Writing a Factual Book About Mars

The history of Mars is simultaneously obvious and hidden. We've only had a clear idea of what Mars looks like since the late 1970s. I think we're not going to put foot on Mars until probably the 2040s, possibly the 2050s. It will take nine months to get there using our current technology. The longest space trip we've managed so far is Earth to Moon which takes three to four days. And we've been in space for years now but that's a whole different ballgame from taking it at International Space Station.
