1969-083A
The ESRO IB auroral research satellite was launched in Oct 1969 to complement the ESRO IA mission but problems with the Scout left it in low orbit and it reentered after less than two months. The Antares third stage pitched down incorrectly, and the fourth stage underperformed, causing low altitude and velocity. Planned orbit was 400 x 435 km x 86.0 deg.
Mass 85 kg. Size is 0.76 dia 0.96m high, with 2.43m span across the deployed booms. Yo-yo masses of 0.11 kg on 4.70m long wires were deployed.
The E transition section on the Scout carried a LaRC performance experiment to study final stage performance.
