Viking 1 was launched on August 20, 1975 and arrived at Mars on June 19, 1976. The first month of orbit was devoted to imaging the surface to find appropriate landing sites for the Viking Landers. On July 20, 1976 Viking Lander 1 separated from the Orbiter and touched down at Chryse Planitia. Viking 2 was launched September 9, 1975 and entered Mars orbit on August 7, 1976. Viking Lander 2 touched down at Utopia Planitia on September 3, 1976. The Orbiters imaged the entire surface of Mars at a resolution of 150 to 300 meters, and selected areas at 8 meters. Viking Orbiter 2 was powered down on July 25, 1978 after 706 orbits, and Viking Orbiter 1 on August 17, 1980, after over 1,400 orbits.
So, 30 years later and now all these wanna be scientists will offer up there opinions. Wonder how much in government grants they will be seeking to keep their theories going. The whole surface of Mars was imaged and they are just now getting around to making summations. I got one. It is a dirt bowl full of rocks. Prove me wrong. Oh, I should qualify for a huge govenment grant for my summation.
"'The findings are important because they tell us that Mars has experienced big climate changes in the past, the kinds of climate change that led to the Great Ice Age here on Earth,' said Head, the Louis and Elizabeth Scherck Distinguished Professor at Brown."
Do you prefer the incessant crying about anthropogenic greenhouse gas explanation for the apparent global warming?
