ESTCube-2
open-in-new
<p>ESTCube-2 was a three-unit (1 U standard dimension 100x100x113.5 mm) <a href="/facts/CubeSat/jL2IpYKd">CubeSat</a> built by the Estonian Student Satellite Foundation. ESTCube-2 launched from Kourou, French Guiana, with the <a href="/facts/European_Space_Agency/L8YRNV0C">European Space Agency</a>'s <a href="/facts/Vega_(rocket)/AuH9mJ32">Vega</a> <a href="/facts/Launch_vehicle/g1GCGFJB">launch vehicle</a> on 9 October 2023 at 4:36 a.m. <a href="/facts/Eastern_European_Summer_Time/JvChT6Ex">EEST</a>. The satellite likely failed to deploy and was likely destroyed when the upper stage of the launch vehicle reentered the atmosphere. </p><p>ESTCube-2 was the second satellite in the ESTCube program (the first was <a href="/facts/ESTCube-1/TF16wHVd">ESTCube-1</a>). The satellite was completed in the first half of 2022. The development of the satellite started in January 2014, but the necessary team and funding were not obtained until 2016. ESTCube-2, like ESTCube-1, was an educational-scientific project that aimed to give university and high school students the opportunity to participate in the creation and completion of a space mission. Dozens of diploma theses were involved in the construction and development of the satellite. </p><p>The planned <a href="/facts/Altitude/B5eNVurK">altitude</a> of the ESTCube-2 orbit was 564 kilometers from the ground and the expected speed of the satellite in <a href="/facts/Orbit/nD2TPySG">orbit</a> was about 7.6 km/s. </p><p>Partners are the <a href="/facts/University_of_Tartu/eVN4IExF">University of Tartu</a>, <a href="/facts/Tartu_Observatory/JDoP0WP4">Tartu Observatory</a>, <a href="/facts/Finnish_Meteorological_Institute/EHmRaLYY">Finnish Meteorological Institute</a>, <a href="/facts/GomSpace/UlN7QAUf">GomSpace</a>, <a href="/facts/Milrem_Robotics/vMhD1rUm">Milrem Robotics</a>, Foresail, <a href="/facts/TU_Dresden/FtSpjB7n">Dresden University of Technology</a>, Captain Corrosion, <a href="/facts/European_Space_Agency/L8YRNV0C">European Space Agency</a>, <a href="/facts/European_Commission/Cc5JgbEI">European Commission</a> </p>
