The image above shows the 70 m Deep Space Network (DSN) radio telescope, DSS-43, at the Canberra Deep Space Communication Complex (CDSCC). Yesterday’s ADAP described some radio-astronomical observations undertaken with the antenna during a break from its more usual spacecraft tracking, and previous ADAPs have covered the Depot-Level Maintenance period the antenna will be in for most of this year (Image credit: CSIRO/CDSCC/A.
