35th International Cosmic Ray Conference, Bexco, South Korea, 10 Jul 2017 - 20 Jul 2017; Proceedings of Science (ICRC2017), 401 (2017). : The IceCube Neutrino Observatory at the South Pole probes the high-energy cosmic-ray sky byinvestigating the muonic and electromagnetic component of air showers measured with IceTopand the in-ice detector. However, more detailed measurements are needed to understand theastrophysics of the high-energy cosmic-ray sky. This, along with the need to mitigate the impactof snow accumulation on IceTop tanks, has given us impetus for further upgrades includingscintillator and SiPM-readout-based stations.Prototype stations showcasing technologicaladvances for the next generation in cosmic ray detection are currently under construction fordeployment at South Pole in December 2017. We describe the physics and the current status ofthe project. : Published by SISSA, Trieste
