How do Americans get ready to work with Russians aboard the
International Space Station? They take a crash course in culture, language
and protocol at Russia's Star City.
Sky watchers in Europe, Asia, and parts of Alaska and Canada
will experience a partial eclipse of the Sun on Saturday, May 31st.
Before man travels to Mars, NASA hopes to design new engines
that will let us fly through the Solar System more quickly. The proposed
VASIMR engine would do that.
Compared to earlier spacecraft, the International Space
Station has many luxuries, but laundry facilities are not one of them.
Instead, astronauts have other options.
