LeadSongDog writes "Space.com is reporting on a 60km comet-like body in Lagrangian orbit around the Sun, locked to Uranus's leading Trojan Point. This means a distant, but fairly accessible supply of water-ice, hence: reaction mass, hydrogen and oxygen for robotic miners if we can just get them there with an energy source. 'The sun and Earth have two Trojan points, one leading ahead of Earth, known as the L-4 point of the system, and one trailing behind, its L-5 point. The sun and other planets have Lagrangian points also, with asteroids seen at those the sun shares with Jupiter, Neptune and Mars. Scientists thought the Trojan points of Uranus, the seventh planet from the sun, were too unstable to host asteroids."

Zothecula writes "NASA took the metaphorical training wheels off the Mars rover Curiosity on Tuesday, as the unmanned explorer took its first drive using autonomous navigation. It used its onboard cameras and software to select and drive over an area of ground that mission control at the Jet Propulsion Laboratory in Pasadena, California couldn't see and vet beforehand. This capability allows the nuclear-powered rover to negotiate the most direct route to Mount Sharp rather than having to detour to find routes that can be seen directly by Curiosity before entering, so they can be analyzed by mission control."

MarkWhittington writes "Neil deGrasse Tyson, the famous astrophysicist and media personality, offered something of a reality check on the potential of commercial enterprises to open the space frontier without the aid of government. Specifically referencing SpaceX's CEO Elon Musk's boast that he would establish a Mars colony, Tyson said on a recent video podcast, 'It's not possible. Space is dangerous. It's expensive. There are unquantified risks. Combine all of those under one umbrella; you cannot establish a free market capitalization of that enterprise.'"

coondoggie writes "Men are supposed to be from Mars as John Gray's iconic relationship book would have you think, but new research presented this week suggests that in reality; we all may hail from the Red Planet. 'The evidence seems to be building that we are actually all Martians; that life started on Mars and came to Earth on a rock. It's lucky that we ended up here nevertheless, as certainly Earth has been the better of the two planets for sustaining life. If our hypothetical Martian ancestors had remained on Mars, there might not have been a story to tell,' Professor Steven Benner of The Westheimer Institute for Science and Technology said."

An anonymous reader writes "Kickstarter's helped start all sorts of indie games, but few as unusual as Lacuna Passage, an adventure game set on Mars with a vast open world that's been painstakingly recreated from NASA satellite data. You're able to explore twenty five square miles of the Red Planet in all its barren glory as you attempt to solve the mystery of the first, vanished, manned mission to mars. A new piece today on the making of the game — which is being made by an elementary school teacher and a team of a dozen volunteers — looks at how it came about, and why their quest for authenticity led to even urine analysis being included in the gameplay."

After four months in a mock space habitat in Hawaii, participants in a study to determine how best to feed astronauts (HI-SEAS) on a mission to Mars emerged yesterday. A few days ago, the mission commander was interviewed in Astrobiology Magazine, noting the most successful foods: "There's also been a lot of really good cooked dishes. Some of our crew members are accomplished cooks, and every week there are different surprises. Some success meals were Russian borscht, Moroccan tagine, enchilasagna, seafood chowder, and fabada asturiana. Wraps work really well: we combine tortillas, different vegetables, Velveeta cheese, and sausage or canned fish into ever-changing combinations. This is actually in line with the success of tortillas at the ISS. In general, the dehydrated and freeze-dried vegetables are a real success. They're used on a daily basis in almost every meal." The crew kept weblogs, and did other things than just sit around and eat: some studied robotics and they went on a few simulated EVAs.

Bas Lansdorp's projected trip to Mars has a well-known catch: the ticket to space is free (rather than the millions of dollars for the more conventional kind of space travel available to civilians), but it's one-way only. That's a downside for any potential astronauts who'd like to do things like visit the beach or ever see their Earthside family again in person. Still, the Mars One project announced this week that more than 100,000 volunteers have announced their willingness to forsake this planet in favor of the next. The application process is ongoing; have you signed up?

