The ANITA-4 balloon experiment launched on December 2nd 2016, and circled almost 40km above the ice of Antarctica. ANITA searches for the intense radio pulses produced by ultra-high energy neutrinos interacting in the ice below.

The image below shows the flight path of the ANITA-4 payload, superimposed on a map of the Antarctic rock or seabed elevation (from BEDMAP2).
