17th International Symposium on Earth Tides, Warsaw, Military University of Technology, 15-19 April 2013
News
Participation of the members of the Department of Planetary Geodesy in the international conference: 17th International Symposium on Earth Tides, Warsaw, Military University of Technology, 15-19 April 2013.

In the middle of April this year several members of the Department of Planetary Geodesy actively participated in the international conference Earth Tides Symposium (ETS), which is a cyclic conference organized every 4 years. The main organizer of the meeting is the Sub-Commission 3.1 of the International Association of Geodesy “Earth Tides and Geodynamics”. Over 70 scientists took part this year in the conference, representing among others France, Germany, Canada, China Nanking, Spain, Austria and USA. It was decided that about 25 papers presented at the meeting will be published in a special issue of the peer reviewed journal “Journal of Geodynamics”.

Participation of the members of the Depatment of Planetary Geodesy in the international conference: European Geosciences Union General Assembly 2013, Vienna, 7-12 April 2013

The conference European Geosciences Union General Assembly (EGU2013) was held in 7-12 April this year. In the conference participated representatives of the Space Research Center PAS, between others several members of the Department of Planetary Geodesy. The conference was divided into 25 panels, one of them was Geodesy. Six sessions were realized in the frame of this panel. In the conference participated more than 11000 participants.

Robotics in SRC PAS - LEMUR
News
Written by Rafał Przybyła   
Space agencies and companies work on the program of sending into the orbit autonomous servicing satellites, which could repair  damaged commercial satellites. In October 2011 Space Mechatronics and Robotics Laboratory started the project "Design and construction of a prototype of the manipulator as a key component of the satellite orbit servicing system" implemented under the LEADER II program of National Centre for Research and Development. LEMUR, the name of the project was chosen by voting of the project team members.

Robotics in CBK PAN – Penetrator HEEP
News

Space Research Centre of the Polish Academy of Sciences (CBK PAN) has been involved in the development of space penetrators since 1997. The Institute has a lot of experience in developing hammering penetrators, including the flight models of MUPUS for ESA Rosetta mission and CHOMIK for the Russian Phobos-Grunt mission.

Currently Space Mechatronics and Robotics Laboratory is developing an entirely new penetrator called HEEP (High Energy and Efficiency Penetrator), which is several times stronger than any previously developed electromagnetic penetrator.

History
1976
- 20 September:the Polish Academy of Sciences Presidium establishes the Space Research Centre

1977
- 1 February: the Space Research Centre officially begins its activity.
The scientific staff is a combination of small research groups from the Institute of Geophysics, the Astronomical Observatory of Warsaw University, the Warsaw University of Technology and the Institute of Mathematical Machines. The Centre  also includes the Astronomical Observatory in Borowiec (now the Astrogeodynamic Observatory) near Poznań and the Wrocław Heliophysics Labolatory of the PAS Institute of Astronomy (now the Solar Physics Division.)

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).

Interstellar neutral atoms of helium from the local interstellar medium are observed by the Interstellar Boundary Explorer (IBEX) spacecraft in the Earth orbit. Researchers from CBK PAN, together with international collaborators, analyze these observations to determine the Sun’s motion with respect to the local interstellar medium and the temperature of this medium. In a broader perspective, results of these analyses provide important insight into mechanisms of interaction of the heliosphere with its surroundings. In a paper recently published in The Astrophysical Journal they analyzed data from two energy channels of the IBEX-Lo detector previously not used, in addition to the data from the channel used beforehand, and obtained a better assessment of these quantities.

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.
