NASA - National Aeronautics and Space AdministrationPasadena, CA – A view from NASA’s Mars Reconnaissance Orbiter on April 8th, 2015, catches sight of NASA’s Curiosity Mars rover passing through a valley called “Artist’s Drive” on the lower slope of Mount Sharp.

The image from the orbiter’s High Resolution Imaging Science Experiment (HiRISE) camera shows the rover’s position after a drive of about 75 feet (23 meters) during the 949th Martian day, or sol, of the rover’s work on Mars.

NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Curiosity Mars rover is continuing science observations while on the move this month. On April 16th, the mission passed 10 kilometers (6.214 miles) of total driving since its 2012 landing, including about a fifth of a mile (310 meters) so far this month.

The rover is trekking through a series of shallow valleys between the “Pahrump Hills” outcrop, which it investigated for six months, and the next science destination, “Logan Pass,” which is still about 200 yards, or meters, ahead toward the southwest.

NASA’s Mars Curiosity rover measurements of Weather, Soil reveals possibility of Liquid Brine on Mars

NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Martian weather and soil conditions that NASA’s Curiosity rover has measured, together with a type of salt found in Martian soil, could put liquid brine in the soil at night.

Perchlorate identified in Martian soil by the Curiosity mission, and previously by NASA’s Phoenix Mars Lander mission, has properties of absorbing water vapor from the atmosphere and lowering the freezing temperature of water. This has been proposed for years as a mechanism for possible existence of transient liquid brines at higher latitudes on modern Mars, despite the Red Planet’s cold and dry conditions.

NASA’s Mars Reconnaissance Orbiter returns to full operation after computer swap

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Mars Reconnaissance Orbiter, at Mars since 2006, made an unplanned switch on Wednesday from one main computer to a redundant one onboard, triggering a hiatus in planned activities.

Sensing the computer swap, the orbiter put itself into a precautionary safe standby mode. It remained healthy, in communication and fully powered. The mission’s operations team expects the Mars Reconnaissance Orbiter to resume full duty within a few days, including communication relays and science observations.

NASA’s MAVEN spacecraft discovers Dust Cloud and Aurora in Mars’ Atmosphere

 

Written by Dwayne Brown
NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft has observed two unexpected phenomena in the Martian atmosphere: an unexplained high-altitude dust cloud and aurora that reaches deep into the Martian atmosphere.

The presence of the dust at orbital altitudes from about 93 miles (150 kilometers) to 190 miles (300 kilometers) above the surface was not predicted. Although the source and composition of the dust are unknown, there is no hazard to MAVEN and other spacecraft orbiting Mars.

NASA’s InSight mission to Mars examines site for landing

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s next mission to Mars, scheduled to launch one year from today to examine the Red Planet’s deep interior and investigate how rocky planets like Earth evolved, now has one specific site under evaluation as the best place to land and deploy its science instruments.

The mission called InSight — an acronym for “Interior Exploration using Seismic Investigations, Geodesy and Heat Transport” — is scheduled to launch from Vandenberg Air Force Base, California. The launch period runs from March 4th to March 30th, 2016, and will mark the first California launch of an interplanetary mission.

This map shows the single area under continuing evaluation as the InSight mission's Mars landing site, as of a year before the mission's May 2016 launch. (NASA/JPL-Caltech)

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

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

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

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

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

 

Written by Guy Webster

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 Exploration Rover Opportunity is continuing its traverse southward on the western rim of Endeavour Crater during the fall of 2014, stopping to investigate targets of scientific interest along way. (NASA/JPL-Caltech)
