SpaceX Successfully Launches Sixth Starship Without Booster Recovery

On November 19, SpaceX successfully launched its Starship vehicle on the sixth test flight. However, unlike previous launches, the company did not recover the Super Heavy booster. Instead, the booster performed an offshore divert and landed in the Gulf of Mexico, ultimately tipping over and exploding. Despite this, the mission was still considered a success as Starship was placed on a suborbital trajectory, tested key engine capabilities, and made a successful reentry, though with minor damage to its thermal protection system. SpaceX also plans to incorporate improvements in future launches, particularly in the areas of vehicle design and recovery systems.

Summary

  • Launch Details: SpaceX launched Starship’s sixth test flight from Starbase, Boca Chica, Texas, on November 19.
  • Launch Window: The liftoff took place at 5:00 PM Eastern, with no reported issues during the countdown.
  • Booster’s Failure: The Super Heavy booster (Booster 13) was initially intended for recovery at the launch site but was diverted offshore after about three minutes.
  • Booster’s Final Fate: The booster landed in the Gulf of Mexico and exploded shortly after tipping over.
  • Starship’s Success: Despite the setback with the booster, the Starship upper stage successfully reached suborbital trajectory.
  • Reentry Testing: The Starship performed a reentry over the Indian Ocean, with the company purposefully stressing its systems to evaluate the vehicle’s limits.
  • Flap Damage: Starship sustained minor damage to its flap and thermal protection systems.
  • Splashdown: The vehicle made a powered soft landing in the ocean and was seen floating on its side in daylight, allowing for better video coverage.
  • Future Upgrades: SpaceX plans to stretch the Starship for larger propellant tanks and improve its thermal protection systems for future missions.
  • Flight License: SpaceX was able to conduct this test flight just over a month after the previous one without needing modifications to its Federal Aviation Administration (FAA) license.

Introduction

SpaceX’s Starship program continues to push boundaries with its ambitious goals for space exploration. On November 19, SpaceX launched the sixth test flight of its Starship/Super Heavy vehicle, marking a significant moment in the development of the next-generation spacecraft. However, this launch was not without its challenges. While Starship’s upper stage achieved its mission objectives, the Super Heavy booster was not recovered as planned, ending the mission with a setback. Despite this, SpaceX’s ability to test key systems and collect valuable data for future launches proves that the company is making significant strides in its quest to create a reusable, fully integrated spacecraft for missions to the Moon, Mars, and beyond.

SpaceX’s Starship/Super Heavy vehicle, also known as Starship, took off from SpaceX’s Starbase test site in Boca Chica, Texas. The launch occurred at the opening of a 30-minute window at 5:00 p.m. Eastern, and everything went smoothly during the countdown. Among those in attendance was President-elect Donald Trump, who has maintained a close relationship with SpaceX CEO Elon Musk. The event was a significant milestone for SpaceX, not just because of the launch itself, but also due to the high-profile nature of the occasion.

SpaceX Successfully Launches Sixth Starship Without Booster Recovery

Following a successful liftoff, the Super Heavy booster, designated Booster 13, separated from the Starship upper stage approximately 2 minutes and 45 seconds after launch. The booster then began its return to the launch site, where SpaceX had planned for it to land. However, just over a minute later, SpaceX engineers announced a “booster offshore divert,” indicating that the booster would not be returning to the launch pad. Instead, the booster made a powered landing in the Gulf of Mexico, just offshore of the launch site. Moments later, the booster tipped over and exploded.

This marked a minor setback for SpaceX, especially following the success of the previous flight on October 13, when the company was able to successfully “catch” the Super Heavy booster back at the launch tower. Despite the booster’s failure to land as planned, the mission was still considered a success due to the Starship upper stage’s ability to complete its objectives.

While the Super Heavy booster failed to land, the Starship upper stage (Ship 31) successfully reached a suborbital trajectory. This achievement was a critical step in SpaceX’s testing program, as it demonstrated that Starship’s propulsion system and overall design were capable of reaching the necessary velocity to enter space. During the flight, SpaceX engineers also performed a test by reigniting one of Starship’s Raptor engines, a critical maneuver for deorbit burns on future missions.

