NASA is an independent agency that uses the latest science and technology that is accountable for the civilian space programs along with the continuous research on aeronautics and aerospace. This organization is known for its extraordinary missions and discovery of new researches. Recently, it has chosen a mission in their space agency Explores Program that is going to give you a foretaste of the past. This program provides the flight prospects investigations of physics, heliophysics, and astrophysics. It is expected to launch in the year 2023.
This recent mission to be taken place by NASA is to provide a glimpse of the past to the world. The name of this mission is SPHEREx, which stands for Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer. The mission will explore the enormous number of galaxies that existed in the past with the latest technology instruments that will use the technique of utilizing optical and near-infrared light. This mission is supposed to see as far as possible in the past that is about 10 billion years. This will enable the researchers to find some answers about the galaxy of stars, which are close to the planet Earth, across the Milky Way. The organization will use a spectrophotometer in order to perform all the surveys of the sky, which will measure with near-infrared spectra from 0.75 to 5.0 micrometers. This simple instrument will observe the sky by mapping it four times. The telescope lens has a diameter of 20 centimeters with a width of 3.5º x 7º field view, forming an image on the four 2k x 2k mercury cadmium telluride photodetector arrays. Galaxies will be classified according to their redshift accuracy and about 450 million of galaxies are categorized. NASA will be using a technology new and unique to research the ancient galaxies.
The main motive of this mission is to satisfy the queries which arise in a human mind while speaking of the term galaxy. This curiosity urged NASA to find reasons for which factors were responsible for the early universe’s inflation and exploring the origin of the universe. SPHEREx also tends to find how the galaxies are connected with one another and the origin of the water in the systems of planets. This mission will survey the region of atmosphere using the technology science adapted by the satellites of the planet Earth and spacecrafts of Mars. It will create a chart of sky in 96 different color bands. This is greater than the previous technologies used in all the sky maps. This mission will definitely be marked as an elaborated study on future missions of the organization. For this vast project, The Korea Astronomy & Space Science Institute has decided to contribute the test equipment along with the analysis of science `
According to NASA’s associate administrator Thomas Zurbuchen, this extraordinary mission will be a treasure key of unique data for astronomers and will also be providing an aid for the future use. The launch of this mission is expected by the year 2023 with James Bock of Caltech being in charge along with a collaboration of NASA’s Jet Propulsion Laboratory, Ball Aerospace and the Korean Science Institute. The mission will enlighten the enthusiasm of stargazers, which has been dimed by the farewell of Mars rover Opportunity. A potential for new wonders and discoveries can be seen using the latest science and technology, in the year 2023.
