[09:02] <fsphil> boo silly wind: http://habhub.org/predict/#!/uuid=ffa4f777fc5b1314eb902ef8eb1ec09aac0c6304
[09:02] <Randomskk> I wonder if we can get surface current predictions for payloads lost at sea
[09:03] <jonsowman> probablu
[09:03] <jonsowman> *y
[09:03] <fsphil> that'd be cool!
[09:04] <DanielRichman> do the noaa have the data you'd need to do that
[09:04] <Randomskk> the dataset we use has /so much/ data but I'm not sure if it has currents, let's see
[09:07] <Randomskk> ...no, not in GFS
[09:07] <Randomskk> it does have the surface water equivalent of accumulated snow depth though
[09:07] <jonsowman> lol
[09:07] <Randomskk> http://nomads.ncep.noaa.gov:9090/dods/ GFS isn't the only dataset though
[09:08] <Randomskk> http://nomads.ncep.noaa.gov:9090/dods/wave
[09:08] <Randomskk> surface none primary wave direction [deg]
[09:08] <Randomskk> surface none secondary wave direction [deg]
[09:09] <Randomskk> :o
[09:09] <jonsowman> hehe
[09:09] <Randomskk> http://nomads.ncep.noaa.gov:9090/dods/wave/nww3/nww320110516/nww320110516_00z.info
[09:09] <Randomskk> global wave model forecast
[09:10] <Randomskk> wow, it really does have it
[09:10] <Randomskk> well, waves and such, anyway
[09:11] <DanielRichman> you'd need wave, tide and currents?
[09:11] <Randomskk> I think wave velocity of some kind might be useful but then it does have height and period
[09:11] <Randomskk> dunno what would affect it most
[09:12] <jonsowman> shall we just not launch payloads into the sea if we want them back? :P
[09:12] <Randomskk> I don't think mid ocean currents are all that well understood
[09:12] <Randomskk> remember when a shipping container of rubber ducks got loose?
[09:12] <Randomskk> and they used where the ducks turned up to help work out ocean currents
[09:12] <Randomskk> jonsowman: pffft
[09:12] <jonsowman> oh yea I remember that
[09:12] <jonsowman> :D
[09:12] <Randomskk> make them IP67 rated and floating and you'll be fine
[09:12] <jonsowman> haha
[09:13] <Randomskk> solar panel, SPOT
[09:19] <fsphil> could probably run a spot from the wave motion

[12:00] <Ikarus> much better ways to watch it
[12:01] <NigeyS> true
[12:01] <NigeyS> unless my sums are wrong i got 13.7Gbps
[12:01] <Darkside> wow
[12:02] <NigeyS> thats a shit load of b/w lol
[12:02] <Darkside> how much b/w for the stream?
[12:02] <NigeyS> i think hd is about 600kbps ?
[12:02] <Darkside> heh
[12:02] <Ikarus> http://www.nasa.gov/178952main_Mission_Audio_UP.asx 1200kbps stream

[12:03] <NigeyS> 1200 :o
[12:03] <Ikarus> that is the 1200kbps one
[12:03] <Darkside> Ikarus: whats the highest res screen you know of?
[12:03] <Darkside> stream*
[12:03] <NigeyS> oh dam that's nice lol
[12:03] <Ikarus> Darkside: highest res probably that one aswell
[12:03] <Ikarus> 640x480 :(
[12:04] <Darkside> ustream is higher res
[12:04] <Darkside> im sure
[12:04] <Ikarus> higher res isn't on the internet afaik, only on satellite
[12:04] <Darkside> it looks pretty damn nice on my 24" monitor
[12:04] <Darkside> esp when its fullscreen
[12:04] <NigeyS> meh :( me and my lowly 21"
[12:04] <Ikarus> Darkside: yes 720p is on the satellite stream and some US cable providers
[12:04] <Darkside> Ikarus: look at ustream
[12:04] <Darkside> it looks *really* nice
[12:04] <Ikarus> Darkside: it's a proprietary app, I just want to use my normal media players
[12:05] <Elwell> yeah, wish ustream worked in vlc
[12:05] <Darkside> its still higher res
[12:05] <Darkside> and goes fullscreen
[12:05] <Darkside> and looks absolutely magnificent
[12:05] <Darkside> i think its a 720p stream
[12:06] <Elwell> *wish* they'd stick a feed on a european satellite
[12:06] <NigeyS> yeah its not fair they dont do a eu broadcast :(

[12:17] <NigeyS> wouldnt it vibrate the pad apart if they didnt use it, or something along those lines ?
[12:17] <LazyLeopard> as in last Weds, or day after tomorrow?
[12:18] <jcoxon> this weds
[12:18] <LazyLeopard> ...and how did Saturday's flights go? Any of them stuck up trees?

