Such comets were born during the formation of our solar system and are older than Earth itself. As Comet Siding Spring passed by Mars, it left behind a trail of gas and dust. Using space and ground-based telescopes, along with NASA’s fleet of Mars orbiters and rovers, scientists will study the composition of the comet and the effects of its gas and dust on the Martian atmosphere.
