Elon Musk: @DJSnM @ThePrimalDino 中心核心移动太快返回。 Falcon Heavy 是 3（或 2.5）级火箭，但在地球上完全和快速的可重复使用性需要 2 级火箭。 第一级通过助推和第二级轨道立即返回发射场，直到地面轨道返回发射场返回。

原推：@DJSnM @ThePrimalDino Center core moving too fast return. Falcon Heavy is a 3 (or 2.5) stage rocket, but full & rapid reusability on Earth demand a 2 stage rocket.

1st stage returns to launch site immediately via boostback & 2nd stage orbits until ground track passes back over launch site to return.
