Space Forum / Shuttle / January 2008radiation
We hear a lot about radiation in space, and a lot of what is out there is coming from a long way away in the form of gamma ray bursts. Unlike the radiation from the sun, there is no warning at all, and I just wondered how much this has an impact on Shuttle and station crew. Or is the orbit pretty well screened from this sort of event? As an aside, I keep reading about the events which cause these bursts may cause gravitational waves, but I've not seen anyone prove these waves actually occur, or if they lag or precede the burst if they do. OK, they are supposed to exist, but....! I think the powers that be have a lot of serious thinking to do if they intend to base people out on our moon. Incidentally, I think we need a name for our moon. All the other planets with moons have had them named, yet ours is just known as 'the moon'. Lets give it a name!

For all intents and purposes, gamma ray bursts are extremely distant and too weak to be any kind of a threat. > As an aside, I keep reading about the events which cause these bursts > may cause gravitational waves, but I've not seen anyone prove these > waves actually occur, or if they lag or precede the burst if they do. The gravitational waves are even weaker; scientists are struggling to find ways to measure them. They may or may not appear with a specific gamma ray burst event as the possible causes may be several. --Damon >> We hear a lot about radiation in space, There has recently been some discussion of radiation beaming from stellar collapse as a possible cause of planetary extinction, along the lines of asteroid collisions, climate change, a few others. The lethal radius of lethal radiation is considerable, say 500 light years. I call it the charcoal briquette effect. As far as gravity waves, I think these are more of an interest to cosmologists and theoretical physicists and not so much in terms of relating to a specific astronomical events.

Lets > give it a name! > > Brian Back before the space age, the word "satellite" was used to describe natural objects that orbit planets. But since, that word has evolved to mean "artificial orbiting object" and the lower case "moon" is used to describe natural objects that orbit planets. But upper case "Moon" means our (Earth's) moon. > We hear a lot about radiation in space, and a lot of what is out there is > coming from a long way away in the form of gamma ray bursts.

According to everything NASA/Apollo, our atmosphere and even the magnetosphere doesn't filter out hardly anything of X-rays or gamma, as well as our naked moon isn't the least bit anticathode worthy, therefore LEO EVA's and even moon surface EVAs are of no significant radiation concern whatsoever. You buy any of that? - Brad Guth > Incidentally, I think we need a name for our moon. All the other planets > with moons have had them named, yet ours is just known as 'the moon'.
