Capturing Solar Images in the Extreme Environment of Space
Imagine trying to take pictures or make optical measurements on a cloudless day beneath the blistering onslaught of 13 suns. This is the equivalent reality for the European Space Agency’s (ESA’s) Solar Orbiter and NASA’s Parker Solar Probe (PSP), the latter of which is currently operating in temperatures of almost 1640 K in the inhospitable environment around the sun. “Probably the single important aspect of both of these missions is that they are going to regions of space...
