1045 Michela is a main-belt asteroid that orbits the Sun. It was discovered by George Van Biesbroeck at Yerkes Observatory on November 19, 1924. The object has a diameter of 6.104 kilometers and an albedo of 0.328. Its rotation period is 2.701 hours, and it possesses an absolute magnitude of 13.04.
The asteroid’s orbital parameters include a semi-major axis of 2.358714662530806 astronomical units and an orbital period of 1323.157482294625 days. Its orbit has an eccentricity of 0.16 and an inclination of 0.26480 degrees. The periapsis is located at 1.985297587044349 astronomical units, while the apoapsis is at 2.736 astronomical units. Additional orbital elements include a mean anomaly of 301.6894445921955, a longitude of ascending node of 267.68067, and an argument of periapsis of 167.5143058310496.

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.