Before the launch, SpaceX had announced that it would be intentionally stressing the limits of the vehicle during the reentry phase. This was done to test the vehicle’s systems and understand how much they could handle in extreme conditions. SpaceX’s Kate Tice, one of the hosts of the webcast, stated, “Do not be surprised if this is not a smooth flight to splashdown today. We are intentionally looking for how far we can push and discover the vehicle’s true limits as we plan for future ship return and catch.”

Starship performed reentry over the Indian Ocean, with the vehicle experiencing some damage to a flap and other parts of the thermal protection system. SpaceX had specifically used an older version of the thermal protection system than the one used in previous flights, another test of the spacecraft’s durability. Despite the damage, Starship survived the reentry and ultimately made a soft landing in the ocean. The successful splashdown took place 65 and a half minutes after liftoff, with the vehicle floating on its side in the daylight hours, allowing for better video coverage of the return.

SpaceX Successfully Launches Sixth Starship Without Booster Recovery

SpaceX is already planning upgrades to the Starship system for future flights. The company plans to stretch the upper stage of the vehicle to accommodate larger propellant tanks, which will allow for more fuel to be carried on future missions. This will increase Starship’s payload capacity from 1,200 tons to 1,500 tons. Additionally, the design of the vehicle’s forward flaps, used for controlling the vehicle during reentry, will be adjusted. These new flaps will be smaller and placed in a different location to provide better protection against the heat of reentry.

One of the significant upgrades in future flights will involve improving the vehicle’s thermal protection system. SpaceX intends to make modifications to Starship’s heat shields and thermal protection tiles, addressing some of the issues observed during this flight. The company is working toward making the system more robust, ensuring that Starship can handle the extreme heat of reentry during deep-space missions, such as those planned for the Moon and Mars.

FAA Launch License

SpaceX was able to launch this test flight just over a month after the previous one because it did not need to modify its Federal Aviation Administration (FAA) license. The license issued by the FAA for the fifth flight also covered this mission. The limited changes to the vehicle for the sixth test flight were deemed to be within the scope of what had already been analyzed and approved by the FAA.

Facts

  • SpaceX’s goal is to develop Starship as the most powerful rocket in history, capable of carrying both crewed and uncrewed missions to Mars.
  • The Super Heavy booster, which is designed to provide the necessary thrust for Starship’s missions, is powered by Raptor engines.
  • The name “Starship” refers not just to the upper stage of the vehicle but to the entire system, which includes the Super Heavy booster and the upper stage.

Elon Musk Says FAA Should Make Boeing Pay for Putting Starliner Astronauts at Risk, Not Fine SpaceX

Elon Musk Says FAA Should Make Boeing Pay for Putting Starliner Astronauts at Risk, Not Fine SpaceX

Elon Musk recently criticized the Federal Aviation Administration (FAA) for proposing fines against SpaceX instead of focusing on safety issues with Boeing’s Starliner. Musk emphasized that Boeing’s Starliner spacecraft had put astronauts at risk, yet the FAA was fining SpaceX over what he called “trivial” violations. Musk called on the FAA to redirect its focus and hold Boeing accountable for safety failures.

Summary

  • Elon Musk publicly criticized the FAA for fining SpaceX over minor infractions while ignoring safety concerns with Boeing’s Starliner.
  • The FAA proposed a $633,009 fine against SpaceX for violating launch licenses during two launches in 2023.
  • SpaceX used an unapproved launch control room and rocket propellant farm during those missions.
  • Musk accused the FAA of focusing on “petty matters” that didn’t involve safety, while Boeing’s Starliner program jeopardized astronaut safety.
  • Boeing’s Starliner spacecraft has faced multiple safety issues, including thruster malfunctions and helium leaks.
  • Musk highlighted that NASA had turned to SpaceX’s Crew Dragon for astronaut returns due to concerns with Boeing’s Starliner.
  • Despite Boeing’s issues, the FAA has yet to fine the company, which Musk sees as a clear double standard.
  • SpaceX has completed multiple successful missions, including the Polaris Dawn mission and the world’s first commercial spacewalk.
  • Musk and SpaceX have had ongoing disputes with the FAA over delays, safety concerns, and environmental regulations.
  • Musk suggests that the FAA’s actions may be influenced by external pressure and not genuine safety concerns.

Elon Musk’s Response to FAA Fines

On September 6, 2023, the FAA proposed a $633,009 fine against SpaceX for violations related to launch licenses. These violations occurred during two separate launches in 2023. The FAA accused SpaceX of using an unapproved launch control room and an unapproved rocket propellant farm during these missions.

