Calopteryx writes "New Scientist reports that in 2005, researchers predicted two potential signatures of life on Titan. Now, thanks to research done with the help of the Cassini spacecraft, both have been seen, although non-biological chemical reactions could also be behind the observations. NASA's writeup has further details: 'One key finding comes from a paper online now in the journal Icarus [abstract] that shows hydrogen molecules flowing down through Titan's atmosphere and disappearing at the surface. Another paper online now in the Journal of Geophysical Research maps hydrocarbons on the Titan surface and finds a lack of acetylene. This lack of acetylene is important because that chemical would likely be the best energy source for a methane-based life on Titan, said Chris McKay, an astrobiologist at NASA Ames Research Center, Moffett Field, Calif., who proposed a set of conditions necessary for this kind of methane-based life on Titan in 2005. One interpretation of the acetylene data is that the hydrocarbon is being consumed as food. But McKay said the flow of hydrogen is even more critical because all of their proposed mechanisms involved the consumption of hydrogen.'"

saintory writes "Shuttle Atlantis landed this morning after flying its final official mission. In its 25-year service, the shuttle Atlantis has logged over 120 million miles." After a successful mission to deliver a research module to the International Space Station, the craft landed at Kennedy Space Center, and will "go through the normal flow of prelaunch preparations in order to serve as the 'launch-on-need' vehicle for Endeavour's STS-134 mission, the last scheduled flight of the Space Shuttle Program." Congratulations to the people aboard and on the ground who engineered the shuttle's successful return.

coondoggie writes "NASA officially ended its Phoenix Mars Lander operation today after a new image of the machine showed severe ice damage to its solar panels, and repeated attempts to contact the spacecraft had failed. 'Apparent changes in the shadows cast by the lander are consistent with predictions of how Phoenix could be damaged by harsh winter conditions. It was anticipated that the weight of a carbon-dioxide ice buildup could bend or break the lander's solar panels. [Michael Mellon of the University of Colorado] calculated hundreds of pounds of ice probably coated the lander in mid-winter.'"

s31523 writes "The Mars rover Opportunity has beaten the original record of six years and 116 days operating on the surface of Mars, originally set by the Viking 1 Lander. While the Spirit rover has been on the surface longer than the Opportunity by three weeks, it has been out of communication since March 22. If Spirit comes back online, it will attain the new Martian surface longevity record. This feat, right on the heels of another longevity feat (Voyager 2 and twin on the verge of entering interstellar space and still kicking) is healing some of NASA's past black eyes. It is quite remarkable given original spec of 90 days for the mission. With the passing of the solstice, warmer temperatures and more sun will likely mean the rover will continue on."

shuz writes "Space shuttle Atlantis lifted off today on its STS-132 mission to the International Space Station — the final flight for the venerable vehicle. The mission involves three spacewalks over 12 days (PDF), during which the team will replace six batteries on the port truss which store energy from solar panels on that truss, bolt on a spare space-to-ground Ku-band antenna, and attach a new tool platform to Canada's Dextre robotic arm." NASA has video of the historic launch and reader janek78 adds this quote from the mission summary: "Atlantis lifted off on its maiden voyage on Oct. 3, 1985, on mission 51-J. Later missions included the launch of the Magellan probe to Venus on STS-30 in May 1989, Galileo interplanetary probe to Jupiter on STS-34 in October 1989, the first shuttle docking to the Mir Space Station on STS-71 in June1995, and the final Hubble servicing mission on STS-125 in May 2009."

FleaPlus writes "NASA has released the initial details on its ETDD (Enabling Technology Development and Demonstrations) program to 'develop and demonstrate the technologies needed to reduce cost and expand the capability of future space exploration activities.' The ETDD program is initially planning on funding small-scale demonstrations in five technology areas: in-situ resource utilization (with a robotic lunar resource extraction mission in 2015), high-power electric propulsion, autonomous precision landing (building on the success of the Lunar Lander Challenge), human-robotic collaboration (2011/2012), and fission power systems. More info on NASA's larger-scale Flagship Technology Demonstrations (FTD) program is expected in the coming month."

