 Nasa Stirling Nasa Starliner Launch, Inside Starliner Capsule

In order to resolve the problems, Boeing and its propulsion supplier, Aeroflot Rocketry, are proceeding with a number of modifications to the Star link spacecraft that conducted a test flight to the ISS last year, Steve Stich, manager of NASA's Commercial Crew Program, informed reporters Thursday. The modifications include thermal shunts and barriers to keep the spacecraft's thrusters from overheating, as well as new seals to stop helium leakage.

Boeing is still more than a year away from completing its multi billion-dollar NASA contract and beginning crewed flights to the ISS, while currently owing more than $2 billion for all Starlink delays. However, according to NASA sources, Boeing is dedicated to Starlink .

"Our ultimate objective is to get into crewed rotation flights with Starlink , and we're really working towards a flight with Starlink early next year," Stich stated. "And those won't begin until late next year, when the second crewed rotation slot is scheduled."

The spaceship will begin operational service for NASA in 2010, eleven years after Boeing officials launched the Starlink program.

The Tipping Point

It is likely that the upcoming Starlink voyage will not transport humans to the ISS, but merely cargo. However, NASA has not yet reached a definitive judgement. By 2027 or 2028, the agency has scheduled enough crewed rotation missions aboard SpaceX's Dragon spaceship to satisfy the station's requirements. 

"I would say that there are many benefits to flying a cargo flight first," Stich stated. "I believe Dragon benefited greatly from the early [cargo] flights before the crew contract was even signed for the space station, if we really look at the history of Starlink and Dragon."

The fact that a Starlink cargo mission would require one of the last Atlas V rockets from United Launch Alliance, which are now set aside for upcoming Starlink crew flights, is a disadvantage. In order to complete its whole contract with NASA, which includes six crewed trips, Boeing would then need to use another rocket.

 

Although Boeing claims that Starlink can launch on a number of different rockets, it is important to consider how challenging it would be to modify the spacecraft to fit a new launch vehicle, like ULA's Vulcan. Boeing and ULA had to solve an unforeseen aerodynamic load problem that was found during wind tunnel testing early in the Starlink development process. In response, engineers created a skirt—an aerodynamic extension—that would fit beneath the Starlink spaceship atop its Atlas V rocket.

From the beginning, Starlink has been beset by delays. The program was delayed by roughly two years due to NASA budget cuts in the early 2010s, but Boeing was mostly responsible for the remaining schedule slippages. A fuel leak and fire during a crucial ground test, parachute issues, redesigns to account for unforeseen aerodynamic forces, and a computer timing error that ended Starlink 's 2019 first attempt to reach the space station were among the setbacks.

All of this culminated last summer with the program's first astronaut test flight. The two crew members of the spacecraft stayed on the ISS until they could return home on the SpaceX Dragon spacecraft this year, however the mission concluded with the Starlink returning to Earth empty due to helium leaks and overheating thrusters.

Boeing was disappointed with the outcome. Boeing was on the verge of being one of NASA's approved crew transportation providers to the ISS and eventually making money before to last year's crewed test mission.

Regarding Starlink future, Boeing officials had been silent for months. At the conclusion of the Starlink test flight last September, a Boeing program manager abruptly left a NASA press conference, and the firm declined to comment on its long-term commitment to the program.

However, in recent months, that has changed. The company plans "more missions on Starliner," according to Kelly Ortberg, who took over as CEO of Boeing last year. She also told CNBC in April that the effort to fix the thruster issues the spacecraft encountered last year is "very straightforward."

Ortberg declared, "We're taking corrective action because we know what the issues were." "So, in the upcoming years, we hope to do a few more flights here."

Task and Objective 

Even as Starliner's only destination, the ISS, approaches its sunset years, NASA officials are still keen to start these frequent crewed orbital missions. Thirty years after the launch of the lab's first module, NASA and its foreign partners intend to decommission and destroy the space station in 2030 and 2031.

The agency's second commercial crew contractor, SpaceX, is not experiencing any performance problems, which is why NASA wants to put Starliner online. With its Dragon spacecraft, SpaceX has met or beyond all of NASA's requirements on 11 extended journeys to the ISS. SpaceX has developed a dependable rhythm with Dragon missions for NASA and other clients since its first crewed flight in 2020.

 

But there are some doubts regarding SpaceX's long-term ambitions for the Dragon program, and those doubts weren't unfounded when Elon Musk, the company's creator and CEO, stated on X last month that SpaceX would start ending the Dragon program "immediately." In a battle that has seen the former political allies plummet in the months of Trump's second term in office, Musk and President Donald Trump exchanged insults and threats on social media.

Musk quickly withdrew his warning to terminate the Dragon program in a subsequent post on X.penultimate month, SpaceX's fifth and penultimate human-rated Dragon capsule made its debut on its first trip to the International Space Station.

Bill Gerstenmaier, vice president of building and flight at SpaceX, stated, "I would say we are very committed to the space business." "We are dedicated to safely launching people into space."

Musk's threat to shut down Dragon has some merit. Musk has long desired to shift SpaceX's attention from the Dragon program to Starship, the company's next-generation big rocket. SpaceX envisions Starship as the ultimate Dragon and Falcon 9 rocket replacement.

Although there is no assurance that SpaceX will continue to fly Dragon into the 2030s, NASA expects that private space stations will be able to assume its ISS obligations once it retires. Plans for commercial space stations are rather dubious as a result.

In the 2030s, Starliner and Starship might be the only means of transporting humans to and from commercial space stations in low-Earth orbit. Later in this chapter, we'll talk about the reasoning behind that scenario.

The price of a ticket to low-Earth orbit on Starliner or Starship is less certain than the price of a seat on SpaceX's Dragon. Moreover, Starship is incompatible with certain commercial outposts because of its significantly larger size, which might be too much for the comparatively small space station to manage its own orientation. This issue has been noted by NASA for their Gateway mini-space station, which is scheduled to orbit the moon.

When SpaceX will discontinue Dragon is tough to predict. The same is true for Starliner and Boeing. However, NASA and other clients want to purchase further Dragon missions.

Dragon's days will be numbered if SpaceX can demonstrate that Starship is safe enough to launch and land with humans on board. However, Starship may not be human-rated for trips to and from Earth orbit for at least a few years. The spacecraft would need to be approved for both launch and landing on Earth in order to fulfil NASA's agreement with SpaceX to build a version of Starship that would land humans on the moon. The risks of re-entry into Earth's atmosphere, which Starship wouldn't have to face for a lunar landing, plus the ship's lack of a launch abort system make it a more challenging task than a lunar mission in some respects.

It is unclear when Starship will be prepared for crewed trips, but once it is operational, it is expected to carry a lot more people and cargo than the Falcon 9 and Dragon. Until then, it's Dragon or bust for SpaceX if it hopes to establish a functioning human spaceflight program.
