What do you think about space travels?
Do you know how many millions of dollars does one trip cost? or is it billions? How many times has a man landed on the moon? when?
Can there be life in Mars? why not?
Why is it so interesting to travel to Mars?
Is our planet going to be inhabitable forever? why?
How many times has man landed on the moon?
There have been 6 manned travels to the moon. Press here for info.
How much would I have to pay for a flight into space?
Depending on where you're going, a ticket could set you back anywhere from $250,000 to tens of millions of dollars.
If you're looking simply to cross the 62-mile-high Karman line that marks the boundary between the upper atmosphere and outer space, Virgin Galactic says it will take you there for $250,000. The company says about 650 people already have tickets for the suborbital flights, to be made aboard a winged vehicle called SpaceShipTwo. A date for customer flights has yet to be announced.
The world's first private astronaut, a wealthy American engineer named Dennis Tito, reportedly paid $20 million to spend eight days in space in 2001. More recently, Guy Laliberté, the co-founder of Cirque du Soleil, shelled out $35 million for an ISS trip in 2009. Space Adventures still advertises Soyuz flights and plans to start booking trips to the ISS aboard Boeing's Starliner.
Can there be life in Mars? why not?
There are no final answers on the matter but there is no proof of any type of life on mars at the moment, scientists are trying to find out whether there was life at some point before but it is still an ongoing research. Read here for more information.
The interesting question is wheter Mars can be inhabitable or not. Read here to find out.
Why is it so interesting to travel to Mars?
After the Earth, Mars is the most habitable planet in our solar system due to several reasons:
Its soil contains water to extract
It isn’t too cold or too hot
There is enough sunlight to use solar panels
Gravity on Mars is 38% that of our Earth's, which is believed by many to be sufficient for the human body to adapt to
It has an atmosphere (albeit a thin one) that offers protection from cosmic and the Sun's radiation
The day/night rhythm is very similar to ours here on Earth: a Mars day is 24 hours, 39 minutes and 35 seconds
Is our planet going to be inhabitable forever? why?

The Sun is gradually getting hotter. Eventually it will be hot enough to evaporate all Earth's oceans, and cause a runaway greenhouse effect that sends temperatures soaring upwards. This process might begin in about a billion years, and would wipe out all but the most resistant microorganisms.