Hugh Pickens sends in coverage in the Telegraph of a joint NASA-ESA experimental mission, to launch around 2020. It involves three spacecraft orbiting the Sun, separated by 3 million miles, each with a payload of two lasers and a 4.6-cm cube of gold-platinum alloy. The point of it all is to look for gravitational waves. The mission is called LISA, a reasonably non-strained acronym for Laser Interferometer Space Antenna. The Telegraph makes a point of LISA being the largest experiment ever constructed (in terms of its dimensions). Neither that newspaper nor the project page at NASA mentions how much the experiment will cost, but it's almost certainly an order of magnitude or more above the $66 million estimated for a gravitational wave detector the size of the galaxy, which we discussed last fall.

CWmike writes "Imagine a team of robots — some rolling on wheels, some walking on two legs — working alongside astronauts on the surface of Mars, scouting previously unseen locations, measuring the parameters of a new base or constructing a building. Now picture astronauts driving across the Martian surface in a vehicle. When the astronauts get out and begin their work, they can flip a switch to turn the vehicle into an autonomous robot that goes off to undertake projects on the planet. Whatever work the next generation of NASA-developed space robots does, it will be done in conjunction with their human counterparts. Terry Fong, director of NASA's intelligent robotics group, said that's the image that a lot of the US space agency's engineers have in mind as they work on the new robotic rovers. In comparison, the Mars rovers on the Red Planet have been working alone for years. 'We're working on a new use of these robots — robots to support human exploration,' Fong said. 'NASA is now thinking, "How do you go about sending humans to the moon or Mars or elsewhere? How can you use the combination of humans and robots to do exploration better?" I think it's a really, really fundamentally different approach.' Fong said he's hopeful that the next-generation robotic rovers will arrive on the moon or on an asteroid within five to 10 years."

FleaPlus writes "Water ice was recently discovered on the large asteroid 24 Themis, and Space.com discusses proposals for producing fuel from asteroid ice. NASA and the President recently announced plans for robotic precursor missions to asteroids (and a human mission by 2025), as well as a funding boost for R&D to develop techniques like in-situ resource utilization. Since most of the mass of a beyond-Earth mission is fuel, refueling in orbit would be a huge mass- and cost-saver for space exploration (especially if fuel can be produced in space), but a large unknown is how to effectively extract water in an environment lacking gravity."

PSandusky writes "NASA is preparing to make use of Aquarius, the underwater laboratory off Key Largo, for an extended period of time to research the effects of isolation in habitats situated in extreme environments. Planned areas of research include extravehicular activity logistics and crew health and performance. According to NASA's factsheet (PDF), the mission will include some communication with schools and social media sites. "

@10u8 writes "The Vatican Library plans to digtize 80,000 manuscripts and store them in the open data format FITS, originally developed for astronomy and maintained under the IAU. The result is expected to be 40 million pages and 45 petabytes. FITS was chosen because it 'has been used for more than 40 years for the conservation of data concerning spatial missions and, in the past decade, in astrophysics and nuclear medicine. It permits the conservation of images with neither technical nor financial problems in the future, since it is systematically updated by the international scientific community.'"

coondoggie writes "NASA is looking for a few good experiments to run in space. The space agency this week said it was seeking research ideas (PDF) from private entities who want to do research on board the International Space Station. NASA said it was looking to expand the use of the ISS by providing access to the lab for the conduct of basic and applied research, technology development, and industrial processing to private entities — including commercial firms, non-profit institutions, and academic institutions. NASA said using the ISS as a national lab could help develop a number of applications in areas such as biotechnology, energy, engineering, and remote sensing."

NASA released some of the most spectacular photos for the event."

TheOtherChimeraTwin notes that the shuttle Discovery will land at Kennedy Space Center on Monday morning at 8:48 EDT. The craft will make a rare "descending node" overflight of the continental US en route to landing in Florida. Here are maps of the shuttle's path if is lands on orbit 222 as planned, or on the next orbit. Spaceweather.com says: "...it takes the shuttle about 35 minutes to traverse the path shown... Observers in the northwestern USA will see the shuttle shortly after 5 am PDT blazing like a meteoric fireball through the dawn sky. As Discovery makes its way east, it will enter daylight and fade into the bright blue background. If you can't see the shuttle, however, you might be able to hear it. The shuttle produces a sonic double-boom that reaches the ground about a minute and a half after passing overhead."

