contributions to the national space program over the years,and expressed the Caltech community's pride in the scientificachievements of Mariner 10. Dr. William H. Pickering observedthat this project has added another notable chapter to the12-year story of Mariner, which has led the way in exploringthe near planets of the solar system. He also congratulated theawardees, and said that JPL and Caltech are proud of them. Alist of the awardees follows.

Meanwhile, back in space, the Mariner 10 spacecraft is spacecraft internal temperatures as a result. Power to thenow cruising quietly, having completed its primary mission by spacecraft tape recorder started to toggle off when the tapereturning new scientific data during its flight past Venus and recorder was on, and the experimental X-band transmitterMercury in February and March. Its trajectory was altered by suffered some performance degradation. Three weeks later, themaneuvers on May 9, May 10, and July 2, 1974, to bring the spacecraft telemetry subsystem experienced a failure thatspacecraft back to Mercury for a second encounter on resulted in the loss of nearly half of the engineering telemetry.September 21, 1974. Photographic coverage of the planet for Later, the low energy charged particle detectors in the Plasmathis flyby will in part duplicate the regions photographed last Science Experiment began approaching the end of their usefulMarch 29, but will primarily cover the south pole and the life, so this cruise instrument was turned off to conserve thesunlit side of the planet, cartographically tying together the detectors for the encounter periods. Most recently, the tapetwo sides of Mercury observed on the first flyby. There will be recorder began to operate erratically and finally completelyno Earth or Sun occultation on this pass.
