SpaceX is enhancing the Starship with landing legs to improve landing reliability and efficiency for military and lunar missions, while potentially moving away from the Mechazilla catch system
Questions to inspire discussion
Strategic Importance
🚀 Q: Why are landing legs crucial for SpaceX's future missions?
A: Landing legs are essential for military contracts and lunar missions, enabling rapid response science drops on asteroids and emergency payload deliveries to orbit, while providing a necessary backup for missions where catching the booster isn't feasible.
🌕 Q: How do landing legs impact Starship's lunar mission capabilities?
A: Landing legs are critical for NASA's Artemis 3 mission in 2027, allowing the Starship HLS variant to land on unprepared lunar surfaces where the catch system isn't available.
Engineering Challenges
🛠️ Q: What are the main engineering challenges for Starship's landing legs?
A: Starship's landing legs must handle the huge impact force of the ship's 150-200 ton mass at 5 m/s velocity when landing on the Moon or Mars, while also managing shear and compressive stress on uneven terrain.
🔧 Q: How do landing legs affect Starship's design and performance?
A: Landing legs add significant weight to Starship and pose substantial engineering challenges, requiring a balance between reliability, stability, and rapid reuse capabilities.
Military Applications
🪂 Q: How are landing legs relevant to military cargo transport missions?
A: Landing legs enable Starship to perform military cargo transport missions around the world, landing on unprepared surfaces where the catch system isn't an option, making them essential for global logistics.
🏝️ Q: What is the significance of the Johnston Island project for SpaceX?
A: The Rocket Cargo Vanguard program on Johnston Island provides SpaceX with the perfect opportunity to fine-tune Starship's landing legs for military applications and global cargo transport.
Key Insights
Starship Landing Capabilities
🚀 SpaceX's Starship will likely be equipped with landing legs this year, enabling it to land anywhere on any terrain across Earth, preparing for the HLS variant for Artemis 3 in 2027.
🌎 The Mechazilla landing method is being scrapped as Starship will soon be able to land anywhere, making it instantly reusable and reducing turnaround time between launches.
Extraterrestrial Applications
🌕 Landing legs are essential for landing on extraterrestrial surfaces like the Moon and Mars, which are unpredictable, rocky, and uneven, unlike controlled landing zones on Earth.
Military and Rapid Reusability
🚁 Mechazilla remains important as a launch tower but not for catching Starship, as landing legs are crucial for military cargo transport missions around the world on unprepared surfaces.
🔄 Landing legs enable rockets to touch down on solid ground or drone ships, making rapid reuse a reality and supporting SpaceX's vision for lunar and Martian missions.
⚡ Mechazilla is crucial for rapid reusability and launch cadence, enabling SpaceX to speed up the entire process by catching Super Heavy directly and placing it on the launch mount.
