Re-entry nose-cone heat transfer experiment; photography; atmosphere research. Launched at 1455 local time. Reached 232 km.
The 28th R&D firing was from AMR at 1919 hours EST to a pre-calculated range of 1,299 nm. The flight successfully accomplished all primary and secondary missions. The nose cone impacted 0.65 nm short and 0.52 nm right of the intended target. References: 439 .
The escape stage entered parking orbit but the main engine cut off just 0.8 s after ignition due to cavitation in the oxidiser pump and pump failure.. The payload attached together with escape stage remained in Earth orbit. References: 1 , 2 , 5 , 6 , 64 , 65 .
