I assume most of you know about the HiBlog, but I thought I'd mention a few things, and ask if there's anything you'd like to see.

For an update, the process that HiRISE images are processed has been corrected. Come to find out, I didn't know the last steps very well, starting at step 12 things have changed somewhat, they are alot more accurate now.

Anyways, I hope you all enjoy it. I'll expect I'll post something about HiWeb when it enters beta testing, which should be sometime fairly soon (HiWeb is the program that is used for target identification, it will be opened to the general public as soon as it's been made secure.) Other than that, well, we'll just have to wait and see what goes on.

One thing that made me go "eh?" is ", two for each of the 14 CCD"

I can understand one channel - the image data....is the other channel just housekeeping data or there more to it that that?

Actually, the two channels contain about half of the data from the CCD. Don't ask me why it's set up like that, but each contains half of the image. I've made the correction on the HiBlog to reflect that more accurately.

Thank you very kindly for putting HiBlog up. I first found out about it on this site, and have been checking it regularly since. The RSS link is especially useful for updates.

It is valuable and insightful to have this type of informal point of contact with the HiRise team. It is an incredible instrument and deserves as much exposure as possible so everyone with an interest can share in the experience. Please keep it going as I am sure many folks are keen to know what is going on. Here are some things I'd like you to discuss:
What's happening during conjunction at HiROC.
What targets are coming up?
When will the first stereo images be acquired and released, and at what resolution?
How will the public targeting process work?
How accurate have you found the instrument pointing subsystem to be? Seems bang on so far.
Are there any unusual pointings planned (eg. far off nadir, or downtrack)?
How has the CRISM team (and others) been using the HiRISE results?
How have you benefitted from the context and color imagers?
What type of image processing are you doing?

Thanks again for providing a terrific and interesting resource!

Let me just tell you a few. First of all, there is a post about what's happening during Conjunction, it's the one right below the post about how HiRISE images are released.

No information about future targets can be posted, sorry folks. All I can really say is that among the first targets will likely be most of the landers who were sucessful, which helps with calibration, and Phoenix canadate landing sites. I'm sure we'll get alot of other interesting things as well, stay tuned. We would really hate to get the public excited about something, and find that some kind of error caused it all to go away, forcing us to take another picture. Imagine if we had announced that we were taking a picture of Oportunity, only to find that there was a gap right where Oportunity was... It'd have been a bit ugly. So, the bottom line is, future picture locations can't be announced to the general public.

More information will be posted about HiWeb when it gets closer to it's release. HiWeb is the system by which the public will be able to request picture locations.

What do you mean, what type of image processing are we doing?

We've seemed to be within maybe 50 meters on the ground of our target, perhaps even closer, I haven't done the figures. But they do appear to be pretty much right on, I'm sure it's nothing more than that.

From my point of view, anything posted on HiBlog is like manna from heaven. Even for MER which has set a high bar for excellence in public outreach and access, details of the planning and activities going on on the inside are scarce, until we get a nugget in Steve's blog, or read the official sol reports once released months afterward.

I would like a bit more detail about present activities. Like what is the team talking about re: instrument performance, data volume, communication, commanding.

In terms of image processing, I was hoping again for more detail. For example, the colours in the Victoria image are incredible, but how were they derived from spacecraft data? It's obviously a bit of an art form to interpolate for the missing wavelengths, so some thoughts on that process would be interesting. There's plenty of time for this to develop in the blog though.

I can understand why you would not want to discuss future sites to be imaged. The element of surprise worked well to develop interest in the spectacular Victoria image. Any general remarks though are appreciated. I personally think it would be great if scientists and engineers on publicly funded missions were as open as possible with the public without worrying about small mess ups. Your blog takes us closer to that ideal.

In any event, the blog is a great complement to the mission and I hope you are able to continue it as long as the instrument is sending back data. Thanks again.

I think we'll get enough information once the mission is really 'on its way' MarkL. The people behind the scenes probably have enough work as it is right now, guiding everything succesfully, and I can imagine there's little time left to devote to public info right now.

We've had a lot of data ALREADY from MRO, hats off to that.

Maybe you're right Nico, but I haven't heard that from Tuvas. I have though heard exactly the same thing repeated many times over many different missions. The HiRISE blog goes against that trend though. They have shown a real interest in putting more information out and making the mission very accessible to the public. So we should talk about what we'd like to see and know about. I'm sure they will still have the time to run the investigation smoothly.

Something I should probably tell you about the HiBlog is that virtually everyone who has posted (Except for the HICommander) is under the age of 30. We are all really quite busy, more stuff wil come, trust me on that one. The difference is those of us who are younger have grown to expect to get more from online sources, and thus we provide them. Still, we will try to post at least somewhat often to let you folks know what is going on, but now is a really busy time around here...

Whatever you guys can manage to get on the HiBlog is well received. There's never enough time in the day to do stuff like this, but hopefully it helps to know that it really is appreciated.

Under 30? Actually, more than half of us posting on HiBlog are over 30. But thanks! smile.gif

You don't even know how much that helps. :0) The link to this topic has been making the rounds here at HiROC this afternoon and we are all thrilled and delighted. At a meeting this morning our operations manager mentioned that he hopes we continue updating HiBlog because he can tell from forum he has come across (maybe this one?) that people are responding positively.

I guessed wrong then... Still, most of the posters are under 35, and almost all under 40... Right?

I think that we're beginning to see a new generation and new genre of outreach for spaceflight that goes beyond the normal. Blogs, Podcasts, automated imagery pipelines. Some missions ( and fortunately an increasing number ) are embrasing this technology fully, sharing not just the headline results of a mission or an instrument - but going to the trouble of sharing the experience and the adventure of being a part of such a project.

As I mentioned in my glog week, HiRISE is billed as the peoples camera, and so far, on all fronts, the people approve. For going above and beyond the call of duty and taking enthusiasts, HiRISE gets my thanks, and the UMSF seal of approval....if there was such a thing smile.gif

(PS - I think we had a "how old" or "who are you" or "what do you do" thread at some point....in the dark corner of the community chit chat forum somewhere - the 'sweet spot' is 25-40 basically. )
