Imagine standing on the shore of Lake Michigan. You see nothing but a vast expanse of water, deep and alive with currents. Now imagine that isn’t Lake Michigan, but the shore of the Gale Crater on Mars.
New pictures, taken by NASA's Curiosity Rover show thick slabs of dried sediment that look familiar to anyone who has seen a long dried up patch of water like a creek bed or a lake. Only this patch is on a massive scale. This is exciting to scientists who are looking forward to studying the sediment to find out just what happened to the water.
“You don’t need magic new science to understand the geology of Mars,” notes Janok Bhattacharya, a sedimentary geologist at McMaster University in Hamilton, Canada, as quoted in Science Magazine. Basically, geologists here on Earth can study the pictures and sample analysis sent back and make strong assumptions about the Martian climate based on how it matches up with what they’ve modeled here on Earth.
So far they do believe the water was in large bodies, with currents powerful enough to move the larger, more rounded rock sediment they've seen. They can also see how the sediment piled up over what could be millions of years, and possibly decipher what the layers meant about the changing climate on Mars’ surface and if there were different climates like here on Earth.
It goes without saying that scientists, geologists, and astronomy buffs are beyond excited about what the Curiosity Rover has been able to show us. This is big news and a big step in understanding other worlds. The geology discovery that lies ahead is going to be rich in data thanks to the Rover, and we can't wait to see what comes next!
As we ponder a now mostly dry planet and what it will tell us about life on Mars, or perhaps if we are seeing the future of our own planet, we should also stop and appreciate the tremendous feat of technology and engineering the is the Curiosity Mars Rover.
If you want to understand what an achievement it is to have these pictures and data coming back from Mars you won’t want to miss Red Planet Rover Tuesday night at 9P on Science Channel. You’ll get to follow the build and the journey to Mars from the eyes of the mission control team. This is their baby and they’ve invested their time, theories, and hope in this amazing spacecraft.
It’s all part of a night of intense space exploration. There is truly something for everyone who is wondering about the universe.
What’s On Tuesday:
8P - How the Universe Works: Forces of Mass Construction
9P – Red Planet Rover: See the Mars Curiosity Rover as You Never Have Before
10P – Space’s Darkest Secret: Can Scientists Crack the Mystery of Dark Matter?
