They concluded that this earth was devoid of civilization‚ possibly due to an asteroid attack. It was also inferred that this asteroid attack annihilated living beings on this planet and this lead to an absence of control over the spaceship while it was stationed over Jupiter. They returned to the spaceship. The sun was reddish orange on the horizon. The

The benefits of space exploration are vital to our rapidly advancing world. One can say that the benefits resulted from space exploration can better ensure the safety and wellness of individuals‚ and to the well-being and survival of mankind‚ as there are useful spin-off technologies‚ sophisticated satellite technologies‚ and advanced space travelling technologies that can save human lives. I agree for the continuation of space exploration due to these benefits‚ as they greatly exceed any of the

Finally‚ I am going to end this with my opinion on pluto. Pluto definitely
