Science is all about genuine curiosity for what surrounds us. And I believe that if everyone on Earth embraced their true "scientific" nature many problems would be solved. To begin with all existing inequalities. Science tells us that that there is no difference between humans. It teaches us that, in the end, we don't live in the Universe because we ARE a...

Love it.

Davide Odorico replied to Trevor C
Great! Go for it.
-
Don't bother about the formula, all you need is the concept that lies behind it. ;)
-
I'm glad you're enjoying the course, Vicki.
-
That's what they did...with unmanned missions though. And the results were very interesting.

I think the history of this debate, about the existence of water on the Moon, is very intriguing. For any supporting proof, there was a proof against it. There seemed to be no peace.
-
Davide Odorico replied to bill hood
I couldn't agree more with the last sentence.
-
I think that no science debate is really finished. Science is all about progress, and as we progress we get enhanced technology which can lead us to new discoveries, and everything we believe is put at stake again. Take an example quantum physics.
-
That's exactly what the scientific method is all about! Great!
-
Water is present in all our Solar System. That's interesting, because life as we-know-it thrives in water. I myself was very surprised when I wen through week 6 the first time I took this course.

My favorite week :D

Davide Odorico replied to Davide Odorico
@AngelaL Great!!! :D
-
Seeing it really makes a difference.
-
Davide Odorico replied to David G
Thinking about costs, I think the latter would be a better option. Once it's in orbit it stays there. Besides I think it's easier to dock spacecrafts in orbit rather than land them on the Moon, only to launch them again into space.
-
Keep up with the course's steps and you will find out.

What always amaze me are the timespans involved! We're nothing compared to them - we live, on average, 75 years. That's why Geology is important, it makes us understand these huge changes and movements of Earth's (and other bodies') crust.

Hello to everybody and welcome to WEEK 5! This week is all about lunar geology! You might not like it as much as the other material in this course. There are a lot of notions to take in. However, bear in mind that geology is very important. Not only for a complete understanding of our Moon, but also to get a deep insight in the history of our every planet....
-
Davide Odorico replied to Anne-Marie C.
Don't worry too much about the result. As long as you're interested and you learn something new you're doing fine. :)
-
Davide Odorico replied to David G
That's why they were cautiously "packed" for re-entry :D
-
I'm glad you liked it!
-
Davide Odorico replied to Ellen Papenburg
That's an interesting observation. It must have something to do with the location of the heat shield of the spacecraft, however this is an artistic rendering.
Just have a look at this NASA video when you have some spare time. The whole re-entry science is explained and it's one of the most mind-boggling stuff I've ever seen. I love...
-
Davide Odorico replied to Ellen Papenburg
It does make you think a lot.
-
Davide Odorico replied to pamela roskilly
Great! Thanks @MarkGray :D
-
Davide Odorico replied to David G
Indeed. Tectonic activity recycles the Earth's crust and the oldest craters are gone after some million years.
-
Davide Odorico replied to James Stewart
We're so lucky to have our beloved atmosphere. Not only it permits life to exist but it also protects us from all of these little asteroids.
-
Davide Odorico replied to David G
Great recap of al the variables! Don't forget gravity is important as well to understand the scattering of the debris left by an impact.
-
Davide Odorico replied to pamela roskilly
Hold that thought, guys! You'll learn more about the lunar maria when we'll explore the geology of our moon during WEEK 5. Volcanic eruptions did play a role in shaping the moon's surface in the past.
-
Davide Odorico replied to pamela roskilly
More than the atmosphere is the planet's gravity that affects the most how the debris will scatter around the crater. Keep on going on and you'll know more in the next steps. :)
-
Davide Odorico made a comment
Crater-science, here we go!!
-
Davide Odorico replied to David G
Hold that thought till Week 8. We'll cover more in detail what is life-as-we-know-it. It's essential to know exactly what life is before looking for it elsewhere.
-
Davide Odorico replied to John Cope
It's great to hear that you like the material, guys!
-
Davide Odorico replied to Brian Chalmers
Fascinating, isn't it?
-
Davide Odorico replied to Gaëlle Giesen
I think it must do. Consider that Ganymede's magnetic field is embedded into the magnetosphere of Jupiter, which is 20,000 times stronger that Earth's. It begins to avert the Solar Wind 3 million kms before it reaches Jupiter.

