How did life begin on Earth? Our Dragonfly mission aims to find clues by exploring Titan, Saturn’s largest moon. As a pristine chemical "laboratory," Titan offers a unique window into the processes that may have led to complex molecules and the first signs of life! More:

Escaping to Mars if (or when) Earth becomes too hot under our feet is not a good idea, argues astrophysicist Caleb Scharf🌎. It is at best no less risky an alternative, and for the same money, we could decamp to artificial habitats: buff.ly/Q3AeLoj

In 1962 the Ranger 3 spacecraft missed the Moon and instead placed a half-meter diameter wooden sphere into orbit around the Sun, where it likely is to this day. #TheGiantLeap tinyurl.com/29j6bktf
