- Many robotic spacecraft have been sent to explore the cold, dry and dusty surface of Mars. They reveal a world not so dissimilar to Earth, shaped by meteor impacts, volcanic activity, weather and flash flooding. In addition, recent discoveries inform us about the possibilities for life on Mars -- both in the past and the present.
The transcript and downloadable versions of the lecture are available from the Gresham College website:

I am finding myself addicted to Professor Carolin. These lectures ROCK!
This Prof is a fabulous communicator of quite complicated science for the layman,
She is now a TH-cam fave of mine
Thanks for the upload as always.
Me too!
Awsome lecturer. Can’t have enough of her presentations.
Expressive and detailed descriptions without pomposity or artifice!
Always a pleasure to watch Prof. Crawford's lectures. Thank you.
Great to listen to. Awesome teacher.
She's a great lecturer!!!
Carolin Crawford is awesome. What I wouldn't give to have dinner with her!
She's my new lullaby lecturer. used to be dan barker
I fell asleep to this last night... not that she's a bad speaker, she's an awesome speaker. I even caught my self saying "Oh, wow, that's interesting..." in my sleep. Yeah, I'm totally watching this again.
Excellent lecture.
No doubt a higher achievement than putting a robot on a distant planet. I applaud you!
Carolin, magic as always, and very much in focus as of today, you sound very like my lead tutor at Liverpool Uni Msc., but better.
Another great lecture from the prof and I look forward to the Quazars lecture at the end of the month.
Can we submit other people for the trips to Mars? If so, there is a large group of politicians I'd like to see doing some scientific exploration. 🤓
At 33:56 she suggests erosion from melting CO2. That would require very high air pressure to get a liquid. It is only possible at above 5 earth atmospheric pressures, and even then not likely.
Good job!
Kuato Lives!
One question that occurs to me is where did all that perchlorate come from? Perchlorate is one of the strongest oxydizing agents there is, so it's surprising to me that large amounts were found in the Martian soil. Can't imagine that it's good for the wheels of our rovers.
Good lecture, but about actually travelling to Mars? I like it here too much.
Is there anything this lady doesn't know about current scientific understand in astronomy?
Okay everybody lets go.
Please watch The Lightning Scared Planet. Thunder Bolts Of The Gods . A very interesting video.
the effect that is show in the crater photo at 23:19 which she mentions as a 'crater within a crater' has been studied on earth at the Chicxulub Crater location, and believed to be the effect of one large impact onto rock rather than two separate impacts (that was at least my understanding) I watched the theory explained here: www.bbc.com/news/science-environment-38019604
Wow, could that Italian Dude, have seen the dust devils, and mistaken they were canals? because no other feature on Mars resembles any Canals but those "Dust Devil's" Because that must have been a powerful telescope for that time. or unless he saw the scar on Mars and mistook that for the canal?
great lectures, simple enough so the Americans can understand, but still enough information to keep it interesting, great job!
lol wtf is it with u euros, there is nothing u do that we don't do better. been to europe, met lots of stupid people.
A European has a basic understanding of the world, an American does not. Just ask an American to show you Afghanistan on a globe and youll get my drift.

You're welcome for all the NASA photos in this lecture. Sincerely, the USA.
I was born and have lived in the UK for 78 years and have known masses of smart people. Well, at least six anyways.
i thought it was widely accepted that the moons of mars were actually from mars itself
She didn't mention that because Phobos orbits Mars so quickly, it rises in the west and sets in the east.
Seriously, why do they not ring out these PA systems so you don't get shitty frequencies feeding back. Cut 2K!
Three words : FIX THE AUDIO !
forever a long way off research $$$$$$$$$$$$$$$$$$$$$$$
What a wonderful white lady..you are full of knowledge..please can you in style reveal to us in future if ufo are real.
How much does all the shit she is talking about COST? It is a big waste because you cannot use it for anything real. And how much more expensive is astronomy now than 50 years ago? The life on Mars they are talking about would be like bacteria. It took bacteria 3 billion years to be something more, and then it was slimy worms and crawlers. The cute annimals did not appear until 70 million years ago. It is all just´´an old womans story´´.
In a different lecture a questioner at the end asked her, "But what's it all good for?" She looked at him a moment and asked quietly, "Sir, have you no soul?"
If NASA had been given the money wasted in the Joint Strike Fighter we'd have permanent colonies on the Moon now. It's sickening the priorities our culture has, where we can spend over a trillion dollars to brutalize a 3rd world country for no discernible reason at all but NASA has to grovel every year just for the pittance to continue monitoring the Voyager spacecraft as it exits our solar system.
British accent is so annoying.
I did not notice any accent (Tony, London)
More seriously, you probably find her voice annoying because it sounds very much like a working class London accent (like mine) which we are not accustomed to hearing from educated academics. I too find it annoying coming from a lecturer, even if I sound the same (or because I sound the same?). My preferred speaking voice for lectures is Sean Carroll.
