NASA’s Juno spacecraft entered safe mode twice during its April 4 flyby of Jupiter, suspending science operations after detecting anomalies.

The spacecraft, which is solar-powered, rebooted and maintained communication as designed. Initial signs suggest intense radiation near Jupiter triggered the events.

Juno has now entered safe mode four times since 2016 but has recovered fully each time, Phys.org has reported.

The mission team is analyzing data and preparing for Juno’s next close pass on May 7, which includes a flyby of Jupiter’s moon Io.
