NASA - National Aeronautics and Space AdministrationPasadena, CA – Laser-zapping of a globular, golf-ball-size object on Mars by NASA’s Curiosity rover confirms that it is an iron-nickel meteorite fallen from the Red Planet’s sky.

Iron-nickel meteorites are a common class of space rocks found on Earth, and previous examples have been seen on Mars, but this one, called “Egg Rock,” is the first on Mars examined with a laser-firing spectrometer. To do so, the rover team used Curiosity’s Chemistry and Camera (ChemCam) instrument.

The dark, smooth-surfaced rock at the center of this Oct. 30, 2016, image from the Mast Camera (Mastcam) on NASA's Curiosity Mars rover was examined with laser pulses and confirmed to be an iron-nickel meteorite. It is about the size of a golf ball. (Credit: NASA/JPL-Caltech/MSSS)

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)

NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – The next target for NASA’s New Horizons mission — which made a historic flight past Pluto in July 2015 — apparently bears a colorful resemblance to its famous, main destination.

NASA’s Hubble Space Telescope data suggests that 2014 MU69, a small Kuiper Belt object (KBO) about a billion miles (1.6 billion kilometers) beyond Pluto, is as red, if not redder, than Pluto. This is the first hint at the surface properties of the far-flung object that New Horizons will survey on January 1st, 2019.

Pluto's present, hazy atmosphere is almost entirely free of clouds. However, scientists from NASA's New Horizons mission have identified some cloud candidates -- suggestive of possible, rare condensation clouds -- in images taken during the spacecraft's July 2015 flight through the Pluto system.

NASA’s Opportunity Rover to examine Gully on Mars that may have been created by Water

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

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 starts Two Year Mission Extension

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

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’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 gives green light to Mars Insight Mission Launch

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA is moving forward with a spring 2018 launch of its InSight mission to study the deep interior of Mars, following final approval this week by the agency’s Science Mission Directorate.

The Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight) mission was originally scheduled to launch in March of this year, but NASA suspended launch preparations in December due to a vacuum leak in its prime science instrument, the Seismic Experiment for Interior Structure (SEIS).

NASA has set a new launch opportunity, beginning May 5, 2018, for the InSight mission to Mars. InSight is the first mission dedicated to investigating the deep interior of Mars. (NASA/JPL-Caltech)

NASA’s Mars Odyssey orbiter data reveals no water in Seasonal Streaks on Mars

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Seasonal dark streaks on Mars that have become one of the hottest topics in interplanetary research don’t hold much water, according to the latest findings from a NASA spacecraft orbiting Mars.

The new results from NASA’s Mars Odyssey mission rely on ground temperature, measured by infrared imaging using the spacecraft’s Thermal Emission Imaging System (THEMIS). They do not contradict last year’s identification of hydrated salt at these flows, which since their 2011 discovery have been regarded as possible markers for the presence of liquid water on modern Mars.

Blue dots on this map indicate sites of recurring slope lineae (RSL) in part of the Valles Marineris canyon network on Mars. RSL are seasonal dark streaks that may be indicators of liquid water. The area mapped here has the highest density of known RSL on Mars. (NASA/JPL-Caltech/Univ. of Arizona)

NASA’s Mars Curiosity Rover captures 360 view of Murray Buttes on Mars

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Eroded mesas and buttes reminiscent of the U.S. Southwest shape part of the horizon in the latest 360-degree color panorama from NASA’s Curiosity Mars rover.

The rover used its Mast Camera (Mastcam) to capture dozens of component images of this scene on August 5th, 2016, four years after Curiosity’s landing inside Gale Crater.

The visual drama of Murray Buttes along Curiosity’s planned route up lower Mount Sharp was anticipated when the site was informally named nearly three years ago to honor Caltech planetary scientist Bruce Murray (1931-2013), a former director of NASA’s Jet Propulsion Laboratory, Pasadena, California. JPL manages the Curiosity mission for NASA.

This 360-degree vista was acquired on Aug. 5, 2016, by the Mastcam on NASA's Curiosity Mars rover as the rover neared features called "Murray Buttes" on lower Mount Sharp. The dark, flat-topped mesa seen to the left of the rover's arm is about 50 feet high and, near the top, about 200 feet wide. (NASA/JPL-Caltech/MSSS)
