James M. Anderson, a teaching fellow in biology said yesterday the new policy will have a mixed impact on atmospheric research, his specialty. Funds for experiments investigating the Earth's atmosphere would probably be boosted, he said, while some programs designed to study the atmospheres of other planets, particularly Venus, Mars and Jupiter, are now in "greater jeopardy...
...well after sunset. Some blue remains in the darkened Western sky. Jessie can see only the lights of his combines, as one by one they disappear over a hill. "Follow that star," drawls Jessie over the radio. The combines, like tanks on night maneuvers, head west, following Venus, which is low and bright in the sky. "We've got it!" Gary Coleman, driver of the lead combine yells back. He slows his machine, turns and lowers the cutting head into a rich wave of uncut field...
...billion years and will remain relatively unchanged for another 5 billion. After the star exhausts most of the hydrogen near its core and begins to burn hydrogen in its outer regions, it swells into a red giant. When the sun reaches this stage, its hot gases will envelop Mercury, Venus and the earth...
...Pioneer Venus 1 will travel more than halfway around the sun, flying outside Earth's orbit for the first three months, then crossing inside Earth's orbit for the last four months of a circuitous, 480 million-km (300 million mile) journey to Venus. This flight path will lessen the accelerating effect on Pioneer of the sun's gravity. As a result, the ship will make its approach to the planet at a lower speed than if it had taken a more direct route across space. Thus a smaller retrorocket will be needed to slow Pioneer down...
Pioneer 2's mission is considerably different. Scheduled for launching on Aug. 7, the probe will take a more direct route-only 354 million km (220 million miles) long-and will arrive at Venus only five days after Pioneer 1. While it is still several million miles away from Venus, the Pioneer 2 bus will release a large probe and then three small ones. The bus and separated probes will continue their journey until they plunge into the Venusian atmosphere. Packed with instruments, they will all begin to take readings of atmospheric temperatures, density, composition and distribution as they...
