The World Space Observatory-UV (WSO-UV) is an international collaborative project aimed at providing UV astronomy capabilities in the post-Hubble Space Telescope (HST) era. Planned for launch in the early 2010s, WSO-UV will operate for 5 years with an option for a 5-year extension. The mission is based on a 1.7-meter telescope, T-170M, optimized for UV observations, and will include high-resolution spectrographs, long slit low-resolution spectrographs, and imaging cameras. Key instruments include the High Resolution Double Echelle Spectrograph (HIRDES) and the Long Slit Spectrograph (LSS), as well as the Field Camera Unit (FCU) for imaging. HIRDES offers high spectral resolution (R~50,000) and sensitivity comparable to HST/COS, while LSS provides low-resolution spectra in the 102-320 nm range. The FCU will cover the far UV (FUV), near UV (NUV), and near UV-visual (UVO) regions, with high sensitivity and large fields of view. The mission aims to address the gap between HST and future large UV telescopes, complementing the James Webb Space Telescope (JWST) in wavelength coverage. The spacecraft will be placed in a geosynchronous orbit at 35,800 km altitude, with contributions from Russia, Germany, China, Italy, the UK, and Spain.The World Space Observatory-UV (WSO-UV) is an international collaborative project aimed at providing UV astronomy capabilities in the post-Hubble Space Telescope (HST) era.
