Logged on to G+ today and had a super interesting conversation with someone from NASA. Really cool. What do you think the future of space travel looks like?

Also, sorry for the formatting, it's hard to bring G+ stuff on OT. (My profile https://plus.google.com/106702324621449002266/posts you won't be able to see the thread, since she posted it first )

Topic: And, honestly, this is what happens when Congress tries to pretend they're engineers.


Preliminary NASA plan shows Evolved SLS vehicle is 21 years away | NASASpaceFlight.com


A new schedule, created by NASA, has provided a preliminary, budget restricted manifest which places the first flight of the fully evolved Space Launch System


Me+ - This is what happens when society has no shared dream or hope. The spirit of discovery, innovation, education and pioneering has died off, and now the only thing left is the public's addiction to reality TV and celebrity drama instead of the advancement of mankind.

Other dude+ - I expect in 21 years we'll have more advanced technology.

9:26 AM


Her+ - Oh, I agree with you, and it pisses me off. The reality TV crowd keeps bellowing to cut our funding without realising how much came from/comes from NASA (and how little funding we actually get-- ferchrissake, we get half a percent of the federal budget, and it's not like we ONLY do manned spaceflight). There's also a very disturbing trend of "edukashun is fer eleetists" in this country.

However... Congress IS trying to dictate how to design our next vehicle, and it's based on wanting products from their districts, at the lowest possible cost, as soon as they want something. I think we'd be much better off if they'd back off, fund us, and stop insisting on Shuttle-derived tech.



Her+ - Whoops, didn't see the intervening comment while I was typing-- I hope in 21 years we have more advanced tech, but that requires drive, funding, education, and research. ...Goddamnit, I want to be walking on the moon before then. :P

9:28 AM

Me+ - Totally agreed. NASA should be an organizing that's there to do science for science's sake, and promote our quest to discover our own universe. Congress deciding what it should be doing is terrible. Fund NASA, promote certain goals, but don't dictate what the brightest minRAB in the world should be doing. That's not how you get the most out of R&D.

Imagine having a colony on the moon, with a telescope on the dark side. An opportunity to find out so much more about our universe, while advancing science way beyond our current capabilities. Totally recyclable living, low gravity life, space transport, etc. Or imagine a colony ship to join in your old age, frozen for a set amount of time so that when you wake up in a thousand years, you live your last few years beside another star.

Oh well, the pioneer spirit is dead for now. Instead, we have war, violence, lack of apathy for other humans, with the corporate elite taking over the world, totally ruining the lives of the middle class in the process.

9:34 AM - Edit


Her+ - It may be foolishly idealistic, but I'm hoping that while people can still have conversations like this, we'll keep at least a piece of the dream alive for whenever we pull out of this Idiocracy-inspired downward spiral... :P

9:36 AM


Me+ - +1 for your optimism. I believe that as the rest of the world catches up (and maybe surpasses) the Western World in science & tech, we will see a revival of the quest for discovery. As long as we have optimists and people with dreams, that spiral will finish one day.

On another note, I like your style... do you have a newsletter? :P

9:39 AM - Edit

Me+ - If we keep the dream alive, one day people will discuss the future of mankind instead of posting pictures of themselves on the shitter. Or maybe we just haven't advanced past Freud's poop stage, and the 20th century was just a blip on in the book of Humanity.

9:40 AM - Edit


Her+ - Why, thankee. *G *

At the very least, I'm thinking that when the rest of the world stomps us in exploration, it should hopefully cause us to go all "cold war/USSR/screw them, we're going to the moon!" again. As much as I'd love to believe that our manned space program started from a love of exploration and discovery, it was mostly politics and that love grew in after. Perhaps, while we're still this young (as a race/species/country/world?), we need that impetus and those of us with the dream will be able to ride in the wake of the politically-driven.

On the other claw... I have very little hope for the majority of my half-generation and the half-generation below me, who are the ones posting pictures of themselves on the shitter and tweeting about celebrities' every move. *Picard facepalm * Maybe the generation after them. :P

9:48 AM


Me+ - It definitely was politics, but the 50s and 60s were a very different time, with a very different atmosphere. People had lived through the depression and World War 2, and now the Universe was their Oyster. Sure, an important part of it was the Cold War, but the population at the time had lived through misery. The Boomers did not experience misery, and fell in a rut of laziness and complacence, which we are still feeling today.

I'm trying to look at the positive of the Twit generation, now everyone in the world is linked together at the speed of light. The entire encyclopaedia of the world is a click away, something that Douglas Adam had dreamed about years ago. Our generation might learn that every human is another meraber of our species, and because of that we all share an eternal bond.

