"Mars Rover Explores Winter Wonderland on Sol 3905"
NASA's Mars rover Curiosity is facing power limitations during the winter season at Gale Crater, resulting in constrained science activities and drives. Despite a failed frost experiment, a second opportunity may arise later this week. The rover's planned activities for Sol 3905 include touch-and-go observations of a target called "Novo Paraiso," remote sensing of a dark-toned float rock named "Pico Phelps," and a drive towards Gediz Vallis Ridge to investigate new surface materials.
