What's up in the night sky for January? Jupiter is at its biggest and brightest all year, Saturn and the Moon get close for a conjunction, and the Beehive Cluster buzzes into view! | NASA Jet Propulsion Laboratory

Earth-based twin of NASA’s Perseverance rover, being tested at NASA’s Jet Propulsion Laboratory. While Perseverance explores Mars, its twin helps engineers here on Earth test driving commands, software updates, and problem-solving scenarios before they’re sent millions of kilometers away. Every safe move on Mars starts with careful testing on Earth. This is how NASA makes interplanetary exploration possible.
