Cleo, end of this year please do a 2026 recap on optimistic science and tech. You can even include tech that you didn’t have time to include in a video. So far, no big YouTuber has done that and I think you’re the best person to be doing this. Thanks!

The one best optimistic astronaut

my favorite channel! everything you do is so cool!
@
How cool... How awesome... How wonderful... AMAZING!
Such a wonderful presenter, reaction, and human breakdown of the story. Totally wicked, thoroughly enjoyed this video, many many thanks to all involved.

I realized how big this entire thing is space exploration, so much work research testing is required. I realized how much patience these scientist need :)
Thanks for this video.

I've been following you for a while now.

All your videos are awesome
@
great vod but i love the built in ad timer. amazing little idea
@
10:21 The only problem is that it's a one-way solution. If you want to go back, you're screwed 😅.

10:33 “results from the ground” goes hard asf in this context
@
Love these bonus episodes! Cant get enough

That is the coolest plane ride ever. The Gold Ticket of aviation. I had to test fly 787s when they came off the line at Boeing, and tried to get them to put this on our test card. They asked why… I had no response except “because I really, really want to.” Boeing, it turns out, is no fun at all.

You just lived my dream. Not only is that huge, but it’s true.

0:35 I mistakenly heard "falling lavatory" which, is probably also true

Not sure if this was on purpose, but I appreciate that your mug is turned so the “G” faces the camera, haha

Using the sun instead of carrying fuel is indeed a LIGHTER way of traveling

This is proof that science and engineering are forms of art. The slow-motion shot of the experiment in freefall was mesmerizing. It would make a stunning abstract wallpaper. The beauty of physics! ✨

I grew up in the 60s with the first moon landing - and Star Trek. The future seemed exciting and bright. I've lost that feeling over the years, but your channel brings it back to me. Thank you so much! Of course, I also appreciate you wearing the Star Trek UFP and Starfleet Command patches.

Of course someone named John McFall would be in a video about gravity
@
bro, how do you get to be a trauma surgeon and a paralympic sprinter in the same lifetime, that's so cool
@
I love how often "Huge if true!" actually is the most fitting way to describe these experiments! 👍
@
So many cool science, right? 😎🛫
