Marci (crater)

Marci is a small, mostly unremarkable lunar crater on the far side of the Moon. It is located about one crater diameter to the west of the prominent crater Jackson. To the northwest of Marci is the larger crater Fitzgerald.

This is a roughly circular, bowl-shaped feature with slight outward bulges in the rim to the north and south. The inner walls are generally simple slopes the run down to the interior floor. This floor is about half the diameter of the crater. Marci lies within the bright ray system that surrounds Jackson.

Satellite craters

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Marci.

Mars Reconnaissance Orbiter

Mars Reconnaissance Orbiter (MRO) is a multipurpose spacecraft designed to conduct reconnaissance and exploration of Mars from orbit. The US$720 million spacecraft was built by Lockheed Martin under the supervision of the Jet Propulsion Laboratory (JPL). The mission is managed by the California Institute of Technology, at the JPL, in La Cañada Flintridge, California, for the NASA Science Mission Directorate, Washington, D.C. It was launched August 12, 2005, and attained Martian orbit on March 10, 2006. In November 2006, after five months of aerobraking, it entered its final science orbit and began its primary science phase. As MRO entered orbit, it joined five other active spacecraft which were either in orbit or on the planet's surface: Mars Global Surveyor, Mars Express, 2001 Mars Odyssey, and the two Mars Exploration Rovers (Spirit and Opportunity); at the time, this set a record for the most operational spacecraft in the immediate vicinity of Mars. Mars Global Surveyor and the Spirit rover have since ceased to function; the remainder remain operational as of July 2015.
