SOLAR SYSTEM

Detailed explanation-1: -Mars Pathfinder was launched December 4, 1996 and landed on Mars’ Ares Vallis on July 4, 1997. It was designed as a technology demonstration of a new way to deliver an instrumented lander and the first-ever robotic rover to the surface of the red planet.

Detailed explanation-2: -Mars Pathfinder / Sojourner Rover The Mars Pathfinder mission, designed to demonstrate a low-cost method for delivering a set of science instruments to the Red Planet, was the first wheeled vehicle to be used on any other planet in the solar system and served as the foundation for the Mars rovers of today.

Detailed explanation-3: -The name Sojourner was chosen for the Mars Pathfinder rover after a year-long, worldwide competition in which students up to 18 years old were invited to select a heroine and submit an essay about her historical accomplishments.

Detailed explanation-5: -NASA’s Mars Pathfinder was designed primarily to demonstrate a low-cost way of delivering a set of science instruments and a free-ranging rover to the surface of the Red Planet. Pathfinder demonstrated a number of innovative, economical, and highly effective approaches to spacecraft and mission design.

Detailed explanation-6: -What was NASA’s Mars Pathfinder mission? On July 4, 1997, NASA landed a spacecraft on Mars, Pathfinder, for the first time in about two decades, following the successful Viking 1 and 2 missions.