[12:18] <NigeyS> ohh
[12:19] <NigeyS> friend of mine went to launch a few years back, said even 3 miles away at the visitor center you could feel the heat from the srbs
[12:19] <Elwell> last one went off evenening before I arrived there :-(
[12:19] <NigeyS> ah dam, hows that for bad timing :(

[12:23] <Elwell> have they got funding for the last one?

[12:24] <Hibby> shame. If it was July, I'd make an effort to go see
[12:24] <NigeyS> i think its been delayed to july
[12:24] <NigeyS> depends on the condition of the pad after this launch
[12:24] <Hibby> \o/

[12:49] <Hibby> did I ever post the 45 minute slow mo video of the shuttle launch?
[12:49] <Elwell> that the nasa one from all the angles?
[12:50] <Elwell> see also 'in the shadow of the moon' for stunning video footage
[12:50] <NigeyS> 76,000 viewers .. ffs ...lol
[12:50] Action: Laurenceb_ plays the space launch music for james bond you only live twice
[12:50] <russss> NigeyS: yeah and that doesn't include the NASA flash player, I don't think
[12:50] <Elwell> pfft. somafm.com/missioncontrol :-)
[12:50] Action: Hibby plays the final countdown
[12:50] <NigeyS> oh
[12:51] <SpeedEvil> hey!
[12:51] <russss> last launch had 150k viewers on ustream
[12:51] <SpeedEvil> No fair.
[12:51] <SpeedEvil> I was about to do the final countdown joke.
[12:51] <Laurenceb_> theres covers on the rcs engines
[12:51] <SpeedEvil> Is htere another built-in-hold?
[12:51] <NigeyS> lol speedy
[12:52] <NigeyS> nope
[12:52] <Hibby> lol
[12:52] Action: SpeedEvil wonders why he thought there was one at 3:00
[12:54] <Laurenceb_> actuators work.. thats kind of good to know
[12:54] <SpeedEvil> Yeah.
[12:54] <SpeedEvil> Trying to steer it by weight-shift is annoying.
[12:54] <NigeyS> lol they do kinda help
[12:54] <Elwell> gotta admit, that's *lovely* video
[12:54] <Darkside> Elwell: watching ustream?
[12:54] <russss> SpeedEvil: I think 3:00 is a possible hold point
[12:55] <NigeyS> those birds need to go away or get toasted!
[12:55] <Darkside> russss: we're at 2 min
[12:55] <Darkside> well, less
[12:55] <russss> in fact I think T-3 is the latest possible hold point
[12:55] <Darkside> 1:30
[12:55] <Elwell> cern is the same res, and marhinally faster
[12:55] <russss> anything less than that will trigger a recycle to T-3
[12:55] <SpeedEvil> ah
[12:55] kd0mto (~dago@12.163.240.19) left irc: Quit: AFK, I'm IRL now.
[12:55] <Elwell> may as well not kill the external links :-)
[12:55] <russss> (but they can only sit there for like a minute because of LOX drainback)
[12:55] <Laurenceb_> resolution is awesome
[12:55] <SpeedEvil> The SRBs launch at T-0:03?
[12:56] <SpeedEvil> light
[12:56] <Elwell> 0
[12:56] <russss> SRB ignition is T-0
[12:56] <SpeedEvil> ah
[12:56] <Elwell> main engines at -3 secs
[12:56] <SpeedEvil> Makes sense on reflection.
[12:56] <Ikarus> lol
[12:56] <Ikarus> CNN is 40 seconds behind
[12:56] <Ikarus> webstream 80
[12:56] <Elwell> srbs are 80% of thrsr
[12:56] <russss> main engine start is T-6.6, to be picky :)
[12:56] <russss> although they ignite ~300ms apart
[12:57] <Darkside> nice roll
[12:57] <Elwell> straight into cloud
[12:57] <SpeedEvil> Argh - missed it - it went and did the buffering thing.
[12:57] <Elwell> now I see why the UK doesn't have a space programme :-)
[12:58] <Darkside> theres the 400" lens
[12:58] <SpeedEvil> Wow - the tank moves hugely at maxQ
[12:58] <SpeedEvil> The UK does have a space program.
[12:58] <SpeedEvil> IIRC 30 million funding?
[12:58] <Darkside> pretty
[12:58] Action: SpeedEvil tries to remember.
[12:59] <Elwell> SpeedEvil: yeah I know, just being smartarse
[12:59] <Ikarus> SpeedEvil: yup, but no man in space program
[12:59] <SpeedEvil> I know.
[12:59] <russss> woah, sparkly
[12:59] <SpeedEvil> Awesome.
[12:59] <SpeedEvil> I guess that's looking through the turbulence.
[12:59] <Elwell> 'sailing into fair winds' -- I'd hope not in space...
[13:00] <SpeedEvil> Solar winds.
[13:00] <Ikarus> SpeedEvil: nah, that was focus tracking lsot
[13:00] <SpeedEvil> Though affected by the ionosphere at that time.
[13:00] <SpeedEvil> Ikarus: hmm. Maybe.
[13:00] <SpeedEvil> Ikarus: It looked focussed.
[13:01] <Ikarus> it didn't to me
[13:01] <russss> the focus on those long-range cameras is telemetry-controlled IIRC
[13:01] <SpeedEvil> The dots looked focussed.
[13:01] <Ikarus> russss: yup, so if there is a small bit of interference on that signal
[13:01] <Ikarus> I'd bet it's analog
[13:01] <Ikarus> that gear is ancient enough for it
[13:01] <russss> I think they upgraded all that stuff after columbia
[13:01] <SpeedEvil> Analog? Naah - a steel cable.
[13:01] <fsphil> viewer count dropping steady
[13:02] <jonsowman> #.
[13:02] <jonsowman> damn you ssh
[13:02] <Elwell> I saw 111k - what was the max?
[13:02] <Laurenceb_> attitude control is _slightly_ better than sacex
[13:02] <Elwell> nice roll shadow

