The Legacy of Spirit: 5 Major Contributions to Mars Science (Medium)

20 years ago today on on June 10, 2003, NASA’s Spirit rover lifted off from Cape Canaveral and began its 7-month journey to Mars. It left Earth one month before its twin, Opportunity as part of the collective “Mars Exploration Rovers” mission. At that time, only one rover had successfully operated on the surface of Mars*—the microwave-sized Sojourner, which arrived in 1997 onboard the Pathfinder lander. This landing was just months after the arrival of NASA’s Mars Global Surveyor spacecraft in orbit. Beyond these two missions however, the 1990s/early 2000s weren’t kind to humanity’s attempts to get to the Red Planet.

5 Ways Companies Can Create Better Workplaces for Women (Medium)

For International Women’s Day, I posted a call to action on Twitter for the space sector, since it’s the realm I inhabit:

In the replies, someone asked for ideas on how companies can take actions, which was fantastic to see. Here are five suggestions that can help not only women, but anyone from underrepresented groups, thrive in the workplace:

“Good Night Oppy” Tells the Human Story of Robotic Space Exploration (Medium)

An Opportunity operations team member’s reaction to a new documentary about an old friend.

January 2004: I was in my sophomore year of college, studying astronomy at the University of Washington. The Sojourner rover had me hooked on the Red Planet from the day it landed in the summer of 1997. The moment that rover took its first drive onto the martian surface, my entire life became focused on the goal of working on Mars missions. Since planets are in space, I figured an astronomy degree would be the right first step.

But that winter morning, I wasn’t buried in a textbook. My attention was wholly transfixed on the television, nervously waiting to see if the Spirit rover was going to successfully land on Mars. In the time since Pathfinder, NASA’s luck hadn’t been going well…they’d lost both the Mars Polar Lander and the Mars Climate Orbiter in rapid succession. If the twin Spirit and Opportunity rovers weren’t successful, it could be the death knell for Mars exploration. Thankfully, both rovers landed within days of each other, and began their planned 3-month expeditions on opposite sides of the planet.

I never would’ve guessed that four years later, I’d be working with those same rovers. And I certainly never would’ve guessed that nearly a decade after that, I would still be working on Opportunity, and even be on shift the day we lost her signal for the last time.

10 Amazing Things Humans Did in Space in 2021 (Medium)

While this year may have sucked pretty hard on Earth, some pretty cool stuff happened in (and/or near) space in 2021. And while robots and rockets tend to steal the show, all of those bits of technology were designed, built, and operated by humans! Let’s look back at the past year.

It’s Time to Reclaim the Narrative Around Space from the Billionaires (Medium)

With the “billionaire space race” taking center stage in the media over the past few months, we’ve lost sight of why so many people are passionate about space.


This morning, Jeff Bezos’ rocket company Blue Origin launched four people into space, including Star Trek’s own Captain Kirk, William Shatner*. While this flight only lasted mere minutes, the impact on Shatner was abundantly clear as soon as he stepped out of the New Shepard crew capsule after touchdown. Bezos walked up to Shatner and asked how the experience was, to which he replied, “In a way, it’s indescribable.” And as he starts to try to articulate what was most unexpected to him…

…Bezos turns away, interrupting him to pop a bottle of champagne and cheer.

9 Big Discoveries by Curiosity for its 9th Landiversary (Medium)

Nervous Mars scientists around the world watched with bated breath as the behemoth Curiosity rover began its descent toward the surface of the Red Planet, known as the “Seven Minutes of Terror.”

We’d never sent something this size to land on Mars. We’d never used anything like the Skycrane to land on another world.

This was an audacious mission, and we all knew it.

Thankfully for all of us—and probably for the continued future of NASA’s Mars Exploration Program in general—the Skycrane system worked flawlessly, and Curiosity touched down at its permanent home in Gale Crater on August 5, 2012.

