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.

(46280) Hollar ist ein Asteroid des mittleren Hauptgürtels, der am 21. Mai 2001 vom tschechischen Astronomen Petr Pravec und dem slowakischen Astronomen Peter Kušnirák an der Sternwarte Ondřejov (IAU-Code 557) in Ondřejov u Prahy entdeckt wurde. Der Asteroid gehört zur Eunomia-Familie, einer nach (15) Eunomia benannten Gruppe, zu der vermutlich fünf Prozent der Asteroiden des Hauptgürtels gehören. Die zeitlosen (nichtoskulierenden) Bahnelemente von (46280) Hollar sind fast identisch mit denjenigen von vier kleineren (wenn man von der Absoluten Helligkeit von 14,8, 16,0, 16,1 und 16,6 gegenüber 14,1 ausgeht) Asteroiden: , , und . (46280) Hollar wurde am 10. September 2003 nach dem böhmischen Zeichner und Kupferstecher Wenzel Hollar benannt (1607–1677), der in den Niederlanden und in England arbeitete.
