Name one interesting fact about mars.
Do you think the Moon could retain an atmosphere of nitrogen for the age of the Solar System? Explain why or why not
Moon dust is dangerous to astronauts because
it is highly radioactive
it will explode when exposed to oxygen
it consists of sharp, jagged particles which are dangerous to inhale
it contains large amounts of toxic arsenic
The Biosphere 2 experiment was
an experiment performed on Mars in the 1990's to see whether small-scale terraforming might be feasible
a prototype "space colony" in Low Earth Orbit that supported a crew of 6 for nine months
a successful attempt to grow crops hydroponically to see if space colonists could feed themselves with home-grown food
a largely unsuccessful attempt to create a completely self-contained habitat on Earth
