About which feeds we should have here:
We didn't decide on which post ratings mean they should be included or excluded from our feeds. I suggest we include all that have equal or greater than median of upvotes and exclude the rest. Any objections? — TildalWave 2 mins ago
ISS laundry clips :))
01:50
@TildalWave I saw the notification and was going to go flag that comment as obsolete, but you beat me to it :)
@Undo we live in a fast world ;)
@Undo another thing about feeds ... we should specify if we want them posted as regular messages, or as "ticker feeds" (shown via a slide-down ticker overlay that periodically appears at the top of the room)
for photos I think the ticker feeds don't make much sense
@TildalWave Or should we just see which ones are higher volume and make those tickers?
@TildalWave Added to the post, have a link to an explanatory document?
@Undo It's not a problem to change as we feel it makes sense at any time, so I think first adding them as regular posts and if they annoy us, we move them to ticker feeds?
01:58
@TildalWave That's what I'm thinking. Removed from post.
> Message feeds: New items from these feeds will be posted into the room like regular chat messages.
> Ticker feeds: New items from these feeds will be shown via a slide-down ticker overlay that periodically appears at the top of the room, and will not be persisted.
Let's just make them normal feeds for now. If they swamp us, they get demoted.
@Undo agreed
@TildalWave I actually think that the normal-QA question could be shown as messages too - they would generate conversation, and there aren't too many.
02:00
done
OK, then!
Nice!
@TildalWave Has RhysW alread sabotaged them, or not?
Are they using unleaded fuel again?
@Undo well they better not be... last two were major disappointments, and to me more so because of the unnatural time of the "day" I was up just to watch them sit on the launchpad LOL
lol
02:05
Good morning everyone :-)
these two are at better times for me
@Hash Morning? Night!
hey @Hash ;)
10:03:30 here.
it's always morning in SE chats ;)
02:05
@TildalWave I forgot.
@Undo in India its morning
It's 22:06:10 here
That's what I love about SE - it brings countries together.
@Undo 7:35A.M lol
Lucky.
4:07 am
02:08
@TildalWave Yeesh.
I'll keep holding on...
Sitting infront of computer at 4 am ? @TildalWave
@Tildal Are you certified to moderate at that hour?
Anyway, I got to go now. Bye, people!
@Undo good night :-)
@Undo There's nothing to "moderate" if nobody's here :P Anyway, take care!
02:12
The site will remains less active after this time
02:29
@TildalWave in the last message you send to me i could see \moderator mode what's that ?
@Hash it's just a joke that I've removed my mod hat and put on a more causal one (it's like with HTML markup, when you end some element with </element_type> )

Galaxy Zoo is a citizen science project that uses volunteers to classify galaxies from the Sloan Digitial Sky Survey as spiral or elliptical. Now the Galaxy Zoo 2 catalogue has gone public, with even more detailed classifications of galaxies, including bars, bulges, spiral arms, and round and squashed ellipticals.

Palladino et al. find 13 new hypervelocity star candidates in the galaxy and find they probably do not originate from the center of the galaxy.

WOW!! :)) That was a big dump of feeds LOL
@TildalWave why don't India launch its GSAT 7 in Indian rockets
@Hash shouldn't you know the answer to that better than us non-Indians? :P
my guess would be it's simply cheaper that way, and since it's not some classified payload, they've decided to piggyback on the dual payload launcher that was available
02:39
@TidalWave i don't know but this is going to be the second satellite that is launched outside India (i think)
Neah, that doesn't sound right, I'm sure there were many more than just two.
India has launched 70 Indian satellites (as of 26 July 2013) of many types since its first attempt in 1975. Satellites have been launched from various vehicles, including American, Russian, European satellite-launch rockets, and the U.S. Space Shuttle.

