The outer planets are called gas giants and have a diameter of greater than 48,000 kilometers. It's made of iron, nickel, and sulfur. Oddly-shaped Deimos is covered in loose dirt that often fills the craters on its surface, making it appear smoother than pockmarked Phobos. That is the point in Mars' orbit when it comes closest to Earth in 2022, it was about 50.6 million miles (81.5 million kilometers) from our planet. Heres an example of recent Missions to Mars, and the years they launched: See the trend? Every 15 to 17 years we witness very close Mars oppositions when Earth passes between Mars and the sun during Mars' perihelion (closest point to the sun). Practically, this means that you can only begin your trip when Earth and Mars are properly lined up. Today, water on Mars is found in the form of water-ice just under the surface in the polar regions as well as in briny (salty) water, which seasonally flows down some hillsides and crater walls. We take a look at how long a trip to the Red Planet would take using available technology and explore some of the factors that would affect your travel time.
