NASA's 20-G Centrifuge Machine
Roland Piquepaille writes "Scientists from NASA and two U.S. universities are using a 20-G centrifuge machine that can simulate up to 20 times the terrestrial gravity to evaluate the effects of hypergravity on humans. This 58-foot diameter centrifuge has three cabins, one for humans -- limited to 12.5 G -- and two for objects and flying hardware. The goal of these experiments is to reduce the adverse effects that space travel can have on astronauts' physical heath. But by studying the health benefits of exercise on astronauts, the researchers also hope to help the rapidly growing senior population who, like astronauts, doesn't exercise much.

The word "terrestrial" comes from the Latin word terra "Earth" (in turn from PIE *ters- "dry [ground]", see Sihler's New Comparative Grammar ). While arguing from etymology is not always valid, I daresay that in this case if one simply says "terrestrial gravity", it's logical to assume to refers to the Earth's gravity, and not that of the moon or other planets, which have their own appropriate adjectives.
I think the pressures they are referring to would be experienced during launch, not during spaceflight.
