Astronomical institute as cr

Colaboration with European Space Agency (ESA)


Solar and Heliospheric Observatory

Start 1995. SOHO continuously watch the solar photosphere, corona and solar wind. SOHO is equipped with 12 instruments. SOHO is the most successful solar satellite of all times. It discovered also over 1500 comets.

Astronomical Institute AS CR

  • Czech participation:

    • Utilization of the extensive archive of SOHO data and analysis of spectra andspectral images of selected events.

    • Proposing, organization and making new observations, especially with CDS and SUMER instruments.

    • Continuation in the development of modern analytical methods based on theoretical approach to plasma spectroscopy in non-equilibrium stages and solar MHD.

    • Utilization of the results received for the preparation of the next solar project of ESA - Solar Orbiter.

XMM - Newton

X-ray Multi-Mirror Mission – Newton

Start 1999. The satellite observe the universe in x-rays, which cannot be seen from the Earth. This x-rays come from accretion of the matter around black holes, supernovae, dark matter, gamma-ray bursts, active galactic nuclei.

Astronomical Institute AS CR

  • Czech participation:

    • We propose to analyze and interpret X-ray spectra of accreting black holes in active galactic nuclei (AGN) and Galactic black holes, including the publicly available observations and those in which we are currently involved

    • in collaboration.

    • Our main objective is to develop and enhance computational tools that will be primarily dedicated to the analysis and interpretation, relying

    • on unprecedented combination of collecting area and the energy resolution of the ESA cornerstone XMM-Newton mission.

Colaboration with European Space Agency (ESA)


International Gamma-Ray Astrophysics Laboratory

Start 2002. The satellite observe high energy sources like black holes, gamma-ray bursts, active galactic nuclei. Integral is equipped with two x-ray telescopes, optical and gamma detector.

Astronomical Institute AS CR

  • Czech participation:

    • Czech participation in the project is represented by a coordination of activities in the Czech Republic, scientific data analysis and by organization

    • of a Data Center in Astronomical Institute in Ondrejov. A few team members

    • are (were) directly participating in the main Data Center (ISDC) in Switzerland.

Colaboration with European Space Agency (ESA)


Gravity field and Steady-state Ocean Circulation Explorer

Start 2009. GOCE orbiting the Earth systematically and measure the gravitational potential. This provides to study the Earth interior and construct new model of the shape of the Earth.

Astronomical Institute AS CR

  • Czech participation:

  • Our small group from the Czech Republic around the Astronomical Institute

  • of the Czech Academy of Sciences wants to focus on the following topics, with possible extension due to course:

    • Orbit choice and tuning for GOCE measuring phases.

    • Novel geodetic computational methodologies.

    • Comparison of detailed satellite and terrestrial data.

    • Detection of hidden impact (meteoritic) structures on the Earth surface.

Colaboration with European Space Agency (ESA)


PRoject for OnBoard Autonomy

Start 2009. The PROBA satellites are among

the smallest ever to be flownby ESA, but they are making a big impact in space technology. PROBA-2 has two instruments to observe the sun and three to measure plasma.

Astronomical Institute AS CR

  • Czech participation:

    • Dual Segmented Langmuir Probes (DSLP), which will measure electron density and temperature in the background plasma of the Earth’s magnetosphere.

    • The main goal of the DSLP instrument is to test the new type of the basic plasma parameters measurements as well as functioning of the instrument in the space environment.

Astronomical institute as cr5

Colaboration with European Space Agency (ESA)


Start 2012. The main purpose of the satellite is to measure stars. Gaia will measure positions, proper motions, brightness and spectrum

of the stars with unprecedented accuracy. Unique catalogue consists

of 1 billion stars and 3D model of the solar neighborhood

is expected.

Astronomical Institute AS CR

  • Czech participation:

    • Ground-based observation in Gaia pre and post-launch time.

    • Reduction of reference star spectra.

    • Gaia CU7 sub-workpackage on Eruptive stars with emphasis on Be stars.

    • Gaia Software development.

    • Gaia CU7 sub-workpackage on Cataclysmic Variables.

    • Gaia CU7 sub-workpackage on Optical Counterparts of High-Energy Sources.

    • Special Variability Detection and Variability Characterization.

    • Simultaneous observations by robotic telescopes.

Colaboration with European Space Agency (ESA)


PRoject for OnBoard Autonomy

Start 2012. Proba-3 will demonstrate the technologies required for formation flying of multiple spacecraft. An instrument to observe the solar corona will complement the demonstration.

Astronomical Institute AS CR

  • Czech participation:

  • ASPIICS – Coronograph with the external occulter.

    • ASPIICS will address the question of coronal heating and of the role of waves by characterizing propagating fluctuations in the solar wind acceleration region and by looking for oscillations in the intensity and Doppler shift of spectral lines.

    • The combined imaging and spectral diagnostics capabilities available with ASPIICS will allow to map the velocity field of the corona both in the sky plane and along the line-of-sight by measuring the Doppler shifts of emission lines.

Astronomical institute as cr7

Colaboration with European Space Agency (ESA)


Start 2014. The probe is planned to fly to the Mercury, which is only a little explored planet. BepiColombo will consist of two modules, one for magnetic field research and the second for surfaceanalysis.

Astronomical Institute AS CR

  • Czech participation:

    • Solar wind

    • Structure and configuration of Mercury's magnetosphere

    • How, when and where does the solar wind impact the planet?

    • What are the mechanisms for charged particle acceleration in the Hermean magnetosphere?

    • Do substorms occur at Mercury and how do they differ from substorms at Earth?

    • Data distribution system
