NASA’s Mars Curiosity Rover captures image of Sunset on Mars

NASA - National Aeronautics and Space AdministrationPasadena, CA – The sun dips to a Martian horizon in a blue-tinged sky in images sent home to Earth this week from NASA’s Curiosity Mars rover.

Curiosity used its Mast Camera (Mastcam) to record the sunset during an evening of skywatching on April 15th, 2015.

The imaging was done between dust storms, but some dust remained suspended high in the atmosphere. The sunset observations help researchers assess the vertical distribution of dust in the atmosphere.

NASA’s Mars Curiosity Rover takes timeout to investigate Valley on Mars

NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Researchers slightly detoured NASA’s Curiosity Mars rover from the mission’s planned path in recent days for a closer look at a hillside site where an ancient valley had been carved out and refilled.

The rover made observations and measurements there to address questions about how the channel formed and filled. Then it resumed driving up Mount Sharp, where the mission is studying the rock layers. The layers reveal chapters in how environmental conditions and the potential to support microbial life changed in Mars’ early history.

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 Curiosity Mars rover heads towards next observation point on Mars, Logan Pass

 

Written by Guy Webster
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 Curiosity Mars rover used its Navigation Camera (Navcam) to capture this scene toward the west just after completing a drive that took the mission's total driving distance on Mars past 10 kilometers (6.214 miles). (NASA/JPL-Caltech)

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

 

Written by Guy Webster

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 missions have discovered an abundance of Water in our Solar System

 

Written by Preston Dyches
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – As NASA missions explore our solar system and search for new worlds, they are finding water in surprising places. Water is but one piece of our search for habitable planets and life beyond Earth, yet it links many seemingly unrelated worlds in surprising ways.

“NASA science activities have provided a wave of amazing findings related to water in recent years that inspire us to continue investigating our origins and the fascinating possibilities for other worlds, and life, in the universe,” said Ellen Stofan, chief scientist for the agency. “In our lifetime, we may very well finally answer whether we are alone in the solar system and beyond.”

NASA’s Mars Curiosity Rover examines Martian Atmosphere to learn about it’s past

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Curiosity rover is using a new experiment to better understand the history of the Martian atmosphere by analyzing xenon.

While NASA’s Curiosity rover concluded its detailed examination of the rock layers of the “Pahrump Hills” in Gale Crater on Mars this winter, some members of the rover team were busy analyzing the Martian atmosphere for xenon, a heavy noble gas.

Curiosity’s Sample Analysis at Mars (SAM) experiment analyzed xenon in the planet’s atmosphere. Since noble gases are chemically inert and do not react with other substances in the air or on the ground, they are excellent tracers of the history of the atmosphere.

NASA’s Mars Curiosity rover discovers Two Tone Mineral Veins on side of Martian Mountain

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Two-tone mineral veins at a site NASA’s Curiosity rover has reached by climbing a layered Martian mountain offer clues about multiple episodes of fluid movement. These episodes occurred later than the wet environmental conditions that formed lake-bed deposits the rover examined at the mountain’s base.

Curiosity has analyzed rock samples drilled from three targets lower on the mountain in the past seven months. It found a different mineral composition at each, including a silica mineral named cristobalite in the most recent sample.

This March 18, 2015, view from the Mast Camera on NASA's Curiosity Mars rover shows a network of two-tone mineral veins at an area called "Garden City" on lower Mount Sharp. (NASA/JPL-Caltech/MSSS)

NASA’s Mars Curiosity Rover discovers Nitrogen on Mars

 

Written by Nancy Neal-Jones / William Steigerwald
NASA Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – A team using the Sample Analysis at Mars (SAM) instrument suite aboard NASA’s Curiosity rover has made the first detection of nitrogen on the surface of Mars from release during heating of Martian sediments.

The nitrogen was detected in the form of nitric oxide, and could be released from the breakdown of nitrates during heating. Nitrates are a class of molecules that contain nitrogen in a form that can be used by living organisms. The discovery adds to the evidence that ancient Mars was habitable for life.

This self-portrait of NASA's Mars rover Curiosity combines dozens of exposures taken by the rover's Mars Hand Lens Imager (MAHLI) during the 177th Martian day, or sol, of Curiosity's work on Mars (Feb. 3, 2013), plus three exposures taken during Sol 270 (May 10, 2013) to update the appearance of part of the ground beside the rover.

NASA successfully tests new Mars Landing Technology

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – It’s tricky to get a spacecraft to land exactly where you want. That’s why the area where the Mars rover Curiosity team had targeted to land was an ellipse that may seem large, measuring 12 miles by 4 miles (20 by 7 kilometers).

Engineers at NASA’s Jet Propulsion Laboratory in Pasadena, California, have been developing cutting-edge technologies that would enable spacecraft to land at a specific location on Mars — or any other planetary body — with more precision than ever before.
