Such exciting news. I'm beside myself with glee! :jump:
Lil washing machine sized Philae has been heavily on my mind the last couple of days- maybe he felt my vibes :P.

I've been watching this mission closely.
it'll be quite interesting to see what they do with Philae's location as it's wedged in a crevice. Bounce him out (unless the jets do it naturally) or leave him there as too risky with the jets. But either way- it's going to be toast soon come perihelion in August anyway right :shrug: ? So maybe they'll take the risk in the name of science :question:. Not forgetting that those unplanned bounces brought us heaps of great data.

Can't wait for the drilling to start- it's going to be their top priority.

P.S. I want a press conference. And I want one now! :einstein:

Wow, thanks Ron. Wasn't expecting we'd ever hear anything from it again. Exciting news. Hope they get some more good data from it! :thumbsup:

Seems they think it might be quite fortuitous being where it is as it will have a chance of surviving a lot longer into the swing past the sun. It would have cooked out in the open in the original spot.
A Grandstand view of it all from the covered stands ...:thumbsup: Be absolutely amazing it it comes out the other side still going, incredible science opportunity.

Fingers crossed for little Philae :)

This is excellent news.:thumbsup::thumbsup::thumbsup: :thumbsup::thumbsup:

I was really disapointed when the original landing
went belly up.:(

Looking forward to whatever info the tough little bit
of high tech sends back.

The first thing I heard this morning, as I shot through the kitchen on my 'bed to toilet' dash, was my wife saying: "<garbled> has woken up!". Huh? I thought. We don't have guests staying.

Anyway, the lander news is very good and I'm sure there are a lot of happy 'eggheads' at mission control. Hopefully they get to do some of the science that was planned.

Things aren't going so well at the moment :(.

From Dan Fischer, via facebook's Comet Watch group:

Sorry to disturb the party but ... after the brief communication Saturday night (European time) Philae has not talked to Rosetta again and has now missed the two subsequent communication windows Sunday at noon and Sunday evening. This can have geometrical reasons, and the orbit and strategy of Rosetta will be adjusted soon to improve 'viewing' conditions, but we aren't out of the woods yet. *If* stable comms can be established, http://news.sciencemag.org/.../scientists-celebrate-comet... (http://news.sciencemag.org/europe/2015/06/scientists-celebrate-comet-lander-philae-s-call-after-7-month-slumber) describes in detail what would happen next, payload-wise.

:help: :prey: :prey2:

Below is a great article by Bob King (cool animation pics of Philae as well) and a statement from Klim Churyumov.
There's also a nice nod to the PACA community which some of our members here including myself are part of :) .

Thanks for the update Suzy.
While this certainly isn't good news I don't think it's really all that surprising.
I'm sure she'll pull through and I can't wait to find out more about the final landing site :)

its amazing the batteries are still working after 7 months. Must be energisers LOL. Its really great news that PHilae is still working. I think Philae must of been getting a small amount of power over the past 7 months but just not enough power to transmit.

pluto

15-06-2015, 02:16 PM

I'm not sure if anyone's mentioned the battery condition yet. As far as I know the batteries are not charged and Philae has only been awake while its solar panels are generating electricity.
The article that Suzy linked to mentions:
"Finally, if the power supply improves slightly, or if it can be used to charge Philae’s drained batteries..."

Thanks Hugh, it's a pleasure :).

This has just finished airing on The Sky at Night (on BBC 4) :
Rosetta Update - A Comet's Story.

The site won't let me access it as I'm outside the U.K. and I can't find it anywhere else online, including YouTube. So if anyone has any luck could you p-l-e-a-s-e post the link here? Thanks :).

Also, for those that missed this link in one of my previous posts, please read it. It is by far the most comprehensive article to-date.

Eric Hand writes absolutely brilliant articles on the Rosetta Mission.

Some good news :D.

From Jonathan Amos on twitter:

The good news today is that @Philae2014 (https://twitter.com/Philae2014) again made contact last night. Three short contacts of about 10 seconds each.

https://twitter.com/BBCAmos/status/610371256727244800

And here's the telemetry (though it's over my head!)

Thanks Ron. I think I've kind of taken over your thread in your absence :lol:.

I have two latest updates worth reading, courtesy of Dan Fischer.

Right now they have to do some re-pointing with Rosetta to talk with Philae- the trajectories of the Rosetta orbiter will need to be adapted to allow longer contact times with Philae.

Philae is receiving at least 3 hours of sunlight a day, which supplies it with energy. It was expected to only receive 1.3 hours of illumination.

Before the team can command the Philae, stable and long duration connections to the lander must be established. Only then, can the prepared procedures for the scientific work with its 10 instruments be uploaded and the next experiments begin.

The order in which the instruments will be activated will be determined once Philae's health has been fully analysed.

Once those boxes are ticked, science is expected to start at the end of June or early July.

It's great poor little Philae hasn't been abandoned and isn't dead and will allow for some creative solutions that might be considered too risky on other programs. It's all useful data.

