This decision necessitated a reassignment of astronauts Butch Wilmore and Suni Williams, who were to return on the Starliner. The safest and most logical solution was to include them in the Crew-9 mission, thus prompting the removal of two original Crew-9 astronauts, Zena Cardman and Stephanie Wilson.

With the changes, Crew-9 will now be a half-empty flight with only two crew members: Nick Hague and Aleksandr Gorbunov. Hague, who was originally the pilot of the mission, has been promoted to commander, while Gorbunov will remain as the mission specialist.

Nick Hague, a U.S. Space Force commander and former test pilot, has had an illustrious career in space exploration. He has already been to space twice as a NASA astronaut, although his first trip was cut short due to a rocket malfunction during a Soyuz launch in 2018. Despite this setback, Hague and his cosmonaut colleague Alexey Ovchinin safely returned to Earth, and both successfully completed a full ISS mission on their second attempt in 2019.

Aleksandr Gorbunov, on the other hand, will be making his first spaceflight on the Crew-9 mission. His seat is part of a NASA arrangement with Roscosmos, ensuring the continued presence of Russian astronauts on NASA missions, and vice versa. This collaboration is crucial for maintaining international relations and ensuring the success of joint space endeavors.

The decision to reassign astronauts has led to a delay in the Crew-9 launch, which is now scheduled for September 24, 2024. However, this date remains tentative due to complications arising from a separate incident involving SpaceX’s Falcon 9 rocket.

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.

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.
