DescriptionThe nano satellite was developed and built by the Romanian Space Agency (ROSA). When the project began, the developers of this satellite were still in college. The satellite is cube-shaped and has a mass of 1 kilogram, and its dimensions are 10 cm on each side. It is built on a Cubesat platform.[3] The satellite carries out three scientific tasks: micrometeorite flux measurements, cosmic radiation flux measurements at LEO and Earth surface imaging via a 3 megapixel camera. The project was funded and supported by the Romanian Ministry of Education and the European Space Agency. LaunchAlthough the initial launch was planned for 2008, the project had been postponed due to some issues with the carrier rocket, Vega. The satellite was successfully launched on 13 February 2012 from the Guiana Space Centre, together with LARES and other CubeSat satellites from other European countries.[4] As of 26 February 2012, it appeared that the satellite had not settled into the orbit properly. Due to a malfunction to its stabilizing system, it was expected that the satellite would spin uncontrollably and eventually get lost in space. However, the coordinator of the project, Mugurel Bălan stated that the situation was under control.[5] The agency managed to make contact with the satellite on 18 February 2012 but only briefly to receive some basic parameters, however it was unable to get its systems running. Contact was lost permanently shortly afterwards. The satellite re-entered the atmosphere on 2 January 2015 and disintegrated.[6] References1. ^{{cite web|url=http://planet4589.org/space/log/launchlog.txt|title=Launch Log|first=Jonathan|last=McDowell|work=Jonathan's Space Page|accessdate=31 October 2013}} {{Portal|Spaceflight}}{{Orbital launches in 2012}}2. ^{{cite web|url=http://www.n2yo.com/satellite/?s=38080|title=GOLIAT Satellite details 2012-006D NORAD 38080|work=N2YO|date=31 October 2013|accessdate=31 October 2013}} 3. ^Historic moment: Goliat, first Romanian satellite in space, to be launched in February - Bucharest Herald (25 January 2012) - Retrieved 16 February 2012. 4. ^ESA Press Kit - Vega qualification flight VV01 (pdf) - Retrieved 16 February 2012. 5. ^{{cite web|url=http://www.realitatea.net/are-primul-satelit-romanesc-zilele-numarate-inca-nu-s-a-stabilizat-pe-orbita_917207.html |title=The first Romanian satellite hasn't stabilized on the orbit yet |language=Romanian |accessdate=4 March 2012 |deadurl=yes |archiveurl=https://web.archive.org/web/20120229083700/http://www.realitatea.net/are-primul-satelit-romanesc-zilele-numarate-inca-nu-s-a-stabilizat-pe-orbita_917207.html |archivedate=29 February 2012 |df= }} 6. ^{{cite web|url=http://jurnalul.ro/stiri/observator/cum-si-a-omorat-romania-primul-satelit-construit-la-preturi-astronomice-explicatiile-halucinante-ale-sefului-agentiei-spatiale-romane-rosa-632262.html |title=Cum şi-a omorât România primul satelit, construit la preţuri astronomice.
