Well, we certainly do lead everyone else as far a robotic probes. Our robots are becomeing more advanced
also. In that area it looks like Japan is our only major competitor. They have started working on a
Quadruped also. They intend on putting it on the moon by 2025. Of course they will use Space X
to get it there, unless someone else can do it better. Which is starting to look doubtful.
Elon Musk can dang sure build rockets. He is the 21st century Howard Hughes, and just as crazy lol.