Hugh Pickens DOT Com writes "Time Magazine reports that in and effort to involve non-rocket scientists in the next mission to the Red Planet, NASA invited the public in May to submit haiku, three line poems where 'the first and last lines must have exactly five syllables each and the middle line must have exactly seven syllables.' NASA promised to select five winners that will be adhered to the Mars Atmosphere and Volatile Evolution Mission (MAVEN) before it is launched towards Martian airspace. 'The Going to Mars campaign offers people worldwide a way to make a personal connection to space, space exploration, and science in general, and share in our excitement about the MAVEN mission,' said Stephanie Renfrow, lead for the MAVEN Education and Public Outreach program at CU/LASP. More than 15,000 entries were submitted by space geeks and poets the world over. A couple thousand were disqualified as too long, too short, or totally inappropriate, leaving about 12,500. The public voted online, and the five top vote-getters have been announced." The winner:

It's funny, they named
Mars after the God of War

First time accepted submitter Zoë Mintz writes "Researchers have 'resurrected' a 4-billion-year-old Precambrian protein and found they resembled those that existed when life began, proving that protein structures have the ability to remain constant over extended periods of time."

An anonymous reader writes "The Curiosity rover celebrates one year on Mars today. 'The 1-ton robot has achieved a great deal in its 12 months on Mars, discovering an ancient streambed and gathering enough evidence for mission scientists to declare that the planet could have supported microbial life billions of years ago. And more big finds could be in the offing, as Curiosity is now trekking toward its ultimate science destination: the foothills of a huge and mysterious mountain that preserves, in its many layers, a history of Mars' changing environmental conditions.'"

Velcroman1 writes "The group was down to Earth — but not for long, they hope. These folks want to go to Mars. 'I want off the planet – I want humanity off the planet,' declared Leila Zucker, 45, also known as 'Dr. Leila,' because she is, in fact, a doctor who works nearby in the emergency room at Howard University Hospital. She has yearned to be an astronaut — and a doctor — since the age of 3, she told FoxNews.com. 'One dream fulfilled, one to go,' she said happily. Zucker joined not a million, but 100 or so 'aspiring Martians' from across the country, one with green hair and costume antennae, for a 'Million Martian Meeting' held Saturday in Washington, D.C., which was sponsored by the Facebook page of the same name. The group came together as applicants of the Mars One project, an ambitious 10-year plan for a one-way trip to colonize the Red Planet."

Daniel_Stuckey writes "Like so many great leaps for mankind, getting a human to one of Jupiter's moons must begin with a small step. And Objective Europa is aiming to do exactly that. A small team — architects, futurist designers, private space pioneers and even Jacques Cousteau's son — is beginning the planning stage to send human beings on a one-way trip to the Jovian moon Europa. The effort is headed up by Kristian Von Bengston, the founder of Copenhagen Suborbitals, an open source DIY space program based in his native Denmark. And he's quite serious about transporting a man or woman beyond our atmosphere, Mars and the asteroid belt."

SchrodingerZ writes "Planetary Geologist Ellen Stofan, expert in the terrains of Venus, Mars, and Titan, has recently been appointed the Chief Scientist for the space agency. Stofan will act as the top adviser for Charles Bolden, NASA's current administrator. Beginning August 25th, Stofan will be Bolden's head adviser for NASA's project planning and investments. She will replace former chief scientist Dr. Waleed Abdalati, who left his position to be the director of the Cooperative Institute for Research in Environmental Sciences at the University of Colorado. Stofan has both a masters and doctoral degree of geological sciences from Brown University, and is known for her involvement in the Applied Science Laboratory's project to put a boat on Saturn's moon Titan, as well as a member of the radar team for the Cassini spacecraft. Though she'll be joining in a time of large budget cuts, Bolden explains that '[Stofan's] breadth of experience and familiarity with the agency will allow her to hit the ground running. We're fortunate to have her on our team.'"

gbrumfiel writes "Researchers in France have discovered the world's largest virus and given it a terrifying name: Pandoravirus. NPR reports it doesn't pose a threat to people, but its genetic code could hint at an unusual origin. The team believes that the virus may carry the genes from a long-dead branch of the tree of life, one that possibly even started on Mars or somewhere else. Other scientists are skeptical, but everyone agrees that the new giant virus is pretty cool."

