Those messages refer to the moons, not the planets. But yes, the last model I installed expired Jan 1 2021. The models were generated by an observatory in France, the details escape me at the moment but there's another thread on here somewhere where someone was trying to track it down and get updates. There are separate files for moons of mars, jupiter, saturn and uranus named mars.1020 etc (where 1020 means the model is good from 2010 to 2020). Once you get the new model files in auxil, each instance of use_bdl() in the four corresponding *moon.c source code files also needs updating to accept the new date range of the models. Or better yet, continue with my file naming convention and change the code to infer the file name automatically, then no future code changes would be required. Elwood
