Pathfinder on Mars
2026-07-04
On July 4th, 1997, using its own array of fireworks, a parachute, and a cocoon of airbags, the Mars Pathfinder spacecraft bounced like a giant beach ball at least 15 times before it came to rest on the surface of Mars at 10:07 AM Pacific Daylight Time. After its then novel airbag-assisted landing sequence was completed, Pathfinder transmitted this color mosaic to mission operators on Earth. In the scene from another world, the Mars Sojourner robot rover is visible in the foreground, crouched on top of the unfolded Pathfinder. About the size of a large house cat, the six-wheeled, solar-powered Sojourner became the first successful Martian rover. Surrounding Pathfinder are deflated airbags and the rock-strewn terrain of the Ares Vallis floodplain. In the distance Martian hills appear against a dusty brownish sky. The Pathfinder lander was subsequently renamed the Carl Sagan Memorial Station.

Encyclopedic overview
798 Ruth is a minor planet orbiting the Sun that was discovered by the German astronomer Max Wolf on 21 November 1914. It may have been named after the biblical character Ruth. This main belt asteroid has an orbital period of 5.23 years and is orbiting at a distance of 3.0 AU from the Sun with an eccentricity (ovalness) of 0.036. The orbital plane is tilted by 9.2° from the plane of the ecliptic.
This is a member of the dynamic Eos family of asteroids that most likely formed as the result of a collisional breakup of a parent body. It is an M-type (metallic) asteroid that displays a significant component of the mineral olivine in its spectrum. 798 Ruth spans 43.19±2.9 km and rotates on its axis once every 8.55 h.
