Re: Rocket Lunches

Hey, I'm a believer in the Principle of Charity: interpreting what other people say in the most friendly and reasonable way. But I look at this sentence: "it's because we changed [Cassini's orbit] to allow closer passes on Enceladus to sample water that geysers spew out" and it's hard not to see a p...

Re: Rocket Lunches

My naive understanding is that there's really no such thing as a parking orbit for a small satellite. This is not correct in general; e.g. geostationary orbits around Earth are fairly stable; but it is indeed correct for a complex system such as Saturn, especially where Cassini was. I notice you us...

Re: Pure Data

I haven't poked around with pure data, but I have seen an interesting program along these lines. Chuck is basically a programming language for making musical notes and midi files. Another one to do this is Scribbletune . And there's a demonstration video of scribbletune which is pretty cool. I'll h...

Re: Rocket Lunches

My naive understanding is that there's really no such thing as a parking orbit for a small satellite. Between variable mass concentrations of whatever you're orbiting, and perturbations from other objects, the more time that goes by the more these influences add up. Without external intervention, ev...

Re: Rocket Lunches

I have some problems with this attitude, but it's an explanation worth knowing. I'd be interested in hearing you elaborate. :) Nothing cray-cray; I just don't want physical (especially human) exploration of other worlds discouraged by an unnecessary view of human activity as "contaminating" other p...
