NASA’s Mars Rover Opportunity’s distance traveled on Mars nears that of a Marathon Race

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Mars Exploration Rover Opportunity is nearing a location on Mars at which its driving distance will surpass the length of a marathon race.

A drive on February 8th, 2015, put the rover within 220 yards (200 meters) of this marathon accomplishment. An Olympic marathon is 26.219 miles (42.195 kilometers).

Opportunity is headed for a portion of the western rim of Endeavour Crater where observations by NASA’s Mars Reconnaissance Orbiter have detected multiple types of clay minerals. These minerals are indicative of an ancient wet environment where water was more neutral rather than harshly acidic.

In February 2015, NASA's Mars Exploration Rover Opportunity is approaching a cumulative driving distance on Mars equal to the length of a marathon race. This map shows the rover's position relative to where it could surpass that distance. (NASA/JPL-Caltech/Univ. of Arizona)

NASA’s Mars Reconnaissance Orbiter has made 40,000 trips around Mars since 2006

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Mars Reconnaissance Orbiter passed a mission milestone of 40,000 orbits on February 7th, 2015, in its ninth year of returning information about the atmosphere, surface and subsurface of Mars, from equatorial to polar latitudes.

The mission’s potent science instruments and extended lifespan have revealed that Mars is a world more dynamic and diverse than was previously realized. Now in its fourth mission extension after a two-year prime mission, the orbiter is investigating seasonal and longer-term changes, including some warm-season flows that are the strongest evidence so far for liquid water on Mars today.

This view of Martian surface features shaped by effects of winds was captured by the HiRISE camera on NASA's Mars Reconnaissance Orbiter on Jan. 4, 2015. The spacecraft has been orbiting Mars since March 2006. On Feb. 7, 2015, it completed its 40,000th orbit around Mars. (NASA/JPL-Caltech/Univ. of Arizona)

NASA’s Mars Reconnaissance Orbiter spots Beagle 2 Mars Lander that’s been lost on Mars since 2003

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – The Beagle 2 Mars Lander, built by the United Kingdom, has been thought lost on Mars since 2003, but has now been found in images from NASA’s Mars Reconnaissance Orbiter.

A set of three observations with the orbiter’s High Resolution Imaging Science Experiment (HiRISE) camera shows Beagle 2 partially deployed on the surface of the planet, ending the mystery of what happened to the mission more than a decade ago. They show that the lander survived its December 25th, 2003, touchdown enough to at least partially deploy its solar arrays.

This annotated image shows where features seen in an observation by NASA's Mars Reconnaissance Orbiter have been interpreted as hardware from the Dec. 25, 2003, arrival at Mars of the United Kingdom's Beagle 2 Lander. The image was taken in 2014 by the orbiter's HiRISE camera.

NASA’s Mars Rover Opportunity’s Flash Data Storage malfunctions

NASA - National Aeronautics and Space Administration

Pasadena, CA – Persistent computer resets and “amnesia” events on NASA’s Mars Exploration rover Opportunity that have occurred after reformatting the robot’s flash memory have prompted a shift to a working mode that avoids use of the flash data-storage system.

The most recent reformatting of Opportunity’s flash memory was last week. Following that, performance of the flash memory remained intermittent, and difficulty in placing data into the memory led to computer resets during the weekend.

NASA’s Mars Reconnaissance Orbiter images reveals new map showing ancient lakes and quakes on Mars

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Long ago, in the largest canyon system in our solar system, vibrations from “marsquakes” shook soft sediments that had accumulated in Martian lakes.

The shaken sediments formed features that now appear as a series of low hills apparent in a geological map based on NASA images. The map was released today by the U.S. Geological Survey (USGS).

Details of hilly terrain within a large Martian canyon are shown on a geological map based on observations from NASA's Mars Reconnaissance Orbiter and produced by the U.S. Geological Survey. Notations are explained in the legend with the full map, at http://pubs.usgs.gov/sim/3309/. (NASA/JPL-Caltech/Univ. of Arizona/USGS)

NASA Spacecraft analyzes effects of Comet Flyby on Mar’s Atmosphere

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Two NASA and one European spacecraft that obtained the first up-close observations of a comet flyby of Mars on October 19th, have gathered new information about the basic properties of the comet’s nucleus and directly detected the effects on the Martian atmosphere.

Data from observations carried out by NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) mission, NASA’s Mars Reconnaissance Orbiter (MRO), and a radar instrument on the European Space Agency’s (ESA’s) Mars Express spacecraft have revealed that debris from the comet added a temporary and very strong layer of ions to the ionosphere, the electrically charged layer high above Mars.

NASA’s Mars Curiosity Rover confirms first Mineral Mapped from Space

 

Written by Preston Dyches and Guy Webster

NASA - National Aeronautics and Space AdministrationPasadena, CA – Reddish rock powder from the first hole drilled into a Martian mountain by NASA’s Curiosity rover has yielded the mission’s first confirmation of a mineral mapped from orbit.

“This connects us with the mineral identifications from orbit, which can now help guide our investigations as we climb the slope and test hypotheses derived from the orbital mapping,” said Curiosity Project Scientist John Grotzinger, of the California Institute of Technology in Pasadena.

This image shows the first holes drilled by NASA's Mars rover Curiosity at Mount Sharp. The loose material near the drill holes is drill tailings and an accumulation of dust that slid down the rock during drilling. (NASA/JPL-Caltech/MSSS)

NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – The High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter captured views of comet C/2013 A1 Siding Spring while that visitor sped past Mars on Sunday (October 19th), yielding information about its nucleus.

The images are the highest-resolution views ever acquired of a comet coming from the Oort Cloud at the fringes of the solar system.

These images were taken of comet C/2013 A1 Siding Spring by NASA's Mars Reconnaissance Orbiter on Oct. 19, 2014, during the comet's close flyby of Mars and the spacecraft. (NASA/JPL-Caltech/University of Arizona)

NASA - National Aeronautics and Space AdministrationPasadena, CA – The longest-lived robot ever sent to Mars came through its latest challenge in good health, reporting home on schedule after sheltering behind Mars from possible comet dust.

NASA’s Mars Odyssey was out of communications with Earth, as planned, while conducting observations of comet C/2013 A1 Siding Spring on Sunday, October 19th, as the comet flew near Mars.

Science at NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA’s extensive fleet of science assets, particularly those orbiting and roving Mars, have front row seats to image and study a once-in-a-lifetime comet flyby on Sunday, October 19th.

Comet C/2013 A1, also known as comet Siding Spring, will pass within about 87,000 miles (139,500 kilometers) of the Red Planet — less than half the distance between Earth and our moon and less than one-tenth the distance of any known comet flyby of Earth.