@JohnB I just wrote a good night story about how NASA saved pretty pennies on a program that was later scrubbed anyway, so they actually wasted bucket loads of pretty pennies first (but that doesn't matter, because we all learned something from it, right? Hehe): space.stackexchange.com/q/1485/49

@TildalWave Do you know German? O_O
@CrazyBuddy Well, I should. I live close to German speaking countries and I had 5 years of German classes, lived there for a short while,... but it's one of those languages I like to forget LOL
OIC ;-)
And wheeeeeerrrrreee's that room owner? (@RhysW.....) :D

@TildalWave join the club! i did it for 5 years, forgotten most of it xD
@CrazyBuddy messed with Tildal waves (i presume) feed changes, waiting for the ban hammer to smite me :P
Can someone please remove this guy's privilege? He's doing nothing :P
technically they could very easily do so, in under 10 seconds too :P
see :P
its like manish hangs around waiting to collaborate with us on jokes :P
Nah, the tab was open and I saw some activity :p
hehe what's going on here? can't I turn my back not even for a minute?
Well timed humour then!
@TildalWave Don't say such an awful word when you're the mod ;-)
14:40
im claiming half your success tildal :P
@RhysW I still keep it in my CV tho, because it looks better if you speak many languages :P
@TildalWave haha i do not, incase they start talking to me id be caught out very quickly!
@CrazyBuddy There's 3 of us... and in chats, all SE mods are, well, mods
@TildalWave Nah... you're special (being SE.SE's mod) :D

@RhysW went to Germany a few years back for xmas and I was fine ... my accent went a bit more towards the Austrian one, so half of the folks looked at me a bit funny, but yeah ... not really a problem
@TildalWave languages are not my strong point, always been my weakness so i forgot what little i knew very quickly
So, what do you people discuss in our chat session?

well, we have a graphic with lasers
@TildalWave it's happening!
@JohnB ah cool
@JohnB Wooo, yeah! Bunch of guys standing around with hard hats on, yeah!
@DavidFreitag :D
@JohnB Anyway, should be pretty cool. Got it up on the big projector. The helicopter is probably being displayed at full size
@DavidFreitag o_o where are you, an IMAX theater??
17:10
@JohnB A big, for the most part, empty building with large white walls.
ah, nice :)
@JohnB With probably a $23K projector to play with.
@DavidFreitag is it the kind you need to wear body armor to change the bulb?
@JohnB I hope not
heh
*adjusts his 17" monitor*
I am envious
17:13
Yeah It's pretty cool. The guys are about 6' tall on the wall. I also just happened to have a set of really nice speakers laying around. Should be pretty awesome given the overall emptyness of the facility.
@JohnB Wanna spam TL with our events a bit? Let's see if we can get more folks here
drop them the post from meta of the launch ;) (then run LOL)
I'm not sure what's up with that weird paint, the camera doesn't seem to like it much
my boss keeps buzzing in and out and looking at something on my screen, go away dammit I am trying to slack off
@JohnB lol, it would be hard to miss me slacking off :]

Homemade rocket fuel + megablox = homemade rockets.
There is an endless amount of things you can do with potassium nitrate.
1.2 million pounds of rocket though... you would need a lot of potassium nitrate to lift that.
at least two bottles
didn't hear ... when did he say the new t-0 is?
17:42
18 something something
@JohnB that's the age of consent :P
What's with the smoke coming out of the rocket boosters?
I always thought they were bleeder valves, but aren't they using solid fuel?
@DavidFreitag that'll be water/steam/condensation
cooling?
@RoryAlsop For what? Or rather, from what?
@DavidFreitag they're cryo boosters, probably just pressure valves?
17:44
18:03:00 if i heard correctly..
so this is about T-19 minutes, yes?
yep
@RoryAlsop yep
excellent - will get the kids up here as well
I have a web meeting at that time, dammit.
...I can multitask
it's the 1st stage oxidizer (LO2) tanks
17:46
T-4..???
pushed to 11:03 a.m. PST, so +13 minutes on the first launch window
@TildalWave So the smoke is just water vapor?
@DavidFreitag yes

#NROL65 is set to launch this morning at 10:52 am PDT on a #DeltaIV Heavy. Here's a cutaway view of the Heavy: http://ow.ly/olnKT

Oh i see, they aren't solid rocket boosters. That makes sense.
@JohnB Nothing less than what i would expect though

Q: What is the vapour/smoke that comes from the rocket boosters?

