TL;DR

Did you know that NASA is considering sending a massive cloud of tiny robots to crash through the rings of Saturn? This approach marks a shift from building one large, expensive spacecraft to deploying thousands of cheap, disposable sensors. If a few hundred break, the mission continues without a pause. NASA recently provided funding for a study led by Michael Rubenstein to explore this swarm concept. Researchers call these tiny machines femtosatellites because they weigh less than 100 grams. You can imagine a device that fits in the palm of your hand but carries enough hardware to talk to Earth from millions of kilometers away. The project received part of a 3.2 million dollar award pool in 2026 - this money supports Phase I of the NASA Innovative Advanced Concepts program. Engineers are currently testing if they can steer 10 000 of these tiny probes at once to act as a single, giant scientific instrument.
