The problems with colonizing other worlds can be read here: Humans Will Never Colonize Mars.
It’s a bucket of ice water to dump on the head of anyone who optimistically thinks it will happen. It may happen, centuries from now. More likely places like Mars will be colonized by robots that will do a lot of the activities we once expected humans to do.
It’s not explicitly stated, but if you read this: If you think NASA is frustrated with SpaceX, you’re probably right in Ars Technica, then you may draw the same conclusion. It seems SpaceX is taking advantage of its partnership with NASA to position itself to get the point where it can get by without it and eventually compete with the space agency.
If that was not the case, then I would expect SpaceX to stick to missions that were separate from NASA and supportive of NASA. Instead they seem to be trying to compete with NASA for the same missions.
It’s a tricky call for SpaceX: if they are not careful, they could ruin their partnership and find themselves without a steady source of income to fund their ambitions. I’m all for both NASA and SpaceX both being viable for the long term. Let’s hope that happens.
It’s great that SpaceX has put travel posters to Mars among their other photos on flickr (SpaceX Photos | Flickr). Of the three I saw, the one above was the one I liked the best. Head over to Flickr and check out the others.
It’s fun now, but perhaps such advertisements will be less fantastical before the 22nd century.
