And if the "Musk+Bezos = 138 #Mars2020 missions" hypothesis seems an exaggeration, here is an alternative for #Ingenuity and #MarsScienceHelicopter fans:
• #Ingenuity demo cost $0.085B including 1 month operation
• #MRO (the mission that carries the #HiRISE camera producing the images we use in maps), cost $0.716B + $0.031B/y
• A Martian GPS, consisting of 24 MRO class satellites *separately* launched from the Earth, at $1B/pc + $0.1B/y operation, cost $26B/20y
