We Finally Know What Happened to Water on Mars. Liquid Water on Mars. Nasa scientists find evidence of flowing water on Mars | Science. Liquid water runs down canyons and crater walls over the summer months on Mars, according to researchers who say the discovery raises the chances of being home to some form of life. The trickles leave long, dark stains on the Martian terrain that can reach hundreds of metres downhill in the warmer months, before they dry up in the autumn as surface temperatures drop. Images taken from the Mars orbit show cliffs, and the steep walls of valleys and craters, streaked with summertime flows that in the most active spots combine to form intricate fan-like patterns. Scientists are unsure where the water comes from, but it may rise up from underground ice or salty aquifers, or condense out of the thin Martian atmosphere.

“There is liquid water today on the surface of Mars,” Michael Meyer, the lead scientist on Nasa’s Mars exploration programme, told the Guardian. “Because of this, we suspect that it is at least possible to have a habitable environment today.” Here Are All the Best Photos from India's Mars Mission.

Steven Oleson NASA Glenn Research Center Description Phase II of the Titan Submarine: Exploring the Kraken Mare effort will focus on advancing the Technology Readiness Level (TRL) of the concept by (1) retiring risks found in the Phase I design, (2) gathering new Kraken Sea observations by Cassini, and (3) further defining science goals and instruments to fulfill them; each of these tasks will feed into two COMPASS design sessions. All of these products should ready the Titan Submarine (Titan Sub) concept to a confidence level that allow further NASA investment. The major risks found in the Phase I conceptual design center around vehicle operations in a liquid hydrocarbon sea. Basic physics questions of operating in this cryogen need to be answered. Cryogenic experts at the NASA Glenn Research Center will develop models to explore mixtures and pressures of cryogens and gases and how they would react with a warm submarine.

7 Innovative Concepts are Getting Closer to Reality Thanks to NASA. NASA Spacecraft Detects Impact Glass on Surface of Mars. HOUSTON - After an extensive year-and-a-half search, NASA has a new group of potential astronauts who will help the agency push the boundaries of exploration and travel to new destinations in the solar system, including an asteroid and Mars. Eight candidates have been selected to be NASA's newest astronaut trainees, hoping to be among those who are the first to launch from U.S. soil on commercial American spacecraft since the retirement of the space shuttle.

The 2013 astronaut candidate class comes from the second largest number of applications NASA has received - more than 6,000. Half of the selectees are women, making this the highest percentage of female astronaut candidates ever selected for a class. The group will receive a wide array of technical training at space centers and remote locations around the globe to prepare for missions to low-Earth orbit, an asteroid and Mars. NASA will discuss the selections at 3 p.m. The astronaut candidates are: Josh A.

[!] xkcd 1446. Touchdown! Rosetta’s Philae probe lands on comet / Rosetta. Farewell Philae - narrow-angle view Touchdown! Rosetta’s Philae probe lands on comet 12 November 2014 ESA’s Rosetta mission has soft-landed its Philae probe on a comet, the first time in history that such an extraordinary feat has been achieved. After a tense wait during the seven-hour descent to the surface of Comet 67P/Churyumov–Gerasimenko, the signal confirming the successful touchdown arrived on Earth at 16:03 GMT (17:03 CET). The confirmation was relayed via the Rosetta orbiter to Earth and picked up simultaneously by ESA’s ground station in Malargüe, Argentina and NASA’s station in Madrid, Spain. The first data from the lander’s instruments were transmitted to the Philae Science, Operations and Navigation Centre at France’s CNES space agency in Toulouse.

JUICE mission gets green light for next stage of development. 27 November 2014 The European Space Agency's JUICE (JUpiter ICy moons Explorer) mission has been given the green light to proceed to the next stage of development.

This approval is a milestone for the mission, which aims to launch in 2022 to explore Jupiter and its potentially habitable icy moons. JUICE gained approval for its implementation phase from ESA’s Science Programme Committee during a meeting at the European Space Astronomy Centre near Madrid, Spain, on 19 and 20 November 2014. Chosen by ESA in May 2012 to be the first large mission within the Cosmic Vision Programme, JUICE is planned to be launched in 2022 and to reach Jupiter in 2030. The scientific goals of the mission are enabled by its instrument suite. At the November 2014 meeting of the SPC, the multilateral agreement for JUICE was also approved. A Change In Congress Has Increased The Chances Of A Europa Mission. I really like the fact that he's supporting a mission to Europa. I just wish he weren't so insistent that we will find life if we go there.

