I'm surprised we havn't seen a Venus mission announcement. China should be rounding out its inner planetary science capabilities at this stage. A venus mission should be less technically challenging than mars, but allow CNSA and other agencies to round out capabilities in designing probes for different environments and architectures. Hopefully china can do a hardened surface lander (non-rover) with a high altitude balloon orbiter on a first mission.
I would like to see a manned venus orbiter mission prior to an attempt at manned Mars landing. This should provide experience and learning opportunity prior to mars mission.
