In 1966, the Soviet Union made history when its Luna 9 mission placed the first object built by humans on the surface of the Moon, broadcasting imagery back to Earth following its successful soft landing.<\/p>\n

Despite the safe touchdown of Luna 9\u2019s lander capsule, some questions have lingered about the Soviet spacecraft\u2019s<\/a> historic mission: namely, its final resting place, which remains unknown.<\/p>\n

That could be about to change, however. With the help of artificial intelligence<\/a>, an international team of researchers has identified several locations on the Moon they believe could finally reveal the location of the \u201clost\u201d spacecraft.<\/p>\n

Among these possible landing sites, one location near lunar N latitude 7.02907\u00b0 and longitude -64.32867\u00b0 is particularly promising, revealing a large crater with a bright area near one of its edges, which is surrounded by several other impact features, which researchers say may represent \u201cpotential spacecraft hardware objects\u201d left behind by the 1966 mission. The team\u2019s findings were published in npj Space Exploration. <\/p>\n

A Cold War-Era Mystery <\/p>\n

Luna 9\u2019s historic 1966 lunar landing marked the first instance where a piece of human-built hardware had been placed on the surface of a celestial body beyond Earth<\/a>.<\/p>\n

By modern standards, the Luna 9 landing was hectic, with the spacecraft tumbling along the lunar surface on built-in shock absorbers before finally settling in its final resting place, where it remained operational for only a matter of days. During that roughly 36-hour window, the spacecraft successfully transmitted important information back to Earth, setting the pace for space exploration in the coming years that would eventually bring the first humans to the Moon.<\/p>\n

Despite high-resolution imagery of the lunar surface that has been readily available since the deployment of NASA\u2019s Lunar Reconnaissance Orbiter<\/a> Camera (LROC) in 2009, no confirmed detection of the Luna 9 landing site has been made. One reason for this involves the original calculations made about the spacecraft\u2019s 1966 landing, which were far from exact. By some estimates, the location of Luna 9 could be as much as several dozen kilometers away from the general area where the spacecraft is believed to have landed.<\/p>\n

Rediscovering a Lost Soviet Spacecraft<\/p>\n

In recent research led by Lewis Pinault at University College London, along with colleagues Hajime Yano and Ian Crawford, artificial intelligence was used to narrow down possible locations of the \u201cmissing\u201d Luna 9 lander.<\/p>\n

Enter the intriguingly-named \u201cYou-Only-Look-Once \u2013 Extraterrestrial Artefact\u201d (YOLO-ETA), which the researchers describe as a lightweight computer imaging system adapted from TinyYOLOv2, an architecture designed to detect human-built objects, such as spacecraft, in high-resolution LROC images.<\/p>\n

Training YOLO-ETA using the well-known landing sites<\/a> of NASA\u2019s Apollo missions<\/a>, the team says they reached an overall confidence score for possible spacecraft detections of around 80%, which enabled them to then train the imaging system on the general region where Luna was believed to have touched down.<\/p>\n

\u201cApplying the model to a 5\u2009\u00d7\u20095\u2009km region surrounding the historically uncertain Luna 9 landing area yielded several high-confidence detections of artificial objects near 7.03\u00b0 N, \u201364.33\u00b0 E,\u201d the researchers report. \u201cTopographic analysis indicates that the candidate site\u2019s horizon geometry is potentially consistent with Luna 9 surface panoramas.\u201d<\/p>\n

Notably, the team was able to determine a primary impact feature, in which a luminous area can be discerned, which they believe may be the final landing place of Luna 9. In the surrounding area, several additional impacts or other features can also be seen, which may be secondary \u201chardware objects\u201d\u2014essentially debris left over from the 1966 mission.<\/p>\n

The locations Pinault and his colleagues identified appear to be consistent with the kinds of features associated with known spacecraft landings and the disturbances they have caused to the Moon\u2019s surface during past lunar missions.<\/p>\n

\u201cThese findings identify promising locations for follow-up imaging and demonstrate that compact, edge-deployable machine-learning models can support future orbital surveys of lunar artefacts and surface assets,\u201d the team writes in their paper.<\/p>\n

Going forward, Pinault and colleagues believe they YOLO-ETA may be useful \u201cin detecting known lunar artefacts and can assist in the search for undetected historical spacecraft.\u201d Such capabilities, they argue, are of great importance as they will help to support various space agencies\u2019 ability to monitor the lunar surface in the coming years, especially as exploration<\/a> of Earth\u2019s natural satellite is expected to increase<\/a>.<\/p>\n

For now, the team\u2019s findings remain to be confirmed, though they believe such an opportunity will likely occur as soon as next month, when India\u2019s Chandrayaan-2 orbiter passes over the region. If YOLO-ETA\u2019s assessment turns out to be correct, it will finally bring a resolution to one of the great unanswered questions of Cold War-era space exploration.<\/p>\n
