  BurstCube will detect long GRBs, attributed to the collapse of massive stars,
short GRBs (sGRBs), resulting from binary neutron star mergers, as well as
other gamma-ray transients in the energy range 10-1000 keV. sGRBs are of
particular interest because they are predicted to be the counterparts of
gravitational wave (GW) sources soon to be detectable by LIGO/Virgo. BurstCube
contains 4 CsI scintillators coupled with arrays of compact low-power Silicon
photomultipliers (SiPMs) on a 6U Dellingr bus, a flagship modular platform that
is easily modifiable for a variety of 6U CubeSat architectures. BurstCube will
complement existing facilities such as Swift and Fermi in the short term, and
provide a means for GRB detection, localization, and characterization in the
interim time before the next generation future gamma-ray mission flies, as well
as space-qualify SiPMs and test technologies for future use on larger gamma-ray
missions. The ultimate configuration of BurstCube is to have a set of $\sim10$
BurstCubes to provide all-sky coverage to GRBs for substantially lower cost
than a full-scale mission.
