NASA's Mars Pathfinder mission -- the first spacecraft to land on Mars in more than 20 years and the first ever to send a rover out to independently explore the Martian landscape – touched down on July 4, 1997 and initiated a new era of scientific exploration of the red planet.
Pathfinder's atmospheric entry and landing on the Martian surface were the centerpiece of the mission. After a fiery entry, the spacecraft released a large, billowing parachute to slow its descent through the thin Martian atmosphere. Then a giant cocoon of airbags inflated seconds before landing to cushion the spacecraft's impact. Sojourner, the small rover onboard Mars Pathfinder, is named after an African-American crusader, Sojourner Truth, who "travel(ed) up and down the land" advocating the rights of all people to be free during the American Civil War. The Pathfinder mission was a great success, providing scientists with large amounts of data, pioneering many new technologies, and demonstrating the feasibility of developing, designing launching and operating a planetary mission according to NASA’s new “faster, better, cheaper” philosophy. The identification of rounded pebbles and cobbles on the ground, and sockets and pebbles in some rocks, suggests conglomerates that formed in running water, during a warmer past in which liquid water was stable. This was confirmed with more detailed results from the Mars Exploration Rovers, Spirit and Opportunity. Modelled at 1:12 and 1:15 (if you want to display with Erik/Ton's Mars Rover). |
