They want to build the telescope on the far side of the Moon, to shield it from terrestrial (man-made) radiation. Is this premise in peril by other Moon missions? For example, do NASA or other space agencies have plans to build other bases on the far side of the moon, which could emit radiowaves which affect the LCRT?

A spherical structure nearly one billion light-years wide has been spotted in the nearby Universe, dating all the way back to the Big Bang

“The abundance of methane and carbon dioxide, and shortage of ammonia, support the hypothesis that there may be a water ocean underneath a hydrogen-rich atmosphere in K2-18 b. These initial Webb observations also provided a possible detection of a molecule called dimethyl sulfide (DMS). On Earth, this is only produced by life. The bulk of the DMS in Earth’s atmosphere is emitted from phytoplankton in marine environments.”
