Tierney wrote a better article than I could Tuesday about why the legacy for the ages that can happen in our lifetimes is the first footprints on Mars. The sponsor could be remembered as the next “Prince Henry the Navigator, King Ferdinand, [or] Queen Isabella”. This is an argument I implied here in a scholarly way and in passing here in a grandiose way and a whimsical way here. In the process I attempt to refute Jeff Bell and James Van Allen who are both opposed.
