The inherent me-too, tribal, dick swinging of space achievement makes me sad. Yes, Mars is hostile to landers and space stations take a bunch of work, but NASA's been landing bots on Mars and manning stations since the 70's, with 70's tech. What if ESA sent new experiments on existing landers and rovers? What if China sent up new modules to add onto the ISS? Then we'd all be building on each other's work and advancing humanity instead of reproducing it and re-learning 40 year old lessons.
