Will we have live NASA TV coverage of the event?

Just checked NASA TV. Nothing related to DAWN at the moment.

I don't expect anything on NASA TV. Not even a phone press briefing. Probably just a text press release after it's all over; they've already done a pre-flyby release.

the team top priority is focused on threading the needle for the slingshot to Vesta.

there are very interesting details here on imaging coordination between DAWN and MEX

A friend of mine on my own forum asks me whether you have any information about the images and when they are expected to be released.

Posted by: mps Feb 18 2009, 11:26 AM

According dmuller's http://www.dmuller.net/realtime/index.php?mission=dawn the main antenna will be pointed to Earth tomorrow. It's safe to assume there will be no images transmitted before that.

There's a bit of a write-up on Space.com, but not much news yet ...

Luckily there's enough GAS onboard the DAWN spacecraft to last for the dual flyby smile.gif

apparently things look good but much more analysis is needed as expected. No official announcements have been posted at this time

Posted by: tedstryk Feb 18 2009, 10:37 PM

Does anyone know when the data is supposed to be transmitted?

Looks like it's like a Mars Odyssey image smile.gif

Here are a few context views from Celestia and Google Earth of this image's location:

Wow, that is a pretty close-up view, if I'm interpreting it correctly. Going by Google Mars, the smallest craters in that view are about the size of Victoria, maybe a little smaller?

Posted by: Phil Stooke Feb 22 2009, 01:12 AM

Right, it's about 55 m/pixel, so a Victoria-sized crater would be resolved. i hadn'r expected such high resolution - looking forward to the rest of the data set!

there will be no more pictures. but the one is gorgeous indeed ! instrument calibration data was collected. The gravity assist went quite well which was the purpose, not to collect science data. Details should be appearing at JPL website quite soon

Edit 27 Feb

Mars Flyby Press release has just issued:

New JPL Mars Flyby Press release has just issued with a cool mosiac comparing the same location of the image taken by Dawn to earlier photos taken by MGS and MEX

See a higher resolution version of the mosaic at my DAWN talk on Apr 15 at Gloucester County College, NJ

So there were more images after all! It looks like they were cloudy or otherwise not very good, which might explain why they were not released. Now maybe we will also learn more about the other calibrations.
