NASA has announced plans to launch the SPHEREx satellite on a SpaceX Falcon 9 rocket in February 2025. The launch will take place from Vandenberg Space Base in California, opening a major mission to explore the structure and history of the universe.
The SPHEREx satellite is designed to survey millions of stars and galaxies in the vastness of space. The satellite's main mission is to create a comprehensive map of the sky, allowing scientists to better understand the expansion of the universe after the Big Bang - one of the most important phenomena in the history of the formation of the universe that scientists are always trying to decipher.
During its two-year mission, SPHEREx will produce two detailed maps of the sky each year. These maps will provide important data that will help researchers explore how galaxies form and evolve over time. NASA expects the mission to yield a rich trove of data that will aid in a deeper understanding of stars, galaxies, and the spatial structure of the universe.
In addition, SPHEREx is also tasked with searching for essential molecules such as water and carbon dioxide in dust clouds in the Milky Way. These are important compounds involved in the formation of stars and planets, helping scientists understand more about the chemical processes that take place in space.
Data from SPHEREx will be used to create detailed spectral maps, recording the light from millions of objects in the universe. Scientists will analyze the data to explore evolutionary patterns of galaxies and better understand the history of the development of large structures in the universe.
NASA stressed that the partnership with SpaceX on this project is an important part of NASA's strategy to enhance its space exploration capabilities. SpaceX's Falcon 9 rocket has become a reliable launch vehicle for many of NASA's major science missions, helping to reduce costs and optimize launch schedules.
If all goes according to plan, the SPHEREx mission will be one of the largest sky-mapping projects ever undertaken, contributing to humanity’s understanding of the origin and evolution of the universe. NASA plans to release more details about the mission’s development and key stages as launch approaches.
