Summary
edit
| Description | Viking 1 lander image of Chryse Planitia with trenches made by the sampler arm. |
| Date | 2009-01-29; original photos were taken 1976-08-20. |
| Source | Own work based on images in the NASA Viking image archive |
| Author | "Roel van der Hoorn (Van der Hoorn)" |
| Permission (Reusing this file) |
I used the original 12f203.blu, 12f203.grn and 12f203.red images from the NASA Viking image archive, converted them to .png, manually removed the noise and merged them into one image (almost matching true color; see here for the channel mixing process). Except for the conversion, this was done in Adobe Photoshop CS2. The original file by NASA is in the public domain, and so is this new one. |
| Other versions | I created this image as a replacement for the image Chryse Planitia.jpg. The quality of this file was not very high. Using the original pictures from the Lander archive resulted in a higher quality image. |
