SpaceX’s Falcon 9 rocket is a reusable launch vehicle designed to transport satellites and astronauts into orbit. One of the most remarkable features of the Falcon 9 is its ability to land its first stage back on Earth, a feat that has revolutionized the economics of spaceflight.
How Does the Falcon 9 Landing Work?
The Falcon 9’s landing process involves several key steps:
-
Ascent: The Falcon 9 launches vertically, carrying its payload into space. The first stage burns its engines to attain the necessary velocity to reach orbit.
-
Separation: Once the payload is deployed, the first stage of the Falcon 9 separates from the upper stage.
-
Re-entry: The first stage begins its descent back to Earth, re-entering the atmosphere and experiencing intense heat.
-
Hypersonic Maneuvers: The stage performs a series of aerodynamic maneuvers to control its descent and prepare for landing.
-
Engine Ignition: Just before landing, the stage reignites its engines to slow its descent further.
-
Touchdown: The stage lands vertically using retractable landing legs, either on a designated landing pad or a drone ship at sea.
Benefits of Falcon 9 Landing
The ability to successfully land the Falcon 9’s first stage has several significant benefits:
| Benefit | Description |
|---|---|
| Cost Savings: Reusing a first stage significantly reduces the cost of launches, as it eliminates the need to build and launch a new rocket for each mission. | |
| Environmental Sustainability: Landing the first stage minimizes the amount of space debris created, reducing the environmental impact of launches. | |
| Increased Launch Cadence: The ability to reuse the first stage enables more frequent launches, allowing SpaceX to meet the growing demand for satellite and astronaut transport. |

- Refurbishment and reuse: The recovered first stage undergoes inspections and refurbishments to prepare it for subsequent launches. Reusability extends the lifespan of the rocket, reducing the need for new hardware.
- Cost savings: By reusing first stages, SpaceX can drastically lower launch costs. These savings are passed on to customers, making space missions more affordable.
- Environmental benefits: Reusability reduces the amount of rocket debris entering the atmosphere, minimizing its impact on the environment.
- Increased launch cadence: The ability to reuse first stages enables SpaceX to launch rockets more frequently, allowing for rapid deployment of satellites and other payloads.
SpaceX Falcon 9 Launch Cost
SpaceX’s Falcon 9 rocket has a launch cost of around $62 million per mission, which includes the cost of the rocket, payload fairing, and launch services. This makes it one of the most affordable large rockets on the market.
The Falcon 9 uses a two-stage design, with a reusable first stage and an expendable second stage. The first stage is powered by nine Merlin engines and can be recovered and reused up to ten times. This significantly reduces the cost of the rocket, as the first stage is the most expensive component.
The launch cost of the Falcon 9 has been declining over time, as SpaceX has become more efficient in manufacturing and launching the rocket. In 2012, the launch cost was around $100 million per mission. However, in 2022, the launch cost had fallen to around $62 million per mission.
SpaceX plans to continue reducing the launch cost of the Falcon 9, with the goal of eventually making it half the price of its current cost. This will make the Falcon 9 even more competitive in the commercial launch market.

SpaceX Falcon 9 Launch Failure
On September 1, 2016, a SpaceX Falcon 9 rocket carrying a satellite for Facebook exploded shortly after liftoff from Cape Canaveral, Florida. The launch failure was caused by a faulty strut in the rocket’s second stage that snapped during flight. The explosion destroyed the rocket and the satellite, resulting in a loss of over $200 million.
The launch failure was a significant setback for SpaceX, which had previously achieved a 100% success rate for its Falcon 9 rockets. The company suspended all launches while it investigated the cause of the explosion and made modifications to its rockets to prevent similar failures in the future.
The investigation into the launch failure concluded that the cause was a faulty strut in the rocket’s second stage. The strut was made of a titanium alloy that was not able to withstand the high stresses of the launch environment. The strut snapped during flight, causing the rocket to break up and fall into the ocean.
