NASA HiRise Image: MARS Rover Curiosity on Surface of Mars

Another stunning photograph from space shows NASA’s Curiosity rover sitting safely on the surface of Mars.

Taken with the Mars Reconnaissance Orbiter’s HiRISE camera, the picture captures incredible details of the surface along with the robotic components that helped Curiosity stick its landing.

“This is like the crime scene photo here,” said Sarah Milkovich (@milkysa), HiRISE investigation scientist during a NASA press conference Aug. 7.

Zooming in close, black streaks can be seen where the rover’s rockets disturbed bright surface dust, revealing darker soil underneath.

Researchers have used these streak patterns to infer Curiosity’s orientation, which matches up nicely with information from the rover’s first pictures on the surface.

Down and to the right is the rover’s heat shield, which protected the probe as it plummeted through the Martian atmosphere. It is sitting about 4000 feet from Curiosity on the surface.

The backshell and parachute — over to the lower left in the image — sit about 2000 feet from the rover while the sky crane, which gently lowered the rover to the ground, is above and to the left about 2100 feet from Curiosity.

NASA engineers will continue poring over the photo for clues of exactly how Curiosity’s complex landing sequence unfolded.

NASA Recon Imager: Jupiter's Moon IO - Montage

This montage of New Horizons images shows Jupiter and its volcanic moon Io, and were taken during the spacecraft's Jupiter flyby in early 2007.

The image of Jupiter is an infrared color composite taken by the spacecraft's near-infrared imaging spectrometer, the Linear Etalon Imaging Spectral Array.

The infrared wavelengths used highlight variations in the altitude of the Jovian cloud tops, with blue denoting high-altitude clouds and hazes, and red indicating deeper clouds.

The prominent bluish-white oval is more commonly known as the Great Red Spot.

The observation was made at a solar phase angle of 75 degrees but has been projected onto a crescent to remove distortion caused by Jupiter's rotation during the scan.

The image of Io is an approximately true-color composite taken by the panchromatic Long-Range Reconnaissance Imager with color information provided by the Multispectral Visible Imaging Camera.

The image shows a major eruption in progress on Io's night side, at the northern volcano Tvashtar. Incandescent lava glows red beneath a volcanic plume, whose uppermost portions are illuminated by sunlight. The plume appears blue due to scattering of light by small particles within it.

This montage originally appeared on the cover of the Oct. 12, 2007, issue of Science magazine.

Mars Reconaissance Orbiter: Radar Map Of Buried Martian Ice

A radar on NASA's Mars Reconnaissance Orbiter has detected widespread deposits of glacial ice in the mid-latitudes of Mars.

Extensive radar mapping of the middle-latitude region of northern Mars shows that thick masses of buried ice are quite common beneath protective coverings of rubble.

The ability of NASA's Mars Reconnaissance Orbiter to continue charting the locations of these hidden glaciers and ice-filled valleys - first confirmed by radar two years ago - adds clues about how these deposits may have been left as remnants when regional ice sheets retreated.

The subsurface ice deposits extend for hundreds of kilometers, or miles, in the rugged region called Deuteronilus Mensae, about halfway from the equator to the Martian north pole.

Jeffrey Plaut of NASA's Jet Propulsion Laboratory, Pasadena, Calif., and colleagues prepared a map of the region's confirmed ice for presentation at this week's 41st Lunar and Planetary Science Conference near Houston.

The Shallow Radar instrument on the orbiter has obtained more than 250 observations of the study area, which is about the size of California.

"We have mapped the whole area with a high density of coverage," Plaut said. "These are not isolated features. In this area, the radar is detecting thick subsurface ice in many locations." The common locations are around the bases of mesas and scarps, and confined within valleys or craters.
