Mars is the fourth planet from the Sun. It is named after the Roman god of war and is often described as the ‘red planet' due to its red appearance. This red tint is caused by a mineral called iron oxide, which is very common on the surface of Mars. Olympus Mons is the largest mountain in the solar system and it is found on Mars.
Saturn is the sixth planet in the solar system and is famous for the rings which surround it. Saturn is one of the planets known as a ‘gas giant' because it is mainly composed of the gases hydrogen, helium and methane. Saturn has many moons, the largest of which are Titan and Rhea.
Neptune can only be seen through a large telescope and was not discovered until 1845. It is the eighth planet from the Sun and is also a ‘gas giant', as it is mainly composed of hydrogen and helium. It takes Neptune 165 Earth-years to orbit the Sun.
Pluto was once described as the ninth planet in the solar system. However, in 2006, it was agreed that it should be classed as a dwarf planet rather than an official planet in the solar system.
Read the facts about some planets in the solar system. For each question, choose the correct answer.

Which planet was discovered in the mid-nineteenth century?
1. Ever wondered what life was like on another planet? How about on Mars? NASA is looking for volunteers to explore life on the red planet for a whole year.
2. Actually, people won't actually be heading up to Mars. They will spend a year in a ‘Martian world' here on Earth. Grace Douglas, a lead scientist for NASA said, “Simulations on Earth will help us understand the physical and mental challenges astronauts will face before they go.”
3. The people chosen to take part in the experiment will be expected to live as astronauts would. That means carrying out spacewalks, communicating with mission control, working together as a team and eating space food! NASA has said that only healthy American adults between the ages of 30 and 55 can apply for the opportunity. They must also have a mathematics, science, pilot or engineering background to be considered.
4. The building where the experiment will take place is being made by a 3D printer and will be very realistic. Onboard, there will be no windows and very limited contact with the outside world in order to make it as realistic as possible.
5. So, what do you make of this ‘out of this world' experiment?