Rory AlsopWhile a rocket is waiting on the platform during the final countdown, many of them seem to have clouds of steam or something similar escaping from the boosters. Is this normal, and what are these clouds?

:-)
question stealer!
hahahahahahaha - might be
@RoryAlsop Thought someone would ask it :D
I waited a while to see if you were going to ask it @JohnB
17:50
@RoryAlsop Thank you sir.
@RoryAlsop ;P
(Didn't really expect you though)
@CrazyBuddy I am waiting for my TomTom to update in one window, have the main screen open for the launch and was twiddling my fingers @CrazyBuddy
bored searching through 11000 photos from the Tough Mudder to find any with me in
@RoryAlsop wanna write the answer down as well? it's the LOX/LH2 cryo stages and that's the LOX oxidizer forming water vapor
Although if they are cryogenic boosters that means that they are being filled (or have been filled) with liquid O2 and H2, that is probably a bleeder valve letting off pressure as the tanks warm up
17:52
@TildalWave what, and take both sets of rep?
@RoryAlsop you've been idling around lately, you need them :P
although, I think that's my Space rep just overtaken my SU rep - yay!
Key to earn rep. score in Space.SE --> Google well enough :)
(That applies to most SE sites I think) :D
@TildalWave I was busy - I had a trip to India, then a holiday, then a gig, then a race - only just back to normal now
@CrazyBuddy true
@RoryAlsop I know ;) Still.. rep's a good thing, no?
17:54
@RoryAlsop India... Where?
@TildalWave yarr - in general :-) I'll start typing up an answer now then (hard taskmaster)
And, who's there? :D
@CrazyBuddy Delhi, Mumbai and Bangalore
in one week
visiting some of my team
just to see how they do things over there
@RoryAlsop What..??? You should've visited Manish & Sathya :P
@CrazyBuddy Didn't see anything outside airport/taxi/hotel/taxi/office/taxi/airport
17:55
(Me --> I'm quite anonymous) None can find me :D
was crazy
@RoryAlsop Every chat room I visit --> someone says my name each day :)
Go, Go, Go, Go, Go, Go, Go...
sup @Chris!
Will you please GOooo..???
@Chris & @called2voyage sorry for that message, I thought since you were pinging each other with "what's off-topic regarding private launchers", you might rather see an actual liftoff that's kinda related LOL
17:58
@JohnB (Sigh) He comes & goes... comes & goes... & again -- the same :D
@TildalWave Thanks, I forgot it was launching now.
yo @JohnB
@TildalWave no problem
@called2voyage no problem, glad you're aboard ;)
Anyone know why they start with igniting the starboard booster, followed by the center + port?
BTW while you're all here...