separsons writes "A team of scientists recently created the world's first underwater robotic vehicle powered entirely by renewable ocean thermal energy. Researchers from NASA, the Scripps Institution of Oceanography and the US Navy developed Sounding Oceanographic Lagrangrian Observer Thermal RECharging (SOLO-TREC), an autonomous robot that runs on a thermal recharging engine. The engine derives power from the natural temperature differences found at varying ocean depths. SOLO-TREC produces about 1.7 watts of power each dive, enough to juice the robot's science instruments, GPS receiver, communication device, and buoyancy control pump. SOLO-TREC is poised to revolutionize ocean monitoring; previous robots could spend only a limited amount of time underwater because of depleting power sources. SOLO-TREC can stay beneath the surface of the waves for indefinite amounts of time. Based on SOLO-TREC's success, NASA and the US Navy plan to incorporate thermal recharging engines in next-generation submersibles."

PipianJ writes "A recent preprint posted on arXiv by Vadim Bobylev presents some startling new numbers about a future close pass of one of our stellar neighbors. Based on studies of the Hipparcos catalog, Bobylev suggests that the nearby orange dwarf Gliese 710 has an 86% chance of skirting the outer bounds of the Solar System and the hypothesized Oort Cloud in the next 1.5 million years. As the Oort Cloud is thought to be the source of many long-period comets, the gravitational effects of Gliese's passing could send a shower of comets into the inner Solar System, threatening Earth. This news about Gliese 710 isn't exactly new, but it's one of the first times the probability of this near-miss has been quantified."

Hugh Pickens writes "BBC reports that Royal Observatory's 'Solar Stormwatch' needs volunteers to help scientists spot Sun storms — known as coronal mass ejections — before they cause damage on Earth. 'When you look up at the Sun obviously it's too bright to look at properly,' says Dr. Marek Kukula of the Royal Observatory, but 'with special instruments and telescopes you can see there's all sorts of stuff going on.' NASA already monitors the Sun using two 'STEREO' spacecraft that produce 3D images of earth's nearest star, which can show the trajectory of these explosions. However, the sheer amount of data means NASA's scientists are unable to analyze the data as closely as they need — which is where the world's Internet population comes in. After a brief tutorial, users get access to the actual 3-D images taken by the STEREO spacecraft. If a user believes they have spotted the beginnings of a solar storm, they can bring it to the attention of scientists. 'Every little bit counts,' says Kukula. 'I've spoken to the scientists involved and they all agree that even if you log-on and just do it for a few hours, get bored and never touch it again it's all really useful — and helps them to do their work.'"

After analyzing data from a radar device aboard last year's Indian Chandrayaan-1 mission to the Moon, NASA scientists have found what they estimate to be 600 million metric tons of water ice in craters around the Moon's north pole. "Numerous craters near the poles of the Moon have interiors that are in permanent sun shadow. These areas are very cold and water ice is stable there essentially indefinitely. Fresh craters show high degrees of surface roughness (high circular polarization ratio) both inside and outside the crater rim, caused by sharp rocks and block fields that are distributed over the entire crater area. However, Mini-SAR has found craters near the north pole that have high CPR inside, but not outside their rims. This relation suggests that the high CPR is not caused by roughness, but by some material that is restricted within the interiors of these craters. We interpret this relation as consistent with water ice present in these craters. The ice must be relatively pure and at least a couple of meters thick to give this signature."

Hugh Pickens writes "NPR reports that toward the end of the summer of 1977, NASA launched two Voyager spacecraft that each included a golden record containing, among other things, the sound of a kiss, a mother's first words to her newborn child, music from all over the world, and greetings in 59 different languages. The records on board were meant to survive for a billion years, in the hope that some day, against enormous odds, they might cross paths with an alien civilization. The record was a special project of Carl Sagan with the help of Ann Druyan, creative director of the project. For Druyan, though, the summer of 1977 and the Voyager project carry a deeply personal meaning because it was during the Voyager project that she and Sagan fell in love. Then Druyan had an idea for the record: They could measure the electrical impulses of a human brain and nervous system, turn it into sound, and put it on the record so that maybe, 1,000 million years from now, some alien civilization might be able to turn that data back into thoughts." (More, below.) "Just a few days after she and Sagan declared their love for each other, Druyan went to Bellevue Hospital in New York City and meditated while the sounds of her brain and body were recorded. According to Druyan, part of what she was thinking during that meditation was about 'the wonder of love, of being in love.' And the gold records? They're still out there with their offer, to whomever might stumble across them, of a human body newly in love. 'Whenever I'm down, ' says Druyan, 'I'm thinking: And still they move, 35,000 miles an hour, leaving our solar system for the great open sea of interstellar space.'"

