Sample of PDS Science - June 1999

Pathfinder science data continues to be processed and made available through the Planetary Data System.

See the Planetary Photojournal for a Complete Listing of PDS Science Updates and High Resolution Images


 PIA01546.jpg

True Color of Mars - Pathfinder Sol 10 at noon Catalog #: PIA01546

Original Caption Released with Image:
The true color of Mars based upon three filters with the sky set to a luminance of 60. The color of the Pathfinder landing
site is yellowish brown with only subtle variations. These colors are identical to the measured colors of the Viking
landing sites reported by Huck et al. [1977]. This image was taken near local noon on Sol 10. A description of the
techniques used to generate this color image from IMP data can be found in Maki et al., 1999. Note: a calibrated
output device is required accurately reproduce the correct colors.


PIA01547.jpg

True Color of Mars - Pathfinder Sol 24 at 4 PM Catalog #: PIA01547

Original Caption Released with Image:
The brownish gray sky as it would be seen by an observer on Mars in this four-frame, true color mosaic taken on sol 24
(at approximately 1610 LST). The twin peaks can be seen on the horizon. The sky near the sun is a pale blue color.
Azimuth extent is 60° and elevation extent is approximately 12° degrees. A description of the techniques used to
generate this color image from IMP data can be found in Maki et al., 1999 (see full reference in Image Note). Note: a
calibrated output device is required accurately reproduce the correct colors.


PIA01551.jpg

Newly Deployed Soujourner Rover Catalog #: PIA01551

Original Caption Released with Image:
This 8-image mosaic was acquired during the late afternoon (near 5pm LST, note the long shadows) on Sol 2 as part of
the predeploy 'insurance panorama' and shows the newly deployed rover sitting on the Martian surface. This color
image was generated from images acquired at 530,600, and 750 nm. The insurance panorama was designed as
'insurance' against camera failure upon deployment. Had the camera failed, the losslessly-compressed, multispectral
insurance panorama would have been the main source of image data from the IMP.

However, the camera deployment was successful, leaving the insurance panorama to be downlinked to Earth several
weeks later. Ironically enough, the insurance panorama contains some of the best quality image data because of the
lossless data compression and relatively dust-free state of the camera and associated lander/rover hardware on Sol 2.
