Dear all,
We are amazed, and a bit flattered, by the interest that the Dawn mission has awaken throughout the internet and particularly in this forum, and we would like to thank you for it.

Space imagery is frequently subject of discussion and even re-work in these pages, but the field of space operations does not seem to be covered very often. That is why we have decided to offer you all the posibility to ask your questions to the team, that we will gladly reply within the limitations provided by our working agreements with JPL/NASA and the Dawn Science Team.

We would like to request in advance your understanding if we do not reply promptly (or not at all) to some of your questions. We are in a busy and exciting time, and we intend to share this excitement with you as much as we can.

Thank you all for making a great site out of UMSF and for your participation in this topic.

Regards,

Pablo Gutiérrez-Marqués

If I may borrow this space to reply to Fran, even if super-resolution is not a goal of an imaging sequence, there will be opportunities to use it every time a multispectral image sequence is obtained. If a set of images are taken in quick succession through different filters, they can be combined to make a super-resolution composite. I have done this with Voyager images of Hyperion, for example. If there is a lot of colour variation in a scene, as we see on Io, this will not work, but for scenes with only minor colour variation it will be OK, and that will be true for Vesta.

Thanks. I wonder if the backup camera can be operated at the same time as the main, and if the team would get a waiver to do so at Ceres after the end of the primary mission.

Hi Fran,
Yes, both cameras can operate concurrently and indeed, they have done so in the past... on ground. Currently there are no plans ot use both cameras concurrently and we have seen no reason to do so, but if you have a suggestions, please do not hesitate to speak up.

Perhaps to add them if a longer single exposure would suffer from smear.

Another question: is there a priority to capture and download first certain filters? Particulary clear, versus the ones more suitable for RGB, versus the ones suitable for trippy science color.

Yes, the camera implements a download priority scheme in four levels. The top priority is given to images acquired for the purpose of optical navigation (OpNav), like most of the images that we are acquiring now during the approach phase. The other three priorities are assigned to the different image acquisition depending on the purpose of a particular observation.

To all:
I am now on vacation in Spain, so I have limited access to internet. Please be patient in case it takes me a couple of days to answer your questions.

He went on vacation during approach ?........

He went on vacation during approach ?........

Would you rather he took it during the year long Vesta encounter....or would you rather he just went without a vacation for 18 months?
