@pechelman cool threat! was always into space stuff
-
Thanks @endo ! It's really an exciting time, been working in space launch for 20 years and there's never been this much public excitement, engagement, and interest in it which is great to see.
Hopefully the few people I noticed talking about space stuff contribute and encourage other closet space nerds to come out.

@pechelman great thread! Love everything about space. I read the Trisolaris trilogy if that's familar for anyone, it's scifi but with a lot of cool ideas of how technology could change. Too bad that a lot of budget cuts in the space sector are happening.

I love space stuff too though don’t know much about exploration and associated tech. I do think it’s one of the most important endeavors our civilization can undertake.
I’m fascinated by cosmology, astronomy, and physics. Anything underpinning and explaining existence and how things came to be is of interest to me.
@FlavourFade thats a great series. So great I’m now hesitant to watch the adaptation on Netflix. It definitely is more “Fi” than “Sci.” I’m a bit puzzled as to how it achieved a reputation for being “hard” Sci Fi. Other than the character Luo Ji, my favorite achievement of the series is the Dark Forest hypothesis. I think it’s an unlikely solution to the Fermi (non-)Paradox, but as a literary device it is genius in that in brings a pragmatic form of cosmic horror into a work of sci-fi that is credible within the world of the series.
Think it, be it.

Very cool black hole simulation from NASA
Some other good ones here:

added these all to watch later @mclaincausey
thanks! -
Are you professionally involved in rocket launches @pechelman and if so, what are you doing (if you may speak about it)?
-
I can generally talk about it @endo, been working on rockets since 2004. The Starliner launch is personally significant because I did the mechanical design from the very beginning (along with a small team of ~4 others) for the structure that supports it on top of the rocket for nearly 7 years. It's mostly visible in that picture above with the large ring and white looking struts (which are remove before flight protective covers). I since left that position ~7 years ago and have been working on another large rocket, but I'd rather leave any names and specifics out of it for now to ensure I don't overstep terms of employment.
-
fascinating @pechelman what can you say about the postponing of the Starliner launch?
-
This is a pretty good summary of the situation. There's a valve on the launch vehicle causing some concern.

@mclaincausey i think hard sci fi is defined by a lot of explanation and not by how realistic it is but you are right, there's a lot of stuff going on that's a bit Fantasy like. But I loved all the political stuff and what he thought could happen to humanity in case of contact with aliens.
The Netflix show is okay but I think they rushed a bit and it's a lot different from the book which I don't mind but when you watch it I would try to see it as a separated thing

next to impossible without a system of harnesses, grips, and pullies that would make the most extreme domiatrix blush. -
@Matt I like the way you think
-
I want to watch that one too.
How about a debate: what should be the stacked ranking of space exploration objectives? Here’s a try that isn’t super well thought out:
-
survival: I think we need to eventually be able to live off world and colonize the solar system to de-risk a number of threats to our civilization
-
scientific discovery: I think that a lot of answers that could help with technological advancements will come from understanding our universe. So this includes experiments and instruments in space, and then the ancillary tech advancements that enable and accompany space exploration. This includes things like manufacturing in space free of the constraints of gravity, which overlaps with:
-
commercial concerns: there is money to be made and each nation and alliance will benefit from being ahead of the game; in this sense this is also a national security concern
-
-
My take is that it's not clearly any one of those 3 as listed @mclaincausey, but a mix of them.
Space is key to our survival, but in the sense we have to move hazardous and polluting industry off the Earth's surface and use the abundant natural resources available from space to help preserve this planet and its population. There is no better place we know of yet than Earth. From this effort of moving people to work and live in space to benefit Earth, huge advancements will come relating to scientific discovery and also commercial opportunity.
