New feature on the HiRISE website! HiFlyers made of released images like this one:

These are 11×17 PDFs showing cutouts of new releases, so you can print your own posters. Currently these are available for weekly releases starting 3/25/09 – look for more with each week’s new images!

They’re all available on this page. There are also links to the flyers on the individual image pages such as this one: http://hirise.lpl.arizona.edu/ESP_011425_1775 (Look for the “HiFLYER” link in the lower right hand side.)

Enjoy!

Our image web pages all have this great map feature (click the image to the right for an example). (It’s been there for a while, so you may have noticed it already.) If you scroll down to the bottom, below the Observation Toolbox, you’ll see a mini context map from Google maps for the specific image whose page you’re viewing. It’s so useful to be able to see the HiRISE footprints placed on a broader view of Mars, showing the surrounding geology. Plus, you can pan and zoom around in the map. Way cool.

Our awesome technical group sent me the link to a page that calculates an overwhelming number of different statistics for our website. Visitors are broken down by country (lots of Canadian fans!), where they go, how long they stay, what browsers they use…. For the most part, I think people come to the HiRISE website to look at our images – which is as it should be! However, I was astonished to see how many hits the HiBlog gets. We don’t get all that many comments (except for the record-breaking MPL search entry), so here I was, thinking we were in a little bubble of self-absorbed anonymity, talking to ourselves….

My protective bubble burst when I saw the number of hits we got over the past few months:

• April: 36,200!
• May: 99,200!
• June: 44,500!
• July: 36,410! (as of this morning)

(The huge number of hits in May was probably due to the combination of the MPL search and the Phoenix imaging.)

…although this could just be 10 people who really love us, hitting “refresh” 4,000 times a month.

I don’t know how this compares to other websites, but I’m humbled and a little intimidated to find we have so many readers! I guess we should write more entries (and better ones!) We’re hoping to recruit some more team members to post, too. Ideas or requests for blog entry topics are welcome! Leave us a comment below.

A while ago we posted a list of Frequently Asked Questions: http://hirise.lpl.arizona.edu/faq/ (There are also links to this over on the right of the HiBlog, and on the menu at the top of all of our HiRISE pages.)

A lot of these FAQ have to do with the different data products we release, and how we plan and process the images. There are also definitions of some of the terms we use, which we know can be confusing! Hopefully you’ll find these helpful. If you have questions about HiRISE images, how we work, or anything else, check out our FAQ. If your question isn’t answered in there, please ask us your questions below in the comments. We’ll try our best to answer them, and the FAQ will grow!

One FAQ I’d like to address is, “Why don’t you take an image of X?” where “X” is the asker’s favorite spot on Mars or other celestial body. My answer:

I want to point out this awesome new feature on our website. This week’s captioned releases were accompanied by a really cool movie. It scrolls over some areas of the images in high resolution. It’s a nice way to cruise around the observations, and I love how it shows off the color. This might be an easier way to quickly browse the images for people who don’t use the IAS Viewer.

The movie might be a little hard to find; if you click on the “Updated: 19 March 2008″ link in the upper right of our main page, it will take you to this page, which shows this week’s releases. There, in the lower right corner, there are links to the scroll clip. It’s available in Quicktime, an “AppleTV” format (which plays for me in iTunes), and a smaller one for your iPhone. There’s even a groovy soundtrack! Thanks to our masterful webmaster who put this together. Let us know how you like it!

Three HiRISE papers are coming out in a special issue of the journal Science today. Our science team has been working hard on analyzing the images we take, and they’ve discovered some interesting things.

One paper talks about a few aspects of the history of water on Mars: HiRISE images of “rock glaciers” and bright deposits in gullies that might be extremely recent. HiRISE observations of an area called Athabasca Valles were used to show that it is actually covered with a thin veneer of lava. A third paper discusses thin layers in the North Polar cap. HiRISE is able to discern very fine layering (seen in an excerpt of image PSP_001636_2760 at left), as well as the color and thickness of each layer. Since these layers were laid down over hundreds of thousands of years of Martian history, they provide a record of climate change on the planet.

