I'm easy to please, I see an Eager Space video, I click.

[king_brk]

The old intro works great as an outro, and definitely keeps the unique charm of this channel
You are one of my favorite space educators, with a unique analytics based approach
Keep up the amazing work

[mrrolandlawrence]

what a lovely surprise! watching eagerly.

1:25 Paused the video right there and joined the new subreddit. Yay!
Sometimes my answers in r/spacexlounge consist of a link to an Eager Space video, especially "Commercial Moon - Starship, Dragon, and Starliner". Those will give a more through answer than I can - and one that's backed up magnitudes better than I could do.

I'd recommend "Ignition! An Informal History of Liquid Rocket Propellants" by John Drury Clark, it's a fun read.

[Samonie]

these video's are great, please keep uploading. i can't think of any other youtube channel that explains the niche space flight industry as a whole better than you

[rohanbaty]

I love this channel! It s nerdy space stuff that is well explained for other lower level budding polymaths. When I try to talk about some of this stuff to anyone else their eyes quickly glaze over. Keep up the videos, much appreciated.

Pride and Prejudice was not in today's Bingo card, but I agree the 1995 version with Colin Firth & Jennifer Ehle is by far the best screen version - leagues better than the Keira Knightley one.

Strange to come across 3 scifi books I've never read. I love all kinds of scifi especially the ones that are more toward actual science. Love all of Alistair Reynolds, Project Hail Mary, Children of Time, The Three Body Problem, The Saga of the Seven Suns, The Expanse and The Foundation series to name a few

[PetesGuide]

Tachyon tablets, etc. as the outro is perfect!

[MarcAus]

Wow ive read one of those recommendations.
Totally didnt expect to see Tanya Huff show up in that list.

[Bigbruce]

Thanks for answering! I didn't expect such an interesting reason.

A video on electric propulsion for larger spacecraft (perhaps crewed) would be cool. Personally I'm doubtful about them, but it wouldn't be the first time you've changed my mind.

[asper]

Bro started pumping videos like these are easy😭 Keep up the work!!

HEY, I have watched the Sabor program for at least 10 years. They did go out of business once years ago, probable 230 years ago. They had a Brake through with the incredible cooling system they developt to cool there fuel to a ignision point they needed. I do know the Secret Air Force project gave yjem 90 milliom back then and the ESA gave them 60 or so million. But I have not heard anything lately.

[SKYWURX]

A few years ago I was really interested in Reaction Engines Inc. and the SABRE concept.
I even spoke to them when they were exhibiting at Farnborough International Airshow.
One of the (many) difficulties of the SABRE engine was the precooler, which used novel methods and technology that they have patented to use the cryogenic fuels to pre-cool and therefore compress, atmospheric air.
It doesn't take much thought to realise the biggest problem with that is the instant icing that would traditionally occur when moisture laden air travels though this cryogenic heat exchanger.
However, they built a full scale prototype of the precooler which worked successfully.

I imagine the company has pivoted from the grand ideas of impractical SSTO's to heat management solutions since its the best way to make ROI on their IP.

Still love the idea of the SABRE engine though 😅

[bwjclego]

Heh, I forgot about the Tachyon tablets.

[ilkoderez]

James Burke, I have all of his series downloaded.

[SirDeadPuppy]

i want to see a bunch of end credits skits tablets! exlers! and calming transwarp balms!

[Izayuukan]

I think the old intro makes a decent outro.
