Abstract:
Computational science and engineering for design and assessment of
current and future JPL flight projects has emerged as a way to enable
mission success. In this survey talk, I will describe the role of high
performance computation, observing system simulation experiments (OSSEs),
and uncertainty quantification techniques applied to various areas in
science and engineering as methods to address complexity for topics of
importance to JPL.
In the Earth sciences OSSEs allow one to quantify the impact of the
science returned from a mission concept based on design trade analysis
of mission and instrument performance characteristics. This approach
has been used in the numerical weather prediction (NWP) community for
over 40 years, but is now finding it's way to other disciplines relevant
to Earth observational science. Integration of simulation models and
mechanisms for data transfer are an underlying component technology to
this work. JPL is also active in high performance computing applied to
engineering design, such as safe rover traversal, Mars Entry Descent
and Landing, as well as in mission design for geophysical observations
including Earthquake science. An overview of these areas concluding
with mechanisms applied to identify and quantify uncertainties in
engineering systems that cross discipline boundaries will be
discussed.
