|Yes you can! On your bike son!
Yes it is certainly scientifically possible. See links on terraforming and in particular Mars.
If the sun exploded (went into supernova), then I highly doubt that terraforming of ANY world in our Solar system would be enough to save us from the catastrophic explosion of the Sun.
Terraforming is the (as yet) untried process of converting an alien landscape into one more Earth-like. For example, a plan to seed the atmosphere of Mars with oxygen and let geology and evolution gradually convert Mars into a human-habitable planet would be considered terra-forming.
Mars does not have large bodies of liquid water on its surface like Earth does. There is evidence to suggest that Mars once had liquid water on its surface in the past, but it has mostly evaporated or frozen over time. Today, any water on Mars exists mostly in the form of ice or vapor.
To make Mars habitable, the most feasible solution would be to artificially create a thicker atmosphere through terraforming, potentially by releasing greenhouse gases to trap heat and promote warming. This could potentially allow for liquid water on the surface and protection from harmful radiation. Establishing sustainable habitats and ecosystems with technologies such as bioengineered organisms could also contribute to making Mars more habitable for humans.
Some major obstacles to terraforming Mars include its thin atmosphere, lack of a global magnetic field to shield it from solar radiation, and the absence of a significant greenhouse effect to trap heat. Additionally, the low temperatures and lack of liquid water on the planet pose significant challenges to creating a habitable environment for humans.
That's a possibility, but scientists are being extremely careful not to do that yet - because if there is any life on Mars now, it would almost certainly be wiped out if we started terraforming Mars. So we don't want to risk it until we're fairly certain that Mars has no life of its own.
Launching algae and anaerobic bacteria to Mars for terraforming could have unintended consequences on the planet's ecosystem and could potentially harm any native life forms that may exist. It is essential to thoroughly study and understand the Martian environment before introducing foreign organisms. Additionally, international scientific and ethical guidelines would need to be followed to ensure responsible terraforming practices.
If you start when you are 30 you would probably be 32. But if you want to start at 30 you better be under 10 today.
Carl Sagan suggested back in 1993 that we should strike Venus with large asteroids, in an attempt to eject the inhospitable atmosphere away from the planet.
Terraforming is transforming a planet into one that is similar to Earth (so that an ecosystem in which humans can survive will sustain itself).
