Jupiter orbiter in 'safe mode' after software issue 
NASA's Juno spacecraft went into safe mode just before its latest Jupiter flyby, making it unable to collect any scientific data. NASA said this was caused by a possible software issue, prompting Juno's onboard computer to initiate a 'safe' reboot, turning off instruments and some non-critical spacecraft components. Since July 4, Juno has made a Jupiter flyby every 53 days.
