The start time of VOI : 7:07:59 UTC. That zone time corresponds to Greenwich line?

Yes but not BST which is 1 hour ahead at the moment.

I think one of the best places to check for updates will be Emily's Blog

But she will not be able to post in real time.

There isn't wireless Internet access in the big room where the show is taking place, so I won't be able to post as frequently as I sometimes have on critical mission events. Instead, I'll take notes on what happens and when things get quiet I'll run back to the press room to post.

So I guess the most up to date information on the web should be the scrolling news bar on VEX home page.

EDIT :
Main engine burn has begun !

Actually Emily posted the information before the VEX home page.

Good Luck VEX!

Don't know how much can be read into it, but at least the webcam at ESOC shows a green board on the screen:

We seem to have re-acquisition of the s-band signal. No confirmation yet on success but events are following the plan.

Emily: The main engine has shut down exactly on time!

Also from Emily's report :

Also, another useful tidbit this morning, is that Venus Express Project Scientist Håkan Svedhem reported on when the first images are expected: about 48 hours after VOI. They will be released to the public, the program moderator said, on April 13 after 4:00 p.m., I presume she meant Central Euroupean Summer Time, or 14:00 UTC

Weird , nothing at spaceflightnow.com They only seem interested in NASA missions now.

I think they are waiting for the press comference and HGA data in a few minutes from now to see if the spacecraft is healthy.

Is anyone getting the streaming video of the press conference> I;m getting zip.. mad.gif

Im using BBC Online...The briefing doesnt seem to have started yet.

Now says its staring 10am GMT/11 BST

My sound is cutting out.......have they actually said anything about its condition yet? lol


That was like some terrible oscar acceptance speech !!

Emily has been busy. Almost the whole PC is already transcribed on the blog:
http://www.planetary.org/blog/article/00000537/

The PC ran only a few minutes late on the ESA stream, but otherwise the PR of this event was pretty bad. The quickest source of information was still Emily, even though she was runnin back and forth to the mission control and the press room! ESA should employ her for live event reporting :-P

you guys have given this Venus event fantastic coverage

This is great news - congratulations to ESA (and thanks to Emily for detailed news from VOI and the PC).

Now we can look forward to seeing the first images two days from now. It's rather strange that with the exception of 50-100 Galileo images and a few from Cassini these will be the first spacecraft images from this closest neighbor obtained using a modern camera system.
RNeuhaus
Damn smart is VEX! congratulations to the team! Also to Emily for the updated posting.

The PFS spectrometer will determine the temperature and composition profile of

So has the VEX PFS fixed itself then?

I don't think so - IIRC they were going to try the PFS cover again some time after VOI. That text just looks like a copy/paste job into the press release...

...and my congrats to ESA on the successes of VEX & MEX too! Now I think I'll go get some TEX-MEX for lunch wink.gif

There's a bit more from two abstracts from the Fall 2005 AGU meeting on just what they hope to do with VIRTIS where surface observations are concerned:

http://www.agu.org/cgi-bin/SFgate/SFgate?&...P33A-0225"

Also, Noam Izenberg's presentation to last November's VEXAG meeting on the observations MESSENGER will make during its second Venus flyby ( http://www.lpi.usra.edu/vexag/Nov2005/MESSENGER_VEXAG.pdf ) includes, on page 8, a description of a possible attempt to mkake similar observations of surface composition

This was all the more true for Huygens, which images were ridiculously small and tremendously compressed.



The images are not rediculously small...they are framelets....they were never intended to be stand alone images, but rather combined into panoramic 360 degree images. With early 90s technology, as edstrick said, this instrument did a very good job given the data rate/mass/power use constraints. It would have been better to have few images with less compression had both channels been received (with only one received, we would have horrible holes in the mosaics). But this is simply a result of Titan providing a lower contrast environment than expected.
BruceMoomaw
That very nice (and pictorial) document on the DISR photos from last year's Titan Conference which I mentioned down in one of the Titan threads yesterday says that we did manage to get three "almost complete" mosaics, as opposed to the 10 hoped for.

