NASA - National Aeronautics and Space AdministrationPasadena, CA – Data from each of the two rovers active on Mars reached Earth last week in the successful first relay test of a NASA radio aboard Europe’s new Trace Gas Orbiter (TGO).

The transmissions from NASA rovers Opportunity and Curiosity, received by one of the twin Electra radios on the orbiter on November 22nd, mark a strengthening of the international telecommunications network supporting Mars exploration. The orbiter’s main radio for communications with Earth subsequently relayed onward to Earth the data received by Electra.

A NASA radio on Europe's Trace Gas Orbiter, which reached Mars in October 2016, has succeeded in its first test of receiving data from NASA Mars rovers, both Opportunity and Curiosity. This graphic depicts the geometry of the relay from Opportunity to the orbiter, which then sent the data to Earth.

NASA’s Mars Reconnaissance Orbiter data reveals Ice Deposit on Mars has more water than Lake Superior

 

Written by Dwayne Brown / Laurie Cantillo
NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – 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.

Scientists examined part of Mars’ Utopia Planitia region, in the mid-northern latitudes, with the orbiter’s ground-penetrating Shallow Radar (SHARAD) instrument.

Analyses of data from more than 600 overhead passes with the onboard radar instrument reveal a deposit more extensive in area than the state of New Mexico.

NASA’s Mars Reconnaissance Orbiter finds area where Schiaparelli Lander crashed on Mars

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – The most powerful telescope orbiting Mars is providing new details of the scene near the Martian equator where Europe’s Schiaparelli test lander hit the surface last week.

An October 25th observation using the High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter shows three impact locations within about 0.9 mile (1.5 kilometers) of each other.

The scene shown by HiRISE includes three locations where hardware reached the ground. A dark, roughly circular feature is interpreted as where the lander itself struck.

This Oct. 25, 2016, image from the HiRISE camera on NASA's Mars Reconnaissance Orbiter shows the area where the Europe's Schiaparelli test lander struck Mars, with magnified insets of three sites where spacecraft components hit the ground. It adds detail not seen in earlier imaging of the site. (NASA/JPL-Caltech/Univ. of Arizona)

Volunteers examine NASA’s Mars Reconnaissance Orbiter images to find areas worth further study

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – 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.”

From the comfort of home, the volunteers have been exploring the surface of Mars by reviewing images from the Context Camera (CTX) on NASA’s Mars Reconnaissance Orbiter and identifying certain types of seasonal terrains near Mars’ south pole.

This image shows spidery channels eroded into Martian ground. It is a Sept. 12, 2016, example from HiRISE camera high-resolution observations of more than 20 places that were chosen in 2016 on the basis of about 10,000 volunteers' examination of Context Camera lower-resolution views of larger areas.

NASA Study finds patterns in the occurrence of Global Dust Storms on Mars

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Global dust storms on Mars could soon become more predictable — which would be a boon for future astronauts there — if the next one follows a pattern suggested by those in the past.

A published prediction, based on this pattern, points to Mars experiencing a global dust storm in the next few months. “Mars will reach the midpoint of its current dust storm season on October 29th of this year. Based on the historical pattern we found, we believe it is very likely that a global dust storm will begin within a few weeks or months of this date,” James Shirley, a planetary scientist at NASA’s Jet Propulsion Laboratory, Pasadena, California.

Two 2001 images from the Mars Orbiter Camera on NASA's Mars Global Surveyor orbiter show a dramatic change in the planet's appearance when haze raised by dust-storm activity in the south became globally distributed. The images were taken about a month apart. (NASA/JPL-Caltech/MSSS)

NASA - National Aeronautics and Space AdministrationPasadena, CA – 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 October 1st.

The destinations include a ridge capped with material rich in the iron-oxide mineral hematite, about a mile-and-a-half (two-and-a-half kilometers) ahead, and an exposure of clay-rich bedrock beyond that.

This September 2016 self-portrait of NASA's Curiosity Mars rover shows the vehicle at the "Quela" drilling location in the scenic "Murray Buttes" area on lower Mount Sharp. The panorama was stitched together from multiple images taken by the MAHLI camera at the end of the rover's arm. (NASA/JPL-Caltech/MSSS)

NASA developing systems to utilize resources available in the Solar System

 

Written by Bob Granath
NASA’s Kennedy Space Center

NASA - National Aeronautics and Space AdministrationFlorida – As NASA continues preparing for the Journey to Mars, the technology now in development is expanding beyond the spacecraft and propulsion systems needed to get there. NASA scientists and engineers also are developing systems to harness abundant resources available in the solar system to support these pioneering missions.

The practice is called in-situ resource utilization, or ISRU. Like early European settlers coming to America, planetary pioneers will not be able to take everything they need, so many supplies will need to be gathered and made on site.

NASA’s Resource Prospector mission, currently being developed, is designed to be the first mining expedition on the moon. Using resources found in extraterrestrial soil, or in-situ resource utilization, will foster more affordable and sustainable human exploration to many deep-space destinations. (NASA)

NASA’s Mars Reconnaissance Orbiter data reveals some Mars Lakes older than others

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Lakes and snowmelt-fed streams on Mars formed much later than previously thought possible, according to new findings using data primarily from NASA’s Mars Reconnaissance Orbiter.

The recently discovered lakes and streams appeared roughly a billion years after a well-documented, earlier era of wet conditions on ancient Mars. These results provide insight into the climate history of the Red Planet and suggest the surface conditions at this later time may also have been suitable for microbial life.

Valleys much younger than well-known ancient valley networks on Mars are evident near the informally named "Heart Lake" on Mars. (NASA/JPL-Caltech/ASU)

NASA’s Mars Reconnaissance Orbiter data shows Gullies on Mars probably not created by Water

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – 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.

Scientists use the term “gully” for features on Mars that share three characteristics in their shape: an alcove at the top, a channel, and an apron of deposited material at the bottom.

Martian gullies as seen in the top image from HiRISE on NASA's Mars Reconnaissance Orbiter resemble gullies on Earth that are carved by liquid water. (NASA/JPL-Caltech/UA/JHUAPL)
