How earth as far as we know is the only planet that can sustain life?
A special planet: the habitable Earth It is the right distance from the Sun, it is protected from harmful solar radiation by its magnetic field, it is kept warm by an insulating atmosphere, and it has the right chemical ingredients for life, including water and carbon.
Is the exploration of space worthwhile pros and cons?

| Space Exploration Pros | Space Exploration Cons |
|---|---|
| Space travel provides endless opportunities | Implies significant air pollution |
| Humans can learn humility from space travel | Space travel implies waste production |
| May speed up technological progress | Radiation may be a problem |
Is space exploration a waste of time and money?
For: Investing in further scientific exploration of space is a waste of resources. The amount of money being spent on space research is in the billions and it has achieved extraordinarily little except for a bit of improved technology which would probably have come about anyway by other means.
How much does space exploration cost?
Jude. For NASA astronauts, McAlister says, orbital trips can have a $58 million price tag, based on averages calculated from commercial contracts with SpaceX and Boeing. While $58 million may seem like a lot, it’s actually a great bargain for NASA.

How much of the ocean have we explored?
Home Ocean Facts How much of the ocean have we explored? More than eighty percent of our ocean is unmapped, unobserved, and unexplored . Much remains to be learned from exploring the mysteries of the deep.
What is NASA doing to go beyond Earth orbit?
Today, NASA is moving forward with a new focus for the manned space program: to go out beyond Earth orbit for purposes of human exploration and scientific discovery. And the International Space Station is now a stepping stone on the way, rather than being the end of the line.
When will the Earth become uninhabitable?
The evaporation of the Earth’s oceans would be well underway by 1 billion years from now. We can assume that millions of years before this, Earth will have become uninhabitable. Life more complex than a bacterium has only been around for 600 million years, so it looks like we are about half way through the ‘Golden Years’.
How much of the ocean is still undiscovered?
More than eighty percent of our ocean is unmapped, unobserved, and unexplored. Much remains to be learned from exploring the mysteries of the deep. From mapping and describing the physical, biological, geological, chemical, and archaeological aspects of the ocean to understanding ocean dynamics, developing new technologies,…
