Mars is the fourth planet from the sun. Mars is about half the size of Earth and has two moons. It’s surface is red and made up of Carbon Dioxide, so bring an oxygen tank. Although Mars does have seasons, the temperature only varies from cold to extremely cold. It’s impossible for water to get on Mars, so there will be no way to live on Mars’ surface without a protected heating suit, water, and cooked food. You might want to bring a blanket or two to sleep in. Mars is bigger than our home planet called Earth. Make sure you travel in a spacecraft that has plenty of heat and bring an experienced astronaut with you!