Such a statement might help to get the mission funded, but if we don't find anything there, or we only find microbial life, the general public probably won't be so willing to support future mission. Most people don't understand the importance of knowledge for knowledge's sake. For example, I've had to explain to several people that despite the short lifespan of the Philae lander, it was still an amazing accomplishment, and is going to provide an enormous amount of new data that could eventually lead to new technologies and techniques that may, in turn, lead to even more. Most people stop listening when they hear that the mission wasn't perfect, and conclude that it was a waste. Lots of very vocal, very dedicated voters are already inherently distrustful of science.

Mars Rover Curiosity Drills into Mount Sharp. In its continuing mission to fathom whether Mars’ ancient environment may have been suitable to host microbial life, NASA’s Mars rover Curiosity once again dusted off its drill piece and, for the first time, bored into a rock at the base of Mount Sharp — a 3.5 mile high mountain in the center of Gale Crater also known as Aeolis Mons.

PHOTOS: Curiosity Snaps Selfies, Begins Mars Rock Drill Curiosity is currently located at the “Pahrump Hills” outcrop at the mountain’s base and mission scientists are excited by this new phase of the mission as samples collected from Mount Sharp will also help us understand how the mountain formed. “This drilling target is at the lowest part of the base layer of the mountain, and from here we plan to examine the higher, younger layers exposed in the nearby hills,” said Curiosity Deputy Project Scientist Ashwin Vasavada of NASA’s Jet Propulsion Laboratory in Pasadena, Calif.

The Curiosity Rover Has Arrived At Its Primary Scientific Target! NASA's Planned Missions. Keeping in Touch with Our Space Explorers. NASA wants to send a quadcopter to Saturn’s giant moon Titan. Saturn’s largest moon Titan fascinates the scientists at NASA due to its dense atmosphere and the presence of stable bodies of surface liquid alongside ice and rock. The nitrogen rich atmosphere experiences wind and rain, meaning the mix has produced a moon with similar features to Earth’s own surface, complete with rivers, lakes and seas (of liquid methane or ethane), mountains, and dunes.

Such an interesting place deserves to be explored, but visiting Titan for an extended period of time hasn’t been feasible due to a lack of supporting technology. NASA’s ideal vehicle for exploration there would be a helicopter, able to move quickly from place-to-place taking photos and collecting samples. But such a craft would be too expensive to develop and deploy, we haven’t had the tech to make it work autonomously, and even then you wouldn’t be able to support it.

Other missions including a balloon, plane, and boat have also been proposed and later shelved. NASA Has Recovered 7 "Precious" Particles From The Solar System's Birth. Seven precious particles, you say? SExpand Did they, by any chance, originate from here: Because if so, someone wants them back:

New Tool Coming In Hunt For Alien Life. With the James Webb Space Telescope still more than four years away from launch astronomers are coming up with ideas on how to maximise its usefulness. A proposal published in Astrobiology outlines a way it could be used to detect signatures of life on planets around nearby stars. While it is always possible that life around extrasolar worlds will be “not as we know it”, the obvious place to start looking is on planets as similar as possible to our own.

This includes the presence of liquid water, which in turn requires a substantial atmosphere. Low atmospheric pressure means water boils as soon as it melts. However, according to the new paper, “Current proposed methods for measuring pressure by using remote-sensing techniques that could be applicable to exoplanetary atmospheres are challenging.” A better way, the authors suggest, is to look for dimers. While knowing the pressure in the atmosphere is important, just picking up O2-O2 dimers could matter for another reason.

Mars Reconnaissance Orbiter: Overview. NASA's Mars Reconnaissance Orbiter blasted off from Cape Canaveral in 2005, on a search for evidence that water persisted on the surface of Mars for a long period of time. While other Mars missions have shown that water flowed across the surface in Mars' history, it remains a mystery whether water was ever around long enough to provide a habitat for life. Mars Reconnaissance Orbiter is studying the history of water on Mars After a seven-month cruise to Mars and six months of aerobraking to reach its science orbit, Mars Reconnaissance Orbiter began seeking out the history of water on Mars with its science instruments. The instruments zoom in for extreme close-up photography of the martian surface, analyze minerals, look for subsurface water, trace how much dust and water are distributed in the atmosphere, and monitor daily global weather.

The orbiter also carries an experimental navigation camera. For details on all mission stages, see the Mission Timeline. MRO Fact Sheets MRO Press Kits.
