How did Mars Pathfinder land?
Mars Pathfinder used an innovative method of directly entering the Martian atmosphere, assisted by a parachute to slow its descent through the thin Martian atmosphere and a giant system of airbags to cushion the impact.
How did Pathfinders land softly on Mars?
After traveling 120 million miles in seven months, NASA’s Mars Pathfinder becomes the first U.S. spacecraft to land on Mars in more than two decades. In an ingenious, cost-saving landing procedure, Pathfinder used parachutes to slow its approach to the Martian surface and then deployed airbags to cushion its impact.
What did the Pathfinder discover on Mars?
The airborne dust on Mars was discovered to be magnetic. It is hypothesized that the magnetic mineral is maghemite, a magnetic form of iron oxide. NASA found that the Martian atmosphere gets its yellowish-brown color due to the mixing of fine dust in the lower atmosphere.

Is Mars Pathfinder still working?
End of mission Although the mission was planned to last from a week to a month, the rover operated successfully for almost three months. Communication failed after October 7, with a final data transmission received from Pathfinder at 10:23 UTC on September 27, 1997.
Why did Mars Pathfinder fail?
The problem due to priority inversion caused the spacecraft to reset itself several times after it was landed on Mars on July 4, 1997. Resetting the spacecraft resulted in significant delay in capturing scientific data, which was critical for the mission given that the lifetime of the spacecraft was limited.
