Re: Ow!
The flowing Martian water thing has been evident for over a decade. Arthur C Clarke actually used the idea in a Venus Prime story before the lineations were known. I suspect that unless the "announcement" is made soonish, they will wait until the first human landings before "discovering" that huge areas of Mars are covered in dust-mantled glaciers. Those circular karsts have to be due to something other than limestone being dissolved by ground water. Sublimating ice (methane or water) is the next best explanation. Mars is adiabatically dry and cold because of the elevated southern hemisphere and polar regions. Look for the giant alien reactor there.