The triangle of fire includes fuel, oxygen and heat. On Titan either heat and oxygen are not present. I think that's the reason why the atmospheric gases wouldn't ignite if electric storms were to exist.

Perfect!

I love that movie.

Welcome to week 2! This week you'll discover how craters have a science of their own. I hope you'll like it. Enjoy!

Davide Odorico replied to Ken Evans
Indeed.

Davide Odorico replied to pamela roskilly
Earth does wobble. It's a slow cycle called precession. Have a look:
-
Davide Odorico replied to Vicki Brown
There are indeed retrograde moons. Likely captured and not formed in situ. Triton is a good example.
-
Davide Odorico replied to David G
Good! I hope you'll learn more and more from us. :)
-
Davide Odorico replied to Anthony L
I like your comment. The fact is that, for example, the Moon and the Earth are considered like a binary system that, together, orbits the Sun. The are indeed bounded gravitationally one to another.
-
Davide Odorico replied to Geron Kees
@GeronKees Although without its regulatory influence on our axis, axial precession would make seasons way more extreme on our planet. :) I don't think it's necessary for life to exist, I just think the moon, in our case, helped a lot.
-
@RichardWright Thank you Richard! :)

Good luck with your first quiz! Don's stress, just have fun. :)

I don't know if anyone of has seen this BBC documentary, but it's mind-opening.
https://www.youtube.com/watch?v=I1_TZqAO76A
It's about the moon and its influence on life on Earth.
I personally think life wouldn't have evolved the way it has without the stabilizing effect of our satellite. However, life is like a spreading and highly adaptable virus...

Apparently, it's not only about companionship, but it's also about the very development of life and how our satellite influenced it. :)
-
Davide Odorico replied to Geron Kees
Considering the whole Solar System is 5 bln years old, it would be interesting to know how this hypothetical life would have evolved until now. Look at how life has evolved on Earth. Great comment Geron, thanks! Keep it up!

When I first took this course I was very impressed that ice could behave like rock. Science is mind-boggling.

Davide Odorico replied to Sylvia Vickery
Geology is tricky sometimes. But don't worry, you're not alone. Many people, including me, struggle with recognizing samples and fully understanding the chemistry behind geological processes. However, as long as you keep your interest for our Universe alive, you are in the right place. Keep it up!!

Davide Odorico replied to Ian Kershaw
Thanks, Ian. I hope you enjoyed using it.

Thanks for sharing, Lorna.

Davide Odorico replied to K T
The radiometric dating gives you the "age" of the sample you are analyzing. Usually the samples we're able to analyze on Earth all come from the Solar System, which is approximately 5 bln years old, so they can't be older than that. If you found a sample, say, 10 bln years old, well, that surely wouldn't have been born in our Solar System.
Besides, the Big... -

Science is indeed impressive. I'm glad there are so many people out there (like all the participants in this course) who marvel at what we humans discover through science. Not everybody does.

The best video of the whole course!!
-
Davide Odorico made a comment
I love the course supplements. I usually go through the course with my laptop and I use the supplementary pdfs on my tablet. It reduces a great deal the amount of notes I have to take down. Excellent idea!
-
Imagine the "D" shaped crescent Moon in London transitioning to a crescent "C" in Rio de Janeiro. Clearly you pass through a crescent "smile". :)

Don't worry Annette. You are all here to learn and we will always support you!! :)

Now you know why. :)

Not many people know this.

So had I.

Davide Odorico replied to Peter Burns
What a great idea!!!

Davide Odorico replied to Joan Laing
Anything orbiting something else is called a "satellite". I think we could use this word.
-
Davide Odorico replied to Peter Burns
I like your point.

Definitely not easy to name them all.

Here explained the "dark" (we'd rather say "far") side of the Moon.

Davide Odorico replied to Joan Laing
It's got to do with eclipses. Good comment, Joan.

You'll see they can be spongy too. Keep on going on with the course.
