NASA has announced a further delay in the launch of its upcoming Crew-9 mission to the International Space Station (ISS). The mission, originally scheduled for August 18, will now take place no earlier than September 24. The space agency cited the need for "operational flexibility" as it continues to evaluate the readiness of Boeing's Starliner spacecraft. This adjustment will provide more time for mission managers to finalize return plans for NASA's Boeing Crew Flight Test currently docked at the ISS.

One of the factors contributing to the delay is a deconfliction of traffic at the space station, including a scheduled Soyuz launch in mid-September. However, the primary reason for the postponement is the ongoing assessment of Starliner's flightworthiness and the safety considerations surrounding the return of its two crew members, Butch Wilmore and Suni Williams.

During the initial eight-day mission, issues with Starliner's faulty thrusters were observed, prompting NASA and Boeing engineers to thoroughly evaluate the spacecraft's capabilities. An autonomous undocking option is being considered, but it requires updating Starliner's flight software, which currently lacks the necessary functionality. NASA estimates it will take about four weeks to implement and validate the software for autonomous return, should the decision be made to use the Crew Dragon spacecraft for the journey back to Earth.

While the recent NASA news release did not address the software update issue or clarify the number of astronauts launching on Crew-9, a news conference scheduled for Wednesday will provide an opportunity for reporters to seek answers regarding Starliner's ability to return to Earth without crew members on board.

The final decision on whether to bring Wilmore and Williams home via Starliner lies with NASA Administrator Bill Nelson, who expressed confidence in the decision-making process. "Yes, I do," Nelson affirmed when asked about his confidence in NASA's deliberations. "I especially have confidence since I have the final decision."

In addition to the delay and the Starliner assessment, NASA revealed that the Crew-9 mission will now launch from Space Launch Complex 40 at the Cape Canaveral Space Force Station in Florida. This choice will allow for the use of Launch Complex 39A at the nearby Kennedy Space Center for NASA's Europa Clipper mission, which is scheduled for an October launch using a Falcon Heavy rocket.

The upcoming news conference is anticipated to shed more light on the potential return plans for the Starliner crew and provide clarification on the preparations and decisions for the Crew-9 mission. As NASA continues its careful evaluation, the safety and successful completion of future space missions remain of paramount importance.
