Nasa’s Mars site:

Mars needs YOU! In the future, Mars will need all kinds of explorers, farmers, surveyors, teachers . . . but most of all YOU! Join us on the Journey to Mars as we explore with robots and send humans there one day. Download a Mars poster that speaks to you. Be an explorer!

And:

Night owls welcome! If you lived on Mars’ moon Phobos, you’d have an office with a view, mining for resources with Mars in the night sky. Settlers below on Mars would see Phobos rise and set not once, but twice in one day!

This is some compelling prose, feels like part of a beloved sci-fi set. The accompanying posters were originally developed for the Kennedy Space Flight Center’s visitors complex. Now they can be yours, free.
