The Korean Astronomy and Space Science Institute (KASI) is involved in a wide range of technology and astronomy projects. They operate a very long baseline interferometry network within Korea and jointly with other Asian facilities that among other things, utilizes a multi-band quasi optical input duplexer developed by Han. This allows simultaneous observations of multiple SiO masing transitions between 40 and 130 GHz. They also have a 14m millimeter telescope used for mapping molecular clouds in the 115 Ghz CO line and in other molecular emission. The institute is also involved in rocket projects with Caltech and have recently joined a consortium of Asian countries supporting and observing at the Caltech Submillimeter Observatory in Hawaii. KASI also has numerous technology development programs.
