...body is subjected to trauma or injury. As soon as that splinter slices into your finger, for example, specialized sentinel cells prestationed throughout the body alert the immune system to the presence of any bacteria that might have come along for the ride. Some of those cells, called mast cells, release a chemical called histamine that makes nearby capillaries leaky. This allows small amounts of plasma to pour out, slowing down invading bacteria, and prepares the way for other faraway immune defenders to easily enter the fray. Meanwhile, another group of sentinels, called macrophages, begin an immediate counterattack and release...
...business on an equal playing field...At the end of the day, I supported the ban and believe it’s the right public health direction to be going in, but my “is government gong a bit far” antenna was at a full mast during the debate...
Unlike little Sojourner, Spirit and Opportunity are full-blown Mars cars, about the size of golf carts and fairly stuffed with instruments--including a bristle of cameras atop an almost 5-ft. antenna mast that will provide an eye-level view of the terrain, as opposed to the shin-level view Pathfinder provided. Like their predecessor, they will be visiting areas of the planet that scientists believe were once deluged with water, precisely the kind of spots extraterrestrial organisms would, at least in theory, love. If Mars ever harbored life, the 90 or more days Spirit and Opportunity will spend...
What the rovers will see both inside the samples and elsewhere promises to be considerable. In addition to the four cameras perched at the top of the mast, two in front will help the vehicles go where they need to, and two in back will help them steer. Most impressive, a microscopic imager on the robot arm will do close-up work, squinting deep into rocks to study their texture. "This thing's got eyeballs all over the place," says Squyres...
When they go, they will take 6 billion earthlings with them--after a fashion. Each rover carries an array of eight cameras, including one perched atop the mast for a you-are-there view. On the 1997 mission, the rover's camera was barely 10 in. off the ground. "It was like crawling around on your belly," says project scientist Joy Crisp of NASA's Jet Propulsion Laboratory...
