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

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," says NASA Administrator Jim Brittenstein. "Not only extends the US Navy's powerful fleet based on space missions dedicated to revealing the secrets 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 card containing fingerprints from the first moments of the history of the universe, and we will have new clues about one of the greatest mysteries in science: What drives the universe to expand as fast as a nanosecond after a 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 set goals for more detailed exploration from future missions, such as James Webb and NASA's Space Telescope.

The NASA Astrophysics Research Program requested new missions in September 2016. Nine proposals were presented and two mission concepts were selected for further exploration in August 2017. The SPHEREx conceptual research proposed the best scientific potential and, the workable development plan.

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

The aerospace industry in Burnfield, Colorado, will provide the spacecraft SPHEREx and
mission. Institute of Astronomy and Space Sciences in Korea
Daejeon, the Republic of Korea, will contribute to test equipment and science

The NASA program,
run by the Goddard Space Flight Center in Greenbelt, Maryland,
the oldest uninterrupted program of the agency designed to provide frequent and cheap
access to space through research-driven scientific research conducted by the researcher
Astrophysics and Heliophysics at NASA
Missions Directorate.

The program has
launched more than 90 missions, starting in 1958 with Explorer 1, which
have discovered the radiation belts on Earth. Another exploration mission, The Space Behavior, launched in 1989, led to
Nobel prize.
