Results...?

So as you know, I have been working hard at my master's thesis. Well, recently, there was a break through...I think. I found a dependence of electron temperature on RAM angle (the angle between the Cassini spacecraft and the ram point on Titan). It is quite linear and it exists for a certain range covering most of Titan. You can see this below:

If you look at the plot on the top right, you will see the linear dependence from about 40 to 130 degrees ram angle. This was an interesting result. Many more plots were made to attempt and reject this but it seems to show up in most of them. Now this is where it gets a little more interesting. While making all these other plots, I seem to have stumbled upon information that confirms the work of two others that are also working on Titan data, mainly that there is a 'hump' in density around 1050km and that density and temperature have an inverse relationship. The positive note from this is that my data gathering methods are correct and that this phenomenon isn't due to me biasing the data  or making plots of the wrong thing. So...yay me! But now I have a few more things to this week to attempt to investigate this result and see if anything can explain this phenomena. So one hurdle past, another lays before me. Oh well, that is science...always more to do.

In other news, I found four more PhD positions to apply for in Stockholm so that brings the total that I will apply for to eight. So far two are finished, I am waiting on one recommendation letter to complete two more and then these other four are not due until the beginning of next month. Which reminds me, I need to ask one of my references to remove specific information from the recommendation he wrote so that I can use it to apply for these new positions that I have found.So if we were to number the positions that I am applying for (by way of due date) and then place them in order of preference, you would get:
1 3 2 5 6 7 8 4.

Now that shouldn't make too much sense, but more or less means I want to stay in Uppsala...if they will have me. For any that are thinking of applying against me...good luck, but don't try too hard, I really want the position. :)

Anyway, I have enough work to last me until the end of June and the longer I wait, the more I will have to do later. Have a good day and see you around Ångstrom.

Plots, plots, everywhere...

So in my last post, I mentioned my thesis. Now I admit I got off to a slow start, but that was because I had to teach myself MATLAB. However, once I got the hang of it, I am pumping out more results than my professor can keep up with. In fact, last week, he asked me to stop seeing him so he could other things done. I was too excited. So what I did was to re-organize all the data. I took the ephemeris data from Cassini and matched it to available Langmuir probe data so we had a location for each measurement. I then added solar coordinates to the data and from that calculated the solar zenith angle and the RAM angle (this requires explanation which I will not get into). Anyway, after all that, I created a data file that contained all the information. So for each flyby, there is a data file that contains all the relevant information. Once this was done, I could simply write simple commands and produce plots for anything in any number of dimensions. I attempted to put a rotating 3D plot for you to view but it didnt quite work out. So instead I just put up an example plot below.

This is the first flybys from Cassini. There will be a few more added next week, but it is basically a map (altitude not shown) of all flybys below a certain altitude. This plot doesn't really give that much insight into what is happening, it is more of a map than anything else.

In other news, our SNSB proposal was rejected. :( Oh well, it was a great learning experience and we gave the professionals a run for their money. But thanks to the feedback I received, I know the weak points of our proposal and now have experience in writing them so the next one will surely go better.

And lastly, PhD positions. Since I am oh so close to finishing up my master's, I have to think about the future. There are several positions here in Uppsala, and I plan on applying to all of them (I already have applied to one, and will do the other two this week --> my professor is out of town and told me to take a break). There is also one in Norway which I plan to apply to. I have gotten almost all of references and now have to write my letters (basically a personal statement) and update my cv. Busy few months ahead with this and thesis and a homework assignment I still owe. But I can do it. And besides, if I don't, someone else will and I won't have the opportunity to contribute. That is unacceptable.

Until next time...

Is it hazy in here....

I have been working on my thesis non-stop for the past 8 weeks and it is a mixture of fun, work, and rewarding results. When I say rewarding results, I mean for me. Though I have had worked with some programming before, to be able to work on my thesis required me to learn a new mathematical program from scratch. The end result...well see for yourself.

Now that isn't going to make sense to too many people but it is a result of measurements from the Cassini spacecraft in orbit around Saturn. This is a Titan Flyby. I won't get into the gory details but it is a pretty picture...no? I am creating a temperature distribution map around Titan for physicists and chemists who want to better understand its properties. It is too early for me to make any meaningful conclusions but the work keeps flowing in and I am actually enjoying it immensely. Which is why I say it is rewarding for me. I have learned new skills and am getting a better picture of how space physics works and it seems to be a great place to be. I am lucky to have found Uppsala University.

So let's take a moment and reflect back over the time since I last wrote. I mentioned that I had a presentation for my Space Mission Design class. That presentation went excellent. As a group, we gave a satisfactory oral presentation but we really shined after, during the question and answer session. It allowed each group member to answer questions about their specific portion of the project and we fielded all types of questions and preformed exceptionally well. In fact, as a result of the strength of our report, we actually submitted to a national call for ideas from the SNSB. There were 12 entries, with MINIONS being the best...naturally. You can see the other entries on the SNSB site here. We recently received our submission review, no decision has been made. Our review was better than expected. I even asked a few professors to take a look at our critiques and give their feedback on it as well. I mean, seriously, I just walked up to a professor and said, "Could you take a minute and tell me what you honestly think?" And that was it, they took the time to read through and give me feedback. Having access to these people and they are so generous with their time. It is definitely something that really increases the joy of being here.

Also, I have finished my lab work for NASA's MMS mission. All the probes have been measured, data analysis performed, and they were then ranked to select only the highest quality probes. I at first was under the impression that such small deviations would not be noticeable, but I was wrong. I am wrong a lot, but it's ok. It means I am learning. Anyway, after all the work was done, I got to sit down and pair the probes together in groups of two, then four. Yes, I actually got the opportunity to select which probes would fly in space. I inspected them, measured them, and then had the ability to say what does and what does not fly into space. There is nothing sweeter for me than the things I have done here just in the past three months. It is a real shame that I am almost finished.

Well now I am off to the wonderful world of Astronomy and Space Physics. There will be much more to say in the next week or so b/c my thesis is constantly evolving with time and the results will shed new light on our understanding of solar system bodies. Yeah, I am lucky....I already know.
