World Science report [tech.]: according to foreign media reports, the European Space Agency is about to launch European Earth's gravity field and ocean circulation exploration satellite (Goce), the satellite can be on the Earth's gravity field every minute for three-dimensional measurement of change. Scientists will use the collected data to better understand the oceans campaign, design Earth Highlands measurement system.

Smooth shape special appearances

The ultimate "build" satellite will build a reformed ICBMs from Russia the Plesetsk launch site. "Zipped" (ROCKOT) rocket will be GMT 16 October 14 21 pm launched. Launch a satellite into space looks like an ugly box, but the European Space Agency's Earth's gravity field and ocean circulation exploration satellite shapes vary. Germany Munich's Lunn · la Mel participated in this task, he said: "this is by far the most beautiful manufactured on a satellite. "Called satellite" supermodel ".

European Earth's gravity field and ocean circulation exploration satellite system into a very nice and smooth appearance, was designed to meet the extreme test environment running. The spacecraft in less than 270 km-altitude residual air flight, arrow and wing nut is very important to keep balance. Most of the Earth observation mission, this track is a bit low, but on the European Earth's gravity field and ocean circulation exploration satellite, to feel the Earth surrounding the very subtle gravity anomalies, it must stay at such a height.

The European Space Agency's Earth's gravity field and ocean circulation exploration satellite project manager Danilo · the wood it is explained that: "at present we are understanding of Earth's gravity field is not perfect. Gravity is our daily life indispensable a force, with it, we can double foot stations on the ground. Most people believe that the Earth's gravity everywhere is the same, but this is not the case. We in the Arctic than at the equator of the heavier weight. "Earth's shape is the cause of this exception. This is because the Earth is not a perfect sphere, relatively speaking, the more flat earth poles. The inner layer of the Earth is not a homogeneous composition of rock, and some regions more thick crust, or density.
