summary
Jet Propulsion Laboratory ground software validates uplink command generation and packaging for unique spacecraft by combining a mission‑independent core with mission adaptations, running >1,000 automated tests plus exploratory tests, simulators and hardware clones; Curiosity has ~3,000 commands with ~1,000 used regularly, producing about 10^27 permutations if brute forced, so testers pick high‑risk combos, check flight rules, and rehearse on the mars yard and clone—flight software tested on clone and no priority 1/2 bugs to date.
