Solid Buckyballs in Space

Q: What happens when an interstellar space craft or inner solar system space craft collides with a relatively small solid buckyball cluster?

A: A dent in the hull and minor deflection from course.

"Astronomers using data from NASA's Spitzer Space Telescope have, for the first time, discovered buckyballs in a solid form in space. Prior to this discovery, the microscopic carbon spheres had been found only in gas form in the cosmos."

T-L Center Pivot Irrigation System

The sprayers under the pivot boom are positioned above the final crop head height. These sprayers are a recent innovation delivering moisture closer the ground. The pivot irrigation practice in western Nebraska requires significant amounts of water pumped from the Ogallala Aquifer that is nominally threatened by the Keystone XL Pipeline.
