I figured I'd check the stats myself. This is based on images downlinked, excluding multiple versions, and doesn't rely on the image browsing sites, but I cannot vouch for absolute completeness. I also am ignoring thumbnails and looking only at the EFF, ESF, and EDN types. I see a total of 120,604 Spirit images, 124,728 Opportunity images, for 245k images. That adds up to 261 Gbits (2.5% of which is from thumbnails and engineering/calibration data) as downlinked. Image number by camera (A/B) is: Pancam 78,929/80,972; MI 5,824/5,996; engineering--the rest. Among Pancam, 8,806/13,298 are of the Sun or sky; 16,482/15,739 are of the cal targets (aka sundial). Those two categories add up to <4% of total Pancam bits downlinked. The rovers have taken over 300,000 images (147,166/160,573); the difference between these numbers and the first set comes from images taken but deleted on board (e.g., some empty dust devil movies) or taken only in thumbnail form (or maybe some missed in my count?). By type, Pancam images are mostly EFF or ESF (like Sun and sundial), MI are almost all EFF, and engineering images are mostly EFF or EDN (like autonav).
* The numbers are as of mid-day (UTC) 15 Sept. 2009 (probably sols 2026/2006 PM downlink). [edit: fixed Mbits to Gbits. What's 3 orders of magnitude among friends...] |
