Hi everybody, and welcome back to the Elon Musk podcast. Today we're going to be talking about the SpaceX Starship I FT-2 launch that'll be happening from Boca Chica Starbase, Texas. We'll discuss the meticulous preparations of SpaceX has undertaken, the implications of the FA A's ongoing review following Starship's first Test flight, and what we can expect from this highly anticipated second launch attempt. But before we jump into the heart of the matter, a quick
note. The Elon Musk Podcast is made possible by you, the listeners to the Elon Musk Investors Club. By joining the club at joinclubelon.com you help us keep the show on the air every single day. Now this Tuesday was a crucial day for SpaceX as a Starship rocket was stacked atop its super heavy booster in South Texas, marking the beginning of the final preparations for its
second launch. Now, this occasion led to SpaceX founder Elon Musk to post on X or Twitter that Starship is ready to launch, awaiting FAA license approval and the mention of the FAA. The Federal Aviation Administration is noteworthy. The agency is still engaged in reviewing documents and data from Spacex's first attempt to launch Starship in April of 2023. That initial flight concluded about 90 seconds after liftoff due to engine difficulties and other problems with the booster.
Now, as part of their ongoing evaluation, the FEA is looking into several aspects of this incident, such as the environmental impact at the launch site and the delayed activation of the Rockets flight termination system. And in response to these setbacks, SpaceX generated a quote mishap investigation report and submitted it to the FAA. The FAA in turn will highlight the corrective measures SpaceX must implement prior to its
second test flight. The objective is to ensure the safety of not only property but also humans and wildlife in the vicinity of the South Texas launch site, which is close to both wetlands and the Gulf of Mexico. Now when probed for an update on this regulatory scrutiny and FAA spokesperson suggested that additional information could be forthcoming. In fact, on Wednesday at 6:00 PM Eastern, the FAA issued a statement indicating the SpaceX Starship mishap investigation remains open.
We clarified that they won't authorize another Starship launch until SpaceX enacts the identified corrective actions and complies with all license modification prerequisites. Now, beyond the regulatory stuff, it's worth noting the SpaceX has been incredibly busy with preparations at the Starbase launch site. They've worked diligently to upgrade the ground systems in the rocket itself.
For the second launch attempt. In the first flight, the absence of a sound suppression system caused significant structural damage, notably sending fragments of concrete from the launchpad, scattering across the vicinity of the Starbase location. And in order to mitigate this issue, SpaceX has constructed and tested a new water deluge and flame deflector system located under the Starship
launch mount. Now, the SpaceX engineering team has also been occupied with enhancing the interstage area between the first stage rocket and the upper stage Starship vehicle, now referred to as a hot staging ring, and the aim is to enable the Starship upper stage engines to ignite even before the Super heavy first stage finishes its burn. Although this is an intricate operation, a successful execution could significantly boost the mass to orbit performance of this launch vehicle.
And in preparation for the upcoming test flight, SpaceX has carried out two hot fire tests of the Booster 9 rocket and also ran tests on the Starship upper stage Ship 25. And both sets of hardware have mainly passed these trials and the next test flight, unlike commercial missions, will not carry any payloads or people. And the objective is to test the performance of the 33 Raptor rocket engines in the booster along with stage separation and the ignition of Starship 6
engines. And should the flight proceed as planned, Starship will complete almost 3/4 of an orbit around Earth before making a splashdown in the Pacific Ocean north of Hawaiian Island of Kauai. Now while the exact flight path might still be under wraps pending FAA approval and other regulatory checks, the anticipated trajectory does give
us plenty to talk about. Starship, once launched, aims to achieve a series of milestones that not only demonstrate the feasibility of the technology, but also provide invaluable data for future, more complex missions. The first part of the flight involves the ignition of Super heavy 33 Raptor rocket engines. These engines are expected to generate a massive amount of thrust, propelling the vehicle
through Earth's atmosphere. It's crucial for all these engines to operate in synchronization, not just for liftoff but also as the vehicle ascends. The Super Heavy booster is the real workhorse here, designed to lift the entire rocket assembly until it reaches a designated altitude where stage separation occurs. Now upon reaching this altitude, a highly crucial part of the
mission takes place. The stage separation is where the Super Heavy detaches from the Starship upper stage and at this point the upper stage, which has its own set of 6 Raptor engines, ignites to continue the journey into space. Now this stage aims to carry Starship almost 3/4 of an orbit around Earth is a complex dance, the physics and engineering requiring precise timing and flawless execution from both hardware and software systems on board.
And one of the most innovative features expected to be tested is the hot staging ring, designed to facilitate the seamless transition between the Super heavy booster and the Starship upper stage. And the hot staging ring would theoretically enable the upper stage engines to ignite even before super heavy has completed its burn and separated.
This complicated maneuver of successfully executed would revolutionize the mass to orbit performance metrics, allowing heavier payloads to be carried to space with greater efficiency. And after completing nearly 75% of US orbit, the plan is for Starship to descend into the Pacific Ocean north of the Hawaiian island of Kauai. This segment of the mission is equally critical because it involves reentry into the atmosphere which subjects the spacecraft to extreme temperatures and stresses.
A Starships heat shield and other protective measures will be put to the test here, essentially proving whether the vehicle is capable of enduring the harsh conditions it would face in an actual mission beyond Earth to orbit. Now let's talk about a Super Heavy booster. After separation, the design philosophy behind Super Heavy
focuses on reusability. Post separation, Super Heavy will execute a controlled descent burn back to Earth in The booster aims to land vertically as a designated platform, a maneuver that SpaceX has perfected with its Falcon 9 rockets. And achieving this with a Super Heavy booster would be another monumental milestone considering its enormous size and complexity. The booster is about 250 feet tall now.
By studying each segment of the flight path in extreme detail, SpaceX aims to gather a treasure trove of data that would inform future missions, be a lunar landings, Marcus Expeditions, or even more ambitious yet to be announced adventures into the
cosmos. And every piece of information, from engine performance and stage separation to reentry dynamics and splashdown is a puzzle piece in the grand scheme of the Starship.
