Asteroid Earth Impact? ‘June 30 Asteroid Day’ Live Broadcast on YouTube – Sciencetimes

In commemoration of ‘World Asteroid Day’ (June 30 every year), the National Gwacheon Science Museum is hosting an online science talk about asteroids, ‘Why? It was announced on the 27th that ‘Asteroid’ will be broadcast live on YouTube.

In the broadcast, Dr. Myung-Jin Kim of the Space Hazard Monitoring Center of the Korea Astronomy and Space Science Institute will give a lecture on three topics focusing on asteroids, and the order of audience participation will be provided.

Asteroid Day began on June 30, 2015 when scientists, astronauts, and artists from around the world signed a declaration informing the international community about the danger of asteroid impact and requesting the international community to respond. The United Nations officially designated June 30 the following year as International Asteroid Day.

June 30 is the day in 1908 that an asteroid with a diameter of 50 meters fell and exploded in the sky in Tunguska, Russia, causing great damage, such as burning forests with a radius of several hundred kilometers.

Every year, before and after Asteroid Day, various commemorative events are held at science centers and universities around the world to recognize the threat of asteroid impact and discuss joint defense measures.

Asteroids, which did not become planets in the early stages of the formation of the solar system and are called debris floating in outer space, are being actively explored in space around the world.

In December of last year, Japan’s Hayabusa 2 brought samples taken from the asteroid ‘Ryugu’ to Earth, and in May, NASA’s Osiris-Rex probe returned to Earth with samples of the near-Earth asteroid ‘Benu’. got on the road

In Korea, too, the Korea Astronomy and Space Science Institute is conducting a conceptual design to directly explore the Earth-threatening asteroid ‘Apophis’ passing by the Earth in 2029.

In his lecture, Dr. Kim Myung-jin talks about the scientific and commercial value of asteroid exploration, research on asteroids that are a threat to the human civilization community, and Korea’s asteroid exploration plan.