Venus Express has reached final orbit:

RNeuhaus
Wait until June 4, 2006 when Venus Express start to collect observations from Venus. Now it is undergoing the switching on every 7 scientific instruments.

Until beginning of June, Venus Express will continue its ‘orbit commissioning phase’, started on 22 April this year. "The spacecraft instruments are now being switched on one by one for detailed checking, which we will continue until mid May. Then we will operate them all together or in groups" said Don McCoy, Venus Express Project Manager. "This allows simultaneous observations of phenomena to be tested, to be ready when Venus Express’ nominal science phase begins on 4 June 2006," he concluded.


Venus Express will live for only 2 days ! laugh.gif

While Venus Express is expected to spend about 15 months studying its cloud-covered target, the mission will span only two of the world’s exceedingly long days.

I hear the ESA has a scientific probe in orbit around Venus. Anyone else heard that? I wonder what it's doing? Do you think it might send back pictures? Maybe we will get to see them!
lyford
Yes, I hear they plan daily releases of pics, a la MER. (Venusian days.)
RNeuhaus
Maybe, the most-well informed is of Emily with her blog at http://www.planetary.org/explore/topics/venus_express/
However, the news is still cold dated May 9, 2006 as the most recent ones. I am afraid that the time will be cronometred as venusian day as Lyford is smelling! biggrin.gif

There is a more recent update from the 6th of June:

And there are, since April, images available:

http://sci.esa.int/science-e/www/object/in...0913&fareaid=63

OK, it is not a flood of information but there is some...

EDITED: I've contacted the Project Manager Don McCoy but he will be out untill the 12th (maybe he will be at the world cup...who knows?... wink.gif )
Let's see if there is an answer by then...
lyford
Yes, June marks the "Routine Science Operations" becoming, well, routine. (I, despite the highest respect I have for our Quebecois UMSF members, am grateful there are no Poutine Science Operations scheduled.)

I know I can rely on the grace and good humor of this board to get me through the longs dry spells between "daily" releases of information.

Though, as Ustrax pointed out, the VE website does appear to have weekly updates, which is a great thing if they can keep it going. And yes as far as images go like MRO they are few until the operational orbit begins which is now I understand. We should see more soon.

About the updates let's wait untill the 13th to confirm their periodicity... wink.gif

Don't expect to see much more before this:
'The next milestone for the mission is the preparation of the Mission Commissioning Results Review to be held end of June.'
DonPMitchell
Looking at past missions, there is clearly a problem. People in the EU should apply some healthy critcism of this policy of closed data and image access. It is not appropriate to such an expensive publically-funded program.

as an EU citizen my only response to this is - I'm absolutely with you bud. Pressure is being applied little by little but we really need our own TPS here. Well a subset of the TPS that kicked some butt here would also be an option.

Frankly, an "ESA Watch" (no doubt started by a former, disgruntled ESA employee who got laid off) or European versions of our own lovable Cydonuts would probably be more effective. You know, something along the lines of "C'mon, David [Southwood], why is ESA ignoring European taxpayers?" or "They're not showing the VEx data because they're hiding evidence of ancient civilizations on Venus!!!" tongue.gif
BruceMoomaw
Well, yes, but where would the Europeans find someone that dotty? (By the way, a recent E-mail exchange with Keith -- of which I will spare you the sordid details, except that it started out with me trying to compliment him on something -- has confirmed again that his website should feature one of those warning labels that says, "Caution: Contains Nuts".)

This seems that ESA is facing against the powerful democratic way which is the WEB where everybody is the witness of his taxpayer.

Venus Express Commissioning Phase Completed

Paris, France (SPX) Jun 12, 2006

After 207 days of flight, 43 orbits around Venus and many test activities, Venus Express formally completed its commissioning phase June 3 and entered the routine science phase, ESA announced last week.
