...space travel survivable at all? Because all speed is relative. A satellite orbiting Earth may be moving at 17,500 m.p.h., but so is every other object in the same orbital corridor. Relative to one another, they're standing still. If one happened to speed up to 17,505 m.p.h., the most it could do is nudge another ship at 5 m.p.h. Attaining orbit is like entering an expressway: the tricky part is merging; once you're there, all you have to do is maintain your speed, and you'll be fine.

...trouble comes when speed - or worse, the angle - of orbit changes. Things in higher orbits move more slowly than things in lower ones. A dead satellite or one that has lost gyroscopic control could go tumbling down to lower and lower orbits, colliding with objects moving at different speeds along the way. Similarly, the International Space Station and its three astronauts do, in theory, lie in the path of the debris created by Tuesday's collision, and while international space officials believe the danger to the crew is low, they do not rule...
...Think about two cars colliding in an intersection," says Nicholas Johnson, head of NASA's Orbital Debris Program. "The individual speeds [of the satellites] were about 17,000 m.p.h., but the collision speed was 26,000." (See pictures of meteors that hit Earth...
Harvard must remember its obligations as an institution committed to research, despite the financial situation. We hope that the university will continue full speed ahead and will soon be breaking ground on the other side of the Charles...
...Rogers said. The Raiders have not experienced an ideal season, but the Crimson is not taking them for granted. “Any team can come out and beat a team on a given night,” Biega said. To prepare for the quickness and speed of transition the Raiders possess, Harvard has put a real focus on the power play during practices. “Special teams are a make-or-break part of the game,” Biega said. While the rivalry between Harvard and Colgate is not at the same level as the one with...