You can find a lot of things on the HiRISE website that are impossible to include in a print journal – like full-resolution color versions of the images from the papers, and (my favorite) cool 3-D flyover movies of the stereo observations. Our webmaster designed this lovely page for accessing these special products. Have fun flying over Mars!

Tomorrow is the first launch opportunity for our sister mission, Phoenix. We don’t have a lot of day-to-day interaction with the Phoenix project, because their building is located a ways off-campus. It’s hard not to feel some camaraderie with them, though. Not only did HiRISE image a lot of possible landing sites, the mission is based right here in our department at the U of A.

If you aren’t super-excited about Phoenix yet, just try and not get excited by this awesome trailer they put together! (Alternate formats are available here, and on youtube, of course.) I was completely enthralled. It’s got everything — action, suspense, an emotional back-story, a totally Hollywood time-lapse mega-zoom to a night launch scene, and a rockin’ soundtrack!

The whole Phoenix website is fabulous, too, if you haven’t seen it yet.

Launches are risky times, and we’re all nervous and excited for Phoenix. All our best wishes go with it as it leaves this planet!

Have you SEEN the new website yet???

If not, why are you reading this? Go look at it! It’s beautiful!

Besides the cool new look that shows off our beautiful images so nicely, the new website redesign also has some fun AND super-useful new features: a searchable catalog of released images, illustrated explanations of all of our science themes, HiRISE “To Go” for mobile devices, & more.

Spacecraft missions are complicated endeavors that result in a wealth of scientific and engineering data. Long after the mission has ended, these data can be extremely useful for later study and discovery. With so many missions over so many years, how can later generations find and make use of these data?

The solution for many NASA missions has been the development of the centralized Planetary Data System (PDS). The PDS is several things: a collection of websites, a search capability, an archive, a database, a learning tool, etc. The PDS Imaging Node is located at http://pds-imaging.jpl.nasa.gov/ and acts as “the curator of NASA’s primary digital image collections from past, present and future planetary missions.” These missions include Voyager, Galileo, Cassini, and many more. Now the Mars Reconnaissance Orbiter (MRO) has been added to the list, with the HiRISE team releasing our first several months of image data.

• MRO PDS page: http://pds-imaging.jpl.nasa.gov/Missions/MRO_mission.html
• MRO Product Search page: http://pds-imaging.jpl.nasa.gov/search/index.jsp
• HiRISE Volume: http://hirise-pds.lpl.arizona.edu/PDS/

What we have released is an archive of the HiRISE Experiment Data Records (EDRs) and Reduced Data Records (RDRs). EDRs are in the *.IMG file format and represent individual CCD channels (remember, there are 14 CCDs in the HiRISE camera and two channels per CCD, for a total of 28 channels). These EDRs are cleaned up, calibrated, stitched together, and mapped to Mars’ geometry, resulting in the RDR products. RDRs are in the *.JP2 and *.LBL formats. JPEG2000 is the technology that enables us to offer our gigantic images to the scientific community and the public in a timely and efficient manner. An observation’s image data are in the *.JP2 file and its meta data are in the detached *.LBL files. To view these products, JPEG2000 compatible software is required (see our site for a list of offerings).

While we have been trying to release up to five captioned images a week for the past few months, the PDS release represents several hundred images, most of them without captions. You can find them using the PDS search capabilities, and you can also find them on the new HiRISE site, unveiled today to coincide with this first PDS release. The redesigned site focuses on the images while providing, hopefully, a more user-friendly interface:

• HiRISE Site: http://hirise.lpl.arizona.edu/
• “About Our Redesign”: http://hirise.lpl.arizona.edu/profil.php
• Images released to the PDS: http://hirise.lpl.arizona.edu/pds_release.php

As word gets out about the new site and the PDS release, you may experience some site slowness. Please be patient, and thank you for your interest!

Some of you out there may be asking: what happens to a HiRISE image between the time that it is taken and the time that it is released to the public? Well, I’d like to give a summary here.
