QUBE-II is a German technology demonstration satellite developed for the Federal Ministry of Research, Technology and Space[1][2][3][4][5][6] based on an 8U CubeSat bus[7] by the Lithuanian company NanoAvionics.[8] The mission's goal is to demonstrate quantum key exchange between a small satellite and a ground station.[9][10][8][11][12] The satellite includes a 2.5U Laser Communication Terminal (LCT) based on instruments flown on precursor missions CubeISL (launched in 2021) and QUBE-I (2024).[13] The mission's consortium was led by OHB and included DLR, FAU, LMU, and ZFT.[7] QUBE-II was launched on 3 May 2026 on the Falcon 9's CAS500-2 rideshare mission.[14][15][16][17][18]