In response, Elon Musk expressed his frustration with the FAA’s decision. In a post on X, Musk accused the FAA of focusing on “petty matters” and ignoring real safety concerns with Boeing’s Starliner program. He tweeted, “NASA deemed the Boeing capsule unsafe for astronaut return, turning, out of necessity, to SpaceX, yet instead of fining Boeing for putting astronauts at risk, the FAA is fining SpaceX for trivia!”

Musk’s frustration stems from what he sees as a clear double standard. While SpaceX is being penalized for minor infractions, Boeing’s Starliner spacecraft has faced significant safety concerns, including thruster malfunctions and helium leaks.

For more details on the FAA’s fine, check out their official announcement on their website here.

The Boeing Starliner spacecraft has faced numerous technical issues, most notably during its mission in June 2023. After docking with the International Space Station (ISS), the spacecraft experienced thruster issues and helium leaks, which delayed the return of astronauts Butch Wilmore and Suni Williams. As a result, NASA opted to use SpaceX’s Crew Dragon for future astronaut returns, citing safety concerns with the Starliner.

Boeing has faced scrutiny over its ability to deliver a safe spacecraft, and yet the FAA has not issued fines against the company. Musk’s frustration is partly due to the fact that Boeing, despite its safety issues, has escaped financial penalties.

For more on Boeing’s Starliner challenges, see thisSpaceX update.

Elon Musk Says FAA Should Make Boeing Pay for Putting Starliner Astronauts at Risk, Not Fine SpaceX

Musk’s History of Disputes with the FAA

This isn’t the first time Musk has had issues with the FAA. SpaceX recently criticized the FAA for delaying the launch of its Starship vehicle, pushing the mission from mid-September to late November. In a statement, SpaceX accused the FAA of unnecessary delays, stating that the delay was “driven by superfluous environmental analysis” rather than actual safety concerns.

SpaceX also said the delays were based on “false and misleading reporting” by online detractors and special interest groups. Musk has often voiced his concerns over what he sees as bureaucratic inefficiencies within the US government, even floating the idea of joining a potential Trump administration to lead a new Department Of Government Efficiency (DOGE) if the former president wins the next election. You can read more about Musk’s involvement with the government in this article.

For further updates on SpaceX’s progress, visit the officialSpaceX updates page.

Despite its ongoing disputes with the FAA, SpaceX continues to make groundbreaking strides in space exploration. In September 2023, SpaceX successfully completed the Polaris Dawn mission, which involved a crew of four non-astronauts. During this mission, the crew conducted the world’s first commercial spacewalk, further cementing SpaceX’s reputation as a pioneer in the commercial space sector.

Meanwhile, Boeing’s Starliner spacecraft has yet to prove itself as a reliable alternative. While it has completed a handful of missions, technical malfunctions and safety concerns continue to plague the spacecraft, delaying its progress in NASA’s Commercial Crew Program. Musk has pointed out that SpaceX’s Crew Dragon finished development “4 years sooner” than Starliner, as he noted in a May 2023 X post.

Musk’s criticism of the FAA is not solely about SpaceX. He argues that the regulatory body is not holding Boeing accountable for serious safety concerns. In fact, NASA itself has expressed concerns over Starliner’s readiness. NASA deemed the spacecraft unsafe for astronaut return, which is why astronauts Wilmore and Williams will return to Earth in February 2025 via SpaceX’s Crew Dragon.

Musk’s demand for fairness and accountability is at the heart of his rebuke of the FAA. He believes that Boeing should face penalties for its shortcomings, rather than SpaceX being fined for what he calls “trivial” matters. In a letter to top congressional leaders, SpaceX forcefully rejected the FAA’s accusations, stating that “these distractions continue to directly threaten national priorities and undercut American industry’s ability to innovate.” You can read more about this letter and Musk’s rebuke in this Business Insider article.

As the space race between SpaceX and Boeing continues, Musk’s latest comments highlight the broader debate over regulation and innovation. While SpaceX has repeatedly proven its ability to deliver successful missions, Boeing’s Starliner program still faces significant challenges.

