The lowest energy transfer to Mars is a Hohmann transfer orbit, a conjunction class mission which would involve a roughly 9-month travel time from Earth to Mars, about 500 days (16 mo) [citation needed] at Mars to wait for the transfer window to Earth, and a travel time of about 9 months to return to Earth.
The human species has significantly evolved during the last two centuries. Our population on Earth has exploded from about one billion to over seven billion people.And we've even changed ...
At least two-thirds of Mars' surface is more than 3.5 billion years old, and it could have been habitable 4.48 billion years ago, 500 million years before the earliest known Earth lifeforms; [4] Mars may thus hold the best record of the prebiotic conditions leading to life, even if life does not or has never existed there.

The timeline of human evolution outlines the major events in the evolutionary lineage of the modern human species, Homo sapiens, throughout the history of life, beginning some 4 billion years ago down to recent evolution within H. sapiens during and since the Last Glacial Period.

Mars reaches the same solar radiation flux as Earth today, after which it will suffer a similar fate to the Earth as described above. [99] 6.6 billion The Sun may experience a helium flash, resulting in its core becoming as bright as the combined luminosity of all the stars in the Milky Way galaxy. [120] 7.5 billion
In the 21st century, to combat overpopulation, Earth plans to colonize Mars. To terraform the planet, the surface is seeded with moss to create a more tolerable atmosphere and surface temperature. Cockroaches were also introduced to spread the moss. 500 years later, in the year 2599, a crew is sent in the BUGS 2 to clear out the cockroaches.
