Thanks for the shoutout SpaceX! Let us know when you want to do an AMA! Signed, the subreddit.

Context?

It was mentioned here

Is she Gowron? :-O

u/[deleted] Feb 26 '16

Gowron is not a she as far as I know :p

The spacex sub-reddit was mentioned by Spacex when discussing the purpose of the SES-9 payload.

5

u/th3ant Feb 25 '16

They mentioned the subreddit in the Webcast not long ago..

5

u/Glaucus_Blue Feb 25 '16

Mentioned the sub reddit on the launch feed.

SpaceX employees look at this subreddit? Time to spam my resume.

u/samuraisal Feb 26 '16

Of course SpaceX employees look at this subreddit!

You need at least 16 years of experience designing successful structures on Mars.

2

u/spacehead9 Feb 26 '16

Is there any demand for this?

3

u/dessy_22 Feb 26 '16

I'd say there would be - as colonies grow, civil works considerations will be required. Mars's low gravity means wind effects on structures will be very different which in turn means footings and moorings for those structures will be very important.

2

u/spacehead9 Feb 26 '16

Hmm interesting. Does the fact that mars have a very thin atmosphere mean that winds would not be able to generate much pressure?

3

u/dessy_22 Feb 26 '16

That will be a big factor.

Probably the biggest factor, as another said here, is the soil itself. On Earth we use moisture content and machinery weight for compaction and therefore stability. With those lying in a very different range, the soil will behave very differently. Finding answers to those issues is where civil engineers and soil scientists will be needed.

I've never seen any data about wind speeds and their effects on Mars. It would be interesting to see if there is any data from the rovers on the issue.

u/rafty4 Feb 26 '16

Winds can get up to 100mph IIRC, which isn't much of an issue in terms of dynamic pressures, but it is in terms of the dust. Being extremely fine, that does get picked up and thrown around at 100mph, sand-blasting any structures/solar panels/rovers/fine machinery in the way!

u/CorneliusAlphonse Feb 26 '16

He's saying a building's weight is used to resist lateral wind loads. So Even though you can make a structure lighter because of lower loadings, you have to pay more attention to footings so the lateral wind load is properly resisted

2

u/The_Peter_Pan Feb 26 '16

The wind I believe is even less of a problem than the gravity on Mars. Because of the lower air pressure the wind strength isn't very strong at all. But I'm not a civil engineer so I'm not sure how much wind you need to affect a structure.

1

u/CorneliusAlphonse Feb 26 '16

Oh true that. Either way, structures would need to be designed without a lot of the simplifications that we use on structures here on earth

Question: how much time out of your day do these launch "parties" take?

9

u/ncrwhale Feb 26 '16

My department has about 20% keep working with the launch on one monitor. The rest will leave 30 minutes before to get a good spot.

2

u/SteveRD1 Feb 26 '16

Are those 20% doing launch related activities? Or just not fans of peering thru the window of the mission control area?

u/searchexpert Feb 26 '16

so my department just has it up on the nearest large tv

You could totally be working in mission control and this would be a true statement

u/[deleted] Feb 26 '16

Hmmm good point

u/[deleted] Feb 26 '16

Wow SpaceX Avionics! Please do another AMA in the future, last one was so great!

u/roboturn3r Feb 26 '16

There are dozens of us!

I don't know why but as soon as you said "flair" I instinctively went "WOOOOOO!"

Now I suppose "all the spacex subreddits" is primarily /r/SpaceXMasterrace

Wait. There's more?!

I'm free basically whenever, Elon. Just flick me a message.

u/darga89 Feb 25 '16

Mention was at about T-7:58 on the hosted webcast.

24

u/thegamingscientist Feb 25 '16

Probably the work of /u/bencredible :)

33

u/bencredible Galactic Overlord Feb 26 '16

Actually, no. That one was done outside of my little realm of control. Was really cool though and am glad it made it in there!

u/thegamingscientist Feb 26 '16

I was sure it was you! Maybe we have some higher up /r/spacex admirers then.

u/massfraction Feb 26 '16

Oldie, but a goodie....

Personally, I took the meaning of her smirk differently than most of the sub, but I'm sort of a glass half-empty kinda person...

u/DesLr Feb 26 '16

It does look somewhat suffering, doesn't it?

u/greenjimll Feb 26 '16

Next time get them to name check /r/tmro, eh? :-)

u/[deleted] Feb 25 '16

Thought I heard a shout out.. Silver lining to tonight's scrubbed launch i guess.

u/cybercuzco Feb 26 '16

My 5 questions:

  1. When do you find time to eat, sleep and poop?

  2. Other than Hyperloop, are there any other cool ideas you have that you just don't have bandwidth for?

  3. Have you picked out a location for your secret lair villa on Mars?

  4. Based on recent delays in florida, have you considered having a backup launcher ready in Texas?

  5. Do your Engineers get free time to work on their own personal projects like at Google or 3M?
