NSF approves funding of the IceCube Upgrade
On June 25, 2019, NSF approved full funding to upgrade the IceCube detector, significantly extending its scientific capabilities to lower energies and improving the fidelity of past and future data through better ice measurements. The IceCube Upgrade project will introduce seven strings of optical modules at the bottom center of the 86 existing strings, adding more than 700 new and enhanced optical modules to the 5,160 sensors already embedded in the ice beneath the geographic South Pole.
