More About the SPHEREx Space Telescope - cosmology

According to NASA JPL/Caltech,the Spectro-Photometer for the History of the Universe,Epoch of Reionization and Ices Explorer (SPHEREx) mission will provide the first all-sky spectral survey.The results will be publicly accessible.Over its planned two-year mission,the SPHEREx Space Observatory will gather data on more than 300 million galaxies and more than 100 million stars in the Milky Way to ascertain the origins of the universe.The spacecraft will survey the sky in both optical and near-infrared light.The data will be used to search for the building blocks of life,water and organic molecules,in the Milky Way's stellar nurseries where stars are born fron gas and dust,as well as disks around stars where planets form.*The mission will create a map of the entire sky in 96 color bands,far exceeding the color resolution of previous all-sky maps.It will also identify targets for more detailed study by the James Webb Space Telescope and the future Nancy Grace Roman Space Telescope.*The spacecraft is being manufactured by Ball Aerospace,a division of Ball Corporation.Besides JPL/Caltech and international scientists,the SPHEREx team includes scientists from UC Irvine;Ohio State U.;the Harvard-Smithsonian Center for Astrophysics;Arizona State U.;the University of Arizona;Rochester Institute of Technology;Argonne National Lab;and Johns Hopkins University.SPHEREx will gather enough data to keep scientists busy for years.* BALL Corp (BALL)

About Ion Thruster Engines - physics

According to NASA,the most common propellant used in ion propulsion is the heavy neutral gas Xenon,which is easily ionized and has a high atomic mass,thus generating a desirable level of thrust when ions are accelerated.The thrusters work by using an electrical charge to accelerate ions from Xenon fuel to a speed 7-10 times the speed of chemical engines.An ion is defined as an atom or molecule that has gained or lost one of its valence eletrons,giving it a net positive or negative electrical charge.So it is a charged entity,as opposed to a neutral one.

This Thruster can Propel a Spacecraft Almost Indefinitely - Science Channel - physics

An ion thruster engine has been chosen to propel the NASA/ESA Gateway space station in lunar orbit.
