The sun changes, Mars is easier to live than Earth?

People in the future will have to develop a plan to shift Earth's orbit to avoid the predicted solar boom. Meanwhile, the position of Mars is suitable for life.

In an article published in The Conversation , Dr. Matteo Ceriotti - Expert in Space Engineering Systems of Glasgow University (Scotland), once participated in bombardment programs to change the asteroid trajectory. , Earth defense - analysis: By 1 day, we will have to move the Earth to a more livable position - near Mars or move to the red planet itself, which will be a beautiful location, easier to live in the hot future of the Solar System.

According to the latest studies, in the next few billion years, our Sun can run out of fuel and explode into a supernova, and swallow up some of the closest planets, including Earth. Before that event occurred, the Earth people were forced to prepare in advance to deal with the extreme global warming that the Sun changed, which could cause extinction.

The best option is to move our planet to another orbit where the existing Mars position is the best . "We have devised techniques to move small objects - asteroids - from their orbit for many years, mainly to protect our planet from impacts" - Dr Ceriotti said. But this cannot apply machinery to the Earth because it causes severe damage to moving objects and the Earth is very large.

Actually, the Earth used to be moved many times with very small impact so we haven't realized it yet. That's when launching a probe leaving Earth, the launch has transmitted a small pulse to Earth in the opposite direction. With current technology, SpaceX's 300 billion world-class FalconX missiles are needed to push Earth to Mars. However, we can hope for the advancement of technology.

The next option is to use "solar sails" , an option that is being studied to design long-term, solar-powered engines for other planet-exploration spacecraft in the future. It could be understood that it was like a giant sail collecting momentum from sunlight that was brought together. However, we will need a sail 19 times larger than Earth's diameter, " drifting" for 1 billion years with current technology.

In addition, the technique that the famous Rosetta spacecraft used to reach comet 67P in 2014-2016 can also be applied. It has twice visited the Earth neighborhood in 2005 and 2007. Applying the principle of two objects revolving around each other to exchange momentum and change velocity like a billiard ball of planetary level, Rosetta Has received a significant acceleration to reach the target. If we repeat many times, use a spacecraft to impact large asteroids, so that these asteroids replace Rosetta's position every year, the reciprocal effect can gradually push the old orbit away. .

The final option is to move our entire species onto the planet that will gradually warm, up to the standard of living in the Sun's explosion."It doesn't sound very difficult," concluded Dr. Matteo Ceriotti.
