NASA announced that Voyager 1, launched Sept. 5, had overtaken its sister ship Voyager 2, launched Aug. 20, about 77.5 million miles from earth on its way to encounters with Jupiter and Saturn. Voyager 1 would arrive at Jupiter in 1979 in the lead by 4mo, and at Saturn in 1980 ahead by 9mo. If all went well by the time Voyager 2 reached Saturn in Aug. 1981, NASA might send it on toward. Uranus where it should arrive by Jan. 1986. Both spacecraft would eventually escape earth's solar system. (NASA Release 77-252)
JSC reported it had modified its mission control center to use solar power for dehumidifying the building. Solar panels installed on the roof would provide heat 60% of the time, according to weather calculations for the Houston area, and would save about 1.5 million ft of natural gas per yr at a construction cost of about $240 000. The modification was part of a joint NASA/DOE solar-energy demonstration project. (JSC Release 77-86)
