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...
...went wrong with Lenoir's suit. Despite all efforts during the flight, the suit would not reach the required pressure, 4.3 Ibs. per sq. in. (Although this is only a third of the earth's normal atmospheric pressure, it is adequate because the astronauts are breathing pure oxygen rather than the oxygen-nitrogen mix that they would get at sea level...
...panel's most distressing discovery was a stray steel chip, perhaps a burr from a screw, in an exhaust vent of the suit's oxygen supply system. If the fragment had been in the pure oxygen area and caused a spark (by hitting a wall, for example), it might have touched off a catastrophic flash fire, killing Lenoir and possibly ripping a fatal hole in Columbia's sides as well. In fact, a suit did catch fire in a test at Houston two years ago; fortunately no one was wearing it. It was so incinerated that...
...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...
