SpaceX needs to get a grip on its new Starship rocket in additional methods than one.
This month, CEO Elon Musk outlined how the agency plans to make use of a large arm dubbed “Mechazilla” to maneuver its new Starship rocket into place. Sooner or later, the arm can even assist SpaceX catch the ship after touchdown.
That would assist the agency obtain its most formidable targets, like launching the identical Starship 3 times per day. That, in flip, means it has an opportunity of attaining its aim of a city on Mars by 2050.
It’s one of the formidable options of a spaceflight mission already breaking new floor. The Starship is a fully-reusable rocket able to sending over 100 tons or 100 folks into area at a time. The ship is designed to assist all of SpaceX’s present missions whereas additionally paving the best way for extra formidable plans like a base on the Moon or a metropolis on Mars.
The under-development vessel may grow to be the tallest (394 toes) and strongest rocket (16 million kilos of liftoff thrust) ever to fly. Whereas it’s already set to be a formidable visible sight, “Mechazilla” may make the scene look much more excellent.

SpaceX Mechazilla: why is it named that?
“Mechazilla” is the title Musk has given to the launch tower subsequent to the Starship launchpad. The pad is situated on the agency’s Starbase facility in Texas, the place it goals to host the rocket’s first-ever orbital flight later this yr.
In April 2021, Musk explained on Twitter that, if it had some legs, it might resemble “Mechazilla.” That is almost definitely a reference to the “Mechagodzilla” character from the Godzilla film franchise, which first appeared within the 1974 movie Godzilla vs. Mechagodzilla:
Musk, in fact, is well-known for together with references to science fiction in his firm’s merchandise.
SpaceX Mechazilla: what does it do?
Launch towers for rockets are nothing new. NASA explains that the Fixed Service Structure on the Kennedy Area Middle’s Launch Pad 39A, used for rockets just like the SpaceX Falcon 9 and NASA’s area shuttle, measures round 347 toes from floor to the highest of the lightning mast. It options three swing arms for entry to a shuttle positioned on the pad. It’s superb for emergency exits for astronauts.
However SpaceX is considering greater with the “Mechazilla.” In December 2020, Musk claimed that the agency deliberate to make use of the launch tower’s arms to catch the Tremendous Heavy booster because it returns to Earth.
Some Musk followers have already created animations of their interpretations of the way it may work:
The plan marks a pointy departure from SpaceX’s different rocket reuse efforts. For the semi-reusable Falcon 9, the first-stage booster both returns to Earth on a land-based launchpad or an autonomous droneship within the sea. The rocket fires its engines throughout descent to return to a cease on the pad.
So why not try this then? As a result of, as Musk suggested on August 13, utilizing the tower to catch the booster and ship implies that neither of them wants touchdown legs to assist themselves as they return. The Starship will solely require legs for missions that land on Mars or different planets “till there’s native infrastructure.”
On August 4, Musk also suggested that the tower may transfer the rocket into place.
If the tower can catch the rocket and transfer it again into place onto the launch pad, that would assist SpaceX reuse rockets sooner than ever. The fastest turnaround time for a Falcon 9 booster from the earlier flight to re-flight is 27 days. In March 2020, Musk mentioned that he wished Starship to have the ability to fly three times per day.
If Musk needs to construct a metropolis on Mars by 2050, he may come to rely on that fast turnaround time. In 2019 he estimated that town would require round a million tons of cargo to succeed in self-sufficient standing. If every ship carries 100 tons, meaning SpaceX might want to make 10,000 flights over the following 30 years — or round 333 per yr.
The race is on.
