Common Misconceptions

1. The SpaceX Kestrel is a fully reusable rocket.

Contrary to popular belief, the SpaceX Kestrel is not a fully reusable rocket. Although SpaceX is known for its reusability efforts with rockets like the Falcon 9 and Falcon Heavy, the Kestrel is not designed to be reusable.

• The Kestrel’s design primarily focuses on providing high performance and reliability for orbital launch missions rather than reusability.
• The lack of reusability allows SpaceX to optimize the rocket for mission-specific requirements without the need for refurbishment after each launch.
• This misconception may arise from SpaceX’s association with reusable rockets but does not apply to the Kestrel specifically.

2. The SpaceX Kestrel is the main rocket used by SpaceX for all types of missions.

It is often mistakenly assumed that the SpaceX Kestrel is the primary rocket used by SpaceX for all types of missions. However, this is not the case, as SpaceX employs a diversified fleet of rockets.

• While the Kestrel is an important and reliable rocket in SpaceX’s lineup, it is primarily used for smaller payload launches.
• SpaceX’s Falcon 9 rocket is the workhorse of the company and is used for a wide range of missions, including satellite deployments, cargo resupply to the International Space Station, and even crewed missions.
• This misconception may stem from limited public awareness of SpaceX’s full rocket portfolio.

3. The SpaceX Kestrel is capable of sending humans to space.

Another common misconception is that the SpaceX Kestrel is capable of sending humans to space. However, the Kestrel is not designed or equipped for crewed missions.

• Unlike rockets like the Falcon 9 or the upcoming Starship, which have crewed capabilities, the Kestrel is a dedicated cargo-launching vehicle.
• The lack of crew accommodations, life support systems, and other safety measures necessary for humans in space make the Kestrel unsuitable for manned missions.
• This misconception may arise from confusion between different rockets in SpaceX’s fleet or a general lack of understanding about distinct rocket capabilities.

4. The SpaceX Kestrel is the only rocket capable of performing specific types of satellite deployments.

Some people mistakenly believe that the SpaceX Kestrel is the only rocket capable of performing specific types of satellite deployments. However, there are various rockets available for different satellite deployment needs.

• While the Kestrel is highly reliable and efficient, other rockets like the Falcon 9 or the upcoming Starship have the capability to handle diverse satellite deployment scenarios.
• SpaceX, as a company, offers flexibility in launching payloads by utilizing different rockets depending on the unique requirements of each mission.
• This misconception likely stems from limited awareness of the broader capabilities and flexibility of SpaceX’s rocket fleet.

5. The SpaceX Kestrel is related to the Falcon 1 rocket.

There is a misconception that the SpaceX Kestrel is somehow related to the Falcon 1 rocket. However, these two rockets are not directly connected.

• While both rockets were developed by SpaceX, they are distinct in terms of design, purpose, and capabilities.
• The Kestrel is a liquid-fueled upper-stage rocket engine, while the Falcon 1 was a two-stage liquid-fueled orbital launch vehicle.
• This misconception might arise from the fact that SpaceX worked on both projects, but they are separate entities.
