Frozen beneath a region of cracked and pitted plains on Mars lies about as much water as what's in Lake Superior, largest of the Great Lakes, researchers using NASA's Mars Reconnaissance Orbiter have determined.
"ESA and its international team have added an important achievement to the exploration of Mars by putting the Trace Gas Orbiter into orbit around the Red Planet as a platform for science investigation and communication infrastructure," said Jim Green, director, Planetary Science Division, NASA Headquarters in Washington. "The Trace Gas Orbiter enables ESA now to provide NASA with a UHF data relay package valuable for the upcoming Mars InSight and Mars 2020 missions. ESA will also use it for the ExoMars rover to be launched in 2020."
Ten thousand volunteers viewing images of Martian south polar regions have helped identify targets for closer inspection, yielding new insights about seasonal slabs of frozen carbon dioxide and erosional features known as "spiders."
New global images of Mars from the MAVEN mission show the ultraviolet glow from the Martian atmosphere in unprecedented detail, revealing dynamic, previously invisible behavior. They include the first images of "nightglow" that can be used to show how winds circulate at high altitudes. Additionally, dayside ultraviolet imagery from the spacecraft shows how ozone amounts change over the seasons and how afternoon clouds form over giant Martian volcanoes.
NASA's Opportunity Mars rover will drive down a gully carved long ago by a fluid that might have been water, according to the latest plans for the 12-year-old mission. No Mars rover has done that before.
Today, NASA's Mars Atmosphere and Volatile EvolutioN (MAVEN) mission completed one Mars year of science observations. One Mars year is just under two Earth years. MAVEN launched on Nov. 18, 2013, and went into orbit around Mars on Sept. 21, 2014. During its time at Mars, MAVEN has answered many questions about the Red Planet.
After collecting drilled rock powder in arguably the most scenic landscape yet visited by a Mars rover, NASA's Curiosity mobile laboratory is driving toward uphill destinations as part of its two-year mission extension that commenced Oct. 1.
It'll be years before the first astronauts leave the launch pad on Earth to journey to Mars. But starting Sept. 19, visitors to the Kennedy Space Center Visitor Complex in Florida will get a taste of what those astronauts will see when they touch down on the Red Planet.
The layered geologic past of Mars is revealed in stunning detail in new color images returned by NASA's Curiosity Mars rover, which is currently exploring the "Murray Buttes" region of lower Mount Sharp. The new images arguably rival photos taken in U.S. National Parks.
New findings using data from NASA's Mars Reconnaissance Orbiter show that gullies on modern Mars are likely not being formed by flowing liquid water. This new evidence will allow researchers to further narrow theories about how Martian gullies form, and reveal more details about Mars' recent geologic processes.
NASA's Curiosity Mars rover autonomously selects some targets for the laser and telescopic camera of its ChemCam instrument. For example, on-board software analyzed the Navcam image at left, chose the target indicated with a yellow dot, and pointed ChemCam for laser shots and the image at right.
NASA has selected five U.S. aerospace companies to conduct concept studies for a potential future Mars orbiter mission. Such a mission would continue key capabilities including telecommunications and global high-resolution imaging in support of the agency's Journey to Mars.
After an extensive review process and passing a major development milestone, NASA is ready to proceed with final design and construction of its next Mars rover, currently targeted to launch in summer of 2020 and arrive on the Red Planet in February 2021.
NASA will host a Facebook Live event at 10 a.m. PDT (1 p.m. EDT) Friday, July 15, to talk about the science and technology aboard NASA's next Mars rover, Mars 2020, and the significant step the agency is taking on its Journey to Mars, proceeding with final design and construction of the robotic explorer.
Some dusty parts of Mars get as cold at night year-round as the planet's poles do in winter, even regions near the equator in summer, according to new NASA findings based on Mars Reconnaissance Orbiter observations.
NASA is celebrating the first successful landing on Mars by a U.S. spacecraft – Viking 1 -- with a history discussion from 2 to 3:30 p.m. EDT Tuesday, July 19, and a Viking 40th anniversary symposium 8 a.m. to 5:10 p.m. Wednesday, July 20 at NASA’s Langley Research Center in Hampton, Virginia.
NASA's Curiosity Mars rover is resuming full operations today, following work by engineers to investigate why the rover put itself into a safe standby mode on July 2. The rover team brought Curiosity out of safe mode on July 9.
Ever since it was announced that there may be evidence of liquid water on present-day Mars, NASA scientists have wondered how best to further investigate these long, seasonally changing dark streaks in the hope of finding evidence of life -- past or present -- on the Red Planet
After decades of research to discern seasonal patterns in Martian dust storms from images showing the dust, but the clearest pattern appears to be captured by measuring the temperature of the Red Planet's atmosphere.
NASA's long-lived Mars rover Opportunity is driving to an alternative hillside target after a climb on the steepest slope ever tackled by any Mars rover. Opportunity could not quite get within reach of a target researchers hoped the rover could touch earlier this month.
What might it look like if you were walking around on Mars? A group of researchers at NASA's Jet Propulsion Laboratory, Pasadena, California, has been working on methods to take this question from the realm of imagination to the mind-bending domain of mixed reality.
NASA's Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight) mission to study the deep interior of Mars is targeting a new launch window that begins May 5, 2018, with a Mars landing scheduled for Nov. 26, 2018.
Just weeks before the historic encounter of comet C/2013 A1 (Siding Spring) with Mars in October 2014, NASA's Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft entered orbit around the Red Planet.
