Pathfinder on Mars

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

298 Baptistina is an asteroid orbiting in the asteroid belt. It is the namesake of the Baptistina family. It was discovered on 9 September 1890 by Auguste Charlois of Nice. The source of its name is unknown. It measures about 13–30 km (8.1–18.6 mi) in diameter. Although it has an orbit similar to the Flora family asteroids, it was once considered a possible source of the impactor that caused the extinction of the dinosaurs, a possibility ruled out by the Wide-field Infrared Survey Explorer (WISE) in 2011.
