Mars Reconnaissance Orbiter
In this artist's conception of the Mars Reconnaissance Orbiter, note the thin, long pole in the center. That's the SHARAD antenna, which will be able to view liquid or water in up to 1 kilometer of the Mars crust. Also center, covered by blankets, is the High Resolution Imaging Science Experiment camera, which will provide the highest-resolution photos to date.
NASA tested the High Resolution Imaging Science Experiment camera while en route to Mars. The camera took this picture of Earth's moon from 6 million miles away. To the naked eye, the moon would appear as a star-like point of light at such a distance. The test verified the camera's focusing capability and provided an opportunity for calibration.
