No 2022. gada ekonomisko sadārdzinājumu dēļ, Meteorītu muzejs ir spiests ieviest minimālo sensa apmeklējuma maksu 10,00€ apmērā! Cenšoties saglabāt plašu mūsu zinātnisko resursu pieejamību, esam priecīgi arī turpmāk 2022. gadā nodrošināt ģimenes un vairāku apmeklētāju grupas gadījumā iepriekšējās cenu atlaides!
