Beijing, February 17, Science and Technology Daily (Reporter Liu Xia) According to a recent report on the official website of the National Aeronautics and Space Administration (NASA), the agency plans to launch the "Space History, Reionization Epoch Spectrometer and Ice Explorer" (SPHEREx) in 2023. This space mission to study the origin of the universe will help astronomers understand the evolution of the universe and whether the components of life are ubiquitous in our galactic planetary system.

learns that the new mission is planned for two years at a cost of $242 million (excluding launch costs). NASA Director Jim Bridenstine said: "I am very excited about this new mission, which will help us further reveal the mysteries of the universe."

SPHEREx will use technology adapted from Earth satellites and Mars spacecraft to conduct optical and near-infrared surveys of the entire sky every six months. Although the human eye can not see near infrared light, it can be used as a powerful tool to study cosmic problems. SPHEREx will use 96 different color bands to map the whole sky, so the color resolution of the new map is much higher than that of the previous all-sky map. Researchers will use the mission to collect data on more than 300 million galaxies and more than 100 million stars in the Milky Way. In addition, the mission will look for water and organic molecules, which we know are essential for life. It will also identify more detailed research targets for future missions, such as NASA's James Weber Space Telescope and the Wide Field Infrared Survey Telescope. "This amazing mission will be a unique data repository for astronomers," said Thomas Zobqin, deputy director of NASA's Science Mission Council. It will provide an unprecedented map of the Milky Way, containing the'fingerprints'of the first moments of cosmic history. We're going to get one of the greatest mysteries of Science - new clues about what makes the universe expand rapidly in less than a nanosecond after the Big Bang.

p>NASA's Astrophysical Explorer Program submitted proposals for a new mission in September 2016. The Explorer Program is NASA's oldest continuity program, designed to provide frequent, low-cost space access. Starting with Explorer 1 in 1958, the project has launched more than 90 missions, among which the Universal Background Explorer was launched in 1989 and eventually won a Nobel Prize. <<
