An Attempt to Catch Up with the Super Heavy Stage
Mounted on the launch tower from which the Starship is launched, this Mechazilla features mechanical arms that can open and close at various altitudes. These arms will serve as “clamps” to catch the Super Heavy stage before it touches the ground and hold it a few meters above the surface. Additionally, these arms will be capable of pivoting, allowing for the repositioning of the stage onto the launch platform. Furthermore, their extensive range of movement will enable them to recover a nearby Starship, facilitating its attachment to the Super Heavy.
Concerning the heat shield, which has been enhanced with a secondary shield positioned behind the primary shield, SpaceX aims to ensure its functionality throughout the round-trip flight. The company is focused on avoiding the issues encountered during the previous test flight, where the thermal stresses experienced during atmospheric reentry were significantly higher than anticipated, resulting in damage such as tiles being torn off or a flap that was partially melted but still operational.
A Controlled Dive for Starship
In this context, there are currently no plans to recover the Starship on land until the heat shield has been qualified. There is a significant risk that a compromised shield could hinder precise landing or make the vehicle challenging to control. SpaceX aims for at least three successful splashdowns of the Starship in water before attempting to return it to the launch site. Elon Musk estimates that the likelihood of this improved heat shield remaining intact is probably better than 50%, possibly reaching 60 or 70%. In the meantime, the Starship is executing controlled dives into the ocean.
An Attempt to Catch Up with the Super Heavy Stage
SpaceX’s innovative approach to rocket recovery is setting new benchmarks for aerospace engineering. Installed on the launch tower, the Mechazilla system features advanced mechanical arms designed to grasp the Super Heavy stage during descent. These arms function like high-tech vices, capturing the rocket a few meters above the ground before gently guiding it back into position on the launch support. The ability of these arms to pivot adds an extra layer of versatility, enabling them to also recover a nearby Starship, facilitating a seamless integration process.
- Mechazilla’s Features:
- Mechanical arms capable of opening and closing at variable altitudes
- Pivoting capability for repositioning
- Recovery functions for both Super Heavy and Starship
The Super Heavy rocket, regarded as one of the most powerful stages ever constructed, requires a robust recovery system. SpaceX is focused on minimizing ground impact forces and orchestrating a flawless capture operation. Parallelly, the heat shield has undergone enhancements with a secondary shield added, aimed at safeguarding against thermal stresses that previously led to vehicle damage. The crucial goal? To maintain functionality throughout the entire round trip, elevating the reliability of future launches.
A Controlled Dive for Starship
Given the challenges faced during prior tests, SpaceX has currently opted against recovering the Starship on land until the heat shield is fully certified. The risk posed by potential shield damage could jeopardize precision landings and create control difficulties. In the interim, the strategy involves executing controlled oceanic splashdowns.
- Current Recovery Strategy:
- Minimum of three successful splashdowns before attempting land recovery
- Focus on ensuring heat shield integrity
- Controlled maneuvers for safer landings
Heat Shield Improvement Plans
The upgraded heat shield aims to mitigate high thermal stress during atmospheric reentry. The previous launch displayed issues such as detached tiles and damage to critical components, including flaps. With a focus on achieving at least a 60-70% chance of success in maintaining shield integrity, SpaceX is determined to refine this pivotal technology.
