Thank you Fraser, again, for another great video - as always! Also thank you for taking the time to talk to me when I became a Patreon. The discussion we had was interesting and it was nice talking to you. I am impressed with the work you and the other staff are doing. I am really impressed actually. And it´s very interesting content. Thanks again! Take care. BR //M

'Eager Space' is my favourite underrated channel, it combines science, rocket engineering and related subjects in a way that is easily understood, but only has about 4.3k subscribers. The basic graphics may not be to everyone's liking, but the content is gold.

Cait had the best question and answer. It was also great to hear about possibilities with larger rocket payloads

I've always wondered why they weren't using lasers for high bandwidth comms. it was possible even at least ten years ago, now, it's ridiculously cheap because of the low cost of high power solid state lasers. Radio waves are not very directional, and thus heaps of energy is lost, but lasers ARE very directional and you can really crank up the bit rate and do it over multiple frequencies as well, it's a no brainer really, plus, because they are so directional, they are also much harder to intercept !. In fact, with time based crpto , they are probably 100 percent secure.

My question: how cold does it get in the shadows on the Moon on the sunlit side? Does it get as cold as the night side of the moon? Also, love this channel! I've watched dozens of videos multiple times, especially if I listen to it to help me fall asleep (not out of boredom!). You just seem incredibly chill, passionate and knowledgeable, Fraser!

So prolific, thx Mr Cain, we enjoy it (I joined lately last night, these summaries are convenient)

Re small channels, Parallax Nick is criminally under-subbed. His content is so unique, so well researched, and so well written. For the life of me I can't understand how his channel isn't bigger.

Escape velocity is always the orbital velocity times the square root of two. So of you can get the nuclear waste out to the Oort cloud, it's still cheaper to eject it out of the solar system than to have it fall back into the sun. Nuclear waste still has a lot of energy left in it so it's probably better to put it somewhere you can reach when it becomes economically viable to recycle it.

Let's go with Vulcan ... the answer to that question has a very high yield '''

Hey Fraser, if the NASA budget was doubled, what kinds of missions do you think we'd be seeing?

By far the simplest way to get the water from the regolith, is simply to heat it using the sun, it gets well over 100 degrees Celsius on the sunlight up there, so it's just a matter of using solar charged vehicles to transport crushed regolith to a solar furnace and then take the steam and run that into a turbine to produce even more energy, the cooled steam then has lost enough energy to condense out, and there you have water, power all in one.

Fraser, I think a very useful comparison is to show the area of the sky containing the Andromeda galaxy with the moon for scale at natural eye levels then turn up the gain until you can see Andromeda.. it's a bit of an eye opener so to speak.

Vulcan and Remus. The entire video is fascinating,( pun intended ) but these two really taught me alot. Thank you.

Hey Frasier, one of my favorite science communicators with under 10K subscribers is spacemog. Pretty sure I found her through one of your past videos. Thank you for all of your content!

Interesting. I never knew that there was such a thing as a "Hubble Palette". Makes sense. You learn something new every day!
