- Plus two "forgotten" Hasselblad photographs of Tsiolkovskiy: AS12-47-6869 and AS12-47-6870. These two photographs are also online as King-Size Hi-Res; in Kipp Teague's PROJECT APOLLO ARCHIVE (Full Hasselblad Magazines).
- AS15-91-12383 which is an extraordinary oblique Hasselblad of Tsiolkovskiy's central peak, looking like an "isle of chalk, surrounded by a sea of asphalt", was included on page 252 of the article TO THE MOUNTAINS OF THE MOON by Kenneth F. Weaver (NATIONAL GEOGRAPHIC, February 1972). Research: Danny Caes.
- AS08-14-2450, which is one of six oblique Hasselblads of Tsiolkovskiy's central peak and immediate environs, shows a remarkable greenish coloration. This greenish/ bluish coloration is something which is noticeable on almost all of Apollo 8's color-Hasselblads of the moon. - DannyCaes Nov 22, 2007
- Central peak composition: A, GNTA1, GNTA2, AT (Tompkins & Pieters, 1999)
- Exterior impact melt deposits most extensive to SE, max of ~50 km beyond rim. Most extensive ejecta, rays and secondary craters to the SSE, with max wall slumping on SE side of crater, and topographically lowest rim crest to W (Hawke and Head, 1977).
- Tsiolkovsky was formed by an oblique impact Craddock and Greely, 1988 with the projectile coming from the NNW; the presence of previous Fermi crater determined a lower west rim
- Crater counting gives age of 3.51 billion years for mare on crater floor (Tyrie, A. (1988) Earth, Moon & Planets 42, #3, 245-264.
- On the moon's globe, Tsiolkovskiy is almost the exact antipode of Aristarchus. Strange as it is, nearside crater Aristarchus has the most high-albedo inner slopes and floor of all the pronounced craters on the moon's surface, while farside crater Tsiolkovskij has the most low-albedo floor of all (or so it seems).

- TSI = 35, CPI = 20, FI = 25; MI =80 Smith and Hartnell, 1973
- Tsiolkovsky was a Constellation Program Region of Interest.

- Note: West rim is much lower than East rim. Summit of central peak is high point on a T-shaped ridge.
- Crater depth: Measurements on 4 axes separated by 45 degrees.
- Zero reference level = Moon average radius.
- Average floor level (average of lowest levels on 4 axes) = -1831m
- Average rim height (average of 8 rim data points) = +2970m
- Average crater depth (average rim height to average floor level) = 4.80km
- Deepest point on crater floor(from zero reference level) = -1877m
- Max. crater depth (highest point on rim to deepest point on crater floor) = 5.91km
Central Peak Height(above average floor level) = 2.76km
- Named for Konstantin Eduardovich Tsiolkovsky (September 17, 1857 – September 19, 1935), an Imperial Russian and Soviet rocket scientist, physicist and pioneer of astronautic theory. Image (possibly a drawing) below is of Tsiolkovskiy.
