So far the launch is MUCH more successful than the first. But after separating, the 1st stage booster exploded as it was headed down to the Gulf of Mexico under the power of 3/33 engines. Only 3 engines were supposed to be burning at that point…
There is video of the launch for minutes into the flight, including the explosion.
2nd launch, 3/33 engines.. ok :)
Inform yourself. 3 engines at that stage in the flight was planned. All 33 engines worked as designed through stage separation; 3 are all that are required for boostback and descent.
In this flight, they hoped to test their launchpad redesign as well as the hot stage separation procedure. Both tests were successful, everything after was gravy. This was a successful flight in terms of their objectives.
