Was the Pathfinder solar-powered?
The Pathfinder was a lightweight, solar-powered, remotely piloted flying wing aircraft that demonstrated the technology of applying solar power for long-duration, high-altitude flight.
How was the pathfinder powered?
Pathfinder was powered by eight electric motors — later reduced to six — which were first powered by batteries. It had a wing span of 98.4 feet (30.0 m). Two underwing pods contain the landing gear, batteries, triple-redundant instrumentation system, and dual-redundant flight control computers.
How is the pathfinder able to fly into the earth’s stratosphere for long periods of time?
Solar arrays covering most of the upper wing surface provide power for the aircraft’s electric motors, avionics, communications and other electronic systems. Pathfinder also has a backup battery system that can provide power for between two and five hours to allow limited-duration flight after dark.
Can planes be powered by solar energy?
Sunrise, the world’s first solar-powered airplane, took to the skies in 1974. Solar-powered airplanes have come a long way since then. Solar-powered airplanes, as opposed to ordinary airplanes, capture solar irradiance and transform it into electrical energy using photovoltaic panels.
What happened to NASA Pathfinder?
End of mission Communication failed after October 7, with a final data transmission received from Pathfinder at 10:23 UTC on September 27, 1997. Mission managers tried to restore full communications during the following five months, but the mission was terminated on March 10, 1998.
Is Pathfinder a NASA?
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.
Is Mars Pathfinder still working?
How long did it take Pathfinder to reach Mars?
seven months
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.

How long did it take Pathfinder to get to Mars?
How does the solar power work on the Pathfinder?
The solar arrays provide power for the aircraft’s electric motors, avionics, communications and other electronic systems. Pathfinder also had a backup battery system that can provide power for between two and five hours to allow limited-duration flight after dark.
What is the NASA Pathfinder?
At the NASA Dryden Flight Research Center at Edwards, CA, imagination has become reality, and that reality is the Pathfinder solar-powered, remotely piloted aircraft.
What is a solar powered aircraft?
An aircraft that could stay aloft all day, powered only by sunlight. An aircraft that is no more than a flying wing, able to maneuver without rudders, ailerons, tails, or other control surfaces typical of conventional aircraft. An aircraft that flies without an onboard human pilot, but instead is controlled remotely from a ground station.
What has Pathfinder flight tested so far?
Thus far, Pathfinder has flight tested two new scientific instruments, a high spectral resolution Digital Array Scanned Interferometer (DASI) and a high spatial resolution Airborne Real-Time Imaging System (ARTIS), both developed at Ames. These flights were conducted at altitudes between 22,000 and 49,000 feet in 1997.
