Most of the particles in space are traveling at hyper speeds.
Correct me on my math here, I'm think I'm right.
If a tether and a sail was anchored here on our planet, then it would still be travelling at the same linear speed that the earth travels at around
the sun; about 66,00 miles per hour. A grain of sand simply floating in space and not moving at would still have an impact velocity of 66,00 miles
per hour. The grain of sand would have the impact kenitic energy of roughly 10,000 ft- pounds. After a while, your sail would be shredded to bits.
This is a very real concern to NASA and ISS, not only are there naturally occuring particles, but we, men, have left all kinds of junk floating around
