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(15874) 1996 TL66是一顆外海王星天體,是由大衛·朱維特(David C. Jewitt)、珍妮·劉(Jane X. Luu)與華裔美籍的三位天文學家所共同發現的,也是第一顆黃道離散天體。雖然比較早被發現,但是卻比較晚被分類為黃道離散天體。經過光學與熱量聯合觀測後,它的直徑估計約為630公里。
