Humans have been fascinated with space for centuries. Mayans made a calendar from the stars, Galileo made a telescope, and a man was put on the moon. Space is vast, and scientists still don’t know a lot about it. Is space worth still exploring? Now that the space race has died down, does humanity need to continue to learn about space?
"Yes, we should explore space"Show moreShow less
Space is a subject that the world has only a small understanding of. There are many theories about what exists in space, but only a few have been proven. Perhaps if space was successfully explored in its entirety, scientists could uncover new planets and stars that could potentially be used to the Earth's advantage.
In studying Earth and its climate, we have only Earth itself as a model. By sending probes to other planets in the solar system scientists can gain more in-depth and useful information about planetary evolution. Venus, for instance, seems to have undergone a runaway global warming effect. We can use this information to help Earth's ever-growing climate change situation.
By studying Venus, researchers might be able to better understand the processes which take place during a long period of planetary climate change. Those same researchers may be able to partner with engineers and environmentalists to better control and handle the climate crisis here on Earth. 
Studying Mars, Earth's closest planetary neighbor, would allow an array of different types of scientists to apply the knowledge they find in the field to life on Earth. According to NASA, the main goal with a Mars exploration would be to discover whether or not humans can live for extended periods beyond low Earth orbit.  If something is in low Earth orbit, or LEO, then it is within 2000 km of the Earth's surface. Continuing to explore space and other planets within the solar system can allow scientists to better understand Earth, and make future predictions about climate change.
[P1] Exploring nearby planets would give us a deeper understanding of the Earth and the physical benefits or consequences of space exploration in general.
[P2] Scientists can study other planets and use that information to better understand Earth.
Rejecting the premises
[Rejecting P1] Space exploration is such an exclusive field that the theoretical benefits of the practice itself would never really benefit humanity as a whole.
