Hills Still a Distant Goal for Spirit
Hills Still a Distant Goal for Spirit

NASA's Mars Exploration Rover Spirit took this grey-scale panoramic camera image on sol 100, April 15, 2004. It captures Spirit's future destination at the highlands informally named "Columbia Hills". In this image, the hills are approximately 2.4 kilometers (1.5 miles) to the southeast. Scientists believe the hills may consist of different and potentially older rock units than the basalts that Spirit has observed so far.

Daisy Found on 'Route 66'
Daisy Found on 'Route 66'

This composite image from the panoramic camera on NASA's Mars Exploration Rover Spirit gives an approximately true-color rendering of a daisy-like pattern of brushed circles that Spirit produced on a rock called "Route 66." Spirit used the rock abrasion tool to complete this 6-position "RAT daisy" on sol 99. It took this image on sol 100, April 15, 2004.

The purpose for these large brushings is to create a large enough patch of treated surface area for the miniature thermal emission spectrometer to analyze. Scientists had previously conducted a brushing like this one on the rock "Mazatzal." The brushed area of Route 66 looks very different from the brushed area of Mazatzal, leading scientists to think that the rocks � although both light in tone � actually have different coating types.
