This is a slightly different topic, but aside from bringing some fancy laptops along, I doubt they would do anything substantially different if Apollo was to be repeated today. We know a little more about the environment, but not all that much can be done other than shield against normal conditions and take your chances on the solar events.
Given that there was only about 17% of a single solar event during the entire Apollo program, they had pretty good odds of getting away with it, and indeed they did. Today, in the risk-averse environment that has grown up, I doubt they'd dare... *shrug*

Um....so when the ESA's SMART-1, or the Japanese Hiten reached lunar orbit, why didn't they mysteriously explode from all the stuff NASA had been hiding from the rest of the world? How is it that a half-dozen nations are able to put satellites up without asking NASA to do it for them? Do you really think space exploration is a private playground? Manned space exploration beyond earth orbit s a private playground . The moon is in Earth orbit...

So you haven't contacted the radiation experts yet, and told them how wrong they are?
It'd be interesting, Turbo, you being able to correct some of the world's foremost experts.
Until that time, please forgive me if I accept their in-depth studies over your claims.

Events like the emission of charged particles, alpha, beta and gamma radiation.
And the flux and energies of these are?
Actually I'd just like to see any qualified work referencing the sun as a dangerous emiter of Alpha or/and Gamma radiations full stop.

Aww, shucks, now I'll never know why he brought up that it was an emitter of Alpha and Gamma if he didn't believe they were of deadly quanities. Too bad, never mind.

Unfortunately, the preciseness of predictions of space weather effects is still poor. Solar energetic transients, i.e. flares and coronal mass ejections (CMEs), occur rather spontaneously, and we have not yet identified unique signatures that would indicate an imminent explosion and its probable onset time, location, and strength. The underlying physics is not yet sufficiently well understood. Solar energetic particles, accelerated to near-relativistic energies during major solar storms arrive at the Earth’s orbit within minutes (see, e.g. Garcia, 2004) and may, among other things, severely endanger astronauts on the way to the Moon or Mars. But we have no appropriate warning tool yet!www.ann-geophys.net/23/1033/2005/angeo-23-1033-2005.pdfWhat? Don't they know about the SPAN? We had this problem licked back in the 60's, for Pete's sake! Turbonium, you are still missing the point about the difference between prediction and taking measures after an SPE has been detected. It's the difference between predicting that a car is going to come over the hill before you see it before you cross the road and hurrying out of the road when you first see it appear heading towards you.