Moving forward, it remains to be seen how the FAA will respond to Musk’s criticisms and whether Boeing will face further scrutiny. What is clear is that spaceX’s continued innovation, despite regulatory hurdles, has made it the dominant force in the commercial space industry.

Elon Musk’s call for accountability from the FAA shines a light on the broader issues of regulation and safety in the commercial space industry. While SpaceX continues to push the boundaries of space exploration, Boeing’s Starliner spacecraft has faced repeated setbacks and safety concerns. As the space race continues, the FAA must ensure that all companies, including Boeing, are held to the same safety standards.

  • Starship and Super Heavy rocket are the likely vehicles for Raptor 3, each utilizing multiple Raptor engines.
  • Future enhancements are planned, with potential gains in thrust and efficiency.
  • Two versions of the Raptor engine exist: Sea Level (for liftoff) and RVac (for vacuum operations).

Summary

  • SpaceX introduced Raptor 3, marking a significant upgrade from Raptor 1 and 2.
  • Thrust and specific impulse improvements show how much more powerful the Raptor 3 is.
  • The Starship spacecraft and Super Heavy rocket will likely house the Raptor 3 engine.
  • Sea Level and RVac models cater to different phases of space travel, each designed for maximum efficiency.
  • SpaceX’s CEO, Elon Musk, indicates future upgrades are underway, aiming for more thrust and mass reduction.
  • The Raptor 3 engine could see advancements, eventually increasing thrust beyond 300 tons and enhancing efficiency.

Introduction

Those who follow the exploits of SpaceX, the commercial space launch and exploration company, recently learned about the unveiling of their third-generation reusable methane-oxygen staged combustion engine—the Raptor 3. Known as a powerhouse, the Raptor engine provides much more thrust than SpaceX’s Merlin engine, which is used in Falcon 9 rockets. The Raptor 3 represents the culmination of improvements in thrust, weight, and efficiency over two previous versions. Both SpaceX and its founder, Elon Musk, have shared updates about this new model on X (formerly Twitter), giving us insights into the technical advancements and the company’s future ambitions.

Specifications Compared to Previous Versions

One of the key aspects of any new technological development is how it improves upon previous versions. For the Raptor 3 engine, SpaceX has released comparative data on its three most important metrics: thrust, specific impulse, and engine mass.

Version Thrust (tf) Specific Impulse (s) Engine Mass (kg)
Raptor 1 185 tf 350 s 2080 kg
Raptor 2 230 tf 347 s 1630 kg
Raptor 3 280 tf 350 s 1525 kg

Thrust is measured in ton-force units (tf), which shows how much force the engine can produce. The specific impulse (s) is a measure of how efficient the engine is in using fuel to generate thrust. Finally, the engine mass (kg) indicates how heavy the engine is.

  • Thrust Improvement: From Raptor 1’s 185 tf to Raptor 3’s 280 tf, the thrust has significantly increased, making the Raptor 3 far more powerful than its predecessors.
  • Specific Impulse: Interestingly, while Raptor 2 had a slight drop in specific impulse (347 s), Raptor 3 returns to 350 s, showing that it retains efficiency despite the increase in power.
  • Reduced Mass: Raptor 3 is also lighter than both previous versions, dropping from 2080 kg in Raptor 1 to 1525 kg in Raptor 3.

As Elon Musk noted on X, “We are constantly improving performance while reducing weight. Raptor 3 is our best work yet.” By reducing the mass and increasing thrust, SpaceX has built an engine that’s not only more powerful but more efficient in terms of fuel and material use.

Engine Design and Usage in Spacecraft

The Raptor 3 engine is designed with reusability and versatility in mind, making it ideal for multiple mission types, from launches from Earth to operations in space. While SpaceX hasn’t explicitly announced which spacecraft will use the Raptor 3, the Starship spacecraft and Super Heavy rocket are the most likely candidates.

The Starship System

The Starship system is SpaceX’s flagship project designed for deep space exploration. This system consists of:

  • Starship (the spacecraft) designed to transport crew and cargo to Earth orbit, the Moon, Mars, and beyond.
  • Super Heavy (the rocket) that powers Starship into space.

Elon Musk has frequently described Starship as the “world’s most powerful launch vehicle ever developed.” A fully reusable Starship will be capable of carrying up to 150 metric tons or 250 metric tons in an expendable configuration. At its core, both Starship and Super Heavy rely on Raptor engines for propulsion.

