“A year in the life of a former ACES student” (or “computational tools 
used in the space sciences”)

This talk will give a rough chronological summary of space science 
computational tools I’ve used in the past
year as I’ve transitioned from an ACES student at BU to a new position 
at The Aerospace Corporation. I will
first describe observations of low-energy space plasma and fields, and 
the widely adopted formalism for
understanding them, magnetohydrodynamics. In this regime, simulations 
have proven effective in characterizing
the large-scale morphology and dynamics of the Earth’s magnetosphere, 
and I will use examples from my thesis
to support this view.

After finishing my degree and experiencing a few other life-changing 
events, I took a position with the Aerospace
Corporation in Chantilly, Virginia. I will briefly describe the 
high-energy environment of the Van Allen radiation belts
in the inner magnetosphere, the effects that the space environment has 
on spacecraft and highlight what Aerospace is
doing to mitigate these effects. Finally, I will describe one particular 
project that I’ve contributed to while at Aerospace,
for which I was well positioned due to my ACES computational training.
