Abstract: U.S. Space Force (USSF) Space and Missile Systems Center (SMC) project to develop and demonstrate an Electro-Optical / Infrared (EO/IR) LEO-based cloud characterization solution that supports U.S. warfighter operations. During the first phase, the team (ASTRA, STC, and LM) are building a prototype system that includes an 8-channel IR camera system for cloud measurements, the spacecraft, and the ground system which includes mission operations, mission data management, product generation and quality validation, and distribution. The Rapid Revisit Optical Cloud Imager (RROCI) will utilize commercial off-the-shelf systems to produce cloud characterization products, provide theater weather, and comparison of payload outputs to existing satellite data from a 12U satellite that meets USSF mission requirements. The objective is to create a constellation of imagers to replace the cloud characterization capabilities of DMSP. Launch is currently scheduled for Jan 2022.


Mr. Hal Bloom is the Group Vice President for Science and Engineering for the Science and Technology Corporation (STC) where he has responsibility for over 200 FTE on government contracts at NASA and NOAA involved in Earth / Space Science, engineering and hardware fabrication. He is currently the Deputy Mission manager for the DoD Space Force Earth Weather Satellite (EWS) ASTRA team Rapid Revisit Optical Cloud Imager (RROCI), with responsibilities in mission systems engineering, science algorithm development, and build of the ground segment.Hal is a former NOAA employee. He was the GOES-R and NPOESS satellite Deputy Program Manager with the responsibility in both programs of managing a multiple agency (e.g. NASA, DOD, NOAA) workforce in meeting the technical, schedule and cost requirements of mission space and ground system development for these two large systems. Earlier, Hal was the Payload Manager for NOAA/NASA of the NPOESS/NPP instrument development and engineering activities. Hal also led design and development as Instrument Manager of the NPP Cross-Track Infrared Sounder (CrIS). Before his NOAA experience Hal led a team in the development of the initial CRIS and VIIRS algorithms for the exploratory NPOESS and NPP mission products. Also, in private industry Hal led a team of researchers to improve weather forecasting models by insertion of improved algorithms and products derived from the NOAA operational GOES and POES satellite systems.
