NASA is developing the capabilities needed to send humans to an asteroid by 2025 and Mars in the 2030s - goals outlined in the bipartisan NASA Authorization Act of 2010 and in the U.S. National Space Policy, also issued in 2010.

The Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) aboard NASA's Mars Reconnaissance Orbiter obtained this spectrum for comet C/2013 A1 Siding Spring during the comet's close approach to Mars.

Five images of comet Siding Spring taken within a 35-minute period as it passed near Mars on Oct. 19, 2014, provide information about the size of the comet's nucleus. The images were acquired by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter.

This graph shows changes in apparent brightness of comet C/2013 A1 Siding Spring as it approached and receded from Mars, as seen by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter. The pattern suggests the comet rotates once every eight hours.

These two infrared images of comet C/2013 A1 Siding Spring were taken by the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) aboard NASA's Mars Reconnaissance Orbiter on Oct. 19, 2014. This Oort Cloud comet was making its first voyage through the inner solar system.

This artist's concept shows NASA's Mars orbiters lining up behind the Red Planet for their "duck and cover" maneuver to shield them fro comet dust that may result from the close flyby of comet Siding Spring (C/2013 A1) on Oct. 19, 2014.

This image shows the planned route (in yellow) of NASA's Curiosity rover from "Pahrump Hills" at the base of Mount Sharp, through the "Murray Formation," and south to the hematite ridge further up the flank of Mount Sharp. The rover's location is near Pahrump Hills noted with a green star on the top right of the image.

This color image shows the transition between the "Murray Formation," and the hematite ridge, which is made up of continuous layers that can be traced laterally for hundreds of meters. Between both areas is a dark band of material, which are the dunes that divide Murray Ridge and Hematite Ridge.
Geological Transition
Full Resolution
This image shows distinct bands of alternating tone and brightness within the "Murray Formation" on Mars. A black arrow points to those bands, which cut across diagonally in this image.

A path resembling a dotted line from the upper left to middle right of this image is the track left by an irregularly shaped, oblong boulder as it tumbled down a slope on Mars before coming to rest in an upright attitude at the downhill end of the track.

This pair of images covers one of many sites on Mars where researchers use the HiRISE camera on NASA's Mars Reconnaissance Orbiter to study changes in gullies on slopes. Changes such as the ones visible in deposits near the lower end of this gully occur during winter and early spring on Mars.

This April 6, 2014, image from the Context Camera on NASA's Mars Reconnaissance Orbiter was taken as a follow-up to discovery of a possible 2012 impact scar in images from the orbiter's Mars Color Imager. It reveals two craters within the darkened area (at center of the inscribed rectangle).

This March 20, 2014, image from the MARCI camera on NASA's Mars Reconnaissance Orbiter has a dark spot (at center of inscribed rectangle) noticed while the image was being examined for a weather report. Other observations confirmed that the spot is a scar from a space rock hitting Mars in 2012.

These images from the Context Camera on NASA's Mars Reconnaissance Orbiter were taken before and after an apparent impact scar appeared in the area in March 2012. Comparing the Jan. 16, 2012, image (left) with the April 6, 2014, one (right) confirms that fresh craters appeared during the interval.
