Viking 1 and 2 Michelina and Kaiya
Viking 1: • Launched on August 20, 1975 • Reached Mars on June 19, 1976
Viking 1 Goals: • Study air, surface, and to search for micro-organisms in soil. • Looking for good spots for Viking 2 to land on surface.
Viking 1 Instruments: • 16m diameter lander • Honeycomb aluminum shock absorbers • Aeroshell • 18 nozzle design • 2 facismile cameras • Gas chromatograph mass-spectometer • X-ray fluorescence spectrometer • 3 axis seisometer
Viking 1 Results: • Operated for 2,306 days. (6 years) • Weathered basaltic lava • All samples heated by GCMS gave off 1% of water • Biological experiments: Pyrolytic Release, Labeled Release and Gas Exchange experiment • Similar to Antarctica
Viking 2: • Launch: Sept. 9, 1975; Cape Canaveral Air Force Station, Florida • Land: Nov. 3, 1976; Utopia Planitia, Mars • Began Orbiting: Oct. 5, 1976 • Mission end: April 11, 1980 • Two part- Orbiter and Lander
Viking 2 Goals: • 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
Viking 2 Instruments: • Orbiter: • Imaging System -> Camera • Atmospheric water detector -> Signs of water • Infrared thermal mapper -> Detect emitted and reflected radiance of Mars • Lander: • 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
Viking 2 Results: • Didn’t find life but found elements necessary for life • Carbon, Nitrogen, Hydrogen, Oxygen and Phosphorus • High Resolution Pictures • Mapped the planet • Soil Analysis: • Basaltic Lava based, high levels of Silicon and Iron, Magnesium, Aluminum, Sulfur, Calcium and Titanium
