SpaceX can be seen recovering its rockets – On Sunday evening, SpaceX’s Falcon Heavy rocket sent two government payloads into space while putting on a spectacular firework show.
The rocket’s two side boosters made a double landing at Cape Canaveral about eight minutes later, thrilling onlookers.
The landings were the 163rd and 164th successful booster recoveries for SpaceX, and thunderous booms could be heard overhead. Due to the need for fuel to get the payload in orbit, the rocket’s centre core was abandoned in the ocean.
One observer in particular managed to film the meticulously orchestrated orbital ballet that lets each rocket successfully land in extraordinarily fine detail.
SpaceX rockets consist of four main parts: the first stage, the second (or upper) stage, an interstage that joins the two, and a payload fairing that protects the satellites or cargo the rocket is carrying.
According to SpaceX, the cost of the rocket is largely comprised of two of those parts, the first stage and the payload fairings, which are both intended for reuse.
A SpaceX rocket goes through a number of procedures after liftoff to make sure the payload reaches the desired orbit. However, as soon as the first and second stages split, the second stage carries on with the payload while the first stage gets ready to return to Earth, where it will either land on land or on a floating platform in the ocean.
As soon as the first stage separates, the booster starts an orbital ballet in which it flips around in midair and ignites three of its engines for a boostback burn that will help it prepare for landing.
The rocket must slow down with three landing burns in order to prevent a crash landing, the first of which is the boostback burn. After then, the booster will release a set of titanium grid fins that are utilised to guide the rocket. When it reenters the atmosphere of the Earth, the vessel will then temporarily restart its engines for an entrance burn.
Then, with the aid of the grid fins, the rocket is steered to its landing location as it ideally touches down gently. The booster’s engines then fire one more time.
When SpaceX recovered its first booster at Cape Canaveral in 2015, it began recovering rockets in this manner.
