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 - National Aeronautics and Space AdministrationPasadena, CA – 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.

The longest-active rover on Mars also will, for the first time, visit the interior of the crater it has worked beside for the last five years. These activities are part of a two-year extended mission that began October 1st, the newest in a series of extensions going back to the end of Opportunity’s prime mission in April 2004.

Opportunity launched on July 7th, 2003 and landed on Mars on January 24th, 2004 (PST), on a planned mission of 90 Martian days, which is equivalent to 92.4 Earth days.

This scene from NASA's Mars rover Opportunity shows "Wharton Ridge," which forms part of the southern wall of "Marathon Valley" on the rim of Endeavour Crater. The ridge's name honors the memory of astrobiologist Robert A. Wharton (1951-2012). The scene is presented in approximately true color. (NASA/JPL-Caltech/Cornell/Arizona State Univ.)

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’s Mars Curiosity Rover now picking rock targets for Laser by itself

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Mars rover Curiosity is now selecting rock targets for its laser spectrometer — the first time autonomous target selection is available for an instrument of this kind on any robotic planetary mission.

Using software developed at NASA’s Jet Propulsion Laboratory, Pasadena, California, Curiosity is now frequently choosing multiple targets per week for a laser and a telescopic camera that are parts of the rover’s Chemistry and Camera (ChemCam) instrument. Most ChemCam targets are still selected by scientists discussing rocks or soil seen in images the rover has sent to Earth, but the autonomous targeting adds a new capability.

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’s Mars Curiosity Rover finds differences between Earth and Mars’ Sand Dunes

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Some of the wind-sculpted sand ripples on Mars are a type not seen on Earth, and their relationship to the thin Martian atmosphere today provides new clues about the atmosphere’s history.

The determination that these mid-size ripples are a distinct type resulted from observations by NASA’s Curiosity Mars rover. Six months ago, Curiosity made the first up-close study of active sand dunes anywhere other than Earth, at the “Bagnold Dunes” on the northwestern flank of Mars’ Mount Sharp.

Two sizes of ripples are evident in this December 13th, 2015, view of a top of a Martian sand dune, from NASA's Curiosity Mars rover. Sand dunes and the smaller type of ripples also exist on Earth.

NASA’s Mars Rover Opportunity finishes work at Marathon Valley on Mars

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – “Marathon Valley,” slicing through a large crater’s rim on Mars, has provided fruitful research targets for NASA’s Opportunity rover since July 2015, but the rover may soon move on.

Opportunity recently collected a sweeping panorama from near the western end of this east-west valley. The vista shows an area where the mission investigated evidence about how water altered the ancient rocks and, beyond that, the wide floor of Endeavour Crater and the crater’s eastern rim about 14 miles (22 kilometers) away.

"Marathon Valley" on Mars opens to a view across Endeavour Crater in this scene from the Pancam of NASA's Mars rover Opportunity. The scene merges many exposures taken during April and May 2016. The view spans from north (left) to west-southwest. Its foreground shows the valley's fractured texture. (NASA/JPL-Caltech/Cornell Univ./Arizona State Univ.)

NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – 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.

A new image shows the view overlooking the valley below and catches the rover’s own shadow and wheel tracks as Opportunity heads toward its next target.

A shadow and tracks of NASA's Mars rover Opportunity appear in this March 22, 2016, image, which has been rotated 13.5 degrees to adjust for the tilt of the rover. (NASA/JPL-Caltech)

NASA’s Mars Opportunity Rover travels up steep slope on Mars

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s senior Mars rover, Opportunity, is working adeptly in some of the most challenging terrain of the vehicle’s 12 years on Mars, on a slope of about 30 degrees.

Researchers are using Opportunity this month to examine rocks that may have been chemically altered by water billions of years ago. The mission’s current targets of investigation are from ruddy-tinted swaths the researchers call “red zones,” in contrast to tan bedrock around these zones.

The targets lie on “Knudsen Ridge,” atop the southern flank of “Marathon Valley,” which slices through the western rim of Endeavour Crater.

This scene from NASA's Mars Exploration Rover Opportunity looks upward at "Knudsen Ridge" from the valley below. (NASA/JPL-Caltech/Cornell Univ./Arizona State Univ.)
