The first scientific data from "SiriusSat-1,2" satellites was received

From August 28 to September 3, 2018, the first series of payload activations of the scientific and educational satellites SiriusSat-1 and SiriusSat-2 was conducted. Data of measurements of scientific instruments are received and deciphered.

The payload of the SiriusSat satellites is the detector of charged particles and gamma radiation developed in the Nuclear Physics Institute of the Moscow State University and jointly created by the Institute of Nuclear Physics of the Moscow State University and the SPUTNIX company. The detector is a scintillation spectrometer made on the basis of an assembly of a plastic scintillator and crystals CsI (Na) and CsI (Tl), which has a sensitive area of ~ 4 cm2. Daily information of each of the satellites is about 1 MB.

 

Satellites «SiriusSat-1, 2» were launched from ISS into outer space on August 15th 2018 during the planned extravehicular activity on the International Space Station. 

The satellites were assembled by school students in collaboration with specialists of «SPUTNIX» based on nanosatellite platform «OrbiCraft-Pro» (designed by «SPUTNIX» Ltd). The platform standard international size CubeSat 1U. Satellites «SiriusSat» improved due to launch specification: equipped with a handle for cosmonaut, bendable antennas, manual activation system, also specially equipped with removable protective covers and soft transport containers. Weight of each satellite with a handle is 1.45 kg. Base size net of opened state antennas - 130x131x236 mm. The payload of satellites consists of cosmic ray detectors meant to research «space weather». The ray detectors were developed by Lomonosov Moscow State University Skobeltsyn Institute of Nuclear Physics (MSU SINP). The data acquired from the ray detectors will be useful in circumterrestrial space studies and when monitoring radiological environment.

The satellite assembled by school students in the Center of Gifted Education «SIRIUS» in Sochi was demonstrated to the President of Russian Federation Vladimir Putin during his visit to «SIRIUS» in July 2017. Back then, the students asked Vladimir Putin about a possibility to launch their satellite.

As a part of cooperation program with Center of Gifted Education «SIRIUS», State Space Corporation «Roscosmos» and S.P. Korolev Rocket and Space Corporation «Energia» assisted in organizing the launch of satellites «SiriusSat-1, 2» to the orbit, the Innovation Promotion Fund has provided a financial support for the assembling of nanosatellites. Before shipping to the ISS the satellites went through all screening procedures on the base of Center of Gifted Education «SIRIUS» and S.P. Korolev Rocket and Space Corporation «Energia». Nanosatellites «SiriusSat-1, 2» with other cargos were delivered to the ISS via transport vehicle «Progress MS-09» on July 10th 2018. 

At the present time Center of Gifted Education «SIRIUS» continues its work on the next series of «SiriusSat» satellites.
