chemical composition of the atmosphere of Mars has been changed by the comet that was grazed in October. According to a revelation made by NASA Friday, the passage of the comet Siding Spring to just under 136,000 miles from Mars, October 19, triggered a series of events.
The dust of the Comet bombed the upper layer of the sparse atmosphere of Mars and has literally changed the chemical composition, says NASA says in passing, the tail of the comet dumped thousands of pounds of dust in the atmosphere Mars. An amount far greater than what was originally planned.
ions of iron, magnesium and sodium were detected by measuring instruments NASA thinks that this type of event occurs once every 8 million years ago.
