Labor Day Research Update

Fun fact: 40 years on September 5, 1977, the first Voyager probe was launched. PBS did a fun documentary in honor of it (you may have trouble watching it in Canada).

My apologies dear readers, particularly the one that counts 😉, I had meant to get this out at the end of the week last week. Unfortunately, and somewhat fortunately, I was all over the place Thursday and friday, visiting my sister, then my mom, then we both took a two hour trip (thanks to her for driving) so I could see my grandparents (the drive back was very slow due to traffic from Irma evacuees). That was great because a delayed flight made it impossible for me to visit them during fourth of July and it had been since Christmas since I saw them last. But, in all the chaos, it completely slipped my mind until late last night when I was getting on my greyhound back from Detroit that I had forgotten to update you all.

I don’t have a lot to talk about. It boils down to two things: trying to make sure my mosaic is complete, and mapping all of Titan’s craters. Neish et al. 2016 presented a map of Titan’s craters, at which point the total crater count reached ~75.

I attempted to repeat this, without referencing this map or the catalog of known and suspected craters during my initial overview. A lot are not visible at this scale, but my current estimate is at 85 craters. I’ve started to go back and compare mine with this map and the catalog to see if there were a couple obvious ones I missed. There were, but there were also those I didn’t agree with. Which brings me to the next step on how to move forward.

Which really just consists of a few questions:

  • How do I check that what I’ve done is reasonable?
    • Can I even do that?
  • Should I go through the entire list of previously cataloged craters to make sure I checked all the areas?
  • I did not see any craters near the poles; I don’t understand how anyone can.
    • Should we expect craters nearer poles to be warped circles due to projections? My map is mostly complete. I have images in some areas where the Neish et al 2016 does not, but I’m still missing others.

The top right of the mosaic in particular. I checked my list of BIBQI images and I have the same images as Alyssa. I did have some BIBQH images missing that she has. Although, a lot of these are duplicates of BIBQI images. So that’s where I am at with that, but I could still use some suggestions.

I am going to keep trying to find those missing images, but then I’m going to start looking at the crater morphology unless instructed on how to improve my crater population.
