The Korea Aerospace Research Institute confirmed that the Russian Venus probe 'Cosmos 482 lander' crashed near the South Pacific, west of southern Chile, around 2:30 p.m. on the 10th.
The Cosmos 482 lander is a former Soviet Venus probe descent module launched in March 1972, which became isolated in Earth's orbit after the mother ship's engine shut down prematurely and re-entered this time. The lander's weight is estimated to be 485 kg, with a diameter of 1 m.
The United States Space Command's Combined Space Operations Center (CSpOC) released a crash analysis message at 7:16 p.m. the same day, explaining that the lander re-entered Earth's atmosphere at around 2:20 p.m. to 2:44 p.m. near the South Pacific.
The Korea Astronomy and Space Science Institute, which monitors space hazards, presented a crash prediction time between 2:13 p.m. and 3:13 p.m. based on an analysis at 8 a.m., seven hours before the crash.
The Korea Aerospace Research Institute assessed that this prediction was more proactive and precise than the CSpOC's analysis two hours before the crash, which estimated the time between 1:33 p.m. and 3:31 p.m.
Earlier, the Astronomy Institute had forecasted that the lander's crash point would be in the afternoon on the 10th and predicted that the trajectory would not include the Korean Peninsula.
