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.

小行星19308((19308) 1996 TO66)是一个海王星外天体,1996年由乍德·特魯希略、大卫·朱维特,以及刘丽杏三名天文学家发现。在小行星20000发现前,小行星19308是柯伊伯带已发现天体中第二大的,直径推测约200千米或约529千米,但一定小于902千米。小行星19308是妊神星族碰撞家族的一员,物理组成和妊神星相似,拒信起源于过去两颗天体碰撞时喷出的地幔。