[13:03] <Hibby> thats analog distortion on that camera
[13:03] Action: SpeedEvil ponders home-grown solar again.
[13:03] <Elwell> ha, even the DG missed the launch
[13:04] <NigeyS> lol
[13:05] <Darkside> woah
[13:05] <NigeyS> pretty
[13:06] <Laurenceb_> rcs blasts were awesome
[13:06] <Ikarus> oooh, pretty
[13:06] <Laurenceb_> tanks on its own now
[13:06] <Hibby> we're experimenting with replacing rcs thursters with spinning wheels for our cubesat projects @ strathclyde
[13:06] <Hibby> is pretty cool
[13:07] <Ikarus> Hibby: rcs thrusters on a cubsat, tsk tsk
[13:07] <Ikarus> also yes, reaction wheels are a common solution
[13:07] <Ikarus> though I'm still considering magnetic
[13:07] <SpeedEvil> I wonder how much that ice weighs.
[13:07] <Hibby> Ikarus: we're not thrown one up, but we seem to be fairly central in the ukube project
[13:07] <SpeedEvil> A quick test I did in the kitchen indicates magnetorquers are quite plausible.
[13:08] <Hibby> there's also a couple of phD's in novel de-orbiting methods
[13:08] <Laurenceb_> Hibby: do you use an imu?
[13:08] <Ikarus> SpeedEvil: hehe, indeed
[13:08] <SpeedEvil> Hibby: Novel de-orbiting? Do you use an ablative dust-jacket?
[13:08] <Ikarus> SpeedEvil: solar sail deorbitting should also be an option :)
[13:09] <Hibby> don't ask me, I'm just that radio guy

[13:09] <SpeedEvil> Ikarus: At LEO - with small payloads - simple drag is quite high.
[13:10] <Ikarus> SpeedEvil: yup
[13:10] <Ikarus> SpeedEvil: but I was thinking MEO and above
[13:10] <Ikarus> SpeedEvil: stupid idiots and their graveyard orbits are harmful
[13:10] <SpeedEvil> Ah.
[13:10] <SpeedEvil> Don't you have to be >1200km or so to get out of the nasty stuff?
[13:11] <SpeedEvil> Magnetospherically-wise.
[13:11] <SpeedEvil> Or >350
[13:11] <SpeedEvil> <350
[13:11] <Hibby> well, it looks like geting stuff into space is dead easy
[13:11] <Ikarus> SpeedEvil: yup, for a cubesat those orbits suck balls
[13:11] <Ikarus> you get nuked to hell and back
[13:11] <Laurenceb_> Hibby: could have fooled me
[13:11] <SpeedEvil> Ikarus: You mean ~600km?
[13:11] <Ikarus> but other companies do have sats up there
[13:12] <Ikarus> yeah
[13:12] <Hibby> Laurenceb_: lol
[13:12] <SpeedEvil> I do wonder about laser comms, and magnetorquers.
[13:12] <Ikarus> SpeedEvil: MEO region, which is one of the two radiation belts aswell....
[13:12] <Ikarus> SpeedEvil: you want to be the new Iridium ?
[13:12] <SpeedEvil> Ikarus: I was actually more interested in 'spysats'.
[13:12] <Ikarus> ah
[13:13] <NigeyS> A bomb warning has been received relating to central London, the Metropolitan Police has confirmed.
[13:13] <Ikarus> I am interested in telecommunications spysats
[13:13] <NigeyS> here we go again
[13:13] <SpeedEvil> A lightweight 20cm or so mirror, with a nice CCD.
[13:13] <SpeedEvil> And decent laser comms to push the data back.
[13:13] <Ikarus> but off shopping, back in a sec
