What went wrong with Ariane 5?
On 4 June 1996 the maiden flight of the Ariane 5 launcher ended in a failure. Only about 40 seconds after initiation of the flight sequence, at an altitude of about 3700 m, the launcher veered off its flight path, broke up and exploded.
What was Ariane 5 carrying?
As the central element of Ariane 5, the core cryogenic stage serves as one of the launcher’s key propulsion systems. It carries a propellant load of 132.27 metric tons of liquid oxygen and 25.84 metric tons of liquid hydrogen to feed the stage’s Vulcain main engine.
How much does the Ariane 5 cost?
$177 million
That’s a steep discount from the $177 million price tag for the Ariane 5. SpaceX’s website previously listed the cost of a Falcon 9 launch at $62 million. But CNBC noted in 2020 that the United States Air Force contracts paid around $95 million per Falcon 9 launch.

How overflow led to the explosion of an Ariane 5 rocket *?
It turned out that the cause of the failure was a software error in the inertial reference system. Specifically a 64 bit floating point number relating to the horizontal velocity of the rocket with respect to the platform was converted to a 16 bit signed integer.
Why was the Ariane 5 chosen for this mission?
What causes Ariane 5 project failure briefly relate explanation in software crisis?
The failure of the Ariane 501 was caused by the complete loss of guidance and attitude information 37 seconds after start of the main engine ignition sequence (30 seconds after lift- off). This loss of information was due to specification and design errors in the software of the inertial reference system.
