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
224 Oceana is an asteroid from the asteroid belt. It was discovered by Austrian astronomer Johann Palisa on 30 March 1882, in Vienna. It was named after the Pacific Ocean. Based upon its spectrum, it is classified as an M-type asteroid, but is not metallic.
A light curve generated from photometric observations of this asteroid at Pulkovo Observatory show a rotation period of 9.401 ± 0.001 hours and a brightness variation of 0.09 ± 0.01 in magnitude.
