Study air, surface, and to search for micro-organisms in soil.
Looking for good spots for Viking 2 to land on surface.

Orbiter: High resolution map of the planet -> take pictures Signs of Life Help direct the lander with its landing
Lander: Signs of Life Close up examination of the surface -> take pictures

Orbiter: Imaging System -> Camera Atmospheric water detector -> Signs of water Infrared thermal mapper -> Detect emitted and reflected
radiance of MarsLander:
Imaging System -> Camera Gas chromatograph mass spectrometer -> composition of
the surface Seismeter ->geological activity (dead planet?) X-ray fluorescence spectrometer -> composition of the
surface Biological laboratory ->signs of life or possibility of life Weather instrument package -> atmosphere Remote sampler arm -> pick up objects for closer
examination

Didn’t find life but found elements necessary for life Carbon, Nitrogen, Hydrogen, Oxygen and Phosphorus
High Resolution PicturesMapped the planet Soil Analysis:
Basaltic Lava based, high levels of Siliconand Iron, Magnesium, Aluminum, Sulfur, Calcium and Titanium
