The heliosphere is not round! PDF Print E-mail

The heliosphere is a region in the interstellar space filled with the solar wind plasma, emitted by the Sun. Since the Sun is traversing a partly ionized, magnetized cloud of interstellar gas, the solar wind expansion must be eventually arrested at a certain distance to the Sun. This happens in the locations where the solar wind pressure becomes equal to the pressure of the interstellar matter. Ultimately, however, the solar wind matter cannot accumulate infinitely inside the heliosphere and must find an exit path to the interstellar space. But where exactly is this path located? And is there just one evacuation path or more? These questions cannot be answered directly because up to now there have been just two active space probes – Voyager 1 and 2 – to reach the boundary regions of the heliosphere, and this happened in the regions least suspect of being anywhere close to the solar wind evacuation path. Therefore, answering these question can only be done by remote-sensing measurements and theoretical modeling.

Rosetta: Rendezvous with the comet Print E-mail
Thursday, 25 September 2014 15:19

The Rosetta spacecraft has now been moving in an orbit around the nucleus of its target comet, 67P/Churyumov-Gerasimenko, since several weeks. The orbit is very close – just a few tens of kilometers away – and different from the perfect ellipse that would result, if the target were regular and spherical. By contrast, the early pictures already showed that the overall shape of the nucleus is quite weird, and hence, Rosetta has to travel in a complex, distorted gravity field. But in spite of such difficulties, everything goes as planned, and as we shall now describe, the touchdown site for the Philae lander has been identified.

Rosetta: Closing in on the comet Print E-mail
Tuesday, 19 August 2014 12:35

The Rosetta spacecraft is now in the immediate vicinity of the comet nucleus to be explored, the one of Comet 67P/Churyumov-Gerasimenko. This target will soon be mapped systematically, in great detail, as part of the preparations for the touchdown of the Philae lander, foreseen for November this year. However, the OSIRIS cameras have already delivered quite astounding pictures of the weird object, and we are as yet far from understanding exactly what we are looking at. Here are some examples of the riddles that have been posed and the scientists of the camera team are working on.
