Full data on this image has now been released via the THEMIS Data Releases website.
From crater exteriors we move to looking at crater ejecta
with today’s image. Note the radial “spokes” on the top of the
ejecta surrounding the crater. These surface features are formed
during the ballistic emplacement of the ejecta and other materials
being thrown out of the crater by the force of the impact.
[Source: ASU THEMIS Science Team]Note: this THEMIS visual image has not been radiometrically nor geometrically calibrated for this preliminary release. An empirical correction has been performed to remove instrumental effects. A linear shift has been applied in the cross-track and down-track direction to approximate spacecraft and planetary motion. Fully calibrated and geometrically projected images will be released through the Planetary Data System in accordance with Project policies at a later time.
