The first network (M-FM) received scattered radio signals from FM transmitters. The second network (M-GRAVES) received scattered radio signals from the GRAVES radar in France. Basically, these networks observe signals reflected by meteor trails, not meteoroids. In January 2022, the M-FM network included 5 working stations located in Mykolaiv, Rivne, Glukhiv. In January 2022, these stations registered 23063 meteors. The M-GRAVES network included 3 stations. The results of observations of both networks in January 2022 are presented on the RMOB (Radio Meteor Observing Bulletin) website. According to the results of observations with a complex of optical meteor telescopes, 195 meteor registrations were obtained. Light curves in two instrumental photometric bands for 2 meteor phenomena were obtained. In September 2022, the final stage of space mission, named Double Asteroid Redirection Test was conducted. This is the first ever project to change the trajectory of asteroids. The unmanned spacecraft was directed to the double near-Earth asteroid system 65803 (Didymos) for a collision with its satellite Dimorph. In October 2022, a near-Earth asteroid 65803 (Didymos) was observed. 41 topocentric positions of this asteroid have been calculated. The positions were sent to the minor planet center database of the International Astronomical Union (IAU) and published in the IAU circular. The mean values of the residual differences (О - С) in relation to the HORIZONS ephemeris (JPL NASA, USA) are (-0.7 ± 0.3)" and (0.0 ± 0.3)" in right ascension and declination, respectively.
