Supernovae are extreme environments, with energies far beyond what we can create in laboratories on Earth. Almost all of the explosion energy (99%) is emitted in the form of neutrinos with energies on the order of MeV, which can then serve as probes of the conditions of the system. As the shock propages through the material surrounding the star, high energy neutrinos (GeV-TeV) can also be produced. IceCube, a detector embedded in the ice at the South Pole, will make a precision measurement of the MeV neutrino rate from the next galactic supernova, giving us an unprecedented look at the inner structure of the exploding star, and will be sensitive to the high energy emission. Future detectors, such as Hyper-Kamiokande, will give even more details of the explosion, such as the neutrino energies and supernova direction, and will allow us to push the observable horizon beyond our own galaxy. This talk will outline the status of the IceCube and Hyper-Kamiokande experiments, as well as discuss what physics we expect to extract using supernova neutrinos.
