CRO B [NASA]
CRO (Chemical Release Observation) were small satellites to perform releases of different chemicals for observation by the IBSS-SPAS satellite.
The small satellites were powered by solar cells and deployed a radar reflector on a boom.
CRO A released 27.2 kg monomethyl hydrazine, CRO B released 23.6 kg of UDMH and CRO C released 6.8 kg of nitrogen tetroxide.
Data from these observations assisted SDIO in characterizing the signatures expected from liquid fuel clouds escaping from damaged ICBM boosters.
CRO A, B and C reentered on 13 May, 12 May and 14 May 1991 respectively.
