The Institute of Space Science was represented at the LISA Consortium Meeting – LISA Phase A Activities, which took place between January 29th – 30th, 2018, at the Max-Planck Institute for Gravitational Physics (Albert Einstein Institute), in Hannover, Germany, by Dr. Ion Sorin ZGURĂ, Director of the Institute of Space Science, Dr. Laurențiu Ioan CARAMETE, Head of the Cosmology and AstroParticle Physics Group and Dr. Eugeniu Mihnea Popescu, Head of the High Energy Astrophysics and Advanced Technology Group. The status of the future LISA space mission, which is an L-type (Large) mission of the European Space Agency, was presented, as well as the foreseen contributions of each entity in the consortium.
The Laser Interferometer Space Antenna (LISA) will be the first space-based gravitational wave observatory and it will consist of 3 satellites joined by laser interferometers, placed in a triangle, at a distance of 2.5 million kilometers that will follow the Earth in its orbit around the Sun for an in-depth study of the Gravitational Universe. The satellites will have similar characteristics with the LISA Pathfinder mission, which flew successfully in December 2015 and has tested the most important technical components.
The Institute of Space Science will contribute to the LISA space mission with the Constellation Acquisition Sensor (CAS) system, which will verify the alignment of the 3 satellites, ensuring the acquisition of the laser signal on the interferometric detectors. Together with the Coarse Star Tracker (STR) system, CAS will check the visualization of the laser signal at the scanning maneuver stage. This contribution is fully supported by the Romanian Space Agency (by the programs “Romanian Incentive Scheme”, PRODEX and national programs) and is in excellent agreement with the Institute of Space Science strategy, as well as with the national strategy of research and development in Romania.
At the express request of the LISA Consortium, the Romanian Space Agency (ROSA) appointed as representative in the “LISA National Agency Board” (which has representatives from each national space agency in the consortium) Dr. Marius-Ioan Piso, president and CEO of the Romanian Space Agency, who is recognized by the scientific community as one of the main initiators of gravitational radiation research since the ’80s. Also, Dr. Ion Sorin ZGURĂ, Director of the Institute of Space Science was appointed as delegate member in the LISA National Agency Board.
LISA space mission is proposed by an international consortium made by researchers from Germany, Italy, Switzerland, United Kingdom, Spain, Denmark, Holland, Romania, Belgium, Portugal, Sweden, Hungary and United States of America. The launch of LISA is foreseen in 2034, with a lifetime of the mission for 4 years and the possibility of an extension up to 10 years.
