Europe's comet chaser Rosetta reactivated after 2 years of hibernation

The video discusses the Rosetta spacecraft's mission to study comets, which scientists believe can provide insights into the origins of life on Earth. Rosetta orbited Earth and performed a slingshot maneuver around Mars. Due to its distance from the sun, it was put into power-saving mode in 2011, halting communications. The spacecraft is set to be revived on January 20th, with its systems reactivated to continue its mission. As Rosetta nears Comet 67P, it will deploy a lander named Philae to gather data.