cyclone96 writes "Internet access on the International Space Station went live this morning. The crew now has full browsing capability via a special LAN and the Ku-band data link on the Tracking and Data Relay Satellite network, as described in the NASA press release. Flight Engineer T. J. Creamer used the access to post the first tweet from orbit about 7 hours ago. Previous astronaut tweets had been posted by a third party on the ground via email."

coondoggie writes "NASA says it is narrowing a short list of things its scientists can do to extricate its stuck Mars Spirit rover. They are exploring a couple remaining options, such as driving backwards and using Spirit's robotic arm to sculpt the ground directly in front of the left-front wheel, the only working wheel the arm can reach. The amount of energy that Spirit harvests each day, however, is declining, as autumn days shorten on southern Mars. 'At the current rate of dust accumulation, solar arrays at zero tilt would provide barely enough energy to run the survival heaters through the Mars winter solstice.' NASA is currently analyzing results of a Jan. 13th attempt to move the spacecraft that involved a very slow rotation of the wheels. Earlier drives in the past two weeks using wheel wiggles and slow wheel rotation produced negligible progress toward extricating Spirit, NASA stated."

coondoggie writes "NASA's Mars Odyssey orbiter will next week make a number of passes over the presumed dead Phoenix Mars Lander on the surface of the planet and listen for what the space agency called possible, though improbable, radio transmissions. Odyssey will pass over the Phoenix landing site about 10 times this month and two longer listening tries in February and March trying to determine if the craft survived Martian winter and try to lock onto a signal and gain information about the lander’s status."

Arvisp was one of several readers to send news of five new exoplanets discovered by the Kepler space telescope. In addition to the new "hot Jupiters" — the easiest targets to find — Kepler's early data has turned up some oddities, including something that is too hot to be a planet and too small to be a star. And one of the exoplanets is so fluffy that "it has the density of Styrofoam." The real news is that Kepler works as designed, and the scientists running it are fully confident that it will find Earth-like planets in some star's habitable zone, if they are out there to be found. Here is NASA's press release.

News of the upcoming NASA MMO, Astronaut: Moon, Mars, and Beyond, has been scarce since its announcement in 2008, but NASA recently revealed that a "mini demo game" is coming in January that will show off some of what they've completed so far. "Moon Base Alpha utilizes actual NASA Constellation program design details developed by NASA for mankind’s return to the Moon in 2020. Timelines in the much anticipated Astronaut: Moon, Mars and Beyond MMO will be set even farther in the exciting future (2035+), but the ability to explore our own near-future moon missions is also planned for in the forthcoming game facilitated by the NASA Learning Technologies and Innovative Partnerships Programs." They're provided a slideshow and a brief video, and one of the developers spoke about the game with Edge last month.

The Bad Astronomer writes "NASA's Cassini spacecraft took an image of Saturn's giant moon Titan earlier this year that serendipitously provides proof of liquid (probably methane) on its surface. The picture shows a glint of reflected sunlight off of a monster lake called Kraken Mare (larger than the Caspian Sea!). Scientists have been getting better and better evidence of liquid methane on Titan, but this is the first direct proof."

TopSpin writes "NASA's Constellation Program and Ares rockets appear to have strong support in Congress. An appropriations bill passed by the House includes language that bars 'any efforts by NASA to cancel or change the current Constellation program without first seeking approval of Congress.' The Administration's appointed NASA leadership is being publicly hostile towards its traditional aerospace affiliations. As Charles Bolden put it to industry execs, 'We are going to be fighting and fussing over the coming year,' and 'Some of you are not going to like me because we are not going to do the same kind of things we've always done.'"

The new video reveals changes in Saturn's aurora every few minutes, in high resolution, with three dimensions. The images show a previously unseen vertical profile to the auroras, which ripple in the video like tall curtains. These curtains reach more than 1,200 kilometers (750 miles) above the edge of the planet's northern hemisphere."

