1963-Mariners 4, 6 and 7
flew past Mars taking pictures of the entire planet and then sending them back to earth. Each spacecraft had 2 goals to achieve while on the Red Planet. 1;to measure the amount of toxins in the atmosphere, 2; to take lots of high quality photos of Mars, so scientists could have a better understanding of what the planet is like. -
June 20th-September 7th 1976-Viking 1 and Viking 2
orbited around and landed on Mars. The Viking 1 consisted of two parts, an orbiter and a lander. The orbiter, while in space, took pictures of the Martian surface. After the pictures had been taken, a landing site was chosen. -
November 13th, 1981-Canadarm
was sent into space. The arm could move its shoulder, elbow, and wrist joints all at once. Even though your hand may shake when you reach for something, it is not accepted for the Canadarm. One wrong move by the arm, and a part for the ISS could be lost. -
December 4th, 1996-Sojourner
landed on Mars, the Martian planet. The Sojourner was a pathfinder, missioned to Mars. It was a six-wheeled lander that was controlled by an Earth based operator. It’s mission was simple, to analyze rock and soil samples. -
April 19th, 2001-Canadarm2
was launched into space and attached onto the international space station. The Canadarm2 assembled the International Space Station (ISS) while in space. The 17 meter long arm, can move anything you could imagine, supplies, equipment and even astronauts. -
2008-the Special Purpose Dexterous Manipulator (Dextre)
was attached onto the ISS. (International Space Station) Dextre has one purpose on the ISS, to keep it ship-shape. The robotic arm does quick jobs like changing batteries and replacing cameras outside of the ISS. Since Dextre was attached onto the International Space Station, the astronauts on board have had much more time for the main goal of the ISS, science. -
2010-the ISS
was in space and fully functional. A total of 161 spacewalks have been done in support of space station assembly totalling more than 1,015 hours of space walking. The ISS is solar powered. It uses solar power because it is much easier to get the energy and power from the sun in space, rather than an electric outlet. -
June 10th,2003 and July 7th 2003-the spacecrafts Spirit and Opportunity
were launched, it arrived on Mars January 4th ,2004. The purpose of the rover was to examine closely the chemical ingredients of the rocks and soil. While the data is still being collected and analyzed, results have shown that water did exist at some time on Mars.
