Boeing has put forward its own idea to help NASA get its Mars Sample Return project back on track and on budget. NASA issued a solicitation for new ideas to get scientifically invaluable Martian material to Earth after being told the current plan is too expensive (about $11 billion), while also being too complex and facing scheduling issues.  Former NASA Chief Scientist Jim Green presented Boeing’s vision for a rejiggered Mars sample return mission concept at the annual Humans to Mars Summit last week.  Related: NASA’s Mars Sample Return in jeopardy…

For the past month, NASA’s Curiosity rover has been shadowing Gediz Vallis, a channel that scientists think may be the fossil of an ancient Martian river.  Last week, Curiosity reached the north side of Pinnacle Ridge, part of a rock wall that looms over Gediz Vallis. In fact, after Curiosity navigated bumpy ground to do that, it found that the ridge’s south side is navigable. That left Curiosity’s overseers at NASA’s Jet Propulsion Laboratory (JPL) in Southern California with a choice: Should they keep on their planned course, continuing to…

Two NASA spacecraft will pay special attention to increasing levels of radiation that bombard Mars during this year’s approaching solar maximum, to better prepare astronauts for future missions to the Red Planet.  Every 11 years or so, the sun experiences a peak in activity known as solar maximum, due to its strong and constantly shifting magnetic fields. During this period of the solar cycle, the frequency and intensity of sunspots on the solar surface increases, generating solar flares and coronal mass ejections that send powerful streams of solar radiation out…

NASA has selected four volunteers to go on a mission to Mars — without actually leaving Earth. The simulated mission to the Red Planet will take place at a habitat created at NASA’s Johnson Space Center in Houston; it will simulate what it would be like for astronauts to live and work on Mars for 45 days. The team includes Jason Lee, Stephanie Navarro, Shareef Al Romaithi and Piyumi Wijesekara. The four will call the agency’s Human Exploration Research Analog (HERA) home from May 10 through June 24. Two alternate…

Since 2012, NASA’s Curiosity rover has repeatedly detected methane on Mars, specifically near its landing site inside the 96-mile-wide (154 kilometers) Gale Crater.  But that Mars methane is behaving erratically. It only appears at night, it fluctuates seasonally and it spikes unexpectedly to levels 40 times higher than usual. To make things more puzzling, the gas isn’t present in appreciable amounts high in the Martian atmosphere, and it hasn’t been detected near the surface in other Red Planet locales. So what’s going on at Gale Crater? A group of NASA…

NASA’s history-making Ingenuity helicopter covered a lot of ground on Mars over the past three years, as a new video shows. The video, which was released on Thursday (April 18) by NASA’s Jet Propulsion Laboratory (JPL), shows where Ingenuity went on each of its 72 Red Planet sorties, linking each flight line together in an otherworldly Etch a Sketch creation. This work of art throws Ingenuity’s epic achievements into stark relief, showing the tough terrain the 4-pound (1.8 kilograms) chopper negotiated and the impressive distance it traveled — 10.5 miles…
