Planetary Journal
Life on Mercury would be... Impossible, as the planet is constantly bombarded by CME's, solar flares, and magnetic radiation from the sun.
Life on Venus would be... Impossible,as the planet has an average temperature ranging from 13˚c to 202˚c, and the atmosphere is corrosive.
Life on Mars would be... Possible, although people would have to live in a city inside a space-proof bubble , have daily shipments of oxygen, and melt the polar ice caps and separate the water from the carbon dioxide.
Life on Jupiter would be... Impossible, as the planet has no solid surface.
Life on Saturn would be... Impossible, as the planet has no solid surface.
Life on Uranus would be... Impossible, as the planet has no solid surface.
Life on Neptune would be... Impossible, as the planet has no solid surface.

Alpha City

N.A.H.S have built a city on Mars! A team of experts were sent to each of the planets to find out if it was possible to inhabit other planets. The team of 4 people came back with the information that the only planet in the solar system (apart from Earth) that was suitable for human habitation was none other than the planet Mars! The project to build the city, which scientists have named Alpha, began on the 1st of January 2007. The city was finished on the 29th of August. The city is situated near the North Pole, which scientists have decided to name Cato. N.A.H.S are looking for people who are prepared to leave Earth and go and live in Alpha. The price for transportation (this includes the shifting of your furniture) is $20,000. The cities committee has decided that there will be no money in Alpha, as everything you need will be supplied directly to your doorstep. Spaces are limited, as the city can only hold 33,597 people. You will be able to visit your family regularly. As the ships move at a rate of 2 times the speed of light, it will only take 28 hours for you to go to Earth.