Thanks for the Telemetry link Suzy, fascinating. They are just showing battery condition, amps delivered and temperature of the various modules although it looks like it is not being updated very often and temp is not being logged as far as I can see yet. Could get interesting once they get better comms going and it warms up some more. Another article I saw said they were quite optimistic about it returning to operation for a lot of the science missions.
Fingers crossed ..:thumbsup:

That telemetry page is pretty interesting, thanks for the link Suzy :)

That's amazing if the ESS and MSS are really well above zero, I wasn't expecting that already!
Surely that CIVA temp is not an actual current measurement...?

Suzy requested the sky at night episode... I've uploaded it here for everyone ...

havnt watched it yet but it should be interesting
enjoy
matt

edit : I hear people are having issues with windows media player only playing back the audio and not the video. I tested on my sisters win8.1 machine and had the same issue. you could try installing other software that plays mp4 with the h.265 codec or putting it on a smartphone and use vso player.

the video plays fine on my xp machine with divx pro, on the TV though wd TV live media Centre and also on my phone using the stock video player. sorry if there's any inconvenience.

ZeroID

16-06-2015, 01:49 PM

From what I could deduce Hugh that info was just from a short burst on the 14th when it first woke up. No further updates since. The previous data was from back in November 2014 ! Hasn't moved since I've been watching it.
Hopefully more to come ... my fingers are still crossed :thumbsup:

pluto

16-06-2015, 02:10 PM

From what I understood the latest of the short 10 second contacts did contain data about the current state. Not sure where I read that, I'll see if I can find the link.
I guess that still doesn't mean that the telemetry page is using the new data though.

EDIT:
From here:
http://www.esa.int/Our_Activities/Operations/Philae_wake-up_triggers_intense_planning

"A second, smaller burst of lander data was received on Sunday, 14 June, at about 21:26 GMT, lasting just a few seconds. These data were confirmed to give the current status, showing the lander’s internal temperature had already risen to –5ºC."

And also from here:
http://www.dlr.de/dlr/en/desktopdefault.aspx/tabid-10081/151_read-13918/#/gallery/16734

"The data acquired during the second contact confirms that Philae, which is on the surface of Comet 67P/Churyumov-Gerasimenko, is in good condition and ready for operations"

If you mouse over the charts in the Telemetry it gives you a lot of information in a 'bubble'. Going to have to keep an eye on that little gem.
Better on my home PC than at work. For some reason it's partially blocked on the interactive components for temperature.

Aha, but just checked. Works ok on my tablet on the works guest Wifi ... cool .. or in this case -5C LOL

pluto

17-06-2015, 09:31 AM

Regarding the telemetry page this was posted on UMSF about 7 hours ago:

"The webmaster at http://isee3.p3s.nl/philae/ confirms that these are old data. Notice the other readings, which relate to pre-delivery status. S/he says: "....I've been meaning to update.....""

EDIT:
Further down the thread was this too:

"while it is correct that the webmaster of that site mentioned that he should probably update it he did also mention that it is showing the latest data on twitter. The only parameters that are currently updated correctly for Philae are PSSH_C_SBat_CH as well as PSSH_C_SBat_DCH which are solar panel current and rechargable battery current. Most data is from the 13th but there are also a few measurments from the 14th."

Suzy

17-06-2015, 10:59 AM

Thanks for that Hugh :).

Hi Brent, I agree- hovering the mouse over the temp chart is pretty cool isn't it :lol: . I was going to respond last night but I fell asleep, to let you know it was live.
I'm having a lot of fun playing with it, I feel like a project scientist :einstein:

I too would like to know what that 359.00 °C is all about :confuse3:.

no probs, sorry.

and yes I meant to say VLC not vso.

let's hope the press release sheds some light on how she's going and their predictions as the comet approaches the sun. exciting times ahead.

Just watching an ESA briefing where they say no further contact has been made after the initial "wake up".
8 instruments have "done science"
And they expect that August will be the best month for more contact with Philae as that will be when it is best placed for receiving more energy.
http://www.esa.int/spaceinvideos/esalive

Lots more news though, mostly positive.

It kept freezing so badly, after one hour decided to give up. I couldn't get it to run for more a couple of minutes :mad2:.
I'll have to wait till it's finished and catch the recording from the Live Archive. It's on the right side of the page if anyone else has missed it.

How did you go with live streaming - did it come through okay? I hope you had better luck than I did.

183876

Great news! Rosetta and Philae are in contact again.

This is the first contact from Philae since 14th June.

The two contacts received by Rosetta lasted two minutes each. Both delivered numerous packets of lander housekeeping and status data, 185 in total, which are still being analysed at the time of this writing. No science data were anticipated or received.

New commands have been uploaded to Rosetta to further adjust its trajectory and distance from the comet to improve the radio visibility between the two spacecraft, with the first sets of thruster burns having taken place this past Wednesday and the next set planned for Saturday morning. The goal is to bring Rosetta to about 177 km from the comet nucleus and keep it in a range of latitudes that maximise opportunities for lander communication.
