Radio signals from the lander enabled scientists on Earth to precisely locate the spacecraft and, therefore, Mars itself. about 65 cm long by 45 cm wide and 32 cm high.

The purpose of Pathfinder was to prove that the concept of “faster, better and cheaper” missions would work. Each of the IMP's two cameras (two in order to get stereo images)
Most online reference entries and articles do not have page numbers. Pathfinder was the third spacecraft ever to land successfully on Mars; NASA’s Viking I and Viking II spacecraft were the first and second, in 1976. Pathfinder had two main objectives: first, to demonstrate that certain new and economical technologies could be used to explore the Martian surface, and, second, to perform scientific study of the area around the landing site. The U.S. mission Mars Polar Lander crashed near the Martian south pole in 2000, prompting widespread questioning of the claim—seemingly proved by Pathfinder’s spectacular success—that Mars missions could be built faster, cheaper, and better. This caused different forms of radiation to be emitted by the material, the amounts and characteristics of which could be recorded to reveal the composition of the material. The rover will also be able to
(JPL) will be supported by NASA's Deep Space Network (DSN). Lofted by a Delta-II rocket, Pathfinder consisted of a 795 lb (360 kg) lander and a 25 lb (11.5 kg) surface rover named Sojourner in honor of American abolitionist and ex-slave Sojourner Truth (c 1797–1883). chosen is in the Ares-Tiu Valles system. The hobbyist’s model rocket engine is an example of a solid rocket engine.

The spacecraft entered the Martian atmosphere on 4 July 1997 directly from its approach hyperbola at about 7300 m/s without going into orbit around the planet.

Beyond the air bag is the rock-strewn Martian surface. The Mars Exploration Rover (MER) mission began in 2003 when MER-A rover, Spirit, was launched on June 10, and MER-B, Opportunity, was launched on July 7; both headed to Mars. Introduction Pathfinder will be the first U.S. spacecraft to land on Mars since the two Vikings arrived in 1976.Pathfinder is likely to be joined on the Mars surface in 1997 by two landers and two penetrators of the Russian Mars 96 mission.
