Astronomy Science ~ Uranus will be interesting to visit, but staying there will be very difficult. However, Its moons has a different story. Uranus has 27 known moons, and five satellites are often considered his greatest "major moons." If we want to establish a permanent base on the satellites of Uranus, Titania, and Miranda is a good target - Titania presents the strongest gravity (nearly 4 percent of the earth), and Miranda has a solid surface to be explored.

Because Voyager 2 is the only spacecraft to visit Uranus system, Earth society still do not know much about the moon planet. Pictures from Voyager 2 showed that the southern hemisphere of Titania has many craters and tectonic landforms, including valleys and faults, some of which could be an attractive location for a visit. The largest crater on Titania has a diameter about 203 miles (326 kilometers) and the longest canyon stretches more than 930 miles (1,500 km) from the equator to the poles almost to the south.

On the other hand, Miranda is very varied and mixed, resembles a puzzle that is not put together correctly. The strange formations called the corona, which is a grooved structure resembling oval racing circuit. He also has a crater plains are crisscrossed with large canyons and fracture.

Some rock fracture Miranda has a depth of about 12 times deeper than the Grand Canyon. Because gravity of Miranda was very low, (less than 1 percent of the Earth), the stone that fell from the cliff will take about 10 minutes to reach the bottom. This fault could be a pleasant place for thrill seekers. "I think it would be a little dangerous, but if we stay in Miranda may be some brave who want to jump off the cliff," said Jeff Moore, a planetary scientist at NASA Ames Research Center in California.

All the moons of Uranus does not have the weather, the color of the sky and the surface pressure is not there because the atmosphere is not there. They are also very cold: for example, the average temperature of about minus 334 Titania Fahrenheit (minus 203 Celsius). In addition to the deadly cold, it is not clear what else the danger that would be experienced in the moons of Uranus. They may have a month's earthquake, as well as cryo volcanism that could shake the ground. Radiation from charged particles produced by the magnetosphere of Uranus can also cause problems, especially if you live on the side of the moon facing away from the planet (the side facing Uranus Titania and Miranda at any time).

Titania took almost nine days the earth rotates on its axis, while Miranda takes about 1.4 days. If you live on the equator of this moon, you can experience the day-night cycle that is normal, but it does not apply in the polar regions. Unlike other planets in the solar system, Uranus has an axial tilt of about 98 degrees. This means that during the course of the planets around the sun which took 84 years, the poles of Uranus and its moons experienced 42 years of exposure to sunlight and dark 42 years.

If you look at the sun through the filter of Titania or Miranda, he will appear as the disc is very small, such as a bright spot, said Moore. And if you are on the side of the moon facing Uranus, the planet will look great - Uranus will be seen approximately 41 times the size of our moon of Miranda, and about half of Titania. You can also see more of the major moons of Uranus Titania surface and Miranda. "All will form a large enough disk in the sky," said Moore. And if you send a message to Earth, radio signals would require an average time of about 2.5 hours to reach the Earth.
