Mission Summary

  • The goal of the program is to construct and demonstrate the potential scientific applications of two high resolution (~120m) ocean color instruments to be carried by two 3U (10cm x 10cm x 30cm) CubeSat Platforms:
    • ACC Clyde (Scotland) provided the CubeSat bus named SeaHawk
    • Cloudland Instruments (California) provided the Hawkeye Sensor
  • The Program was funded in 2014 by the Gordon and Betty Moore Foundation
  • The program is administered by Dr. John Morrison – UNCW
  • NASA provided “advice and review” during the development phase and with formal NASA/HQ Space Act Agreement (2017), will provide services for the collection, processing, calibration, validation, archive and distribution of the data.
  • A second Moore Foundation grant was awarded in 2017 to provide the funds for another commercial launch for the second CubeSAT and operations of both spacecraft and instruments for a duration of 2 years each.
  • In 2021, the University of Georgia Skidaway Institute of Oceanography joint the team, Dr. Sara Rivero-Calle's team will be co-leading the Science Program and Mission Management.
