Database Statistics
Date tabulated: 22 Aug. 2019
Number of missions in catalog: 223

UNIQUE RECORDS (Images Table and Frames Table) This total includes both photos that have images in our database and those that do not.
Total number of photographs taken by astronauts: 3,750,480

ALL IMAGES (Images Table) This total is based on counts of unique photo IDs (mission-roll-frame combinations) in the IMAGES table. Note that the IMAGES table can contain multiple images per photo ID. So the count below is of all of these per photo ID just once. This total includes only those photos that have images in our database.
Total number of images taken by astronauts: 3,663,246
