In terms of containment right now, the top cap is drawing oil and gas to the surface to -- from the LMR -- the lower marine riser cap to the Enterprise.
And what I mean by that is we believe that the cap will work just fine in the containment, that through a couple of different areas, that cap will take oil to the surface as well as to the choke and kill lines.
If a large body of water once existed on the red planet, the remainder of the water must now either be stored below the surface and in the much smaller south polar cap, or have been lost to space.
This has enabled scientists to estimate the volume of water in the ice cap and speculate that much of the planet's original water is either hidden below the surface or missing.
