An illustration of NASA’s Perseverance rover landing on Mars. NASA, China, and the United Arab Emirates each have a mission speeding towards Mars – all set to arrive in February. NASA’s Perseverance rover is equipped to sniff out signs of alien life, while China’s Tianwen-1 rover could find underground water. The UAE’s Hope orbiter aims to make a global map of the Martian climate. After six months of careening through space, three sets of robots finally have Mars in their sights. The missions — from NASA, China, and the United Arab Emirates — are set to reach the red planet this month, either falling into orbit around Mars or landing on its dusty red surface. Once there, they aim to search for signs of alien life, scan for underground reservoirs of water, and map the planet’s changing seasons.

The Hollywood film Greenland, which will premiere on video on demand on Dec. 18, looks at the effects of the fictional yet convincing Comet Clarke, a large comet that has split into still-hefty pieces. In the movie, the comet takes scientists by surprise because it came from another solar system, making its orbit more difficult to predict echoing the emerging science of interstellar objects we ve spotted near Earth.
