"Open the Heaven's Gate"... Space Observatory 'SphereX' Goes [Space Now]

SPHEREx, a space observatory that explores the entire sky, including the history of the universe and the existence of water, will be launched on the 9th. After several delays, it will finally launch into space. SPHEREx



will collect data on 100 million stars and 450 million galaxies in the Milky Way over the next two years to explore the origin of the universe.



The mission is clear. SPHEREx will observe the entire sky to find out how the universe evolved. Through this, it will continue efforts to find key ingredients for life in the galaxy.



SPHEREx will search for water, carbon dioxide, carbon monoxide, and other key ingredients for life frozen on the surface of interstellar dust particles in gas and dust clouds where planets and stars are formed.



Instead of taking 2D images of the subject of observation, 3D data can be collected along the field of view. Scientists can see the amount of ice present in molecular clouds and observe how the ice composition of the entire cloud changes in different environments.

The division of roles between SpearX and the James Webb Space Telescope is also notable. The James Webb Space Telescope has investigated water, carbon dioxide, carbon monoxide, and various compounds in hundreds of objects.



On the other hand, SpearX is an observatory that surveys galaxies on a large scale. If SpearX is called a "macroscopic observatory," James Webb is a "microscopic telescope.



" A NASA official explained, "SpearX is a survey telescope designed to study a large part of the sky relatively quickly," and "The results can be used together with data from target telescopes such as James Webb."



In other words, "If SpearX finds an interesting location, James Webb can study that object with higher spectral resolution and wavelengths that SpearX cannot detect," and added, "The two telescopes can form a very effective partnership."



SpearX surveys the entire sky every six months. The SphereX, which our country's Korea Astronomy and Space Science Institute jointly participated in developing, was originally scheduled to launch on the 28th of last month, but has been postponed several times.



An official from the Korea Aerospace Science Administration said, "The launch of SphereX, which was originally scheduled to launch on March 8th, has been postponed by one day to perfectly prepare the launch vehicle, and is now aimed for 12:09 p.m. on the 9th (Korean time)." SphereX will be launched from the Vandenberg Space Force Base in California, USA, aboard SpaceX's Falcon 9 launch vehicle.
