Mars is amazing. It is said that of all the planets of the solar system, Mars is most like Earth, but smaller. We always wondered if humans could live there. Mars has some very impressive relief, because of high mountain ranges and deep craters. The highest mountain is a volcano called Olympus Mons. Mars is covered with dust because, over millions of years, it is buffeted by strong winds that cause soil erosion. These winds are responsible for the formation of dunes in North poles on Mars! By cons, in other places, the winds drove the dust, leaving completely bare rocks. Mars is farther from the Sun than Earth. It is cold and dry climate.

Mars is called the red planet, because of all the rocks that cover it contain oxidized iron and give it a red color.

They plan to send astronauts to Mars by 2030.

The Time on a Planet

A year is the time that a planet takes to describe an orbitre around the Sun. A day is the time it takes a planet to rotate or to do a complete revolution around its axis.

You adapt quietly to life on board of the International Space Station. They confide to you your first task: to maintain the station, which is to dusting, vacuuming, cleaning filters, install new software and do upgrades. You spend too much time to train, because the muscles are deteriorating rapidly, when little or no gravity. Exercise prevents the weakening of muscles. Finally, you participate in scientific experiments. These experiences may include crystal growth and require the handling of chemicals. Briefly, there is something to keep you busy during your six months aboard the International Space Station.

Important Data Box: A day on board of the Space Station

In general, astronauts follow a regular work schedule, as on Earth. They work 8-hour periods on weekdays and half days on Saturdays. Sunday is off!

This pie chart shows you how astronauts spend their time.

The International Space Station takes one hour and a half to make a complete orbit around the Earth. This means that, after sunrise, the astronauts have only 45 minutes of light before the sun sets again. Then they plunged into darkness for 45 minutes, when the station is on the face of the Earth opposite the Sun.

Help yourself to a clock to answer the following questions.

1. The sun rises at 4:47. Give the time of the next three sunrises on board of the space station. (2 pts)
