Nasa’s Cassini spacecraft has crashed into Saturn’s atmosphere after exploring the planet and its moons for nearly two decades. While there are many spectacular discoveries to look back on, it’s uncertain what’s next for human exploration of the the planet and its satellites. Monica Grady considers what the next mission could look like, and suggests we might want to call it “EnTiRE” – Enceladus and Titan Research and Exploration.
You can catch up on more in-depth Cassini coverage from scholars around the world here. Meanwhile, back on planet Earth, our authors listen to the music of the Vietnam War years, sample the dubious air
we breathe underground, and explain how bacteria travel the globe.
