Communication with Voyager 2, NASA’s planetary probe, which has been on a mission for regarding 50 years, has been cut off. NASA announced on the 28th through its official channel that all communication with Voyager 2, which is currently flying in interstellar space regarding 19.9 billion km away from Earth, has been suspended. Communications recovery was expected in October. According to NASA’s Jet Propulsion Laboratory (JPL), ‘Voyager 2’ accidentally sent an erroneous command on the 21st, causing the communication antenna to turn in a different direction from the Earth. Due to this influence, communication between the ‘Deep Space Network’ antenna operated by NASA and ‘Voyager 2’ was cut off. Voyager 2 as it passed Saturn in 1981 <사진=NASA 공식 홈페이지>
A JPL official said, “‘Voyager 2’ has a program that adjusts its posture every year to turn its antenna toward the Earth,” and “As the next correction is made on October 15, communication with the Earth will resume at this time.” . Voyager 2 was launched in 1977 to explore the solar system planets Jupiter, Saturn, Uranus and Neptune. ‘Voyager 1’ and twin probes have been active for 46 years until this year.

Voyager 1, which was launched in the same year, is currently flying regarding 24 billion kilometers from Earth. The two probes, which have already crossed the heliosphere, have reached interstellar space and are investigating unknown territories. For reference, this is not the first time that ‘Voyager’ 1 and 2 have had system errors. In the case of Voyager 1, there was a problem with the attitude control system that accurately adjusts the high-gain antenna required for communication with the Earth in 2022. At that time, ‘Voyager 1’ also recovered errors through an automatic correction program. Reporter Jeong Ian [email protected] ⇨ Go to Sputnik Naver Post ⇨ Go to Sputnik YouTube channel
