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
254 Augusta is a main-belt asteroid, discovered on 31 March 1886 by astronomer Johann Palisa at Vienna Observatory, Austria. The stony S-type asteroid measures about 12 kilometers in diameter. It is the first-numbered member of the Augusta family, after which the small Asteroid family and subgroup of the main-belt has been named. Augusta was named after the German–Austrian writer Auguste von Littrow (1819–1890), widow of astronomer Carl Ludwig von Littrow, who was a former director of the Vienna Observatory.
