A huge deposit of porous rock straddling the Martian equator likely formed as a result of explosive volcanoes erupting three billion years ago that were powered by climate-changing volatile gases trapped in the red planet’s interior
While excitement among planetary observers is growing for the best views of Mars for 15 years (Martian dust storms permitting) in late July, there’s still one prior planetary treat: the opposition of Saturn on 27 June, which coincides with a close lunar conjunction.
