Mars Reconnaissance Orbiter is a NASA spacecraft. It launched August 12, 2005 from Cape Canaveral, Florida, and arrived at Mars on March 10, 2006. It went into orbit around Mars, and has been studying the planet since then. The main area of study is looking for water on Mars, under the surface of Mars, and in the atmosphere of Mars. To do this, it has the largest telescope ever sent to another planet. The orbiter also works as a communications satellite. Its powerful antennas send and receive messages between NASA on Earth, and rovers on the surface of Mars.

Water ice excavated by an impact crater that formed between January and September 2008. The ice was identified spectroscopically using CRISM.
-
Lobate debris apron in Phlegra Montes, Cebrenia quadrangle. The debris apron is probably mostly ice with a thin covering of rock debris, so it could be a source of water for future Martian colonists. Scale bar is 500 m (1,600 ft).

Chloride deposits in Terra Sirenum
-
Two pictures from HiRISE showing how ice disappeared over time in a crater. The crater on the left is before ice disappeared. The crater is 6 meters in diameter and located in Cebrenia quadrangle.

Image of Phoenix landing on Mars, as seen by HiRISE. Although in the image it appears to be descending into the crater, Phoenix actually landed 20 km (12 mi) away from it.

Opportunity as seen by HiRISE on January 29, 2009. Opportunity is on its way to Endeavour Crater, 17 km (11 mi) away at this point.
