WP3 - Prep

Reflecting on my WP2 - I feel like my presentation was a success.
I enjoyed reading the comments, and suggestions. More often than not people loved everything about my presentation. They mentioned my voice project, body language, my breakdown of jargon, and how I seemed confident. My topic was a complex topic, and not easy to explain at all. So I wanted to make sure I did not lose the audience, when using a lot of scientific terms and explanations. Which from the looks of it was a success, because people said they did not know the terms I used initially, but liked my explanations.  Some people suggest that I dive deeper into my research and that it was a bit broad. While others argued that I should just touch the surface due to the time limit. A lot of people found that my research was an interesting topic and liked that I covered it. I do not see many changes I want to make to my project, but I know that as I dive deeper into things, I will naturally start to change and shift my project, but in a good way.

Research Question: How can we apply a gravity assisted trajectory to our current spacecraft that will allow us to conduct a flyby of planets on the outermost parts of our solar system?

Hey everyone, thank you for checking out and reading my blog. 

Elevator Pitch - Acura Project

Me: How are you doing today Professor Okutsu?
Okutsu: Good, and you?
Me: Great! The other day I was reviewing you publication on "Mars Free Return Gravity Assist From Venus" and I was intrigued.
Okutsu: I am pleased to know you read my article
Me: Yes, it just so happens I am an Aerospace Engineer major, and first year student. And I know that your Ph.D. relates to my major.
Okutsu: Yes, it does.
Me: My name is Ptah-Raet Craig, and I have been looking into gravity assist trajectories and flyby missions. I would love if I could work under you in ACURA, if you needed someone with some knowledge of astrodynamics and has read your publications. I am the perfect person, here's my business card, I can email you my resume and course history.
Okutsu: Sure.
Me: Have a great day.
Okutsu: Same to you.

PB2B - Analyze 2 Scholarly Journal Articles

Journal #1 - Orbital Mechanics about Small Bodies

• Scheeres, D. J. "Orbital Mechanics about Small Bodies." Acta Astronautica, vol. 72, 2012, pp. 1-14. (Link)

Journal #2 -

• Paul, SN, and C. Frueh. "Space-Object Charging and its Effect on Orbit Evolution." Journal of Guidance Control and Dynamics, vol. 40, no. 12, 2017, pp. 3180-3198. (Link)

Both of these articles are looking at small bodies and how they react to spacecraft. Small bodies being, asteroids, comets, etc. They both are trying to find a solution to predict how these bodies will react with the spacecraft. The problem being that they would want to avoid satellites or spacecraft getting hit by these objects. Journal 2 is different in the sense that they are looking at how these small bodies at the in different zones of Earth's magnetosphere, while Journal 1 is just looking at objects in general floating in space. Journal 2 looked at currents, plasa conditions, and simulations. While Journal 1 looked at actual spacecraft floating through space. Both articles imposed that small bodies in space are unpredictable and a solution needs to be put in place to prevent these small bodies from hitting important objects in space.
Both journals had relatively the same structure, opening with the abstract, then introduction. They both do some explaining of how they would measure these things, and then they include the results of the matter, and end with a conclusion, followed by the references.

PB2A - Part 1 & 2

Some disciplines that I interesting is Aerospace Engineering, Aeroacoustics, and Astrodynamics. After looking through Penn State Abington's professors, I found a professor that researches Aerospace Engineering, and Astrodynamics. Profesor Okutsu is currently interested in researching astrodynamics and gravity assist. He also designed a number of gravity assist trajectories for NASA's missions. And spent time researching human exploration of Mars.
For starters I find all of these topics equally interesting, due to my love for space and NASA. So picking just one to dedicate time and research in is not a easy pick. As a kid I've always been interested in space exploration, and the laws of gravity. But if I had to pick one I would love to do research in Astrodynamics, just because that is a topic I do not have prior knowledge of, and I love being exposed to new concepts in science. I think it would be a great opportunity for me to get an idea of the different aspects my major of Aerospace Engineering can cover. I would love to dive deeper into my major and personally, Astrodynamics could be the starting point for me.
