The project included further measurements, which concluded that 75–80% of the meteoroids had a mass of less than 200 grams (0.44 lb) and a radius under 3 centimetres (1.2 in), while the craters produced by the collisions have a size of 1.5 to 3 meters (4.9 to 9.8 ft).
Moreover, for the multiframe lunar impact flashes in both pass bands, it was found that there is no unique behaviour after the observed maximum temperature, meaning that most of them exhibit a drop off after the peak.
[2] As for satellites in lunar orbit, CubeSats and Starlink sized spacecraft have extremely low probabilities of being hit, on the order of 10−7 for a 5 years mission duration.
It should be clarified that these numbers were calculated only with the asteroids that have the physical properties that allowed them to be detected by the NELIOTA project, so objects like micrometeorites were not taken into consideration.
[2] The NELIOTA project was funded by the European Space Agency with a special contract from 2015 to 2021, which included the upgrade of the 1.23 m telescope at the Kryoneri Observatory in 2016.
[7] This contract ended in January 2021 and the European Space Agency continued the funding in August 2021 via its Consolidating Activities Regarding Moon, Earth and NEOs (CARMEN) project, until July 2023.
