One such example is the top secret mission to a previously-unknown planet just outside our solar system. A probe launched 20 or 30 years ago finally reached the planet, but could not land on the strange soil there. Instead, the rocket hovered and collected a sample of the soil, and "hyperspaced" it back to Earth.
With the volume of backed-up work, NASA needed to make an alternative plan to report on the planet's unusual soil and propose possible new vehicles that might land on the planet's surface. Quick studies by innocent fourth graders in Joplin, Missouri seemed an appropriate choice. After all, who would suspect?
NASA wanted to know if this soil was a solid or a liquid, and it turns out it had properties of both states of matter. Indeed, this was a unique, non-Newtonian substance! What possible vehicle could land on such without sinking?
