That depends entirely on the supply of cash. There are no unsolvable problems between here and there.
Can NASA colonize Mars in 100 years? Highly unlikely without significant changes to our civilization. Still, there are interesting problems whose investigation can benefit life on Earth.

Thanks!
I write a blog, phobosorbust.blogspot.com, on the subject of human colonization of space. I try to focus on specific problems and how they might be solved with current or near-term technology, as well as comment on current events in the industry. Nothing speculative or fringe, that...
Much better explanation, thank you. I shouldn't have used a term with a specific technical meaning in a more general sense.
Does that suggest that once the force of impact between dust particles becomes high enough to break them apart that the system would experience a significant increase in...

If it weren't for tuition money I'd be a physicist today. Instead, I try to read all I can and write about space in my free time. Hope I can be helpful and give a little back to a community that has already answered many of my questions (via...

These are large populations of either gas molecules or dust particles in a vacuum, bound only by gravity. That is a very different proposition from gas or dust in a box which can be squeezed and measured on a laboratory bench.
Let's assume the initial condition is an...
