The SPHEREx mission, short for Spectro-Photometer for the History of the Universe, launched into space on a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California. The $488 million observatory will map the entire celestial sky, observing hundreds of millions of galaxies in 102 different infrared colors to gather information about their composition, density, temperature, and chemical makeup. By using spectroscopy to analyze this data, researchers hope to understand how galaxies form, trace the origins of water in the Milky Way, and unravel events that occurred after the Big Bang around 13.8 billion years ago. The launch of the spacecraft had been postponed several times due to concerns with the rocket and weather conditions at the launch site. In addition to the SPHEREx observatory, four suitcase-sized satellites were also deployed to study the sun. The two-year mission of the SPHEREx observatory will provide valuable insights into the early moments of the universe and help scientists piece together the history of how the universe evolved. The data collected by the observatory will shed light on the mysteries of the cosmos and contribute to our understanding of the universe’s formation and evolution.
