SpaceX has successfully launched its previously used Block 5 variant of its Falcon 9 rocket.
Just three months separated today's mission from the first launch of the same Block 5 booster. "Ironically, we need to take it apart to confirm it does not need to be taken apart".
After a final lightning-fast series of computer checks, the 229-foot-tall rocket was released from pad 40 at the Cape Canaveral Air Force Station, quickly accelerating skyward atop 1.7 million pounds of thrust.
The satellite is expected to reach its orbit at about 32,000 kilometers above sea level within the next 11 days before its full operation in the third week of September. Rather, it really is the case that the first Block 5 reuse is one of the most important things ever done by SpaceX.
They say "third times a charm", but that expression is usually reserved for success after failure. Built by Lockheed Martin, the satellite was 18 years old, operating three years past its design life.
