goldenpeach Posted November 10, 2014 Share Posted November 10, 2014 Hi!In case you don't know, a lander is about to land on a comet, his name is Philae.It will separate from the it's mothership this wednesday, the signal of the landing is expected is arrive on earth at 11h02(EST).If you want to see it live, there is three link for that(I'm not sure which one will provide the stream but it will start wednesday at 9H00 EST):-http://rosetta.esa.int the webcast start tomorrow at 2h00pm(EST)-http://new.livestream.com/ESA/cometlanding It is linked from the previous link as "Watch on live-stream?" so I think this is the good link-http://www.livestream.com/EuroSpaceAgency the place for the ESA live-stream.Have a nice day!(I know there is already a thread for about that mission but I made a new threa to give the link because I wanted it to be more visible: if I posts the link on the mission's thread, it will probably get lost, let alone the fact that not everyone who want to see the landing in a live-stream will read that thread.

astropapi1 Posted November 10, 2014 Share Posted November 10, 2014 They're doing live streaming of the first landing on a comet. We've come a long way, haven't we? Link to comment Share on other sites More sharing options...
goldenpeach Posted November 10, 2014 Author Share Posted November 10, 2014 yeah...I will be watching this with a LOT of excitement: I missed Curiosity's landing and I don't want to miss this! Link to comment Share on other sites More sharing options...
Umlüx Posted November 11, 2014 Share Posted November 11, 2014 thank you. i would have missed this otherwise. and that would have been a shame given we europeans achieve something like this at last. Link to comment Share on other sites More sharing options...

dharak1 Posted November 11, 2014 Share Posted November 11, 2014 This is the first landing on a comet? Didn't Japan land a probe a while ago called Hyabusa or something recently and they were putting names on the second one? Or was that just and orbiter?

Didn't Japan land a probe a while ago called Hyabusa or something recently and they were putting names on the second one? Or was that just and orbiter?That was an asteroid (25143 Itokawa) - Hayabusa observed, landed and returned samples to Earth during a roughly 7 year mission.

dharak1 Posted November 11, 2014 Share Posted November 11, 2014 Ah, I always get them mixed up. Isn't the difference about outgassing and the periapsis and apoapsis or something like that? Or how comets have tails? Link to comment Share on other sites More sharing options...
Boomerang Posted November 11, 2014 Share Posted November 11, 2014 (edited) Ah, I always get them mixed up. Isn't the difference about outgassing and the periapsis and apoapsis or something like that? Or how comets have tails?Comets are icy bodies. Because of that, you get the outgassing and tails when they're nearer the Sun. They tend to have more eccentric orbits, but you could have a rocky body with an eccentric orbit and it would still be an asteroid.Edit: And thanks for the reminder about the landing!

Scotius Posted November 11, 2014 Share Posted November 11, 2014 Of course, some asteroids on eccentric orbits could be old, dead comets that lost their load of volatiles long ago. And Ceres is emitting water vapour, so it could be called a comet, because of ongoing outgassing Line is a bit blurry on this. Link to comment Share on other sites More sharing options...
Kryten Posted November 11, 2014 Share Posted November 11, 2014 This is the first landing on a comet? Didn't Japan land a probe a while ago called Hyabusa or something recently and they were putting names on the second one? Or was that just and orbiter? Hayabusa did have a dedicated landing probe called Minerva; it was much smaller than Philae, but could move about using a 'hopping' mechanism. At least, that was the plan-due to a computing glitch, it was released while Hayabusa was adjusting it's orbit, and missed Itokawa completely.

goldenpeach Posted November 11, 2014 Author Share Posted November 11, 2014 Yes, and the best part of the stream will start tomorrow at 9h00 EST!I can't wait for that Link to comment Share on other sites More sharing options...
Motokid600 Posted November 11, 2014 Share Posted November 11, 2014 What can we expect with the webcast? Just telemetry? Or are we going to get real time images from the lander? What's the delay?And.. 9h00 EST. Is that AM or PM eastern time? Link to comment Share on other sites More sharing options...
Kryten Posted November 11, 2014 Share Posted November 11, 2014 And.. 9h00 EST. Is that AM or PM eastern time? I'm pretty sure he meant the release of Philae, in which case it's actually 09am UCT, which is 4am EST. Link to comment Share on other sites More sharing options...
tygoo7 Posted November 12, 2014 Share Posted November 12, 2014 So the touchdown will be at 9:35am CST and landing confirmation will be at 10:02am CST? Link to comment Share on other sites More sharing options...

Wjolcz Posted November 12, 2014 Share Posted November 12, 2014 The lander is getting separated from Rosetta in an hour and will be landing at 17:00 Central Europe Time. At least that's what I heard from the TV. Link to comment Share on other sites More sharing options...

heng Posted November 12, 2014 Share Posted November 12, 2014 (edited) you are all watching the "live" stream as a comic? XKCD is doing a live drawing stream...I am watching this via http://xkcd1446.org/ for easier access.PS: at the office, can't watch the "real" mission room live stream :-( Edited November 12, 2014 by heng reason Link to comment Share on other sites More sharing options...
Sky_walker Posted November 12, 2014 Share Posted November 12, 2014 Seems like there's plenty of people who can't view it live, so... here is how it looks like most of the time: Link to comment Share on other sites More sharing options...
Geschosskopf Posted November 12, 2014 Share Posted November 12, 2014 http://new.livestream.com/esa/cometlandingAbout T-30 to landing. The boffins seem to think it's working OK so far. IOW, it's now about the time for the Kraken to attack, or the game to crash, or for the boffins to realize they forgot to install a key part, or learn they screwed up the action groups, etc .EDIT: I wonder if they'll rage-quit of something like that happens .

Camacha Posted November 12, 2014 Share Posted November 12, 2014 It seems switching browser and installing a different version of the Flash Plugin helped here - the stream has been stable with the new configuration so far.http://new.livestream.com/esa/cometlandingThat doesn't work in a media player, that is why I was asking for the direct address Link to comment Share on other sites More sharing options...
rkman Posted November 12, 2014 Share Posted November 12, 2014 Philae will approach at relative speed around 1 m/s .... the comet's escape velocity is only around 0.5 m/s. (wiki) Link to comment Share on other sites More sharing options...
