Mars is obviously a stepping stone for open space or other planetary systems.
- abecedarius 8y agoThere are asteroids about as close or closer in delta-V terms. Mars is the easiest other planet, but planets just aren't as useful as asteroids and comets right now, because of those pesky giant wells they live in. And Mars in particular is better left pristine until we've had a really good look for signs of life.
