"It's a 'great Scott'-sized rock," said the delighted Duke, recalling the record 22-Ib. specimen picked up by Apollo 15 Astronaut David Scott last year...
Many of the scientific benefits from Apollo 16 are still in the offing. With a new, semiautomatic $2,000,000 electronic camera, developed by the Naval...
...help protect their health during their extraterrestrial explorations, U.S. astronauts routinely go on special diets prior to launch. The Apollo 16 crew that landed on the moon last week has been on an even more highly specialized diet than usual. For three days before blastoff, the trio ate foods laced with potassium, and even the eggs in their farewell omelets came from hens raised on high-potassium feeds. Their in-flight food was similarly seasoned. The astronauts are not complaining; Ken Mattingly told Mission Control that the potassium even added a certain zest to his tomato soup...
...reason for the astronauts' unusual diet is cautionary rather than culinary. Two members of Apollo 15's crew went through brief periods of heartbeat irregularities, and NASA doctors suspected the reason. The two men who suffered the problem had lost 15% of their normal potassium. They were also the ones who landed and worked on the moon. Potassium, a body salt that affects the electrical conductivity of the heart, is essential to controlling cardiac rhythm...
NASA's director of life sciences, Dr. Charles Berry, is unable to explain why the potassium-loss problem, which had not bothered members of earlier missions, surfaced during the last Apollo flight. But the astronauts' physician was determined not to let it become a hazard for Apollo 16. In addition to replenishing the crew's lost potassium through diet, Berry has safeguarded the spacemen by setting up an emergency cardiology service to monitor their heartbeats and transmit their electrocardiograms by telephone to two heart specialists. He has also supplied the astronauts with drugs to be used...
