WASHINGTON: A pair of US astronauts stuck waiting to leave the International Space Station said Wednesday they were confident that the problem-plagued Boeing Starliner they rode up on would soon bring them home, even as significant uncertainties remain.
Butch Wilmore and Suni Williams blasted off on June 5 aboard the brand new spaceship that NASA is hoping to certify to ferry crews to-and-from the orbital outpost.
They docked the following day for what was meant to be roughly a week-long stay, but their return was pushed back because of thruster malfunctions and helium leaks that came to light during the journey.
No date has been set for the return, but NASA officials said Wednesday they were eying “late July.”
Asked during a live press call from the station whether they still had faith in the Starliner team and the spaceship, mission commander Wilmore replied: “We’re absolutely confident.”
“I have a real good feeling in my heart that the spacecraft will bring us home, no problem,” added Williams.
She said they were continuing to enjoy their time aboard the ISS, performing tasks like changing out the pump on a machine that processes urine back into drinking water, and carrying out science experiments such as gene sequencing in the microgravity environment.
They have also tested Starliner as a “safe haven” vehicle in case of problems aboard the ISS, and checked out how its life support performs when four people are inside.
Before Wilmore and Williams can come home, however, engineering teams need to run more simulations of similar thrusters and helium seals on the ground, to better understand the root causes of some of the technical issues Starliner experienced — and modify the way it will fly down, if necessary.
It was known there was one helium leak affecting the spaceship before the launch, but more leaks emerged during the flight. Helium, while non-combustible, provides pressure to the propulsion system.
What’s more, some of Starliner’s thrusters that provide fine maneuvering initially failed to kick in during its approach to the station, delaying docking.
Engineers are not sure why the craft’s computer “deselected” these thrusters, though they were able to restart all but one of them.
In a subsequent press call, Boeing executive Mark Nappi told reporters that the “working theory” for the thruster malfunction was overheating due to excessive firing.
Theories on the cause of the helium leaks ranged from debris entering the propulsion system to Boeing possibly installing seals that were undersized for the task.
NASA and Boeing insist Starliner could fly home in case of an emergency, particularly since the problems affected only certain thrusters that control orientation.
They have no concerns over any of the more powerful thrusters responsible for the “deorbit burn” that will bring the spaceship back.
But much remains unclear — including whether the orientation control thrusters that malfunctioned have become degraded, which would make it necessary to rely on other thrusters during descent, NASA official Steve Stich said.
He insisted that NASA wasn’t yet considering bringing Williams and Wilmore back on a SpaceX Crew Dragon, in what would amount to a major humiliation for the aerospace giant Boeing, whose reputation has taken a hit in recent years over the safety crisis affecting its commercial jets.
“The prime option today is to return Butch and Suni on Starliner,” said Stich, while conceding that a return flight on a SpaceX spaceship can’t be ruled out.
In 2014, both SpaceX and Boeing were awarded multibillion-dollar contracts by NASA to develop crewed spaceships after the retirement of the Space Shuttle program. SpaceX carried out a successful crewed test in 2020 and has flown dozens of people since.

Iran, European powers to hold nuclear talks in Turkiye
The Istanbul meeting follows Foreign Minister Abbas Araghchi's warning of "irreversible" consequences if the European powers move to reimpose United Nations sanctions on Iran that were lifted under a 2015 deal.
The so-called E3 were parties to that agreement along with China, Russia and the United States.
But Trump effectively torpedoed the deal during his first term in 2018, by unilaterally abandoning it and reimposing sanctions on Iran's banking sector and oil exports.
A year later, Iran responded by rolling back its own commitments under the deal, which provided relief from sanctions in return for UN-monitored restrictions on Iran's nuclear activities.
The three European powers have been weighing whether to trigger the 2015 deal's "snapback" mechanism, which would reinstate UN sanctions in response to Iranian non-compliance -- an option that expires in October.
Such a stance "risks provoking a global nuclear proliferation crisis that would primarily affect Europeans themselves, Iran's top diplomat warned.
However, writing in the French weekly Le Point, he also noted that Tehran was "ready to turn the page" in its relations with Europe.
Friday's meeting with the European powers comes less than a week after a fourth round of Iran-US nuclear talks which Tehran called "difficult but useful", and after which a US official said Washington was "encouraged".
Araghchi said Friday's talks will be at deputy foreign ministers level.
Ahead of the talks, China, which held recent talks with Iran on its nuclear programme, said it remained "committed to promoting a political and diplomatic settlement of the Iran issue."
It also "valued Iran's commitment to not develop nuclear weapons, respected Iran's peaceful use of nuclear energy and opposed all illegal unilateral sanctions," according to Chinese foreign ministry spokesman Lin Jian.
Speaking on a visit to Qatar Thursday, Trump said the United States was "getting close" to a deal with Iran that would avert military action.
"We're not going to be making any nuclear dust in Iran," he said.
The Oman-mediated Iran-US talks were the highest-level contact between the two foes since Washington abandoned the nuclear accord in 2018.
Since returning to office, Trump has revived his "maximum pressure" policy on Tehran, backing nuclear diplomacy but warning of military action if it fails.
On Thursday, US news website Axios reported that the Trump administration had given Iran a "written proposal" for a deal during the fourth round of talks on Sunday.
