CALGARY, ALTA. It s the stuff of both cheesy sci-fi movies, and high-brow academic research…Is there (or was there) life on Mars? A trio of Martian missions arriving at the red planet this month will likely reignite the debate. The United Arab Emirates (UAE) Amal orbiter has already arrived, and is orbiting Mars, as has the Chinese Tianwen-1 combination orbiter which is carrying a landing module as well. NASA s Perseverance rover is scheduled to land on the surface of Mars on Feb. 18. All three missions are examining Mars to further our understanding of what is considered he only other possibly habitable planet in the solar system.
