The SOLAR/SOLSPEC instrument, installed on the SOLAR payload on board the International Space Station, has performed between 2008 and 2017 Solar Spectral Irradiance (SSI) measurements from the UV to the NIR. It was an upgrade version of SOLSPEC launched in the 80’s and 90’s for SPACELAB, ATLAS, and EURECA missions. We will present the highlights of the 9-year SOLAR mission. The requirements for such long term space mission is a robust instrumentation, an absolute calibration, a full radiometric characterization for any degradation of performances in space environment. The SOLAR/SOLSPEC design, the pre-launch and in-flight performances will be presented. The results are a new reference solar spectrum (at low and high resolution), with particular interest on the SSI level in the NIR band, measured in space up to 3 µm and confirmed by ground-based validation campaigns. Ongoing work concerns the UV variability during solar cycle 24. Perspectives for new instrumentation and lessons learned from the SOLAR mission will also be presented.
