1. Why does CORI choose a supernova remnant to visit in order to refuel the xenon tanks? ANS:
Supernova explosions provide the energy to fuse elements heavier than iron. Xenon, with 54 protons in its nucleus, is much heavier than iron and will be produced only in a supernova explosion. Therefore, the remnant of a supernova is an excellent place to find xenon. REF: REF: Mission 4
2. What eventually happens to the material that is blasted out into space as a result of the supernova?
