DESTINATION MARS. FIRST STOP... THE ARCTIC? Before heading to Mars, space scientists and engineers are traveling to the Canadian Arctic
to live and work in the Haughton impact crater. Its climate and geology are as Mars-like as
can be found on arth-cold temperatures, low precipitation, and permanently frozen
impact-ejected rubble. The Haughton crater provides opportunities to test new
technologies and field procedures and to study human behaviors that result from extended
contact in close quarters. The knowledge gained from these investigations is being used to
plan, design, and ultimately to conduct the first manned and continued robotic missions to
Mars and other planets and their moons.

Explanation:

sis. it's been a while since a read that and had that class so i can't answer for u

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
