Is it to study radiation effects in space or just grant money for creating more papers
The problems with all the spectrums in space has been studied. Shielding, manufacturing radiation hardening resistant process, error correction design, redundancy. - even dual mirror channel architecture with fault error design between the two was used in military hardware since the beginning.
We also have facilities that does this here on earth such as https://www.bnl.gov/nsrl/ . Someone convinced the grants team that they need real time data.
I think the biggest problem is radiation emitting contamination getting into our electronics (as well as all man made products including shielding) manufacturing which we have not been able to completely rid of since the beginning of the above ground nuclear tests and more recent nuclear disasters (Chernobyl and Fukushima)
