NASA's Spacecraft, Juno Entered 'safe mode' Last Night When It Approached Jupiter
The Juno spacecraft past NASA entered 'safety mode' on Tuesday nighttime merely 13 hours before its latest flyby of Jupiter. This particular spacecraft has been in orbit since the quaternary of July around Jupiter and because of its elliptical orbit can only get close enough every 53 days to take detailed scientific measurements. Notwithstanding, something recently acquired all of Juno'due south instruments to automatically shut down and hence no data could be collected. NASA is still trying to work out the cause of this strange shutting down.
Something not right. Merely what is it?
During a press conference on Midweek, Scott Bolton, the principle investigator said the shut down may have been the issue of a software problem that caused the spacecraft's calculator to reboot as it "detected a condition that was not expected". Information technology isn't nevertheless very clear what the condition was that caused this unexpected arrangement failure, but NASA seems to be sure that this problem is certainly non due to the high radiation levels and magnetic fields that be around Jupiter. The beginning flyby on the 27th of Baronial revealed that these conditions were much more powerful than were initially expected.
According to Rick Nybakken the Juno project manager, "At the fourth dimension safe mode was entered, the spacecraft was more than than xiii hours from its closest approach to Jupiter. Nosotros were still quite a ways from the planet's more intense radiation belts and magnetic fields." When a NASA space probe enters safe mode, all 'unnecessary subsystems' including scientific instruments and cameras are turned off. After this the spacecraft points itself towards the sun so that it receives every bit much power every bit possible. Juno now awaits farther instructions from NASA, which is currently working to get to the spacecraft to its original working capacity.
Bug and disappointments
Now this isn't the first issue that Juno has had this past week. On Fri, NASA said that they were going to delay changing the spacecraft'south orbit which was initially scheduled to happen during the flyby. This was to be done and then that the spacecraft could be put on a shorter 14 day orbit around the planet. The plan was changed, however, due to the fact that two valves in Juno's engine were not working properly and so the programme was delayed. The onboard computer is now working properly and it volition hopefully make a total fledged recovery. It is very disappointing indeed that nosotros missed an opportunity to get more than information on Jupiter during this flyby. The first flyby on 27th August gave us heaps on fascinating data and provided researchers with a glimpse upwards to 400 km beneath the clouds that encompass the giant planet. According to Bolton, "With [the data], it is equally if we took an onion and began to peel the layers off to encounter the structure and processes going on beneath. Nosotros are seeing that those beautiful belts and bands of orange and white we see at Jupiter's deject tops extend in some version equally far down every bit our instruments can meet, but seem to change with each layer."
The next flyby will have place on the 11th of Dec and hopefully Juno will be fully functional then and all problems will be sorted out and no unexpected events spoil our plans.
