Tiny microthrusters developed at MIT will be used to maneuver very small satellites.
(Mini ion thrusters)
Lozano’s design is a flat, compact square — much like a computer chip — covered with 500 microscopic tips that, when stimulated with voltage, emit tiny beams of ions. Together, the array of spiky tips creates a small puff of charged particles that can help propel a shoebox-sized satellite forward.
“They’re so small that you can put several [thrusters] on a vehicle,” Paulo Lozano, an associate professor of aeronautics and astronautics, says. He adds that a small satellite outfitted with several microthrusters could “not only move to change its orbit, but do other interesting things — like turn and roll.”
These independently powered and maneuverable devices are like tiny versions of the pushpots in Murray Leinster's 1953 novel Space Tug.

Illustrating Classic Heinlein With AI
'Stasis, cold sleep, hibernation, hypothermia, reduced metabolism, call it what you will - the logistics-medicine research teams had found a way to stack people like cordwood and use them when needed.'
Deflector Plasma Screen For Drones ala Star Wars
'If the enemy persists in attacking or even intensifies their power, the density of the plasma in space will suddenly increase, causing it to reflect most of the incoming energy like a mirror.'
