[An unmanned visit to Challenger Deep this week.](http://en.wikipedia.org/wiki/Challenger_Deep#Nereus) Don’t have much to say about it except that the only reason I even know what Challenger Deep is is because it used to be a favorite reference here on the SDMB. ---

I had searched “Challenger Deep” - no results - rather than “Mariana Trench”. ---

But you have to stuff up the original post. Otherwise it doesn’t make sense. ---

I was watching a show about the previous expedition just a day or so ago. One of the explorers spoke of reaching the bottom but then hearing a loud “pop”, thus necessitating their departure. When he said “but we only got to stay for 20 minutes” I had to laugh thanks to, of course, the sdmb. ---

I’ve often wondered about the water pressure at that depth. According to Wikipedia it is about 109 Megapascals or about 1,075 times greater than atmospheric pressure. :eek: That could explain the crack in the window.