Gale Crater was chosen as the landing site for the rover based on satellite data suggesting the crater may have contained a lake around 3.5 billion years ago. While the water is long gone, its disappearance left behind a plethora of clays, sulfates, and other sedimentary rocks, all containing clues as to the martian environment when the lake was in existence. Curiosity’s mission goal was to look for signs of “habitability”—key things life as we know it would need to survive. Nine [Earth] years into its mission, it has revealed many important insights into the history of Mars. In celebration of its ninth landiversary, here are nine key discoveries from the rover so far:

Surviving Grad School: 3 Tips Before You Even Apply (Medium)

Graduate school is hard. Not going to sugar coat that. But it can also be a truly amazing and unique time in your life, and it doesn’t necessarily have to be miserable on top of being difficult. Here are some things you can do and think about before you even start applying to Ph.D. programs* that can help make the experience better—and hopefully something that makes you grow as a person and as a researcher:

*And if you’re on the fence about whether getting a Ph.D. is right for you in the first place, check out this other article.

The International Impact of the Apollo 11 Moon Landing (Medium)

The Space Race might have been America versus the Soviets, but how was the race viewed by the rest of the world?

On July 20, 1969, American astronauts Neil Armstrong and Buzz Aldrin became the first humans to set foot on a celestial body beyond Earth while Command Module Pilot Michael Collins kept dutiful watch from orbit overhead. Set against the backdrop of the Cold War and a “space race” between the United States and the Soviet Union, this amazing achievement could have easily been touted as a win for the U.S., laden with patriotic messages of America being the first to land people on the Moon.

I never thought being queer impacted my professional life as a scientist. I was wrong.(Medium)

For years, I’ve been quite frank and open on social media (mainly Twitter) about a lot of aspects of my life and professional career as a scientist: How having a physical disability has impacted things, my experiences with harassment that nearly drove me out of the field, making the shift from academia to industry, and more. But my gender identity and sexuality are never things I really touched on directly because I didn’t think it affected my professional life—and the things I had made the decision to talk about on social media were pretty much all related to my career. When it came to my personal life in terms of things like my family or who I dated, I very intentionally kept that separate because none of those people had signed up to be in a public spotlight the way that I’d chosen for myself.

It’s not something I ever kept secret, mind you. I just felt like if it didn’t impact my professional life the way it might have for some other people who were more publicly and vocally out, then those were the people who could speak to those experiences better than I could. While being queer didn’t feel like it directly impacted my daily life in a professional sense, I did recognize that I wasn’t able to fully relate to some of the experiences of women in the field.

Ingenuity Gets an Upgrade on Mars (Medium)

The tiny 4-pound (1.8 kg) helicopter that hitched a ride to Mars with NASA’s Perseverance rover just got a mission upgrade. Initially planned as a “technology demonstration” to prove whether or not powered flight was possible in the thin martian atmosphere, Ingenuity surpassed all expectations on the—at the time of writing—four flights it has successfully conducted thus far in its short tenure on Mars. Thanks to that success, Ingenuity will now be put through some additional paces, getting an upgrade from a technology demonstration to an operational demonstration.

How Space Benefits Canadian Life on Earth (Medium)

As a scientist who works on robots that we send to other planets, I often hear complaints about how much money is spent on “space.” Space is viewed as this futuristic pipe dream, the realm of eccentric billionaires with money to burn. Many don’t see how money spent on “space” has any benefit to humanity, especially with pressing matters like war and poverty here on the ground.

And these are absolutely valid concerns, don’t get me wrong.

But space, like all of science, is thoroughly integrated with our society. Space is here and now. Space is completely entrenched in our everyday lives as Canadians to the point that we don’t even see it. At this very moment, thousands of satellites for everything from communications to navigation to imaging are flying over our heads. And in Canada, each one of us uses these satellites in some fashion an average of 20 to 30 times every single day.

For Earth Day: Ten Stunning Views of Earth from Space Missions (Medium)

Most people are probably familiar, even if not by name, with the iconic “Earthrise” and “Blue Marble” view of Earth taken by Apollo astronauts on their journeys to the Moon. Apollo 8’s Earthrise, taken on Christmas Eve in 1968, is often referred to as one of the catalysts that led to the environmental movement and the creation of Earth Day. Since then, many other space missions have captured photographs of Earth on their way to their final destinations across the Solar System. In honour of Earth Day, let’s take a look at ten of the most stunning views these spaceships have given us.
