...NASA STICK WITH THE SPACE SHUTTLE SO LONG? Though the space shuttle is viewed as futuristic, its design is three decades old. The shuttle's main engines, first tested in the late 1970s, use hundreds more moving parts than do new rocket-motor designs. The fragile heat-dissipating tiles were designed before breakthroughs in materials science. Until recently, the flight-deck computers on the space shuttle used old 8086 chips from the early 1980s, the sort of pre-Pentium electronics no self-respecting teenager would dream of using for a video game...
...decades of use, shuttles have experienced an array of problems--engine malfunctions, damage to the heat-shielding tiles--that have nearly produced other disasters. Seeing this, some analysts proposed that the shuttle be phased out, that cargo launches be carried aboard by far cheaper, unmanned, throwaway rockets and that NASA build a small "space plane" solely for people, to be used on those occasions when men and women are truly needed in space...
...That's why NASA must be America's most optimistic government agency, that it can keep muscling forward in the face of such odds. Columbia was the 88th mission since the Challenger was lost in January 1986--one flight lost to the cold, one perhaps to the heat...
...Hispanic immigrants spread beyond their strongholds in New York, California and Texas, summer sports--and the spectators that cluster around them--are turning up the heat on already simmering ethnic and class tensions, according to Princeton University sociologist Douglas Massey. "There are complaints in parks and fields all across America. Volleyball just happens to be the local version in Danbury," he says. "But if you know anything about Latin cultures, this is pretty innocent stuff. They bring their families. The men aren't getting totally drunk because, really, they are there for the sports...
...Unfortunately, in the Pacific we're really pushing the boundaries of how well the dna is preserved," says Matisoo-Smith, who will soon send her results to a U.S. lab for replication. Hands dusty from gently loosening fragile bones with a dental pick, Hallie Buckley works in the Efate heat barefooted and in a T shirt. A biological anthropologist at New Zealand's University of Otago, Buckley specializes in prehistoric health, and the discovery of Teouma seems to her a small miracle: "It just keeps getting better." Hidden within these graves, she hopes, are clues about how the first humans...
