A quick update on Planet Four: Terrains. I’m working on the first paper draft and planning on submitting it to a science journal by early February with any luck. Currently the draft is being iterated on; I’m incorporating comments and feedback from the rest of the science team. The paper focuses on the distribution of spider features on the South Pole based on Planet Four: Terrains assessments. So stay tuned for more on that over the coming months.
In the meantime, I’ve also processed the subject images currently retired from the newest set of images on the site. We’ve found interesting areas with spiders and baby spiders that we’d like to get a closer look at. We’re hoping that HiRISE will image these over the coming months. The days on the South Pole are getting shorter. May 5th 2017 marks the official start of Southern Fall Equinox. In a few months time, we’ll have to wait approximately 2 Earth years for an opportunity to image interesting regions of the South Pole with HiRISE found by Planet Four: Terrains.
Processing the retired subjects from the current set of CTX images on the site, we found four new regions of interest thanks to your collaboration that we want to take a better look at. We have requested HiRISE imaging. So the race is on to get through as many of the P4: Terrains subject images as we can before there won’t be enough sunlight for HiRISE observations. If you can spare some time, place help classify an image or two for spiders, baby spiders, channel networks, swiss cheese terrain, and craters on http://terrains.planetfour.org
Thanks to all your help, we’ve completed the review of the Season 4 observations of Giza, Ithaca, and Macclesfield. We have new observations from Season 1 from a two different areas around the South Pole now uploaded and live on the site. These areas are nicknamed Starfish and Caterpillar for the spider morphology that have been seen in those areas. Caterpillar is much further away from the South Pole than some of the areas you’ve reviewed here before.
It will great to see how the numbers and sizes of fans and blotches in these two areas compare to Manhattan, Macclesfield, Inca City, Ithaca, and Giza. Dive into these new images today at http://www.planetfour.org
I once did a very similar search with Mars Orbital Camera (MOC) images. The camera worked on Mars Global Surveyor from 1997 to 2006. It had 2 sub-systems: a wide-angle camera and a narrow angle camera. The narrow angle camera obtained grayscale images with resolution from 1.5 to 12 m per pixel. It was just good enough to resolve larger spiders and fans.
In 2004 I looked through all MOC images that existed at the time and were located south of latitude -75º. I was hunting for spiders. The result is a list of MOC images that feature spiders and it is now being added to Integrated Database of Planetary Features. It will be available as a layer in JMARS system in a couple of months.
You can see Spiders map on Database of Planetary Features.
When we have a catalog of CTX images with spiders created by you, we will also integrate it into this database! Then everyone can easily navigate around different locations of spider terrains.
Over the past many months you’ve been reviewing Season 1 observations of areas nicknamed Macclesfield, Giza, and Ithaca. We’ve now finished the current set of data live on the site. We’ve recently prepared and uploaded Season 4 observations of Giza, Ithaca, and Macclesfield so that we can see how the carbon dioxide jet and fan formation processes evolve over several Mars years in these areas.
Thanks for all of your help, we couldn’t do this without you. The clustering algorithm to combine all of your markings together is nearly finished. We’re making hopefully the last tweaks and improvements. This means that over the next six months to a year we’ll be able to compare the results from your classifications of these new images to Manhattan and Inca City, where we already have four Mars years of HiRISE images classified on Planet Four.

The latest set of Planet Four: Terrains images comes with some added bonus features on Talk. Thanks to upgrades in the Zooniverse platform we can now display additional information with the metadata icon on Talk that won’t appear in the classification interface. So we can share the original parent CTX image name and a link to the image on Talk for your further investigations. We don’t show this information in the classification interface in order to keep the classifications free from any potential causes of bias.
So now when you classify, if you want to check out the full frame CTX image the subject is derived from, just click on the ‘Talk’ button after submitting your classification. This will bring you to the Talk Subject Page for this subject. Then if you click on the ‘i’ icon below the image,the metadata window will pop up (see below)
!filename is the internal filename the Planet Four: Terrains used to name the subject when we generated it. !CTX_filename is the name of the full frame CTX image the subject comes from. !Public_CTX_link will take you to the MRO Context Camera Image Explorer where you can view the image (the link was working earlier to directly show the CTX image but isn’t working for me at the moment. If you have any issues you can always copy and paste the CTX filename into the search box and that will bring up the image)
Brand new images are now available on Planet Four: Terrains. Thanks to your help we finished all the live data on the site earlier this week. We have now uploaded new data, and we’re now expanding out to further distances away from the south pole to explore the frequency of spiders, baby spider, channel networks, swiss cheese terrain, and boulders.
These observations span latitudes of -70 to -90 N degrees as shown in the figure below. The red shows the outlines of the new CTX images loaded and ready on Planet Four: Terrains, the white is the original set on the site at launch, and the green areas are the locations/images reviewed on the site over the past several months. The new dataset is the only one so far on Planet Four: Terrains that explores the -70 to -75 N degree latitude ring about the Martian south pole.
The science team is working on the first paper from the project based on the white set of images classified (see above) on the site, and new regions of interest are scheduled to be imaged in higher resolution detail with the HiRISE camera. With more of the south pole surveyed with the classifications Planet Four: Terrains, who knows what we’ll find! Classify an image or two at http://terrains.planetfour.org
Inspired by the images of Swiss Cheese Terrain like these examples below shown on Planet Four: Terrains, volunteer Albert Laubi (xflyer) made some visually stunning paintings using acrylic, oil, sand on canvas)and shared them on Talk.
Here’s some words from Albert:
(Great) Natures forms seen through (excited) human eyes.
Stunned by the variety of shapings that emerge on Mars’ south pole and impressed by the brilliant achievements of scientists, which enables us to make visible things like that even on a far away planet, I got the idea to combine this into a series of pieces containing kinda triple artwork: nature, science and (my) personal perception.
Technically I arranged in Photoshop some parts of similar b/w Mars terrain pictures to a composition, extracted chosen areas for colorizing and texturizing, then put this different layers through all paces, till I had a balance, where I could say: Yeah, let’s paint it! The original size of each painting is 50cm x 50cm.
Check out Albert’s pieces below:
Thank you Albert for sharing your work. If you have any Planet Four or Planet Four: Terrains inspired artwork or poetry, we’d love to share it. Post a link to your work in Planet Four Talk or Planet Four: Terrains Talk
Inspired by Lord Alfred Tennyson’s Locksley Hall, on Planet Four Talk Pete (p.titchin) reflected on the arrival of Martian Southern Spring. We thought it was lovely and wanted to share with all of you. Thanks Pete:
In the Spring, the sunrise heralds changes on the Martian ice: In the Spring, a P4 classifier’s fancy lightly turns to thoughts of —-SUBLIMATION!.

