Comet chaser Rosetta's Earth swingby right on schedule.Byline: ANI Paris, November 7 (ANI): Estimates have shown that European Space Agency's (ESA 1. (architecture) ESA - Enterprise Systems Architecture. 2. (body) ESA - European Space Agency. ) comet chaser Rosetta's Earth swingby is right on schedule, and it would pass within a few kilometers of the planned point of closest approach during the swingby. After the trajectory correction maneuver on October 22, Rosetta has lined up on a near-perfect Earth approach path. The maneuver was so precise that flight dynamics and mission control experts have decided not to use the additional maneuver slot. Rosetta's orbit has been determined using radiometric data received from ESA and NASA NASA: see National Aeronautics and Space Administration. NASA in full National Aeronautics and Space Administration Independent U.S. ground stations, and estimates now show that she will pass within a few kilometers of the planned point of closest approach during next week's Earth swingby. If necessary, additional maneuver slots are available at 24 and 6 hours prior to closest approach. Rosetta is now forecast to pass over a watery point just south of the island of Java at an altitude of 2481 km at 13.34 km/s relative to Earth. This estimate will be updated in the coming days. Though time will be short, several science observations are planned around the swingby to exploit Rosetta's unique perspective and powerful instrument suite. The planned observations include imaging with the scientific camera system OSIRIS Osiris (ōsī`rĭs), in Egyptian religion, legendary ruler of predynastic Egypt and god of the underworld. He was the son of the sky goddess Nut and the earth god Geb. , an attempt to look for water on the Moon with MIRO, study of the magnetosphere magnetosphere: see Van Allen radiation belts. magnetosphere Region around a planet (such as Earth) or a natural satellite that possesses a magnetic field (see with the suite of Rosetta plasma instruments, and observations of Earth's atmosphere “Air” redirects here.

The instruments will be turned on one-by one beginning tonight and will stay on through the swingby. The goal of the swingby is to assist Rosetta to reach the comet for its prime mission. Accordingly, spacecraft operations will have priority over the science activities on November 13. During the two nights before closest approach and one night afterwards, members of the Rosetta team will conduct observations from ESA's Optical Ground Station in Tenerife, Spain. They will also carry out an experiment to investigate whether a laser beam can be detected by OSIRIS.ANI) Copyright 2009 Asian News International The Asian News International (ANI) agency provides multimedia news to China and 50 bureaus in India.