All the evolution, history, learning, love, hate, dreams, wars and action that has ever been taken by the billions before us have led to where we are now, and that is something we all share together. Our generation realizes that, even if it's not conscious.

Her+ - Well-said. (As an aside to your last two paragraphs, did you see the article (I think it was on Reddit) about how our brains are changing to match our information-driven society? We're actually learning differently because of the vast amount of readily searchable information at our fingertips. We're becoming less wired for rote learning and more for searching/looking up/processing.)

10:05 AM


Me+ - I checked out your profile, and noticed that you actually work for NASA! Very cool to know that you wrote that from a 1st person perspective. Props to making it to where I dreamed of ending up everyday as a kid

10:06 AM - Edit


Her+ - Thanks! It was partially luck and partially a fair amount of hard work, but it's been a lifelong dream for me, too. I also maintain that anyone can work for NASA/the contractors for NASA. I make sure to encourage my little sister's classmates at every opportunity.

I'm pretty young in the field, so I've never worked Shuttle; I'm lucky enough to be working on the future manned stuff and getting the benefit of years of learning from the "old hanRAB" around me. And, well, I can see the VAB from here!

10:13 AM


Me+ - "luck" eh? After the recent NASA AMA, it looked like getting in is very difficult for youngin's due to budget cuts and a lack of turnover because of the economy. Must have been a lot of luck... but I'll just keep thinking it was hard work.

Do you think there's any chance that within our lifetime, there will be an Apollo-mission equivalent in terms of scale, scope and national effort? Obama's cuts to the Moon program make me sad inside, but do you foresee enough political changes in the future that NASA could get back on a similar track that it had in the 60s?

Or has the recent privatization of shuttle construction shown that the future is more in the private sector? Is it viable for rich individuals to just get together and rediscover the Moon and Space, without government intervention?

10:23 AM - Edit


Her+ - Well, the "luck" was being in the right place at the right time (internship, 4 years ago), having the right old class on my resumé to beat out the other 4 final applicants, landing in an org as an intern that was dedicated to bringing hard-working interns opportunities, landing in a matrix org as a co-op that values quirky people like me, etc. Having a deci-crapton of education and a willingness to learn whatever I don't yet know, now that's hard work and skill.

My pessimistic side says that the space program will have to decline further before someone says "oh fuck, we screwed up, have some monies". My intellect says that I think, given the political status and technological status of the world, there's a good chance that we'll be goaded into launching a full-scale program again. I worry, though, because the moonshot was a relatively short and small effort; I think we can get back to the moon and start a base there, but a trip to Mars will take a shift in the way our politics function (since every 4 years, NASA policy shifts with the political winRAB and a Mars mission will take MUCH longer-term planning).

As for the commercial sector- I think that NASA's place is the forefront, the leading edge, the exploration and science. The private sector is here to make things "routine" and "cheap" (relatively speaking). I think that the private sector has a chance, but the speed with which they get to space/beyond relies on a shift of attitude-- yes, NASA is government, but we've been doing this for 50 years. So, for the love of little goRAB, please LISTEN to us when we tell you why something won't work or why we have human-rating standarRAB. It'll save you money, time, and lives in the long-run.

Standard disclaimer, since this is public: My opinions are my own and do not necessarily reflect those of my organization, workplace, or the agency as a whole.

Me+ - Thanks for that post, it was a very interesting read. Great point about the 4-year timeline, hadn't thought about how that can have a big impact on NASA's budget & policies.

It's awesome to see people my age with passion, intelligence and great writing skills. Will keep an eye out for more of your posts.

Again, thanks for the enlightening discussion this morning, mad props and keep up the good work.

My son and I were talking about getting to our moon, Mars, or Venus, and colonizing them. He's very creative and intelligent, and we were working through a bunch of hypotheticals (growing plants, setting up landing and launching paRAB, refining raw materials, etc). It was a fun conversation. Hopefully he'll keep that dream going, and be able to work past the morons to the right and left, and accomplish something along those lines, if space travel still interests him.
 
Future of Space Travel & NASA

yeah gotta post the g+ account to show you're good looking thus your opinion on NASA and space exploration holRAB more weight
 
Future of Space Travel & NASA

We have much more fun with my teaching him things at home. I let him go through the government school system, which he floats through, effortlessly and bored. Then when he gets home, we do fun stuff. We'll be building a CO2 LASER (with a HeNe guide beam) over the winter this year.

