The 32nd Annual Lunar and Planetary Sciences Conference — held in Houston from March 12 through 16 — like all the LPSCs before it, was a major scientific powwow at which scientists from the world over presented hundreds of papers and posters on the geology, meteorology and chemistry of the other worlds and objects in our Solar System, from giant planets down to meteorites. As to be expected a major theme of this year’s LPSC was the ongoing debate as to just how much liquid water Mars had on or near its surface during its earliest days, and how much it has now.
