Just Four Robots Could Deploy a Huge Radio Telescope on the far Side of the Moon By Nancy_A
like the lunar far side. The two-wheeled tethered rovers can even work over steep and rugged terrains and even rappel down highly sloped terrain. JPL says the tethers provides mechanical support on steeper slopes and delivers power and communication from a host platform. Hallinan and team have designed the tether such that the instrument/antenna is also integrated within.
The rovers would spool out four separate 12-km-long tethers, each with 64 remotely powered electronics nodes. The team analyzed four different designs for the array , and the winner for the best performance was the four-arm spiral which “required the shortest rover trajectories, which implies easier accommodation of a smaller tether spool and less mass burden per rover.”
“We also were going to us multi-mission radioisotope thermal electric generator to provide power to the base station, but the Blue Moon lander has solutions that allowed us to move in a new direction for that also,” Hallinan said. “As you can see fromHallinan said that one thing that may not be obvious in this relatively simple design is that this array is incredibly sensitive at very low radio frequencies.