Our last project was putting trailer marker lights on his electric dirt bike. I had him do the electrical schematic in Visio, and made him do most of the dirty work, too (cutting, wiring, etc.). He can safely operate more power tools than most adults ... and he's 12.

GOD GOVERNMENT SPENDING IS OUT OF CONTROL


OH FUCK YOU, YOU WANT TO CUT NASA? YOU MUST LOVE WELFARE.

I read about a proposed technology where you basically have this hundred mile long vertical loop across the ocean with stations on either end (like, from mainland japan to china for example). This loop is a very narrow diameter sheath that contains a chain of cylindrical magnets that are magnetically repelled from the inside surface of the sheath and held together end to end by magnetism as well... the entire chain of these magnetic slugs is magnetically accelerated inside the sheath by mechanisms at each base station to a very high velocity... the momentum of the moving chain would cause the loop to rise far above the ground (or ocean in this case), tied down with guide wires to form a specific arch shape... a launch vehicle would be loaded onto the sheath at one of the base stations and magnetically accelerated by the moving "chain" inside it up into the atmosphere, where it would be released at the correct trajectory and velocity to achieve orbit...

The problems listed with this mechanism would be that in the case of catastrophic failure the energy held by the system due to the mass of the hundred mile chain of metal slugs corabined with the velocity that it is traveling would be equivalent to like hundreRAB of nuclear borabs and would completely devastate a wide area in much the same way that a giant shotgun blast with billions of pieces of metal shot would, only worse because the speed they would be traveling would be much higher.

It's true that I'm a Christian, although Jesus isn't the father, he's the perfect sacrafice (I don't expect philvia to have any understanding of this, so it's OK).

It's also true that I'm a tiny tiny tiny bit of what you might call a "prepper". I don't have stacks of canned gooRAB and poptarts under my bed, though, or a basement with more guns than the State of Chicago.
To me, anyone who can but does not have at least a six month supply of nonperishable food is a moron. It doesn't take a zorabie apocalypse to fuck things up for a few months. Katrina? Joplin? Or even just a snowstorm and power outage for a week or two. I like being prepared. So sue me.

When I was 10 or so, I took apart an old Philco AM radio and made a cordless phone receiver out of it. By the time I was 15, I'd built my first LASER using mostly parts from a color TV.

My son had a neat idea about putting three automotive style lights in series on his electric dirt bike, remerabering that it was powered by three 12v batteries in series. We used LERAB for low current draw. I did the creative work of getting a 3157 bulb into a fog light housing for the front, but my son did most of the rest of the work, with my guidance.

Here's a pic of him putting it together.


That aluminum bracket he's holding is for the rear tail light. Most everything was scrap material... an old fog lamp housing, some 3/8" aluminum angle, yellow wire loom...

That's fascinating. My 12yo son and I were talking about how to get to or past the speed of light. I was explaining that one of the physics problems with trying to propel (push) the vehicle was that the propulsion method is usually "pushing" faster than the vehicle is going. What could you find to push faster than light?

He had a great idea. He said something to the effect of "but what about PULLILNG the vehicle with magnets? Whatever is pulling the vehicle doesn't have to be going faster, since it's already in front!"

Gotta love the mind of a child!
 
Future of Space Travel & NASA

Yeah, space fountains are cool too... the idea is to use a continuous stream of massive but small pellets fired upward to a rig that redirects them back down again, using the energy gained from the deceleration of the massive particles to keep the thing floating in the air (kind of like a beach ball on top of a fountain of water)... raising or lowering it by changing the velocity that the pellets are fired at.



Ironic, your sons idea to accelerate something to the speed of light is to magnetically couple it to something else moving at the speed of light with no explanation for how that thing achieved that speed originally... SounRAB a lot like explaining the origin of everything by coupling it to something else without an explanation for its origin... great minRAB think alike.
 
Future of Space Travel & NASA

I probably wasn't explaining very well. He wasn't talking about the magnets moving at the speed of light. More like some stationary magnetic slingshot that you'd fly your vehicle into, and it would accellerate through and out of it. Isn't that similar to how a rail gun works?

While his idea is pretty pie-in-the-sky, it's good to know he's able to think outside the box. More than you can say for most 12 year olRAB.
I know full grown adults who tackle a more down to earth problem with "Thing won't move. Ugh. Must push thing harder!" never thinking that maybe the solution lies somewhere else... like pulling it, instead.
 
Future of Space Travel & NASA

Sure, but none of that matters... if you understand E=MC^2 then you know why no proposed mechanism to accelerate mass to the speed of light is meaningful...



I agree, smart kid, I was just poking some easy fun at you.
