NASA’s Juno ship unexpectedly entered a state of caution. It was when he was making his approach to Jupiter number 71, probably when flying his radiation belts. The Juno ship worries in Jupiter, but it is believed that it can return to its normal cycle.
The ship is driven by solar energy. He entered safely twice in 45 minutes on April 4 while Jupiter flew over. The safe mode is a state of precaution to which a spacecraft enters when it detects an anomaly. Non -essential functions are suspended. The ship focuses on essential tasks such as communication and energy management. Upon entering safe mode, Juno’s scientific instruments went out, as planned, during the rest of the overflow.
Safe mode
The mission operations team restored high -speed data transmission with Juno. The spacecraft is currently making flight software diagnoses. The team will work in the next few days to transmit to the Earth the scientific and engineering data collected before and after the events safely.
During both events, the spacecraft worked exactly as planned. He restarted his computer, deactivated non -essential functions and pointed his antenna to the Earth to communicate, reports NASA.
Of all the planets of our solar system, Jupiter houses the most hostile environment. They are the radiation belts closest to the planet the most intense. The first indications suggest that the two safe events occurred while the spacecraft fly over these belts. How to prevent high -energy particles from impacting sensitive electronic components? Juno has a titanium radiation vault.
Previous events
The Juno ship worries in Jupiter, but before he already responded positively. Including these events, Juno entered into safe mode induced by the spacecraft four times. He did it since his arrival in Jupiter in July 2016. First, in 2016 during his second orbit, and then in 2022 during his orbit 39. In all four cases, the spacecraft worked as expected and recovered its maximum capacity. Juno was launched to space on August 5, 2011.
The next periodic approach of Juno will happen on May 7. It will include an overflow of the Jovian moon ío at a distance of approximately 89,000 kilometers.
