In a number of months, the area company will choose two of the 4 missions to totally fund, every with a value cap of $450 million and a launch late inside this decade. For the shedding concepts, there could also be extra probabilities in future years—however till new alternatives come up, scientists can solely plan, wait, and hope.
This is kind of how NASA has achieved planetary science for many years. Scientists give you all method of nice concepts to reply questions on our Photo voltaic System; then, NASA broadcasts a possibility, a feeding frenzy ensues for these restricted slots. Finally, one or two missions get picked and fly. The entire course of usually takes a few a long time from the preliminary concept to getting information again to Earth.Learn 34 remaining paragraphs | Feedback
