I’m bored and am on my way home before the holiday festivities begin. As such, anyone who has any questions about Aerospace, it’s history or development.
Source: I work in the aerospace industry.

Have a nice day.
Have a happy holidays!

Are spaceplanes going to replace rockets for LEO missions in the future?
NationalAeronauticsAndSpaceAdministration
Yes, specifically SSTOs. They are capable of launching from more locations & require less servicing & assembly to use.

What do you think about ol' musky?
NationalAeronauticsAndSpaceAdministration
Great forward force in the industry. He will likely burn himself before he can create half of his claims. Do trust he’ll work towards Mars.

Why do my kids want snacks so often?
NationalAeronauticsAndSpaceAdministration
Because they’re great!
AFloridianThatAlwaysUpvotesCanada
Former child here. Snacks are great, but the best snacks are definitely the ones that you were just about to eat.

Can you believe we dismantled the shuttle program with no alternative in hand, so no we need the Russians to take us to the ISS?
NationalAeronauticsAndSpaceAdministration
We *did* have a replacement as early as the 2000s. It was called Constellations but it was cancelled as it was ‘too costly’.
felinegratificationprovider
What do the Russians have in space?
NationalAeronauticsAndSpaceAdministration
Used to have stations. Have lunar rovers and proves. Sent stuff to Venus. Lots of stuff.

Why is space Black?
NationalAeronauticsAndSpaceAdministration
Because it’s the absence of matter. Where there is no matter, there is no color.
badcommenter
How many space?
NationalAeronauticsAndSpaceAdministration
Many much.

Is my dog a good boy?
NationalAeronauticsAndSpaceAdministration
Houston, we have a good boy.

What are the real chances of micro asteroids impacting interplanetary travel vehicles?
NationalAeronauticsAndSpaceAdministration
Moderate. It’s more likely to happen if we try to pass through the Kuiper belt.
DaPuddinMan
How accurate are the detection methods?
NationalAeronauticsAndSpaceAdministration
We’ve located around 10% of the small asteroids (few meters in size), smaller the object, the harder to spot before hand.
joshuNoodleDriver
Will we be able to produce artificial gravity in space by putting spacecraft into a tumble during travel, or is that more fiction than fact?
NationalAeronauticsAndSpaceAdministration
Already did generate a ~hundredth of a G during a Gemini mission. So it’s feasible. Just heavy for larger structures, therefore expensive
irrelevantInPerpetuity
What do you do for the aerospace industry, specifically?
NationalAeronauticsAndSpaceAdministration
Term on the door is Flight Director. I write the technical documents, operations,& hierarchy for mission control & command it during launch
TheTittyLicker
Cool
irrelevantInPerpetuity
Wow, yeah, that is genuinely cool! I wish I had a more intelligent question to ask you, but all I have is this: do you play KSP?
TheTittyLicker
I think you replied to the wrong comment im just a humble programmer. But yes i have and its the shit
AFloridianThatAlwaysUpvotesCanada
Is Deep Impact plausible? Like landing on a giant asteroid hurtling through space and bloing it up?
NationalAeronauticsAndSpaceAdministration
We’ve landed on a meteorite already, so yes. Sure, we can blow it up, but warranting enough notice, there are far better alternatives.
ZombieJonSnow
Like a gravity tether? Or is that just more impractical theory
ZombieJonSnow
How many aliens are there?
NationalAeronauticsAndSpaceAdministration
We have searched the furthest edges of the universe for life. We’ve even looked on Earth. There is absolutely no intelligent life on Earth.
ZombieJonSnow
What about dummy aliens?
NationalAeronauticsAndSpaceAdministration
Still more intelligent than some humans!
DailyBullshit
What do you think about the Inflation model of cosmology?
NationalAeronauticsAndSpaceAdministration
I support it. We are getting more distant from other objects in the universe.

Thank you for everything you do.