Raptor 3 in Starship

In terms of engine configuration:

  • The Starship spacecraft is powered by six Raptor engines:
    • Three Sea Level Raptors (optimized for liftoff and atmospheric escape).
    • Three RVac Raptors (optimized for vacuum space operations).
  • The Super Heavy rocket is powered by 33 Raptor engines.

This combination of engines ensures that Starship can navigate both atmospheric and space environments, making it a versatile option for multi-destination missions. The Raptor 3 will likely play a crucial role in both components of SpaceX’s interplanetary ambitions.

Sea Level vs. RVac Models

Sea Level Model

The Sea Level Raptor 3 is the model revealed so far. It’s designed for launch and atmospheric operations, providing the thrust needed to break free of Earth’s gravitational pull. These engines feature a smaller exhaust nozzle optimized for high-pressure environments near the surface of planets.

RVac Model

The RVac (Raptor Vacuum) engines, on the other hand, are designed for vacuum conditions in space. They come with a much larger exhaust nozzle for optimal performance outside Earth’s atmosphere. According to Musk, future versions of the RVac Raptor 3 could offer a specific impulse of up to 380 seconds. “In a few years, we will finally have a Raptor 3/4 vacuum version (giant nozzle) with ISP of 380,” Musk tweeted. This would mark a major leap in spacecraft efficiency, particularly for missions to distant planets like Mars.

Engine Type Primary Use Key Feature Specific Impulse (s)
Sea Level Raptor 3 Liftoff and atmospheric escape Smaller nozzle for high pressure 350 s
RVac Raptor 3 (Projected) Vacuum space travel Larger nozzle for vacuum efficiency 380 s (target)

Future Development and Potential Upgrades

SpaceX is not content with the current version of the Raptor 3. In fact, Musk has hinted at further improvements. He mentioned that engineers are working on increasing the thrust to over 300 tons, improving the thrust-to-weight ratio, and potentially gaining 5 seconds of specific impulse in future iterations.

This relentless focus on optimization could make future versions of Raptor 3 even more competitive in terms of payload capacity, reusability, and interplanetary missions. With SpaceX aiming to establish a sustainable presence on Mars, these advancements could be pivotal.

SpaceX Falcon 9 Rocket Launches Return Following FAA Green Light

SpaceX Falcon 9 Rocket Launches Return Following FAA Green Light

SpaceX’s Falcon 9 rockets have resumed launches after a temporary pause due to a failure on July 11. The Federal Aviation Administration (FAA) cleared SpaceX to return to flight operations on July 25, following corrective measures for the anomaly. The successful relaunch on July 26 marks a significant step forward, allowing SpaceX to continue its space missions with an improved focus on safety and reliability. Upcoming missions include both crewed and uncrewed flights, with high-profile projects like the Polaris Dawn mission and the Crew-9 mission scheduled in the near future.

Summary

  • FAA Green Light: SpaceX received approval from the FAA to resume Falcon 9 launches.
  • July 11 Failure: The anomaly was caused by a crack in a pressure sensor line, leading to an oxygen leak.
  • SpaceX’s Response: The company has removed the faulty sensor lines and implemented corrective actions.
  • Successful Launch: On July 26, SpaceX launched a Falcon 9 rocket carrying Starlink satellites.
  • Upcoming Missions: Includes Polaris Dawn, a private spacewalk mission, and the Crew-9 mission to the ISS.
  • Starship Tests: SpaceX is preparing for the fifth test flight of its Starship/Super Heavy system.
  • FAA Oversight: The FAA will continue to monitor SpaceX’s activities to ensure safety.

Introduction

SpaceX, the aerospace company founded by Elon Musk, has made headlines once again with the resumption of its Falcon 9 rocket launches. After a failed mission on July 11, which led to a temporary halt in operations, the company received a crucial green light from the Federal Aviation Administration (FAA) on July 25. This approval was a significant step in getting SpaceX back on track with its ambitious space exploration plans.

The July 11 Failure

On July 11, 2024, a Falcon 9 rocket experienced a significant failure that halted SpaceX’s flight schedule. The issue was traced to a crack in a pressure sensor line for the upper stage’s liquid-oxygen system. This crack caused an oxygen leak, which in turn led to degraded performance of the upper-stage engine. The failure resulted in the loss of 20 Starlink satellites that were intended to enhance SpaceX’s high-speed internet network.

