The Mars Reconnaissance Orbiter (MRO) is a spacecraft designed to search for the existence of water on Mars and provide support for missions to Mars, as part of NASA's Mars Exploration Program.

The first successful spacecraft in the NASA Mariner program, it was a simplified version of the Block I spacecraft of the Ranger program and an exact copy of Mariner 1.

Mars Global Surveyor (MGS) was an American robotic space probe developed by NASA's Jet Propulsion Laboratory.

Deep Space 1 (DS1) was a NASA technology demonstration spacecraft which flew by an asteroid and a comet.

Ranger 6 was a lunar probe in the NASA Ranger program, a series of robotic spacecraft of the early and mid-1960s to obtain close-up images of the Moon's surface.

Launched on December 4, 1996, by NASA aboard a Delta II booster a month after the Mars Global Surveyor, it landed on July 4, 1997, on Mars's Ares Vallis.

It was manufactured by Lockheed Martin Space, was managed by NASA's Jet Propulsion Laboratory (JPL), and two of its three scientific instruments were built by European agencies.

The project was developed by NASA, and contracted out to Lockheed Martin, with an expected cost for the entire mission of US$297 million.
