NASA Astronauts' Return Delayed Due to Boeing Starliner Malfunction

In a significant setback, two NASA astronauts find themselves in an extended stay aboard the International Space Station (ISS) due to technical issues with Boeing’s Starliner spacecraft on its first crewed flight.

The return of the spacecraft has been postponed again after its scheduled re-entry to Earth faced delays. Initially set to return on June 26, the mission has now been pushed to an unspecified date in July. This decision follows an incident on June 6, when the Starliner docked at the ISS but encountered thruster malfunctions and helium leaks.

Astronauts Butch Wilmore and Sunita Williams, who were originally planned for a nine-day mission, now face an indefinite extension. Their return has been delayed twice this month, with no confirmed return date currently in sight.

The Starliner had a turbulent journey from the outset. Launched from Florida on June 5 atop a United Launch Alliance Atlas V rocket, the mission faced years of delays, safety concerns, and two aborted launches with astronauts ready on board.

NASA and Boeing issued a joint statement, explaining the latest delay was to provide more time for reviewing the propulsion system's data. This postponement also avoids conflicts with planned ISS spacewalks.

Steve Stich, manager of NASA’s Commercial Crew Program, reassured the public that the spacecraft is performing well. He refuted claims that the astronauts are “stranded,” emphasising that they could return to Earth if necessary.

Despite the delays, the astronauts are reportedly not in a hurry to depart, given the ISS is well-stocked with supplies, and the station’s schedule remains relatively open until mid-August.

“We are methodically following our mission management process,” said Stich. “Our decisions are data-driven, particularly concerning the small helium leaks and thruster performance observed during the docking process.”

The initial docking with the ISS was delayed by over an hour due to issues with Starliner’s thrusters, which are critical for fine manoeuvring.

Prior to launch, it was known that there was one helium leak. However, additional leaks were discovered during the flight.

This delay comes at a particularly challenging time for Boeing. The company is under intense scrutiny following two fatal crashes in 2018 and 2019, which have raised serious questions about the safety culture within its commercial aerospace division.
