The microHETSat (micro- Hall Effect Thruster Satellite) is an ESA mission based on former SITAEL’s S-75 platform (microsatellite class, <75kg), designed to equip and operate a low power (100W class) Hall Effect thruster-based micro-propulsion system internally developed by the company in the frame of a dedicated IOD-IOV mission. In June 2023 microHETSat started its acceptance test campaign in view of the launch on board SpaceX’s Falcon 9 on December, 1st of the same year. The acceptance test campaign has been anticipated by a delta-qualification of the spacecraft’s Structural Model to verify the compatibility with Falcon 9 in place of the initially foreseen Virgin Orbit’s LauncherOne, which ceased its operations in March 2023. microHETSat has been successfully launched on expected date and it completed LEOP and Platform Commissioning phases, with green light for the start of the Payload Commissioning and nominal operations. The first part of the paper reports the acceptance campaign results of the microHETSat satellite, with a focus on the main activities performed before the delivery to the Vandenberg Space Force Base (VSFB) in California, US for the launch campaign: a. Structural model Delta-qualification for Falcon 9 b. Flight Model Vibration and TVAC test campaign c. Flight Model EMC and RF test in anechoic chamber In addition, a brief overview of the launch campaign is presented as conclusion of the spacecraft ground activity. The second part of the paper reports the outcome of the in-flight experience from the launch date to the completion of the LEOP and Platform Commissioning, with focus on: a. Mission Control Center (MCS) operations b. LEOP & Commissioning phases execution c. In-flight experience (nominal and contingency operations)
