At 1754GMT on 4 July 2015, NASA’s New Horizons mission fell into a safe mode after its primary computer crashed after an overload condition cutting communications with Earth. The overload was caused when a commands upload ahead of a Pluto flyby happened at the same time as a data file compression activity was taking place. The spacecraft managed to switch to a back up computer and communications with Earth were re-established at 1915 GMT the same day. While some data observations were lost during the approach to the dwarf planet Pluto the spacecraft was fully recovered by 7 July redly for its closes approach on 14 July 2015.
