Leveraging Cross-Industry Knowledge To Improve The Design Of Space Systems, Jay Lewis, Christian M. Fuchs Aug 2024

Leveraging Cross-Industry Knowledge To Improve The Design Of Space Systems, Jay Lewis, Christian M. Fuchs

Small Satellite Conference

There are valuable satellites that fail early and almost none have been repaired or investigated. Other industries benefit from feedback loops that use failure analysis to accelerate design and manufacturing improvements.17 Historically the cost of a repair mission would be so high it wouldn't be considered. The cost of space debris mitigation missions can be reduced by leveraging the learning other industries have experienced. Lowering the cost of repair missions will enable more debris mitigation, learn more about why missions failed, and lead to fewer failures and lower costs.

Many space programs rely on outdated processes that increase costs, …

Suncet: The Sun Coronal Ejection Tracker, James Paul Mason

Small Satellite Conference

The Sun Coronal Ejection Tracker (SunCET) is a CubeSat funded by NASA Heliophysics dedicated to figuring out how coronal mass ejections (CMEs) are accelerated. There are SO MANY theories and models about how stored up magnetic energy can be released to force massive amounts of plasma to escape its magnetic confinement. Perhaps the background magnetic field falls with height just steeply enough that even a small random expansion of a flux rope is enough to let it fly free (torus instability model). Or perhaps the boiling motion at the surface of the star twists the coronal magnetic field so much …
