Best images of Mars I've ever seen. And I've been looking at Mars for a couple of years now. I'll be thrilled to see you cover Perseverance images & discoveries.

[davidarbuckle]

Great historical perspective of the successes and failures. Thank you for this.

[cheecharron]

Very interesting. I learned a lot thanks!

I never understand when it's said that certain things are essential for life and that without them, life couldn't exist. I presume the caveat of "as we know it" is implied, but it just seems like that could very well be an important distinction.

I lost the count of how many times I watched this wonderful video 😍 Wow ! It just blows my mind !

[SA]

Got the good knowledge, thanks a lot!

Clickbait, this is a history of Mars probes and landings, it says essentially nothing about what we know about life on Mars.

8:55 Mars Odyssey was not the first artificial satellite to Mars to have used aerobraking. Mars Global Surveyor already did the same thing years before.

Im so lucky to be alive and be able to watch these humans amazing achievement its amazingly rewarding experience...

[solarisnova]

Great video. Soothing narrator’s voice and calm background music makes an enjoyable experience for this type of content. I am a now a subscriber. Thank you!

[StarlitJourneys]

True exploration is not the land it covers but the journey it inspires!

I suppose if our telescopes had detected Martian people walking about on the surface, we would only have started a war with them.

[victoriagonzalez]

Such an inhospitable place, it would be a hellish existence.

How deep did the thermal sensor go. Did it detect any heat coming from inside Mars, like from a molten iron or at least a hot iron ore?

[lumbiniashutoshtambat]

Wonderful video, appreciate your efforts!

[mutaistudios]

Thanks for this! Im going to do my 6th yr architectural project discussing a small population sustaining itself on mars.Super excited!!!

Best channel. Best voiceover. Best graphics.

They call it the red planet but it's actually a tan brown planet similar in color to the Sahara desert with a Crimson blue sky like what we see on earth during the winter season's.

[richardanderson]

A slick production piece . Doubtful that it tells all that is truly known about Mars !

[ProlificInvention]

Nothing because we've never searched below the surface, there is a temperate zone under the entire surface of earth that stays at an optimal temperature... I hypothesize there is also a similar effect under mars, best part is no one knows and I may be right.
