This planetary geologist has worked on nearly every Mars rover while connecting government, universities, the private sector, and the public.

When NASA deployed a small six-wheeled robot named Sojourner on Mars in 1997, space-obsessed 11-year-old Tanya Harrison was watching.

“When NASA released the little animated GIF of Sojourner driving onto the surface, I thought, ‘I want to work on Mars rovers,’” she said. “I was laser focused on that goal from there out.”

When Canadian and European Space Agency leaders reaffirmed their commitment to work together in June, leaders focused their public remarks primarily on shared exploration goals and decades of fruitful partnership.

“Canada and the European Space Agency are working on a number of projects all the way from exploration to Earth observation, communication, navigation and many other domains,” ESA Director General Josef Aschbacher said in an interview with Canada’s CTV News. “This cooperation has to be deepened because it is absolutely fruitful for both sides.”

But Aschbacher also mentioned another critical component to the relationship. He noted the importance of Europe, Canada and other countries working together at a time when “the United States is focusing much more on the domestic activities and therefore international cooperation being maybe not of the highest priority, at least in space.”

Aschbacher is right about changing U.S. space priorities.

After decades of working closely with international space agencies, the Trump administration is reevaluating programs through an “America First” lens, which prioritize domestic prosperity over foreign-policy considerations. Through that lens, policymakers would consider whether a joint space program created U.S. jobs, improved the U.S. balance of trade with another nation or offered access to unique technology.

US President Donald Trump last week laid out one of the biggest challenges ever for NASA — to land the first humans on Mars.

But his detailed budget request for the fiscal year 2026 also proposed cancelling dozens of the space agency’s missions, including projects to study Earth, Mars and Venus. And the next day, on 31 May, Trump withdrew his nomination for NASA chief, the businessman and commercial astronaut Jared Isaacman.

All of this has left the space agency in turmoil, and the scientists who normally participate in NASA’s missions split over whether they support the push for the red planet.

Dr. Tanya Harrison, 39, was a planetary scientist working a high-profile job in the space industry when she decided to make a major life change. Between experiencing harassment on the job and working 12-hour days with no time for anything else, she realized it was time to try another path.

In 2023, Dr. Harrison left her job and moved back to her hometown of Seattle, and eventually Ottawa. This pivotal decision sparked a journey of self-discovery, during which she reconnected with her love for film photography and creative expression.

In this series, Reimagining Wealth, we explore the evolving definition of wealth in today’s world. Here, we talk to Dr. Harrison, now a consultant, author and science communicator, about her career shift and her journey to greater personal fulfilment.

Pop star Katy Perry and five other women safely returned to Earth after reaching space aboard Jeff Bezos’s Blue Origin rocket.

The singer was joined by Bezos’s fiancée Lauren Sánchez and CBS presenter Gayle King, who said a highlight of the flight was hearing Perry sing Louis Armstrong’s “What a Wonderful World”.

After landing back on Earth, Perry said she felt “super connected to life” and “so connected to love”.

The flight lasted around 11 minutes and took the six women more than 100km (62 miles) above Earth, crossing the internationally recognised boundary of space and giving them a few moments of weightlessness.

[…]

Dr Tanya Harrison, from the Outer Space Institute experts network said: “A lot of the comments that I saw on social media were things about, ‘Oh, it’s like the Real Housewives go to Mars’ or ‘It’s the oligarchy in space, read the room, the timing is terrible.'”

But: “There were a lot of positive takes as well. People were like, ‘Oh, this is so cool. Katy Perry is going to space.'”

Dr Harrison, who had previously worked on Nasa missions to Mars said: “The cynical part of me wants to call it a marketing stunt. This is a company promoting the fact they can launch tourists into space.”

However she noted the all-women team might “change the demographics a little bit of who might want to do something like this.”

Opening the newly published children’s book “Mia and the Martians,” readers see a young girl rushing to the edge of the page, proudly outstretching a pink rocket in her hand. The reader learns what the girl, Mia, is going to present for next week’s science fair.

“My favorite planet, of course! Mars!” exclaims the protagonist, Mia.

