Viking 2

Viking 2 repeated the orbiter–lander architecture at Utopia Planitia, adding a second location for Mars surface measurements and life-detection experiments.

viking-2 is a mars lander and orbiter focused on Mars; its mission record separates planned measurements from the results actually documented.

For viking-2, the defining design choice was to use a mars lander and orbiter for second viking mars landing. That choice determines what the spacecraft can observe, how it moves or operates, and what risks the team must manage.

For viking-2, the cited record places the spacecraft at Mars; the engineering profile keeps its instrument, power, communications, and navigation details separate from the mission narrative.

Documented result: Second Viking Mars landing. For viking-2, that result is the evidence users can compare with the original objective and source record.
