[Q&A+] Understanding Universe's Scale, Mars Missions, Colonizing Gas Giant Moons

I think the interviews are great as they are. Your questions show your great knowledge and enthusiasm for learning something new. The answers are very interesting and your choice of person to interview suits me very well.

Moon outpost question: Do we know if there is an effort to standardize units of measurement on the moon? Will it be metric or both metric and imperial?

Missions to Mars. Yep. We've all see the confident posts on "in situ resource utilization". As someone familiar with that process right here on Earth I was usually left shaking my head. Countless other details about hypothetical Mars missions just didn't add up. From the early days of Mars mission discussion in the private sector it seemed more of a fundraising pitch than an actual plan.

Isn't it a shame that the US made no mention that the ESA designed,constructed and delivered the service module for Artemis,yay America!

PS I'm in favor of as much content as you can produce, not less

The interviews are excellent as are and don't need summaries. However I would find it very helpful in understanding the concepts the scientist is conveying to have a 15 second rewind and fast forward in all content you produce - including your own Q and A's. Right now some do have it and some don't. Many times I find I need to hear something more than once, and without the rewind it can be difficult.

Regarding Interviews (and sorry if I’ve missed the gist of their question/comment)… If/when an interview segment leaves something unclear to me, I follow up by looking for relevant content by other science communicators. Like: Dr Becky, DeepSkyVideos (and other Brady Haron channels), Sean Carol (on Patreon), even Answers with Joe to help me fill in voids in my knowledge/understanding and sometimes go back to that part of Fraser’s interview. I know. I’ve turned this into a study regiment but it’s what I do with my time. I don’t watch movies. Can’t stand TV. Read too much already to keep up with my profession. Fraser’s interviews feel like where I go from SubjectMatter 101 to the next level some times.

Hey Fraser, If we do make it to Mars and people are living their lives, because the 1/3 gravity would humans grow taller? Thanks for everything. JD

I love the interviews you do. I am often amazed at questions being answered about issues I had never considered. Please keep on inviting guests and blowing my mind. Thank you

Thinking about going to mars, taking everything that's needed to survive and spending all that time in space, a question has popped into my head. How much toilet paper would a crew of astronauts need?

To the interview question: great as they are. The feature is not available on Patreon, but on youtube its possible to add “segments” or “ chapters” to the time-bar and on the side for each question. That could be a plus for people who want to scroll through certain parts or get an overview. I always listen to the whole interviews on Patreon but some people on youtube might find it a good add-on.

My favourite science fiction series, The Expanse, attempted to show space as it is. Vast, empty and completely implacable. Yet, when I look up at the night sky, all I feel is wonder and amazement. Until we look up and see the Universe as it is, I don't believe we will be able to attempt to move away from our planetary cradle. Space can't be made safe, or comfortable, or mundane. We will always have to be operating at 100% efficiency to stand a chance of survival. That's a tough ask.

The interviews are excellent as they are. I love when you try clarifying a point for yourself, 'cos it clears things up for us too. My only suggestion would be perhaps, interpretive dance.

Fraser. (This from a Frazer)... I can't help but think we need to look at the universe differently. (Not just our galaxy --- the universe.) Sure, throw in dark matter -- red shift and all else. When I look at it; in big scope I see dendrites, neurons and something much bigger. I sometimes believe we think too small. Secondarily. Integrity and the kids were terrific. What a fine crew. Jeremy is from my city. A good re-step. I did watch the boys land on the moon and all missions from Ranger. Always felt a bit bad for Mike Collins. Tertiary. There was never a better Sci-Fi program than 'The Expanse'. We can do nothing until we create a better faster drive.

Here's an interesting thought to place ourselves in the context of the universe. If the Milky Way were the size of the continental United States, Earth would be roughly the size of a microscopic virus (about 60 nanometers).
