Asteroid Day is held annually on 30 June, the same day that the biggest asteroid impact in the Earth’s recent history occurred in Tunguska in Siberia in 1908. POST Philately is issuing a series of three special stamps over three years; the first motif this year depicts “Defense”. In 2023, a motif on the theme of “Discovery” will be issued, while for 2024, the year in which “Asteroid Day” will celebrate its 10th anniversary, the subject of the stamp will be “Space Resources” (mining and utilisation of natural resources in space).
