On the cover
Weapons in Space: Should Anyone Care? Is this our legacy for future generations?

The public must claim the right, and own the responsibility, to question the motives and assumptions of those who are pushing for weapons in space. Because of our physics training and our distribution throughout the larger society, Sigma Pi Sigma members are well-placed to raise a discussion of this topic that links applications of physics to the broader sweep of human values.
