The Korea Astronomical Research Institute announced on the 6th that it has begun development of the world’s first’all-day infrared image spectroscopy space telescope (SPHEREx)’ together with the National Aeronautical and Space Administration (NASA) Jet Propulsion Research Institute (JPL).
SPHEREx, which will be launched into space in 2024 to perform its mission, will detect 102 infrared wavelengths to observe the sky in 360 degrees. Twelve institutions and companies, including Moon-Yeon Cheon, NASA, California Institute of Technology (Caltech), and the company’Ball Aerospace’, will jointly participate. Cheonmunyeon is the only institution outside the United States.
Moon-Yeon Cheon is in charge of developing a’cryogenic vacuum chamber’ to be used in the space environment test of a telescope and software that analyzes observation data. The’Linear Spectroscopic Filter’, the payload of the next-generation small satellite 1 in Korea, developed earlier by Moon-Yeon Cheon, is also used in SPHEREx.

SPHEREx collects three-dimensional spatial information of the universe and 3 billion individual celestial bodies information through’image observation’ that simultaneously observes a wide area and’spectral observation’ that measures changes in brightness according to the wavelength of individual celestial bodies, and evolves the universe. It is expected to contribute to unraveling the secret of A NASA official said, “SPHEREx is a breakthrough attempt to make a mark in the history of astrophysics.”
Dr. Woong-Seop Cheon, head of research on the Korean side, said, “I was able to participate in this joint development because of the experience of independently developing the payload of the next-generation small satellite 1 in the past.” “He said.
