Using special sensors that can "sniff" the chemical signature of a gas, technicians traced the leak to a ¾-in.-long crack in the hot-gas manifold, where hydrogen and oxygen are gathered under high pressure (4,400 Ibs. per sq. in.) before combustion. Undiscovered, the leak might have caused an explosion. This week technicians hope to install a new engine, trucked from the National Space Technology Laboratories in Bay St. Louis, Miss...
...moral. Despite quakes and eruptions, the earth is agonizingly incremental, and McPhee must use all his skills to extract its story. On the reluctant process of diamond formation: "They want to be graphite, and with a relatively modest boost of heat graphite is what they would become, if atmospheric oxygen did not incinerate them first. They are, in this sense, unstable-these finger-flashing symbols of the eternity of vows, yearning to become fresh pencil lead." Noting that the last Ice Age stopped around Ebbets Field, vanished home of the Brooklyn Dodgers, he writes: "When a long-ball hitter...
DIED. George Bond, 67, chief scientific investigator and senior medical officer for the Navy's Sealab missions, which tested human capacity to live and work undersea; of heart disease; in Charlotte, N.C. Bond developed a process of saturating body tissues with a mix of helium and oxygen to withstand pressure. In the first two Sealab missions (1964-65), aquanauts spent nine days or more in a 57-ft.-long steel cylinder some 200 ft. below the ocean's surface. Observing from above, "Papa Topside" found that the men could function but became susceptible to the "breakaway phenomenon," suffering...
...earnest Apollo 13 astronaut, who was due to be sworn in this week as a Republican Congressman from Colorado; of lung and bone-marrow cancer; in Washington, D.C. Chosen as a replacement one day before unlucky 13's launching in 1970, the civilian astronaut coolly announced, when an oxygen tank exploded, "Houston, we've got a problem," then initiated emergency procedures he had helped develop. Turning to politics, he spent most of his life savings in an unsuccessful bid for a senatorial nomination in 1978, but came back last year to win 77% of the votes...
...Johns Hopkins University in Baltimore, is based on experiments on baboons. It has been used in only a handful of human patients suffering from severe thalassemia or sickle cell anemia. These blood disorders result from defects in the genes that control production of hemoglobin, the substance that carries oxygen in the blood. In essence, thalassemia victims cannot form healthy red blood cells on their own and require periodic transfusions; sickle cell patients are subjected to painful blood vessel blockages...
