John Timmer talks about the New Mars Rover over at Ars Technica
When NASA announced its plans for future explorations of Mars, there was a sense of disappointment in some quarters, since it featured a rover much like Curiosity. But NASA made clear that it was only using the proven technology of the vehicle itself; the instruments it carried would be all new, and shaped by both the advancement of technology and the experience of past missions.
Today NASA announced exactly what instruments the mission—currently called Mars 2020— will carry. They included hardware capable of making a more directed search for organic chemicals on the red planet, which could be evidence that life existed there in the past. And it will also carry an experiment designed to test our ability to produce oxygen for future manned explorations of Mars. The rover will also gather and cache samples to be picked up and returned to Earth by a future mission.
