TRS Mk. 1 (ERS)

TRS [TRW]

Payloads:

• TRS 1 (ERS 1): radiation instruments, failed to separate from Samos-E6 5
• TRS 2 (ERS 2): transmitter to study the changes in the Earth's radiation belt as a result of the Starfish high altitude nuclear test detonation over Johnston Island on 9 July 1962, as well as to study the effect of such radiation on solar cells, 0.6 kg; failed to separate from the primary payload which was the KH-4 12 military reconnaissance satellite
• TRS 3 (ERS 3): radiation and micrometeorite studies, carried a cosmic ray experiment as well as an infrared plume experiment, failed to reach orbit
• TRS 4 (ERS 4): radiation and micrometeorite studies, carried a cosmic ray experiment as well as an infrared plume experiment, failed to reach orbit
• TRS 5 (ERS 5): studied the radiation intensity of the Van Allen belts and the radiation damage to solar cells. The payload consisted of 132 solar and photovoltaic cells in various configurations, 0.7 kg
• TRS 6 (ERS 6): studied the radiation intensity of the Van Allen belts and the radiation damage to solar cells. The payload consisted of 132 solar and photovoltaic cells in various configurations, 0.7 kg
• TRS 7 (ERS 7): radiation and micrometeorite investigations, failed to reach orbit
• TRS 8 (ERS 8): radiation and micrometeorite investigations, failed to reach orbit
• TRS 9 (ERS 9): measured radiation damage to silicon solar cell samples. For this the satellite carried 132 n-on-p solar cells of which twenty were part of five experiment samples of four cells each, which included unshielded and shielded cells. There were also shielded and unshielded p-on-n solar cells. Data returned during the 11 days that information was collected, was correlated with data gathered by TRS-5 and TRS-6. The satellite's mass was 1.5 kg.
• TRS 10 (ERS 10): Similar to TRS-9
