- Spacecraft 14
- Max Q escape and impact test. Purpose was to demonstrate
primarily the structural integrity of the highest dynamic pressure
anticipated during an Atlas launch for orbital flight.
- March 18, 1961, Wallops Island. 19 seconds after launch, the
escape tower fired prematurely. The signal to initiate an abort
was given and the launch vehicle-adapter clamp ring was released.
However, the spacecraft remained on the launch vehicle since the
escape motor was already expended. Separation was then effected
by using the retrorockets but this command was transmitted before
the flight reached its apex, where separation had been planned.
The separation was violent.
- Altitude: 7.7 statute miles
- Orbits: 0
- Duration: 0 Days, 0 hours, 23 min, 48 seconds
- Distance: 18 statute miles
- Velocity: 1,783 mph
- Max Q: 1,580 psf
- Max G: 8
- The parachutes deployed at 40,000ft and after recovery the
spacecraft actually incurred only superficial structural damage.
The spacecraft was later used for the Little Joe 5B (LJ-5B) flight
