## Editorial
LAPAN A-series microsatellite bus covers the Indonesian LAPAN-A2/LAPAN-ORARI and LAPAN-A3/LAPAN-IPB microsatellite line.[^gunter-lapan-a2][^gunter-lapan-a3][^wiki-lapan] The platform line is associated with BRIN through LAPAN's institutional succession and public LAPAN-developed microsatellite capability.[^wiki-lapan] The family is classified as mini because the instances span about 76 kg for LAPAN-A2 and about 120 kg for LAPAN-A3, with the larger instance setting the class envelope.[^gunter-lapan-a2][^gunter-lapan-a3] The platform family supported orbital Earth-observation, AIS, and amateur-radio mission roles, including LAPAN-A3/IPB multispectral imaging workflows.[^wiki-lapan][^lapan-a3-preprocess]
