The 2020 Decadal Survey in Astronomy & Astrophysics has placed pursuit of a new constellation of GREAT OBSERVATORIES as the top national priority for the future of space astrophysics.
The first Great Observatories are among the greatest missions in scientific history.
They revolutionized our understanding of the cosmos.
They were triumphs of human ingenuity.
They embodied the spirit of peaceful international partnership...
 
 
...while securing U.S. Leadership in Space Science for decades.
They brought awe and wonder to our world.
 

 They reminded us of our place in the cosmos.

They inspired a new generation of explorers.

 

 

 It is the twilight of

the Great Observatories.

Only two remain.

 

JWST and Roman will

complete their missions by 2040.


A scientific golden age will end.



 

This is why Astro2020 named pursuit of

as the top national priority for the future of space astrophysics.

 

 

Astro2020 calls for three Great Observatories

to pursue the greatest cosmic frontiers of the coming decades…

 
 
 
 
 
 

 

…which, with the combined power of two mighty telescopes on Earth…

 

 
 

Will make the greatest scientific discoveries of the century.

 

Astro2020 lays out an innovative new plan to build these revolutionary engines of discovery

 

The three NEW GREAT OBSERVATORIES

… capitalize on the largest and most detailed concept study investment in the history of NASA Astrophysics

The Great Observatories can launch in time to seize the future of discovery.

We can secure it by growing NASA’s Astrophysics budget.

 

The NEW GREAT OBSERVATORIES will be a whole-of-Nation effort.
 

They will prevent evaporation of talented national workforces and transfer core competencies from one generation to the next.

 

Will spark a new golden age of cosmic discovery.

Inspire a new generation of explorers.

Secure U.S. leadership in space science for decades.

Prevent evaporation of talented national workforces.

Transfer core competencies from one generation to the next.

Pursue the greatest questions in all of existence:
