As someone who's been thinking about space since I was 4, in 1978, if (theoretically)  I can't go, I don't care anymore. In other words, continuous robotic exploration is uninteresting. Yes, there's great science done but if you land a geologist in Mars (s)he will discover more in a five days than opportunity did in five years. AND (s)he will be making way for humans to LIVE on Mars.<br>So I want humans on Luna and Mars doing science as well as just living and creating not just more volume for more people but volume for entire biomes off Earth.<br>Rovers and orbiters are useful tools. But as long as they are not sentient, they are tools to make way for humans.
