I went to the Science Museum Monday.
I went through the new "Hubble Space Telescope : New Views of the Universe" exhibit.
I saw the new IMAX film Roving Mars.
The exhibit has some interesting images of images from the HST.
The film showing some interesting problems that were solved to get the two Mars rovers, Spirit and Opportunity, to the surface of Mars in one piece.
For example, the rovers got heavier as they were being built and tested at the jet Propulsion Laboratory.
Research and development went in to get a parachute to use on a rover falling at MACH 2 and inflatable air bags to land on the surface.
Also the two sites were the rovers landed were discussed.
One site showed signs of water on Mars above ground form a long time ago.
