To learn how galaxies grow and evolve during cosmic time, including understanding how gas is expelled and expelled from galaxies, we will need to develop a set of observatories, missions and multiple wavelengths. All this is possible in the plan established by the Decadal Astro2020 survey. However, all this is based on NASA’s astrophysics and the NSF land facilities that are fully financed during the 2020s and beyond. (Credit: National Academies/Astro2020 Decadal Survey)
NASA’s astrophysics, which gave us Hubble, Jwst, and much more, faces its greatest budget cut in history. All future missions are at risk.
This “Fleet Graph” catalogs each NASA science mission in the fourMain subdivisions (Earth science, heliophysics, planetary and astrophysical science) that is active from July 2024. Many more planned and future missions are in several stages of development. (Credit: NASA science fleet graph)
This map encoded by mission colors performed or co -crocked by NASA’s astrophysics shows several past, many current and a large number of future missions that are anticipated that they will become part of NASA’s astrophysical fleet, assuming that it does not have to resist a budget of more than 50% in 2025 and beyond.

Together with the terrestrial facilities, which can only observe a portion of the electromagnetic spectrum, space -based observatories, such as the fleet of multiple wavelength observatories launched and maintained by the NASA astrophysical subdivision of the NASA’s direction of the Science Science Mission, can reveal the spectacular fashion universe, often as never before.

Both hubble (upper) and JWST (lower) are reflecting telescopes. The light of distant objects enters the telescope, reflecting the great primary mirror that sends it to the smallest secondary mirror. The secondary mirror reflects that it turns on through a hole in the primary mirror where it focuses on an approach and enters each of the many instruments of the telescope located behind the primary mirror. Telescope diagrams cannot be climbed, but the JWST position 1.5 million kilometers of the earth, unlike the distance of ~ 500–600 km of the land hubble, represents a big difference in the temperatures in which observatories can operate.
