Be careful with this....
Nasa and ESA did this mistake once and a Mars probe did not land so smoothly....
Nasa used imperial units and ESA metric so the control systems were not communicating properly so the Probe hit the surface not at 1 feet / sec but something like 100.000 miles/hr, and this made it to not such a very smooth landing.... there were a lots of sad faces in Houston and John F. Kennedy space center that day
Wonder if they ever heard of integration testing and system acceptance test
