According to SpaceX CEO Elon Musk, the space company will attempt something
very different to recover its massive Super Heavy booster after it launches.
“SpaceX will try to catch largest ever flying object with robot chopsticks,”
Musk tweeted early Monday morning.
He was referring, of course, to the giant robotic tower SpaceX is building
to catch the primary rocket stage after it gives the company’s Starship
spacecraft a boost into orbit.
True to character, Musk reasserted his penchant for classic movies, adding a
link to a clip from the 1984 hit “The Karate Kid” that involves catchings
flies with chopsticks.
“Success is not guaranteed, but excitement is!” Musk added.
It’s an exciting moment in the development of Starship. Without its giant
booster, the spacecraft isn’t capable of escaping Earth’s gravitational pull
— but we’re finally inching closer to seeing the first Super Heavy leave the
ground.
Mechazilla
Last year, Musk revealed how “Mechazilla” — the CEO’s nickname for the
structure — will enable a soft landing.
“We’re going to try to catch the Super Heavy Booster with the launch tower
arm, using the grid fins to take the load,” Musk tweeted in December in
response to a fan-made animation. In other words, the two tower arms will
act as a pair of “giant chopsticks” to guide the booster back to the ground.
Musk also revealed earlier this month that Mechazilla will be used to catch
Starship as well — except on the Moon and Mars, where he astutely noted
there isn’t yet any “infrastructure.”
Static Fire
SpaceX completed the construction of the massive 440-foot launch tower late
last month, setting the stage for the first-ever test launch of a Super
Heavy booster prototype.
Last week, the company reinstalled 29 Raptor engines on its first
orbital-class prototype called Booster 4 after a test fitting earlier this
month.
SpaceX will likely attempt a static test fire of the prototype in the coming
weeks. But a full test launch could still be some time away. The Federal
Aviation Administration is still completing an environmental review that
could drag on for weeks if not months.
But when the first Super Heavy leaves the ground, we will certainly be
watching live.
