SpaceX is making significant strides with its Starship prototype, SN24, which recently began cryogenic testing and static fires. This prototype is unique because it includes a small door in its cargo bay, specifically designed for deploying the next generation of Starlink satellites. These satellites are larger than their predecessors and cannot be launched using the Falcon 9 rocket.
The inclusion of this door highlights SpaceX’s urgency to deploy these new Starlink satellites. Traditionally, SpaceX uses unconventional test payloads for new rocket launches, such as a block of cheese or Elon Musk’s Tesla Roadster. However, with Starship, they are focusing directly on launching their own satellites, indicating a shift in strategy.
Elon Musk has mentioned that a large cargo bay door is planned for future Starship models. For now, SpaceX has developed a system similar to a pez dispenser to deploy the satellites. This mechanism, inspired by industrial pallet stackers, uses electric systems to stack and push the satellites out through the small opening.
Deploying satellites in orbit presents unique challenges due to microgravity. Unlike on Earth, gravity does not naturally pull the satellites down. SpaceX’s system will drive the satellite stack to the bottom of the bay, where another mechanism will push them out. This design can accommodate around 54 Starlink satellites, similar to the Falcon 9’s capacity, but the new Starlink 2 satellites are much larger, measuring 7 meters in length.
Initially, Starship was expected to launch 120 satellites at once, suggesting either an increase in satellite size or potential future enhancements in Starship’s payload capacity. The design also allows for reverse operation, facilitating the loading of satellites into Starship, which would be challenging without a large opening.
At the Boca Chica site, a new structure has been identified as a clean room for stacking Starlink satellites into Starship. This structure aligns with Starship’s opening and includes a door for worker access. SpaceX’s innovative approach to space operations continues to evolve, even as they face challenges in satellite deployment.
SpaceX is currently finalizing Booster 7, which will launch SN24. They have received FAA approval to begin launching Starship and Super Heavy, but a launch license is still pending. A launch is anticipated from September onwards, though timelines can be unpredictable. When the launch occurs, SpaceX is expected to provide extensive camera coverage, as seen in previous missions.
SpaceX’s new approach to deploying Starlink satellites showcases their commitment to innovation and efficiency in space operations. As they continue to refine their techniques and infrastructure, the future of satellite deployment looks promising.
Examine the design features of Starship SN24, focusing on the cargo bay door and its role in satellite deployment. Create a presentation that outlines how these features contribute to SpaceX’s strategy for launching larger Starlink satellites.
Engage in a debate about the urgency of deploying the new generation of Starlink satellites. Consider the implications of SpaceX’s shift from using test payloads to prioritizing their own satellites. Prepare arguments for both the benefits and potential risks of this strategy.
Using the concept of the pez dispenser mechanism, design your own innovative satellite deployment system. Consider the challenges of microgravity and propose solutions to ensure efficient satellite release. Present your design to the class.
Research the challenges of operating in microgravity, particularly in the context of satellite deployment. Create a report that discusses how SpaceX’s current and future designs address these challenges, and suggest additional improvements.
Based on the information about SpaceX’s current projects and future prospects, predict the next steps in their satellite deployment strategy. Write a short essay discussing potential advancements in Starship’s payload capacity and infrastructure.

The Starship prototype SN24 recently rolled out to the pad to begin its journey of cryogenic testing and static fires, aiming to become the first Starship to reach orbit. This prototype features a unique design, being the first to have a door in its cargo bay section. However, this door is not what many expected; it is a small opening specifically for deploying SpaceX’s next-generation Starlink satellites, which are larger than previous versions and cannot be launched on the Falcon 9.
The fact that SpaceX is already working on this door indicates their urgency to get these Starlink satellites into space. Typically, when SpaceX launches a new rocket, they use unusual or humorous items as test payloads, since satellite companies are hesitant to risk their expensive satellites on untested rockets. For example, SpaceX launched a block of cheese on the first Dragon flight and Elon Musk’s Tesla Roadster on the first Falcon Heavy flight. However, with Starship, they seem to be getting straight to business, as they now have their own satellites to launch.
According to Musk, the large cargo bay door that many anticipated is a feature for future Starship iterations. The current solution involves a system that resembles a pez dispenser, which will deploy Starlink satellites from a small opening in the vehicle. This system was inspired by industrial pallet stackers and will use electric mechanisms to stack and push the satellites out.
One challenge with this system is that in orbit, the satellites will experience microgravity, which means they won’t be pulled down by gravity as they would be on Earth. Instead, a mechanism will drive the satellite stack down to the bottom, where another mechanism will push them out through the opening. SpaceX has provided a visual representation of how this dispenser will work, with the design allowing for around 54 Starlink satellites to be loaded into Starship. This is similar to the number currently launched on the Falcon 9, but the new Starlink 2 satellites are significantly larger, measuring 7 meters in length compared to the previous 3-meter models.
Interestingly, it appears that Starship was initially designed to launch 120 satellites at once, so either the Starlink satellites have increased in size, or Starship’s payload capacity may expand in future prototypes. This design also allows for reverse operation to load the satellites into Starship, as accessing the cargo bay when fully assembled would be difficult without a large opening.
Recently, a mysterious structure was spotted at the Boca Chica site, which has been identified as a clean room for stacking Starlink satellites into Starship. The structure’s opening aligns with Starship’s, and there is a door for workers to enter. It’s still unclear how SpaceX will elevate this structure to match SN24’s height, but they are known for innovating in space operations.
While there are other satellite deployment systems, such as those used on the ISS, SpaceX’s approach is unique and may face challenges. The ISS has a cubesat deployer that allows multiple satellites to be released, which is more efficient than manually throwing them.
As for when we will see Starship’s deployer in action, SpaceX is currently working on completing Booster 7, which will launch SN24. They have received FAA approval to start launching Starship and Super Heavy, but they still need to secure their launch license. A launch is anticipated from September onwards, but timelines can be unpredictable. When the launch does occur, SpaceX will likely have extensive camera coverage, similar to their previous missions.
