Boeing Starliner astronauts ‘are not stranded’ in orbit, NASA insists
NASA has insisted that its two Starliner astronauts are not stranded in orbit as it continues to investigate issues with the thrusters on the spacecraft. which is currently docked at the International Space Station (ISS).
The Starliner brought NASA astronauts Suni Williams and Butch Wilmore to the ISS on June 6 in what was the first crewed trip for the vehicle. But on the final approach to the orbital outpost, it became apparent that five of the Starliner’s thrusters were not functioning in the correct way.
The thrusters serve to maintain the appropriate orientation of the crew capsule and will be vital for guiding the Starliner toward its reentry into Earth’s atmosphere when the vehicle finally returns home. The agency has also been investigating five helium leaks that occurred on the Starliner during its journey to the ISS.
In a media conference streamed online on Friday, Steve Stich, manager of NASA’s Commercial Crew Program, said: “I want to make it very clear that Butch and Suni are not stranded in space.”
Stich said the plan is to bring the two astronauts back to Earth on the Starliner and that there was no rush to get the pair home.
The original mission would’ve seen Williams and Wilmore spend about a week aboard the station, but their time in orbit is now approaching the four-week mark with no target date announced for their return.
In a worst-case scenario, if engineers deem the condition of the Starliner too risky for the astronauts to travel in, it’s possible Williams and Wilmore could hitch a ride home on a docked Crew Dragon spacecraft operated by SpaceX. Alternatively, they could wait for a SpaceX Crew Dragon to be prepped and sent for them in a similar way to how a NASA astronaut Frank Rubio and two cosmonauts waited for a Russian Soyuz spacecraft after the one they traveled in suffered damage while docked at the station.
An international research project has discovered three extinct walnut species in the Canadian Arctic.
Two University of Saskatchewan scientists were part of the team that found the mummified walnut remains in an area covered by rainforest 45 million years ago. The walnuts were identified by using CT technology.
Dr. James Basinger is a professor emeritus of geological sciences at the University of Saskatchewan. He says the remains were still rooted in the soil —more than 3,000 kilometres away from the closest living tree.

Gino Pursina, a third year marketing student in the Faculty of Business and Economics, was part of the winning team at North Forge’s Ramp Up Weekend, securing a prize of $10,000. Pursina was the only UWinnipeg student who participated in this event. He intends to invest his share of the funds “into my business idea to help foster its growth and development.”
As North Forge describes it, Ramp Up Weekend pulls together developers, designers, makers, and entrepreneurs to build a minimum viable product from a new idea in 50+ hours, with the opportunity to pitch the product to win $10,000. The event is about building deeper connections among the start-up community – learning and taking the first steps toward entrepreneurship in Manitoba.
Pursina was up to the challenge. “A goal of mine this year was to push myself to take on tough challenges. When I caught wind of North Forge’s Ramp Up Weekend and its intense competition, I knew I couldn’t pass up the chance to compete.”
His team’s product focused on helping communication between med-tech companies and patients and physicians. He drew heavily upon his classroom experience, creating sample pro forma and cash flow statements, preparing effective slide deck presentations, understanding financial feasibility, and, from his entrepreneurship class, how to tell and sell a really good story.
Pursina recommends competing in Ramp Up Weekend to his fellow Faculty of Business and Economics students. The competition not only sharpens critical thinking skills in the pursuit of generating viable business ideas, it also sharpens soft skills such as working with people with different expertise.
“Being part of the winning team was exhilarating,” said Pursina. “Entering this competition supplied me with an invaluable set of experiences, but it also gave me the opportunity to showcase my skills in front of many looking for new talent, ideas, and students with drive. Through Ramp Up I learned that as long as there is value being added, there will always be people eager to listen and provide opportunities no matter how strange the business idea may be.”
