Toulouse scientists and aerospace engineers want to discuss it at the weekend when the lander of ESA’s space probe “Rosetta” on the comet “67P / Churyumov-Gerasimenko” to land. There was wanted a shortlist of up to five locations, can be found in the organic material, among other things, said Hermann Böhnhardt from the Max-Planck-Institute for Solar System Research in Göttingen, the news agency dpa.
The 59-year-old researcher is involved as a Senior Fellow of the land issue in the discussions in Toulouse. “In addition, should go on and below the landing area the sun, which is not the case everywhere. We want to measure how the surface of the comet during the day and night behavior, “he explained.
The landing mid-November to the first on a comet in the history of space travel is. The probe is traveling in space since 2004, will explore one of the most pristine celestial bodies, the European Space Agency ESA – Comets are remnants of the early days of the solar system. Notes on the origin of life The researchers hope that in the form of certain protein building blocks
The need for planning the landing surface images of the comet provided the developed in Göttingen camera system “Osiris”. Models were calculated from his pictures where larger boulders are visible. “Other instruments show us where certain gases and dust emanating from the comet. We want to arrive at a point where we can measure such cometary activity, “says Böhnhardt. On October 12, the landing area shall stand.
But before making the lander “Philae” to work, it must first land safely on “Tschuri”. The German Aerospace Center (DLR) said in a press release that the landing could take place around the target location within a radius of 500 meters. “Exact we can not calculate the landing site,” explains DLR scientists Stephan Ulamec. “Philae” must namely autonomously land on the comet’s surface. A control of the Earth is not possible due to the large distance: The radio signal would be 30 minutes traveling
