INA – An interactive software tool for the statistical analysis of time series with application to space plasma turbulence

The diagram of INA and the schematic illustration of its main functionalities.

INA (Integrated Nonlinear Analysis) is an interactive software product designed to analyze satellite data with advanced nonlinear methods adapted to space plasma turbulence research. The software is developed in the framework of the European Community’s Seventh Framework Programme project STORM (Solar system plasma Turbulence: Observations, inteRmittency and Multifractals) where ISS had a significant contribution. The main developers are Dr. Costel Munteanu (scientist at the Institute of Space Science – ISS), Dr. Marius Echim (senior scientist at ISS and also at the Belgian Institute for Space Aeronomy (BISA), Brussels) and Dr. Peter Kovacs (senior scientist at the Geological and Geophysical Institute of Hungary, Budapest).

INA is publicly available from the website of the project ( as an executable file to be run under Windows or Linux operating systems. The download page is available after registration by email to

The software is written in MATLAB (version 2015a), but it can also be used independently by installing a MATLAB compiler, which can be downloaded freely from here. Through an intuitive graphical user interface (GUI), INA provides a complete statistical analysis of a time series and provides various methods: descriptive analysis, power spectral density (PSD), spectrogram analysis, analysis of probability distribution functions (PDF) of fluctuations, wavelet analysis, structure function analysis (SF), and multifractal analysis using the rank ordered multifractal analysis (ROMA).

INA is optimized for the analysis of magnetic field and plasma data provided by Venus Express, Cluster and Ulysses satellites, but has also adequate modules for reading and analyzing other data types.

On the 25th September 2016, Dr. Lucia Aurelia Popa, senior researcher at the Institute of Space Science (ISS), became a full member of the International Academy of Astronautics (IAA) at the Basic Sciences Section.

The award ceremony took place in frame of the 67th International Astronautical Congress in Guadalajara, Mexico.

Dr. Lucia Popa is the Romanian representative of the Planck and Euclid ESA’s Missions and has been a Corresponding Member of IAA for three years, since 2013.

Celebrating 30 years of PRODEX

On September 5th and 6th 2016, PRODEX is organising an event for the “PRODEX 30th anniversary” at the ESA’s Space Research and Technology Centre, ESTEC, in Noordwijk, The Netherlands.

Created in June 1986, PRODEX (PROgramme de Développement d’Expériences scientifiques) offers institutions and industry the chance to work on ESA experiments. The programme works to help countries to get returns on their investments, and to promote scientific and industrial excellence and competitiveness.

The PRODEX Programme is an open programme. ESA Member States, as well as non-Member States, can become participating states. Romania became the 16th full ESA member state in 2011, and joined the PRODEX Programme in 2012. The PRODEX Participating States are 12 in total, reprezentated by Switzerland, Ireland, Belgium, Norway, Austria, Denmark, Hungary, Czech Republic, Greece, Romania, Netherlands, Poland.

In the presence of the PRODEX team and delegates from participating countries, Dr. Lucia Popa, seniour researcher at the Institute of Space Science (ISS), is invited to give a talk on the PRODEX project “Romanian Contribution to the Science Ground Segment of the Euclid Mission”. The detailed program of the event can be found here.

ISS signed a PRODEX Institute Agreement in September 2015, which enhance the project contributions in the field of space science to the PRODEX Programme.



Flag raising Ceremony for Romania at CERN


On 5th of September 2016, in the Globe of Science and Innovation at CERN, Geneva, Switzerland, takes place a great ceremony in the presence of His Excelency Mr. Klaus Iohannis, President of Romania, including national institutional representatives and romanian scientists, marking the accession of Romania as a Member State of CERN (the European Organization for Nuclear Research, the world’s leading laboratory for particle physics).

This is a memorable day, since Romania became the 22nd Member State of CERN on 18th July 2016.

However, bilateral contacts began back in 1991, when a scientific and technical cooperation agreement was signed between CERN and the Government of Romania, establishing the legal framework for later developments. Presently, Romania has particularly strong involvement in several LHC experiments, like ATLAS, ALICE and LHCb, with main contributions from the National Institute of Physics and Nuclear Engineering “Horia Hulubei” and the Institute of Space Science (ISS).

ISS is part of the ALICE Collaboration since 2006, and has a long-standing experience in the study of Quark Gluon Plasma produced in heavy ion collisions at relativistic energies. The ISS-ALICE group, consisting of 6 physicists and 3 guest scientists, has various activities related to jet and flow analysis, offline production management and software service tasks, GRID maintenance and operation in frame of the ALICE Collaboration. ALICE (A Large Ion Collider Experiment) is one of the four large experiments operating at the Large Hadron Collider (LHC), dedicated to study the properties and behaviour of the strongly interacting matter, at the very high temperatures and energy densities reached in ultra-relativistic collisions.

Launch of the First Orbital Telescope for the detection of ultra-high energy cosmic rays induced air showers

On Thursday, April 28, the TUS telescope aboard the Lomonosov satellite was successfully launched from the Vostochny spaceport. Lomonosov along with two other satellites, Aist-2D and SamSat-218, were carried into orbit by an unmanned Soyuz-2.1A rocket, the first rocket to fly from the new Russian spaceport.

The TUS (Tracking Ultraviolet Set-Up) orbital telescope aboard the Lomonosov satellite will detect Extensive Air Showers (EAS) produced by Ultra-High Energy Cosmic Rays (UHECR) and contribute to the study of the energy spectrum and arrival distribution of the cosmic rays with energies above 1020 eV.

“It is one more important step towards UHECR measurements from space!” said Pavel Klimov from the Skobeltsyn Institute of Nuclear Physics, Moscow State University, one of the lead scientists in the collaboration.

In 2013, a team of scientists from the Institute of Space Science lead by Dr. Maria Haiduc joined the TUS collaboration and signed a protocol with the Skobeltsyn Institute for Nuclear Physics to this effect. The involvement of the ISS team in the TUS collaboration is concerned with the development, together with a team form the Joint Institute of Nuclear Physics lead by Dr. Leonid Grigorievich Tkatchev, of a ground-based high-power LED UV light system to be used for the orbital calibration of the TUS telescope.

The TUS telescope can be regarded as a pathfinder for the future space-based UHECR detectors (e.g. KLYPVE, JEM-EUSO) and will gather preliminary data that will be extremely useful for the fine-tuning of the operational parameters of these future missions.

Scientists have developed a technique to use quasars – powerful sources driven by supermassive black holes at the centre of galaxies – to study the Universe’s history and composition. To demonstrate the new method, based on a relation between a quasar’s luminosity at X-ray and ultraviolet wavelengths, they made extensive use of data from XMM-Newton X-ray observatory of the European Space Agency (ESA). This approach promises to become an important tool to constrain the properties of our Universe.
