Rosetta papers with CBK PAN participation
Our research

The issue of Science magazine, 23 January 2015, features four papers about the investigations made with the Rosetta OSIRIS scientific cameras and VIRTIS instruments. Three are co-authored by CBK PAN researcher, prof. Hans Rickman, who is a lead scientist within the OSIRIS team. The fourth paper refers to the results obtained in the experiment VIRTIS, in which dr. Maria I. Błęcka participates.

The Solar Physics Division of the Space Research Centre won PAS-NASU competition!
News

The research work: “Dynamic structure of energetic particles in the near Earth space” won special competition organized by the President of the Polish Academy of Sciences (PAS) and President of the National Academy of Sciences of Ukraine (NASU). This research was performed using meas-urements from Polish X-ray spectrophotometer SphinX and the Ukrainian Satellite Telescope of Electrons and Protons STEP-F. Both SphinX, and STEP-F instruments were operating onboard CORONAS - PHOTON satellite. Awarded also were joint works on development of further scientific experiment for interplanetary spacecraft “Interhelioprobe".

Rosetta: Rendezvous with the comet
News

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: Scrutinizing the nucleus
News

The Rosetta spacecraft continues to move in close vicinity of the nucleus of comet 67P/Churyumov-Gerasimenko, and it has reached distances less than 10 kilometers from the surface. Images have been taken with an amazing resolution. Even so, it is not immediately clear what it is that we are seeing. This discussion is ongoing and will certainly continue for some time. Actually, even the large-scale features are sometimes hard to interpret, and this makes it difficult to reach conclusions about the most fundamental questions about the origin of the nucleus.

The smallest dust grains in the circumsolar dust cloud are the nanodust particles, i.e., the dust grains with the sizes of a few to a few tens millionth parts of millimeter. They are so small they include just several dozen thousands of atoms.

Interplanetary space is filled with magnetized plasma from the Sun (the solar wind) and interstellar gas, mainly hydrogen and helium, which continuously flows through the heliosphere. The interstellar atoms are ionized by extreme ultraviolet radiation and the solar wind. In result of ionization of the interstellar atoms, new ions in the solar wind are created.

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.

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).
