Before being put into ‘sleep’ mode, equipment from India’s Chandrayaan-3 mission Collecting valuable information about the moon…one of the discoveries announced by the Indian Space Research Organization (ISRO) Movements were detected under the moon’s surface. This may be the first seismic data recorded on Earth’s natural satellite since the 1970s.

Natural event

According to the researchers, the movements were recorded by the Lunar Seismic Activity (ILSA) instrument on board the Vikram lander. In addition to the sounds made by Pragyan’s robotic vehicle, The tool captured what would have been a natural event, such as a seismic shock or collision.

“The main objective of ILSA is to measure ground vibrations caused by natural earthquakes, impacts and man-made events. The vibrations recorded during the rover’s navigation on August 25, 2023 are shown in the figure,” ISRO scientists said in a statement. “In addition to, A seemingly natural event also appears, They added: “It was recorded on August 26, 2023. The origin of this event is currently being investigated.”

Tremors detected on the Moon by seismometers carried by NASA’s Apollo program, It provided valuable data on the formation of the Moon. Interpreting this information (captured between 1969 and 1977), scientists suggested that the Moon has an inner core about 500 kilometers in diameter, which is much less dense than Earth’s core. New data obtained by the Indian mission could help scientists better understand what is happening beneath the surface of the moon.
