Tbh descending to the bottom of the Marianas Trench and returning back safely is just as impressive of a technological feat as landing a man on the moon.
Middle of the night tv
Notice how they didn't make a submersible made of carbon fiber
I miss when the history Channel use to be like this
If I heard the outer glass crack I'd have headed back up. Insane they kept going.
I show this in my earth science class every single year. One of my favorites
I find it fascinating that 1 - Sonar was created to find enemy subs, now used to map ocean floors, 2 - Radar was created to spot enemy planes, now used to monitor weather and 3 seismometers were created to pick up atomic bomb testing, now used to monitor earthquakes
Watching this at 2:57 AM bc I started thinking about the ocean floor and had to know 🤦♂️
the glass cracked and they decided to continue... they must have had a 2nd sub just to carry their huge balls!
“The seafloor at the Marianas Trench is so old because it’s been so long since it was born”, a truly profound quote! 35:45
Man, remember when the history channel was... good?
The real truth is the only thing that's consistent is change. Everything in nature is always changing.
Can you imagine paying out 5 miles of line by hand, and then hauling it back in? Just the thought exhausts me, and i was a line-handler on a carrier.
He said people ask all the time why can’t u just send a robot and he said we gotta be there cuz that is what we do 💪🏻💪🏻
"Self portrait" = selfie lol And spoiler alert, James Cameron went to the trench in 2015
Mind boggling knowing that the Mariana trench is more than 1500 miles long and about 45 miles wide!! It's not just a deep hole
By far the boldest terrestrial exploration so far. Imagine what’s next.
I’m so baked I thought the title meant the trench made the earth
I’m glad we know FOR SURE that Earth is a planet. The intro was hinting at that.
I moved to Guam in Jan 1961, my dad work for the US Navy, I was 14 yrs old. The thing that actually scared me was knowing how close I was to the Trench. My dad told me about it on flight over, I thought Gee thanks dad!! I left at 22yrs old and dad left about 3yrs later. Oh yeah, we sailed over the trench on vacation to the Philippines in a troop transport ship in 1963.
