Main Article

The Federal Aviation Administration (FAA) has grounded SpaceX’s Falcon rocket fleet for the third time in three months following a second-stage malfunction. This latest incident occurred during a high-profile mission that successfully transported two astronauts to the International Space Station (ISS) aboard a Dragon Crew capsule on Saturday. While the capsule reached its destination without issue, the rocket’s second stage suffered a failure less than 30 minutes after the astronauts were delivered into orbit.

This malfunction caused the FAA to halt additional SpaceX launches, including two major missions: the launch of OneWeb satellites and a Starlink satellite mission. The disruption could also impact critical upcoming solar system exploration missions from NASA and the European Space Agency (ESA), both of which have narrow launch windows scheduled for later this month.

The Second-Stage Failure

The Falcon 9’s Merlin Vacuum engine, designed to boost the rocket’s second stage into a higher orbit, failed to fire correctly. The second stage was tasked with executing a deorbit burn, a maneuver intended to guide the rocket safely back to Earth by burning up in the atmosphere. Without the proper deorbit burn, debris from the rocket could potentially fall outside of the designated area, leading to space debris concerns.

In a statement, SpaceX acknowledged the issue, stating:

Falcon 9’s second stage was disposed in the ocean as planned, but experienced an off-nominal deorbit burn. As a result, the second stage safely landed in the ocean, but outside of the targeted area.”

SpaceX has since been working on identifying the root cause of the malfunction. Although the issue was not catastrophic, the FAA requires a full investigation before launches can resume.

The failure of the deorbit burn raised concerns over space debris, often referred to as orbital space junk. Debris from failed rocket stages can pose significant risks to other spacecraft, satellites, and space stations in low Earth orbit. The FAA’s grounding of the Falcon rockets highlights the growing concern over maintaining safety in an increasingly crowded space environment.

This is not the first time SpaceX has faced issues with its rockets. Earlier this year, a Falcon 9 rocket suffered a second-stage explosion that sent several Starlink satellites on a destructive trajectory. Additionally, a Falcon 9 first stage made a crash landing on a drone ship after a different mission.

Impact on NASA and ESA Missions

The Hera mission, developed by the ESA to explore the Didymos binary asteroid system, and NASA’s Europa Clipper mission, which aims to study Jupiter’s moon Europa, are both at risk of delays. These missions have specific launch windows that must be adhered to in order to reach their destinations efficiently. Any delays could push back these high-priority exploration missions, costing both agencies valuable time and resources.

Mission	Agency	Launch Window	Destination
Hera Mission	ESA	October 7-27	Didymos Binary Asteroid System
Europa Clipper	NASA	October 10-30	Jupiter’s Moon Europa

The potential delay of these missions is particularly concerning for NASA’s Europa Clipper, a $5 billion project that seeks to unlock the mysteries of one of the solar system’s most intriguing moons. The Falcon Heavy rocket, which shares its second-stage design with Falcon 9, is slated to carry this mission.

SpaceX’s Response and Investigation

SpaceX has a track record of quick response times and thorough investigations following any malfunctions. In July, a previous second-stage failure led to a 15-day suspension of Falcon 9 flights. The company determined that the issue was a liquid oxygen leak, which was quickly resolved with modifications to the rocket’s design. Similarly, SpaceX is expected to rapidly identify and fix the current malfunction.

Despite these setbacks, Falcon 9 remains one of the most reliable rockets in the world, with a success rate of over 98% across more than 200 launches. However, the FAA’s involvement complicates the situation. SpaceX is currently embroiled in a legal dispute with the agency over delays in authorizing the fifth test flight of its Starship rocket at its South Texas facility. This dispute, combined with the current suspension, could result in further delays for SpaceX’s ambitious space exploration goals.

Rocket	Mission Success Rate	Notable Issues
Falcon 9	98%	Second-stage failures, first-stage landing mishaps
Falcon Heavy	100%	None

SpaceX’s Falcon Heavy is still scheduled to launch NASA’s Europa Clipper mission later this month, assuming the investigation wraps up in time. The company’s ability to learn from its mistakes and implement solutions swiftly will likely prevent further interruptions in its busy launch schedule.

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.
