  We present current and future activities regarding lunar impact flash and NEO
observations and satellite tracking from Kryoneri Observatory. In particular,
we present results from the ESA-funded NELIOTA program, which has been
monitoring the Moon for impact flashes since early 2017. Using the 1.2 m
Kryoneri telescope, which is equipped with two high frame-rate cameras
recording simultaneously in two optical bands, NELIOTA has recorded over 170
validated lunar impact flashes, while another ~90 have been characterized as
suspected. We present statistical results concerning the sizes, the masses and
the appearance frequency of the meteoroids in the vicinity of the Earth, as
well as the temperatures developed during the impacts. Moreover, we present the
capabilities of the Kryoneri telescope as a sensor for satellite tracking and
the future plans regarding the provision of high-quality services for both the
Planetary Defense activities of ESA (S2P/PDO) and the European Union's Space
Surveillance and Tracking programme (EU/SST).