You’re welcome fellow Imgurian!
canipleasejusthaveanameforonce
If your oxygen tank gets punctured is there any backup or are you doomed, and also what are effects apart from suffocation
NationalAeronauticsAndSpaceAdministration
Depressurization will kill you first.
canipleasejusthaveanameforonce
Not quite sure what that is
NationalAeronauticsAndSpaceAdministration
Its when the ambient level of atmosphere drops to a point where the moisture in your body boils & solid mass in your body freezes to ice.
canipleasejusthaveanameforonce
ah ok, thanks for answering
solidsnuke
Is there really a viable alternative to rockets at this time? Not space elevator stuff but something that can make us go faster...
NationalAeronauticsAndSpaceAdministration
Not really. Closest is air launching equipment but the margin for mass is much smaller and still requires rockets.
solidsnuke
Thanks
NationalAeronauticsAndSpaceAdministration
You’re welcome fellow Imgurian, and happy holidays to you!
solidsnuke
Happy Holidays to you too spaceman
Iammetatron
Will cold fusion ever make deep space travel possible? Follow up: what would it take to make artificial gravity?
xmaneds
the simplest artificial gravity is just to make a space station rotate; the inertia and "centrifugal force" will feel exactly like gravity
NationalAeronauticsAndSpaceAdministration
Eventually, yes. Issue is power requirements being so steep. AG is possible as has been proven. Just will be heavy for larger structures.
xmaneds
do you have any comment whatsoever on FTL travel, warp drive, etc? wormholes or anything? or is it permanently ruled out?
NationalAeronauticsAndSpaceAdministration
All hypothetical as of yet, but there’s hope for space-time warp. Specifically the Albeirre drive (butchered the spelling).
Fluffydeathkitten
Would it be possible to use the gravity slingshot with Earths gravity when going to Mars?
NationalAeronauticsAndSpaceAdministration
You wouldn’t be traveling fast enough to get a slingshot from the Earth if you Launch from the Earth. You’d simply escape Earth’s gravity.
Fluffydeathkitten
Second question: how far from earth would you have to go for it to work if you would try to use to get mars and would help at all ro no?
NationalAeronauticsAndSpaceAdministration
You’d have to be traveling at faster than orbital speeds as soon as you enter Earth’s SOI. Could it help? Sort of. Better to just go direct.
RubberChickenTenders
How far away do we think we are from a man on mars? (In your opinion)
NationalAeronauticsAndSpaceAdministration
Less than 15 years. Possibly within 10. All weighs on Mr. Musk not burning himself out too early.
superkingthebestoneofthethree
When, if ever, do you see a person being put on any other planet?
NationalAeronauticsAndSpaceAdministration
We could send humans to the upper atmosphere of Venus. Developing technologies for it. When will we land? Mars in 10-15 years.
superkingthebestoneofthethree
Does the asteroid belt make it an absolute no on going any further out?
NationalAeronauticsAndSpaceAdministration
Not without better protection. But you can avoid the belt by navigating around it. Just costs more fuel in the long run
xmaneds
How can TIE fighters fly in the atmosphere? Their wing shape is okay for space (no air) but horrible aerodynamics in an atmosphere.
NationalAeronauticsAndSpaceAdministration
Sci-fi something something.
xmaneds
like the B2 bomber to the extreme:"The B-2’s unique shape makes it unstable, and it relies on a computer to stabilise it and keep it flying"
NationalAeronauticsAndSpaceAdministration
Probably.
NaelBow
Do you give out christmas card with space facts written on them?
NationalAeronauticsAndSpaceAdministration
I should.
IPostAboutPoliticsIfYouDontLikeItSuckIt
How much time do you spend faking all the pictures of Earth to make it look round? And why? (s/)
NationalAeronauticsAndSpaceAdministration
Because we have to keep the Space potatoes to ourselves!
IPostAboutPoliticsIfYouDontLikeItSuckIt
OK, serious question: Is the whole flat Earth thing really annoying? Or amusing? Or somewhere in between?
NationalAeronauticsAndSpaceAdministration
Initially I found it stupid but those who actually think are good; skepticism is good. Check sources. Denialism is terrible & crap.
Greymalum
Have you ever hid a body on board a rocket? Would you be willing to help me try?
NationalAeronauticsAndSpaceAdministration
You really don’t have room to. If there’s not fuel there, there’s payload. Plus mission control knows everything. Including the body.
Greymalum
I can wrap it and remove the fluids to lighten the load. I assume I am not convincing enough. How's twenty bucks?
NationalAeronauticsAndSpaceAdministration
How about you just launch one finger at a time?
Greymalum
That does seem time consuming. Likely tissue breakdown will be severe and smelly before I finished. Plus I hate chopping, it's messy.
NationalAeronauticsAndSpaceAdministration
Best I can suggest is to leave it under the rocket. The exhaust will vaporize it.
Geniefromdownunder
Can I have some space?
NationalAeronauticsAndSpaceAdministration
Sure! If you can get to it.
Geniefromdownunder
Mate, if I can't get it from my wife and kids, I can't get it from out there.
NationalAeronauticsAndSpaceAdministration
Harsh... hm. I see your predicament. Invest all your money in SpaceX. You’ll get your money back and more.
superkingthebestoneofthethree
Spacex is privately held :(
NationalAeronauticsAndSpaceAdministration
When they open stock, then buy in.
TheNerdFonz
Is it possible to calculate the death of a black hole? If so is it based on when the available matter within its event horizon has been...
TheNerdFonz
exhausted? Or does a black hole of a certain size need to consume X amount of matter before ending? If so, can you run calculations on all..
TheNerdFonz
...the mass in the vicinity to determine how long it’ll take? Or are black holes truly eternal? Never to end, only to grow and merge into...
TheNerdFonz
one another as binary black holes?
TheNerdFonz
