecurity issues. Congress has banned NASA officials and NASA money from going to China. That might be because of a recent history of Chinese espionage targeting US military, aerospace, and technological secrets.

An anonymous reader shares a report: Over 40 years ago, a NASA mission may have accidentally destroyed what would have been the first discovery of organic molecules on Mars, according to a report from New Scientist. Recently, NASA caused quite a commotion when it announced that its Curiosity rover discovered organic molecules -- which make up life as we know it -- on Mars. This followed the first confirmation of organic molecules on Mars in 2014. But because small, carbon-rich meteorites so frequently pelt the Red Planet, scientists have suspected for decades that organics exist on Mars.

But researchers were stunned in 1976, when NASA sent two Viking landers to Mars to search for organics for the first time and found absolutely none. Scientists didn't know what to make of the Viking findings -- how could there be no organics on Mars? "It was just completely unexpected and inconsistent with what we knew," Chris McKay, a planetary scientist at NASA's Ames Research Center, told New Scientist.

"The wealthy are plotting to leave us behind," writes Douglas Rushkoff, describing what he learned from a high-paying speaking gig about the future of technology for "five super-wealthy guys...from the upper echelon of the hedge fund world," -- and what it says about perceptions of technology today. The Event. That was their euphemism for the environmental collapse, social unrest, nuclear explosion, unstoppable virus, or Mr. Robot hack that takes everything down. This single question occupied us for the rest of the hour. They knew armed guards would be required to protect their compounds from the angry mobs. But how would they pay the guards once money was worthless? What would stop the guards from choosing their own leader...?

That's when it hit me: At least as far as these gentlemen were concerned, this was a talk about the future of technology. Taking their cue from Elon Musk colonizing Mars, Peter Thiel reversing the aging process, or Sam Altman and Ray Kurzweil uploading their minds into supercomputers, they were preparing for a digital future that had a whole lot less to do with making the world a better place than it did with transcending the human condition altogether and insulating themselves from a very real and present danger of climate change, rising sea levels, mass migrations, global pandemics, nativist panic, and resource depletion. For them, the future of technology is really about just one thing: escape.

There's nothing wrong with madly optimistic appraisals of how technology might benefit human society. But the current drive for a post-human utopia is something else. It's less a vision for the wholesale migration of humanity to a new state of being than a quest to transcend all that is human: the body, interdependence, compassion, vulnerability, and complexity.... It's a reduction of human evolution to a video game that someone wins by finding the escape hatch and then letting a few of his BFFs come along for the ride... The future became less a thing we create through our present-day choices or hopes for humankind than a predestined scenario we bet on with our venture capital but arrive at passively. This freed everyone from the moral implications of their activities... Ultimately, according to the technosolutionist orthodoxy, the human future climaxes by uploading our consciousness to a computer or, perhaps better, accepting that technology itself is our evolutionary successor.
The piece -- titled "Survival of the Richest" -- is an interesting read, and ends by suggesting this inspiring counter-philosophy.

"Being human is not about individual survival or escape. It's a team sport."

This week NASA's Dawn space probe swooped within 22 miles of the surface of Ceres, the dwarf planet that's the largest object in the asteroid belt between Mars and Jupiter. NASA's JPL reports: In more than three years of orbiting Ceres, Dawn's lowest altitude before this month was 240 miles (385 kilometers), so the data from this current orbit bring the dwarf planet into much sharper focus... "[T]he results are better than we had ever hoped," said Dawn's chief engineer and project manager, Marc Rayman, of NASA's Jet Propulsion Laboratory, Pasadena, California. "Dawn is like a master artist, adding rich details to the otherworldly beauty in its intimate portrait of Ceres."
EarthSky reports NASA captured an up-close glimpse of those tantalizing bright spots on Ceres: The spots, evaporate deposits composed of sodium carbonate, are thought to be left over from when water came up to the surface from deeper below and then evaporated in the extremely tenuous and sporadic water vapor "atmosphere." That water could be either from a shallow sub-surface reservoir or from a deeper reservoir of salty brines percolating upward through fractures. The deposits in Occator Crater are the largest and brightest of these deposits. As with many discoveries in planetary science, they were completely unexpected, and show that Ceres is not just an inert ball of rock and ice.
Slashdot reader thegameiam adds: Ceres may have more fresh water than exists on Earth. Perhaps this would make colonization of the asteroid belt more of a possibility?

The United States wants to send robotic explorers to the moon as soon as next year as a preparatory step toward sending astronauts back there for the first time since 1972, a NASA official said on Monday. From a report: The National Aeronautics and Space Administration is planning a series of lunar missions beginning next year aimed at developing the capacity for a return to the moon, said Cheryl Warner, a spokeswoman for NASA's Human Exploration Directorate. NASA will work with private companies, which have not yet been chosen, on the missions, Warner said in a phone interview. U.S. President Donald Trump in December signed a directive that he said would enable astronauts to return to the moon and eventually lead a mission to Mars. Last month he ordered the government to review regulations on commercial space flights.

According to NASA, the Mars Opportunity rover is currently trying to survive an intensifying dust storm on the red planet. "The storm's atmospheric opacity -- the veil of dust blowing around, which can blot out sunlight -- is now much worse than a 2007 storm that Opportunity weathered," reports NASA. "The previous storm had an opacity level, or tau, somewhere above 5.5; this new storm had an estimated tau of 10.8 as of Sunday morning." Engadget reports: The storm was first detected on Friday June 1st by the Mars Reconnaissance Orbiter, at which point the rover's team was notified because of the weather event's proximity to Opportunity. The rover uses solar panels, so a dust storm could have an extremely negative impact on Opportunity's power levels and its batteries. By Wednesday June 6th, Opportunity was in minimal operations mode because of sharply decreasing power levels. The brave little rover is continuing to weather the storm; it sent a transmission back to Earth Sunday morning, which is a good sign. It means there's still enough charge left in the batteries to communicate with home, despite the fact that the storm is continuing to worsen.
