=== ''Mars Observer'' ===
{{main|Mars Observer}}
''Mars Observer'' was a robotic spacecraft designed to study the [[geoscience]] and climate of [[Mars]]. The first of the proposed Observer series of planetary missions, it was launched by [[NASA]] on September 25, 1992. Three days before ''Mars Observer'' was scheduled to enter the orbit of Mars, contact with the spacecraft was lost. Attempts to re-establish communication with the spacecraft were unsuccessful.

A few photographs were indeed taken, and these were the bulk of data collected.
