This crescent view of Earth’s Moon in infrared wavelengths comes from a camera test by NASA”s Mars Reconnaissance Orbiter spacecraft on its way to Mars.
The mission’s High Resolution Imaging Science Experiment camera took the image on 8 September 2005, while at a distance of about 10 million kilometers (6 million miles)
from the Moon. The dark feature on the right is Mare Crisium.
The bottom part of the image shows the Moon within the entire view
of the HiRISE camera.
