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
730 Athanasia (prov. designation: A912 GG or 1912 OK) is a background asteroid from the inner regions of the asteroid belt, approximately 4.5 kilometers (2.8 miles) in diameter. It was discovered by Austrian astronomer Johann Palisa at the Vienna Observatory on 10 April 1912. The presumed stony S-type asteroid has a rotation period of 5.7 hours and is likely very elongated in shape. It was named Athanasia, the Greek word for "immortality".
