7 DEVICES THAT ROSETTA WILL EXPLORE THE SURFACE OF THE COMET CHURYUMOV-GERASIMENKO
Last week, the European Space Agency (ESA) announced the final release date – November 11 – probe Rosetta lander Philae, which will land on the surface of the comet 67P / Churyumov-Gerasimenko . On-board module that looks like a spider, there are all the necessary research tools. Read more about them, you will learn in our new article.
Instruments and apparatus which carries Philae, are crucial for the success of the study of the comet 67P / Churyumov-Gerasimenko. This is the first chance to explore this place, and everything should work as one harmonious mechanism. As the resource Universe Today, Philae weighs only 100 kg, so it is a mobile laboratory should be as compact and light.
Philae – light and its energy resources are limited. Therefore, the machine was equipped with a set of photovoltaic panels.
Instrumentation Philae includes sensors to measure quantities such as the dielectric constant. The module will send a comet sound waves, and then examine the characteristics of the reflected signal. Philae will also record sounds from the surface of the comet.
Transmitter to study the comet’s nucleus
ESA interested in the composition and internal structure of the comet. Rosetta and Philae will conduct imaging of the object.
One of the most interesting tools Philae is a mechanical arm with a jackhammer. At the tip of the hammer embedded accelerometer and thermometer to determine the penetration depth and the temperature inside the object. Other sensors will measure the temperature of the comet as it approaches the sun.
Mission Rosetta and Philae – try the taste of a comet, or, in other words, an analysis of its dust and ice. With the help of a drill Philae collect soil samples and send them to its own laboratory for further study of other devices. According to the ESA, this drill uses a hundred times less energy compared to a conventional household drill. On the pictures below the arrow shows its location on the module.
The system, called CIVA-P weighing less than 100 grams will do the color and infrared images of the landing Philae, and the system ROLIS – shoot the process of planting and photographing the comet’s surface close up.
The device will measure the chemical composition of the soil samples of the comet 67P / Churyumov-Gerasimenko. The samples will be affected by radiation, and also to determine the content of hydrogen and helium.
It should be noted that this is not the only research tools on board Philae, but, according to Gizmodo, the most important. By the way, the activities of the module can be monitored to Twitter. Here a link to his account on the social network.Viewing:-94