Today marks the first anniversary of the launch of the Zooniverse Project Builder Platform and with that today also marks the 1st birthday of Planet Four: Terrains. You can read the blog post by Zooniverse PI Chris Lintott from that day. We were thrilled to have the opportunity to create this project due to the capabilities offered with the new Zooniverse project builder. Planet Four: Terrains is truly a project we wouldn’t have created without it; many thanks needs to go to the Zooniverse development team who created and continue to support and enhance the project builder.
When we launched Planet Four: Terrains, we really didn’t know what we were going to find. The science team thought the project would discover a few interesting areas with spiders to follow-up. An Earth year later, 10,000+ people have effectively moved a NASA spacecraft and decided where it will image! Now we have 20+ regions that were forwarded to the HiRISE team and ultimately selected to be imaged by the HiRISE camera. HiRISE aboard Mars Reconnaissance Orbiter will examine the areas in more detail and for many see how they evolve with multiple observations spread over the coming Spring and Summer on the Martian South Pole. This is incredible! HiRISE has ~20x higher resolution than CTX subimages shown on the site, so we should get exquisite detail of the spider channels and any seasonal fans and blotches that form. Next week marks the official start of Spring and the return of the Sun to the South Pole of Mars. As the lighting improves with the ever increasing sunlight, the first HiRISE images from these new targets should start coming in soon, we hope. Stay tuned to this space for updates!
Thank for your time and effort on Planet Four: Terrains. We couldn’t do this without you. As our way of saying thank you, we’ve created a collection of all the subject images selected for high spatial resolution HiRISE imaging. You can peruse it here. With any luck in a few weeks, we’ll be able to share some of the first HiRISE images of these areas from this Mars Year’s seasonal monitoring campaign.

Today we have a post by Dr. Candice (Candy) Hansen, principal investigator (PI) of Planet Four and Planet Four: Terrains. Dr. Hansen also serves as the Deputy Principal Investigator for HiRISE (the camera providing the images of spiders, fans, and blotches seen on the site). She is also a Co-Investigator on the Ultraviolet Imaging Spectrograph on the Cassini spacecraft in orbit around Saturn. Additionally she is a member of the science team for the Juno mission to Jupiter. Dr. Hansen is responsible for the development and operation of JunoCam, an outreach camera that will involve the public in planning images of Jupiter.
Five MILLION Planet Four classifications! We have 4 people on our P4 science team – I cannot even begin to calculate how long it would have taken us to do the work that you, our fabulous volunteers, have done. Because of your contributions we are analyzing all this data, getting results, rather than still doing the measurements on individual HiRISE images.
Just the other day one of my colleagues and I were discussing our early efforts to automate the identification and sizing of fans. We were at the time perplexed by how to train the code to recognize the same fan when the contrast had changed, recognizing that fans could come from the same source yet point in different directions, what to do when a hazy atmosphere lowered the contrast of all the fans in the scene and so on. The human eye-brain connection is so incredibly powerful that we overcome these challenges without even realizing that we have faced a puzzle!
And in the process of helping us I have also realized that you have built a community. We all are now members of the P4 science team. With that in mind I’d like to acknowledge the wonderful contributions of our moderators, and how the interplay between Meg, the moderators, and all of the rest of us has lent a joyful note to the whole undertaking. To the Talk community and all Planet Four volunteers , you might have been alone when we passed the 5 million mark, but all of us are celebrating together around the world!
