Euclid Has 8 Extra Years of Fuel. A Scientist Has A Brilliant Plan To Use It.

It’s almost become expected that many space telescopes and probes can have “extended missions”. Both Voyagers are still sending data back 40+ years after their 5-year primary mission ended. But figuring out what to do with those spacecraft after their primary mission takes some negotiation.
