“Our technique provides a non-contact and long-distance pulling approach, which may be useful for various scientific experiments,” said Wang. “The rarefied gas environment we used to demonstrate the technique is similar to what is found on Mars. Therefore, it might have the potential for one day manipulating vehicles or aircraft on Mars.”
Space exploration is an increasingly energy-hungry endeavor. Orbiters and fly-by missions can perform their tasks using solar power, at least as far out as Jupiter. And ion drives can take spacecraft to more distant regions. But to really understand distant worlds like the moons of Jupiter and Saturn, or even the more distant Pluto, we’ll need to eventually land a rover and/or lander on them just as we have on Mars.
Those missions require more power to operate, and that usually means MMRTGs (multi-mission radioisotope thermoelectric generators.) But they’re bulky, heavy, and expensive, three undesirable traits for spacecraft. Each one costs over $100 million. Is there a better solution?
Stephen Polly thinks there is.
Polly is a research scientist at the NanoPower Research Laboratories at the Rochester Institute of Technology. His work focuses on something most of us have likely never heard of: the development, growth, characterization, and integration of III-V materials by metalorganic vapor phase epitaxy (MOVPE).
