Database Statistics

Date tabulated: 25 Apr. 2024
Number of missions in catalog: 233

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: 5,140,128

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.