astroengine writes "At one time, Mars had a thick, protective atmosphere — possibly even cushier than Earth's — but the bubble of gases mostly dissipated about 4 billion years ago and has never been replenished, new research shows. The findings come from NASA's Mars rover Curiosity, which has been moonlighting as an atmospheric probe as it scours planet's surface for habitats that could have supported ancient microbial life. 'On Earth, our magnetic field protects us, it shields us from the solar wind particles. Without Earth's magnetic field, we would have no atmosphere and there would be no life on this planet. Everything would be wiped out — especially when you go back 4 billion years. The solar wind was at least 100 times stronger then than it is today. It was a young sun with a very intense radiation,' Chris Webster, manager of the Planetary Sciences Instruments Office at NASA's Jet Propulsion Laboratory in Pasadena, Calif., told Discovery News. Unfortunately for Mars, the last 4 billion years have not been kind."

astroengine writes "With the help of rover Curiosity, we now know that ancient Mars had large quantities of liquid water flowing across its surface. However, evidence for large bodies of water — i.e. seas/oceans — has been hard to come by. But using high-resolution orbital data, Caltech scientists now think they've found a long-dry river delta that once flowed into a very large body of water. Welcome to the Aeolis Riviera — the strongest evidence yet for a Martian coastline. "This is probably one of the most convincing pieces of evidence of a delta in an unconfined region — and a delta points to the existence of a large body of water in the northern hemisphere of Mars," said Roman DiBiase, Caltech postdoctoral scholar and lead author of the paper that was published (abstract) in the Journal of Geophysical Research."

coondoggie writes "The space missions to Mars have so far been one way — satellites and robotic rovers have all gone there to stay. NASA, as part a of a new, ambitious Mars visit, wants to change that by sending a rover to the surface of the Red Planet which can dig up chunks of the surface and send them back to Earth for highly detailed examination. These plans were laid out in a lengthy report outlining mission plans for Mars that will be acted upon over the next decade. It says a retrieval mission 'could occur as early as the mid-2020s or wait until the 2030s.'"

An anonymous reader writes "This movie clip shows Phobos, the larger of the two moons of Mars, passing overhead, as observed by NASA's Mars rover Curiosity in a series of images centered straight overhead starting shortly after sunset. Phobos first appears near the lower center of the view and moves toward the top of the view. The clip runs at accelerated speed; the amount of time covered in it is about 27 minutes"

An anonymous reader writes "Sixteen years ago, the Mars Pathfinder lander touched down on Mars and began collecting about the atmosphere and geology of the Red Planet. Its original mission was planned to last somewhere between a week and a month, but it only took a few days for software problems to crop up. The engineers responsible for the system were forced to diagnose the problem and issue a patch for a device that was millions of miles away. From the article: 'The Pathfinder's applications were scheduled by the VxWorks RTOS. Since VxWorks provides pre-emptive priority scheduling of threads, tasks were executed as threads with priorities determined by their relative urgency. The meteorological data gathering task ran as an infrequent, low priority thread, and used the information bus synchronized with mutual exclusion locks (mutexes). Other higher priority threads took precedence when necessary, including a very high priority bus management task, which also accessed the bus with mutexes. Unfortunately in this case, a long-running communications task, having higher priority than the meteorological task, but lower than the bus management task, prevented it from running. Soon, a watchdog timer noticed that the bus management task had not been executed for some time, concluded that something had gone wrong, and ordered a total system reset.'"

cold fjord writes "This might be useful. From CNN: 'Recent evidence from NASA's Curiosity rover mission to the Red Planet has revealed that astronauts on the round-trip would be exposed to high levels of radiation from cosmic rays and high-energy particles from the sun ... this would clearly be bad for your health — and it is proving difficult to find a solution. ... [S]hielding to completely block the radiation danger would have to be "meters thick" and too heavy to be used aboard a spacecraft. In contrast, ... science fiction fans have once again got used to the ease with which Captain Kirk gives the order for "shields up" and the crew of the Enterprise being protected instantly from the hostility of space. Perhaps though, a real Star Trek shield may no longer be science fiction — scientists at the UK's Rutherford Appleton Laboratory (RAL) certainly think so. They have been testing a lightweight system to protect astronauts and spacecraft components from harmful radiation and working with colleagues in America to design a concept spaceship called Discovery that could take astronauts to the Moon or Mars. "Star Trek has great ideas — they just don't have to build it," said Ruth Bamford, lead researcher for the deflector shield project at RAL. ... The RAL plan is to create an environment around the spacecraft that mimics the Earth's magnetic field and recreates the protection we enjoy on the ground — they call it a mini magnetosphere."
