Abstract: In February 2017 the Isinglass auroral sounding rocket mission
will launch two rockets into two separate nightside auroral
events from Poker Flat Alaska.  The Isinglass mission (Ionospheric
Structuring:  in situ and groundbased low altitude studies) is
designed to collect two case studies of multipoint in situ 
plasma data in the context of an array of groundbased observations.
Each of the two vehicles will deploy an array of 6 payloads,
including 4 low-resource ``Bobs,” to make observations of structuring
in plasma flows.  The array of payloads will cover an area
of a few km, and the camera data will be used for context in
space and time, and to constrain our understanding of the
plasma between the in situ observation points.  With Isinglass
we look to determine how observed spatial gradient scale 
lengths of ionospheric structures are related to the characteristics
of their auroral drivers;  and, via  modelling of the observed events,
to see how these spatial gradient scale lengths affect magnetosphere-
ionosphere coupling processes.
