MMSAT-1 (also known as Lawkanat-1) was a Burmese 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.[5] 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.[5] It was deployed into orbit on 22 March 2021.[3]

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.[6][5] According to Hokkaido University, as Myanmar did not yet have the necessary equipment, the satellite would initially be operated from Japan.[7]

MMSAT-1 reentered the atmosphere on 4 April 2023.[8]