STEREO A and B orbit 90 degrees apart and luckily, one was overhead while the other saw the eruption on the limb. This gave NASA scientists enough data to confirm the tsunami wasn't a shadow, solving a modern solar mystery. The images are simply stunning, to boot."

coondoggie writes "NASA's long-running Mars rover Spirit is stuck in a sand trap — a situation the space agency would like to fix. Yesterday NASA said it will begin what it called the long process of extricating Spirit by sending commands that could free the rover. Spirit has been stuck in a place NASA calls 'Troy' since April 23, when the rover's wheels broke through a crust on the surface that was covering bright-toned, slippery sand underneath. After a few drive attempts to get Spirit out in the subsequent days, it began sinking deeper in the sand trap. Driving was suspended to allow time for tests and reviews of possible escape strategies, NASA stated."

PBH submitted a link to a really amazing composite image of the Milky Way released by NASA. They combined infrared, visible, and x-ray images taken by Spitzer, Hubble, and Chandra to create one beautiful image to commemorate the 400 years since 1609, when Galileo looked up.

Dagondanum writes "Multiple missions have been sent to Mars with the hopes of testing the surface of the planet for life — or the conditions that could create life. The question of whether life in the form of bacteria (or something even more exotic) exists on Mars is hotly debated, and still lacks a definitive yes or no. Experiments done right here on Earth that simulate the conditions on Mars and their effects on terrestrial bacteria show that it is entirely possible for certain strains of bacteria to weather the harsh environment of Mars." Perhaps this is something that will be tested further in a few years by the Mars Science Lab, also known as "Curiosity" and (as reader Nova1021 points out) "the Mars Action Hero."

avishere writes "Student teams designed and built robotic power-lifters to excavate simulated lunar soil (a.k.a. 'regolith') earlier this month, with $750,000 in prizes up for grabs. Excavating regolith, according to NASA, will be an important part of any construction projects or processing of natural resources on the Moon. Interestingly, regolith is especially difficult to dig because its dust particles want to stick together. The whole robotic system has to be sturdy enough to scoop moon dirt and powerful enough to move through the dust while still meeting the weight requirements. The winning excavator, from Worcester Polytechnic Institute in Massachusetts, lifted 1,103 pounds within the allotted time, and got its creators a sweet $500,000 for their troubles."

An anonymous reader sends along this excerpt from Nature News: "Kepler, NASA's mission to search for planets around other stars, will not be able to spot an Earth-sized planet until 2011, according to the mission's team. The delays are caused by noisy amplifiers in the telescope's electronics. ... The problem is caused by amplifiers that boost the signals from the charge-coupled devices that form the heart of the 0.95-metre telescope's 95-million-pixel photometer, which detects the light emitted from the distant stars. Three of the amplifiers are creating noise that compromises Kepler's view. The noise affects only a small portion of the data, Borucki says, but the team has to fix the software — it would be 'too cumbersome' to remove the bad data manually — so that it accounts for the noise automatically. He says that the fix should be in place by 2011." Mindful of Halloween's approach, NASA has put up a piece looking at some of the already-known exoplanets that wouldn't be very friendly to human life.

Ponca City, We love you writes "The NY Times reports that after a journey of 7.3 billion light-years, a race between gamma rays ranging from 31 billion electron volts to 10,000 electron volts, a factor of more than a million, in a burst from an exploding star, have arrived within nine-tenths of a second of each other. A detector on NASA’s Fermi Gamma-Ray Space Telescope confirmed Einstein’s proclamation in his 1905 theory of relativity that the speed of light is constant and independent of its color, energy, direction or how you yourself are moving. Some theorists had suggested that space on very small scales has a granular structure that would speed some light waves faster than others — in short, that relativity could break down on the smallest scales. Until now such quantum gravity theories have been untestable because ordinarily you would have to see details as small as the so-called Planck length, which is vastly smaller than an atom — to test these theories in order to discern the bumpiness of space."

The short test flight — about 2 minutes — will provide NASA an early opportunity to look at hardware, models, facilities and ground operations associated with the mostly new Ares I launch vehicle. The mission went off without a hitch — 'frickin' fantastic' was how one NASA executive classified it on NASA TV — as the upper stage simulator and first stage separated at approximately 130,000 feet over the Atlantic Ocean. The unpowered simulator splashed down in the ocean."
