Photos: Space capsules under pressure

Two small-scale models of crew exploration vehicles, or CEVs, are undergoing extreme testing at the NASA Ames Research Center in Mountain View, Calif.

One CEV model is covered with pink, pressure-sensitive paint. It gives constant readings of pressure when inside the wind tunnel. The other measures forces being applied to the model inside the tunnel.

The research facility was shown off to a group of visitors on March 7, 2006.
