drag in space

Well, vacuum is not exactly an emty space. If we have a spacecraft moving at sublight velocity, it can encounter some resistance even at very low concentration of particles in space. Does anybody know the website that can provide an estimate ? I'm just thinking that though most SE shipsets are sleek and aerodynamic for purely aesthetics reasons, there might be some sense in such design ?

Re: drag in space

Here are some good ones (used a google search for "atoms per cubic meter"):

Re: drag in space

WHEW!
I was afraid this thread was going to talk about some hairy ship wearing a dress.

Re: drag in space

Ain't gonna happen.
High heels, big wigs, and short dresses is not advisable in Zero-G conditions.

Sorry Oleg.
Can't help.

Re: drag in space

There is not enough mass in space to cause enough drag to make aerodynamic designs any better than non-aerodynamic designs.
