'''MMSAT-1''' (also known as '''Lawkanat-1''') was a Burmese [[Microsatellite (spaceflight)|microsatellite]] launched to the [[International Space Station]] (ISS) on 20 February 2021 and deployed into orbit from the ISS on 22 March 2021. It was Myanmar's first microsatellite and jointly built by Japan's [[Hokkaido University]] and [[Myanmar Aerospace Engineering University]].<ref name="reuters" /> It was delivered to the ISS by the American cargo spacecraft [[Cygnus NG-15]]. MMSAT-1 was temporarily held on ISS and its deployment was delayed due to the [[2021 Myanmar coup d'état]].<ref name="reuters">{{cite web |last=Kelly |first=Tim |url=https://www.reuters.com/article/us-myanmar-politics-satellite-japan-excl-idUSKBN2B41O1 |title=Exclusive: Myanmar's first satellite held by Japan on space station after coup |work=[[Reuters]] |date=12 March 2021 |access-date=21 July 2022}}</ref> It was deployed into orbit on 22 March 2021.<ref name="jaxa">{{cite web |url=https://iss.jaxa.jp/kibouser/provide/j-ssod/72631.html |script-title=ja:これまでに放出された超小型衛星 |trans-title=Microsatellites released thus far |publisher=JAXA |date=23 March 2021 |access-date=21 July 2022 |language=ja}}</ref>

MMSAT-1 was intended to be used not only for environmental observation and mineral exploration, but also for natural disaster control, but human rights activists worried that the satellite could be used for military purposes.<ref name="dw">{{Cite news |date=19 March 2021 |title=Myanmars erster Satellit bleibt zunächst in der ISS |trans-title=Myanmar's first satellite remains in the ISS for the time being |url=https://www.dw.com/de/myanmars-erster-satellit-bleibt-zun%C3%A4chst-in-der-iss/a-56929285 |access-date=21 July 2022 |work=Deutsche Welle |language=de}}</ref><ref name="reuters" /> According to Hokkaido University, as Myanmar did not yet have the necessary equipment, the satellite would initially be operated from Japan.<ref>{{Cite news |date=23 March 2021 |title=»Lawkanat-1«: Japan setzt umstrittenen Satelliten für Myanmar im All aus |trans-title="Lawkanat-1": Japan deploys controversial satellite for Myanmar in space |url=https://www.spiegel.de/wissenschaft/weltall/japan-setzt-umstrittenen-satelliten-fuer-myanmar-im-all-aus-a-3d6e37ed-1f2a-4e74-8a7b-19b9cc13e57f |access-date=21 July 2022 |work=Der Spiegel |language=de}}</ref>
