Vandenberg Air Force Base.....U.S., space vehicle launch facility. Contains the Western Test Range (WTR), is located near Lompoc, California. Location 24.7o N, 120.6o W. Also known as the Western Space Missile Center (WSMC) It has been the site of many military missile launches, of NASA launches of satellites intended to go into high inclination or polar orbits. Vandenberg cannot launch satellites toward the east because first stages would fall in populated areas. Launch and landing facilities that enable polar orbits for the space shuttle were built then deactivated following the Challenger accident in 1986. They will be reactivated sometime in the 1990's.

VIKING.....U.S. NASA, satellites, scientific. Obits Mars and sent landing vehicles to the surface. VIKING 1 went into Martian orbit on June 19, 1976, and the lander set down on the western slopes of Chryse Planitia on July 20, 1976. It soon began its programmed search for Martian micro-organisms (there is still debate as to whether the probes found life there or not), and sent back incredible color panoramas of its surroundings. One thing scientists learned was that Mars' sky was pinkish in color, not dark blue as they originally thought (the sky is pink due to sunlight reflecting off the reddish dust particles in the thin atmosphere). The lander set down among a field of red sand and boulders stretching out as far as its cameras could image. The VIKING 1 orbiter kept functioning until August 7, 1980, when it ran out of attitude-control propellant. The lander was switched into a weather-reporting mode, where it had been hoped it would keep functioning through 1994; but after November 13, 1982, an errant command had been sent to the lander accidentally telling it to shut down until further orders. Communication was never regained again, despite the engineers' efforts through May of 1983. An interesting side note: VIKING 1's lander has been designated the Thomas A. Mutch Memorial Station in honor of the late leader of the lander imaging team. The National Air and Space Museum in Washington, DC is entrusted with the safekeeping of the Mutch Station Plaque until it can be attached to the lander by a manned expedition. VIKING 2 was launched on September 9, 1975, and arrived in Martian orbit on August 7, 1976. The lander touched down on September 3, 1976 in Utopia Planitia. It accomplished essentially the same tasks as its sister lander, with the exception that its seismometer worked, recording one marsquake. The orbiter had a series of attitude-control gas leaks in 1978, which prompted it being shut down that July. The lander was shut down on April 12, 1980. The orbits of both VIKING orbiters should decay around 2025.

VOYAGER 2 took advantage of a rare once-every-189-years alignment to slingshot its way from outer planet to outer planet. VOYAGER 1 could, in principle, have headed towards Pluto, but JPL opted for the sure thing of a Titan close up.
The two probes, greatly increased our knowledge of the 4 giant planets, their satellites, and their rings. VOYAGER 1&2 discovered that Jupiter has complicated atmospheric dynamics, lightning and aurora. Three new satellites were discovered. Two of the major surprises were that Jupiter has rings and that Io has active sulfurous volcanoes, with major effects on the Jovian magnetosphere. When the two probes reached Saturn, they discovered over 1000 ringlets and 7 satellites, including the predicted shepherd satellites that keep the rings stable. VOYAGER 2, thanks to heroic engineering and programming efforts, continued the mission to Uranus and Neptune. Uranus itself was highly monochromatic in appearance. One oddity was that its magnetic axis was found to be highly skewed from the already completely skewed rotational axis, giving Uranus a peculiar magnetosphere. Icy channels were found on Ariel, and Miranda was a bizarre patchwork of different terrains. 10 satellites and one more ring were discovered.
In contrast to Uranus, Neptune was found to have rather active weather, including numerous cloud features. The ring arcs turned out to be bright patches on one ring. Two other rings, and 6 other satellites, were discovered. Neptune's magnetic axis was Also skewed. Triton had a cantaloupe appearance and geysers. The two VOYAGERS are expected to last for about two more decades. Their on-target journeying gives negative evidence about possible planets beyond Pluto. Their next major scientific discovery should be the location of the heliopause. Low-frequency radio emissions believed to originate at the heliopause have been detected by both VOYAGERS.
