News 24 / .- The European Space Agency (ESA) announces tomorrow the point to what will be the first landing of a comet in history, and will star in his next Rosetta November.
In fact Philae will be a module of a hundred kilos of Rosetta, which should probably settle on 11 November-surface Churyumov-Gerasimenko comet, the spacecraft has been watching close since Aug. 6, from when it is located less than 100 kilometers.
On 25th ESA announced the five possible points of making contact with the floor of the comet, which have been under investigated in detail for three weeks to identify operational and orbital strategies that involve each.
Rosetta has been traveling through space since it was launched in 2004 to make it ten years Rosetta has come to approximate 50 miles away, which allowed its experts “gather more detailed information on each site,” particularly in high-definition photographs of surface temperature measurements of the comet, as well as the pressure and density of gas surrounding its core.
images have been achieved in the structures that can be seen up to ten inches.
In parallel, we have determined the orientation of the comet from the Sun , its rotational speed, mass and surface gravity, other factors are also relevant to assess the technical feasibility of each of the options.
All of them respond to a number of conditions, special offer at least six hours of sunlight during each rotation of the comet, and appropriate lighting conditions for scientific observations and to recharge the batteries of the lander but without overheating occurs.
The ESA must disclose am a first point of landing, but also a second option, the challenges posed by the operation, but also the scientific results that can be expected.
Researchers have focused on comets whom they consider “time capsules” has already warned that the landing maneuver is presumed “complicated” and that will continue for several hours due to the low gravity and mass of the comet.
Once you have landed and fixed to the ground, is expected to Philae may provide valuable information to scientists for about four months. The orbiter will continue to monitor the evolution of cometary activity until the end of 2015.
Rosetta has been traveling through space since it was launched in 2004 and in that time has traveled almost 6,400 million kilometers in ten years his odyssey to seek answers about the origin of the solar system.
Researchers have focused on comets whom they consider “time capsules” because they were formed at the origin of the solar system makes a 4,500 million years ago but since then have fallen away from the star. Consider more deeply know can provide answers about how things were in the beginning.
