What the hell have I been watching on TV all these years?
Where were serious informative subjects when I was growing up?
Your channel makes it hard to go back to watching regular "reality" TV !
It doesn't get more "real" than this!
Bravo!

I'm always in awe at the patience of people who run deep space missions. The thing blasts off and then you have to wait ten years to see if it actually works the way it's supposed to.

I love that all your videos includes actual images. This was absolutely breathtaking!

9:37 One correction: The experiment carried out after reestablishing contact was CONSORT, which is a radar instrument. It was not the drilling experiment as claimed in the video. The drilling experiment could not be performed because the lander was not in an up-right orientation.

This is one my favorite YouTube channels to watch in all categories. Great video as usual and the cliffhanger adds more spice to it. Thank you.

Impressive how close it went on its several flybies. With all the millions of kilometers between the objects in space, 250 km sounds like touching distance. I wonder how difficult it is to maneuvre it so precisely.

Press F to pay respects to brave little Philae :'(

[PurpleHeart]

Dammit harpoon! You only had one job! Just one!🙃

[xyzct]

Could you imagine how exciting it would have been had the lander anchored and gathered data for months!

[JackieWelles]

10:28 only one leg sticking out like shouting " Hey i am here guys !" is kind of cute i think :D

[John-hdux]

Been waiting for someone to dedicate a video to this landing. Great video thanks

Only a month ago I invited taff Morgan to my offices presenting about Ptolemy And Philae. He was engaging and his talk was informative. A unique view with insight into Cassini, beagle2 and Philae and new horizons. You should try to interview him. He’s brilliant. Based at Leicester open uni.
Guy is legend.

Did anyone else have a feeling of sadness? When Philae went silent for good...

Your channel is most certainly the best Space related YouTube Channel on the platform. Thank you Astrum for bringing us the strongest of Space knowledge! <3

[pranayagrawal]

Yet another one of those great astrum stuff.
You are doing your job really well by making humanity aware of such amazing things.
Good job. Keep it up ALEX.

[PrimeG]

Very well done once again! It is so satisfying to watch such good visuals and listen to your voice full of excitement about these topics.

[DanielZajic]

Wow wow wow, what a video!! Absolutely amazing stuff, mind blowing. You are doing such a huge service to humanity by presenting this content the way you are doing. Thank you so much.

[TheJohnblyth]

I always get excited when I see there’s another Astrum video. Thanks!

[mechanicjobs]

This exploration of space fulfills the deepest ambitions of humanity.