The problem was identified as a fatigue crack in the sense line, which is crucial for monitoring the pressure of the liquid-oxygen system. According to SpaceX, the crack was caused by high loading from engine vibrations and a looseness in the clamp that normally holds the line in place. This malfunction led to excessive cooling of engine components during a planned coast phase, resulting in a hard start upon engine restart and damage to the hardware.

SpaceX took immediate action to address the issue. The company worked under FAA oversight to pinpoint the root cause and develop a corrective strategy. They removed the faulty sense lines and sensors from the upper stages of upcoming Falcon 9 rockets. As a result, the company could clear the way for the resumption of flights.

“The sensor is not used by the flight safety system and can be covered by alternate sensors already present on the engine,” SpaceX explained in a statement.

Resumption of Launches

Following the FAA’s green light, SpaceX quickly got back to its flight schedule. On July 26, 2024, the company successfully launched a Falcon 9 rocket from NASA’s Kennedy Space Center in Florida. The launch was notable for several reasons:

  • Timing: The rocket lifted off at 1:45 a.m. ET (05:45 GMT), demonstrating SpaceX’s ability to resume operations with minimal delay.
  • Mission Objective: Like the failed July 11 mission, this launch also carried a batch of SpaceX’s Starlink satellites to low Earth orbit.
  • Launch Success: The launch appeared to proceed without incident. The first-stage booster successfully landed on a drone ship in the Atlantic Ocean, while the second stage deployed 23 Starlink satellites into orbit.

The FAA’s evaluation of the July 11 failure concluded that there were no public safety issues involved. The agency’s determination allowed Falcon 9 rockets to return to flight operations while the overall investigation into the anomaly remained open. This decision reflects the FAA’s confidence in SpaceX’s ability to manage safety and address issues promptly.

Upcoming Missions and Future Prospects

SpaceX has several high-profile missions lined up, which include both crewed and uncrewed flights. These missions are critical for the company’s continued success and its role in advancing space exploration.

Polaris Dawn Mission

One of the upcoming missions is the Polaris Dawn mission, which is privately funded and led by billionaire entrepreneur Jared Isaacman. Scheduled for late summer, the Polaris Dawn mission will feature the first private-sector spacewalk. Isaacman has indicated that while there will be some additional training before launch, he remains confident in SpaceX’s capabilities:

“There are training currency requirements. We will likely have a few days of sim and EVA refreshers before launch. Most importantly, we have complete confidence in SpaceX and they have managed the 2nd stage anomaly and resolution. We will launch when ready and it won’t be long,” Isaacman said in a recent update.

Crew-9 Mission

Another significant mission involves delivering a quartet of astronauts, including both U.S. and Russian crew members, to the International Space Station (ISS). NASA’s Crew-9 mission is currently set for launch no earlier than August 18, 2024. NASA’s Commercial Crew Program Manager Steve Stich has emphasized the importance of transparency and safety:

“We’ve been following along, step by step with that investigation that the FAA has been doing. SpaceX has been very transparent.”

Uncrewed Dragon Cargo Capsule

Additionally, an uncrewed Dragon cargo capsule is scheduled for launch to the ISS no earlier than September 2024. This mission will continue to support the ISS with essential supplies and equipment.

Starship/Super Heavy Test Flights

spaceX is also making progress with its Starship/Super Heavy launch system, which is crucial for future deep space missions. The company has conducted successful static-fire tests of both the Super Heavy booster and the Starship second stage. The upcoming fifth test flight is anticipated to involve a new flight profile:

  • Booster Landing: Unlike previous missions where the booster splashed down in the Gulf of Mexico, the new plan involves having the booster land back at Starbase using two giant arms known as “chopsticks.”
  • FAA Licensing: This change in the flight profile may require a re-evaluation of SpaceX’s FAA license for Starship test flights.

Conclusion

SpaceX’s ability to resume Falcon 9 launches following the FAA’s green light is a testament to the company’s resilience and commitment to safety. The successful launch on July 26 and the planned upcoming missions reflect SpaceX’s ongoing efforts to advance space exploration and commercial spaceflight. With continued oversight from the FAA and rigorous testing of new technologies, SpaceX is poised to maintain its position as a leading player in the aerospace industry.
