If humans go to Mars and have a similar positioning system there, knowing about ionosphere effects will be important. |
Since the Martian atmosphere is different in some ways, we can take theories that have been developed in the terrestrial case and test whether they work on Mars as well or whether there are areas that need improving. |
The energy of the X-ray photons is so great that once absorbed by the molecule they eject an electron from the atom, leaving an ion behind. |
