Reusability doesn't make sense to a rocket company for one big reason, jobs. Lets say a company has ten guaranteed launches per year and they had a rocket which can be used ten times. They would build exactly one rocket per year. That makes no sense. They can't possibly tell their teams: 'Goodbye, see you next year!'

The general public don't really care that much about spaceflight(even the SpaceX hypemachine is mostly confined to geeks/nerds), so NASA has probably started doing more desperate things to get public support. I'm just surprised that it took them this long.

Yeah it’s pretty crazy, with Mars 2020/ Curiosity clone (soon to have a proper name) from NASA, Huoxing-1 orbiter/small rover combo from China, ExoMars rover from Europe and Russia and UAE’s Hope orbiter all heading to the red planet during this window. However, although Mars 2020 and Hope are pretty solid, both ExoMars and HX-1’s chances of reaching Mars this cycle are questionable, considering the former is having parachute troubles which could delay the launch to 2022 and the latter can only launch on a LV with a questionable record...