In her custom-built spaceship, Mia embarks on a fantastical journey to Mars with her co-pilot cat, Nebula. They meet the “Martians,” based on the real-life rovers of Mars throughout the story. Enlisting the rovers’ help, Mia learns the lesson of perseverance and finds a way back home to Earth. 

To bring this story to the page, astrophysicists Emma Louden GRD ’26 and Tanya Harrison partnered with Wouter Pasman, an illustrator and space enthusiast to co-author their debut children’s book.

Boeing’s Starliner spacecraft has landed in New Mexico, wrapping up a three-month test mission that faced technical issues and forced it to leave the two astronauts it carried temporarily stranded in space.

The spacecraft touched down at White Sands Space Harbor in the New Mexico desert at 04:01 GMT on Saturday. The two crew members it had flown to space – Butch Wilmore and Suni Williams – remained at the International Space Station (ISS) due to safety concerns with the craft.

[…]

Wilmore and Williams, whose mission was initially planned for just eight days, must return to Earth on a vehicle from Boeing’s rival SpaceX, owned by Elon Musk, in February 2025.

“It must be demoralising in a way when you’ve gone expecting to be up there for eight days and suddenly your mission turns into eight months,” Tanya Harrison, a fellow at the University of British Columbia’s Outer Space Institute, told Al Jazeera.

“At the same time this is a highly trained crew that knows that stuff like this can happen … they’re trained, they’re ready,” she said.

Some airlines are offering special flights to see April’s total solar eclipse, giving passengers a unique opportunity to witness the astronomical event from 30,000 feet.

The April 8 eclipse — when the moon passes between the Earth and sun, blocking out the sun’s rays — will pass over North America, and those in the right place will spend about 4-and-a-half minutes under the cloak of darkness. A lucky few will have the opportunity to observe the eclipse’s totality for longer as they soar through the sky chasing the early night.

Southwest Airlines and Delta Air Lines are operating flights that will follow the eclipse’s path of totality in America. The Delta flight was so popular among astronomy enthusiasts that the flights sold out in 24 hours, prompting the airline to add a second. This next total solar eclipse visible from the contiguous United States won’t occur until 2044.

[…]

Alaska Airlines in 2017 operated a special invitation-only flight that gave passengers an unreal look at the eclipse. Although the airline isn’t offering flights that chase this year’s eclipse, it’s offering flights to destinations that fall in the eclipse’s path of totality to get space nuts in the right place.

Tanya Harrison, a planetary scientist who works at the Earth and Planetary Institute of Canada, was one of the experts on the 2017 flight who took in the eclipse from the skies. She has also witnessed a nearly total eclipse in Arizona and said viewing it from an airplane “was hands down probably the coolest thing I’ve ever gotten to do, including working on Mars Rovers.”

“There’s something about space that fascinates everyone,” she said. “The sky is a shared experience. We can all look up and see what’s going on.”

Mars looms large in the scientific imagination, as well as in fiction. Of all the worlds of the solar system, it’s the only one Earth-like enough for exploration with Earth-like tools: Its atmosphere is thin and transparent, its surface is dry and cold, and it’s close enough for regular study. From telescope eyepieces, we’ve probed the Red Planet for centuries. And over the past 50 years, we’ve even sent instruments for a closer look.

However, in geological terms, that’s just a sliver of time. Mars’s deep history remains a mystery.

Last weekend, over 10,000 of you came together to celebrate the power of human storytelling. Here are a few highlights.

We just hosted our first-ever virtual conference: Medium Day.

Like Medium itself, the day was full of stories worth telling and listening to. Authors shared authentic, personal points of view. Publication editors gathered their communities for inspiration and collaboration. Readers and writers learned about everything from humor writing to software development to cartooning to space exploration. Illustrators drew live cartoons. Scientists shared original research. Entrepreneurs offered practical wisdom. And so much more.

Most of all, Medium Day was a celebration of the communities you all have built with each other. In the words of writer Amy Sea, “My initial takeaway from Medium Day was we’re storytellers above everything else, but we’re also a community. The only way we can get better is to honor that.”
