What I want to know is.. when are they going to send a rover or lander which can test for biology? Like the viking landers from the 70s.. since then they've completely avoided sending any biology experiments to mars... despite finding water and other organic chemicals?
And yes, as someone else pointed out, why not make use of economics of scale and make multiple identical rovers and send them to multiple different places on the planet? It worked for Spirit and Opportunity, and instead of wasting so much money designing and building a new rover from scratch every time, build a more modular one and send many of them... even 1 every few years if 2 at once is too expensive. Modular so different experiences can be swapped in or out thus creating slightly different configurations or upgraded models ?
Why design and build from scratch every time and not just design a reliable base model, a lot like the Soyuz, and just slowly evolve it over time or fly it in slightly different configurations? I know a Soyuz capsule is nothing like a mars rover, but a soyuz capsule is human rated and still cheaper than a freaking rover. The same concepts could be applied.
