By using photo-spectrometers,UV analyzers, Hubble telescope,radio analysis, ambient radiation comparators. And a vast array of equipment way above my head.

Several landers have touched down on Mars. Aboard these are special instruments called gas spectrometers can "sniff" the atmosphere and analyze its chemical content. The results are radioed back to Earth.
Before any of those landers went to Mars though, it was possible to analyze the reflected sunlight coming from Mars which revealed the chemical composition of its atmosphere.

There have been already many explorations of Mars and two NASA robots are still operational on the Mars surface and they continue transmitting scientific data to the Earth.

spectroscopy. you take the light from the pictures or colors and send them through a digital prism and you get a rainbow of color. there are little tiny black lines in the rainbow and those black lines represent the gases and elements present in the objects in the pictures.
