What other existing, deployed spacecraft can/should have their    
   missions extended?   
      
   "NASA has announced that it will extend the missions for two of its    
   interplanetary explorers launching during the last decade—the Juno    
   spacecraft orbiting Jupiter and the InSight lander on the surface of Mars.   
      
   The Juno extension means the spacecraft will now operate in the Jovian    
   system through 2025. This will effectively transform the spacecraft from    
   a mission to study Jupiter into a full-fledged Jovian system explorer,    
   complete with close flybys of several of Jupiter's moons as well as its    
   system of rings.   
      
   Back in the inner Solar System on the surface of Mars, the InSight mission    
   will now run through December 2022. During these additional two years,    
   the lander will continue to operate its seismometer to identify    
   Marsquakes, as well as continue to collect detailed information about    
   weather at the surface.   
      
   After determining that both missions had done exceptional science to date,    
   an independent review panel recommended extensions of both to NASA.    
   "The Senior Review has validated that these two planetary science missions    
   are likely to continue to bring new discoveries and produce new questions    
   about our solar system," said Lori Glaze, director of the planetary science    
   division at NASA Headquarters in Washington."
