The dawn detector will be elevated to a higher orbit (video) www.q1se.com


The Dawn spacecraft will be upgraded to a higher orbit since dawn to enter into a higher orbit using Ceres, the amount of remaining hydrazine will decline, because it does not consume a lot of fuel to overcome the gravitational effects of ceres. Tencent space news according to foreign media reports, the Ceres in low orbit were observed for more than eight months after the NASA, the "dawn" spacecraft will be upgraded to a higher orbit, with a new perspective of observing the dwarf planet. At present, the dawn returned a large number of pictures and data in Ceres on the surface of 385 kilometers, the distance than the international space station on earth closer to many. Now, the research team is considering to adjust the detector to a higher orbit, to study new scientific problems. Dawn has completed its main task in June 30th this year, the research of Vesta and Ceres are far beyond the initial expectations, NASA decided to extend the mandate of the dawn, launched a new scientific research on ceres. Among them, limit the dawn operation cycle is a very important factor is the total amount of hydrazine, which is a kind of adjusting detector observation angle and communication with earth for propellant. Now, since the dawn of Ceres to enter into a higher orbit, using the amount of remaining hydrazine will decline because it does not consume a lot of fuel to overcome the gravitational effects of ceres. NASA’s Jet Propulsion Laboratory (JPL) of the chief engineer and director Marc Rayman said the task, most of the detectors can not so easily change the orbit, however, thanks to the dawn, the one and only the ion propulsion system, we can manipulate the best detector data. In September 2nd, dawn will rise to the height of about 1460 kilometers, than last year the dawn that the position of the more recent, but the orbit in different directions, precisely between Ceres and the angle of the sun is different, therefore, the probe will be from a new perspective to observe the ceres. The team is continuing to study the route of the delay and will submit a full plan to NASA next month. (logic compiler) to explore Ceres @ subtitle group grapefruit wood相关的主题文章:
