Seems to be a more interesting and optimistic time for space exploration at the moment than we've seen recently - would like some progress on manned missions too though.
NASA launches armoured storm probes to the Van Allen belts
NASA has successfully launched two Radiation Belt Storm Probes into Earth's orbit to start a two-year mission to study the two giant donuts of plasma trapped in radiation surrounding the planet.

Re: Heavily Shielded for Radiation Protection
Fact Check. The Van Allen belts themselves are MUCH more dangerous than normal deepspace. Apollo astronauts were expected to stay in the command module for most of the trip.
When they did use the LEM (inferred from your 'skin' reference), they were certainly much-less-shielded than in the command module.

"Fact Check. The Van Allen belts themselves are MUCH more dangerous than normal deepspace. Apollo astronauts were expected to stay in the command module for most of the trip."
Absolutely. It is also a fact all Apollo astronauts took a calculated *substantial* risk that no major solar flare would hit them to or from the Moon (and since all trips were taken during a lunar day you'd get hit badly on the Moon in the LM).
I think the trouble is there has been *relatively* little surveying of the Van Allen belts over the years. I'm not sure if there have ever been more than one satellite on orbit at one time.
This sort of information in interesting in it's own right but could also help with making low thrust maneuvers more viable. This would be a *major* benefit to anyone launching a comm sat with a station keeping ion engine. Avoiding the need for an Apogee Kick Motor (roughly 25-33% of payload weight) would either mean a smaller launch vehicle ($ saved) or more station keeping propellant and/or more transponders -> bigger $$.
And it might help re-size the radiation shielding on the NASA MPCV

"The probes are also equipped with metal shielding and data filters to protect against interference."
So the aliens are here then! The Van Allen belts are the wake from the plasma drive of the ships that use our solar system as a rat run. Clearly NASA want more information on this, but are worried about the aliens trying to corrupt the data with viruses.
The only real worry is if the Hyperspace Planning Council decide that all this traffic is disturbing the locals, and so decide to build a hyperspace bypass.
