NASA doesn't give exact dates for the announcement, but rather time frames. The latest I heard is that the announcement will come in July.

Generally, the three finalists all would produce excellent science, and a lot of weight is given to technical and budget risk in the final selection. Since the public can't evaluate those aspects, I've given up trying to handicap which mission is finally selected. TiME, if it has similar risk as the others, may have an edge because it must be selected this round to reach Titan when the northern lakes are in view of Earth to allow communication after splash down.

I voted for TiME... This mission just sounds and looks way too awesome. And this artwork sold it to me too: http://palebluespeck.wordpress.com/2011/06...forbidden-seas/

I also voted for TIME. What sold me was the fear that unless some mission to the outer planets is green lighted soon, I may not live long enough to see one come to fruition. Also a nice taste of what billions of years of low temp chemical reactions have brewed on titan would be very complimentary to cassini huygens.

Same here! If selected, we're right now less than 10 years from landing/splashing (June 2022), which is not too bad.

Actually no. Splashdown is July 2023.
When the TiME Mission was originally conceived in 2007 in response to a NASA study call, a 2015 launch was assumed, with 2022 arrival (which is reflected in some old meeting abstracts, and presentations, I think). In respose to the 'real' 2010 Discovery call, launch is in 2016 with arrival 2023.

Back when I started work on Huygens in 1990, launch in 1997 seemed far off, to say nothing of 2004 arrival. You'd be surprised how quickly the time goes....

Thanks for correction Ralf!
You're rigth, we'll be there faster than we think. On the other hand, Curiosity landing in 3 weeks from now seams faaaar away. This is may be because I check remaining hours 10 times per day rolleyes.gif

Thanks for the clarification!

But I assume the winner will be InSight because of its proven Phoenix platform, solar arrays power source etc. Unfortunate tendency to cut planetary science budget will lead NASA to save money.

Heh, I remember when I first heard about the Cassini-Huygens mission back in 1992. I didn't think my interest in space exploration would last up to 1997. And now I'm a bigger space geek than ever... laugh.gif

Oh I remember the Cassini launch and then thinking "ok in 7 years time it's going to arrive, what do I do in the meantime"
....lol. smile.gif

I assume NASA will have a press confernce to announce the result? Since they haven't announced one yet, I assume the selection notification is still at least several days off?

It seems that way, alas. The Discovery program website http://discovery.larc.nasa.gov/discovery/index.html now says
'July 24, 2012 ... The new target date for the Downselection announcement is August 2012'

My experience with Cassini findings being sometimes deferred during e.g. manned program events is that NASA typically doesn't like to have multiple news stories come out close together which might dilute their individual impact, so I would guess they will not make an announcement in the middle of the MSL/Curiosity landing hoopla.

This is just my guess : I do not speak for NASA.

Bummer, Ralph. I agree with your reasoning, though: ain't nothin' but a delay. Chins up all around.

A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

While I have my favorite, any of the missions would be a great selection. My tingling fear as we wait is that as in 2004, NASA will decide that none of the finalists were acceptable (presumably because of concerns about technical or budget risk that outside observers like myself never get to hear about). At least I can stop checking my new reader three times a day for a bit.
