#2As someone who loses sleep whenever he submits an app update to the App Store, I can't even imagine... Good luck to everyone working on this mission -- it's an awesome one.

#3Thank goodness! Looking forward to the Pluto close-ups, which will hopefully include the dark spots.

#5Ever since I was a wee kid I wondered what Pluto looked like. When the news came that there were issues with New Horizons just DAYS away from finally coming close to Pluto my heart sank.
It's very good news to hear it's back and will be good for the fly-by. I'm so excited to finally see pictures up close to this planet / dwarf planet!

#7I'm getting a plain black page from this link in both Firefox and Chromium. For the people that the link works for -- is there anything else of interest in the post beyond what's in the title and the previous story posted earlier today?

The key paragraph is as follows:
"The investigation into the anomaly that caused New Horizons to enter “safe mode” on July 4 has concluded that no hardware or software fault occurred on the spacecraft. The underlying cause of the incident was a hard-to-detect timing flaw in the spacecraft command sequence that occurred during an operation to prepare for the close flyby. No similar operations are planned for the remainder of the Pluto encounter."

#10Holy hell, talk about a high-stress debugging situation. And then you have to wait 9 hours to see if your fix actually worked...
