Space Stats

Control system malfunction - control lost after 57 sec.

Fourth Stage failed to ignite.

Launch vehicle disintegrated 88 seconds after liftoff.

Third Stage failed to ignite.

Improper third stage trajectory - unknown cause.

Premature second stage cutoff. Unknown cause.

Radio contact lost

Vehicle exploded at ignition.

First stage exploded after 77 sec, at an altitude of 15.2 kilometers, caused by a turbopump gearbox failure.

Radio contact lost

First Stage collided with upper stages. Second Stage ignited in wrong direction.

Vehicle exploded after 0.75sec.

Stage failed to ignite

One first stage motor failed to ignite

Launcher disintegrated 93 seconds after launch due to longitudinal resonance of strap-ons.

Insufficient 2nd stage thrust - unknown cause.

Launcher disintegrated 104 seconds after launch due to longitudinal resonance of strap-ons.

Second stage shut down 10 seconds early due to incorrect information from an accelerometer measuring incremental velocity. The launch vehicle produced insufficient velocity for the probe to escape Earth’s gravity. The probe did, however, reach an altitude of 114,750 kilometers before falling back to Earth.

Upper stages separated prior to burnout. Structural failure after 149 sec due to vibration disturbances generated by the spinning payload.

Third stage ignition unsuccessful.

Core engines shut off at 245 seconds into the flight. Cause was a loss of lubrication to the hydrogen peroxide pump.

Main booster engine shut down 4 seconds earlier than planned due to premature propellant depletion. Probe reached a maximum altitude of 102,322 kilometers.
