Hello,
I use Hiview from the university of Arizona.
Hiview is a data explorer and image viewing application impporting
JP2000 image format. I use it for Mars Planetology.
But, you need full of computer's capacity to do this, (ie: 32g/memory ddr3 at 2000htz); The image zooming from NASA is about 150 000 pixels.
Also you find it the incredible Image from geological map of Mars.
