PIA14394: Taking the Measure of Impact Craters on Mercury


Taking the Measure of Impact Craters on Mercury

Caption:

An example complex crater on Mercury, ~ 55 km in diameter and centered near 63.5°N, -139°E, that has been imaged by MDIS (left) and profiled by MLA (right). A slightly larger complex crater lies along the MLA profile to the south. To read more about about how craters on Mercury are measured, visit the MESSENGER Science Highlight article .

Date Presented: July 7, 2011, in a MESSENGER Science Highlight article.

Background Info:

The MESSENGER spacecraft is the first ever to orbit the planet Mercury, and the spacecraft's seven scientific instruments and radio science investigation are unraveling the history and evolution of the Solar System's innermost planet. Visit the Why Mercury? section of this website to learn more about the key science questions that the MESSENGER mission is addressing.

These images are from MESSENGER, a NASA Discovery mission to conduct the first orbital study of the innermost planet, Mercury. For information regarding the use of images, see the MESSENGER image use policy .
