The Ythrian Biosphere

"Wings of Victory."

The text partly answers a question that I asked in the preceding post. The Olga crew observes Ythri from space and sends robot probes to the surface. Thus, they know that:

Ythri receives about the same solar radiation as Earth;

the air is breathable by human beings;

there are bodies of water;

the life is chemically similar;

none of the captured microorganisms is a serious threat;

there are woods, lakes, plains and mountains.

I still think that human explorers would be slow to expose themselves directly to that air and those organisms. The unknown is always with us. In the film, E.T., when someone from NASA investigates the extra-terrestrial that has landed on Earth, he goes in a spacesuit. Maybe the E.T. has brought his atmosphere with him! Who knows? We know almost nothing yet.
