The next day, the Russians will conduct the first of two "suitability tests" to determine whether or not the astronauts will be able to withstand the rigors of a lunar environment. The first test will ask the astronauts to demonstrate their ability to "brawl" and "rebuff" a "contradictory" question. The second test will give the astronauts three points to watch for in order to maintain their health in the harsh environment of the lunar orbit.
