People have been walking on the surface of Mars for more than a century, in fantasy. Now, however, the possibility is so real that many people think that the question is not whether humans will go to Mars, but when they will go, how they will get there and who will go first.
Although there is a growing agreement that reaching Mars will be some kind of multinational effort, a prosperous nation, like the United States, seems capable of such an achievement by itself. For the US it is a political priority. The cost of the project has been estimated at 6 billion dollars, about double the price of the Apollo Moon project.
Of all the other planets in the solar system, Mars is the most like Earth. With about half the Earth's diameter, with one third of the gravity and only one percent of the atmosphere, space vehicles have found that Mars hides an important amount of water under its surface and in its frozen poles. While Venus is closer, with an average temperature of about 850 degrees, it is hostile.
From the presence of water and a relatively moderate climate comes another powerful attraction. The fascination with Mars centres around the issue of life. Mars is key to answering that critical question:
Is there life somewhere other than the Earth?
Answer the questions:
1. Is reaching Mars only a scientific challenge? Why?
2. What is the most interesting reason for exploring Mars?
True or False?:
1. Mankind has actually set foot on Mars.
2. Reaching Mars can cost as much as reaching the moon.
3. Mars is the same size as the Earth.
4. Venus's climate is gentle.

Hi Antonio! I see you continue to participate in the blog. Very well!!
You should revise the answer to the first question. It is not entirely correct.
And all the sentences are false. Although Mars is the most similar planet in size to the Earth, it has half the diameter.
Go on this way!

Jejeje. If he says it... But if you continue to put "to" after "must" I don't know if I will pass you ;)
