CONSERT
CONSERT (COmet Nucleus Sounding Experiment by Radiowave Transmission) is a scientific experiment on board the European Space Agency's Rosetta mission, launched in 2004, to provide information about the deep interior of the comet 67P/Churyumov-Gerasimenko upon the probe's rendezvous with the comet in 2014. The CONSERT radar was to perform tomography of the nucleus by measuring electromagnetic wave propagation from the Philae lander and the Rosetta orbiter throughout the comet nucleus in order to determine its internal structures and to deduce information on its composition. The related lander and orbiter electronics were provided by France and both antennas were constructed in Germany. The experiment was designed and built in France by Laboratoire de Planétologie de Grenoble (LPG now IPAG) and by Service d'Aéronomie in Paris (SA now LATMOS), in Germany by the Max Planck Institute for Solar System Research (MPS) in Göttingen. The Principal Investigator of CONSERT is Dr. Wlodek K ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Philae Lander
''Philae'' ( or ) was a robotic European Space Agency lander that accompanied the ''Rosetta'' spacecraft until it separated to land on comet 67P/Churyumov–Gerasimenko, ten years and eight months after departing Earth. On 12 November 2014, ''Philae'' touched down on the comet, but it bounced when its anchoring harpoons failed to deploy and a thruster designed to hold the probe to the surface did not fire. After bouncing off the surface twice, ''Philae'' achieved the first-ever "soft" (nondestructive) landing on a comet nucleus, although the lander's final, uncontrolled touchdown left it in a non-optimal location and orientation. Despite the landing problems, the probe's instruments obtained the first images from a comet's surface. Several of the instruments on ''Philae'' made the first in-situ analysis of a comet nucleus, sending back data regarding the composition of the surface and outgassing from the subsurface. In October 2020, scientific journal ''Nature'' published a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
