Well, those Falcon 9 landings never get old. Imagine, just over a decade ago the idea of being able to land a rocket upright after it’d been to space seemed crazy. And then SpaceX went and did it.
Following its first successful touchdown in December 2015, SpaceX suffered the occasional mishap with its booster landings, but in recent years it’s well and truly nailed the process.
The Elon Musk-led spaceflight company shared a video (below) this week of its most recent landing, with dramatic footage captured by a camera attached to the rocket showing the spectacular early-morning ride home.
The Falcon 9’s mission started from Vandenberg Space Force Base in California, and involved the launch of 25 Starlink satellites to low-Earth orbit.
This was the 11th flight for the first-stage booster (B1093) supporting this mission, which previously launched SDA T1TL-B, SDA T1TL-C, and now nine Starlink missions.
As the video shows, after deploying the upper stage, the 41.2 meter-tall (about 135 feet) booster returned to Earth minutes later, landing on the Of Course I Still Love You droneship waiting in the Pacific Ocean.
To achieve an autonomous landing like this, a Falcon 9 booster begins by performing a flip using cold gas thrusters after stage separation, sometimes followed by a boostback burn. As it descends, the booster deploys its grid fins to steer through the atmosphere before performing an entry burn to slow down. Finally, it executes a landing burn while deploying its legs for a stable touchdown.
The landings allow SpaceX to reuse its boosters multiple times, reducing the cost of spaceflight and opening access to more companies and organizations.
Just last weekend, another Falcon 9 booster set a new reuse record of 33 flights after launching for the first time in June 2021.
SpaceX has applied what it’s learned from the landings to its much bigger and more powerful Starship rocket, which is expected to take its 12th test flight in March.
