NASA's Mars Reconnaissance Orbiter Examines Dramatic New Crater
2014-02-06 09:07:07

NASA Space rocks hitting Mars excavate fresh craters at a pace of more than 200 per year, but few new Mars scars pack as much visual punch as one seen in a NASA image released today. The image from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter shows a crater about 100 feet (30 meters) in diameter at the center of a radial burst painting the surface with a pattern of bright and dark tones. The scar appeared at some time between...

NASA Curiosity Team Looks For Safer Route To Mount Sharp
2014-01-30 06:39:31

[ Watch the Video: Curiosity Looking For A Safer Route ] Lawrence LeBlond for redOrbit.com - Your Universe Online A NASA team is currently considering an alternate route for Mars rover Curiosity’s trek toward Mount Sharp after considerable wheel damage has occurred over much of the last year. In a new image of the terrain that lies ahead for Curiosity, a small sand dune may make for a favorable route for the team. The thinking is that Curiosity may be able to avoid some rough...

Lee Rannals for redOrbit.com - Your Universe Online A new image taken by NASA's Mars Reconnaissance Orbiter (MRO) shows the space agency’s Curiosity rover on the surface of Mars viewed from orbit. The new image was taken on December 11, 2013 by MRO’s High Resolution Imaging Science Experiment (HiRISE) camera. Not only does the picture feature Curiosity driving inside Gale Crater, but it also shows tracks the rover’s tires have left behind as it makes its way across the Red Planet....

MRO Image Analysis Suggests Possible Salt Water On Mars
2013-12-10 19:42:05

Brett Smith for redOrbit.com – Your Universe Online For decades, scientists have been on a quest to find liquid water on the surface of Mars and new images from the Mars Reconnaissance Orbiter may finally provide that evidence. Newly released images from NASA clearly show dark streaks seasonally advancing down slopes close to the Martian equator, which space agency scientists say could be due to salty water. "The equatorial surface region of Mars has been regarded as dry, free of...

WASHINGTON, Dec. 10, 2013 /PRNewswire-USNewswire/ -- NASA's Mars Reconnaissance Orbiter (MRO) has revealed to scientists slender dark markings -- possibly due to salty water - that advance seasonally down slopes surprisingly close to the Martian equator. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) "The equatorial surface region of Mars has been regarded as dry, free of liquid or frozen water, but we may need to rethink that," said Alfred McEwen of the University...

Image Of The Mars Rover 10 Years After Launch

NASA's Jet Propulsion Laboratory An image from Mars orbit taken 10 years after the launch of NASA's Mars Exploration Rover Opportunity shows the long-lived rover on its trek to a new destination on Mars. The color image taken July 8, 2013, by the High Resolution Imaging Science Experiment (HiRISE) instrument on NASA's Mars Reconnaissance Orbiter catches Opportunity crossing relatively level ground called "Botany Bay" on its way to a rise called "Solander Point." The image is...

PASADENA, Calif., June 11, 2013 /PRNewswire-USNewswire/ -- NASA research indicates hunks of frozen carbon dioxide -- dry ice -- may glide down some Martian sand dunes on cushions of gas similar to miniature hovercraft, plowing furrows as they go. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) Researchers deduced this process could explain one enigmatic class of gullies seen on Martian sand dunes by examining images from NASA's Mars Reconnaissance Orbiter (MRO) and...

Mars Is Bombarded By 200 Asteroids A Year
2013-05-16 04:04:41

Lee Rannals for redOrbit.com - Your Universe Online Scientists believe Mars may be rocked by more than 200 small asteroids or bits of comets per year. Researchers using images from NASA's Mars Reconnaissance Orbiter identified 248 new impact sites on parts of the Martian surface in the past decade. Their 200-impacts-per-year estimation is a calculation based on the number found in a systematic survey of a portion of the planet. MRO's High Resolution Imaging Science Experiment...

Mars Orbiter Finds Evidence Of Soviet Union Lander
2013-04-12 05:38:54

April Flowers for redOrbit.com - Your Universe Online NASA's Mars Reconnaissance Orbiter may have captured images of hardware from a Soviet era spacecraft that landed on Mars in 1971. Russian citizen enthusiasts were following news about NASA's Curiosity rover and Mars when they found four features in a five-year old image from the Mars Reconnaissance Orbiter. The features resemble four pieces of hardware from the Soviet Mars 3 mission: the parachute, heat shield, terminal retrorocket...