Araghchi denied the report, saying "we have not been given anything".
He added however that "we are ready to build trust and transparency about our nuclear programme in response to the lifting of sanctions."
Trump has said he presented Iran's leadership with an "olive branch", adding that it was an offer that would not last for ever.
He further threatened to impose "massive maximum pressure", including driving Iranian oil exports to zero if talks failed.
Iran currently enriches uranium to 60 percent, far above the 3.67 percent limit set in the 2015 deal but below the 90 percent needed for a nuclear warhead.
Tehran insists its right to continue enriching uranium for peaceful purposes is "non-negotiable" but says it would be open to temporary restrictions on how much uranium it enriches and to what level.
On Wednesday, Iran's atomic energy agency chief Mohammad Eslami reiterated that Tehran "does not seek nuclear militarisation", adding that enrichment was under the supervision of the UN nuclear watchdog.
"The dismantling of enrichment is not accepted by Iran," he stressed.
EU chief vows to 'increase pressure' until Putin ready for peace
TIRANA: EU chief Ursula von der Leyen vowed Europe would "increase the pressure" until Russia's Vladimir Putin is ready for peace, as the first talks in three years between Moscow and Kyiv got underway in Turkey.
"We will increase the pressure," von der Leyen told reporters at a gathering of European leaders in Tirana, saying work was underway on a new package of sanctions. "We want peace and we have to increase the pressure until President Putin is ready for it," she said.
Putin made ‘mistake’ sending ‘low-level’ team to Ukraine talks: NATO chief
TIRANA: NATO chief Mark Rutte said Vladimir Putin had made a “big mistake” sending a lower-rank Russian delegation to conduct Friday’s first direct peace talks with Ukraine in three years.
“He knows extremely well that the ball is in his court, that he is in trouble, that he made a big mistake by sending this low-level delegation,” Rutte told reporters at a gathering of European leaders in Tirana. “He has to be serious about wanting peace. So I think all the pressure is now on Putin.”
Rubio meets top Turkiye, Ukraine officials ahead of war talks
ISTANBUL: US Secretary of State Marco Rubio was meeting with top Turkish and Ukrainian officials in Istanbul Friday, ahead of the first direct Russia-Ukraine talks in three years, officials on both sides said.
Rubio had on Thursday played down hope of progress at the meeting, saying "we don't have high expectations," but has nonetheless flown in to throw his weight behind the effort.
After landing in Turkey's largest city, Rubio went straight into talks at Dolmabahce Palace with his Turkish and Ukrainian counterparts, Hakan Fidan and Andriy Sybiga, respectively.
Also present at the meeting were Washington's envoy to Turkiye Tom Barrack and the US envoy for Ukraine Keith Kellogg as well as Ukraine's presidential chief of staff Andriy Yermak and Defence Minister Rustem Umerov, a Turkish foreign ministry source said.
Official photos from the meeting showed that Turkiye's spy chief Ibrahim Kalin was also present as was its former Moscow envoy, Mehmet Samsar.
Rubio himself was not expected to join the peace talks.
A source at Turkiye's foreign ministry had initially said the Russia-Ukraine talks would begin at 0930 GMT, although other officials said the exact timings appeared to be in flux.
Also ahead of the talks, Michael Anton, the State Department head of policy planning, was to hold a meeting with the Russian delegation at Dolmabahce, State Department spokesperson Tammy Bruce said.
Zelensky sent a pared-down team to the Istanbul talks after Russia showed up with a relatively low-level delegation.
Neither Sybiga nor Yermak are part of the Ukrainian delegation to the talks, which will be led by Defence Minister Rustem Umerov.
The Russian side is headed by Vladimir Medinsky, a hawkish adviser to Putin who has questioned Ukraine's right to exist and led failed talks at the start of the war.
Polio outbreak declared in Papua New Guinea
SYDNEY: A polio outbreak has been declared in Papua New Guinea, sparking concern about the disease's spread in a country with low vaccination rates, health officials said.
Poliovirus, most often spread through sewage and contaminated water, is highly infectious and potentially fatal.
It can cause deformities and paralysis and mainly affects children under five years old.
The virus was detected in wastewater and environmental samples in the Pacific nation's capital Port Moresby and second largest city Lae, the World Health Organization (WHO) said.
In subsequent testing, two children in Lae were found to have the poliovirus type 2 strain, according to the WHO representative in Papua New Guinea, Sevil Huseynova.
The confirmation of community transmission in the children "constitutes a polio outbreak", Huseynova said in briefing notes provided to AFP on Friday.
The health agency "expresses deep concern over the confirmed outbreak", she said.
Genetic testing showed the polio strain detected in Papua New Guinea was linked to one circulating in Indonesia.
Papua New Guinea was certified as polio-free in 2000, but immunisation rates among children are low -- less than 50 percent, according to the WHO.
"Polio is a highly infectious disease, and in communities with low polio immunisation rates, the virus quickly spreads from one person to another," Huseynova said.
Papua New Guinea Health Minister Elias Kapavore said the situation was "serious but manageable".
"We've dealt with this before and know what works," he told reporters on Thursday.
"Vaccination is safe and effective, and we're acting quickly to keep children protected."
