"NASA's Mars Exploration Turns Setbacks into Success with Sol 3940"

NASA's Curiosity rover faced some challenges during its mission on Mars, with one wheel perched on a rock, making it unsafe to unstow the arm and perform contact science. However, the science team made the most of the situation by increasing targeted science observations and acquiring imaging of the Gediz Vallis ridge to understand its formation. They also examined an elongate resistant feature called "Olympia" and analyzed resistant bedrock with APXS. The team plans to continue documenting the immediate vicinity of the rover and will take a Navcam dust devil movie before driving away.
