Here we present a discussion on such parameters, old and new, and ask how much we really understand them.

A delay would add millions to the cost of the mission, disrupt the intricate space shuttle schedule, and anger researchers eager to do science. But as the long-time program scientist of the Hubble Space Telescope effort, whose faulty mirror had to be corrected in space, Weiler knew that haste might have even more serious consequences. His instincts told him to wait. “I overruled three independe...
