Transcript of Curiosity
Mars Science Laboratory mission is part of NASA's Mars Exploration Program, an exploration of the red planet. Curiosity's mission is to determine if the planet is habitable, or if it was habitable.
Curiosity was launched on November 26, 2011 and landed on Mars on August 6, 2012.
The duration of the mission was planned for a Martian year (about 2 years on Earth),but Curiosity is still on Mars.
To land Curiosity used the EDL method ( entry, descend, landing).
The Red Planet
Curiosity's large size allows it to carry many scientific experiments that will be able to zap, analyse and take pictures of any rock whthin reach of its 2-metre arm. Curiosity is about the size of a small sports utility vehicle. It is 3 metres by 2.8 metres wide, about 2.1 metres high and weighs 900 kilograms. Curiosity's wheels have a 50.8 centimetre diametre.
Engineers at NASA's jet Propulsion Laboratory designed the rover to roll over obstacles up to 65 centimetres high and to travel about 200 metres for day. The rover's power comes from a multi-mission power generator, which produces electricity from the heat of plutonium-238's radioactive decay.
If humans ever set foot on Mars they would feel much lighter. The Red Planet is smaller than Earth and has less surface gravity than the planet we call home.
On Mars you'd experience 62.5% less gravity than you’re used to on Earth, so if you weighed 100lbs on Earth, you would weigh only 38lbs on Mars.
You'd feel lighter on Mars
Mars is a cold desert world. It is half the diameter of Earth and has the same amount of dry land.
Our neighbouring planet’s Olympus Mons is a shield volcano that is three times the height of Mount Everest. It has a height of nearly 22km and a diameter of 600km.
It nearly occupies the same amount of area as mainland France, while scientists believe it may be still be active.
Like Earth, Mars has seasons, polar ice caps, volcanoes, canyons and weather, but its atmosphere is too thin for liquid water to exist for long on the surface. There are signs of ancient floods on Mars, but evidence for water now exists mainly in icy soil and thin clouds.
Journey to Mars
NASA is working to send humans to Mars in the 2030s. At the beginning, the Space Launch System and Arian will carry astronauts into the proving ground at deep space, including a Yeorlong mission.
They'll also conduct a robotic Mas mission for landing on and living on the Bed Planet.
