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.

Comba am Prescott-Observatorium (IAU-Code 684) in Prescott, Arizona entdeckt wurde. Der Asteroid wurde nach dem ungarischen Mathematiker Marcel Riesz (1886–1969) benannt, der auf dem Gebiet der Fraktionalen Infinitesimalrechnung arbeitete und wie sein älterer Bruder Frigyes Riesz wesentliche Beiträge zur Funktionalanalysis geleistet hat. Die Benennung des Asteroiden erfolgte am 27. April 2002.
