...better than allowing the invisible killers to linger undetected for days, exposing ever more people to infection. Also, it makes it possible for newly infected people to seek prompt treatment. "You can usually treat things like anthrax fairly well within the first day," says Richard Langlois, senior biomedical scientist at Livermore. "Once you have symptoms, it's very difficult...
...m.p.h. And that movement will not take place in anything like real time. Controllers will plan in advance any expedition the rovers attempt, then transmit an entire bundle of instructions, telling them every turn they are to make on the trip. Says Joy Crisp, the project's lead scientist: "In the morning, after each rover has woken up and gotten some sun on its solar panels, we'll send up a set of commands with instructions for what it's supposed to do the rest...

Says Chu Shulong, a political scientist at Tsinghua University in Beijing: "China is more concerned about a crisis spinning out of control." Few anywhere want that; but it would be no surprise if Bush Administration hawks, who have long wanted to step up pressure on Pyongyang, now saw little reason to extend their patience.

"The problem is that once the shuttle is a meter or two off the ground, there is nothing you can do to save it if something goes wrong," says Corin Segal, an aerospace scientist at the University of Florida. NASA sponsors Segal's research into developing a launch system that would allow for horizontal takeoffs. He estimates that technology could be 15, even 20 years away. In the meantime, if NASA wants more giant leaps, it may have to start with a small step...
