Re-entered 23 Feb 1965

P-11 No. 4302 (NORAD 914, COSPAR 1964-068B) was a US satellite that re-entered Earth's atmosphere on 23 Feb 1965, launched on 23 Oct 1964 on the GAMBIT SV 963 mission. It was operated by NRO / SAFSP as part of the EHH A programme. The spacecraft was built by LMSC/HRBS on the P-11 bus, with a mass of 95 kg. Like most satellites in low orbits, it was gradually slowed by atmospheric drag until re-entry.
