Custom illustration to "Faded Flags on the Moon," entry to Dr. Paul Spudis' Smithsonian Air & Space blog "The One & Future Moon," July 20, 2011. The notional scene is an original image from the Apollo 15 expedition in 1971, with a touch of imagination added; how that same scene might look four decades later.

Cracks - not boulders! - abound on the ridge crest of this wrinkle ridge in northeastern Mare Imbrium, not far from Mons Pico. LROC Narrow Angle Camera (NAC) observation M102171046LR, LRO orbit 234, July 14, 2009. Image field of view is 1.7 kilometers [NASA/GSFC/Arizona State University].
LROC Wide Angle Camera monochrome mosaic of northeastern Mare Imbrium. LROC Featured Image July 14, 2011 (asterisk) is located southeast from the are spotlighted two days previously (dot) [NASA/GSFC/Arizona State University].
Impact melt flowed across the primary ejecta of an unnamed Copernican-aged impact crater (46.75°N, 49.81°E). LROC Narrow Angle Camera observation M159631206L & R, LRO orbit 8659, May 10, 2011; source crater toward below, and out of view [NASA/GSFC/Arizona State University].

A distinct lobe of impact melt within the larger melt sheet. How did this feature form? LROC NAC M159631206L,R; source crater toward the bottom of the image [NASA/GSFC/Arizona State University].

0957 UT, 21 July 2011: Atlantis returns to Earth for the final time, bringing an end to the program after more than thirty years, after 200 orbits and 8.5 million km. It was the 25th night landing and 78th landing at KSC only the 133rd landing since 1981. Mission elapsed time 12 days, 18 hours, 28 minutes and 50 seconds. Since April 12, 1981, 355 individuals from 16 countries flew 852 times aboard the shuttle, deploying 180 payloads, including satellites, returned 52 from space and retrieved, repaired and redeployed seven spacecraft. STS-135 was the 33rd and final flight for Atlantis, totaling 307 days in space over 4,848 orbits, traveling 872.3 million kilometers, roughly 48.49 light minutes or 5.8 AU [NASA].
An unprecedented view of the space shuttle Atlantis and the ionization of its re-entry into Earth's atmosphere, "appearing like a bean sprout against clouds and city lights," on its way home, July 21, 2011. Photographed by Expedition 28 from the ISS. Pre-dawn airglow over Earth can be seen in the background [NASA].
A portion of the LROC Global Wide Angle Camera (WAC) mosaic showing the Messier crater region of Mare Fecunditatis, with the LROC Featured Image for July 19, 2011 marked in red. Field of view is about 55 kilometers across [NASA/GSFC/Arizona State University].
Avalanches festoon the layered south interior walls of nearside telescopic landmark Messier A (2.2°S, 46.9°E). LROC Narrow Angle Camera observation M126622485R, LRO orbit 3793, April 23, 2010; solar incidence 25°, from the east - north is up. field of view roughly 625 meters across [NASA/GSFC/Arizona State University].
A slightly different angle on the LROC WAC Global Mosaic and take on Messier and Messier A, with west at the top, reveals to the eye a distinct texture of impact melt on the floor of Messier A and the landslide region on the crater's south interior wall. Through the NAC close-up the impact melt appears to harbor a small pit crater [NASA/GSFC/Arizona State University].
The Messier A crater region as seen through an amateur telescope of moderate power, five nights after New Moon. The unusual oblong shape of Messier, the double impact and westerly direction of the bright rays extending from Messier A seem to point to a very steep and oblique impact [Pete Lawrence].
Scattered among the debris on the impact melt covering the floor of Messier A are more than a few collapse pits, to the northeast of the location of the LROC Featured Image for July 19, 2011 [NASA/GSFC/Arizona State University].
