Transcript of Viking 1 and 2
Michelina and KaiyaVIKING 1 AND 2
Launched on August 20, 1975Reached Mars on June 19, 1976
VIKING 1:
Study air, surface, and to search for micro-organisms in soil.
Looking for good spots for Viking 2 to land on surface.
VIKING 1 GOALS:
16m diameter landerHoneycomb aluminum shock absorbersAeroshell18 nozzle design2 facismile camerasGas chromatograph mass-spectometerX-ray fluorescence spectrometer3 axis seisometer
VIKING 1 INSTRUMENTS:
Operated for 2,306 days. (6 years)Weathered basaltic lavaAll samples heated by GCMS gave off 1% of waterBiological experiments: Pyrolytic Release, Labeled
Release and Gas Exchange experimentSimilar to Antarctica
VIKING 1 RESULTS:
Launch: Sept. 9, 1975; Cape Canaveral Air Force Station, Florida
Land: Nov. 3, 1976; Utopia Planitia, Mars Began Orbiting: Oct. 5, 1976Mission end: April 11, 1980Two part- Orbiter and Lander
VIKING 2:
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 GOALS:
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
VIKING 2 INSTRUMENTS:
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
VIKING 2 RESULTS:
