Dr. Penelope Boston, NASA Ames Research Center
New exploration indicates that caves may be more common on rocky and icy worlds in our Solar System than we have thought in the past. Caves below the Earth show us a very different planet than the familiar one we experience on the surface. Each dark cave system has its own micro-organisms and distinctive mineral and chemical properties. Dr. Boston takes us on a tour of the some of the most spectacular caves under the Earth and the unusual life-forms they harbor, and considers how the lessons they teach us can be applied to the exploration of the Solar System, especially the icy moons of the giant planets.

Andrew Fraknoi is my favourite Professor of Astronomy, Emeritus and yet I have never seen a lecture by him. He just seems like a really nice bloke.

My neighbor is only 70000 years travel away and 70000 to get back. That takes us back to the origin of Homo sapiens.

Back to the moon, you say, must have found the lost data.

Art deserves more than a mention.

I turned it off after 20:10 comment. If we can find dinosaur bones, then people 200 million years from now will find glass bottles, ceramics, and tons of other man made stuff.

@maan7715 5 лет назад

Well we don't find actual bones, but the cavities filled with minerals- fossilised bones, and glass breaks down after one million years. And if our civilisation disappeared in a few thousand years, this really short period of time when we made these materials would be a really tiny geological layer.

Cities. We’ve covered with extremely thick layers of cement thousands of square miles of the earth surface. If in our dynamic planet we can still find stromatolites a billion years old I bet skyscrapers will leave their mark as well.

@@pansepot1490 Exposed steel will be rust in a short time. Buried steel in 2000 years. Plastics will turn to oil under the pressure from millions of years of sediments and rock. Our mines will leave some imprint in the geological layers. Jewelry will last the longest on earth. The landers and rovers on the moon and Mars will last the longest.
