On January 9, 2017, William Ellett and Lamar Hawkins, of the GHRC DAAC’s data processing and management team for the Lightning Imaging Sensor to be deployed to the International Space Station (ISS LIS), participated with the LIS science and engineering team in a simulation activity for the STP-H5 (Space Test Program-Houston 5) package, which contains the ISS LIS. The successful simulation involved use of proper voice protocol to ask the STP-H5 Payload Rack Officer to enable commanding for LIS, to issue the LIS instrument reset commands, and to verify that those commands were sent.
