I miss the times when I grew up, where such kind of news would inevitably lead to speculations and very detailed artistic impressions of what a human colony in Mercury's terminator zone would look like.

How many dumb ideas that we had as kids turn out to be good

Cool - but "A Mercury Rover Could ..." presupposes a soft landing on Mercury.

Try asking an aerospace engineer about the delta-v requirements for that. Mercury has no atmosphere - so you can't aerobrake, as we do on Mars.

Absolution Gap[1] has a plot device similar to this. If you like hard sci-fi, Reynolds belongs in your queue.
