France's Eole satellite (launched by NASA Aug. 16, 1971)
would be used by Australian marine biologists to track ocean movements of crayfish larvae, Reuters reported. Biologists would attempt with tracking buoy to solve mystery of crayfish cycle in which crayfish drifted during its plankton stage. Minute crayfish larvae in free-floating stage had been found up to 1100 km (700 mi) from their hatching grounds outside coastal reefs, but there was little information on cur-rents that carried them there.

Now 1 Improved Tiros Operational Satellite (launched by NASA for National Oceanic and Atmospheric Administration Dec. 11, 1970) was adjudged successful by NASA. Mission objectives of placing space-craft in desired sun-synchronous orbit and collecting daytime and nighttime cloud-cover data had been achieved and spacecraft had been officially deactivated Aug. 19, 1971, when attitude control could no longer be exercised.

ITOS-B Improved Tiros Operational Satellite (launched by NASA for National Oceanic and Atmospheric Administration Oct. 21, 1971) was adjudged unsuccessful by NASA. Satellite had failed to reach orbit when pitch-and-yaw attitude control jets began pulsating to counteract tumbling force from leak in 2nd-stage oxidizer system. Jets kept spacecraft in proper attitude until control gas was expended and vehicle tumbled out of control and impacted above Arctic Circle. ITOS-B was to have been placed in sun-synchronous orbit to observe daytime and nighttime cloud cover. (NASA proj off)
