NASA has chosen a new mission to study the origin of the universe

HOUSTON – TECH – NASA chose a new space mission that will help astronomers understand how our universe evolves and how often they are lifetime components of our galaxy's planetary systems.

The mission of the Spectro-Photometer for the History of the Universe, the Age of Reionization and the Ices Explorer (SPHEREx) is a planned two-year mission, funded at $ 242 million (excluding marketing costs), and scheduled to begin in 2023.

"I am really excited about this new mission," said Jim Brindstedin, NASA Administrator. "Not only does it expand the US space-based mission-based space mission dedicated to revealing the mysteries of the universe, it is an important part of a balanced science program that includes missions of varying sizes."

SPHEREx will explore the sky in both optical and near-infrared light, which, although not visible to the human eye, serves as a powerful tool for responding to cosmic issues. Astronomers will use the mission to collect data for more than 300 million galaxies and more than 100 million stars in our Milky Way.

"This incredible mission will be a treasure trove of unique astronomy data," said Thomas Zurbuben, a lawyer at NASA's Science Mission. "This will provide an unprecedented galactic map containing" prints "from the first moments of the history of the universe. And we will have new clues about one of the greatest mysteries of science: What made the universe expand as fast as a nanosecond after the big bang? "

SPHEREx will explore hundreds of millions of galaxies close and far, some light that takes so long, takes 10 billion years to reach the Earth. In the Milky Way, the mission will seek water and organic molecules – important for life, as we know – in stargate nurseries, areas where stars are born of gas and dust, and discs around stars where new planets can be formed. ,

Every six months, SPHEREx will explore the entire sky using the Earth's satellites and the Mars spacecraft. The mission will create a whole-sky map in 96 different color strips, far beyond the color resolution of the previous maps of all skies. He will also identify goals for more detailed exploration from future missions, such as the James Webb Space Telescope and NASA.

The NASA Astrophysics Research Program requested new mission proposals in September 2016. Nine proposals were presented and two mission concepts were selected for further study in August 2017. After a detailed review by a NASA group and external scientists and engineers , NASA decided that the SPHEREx Conceptual Study offered the best scientific potential and the most feasible development plan.

The chief investigator of the mission is James Bock of the Caltech Institute in Pasadena, California. Caltech will work with NASA's JPL to develop a payload for the mission. JPL will also manage the mission.

Ball Aerospace in Burnfield, Colorado, will provide a SPHEREx spacecraft and a mission. The Korean Institute of Astronomy and Space Sciences in Daejeon, Republic of Korea, will contribute to test equipment and scientific analysis.

The NASA Explorer program, run by the Goddard Space Flight Center in Greenbelt, Maryland, is the agency's longest-running program designed to provide frequent and inexpensive access to space using space science studies related to astrophysics and heliophytes at a directorate NASA's "Science Mission".

The program launched more than 90 missions, starting in 1958 with Explorer 1, which opened the Earth's radiation belts. Another research mission, The Space Phantom, launched in 1989, led to the Nobel Prize.
