In the past when Mars had a dense atmosphere it was warmer and water could exist on the surface.

Article II of the Outer Space Treaty states, “Outer space, including the moon and other celestial bodies, is not subject to national appropriation by claim of sovereignty, by means of use or occupation, or by any other means.” In short, nobody can claim ownership of Mars or land on Mars, or do so with any other …

However, the surface is not hospitable to humans or most known life forms due to the radiation, greatly reduced air pressure, and an atmosphere with only 0.16% oxygen. Human survival on Mars would require living in artificial Mars habitats with complex life-support systems.

• Have there been any signs of life on Mars?
• How does a planet lose its atmosphere?
• What’s the chance of an asteroid hitting a base?
• Do you think there is life on Mars right now?
• How would you terraform Venus?

After the Earth, Mars is the most habitable planet in our solar system due to several reasons: 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.

What are the Benefits of a Mars Colony?

• Mars is the most accessible planet in the solar system.
• Exploring Mars may possibly answer origin and evolution of life questions.
• Mars could someday be a destination for the survival of humankind.
• There is the possibility of discovering new life that could impact life on Earth.

If you want to send a spacecraft all the way to Mars, first you’ll need a fast rocket to escape the pull of Earth’s gravity. The heavier your spacecraft, the more powerful your rocket needs to be to lift off. Next, make sure you launch at the right time. Mars and Earth orbit the sun at different speeds and distances.

NASA has always launched spacecraft at the optimal time so they can take advantage of the Hohmann transfer orbit, which is the fastest way we know to send something to Mars without anyone on board.

about 24,600 mph

One that can approach relativistic speeds. We can execute missions to Mars, but it takes several months for a vehicle to reach the Red Planet. In short, we can propel individual particles to near light speed inside particle accelerators, but haven’t expanded that technology to the macro level.

Advertisement. The idea is to yoke a small probe to a solar sail, orbit a laser array, and push the probe toward its destination at speeds far in excess of anything we can attain these days. Lubin estimates a probe weighing only a few hundred pounds could be accelerated to Mars using this method in just three days.

It takes the Earth one year to orbit the Sun and it takes Mars about 1.9 years ( say 2 years for easy calculation ) to orbit the Sun. The elliptical orbit which carries you from Earth to Mars is longer than Earth’s orbit, but shorter than Mars’ orbit. So it takes nine months to get to Mars.

So, a day on Mars is 24.6 hours. Since this planet is farther from the Sun than Earth, one revolution of Mars around the Sun is a longer trip. So, a year on Mars is 687 Earth days. Mars is about half the size of Earth.
