Just how good is the HRSC Imagery vs HiRISE imagery?
HRSC camera (Left), on Mars Express, launched in 2003, captures 12.5 meters/pixel
HiRISE camera (Right), on Mars Reconnaissance Orbiter, launched in 2005, captures 50 centimeter/pixel.
Lets compare these two images using JMars (http://jmars.asu.edu/)
HiRISE image: ESP_016881_1805_COLOR
HRSC image: H1965_0000_ND3
Lets take a look around 3.459E 0.4127N
Now lets look with the HiRISE footprint overlaid
Lets get even closer
