Conservationists (or anyone else who objects) will have it easy. Interplanetary missions are sensitive to timing. All you have to do is disrupt the launch schedule for a few weeks, then boom, it's another few years before they can even try again.

The United States and the West is not the world. Maybe you can file a couple of lawsuits and get an injunction against a US launch, but try that in China and the best case scenario for you is that nothing happens to you, and the scenarios get progressively more, ah, "interesting" for you from there.
