content: 4.5 hours is correct! New Horizonts switched into safe mode few days ago, but they thankfully managed to fix it. Can you imagine operating something where you have to wait 9 hours for response? Absolutely incredible job. I can't wait for more pictures, I have always been fascinated by other planets, but was kinda sad we didn't have any high resolution pictures of Pluto, so last few days were fascinating for me!
