Hey everybody. Welcome back to the Elon Musk Podcast. This is a show where we discuss the critical crossroads that shape SpaceX, Tesla X, The Boring Company, and Neurolink. I'm your host, Will Walden. SpaceX has begun turning Starship into a fully operational launch system. A Flight 9 reused the Super Heavy booster for the first time, tested a redesigned staging system, and pushed forward with in space payload
deployment. A Flight 10 validated many of those upgrades with a successful mission that returned precise flight data and proved critical improvements to guidance, re entry protection and engine relay capabilities. But even with that momentum, failures in Flight 9 exposed structural weaknesses that had to be solved fast. Now, can Starship become a reliable, reusable platform for lunar and Mars missions without more setbacks?
SpaceX reused Booster 14 for Flight 9 in May of 2025, and the booster launched cleanly, with all 33 Raptor 2 engines performing normally. A number of those engines had already flown, and SpaceX proved they could operate safely again after refurbishment. The mission also trialled A modified hot staging system. Engineers altered the venting system to steer the separation plume more effectively, reducing instability and pressure spikes during stage separation.
That change improved control during one of the most vulnerable phases of flight, and the payload section carried an experimental Starlink deployment system. The ship's guidance system received a complete overhaul to sharpen targeting precisions and the new deployment mechanism and a carousel like ejection approach to it. On paper, the upgrades positioned Flight 9 is the strongest proof that Starship could transition from testing
into regular missions. But cracks emerged fast as Ship 35 accelerated toward orbital velocity. Onboard data showed a methane leak inside the main tank Dome. That slow leak reduced internal pressure, degraded control authority and made it impossible for the ship to maintain orientation. Without stable altitude and attitude, the spacecraft lost control and broke apart on re entry. The booster faced its own critical failure during the final descent.
High aerodynamic forces damaged part of the fuel transfer system and the booster exploded before completing its landing, destroying post flight data that would have informed refurbishment efforts. Postmortem reviews revealed that structural stress points in the boosters fuel lines they weren't strong enough for high speed re entry forces. SpaceX responded by reinforcing the plumbing with additional
material along high load zones. Engineers also redesigned the tank Dome welds, added new leak detection sensors and updated the ejection hardware to fix the jam Starlink Bay. The changes were ready in time for Flight 10. Now, three months later, ship 37 launched and landed in the ocean just three meters off target. That pinpoint accuracy showed clear improvement in the control software and grid fin handling.
Engineers stripped heat shield tiles from one segment of the ship on purpose to test how well the backup thermal systems would hold up. The ship survived re entry despite the induced damage. Now this success proved the Starship's redundancy plan for heat shielding could work under actual stress and the mission also included the 1st in flight
space Raptor relight. That test matters because Starship must relight its engines mid flight to make course corrections during deep space missions, and this relight worked. The success, along with improved engine out handling on the booster, showed that Starship can still land safely even if one or more engines have failed. Flight 10 became the first mission to deploy test payloads
for Starship successfully. The updated deployment system worked as designed, pushing out eight Starlink simulators during orbit. Onboard sensors sent back real time readings on heat exposure, vibration and hull flex, giving engineers the data they need to tweak thermal shielding and structural fashion for future flights. Flight 11 will mark the last use of the current Block 2 vehicle and aims to close out splash down tests for heat shield
segments and upgraded grid fins. This version includes better handling for ocean recovery and new software tuned for predicting wave impact stress. The team wants high fidelity recovery data before moving on to land based catch attempts. Now Flight 12 is important. It begins the Block 3 era of Starship. This version includes the Raptor 3 engine, which provides 20% more thrust, simplified construction, and fewer external components which reduce weight
and improved reliability. SpaceX integrated the hot staging ring into the ship's lower Dome to eliminate excess mass, and the new grid fin arrangement allows for more precise directional control during descent and the payload limit jumps to 140 metric tons. These ships are built for fast turn around and minimal post flight maintenance. Now let's move on to flights 13 through 15.
They're expected to showcase full reusability with recovery of both the booster in the ship via the Meccazilla catching system. That goal depends on the flight history of Block 3 hardware, of course. Engineers are testing new metallic heat shield tiles with embedded coiling channels that use methane to absorb heat during reentry, and these active tiles are designed for fast inspection and replacement, supporting A cadence near weekly launches once reliability is proven.
Star Base and Kennedy Space Center have already upgraded infrastructure to support up to 50 landings per year. This high frequency will shorten the learning cycle and create more consistent engineering feedback for SpaceX. It also reduces the time between major system upgrades, which will help SpaceX move faster towards stable operations. These upcoming flights will also test the hardware and software
needed for in orbit refueling. Specialized tanker versions of Starship will attempt cryogenic fuel transfer in orbital docking. The vehicles are receiving new insulation systems and revised plumbing designed to prevent boil off during long stays in orbit. Software for automated rendezvous and docking is being adapted from Crew Dragons flight code, both modifications for Starships larger size and higher volume fuel. NASA's Artemis lunar program depends on Starship's ability to
refuel an urban. Without that capability, Starship cannot deliver cargo to the moon or return after landing. The tests over the next few flights will determine whether this part of the system will be ready in time for a 2027 crude landing. Raptor 3 engines are a huge performance boost since the beginning of this program. These engines operate at 350 bar chamber pressure and exceed A thrust to weight ratio of 180.
They're designed to be refurbished in less than 30 days, which supports the kind of rapid reuse the SpaceX needs to compete with expandable rockets on cost and on volume. Now, engineers are also moving away from relying solely on ceramic heat shield tiles. The new designs use hexagonal patterns with stronger attachment brackets, backup a blade of layers beneath each tile, and active cooling in
critical zones. These changes reduce the risk of full system loss from a single tile detachment. And SpaceX wants Starship to reach operational status by 2026. They want to set it to Mars. That means refueling tests, successful catch landings, and high frequency reuse all need to happen in the next 5 flights.
So if Flight 11 goes well all the way through Flight 15, and they can validate every single one of those systems as 100% successful, SpaceX will have turned Starship from an experimental platform into a reusable spacecraft with real deep space potential. And they might just hit their mark of going to Mars by the end of 2026. Hey, thank you so much for listening today. I really do appreciate your support.
