NASA and Japan launch rain-tracking satellite the U.S. should be concerned about their potential loss of international dominance in space exploration and travel. I think they should worry because anytime we are behind on technology and someone else isnt that is not a good thing for us and we need to start working harder to get ahead.
In the coming centuries we can be sure that hegemony in space will be one of our most valuable and hotly-contested commodities. America needs to be considering long-term plans for dominance of space and even colonization space on the Moon and Mars. It sounds far fetched but this society is approaching the point at which it can no longer be confined to Earth.
Space Exploration is very expensive and complex. It makes perfect sense that we team up with our allies to share the costs and risks. We cannot afford to go it alone in space anymore. Besides the benefits of space exploration should be shared becuase no one country will ever own outer space.
I do not think that NASA and Japan launching the rain tracking satellite should be something the USA should be concerned about in terms of losing their dominance in international space exploration and travel. I think that the USA will always be the leading power in terms of space exploration.
The United States does not particularly care about a "loss of international dominance" in this arena. For one thing, the Space Race of a half century ago was to show the USSR how far our missiles could fly. For another thing, all of today's spacefaring nations are basically using NASA technology. May we all benefit from the exploration of space.
