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.

NASA selects mission to study the boundary of the heliosphere: CBK PAN is a part of the winning team! Print E-mail
Wednesday, 06 June 2018 15:36

CBK PAN will participate in a NASA space mission Interstellar Mapping and Acceleration Probe (IMAP), scheduled for launch in 2024. The selection of the winning proposal submitted in response to the Announcement of Opportunity released in 2017, was announced in Washington DC on June 1, 2018 (https://www.nasa.gov/press-release/nasa-selects-mission-to-study-solar-wind-boundary-of-outer-solar-system).

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.

Evolution of the solar Lyman-alpha profile line Print E-mail

Lyman-alpha line is one of the most prominent features in the UV part of the solar spectrum. It allows us to estimate the magnitude of radiation pressure, which is a force that photons from the Sun exert on hydrogen atoms. Radiation pressure is, next to the gravitational force, the main factor that determines the trajectories of neutral hydrogen and deuterium atoms inside the heliosphere.
