...wanted to do something for the wives. So I decided to offer what I had-my houses." Although Marello declares that he will make "absolutely no use" of the astronauts' names, it is unlikely that NASA will allow the girls to accept the generous offer. In the past, the answer has always been: "Thanks, but no thanks...
During the past weeks, TIME has interviewed some of the top men in key branches of ecology. All agree that ecologists combat threats to the environment. They differ only in the kinds of actions they would take...
...first, the data sent back to earth by two Mariner spacecraft more than 60 million miles away seemed to offer as little hope as the lunar rocks that life would be found elsewhere in the solar system. Flying past the planet Mars, the small, instrument-packed spacecraft detected no evidence of nitrogen, an indispensable ingredient of life on earth. Probing the upper reaches of the Martian atmosphere, they failed to find anything like the ozone shield that protects the earth's surface from the sun's deadly rain of ultraviolet radiation. Even their stunning close-up photographs from...
...week's end the infra-red spectrometer on board Mariner 7, the second of the two vehicles that flew past Mars, detected two gases-ammonia and methane-that could indicate the presence of primitive life. Both are produced on earth by biological decay. George C. Pimentel, a University of California chemist, said that he was unable to determine the amount of ammonia in the Martian atmosphere, but he estimated the concentration of methane as "no more than a few parts per million." In the earth's atmosphere, the amount is about 1.5 p.p.m.-and added rather jovially that...
...project would cost perhaps $60 billion, prefer less expensive unmanned probes beyond Mars. Last week 23 space scientists strongly urged "grand tours" of the outer planets in the mid-1970s. At that time, Jupiter, Saturn, Neptune, Uranus and Pluto will be so aligned that a spacecraft could sweep past at least three of them in a single, multibillion-mile journey. This rare planetary configuration, the panel noted, will not occur again for another 179 years...
