The self-guided rocket exploded into flames as it touched down on a landing pad following a controlled descent.
The test flight had been intended to reach an altitude of 41,000ft (7.7 miles), also powered by three of SpaceX’s newly developed Raptor engines.
This resulted in the opening of an investigation, focusing on the explosive landing and on the Elon Musk-owned SpaceX’s reported refusal to adhere to the terms authorised by the FAA.
And it may have been this that resulted in the SN9 test being scrubbed last week.
Although the FAA made no comment detailing exactly how SpaceX violated terms, it did announce SpaceX had applied to modify its license.
