NASA Wants to Toss 10,000 Tiny Probes Directly Into Saturn's Rings

Cassini, NASA’s last major mission to Saturn, famously plunged to its fiery death in the gas giant’s atmosphere at the end of its mission. It had captured more accurate in-situ data of the Saturnian system than any mission before or since. But there’s one particular part that it couldn’t directly approach - Saturn’s rings. But NASA very obviously wants to take a nice up-close look at them, as they have recently funded a NASA Institute for Advanced Concepts (NIAC) Phase I grant to send a swarm of 10,000 highly expendable “femtosatellites” to get up close and personal with the most spectacular rings in our solar system.