that's tomorrow at a few hours later time
18:00
@Chris should be a question...
@RoryAlsop More rep for you.
@RoryAlsop agreed
I won't be offended if you get around to posting it before I do
@Chris in case of failure, I'd guess... but might be different for various platforms
@Chris I'm vaguely writing the answer to this other one while watching the live feed...
Here we go....
@PearsonArtPhoto: You really missed the rocket :P
18:04
LOL.
I actually heard about it at work just a few minutes ago. Didn't hear if it was successful.
I think SpaceX is the next launch out of Vandenburg. That will be one to watch. Too bad I'll be too busy to watch it...
@PearsonArtPhoto Go now..!!!! Fast... Watch the rockets show their back :)
4475 pounds per second.... 2.5 tons of propellant burned per second... insane.
nice separation
telemetry data is a bit scarce this time, I guess they don't want us to calculate its orbit LOL
@ManishEarth Gotcha :D
lol, well, it is a reconnaissance satellite
18:10
That is a big rocket...
I love the hydrogen flame just before lift off
@called2voyage indeed ... but the last ULA launch about 2 weeks ago had a lot more telemetry and it was also a navy communications satellite
@TildalWave MUOS, right?
In that case it was already pretty obvious where it was going :P
communications != reconnaissance, unless I'm misinterpreting you.
Orbits for comm satellites aren't that big of a deal. Orbits for recon are.
Comm satellites are going to stay in fairly predictable orbits for the most part.
18:12
@PearsonArtPhoto Exactly.
In any case, the amateurs will have this orbit pinned down, just give them a couple weeks
gotta go, bye people
Recons change their orbits a bit from time to time, so everyone doesn't cover their bases before being visited.
@Chris Hold up, what change do you recommend to my post?
@Chris hmmm you know I don't remember any more LOL... WGS6 methink? Tho that'd make it for Air Force
Okay... gtg everyone... c'yall later ;-)
18:15
@Chris okay Chris - I'll do it now
I wish I knew there was a discussion of the launch here or I would have been here and watching.
@Chris It's a good question. I would have thought they would start with center and then ignite port and starboard together.
@called2voyage FWIW I think it's OK in that "department" you two had a discussion in the comments, but it does seem a bit too broad and speculative. I think if you described which exact implications you had in mind, it might make it automatically also more appealing to this site, dunno.
@TildalWave That is a good point. I'll expand a bit on what kind of impacts I'm considering.
@TildalWave How does it look now?
18:31
@called2voyage Looks better, but it's not really my area so from a semantical point of view, I just dunno. :) I'd also quote a few most relevant excerpts from that news article, to avoid possible future link rot problems. And it might help your question further to be more within scope (if there's some too lazy to click on the link LOL) ;)
@called2voyage maybe also try and find a few more tags it relates to... we should have some, like e.g. "funding"
@called2voyage And I think this was a good advice from @Chris:
so maybe phrase it in a way that discusses the impact to operations in space, rather than the disposition of the contractors who maintain it. — Chris 42 mins ago
Anyway, I'm deleting those comments they're kinda obsolete now
18:51
@RoryAlsop I've posted the answer to the odd booster ignition order question.
@called2voyage Makes sense. I wonder what causes the difference in effect between cape canaveral and the west coast. I could only imagine temperature humidity altitude or some combination of those factors that causes the fireball effect to be bigger.
 
3 hours later…
21:33
@called2voyage if you wanna edit in your ignition sequence answer, I've found two nice pics:
it's also explained in the space.com article
and a cool video of SSME (Space Shuttle Main Engine) & Booster ignition in slow motion:
related article is here
22:00
@TildalWave that is extraordinarily cool
It is, isn't it ?:) You have to first watch the slow motion one and then the normal speed one immediately after.
it's in that article I linked under the video
@DavidFreitag I have a feeling it might be due to differences launch facilities themselves, but that's a guess
re: my comment on giving the amateurs a couple weeks to pin down the orbit... apparently one of them caught it on its first orbit!
A Boeing Delta 4 launched an NRO spy satellite into polar orbit Aug 28. Congrats to Cees Bassa who spotted the satellite on its first orbit
it'll still take some time to refine the orbit but usually it's a few days before they can even spot the thing
22:29
@Chris I spotted some satellite reboosting a few hours ago ... pretty big and visible burn but only for maybe 2 seconds ... must have been relatively low, but definitely not just some airplane, it was going way too fast way too high up. Heading North to South, about 10-15 degrees longitudinal inclination
@TildalWave very cool
@Chris tell that to my missus she's making fun of me I moderate space too much LOL
but she saw it too
@TildalWave I know the feeling :P
It's really clear skies here, just after the rain ... I'll try to set the cam to do long exposure sweeps around zenith, see if it can put something on film ;)
