This is the future Arizona State University graduate Conor Kennett hopes to build in his career. 

“Cities like Detroit shrunk because they did not have a long-lasting sustainable industry to keep their economic growth going and so they suffered,” Kennett said. “I want to create something that will be long lasting while also being sustainable for the environment.”

Kennett, a first-generation student from Minneapolis, is graduating this spring with an online Bachelor of Science in urban planning from the College of Liberal Arts in Sciences. He’s also earned a minor in sustainability and a certificate in geographic information science. 

Kennett was able to attend college thanks to the Starbucks College Achievement Plan, a first-of-its-kind partnership that provides qualifying Starbucks partners with 100% tuition coverage to earn an undergraduate degree through ASU Online

“I chose ASU because Starbucks gave me a scholarship for it,” Kennett said. “Without that scholarship, I would have never gone to college. I am so glad I did though because ASU has been an amazing experience and the teachers and faculty have been incredible in my journey.”

Read on to hear more from Kennett about this ASU experience and advice for current students. 

Question: What accomplishment are you most proud of as an ASU Online student?

Answer: I am super proud to be graduating with honors and having made the dean’s list three semesters considering for me school has always been a challenge. I was a C student in high school and never saw myself as someone who could even get B’s let alone A’s. I just needed to find the subjects that were interesting to me I guess!

Q: What was your “aha” moment when you realized you wanted to study the field you majored in?

A: I think when I started talking to a coworker about urban planning as he was attending ASU for the program it started to click for me a bit, but then after talking with someone at ASU about the program and what sort of career paths it could lead to is when it really started to sink in. I think city design is really interesting and all of the factors that go into it fascinate me. There are certainly some dream projects that I want to work on at some point if I can.

Q: What’s something you learned while at ASU — in the classroom or otherwise — that surprised you or changed your perspective?

A: I think taking classes that were unrelated directly to my field really brought me some perspective and one class, in particular, was about extreme weather. The class made us look at extreme weather events occurring around the world each week and I remember looking into major flooding that was happening in Iran. I didn’t think it flooded in Iran, but they have seasonal floods that are really destructive and that year they were particularly bad. It helped to alter my perspective in a way that everyone in the world is dealing with issues and we (the United States) can't think it's all about us.

Q: Which professor taught you the most important lesson while at ASU?

A: I think Professor Ronald Dorn was probably the most influential professor at ASU though honestly there were many. He really showed me that learning can be fun and taught me how to crave knowledge. Something about his candor and his passion for being an educator really changed me as a student. I do not think I would’ve completed my degree without his influence and I hope I can express that in person at some point because I want him to know how pivotal his role was in my education.

Q: What was your favorite spot for power studying? 

A: I do all my homework and study at my desk in my apartment because secretly I am a hermit. It is my comfort zone and I filled my space with lots of nice stuff so I don’t like leaving it very often.

Q: What’s the best piece of advice you’d give to those still in school?

A: Find your passion and then work for it. The things you will be passionate about will not come to you easily and no one is born for it. You don’t decide to be a doctor on a whim, you work towards it with a fervor and unrivaled passion because you care about people. You don’t become a lawyer because it sounds cool, you choose that path because you care about justice and equality. Never give up on yourself and keep going because it will be worth it to finish that degree. This is the best investment you can make in life and it is worth it.

Enigmatic rocks on Mars show evidence of a violent origin

April 25, 2022

Determining the history of Mars, how it formed and evolved over time, has been a goal of both orbiter and rover missions to the Red Planet for decades.

Analyzing data from several of these Mars missions, a team of researchers led by Steve Ruff of Arizona State University’s School of Earth and Space Exploration has determined that enigmatic olivine-rich bedrock in Gusev crater and in and around Jezero crater may be a type of rock called “ignimbrite,” which is both igneous and sedimentary and forms as the result of cataclysmic explosive eruptions from immense volcanic calderas.  Outcrop of olivine-rich bedrock in Gusev crater observed with Spirit’s Panoramic Camera (Pancam) in 2005.

If the team is correct, this may lead to a better understanding of olivine-rich bedrock in other places on Mars and may also indicate a style of volcanism more common in Mars’ early history. The results of their study have been recently published in Icarus.

“There are lots of ideas for the origin of olivine-rich bedrock that covers large portions of a region called Nili Fossae, which includes Jezero crater,” Ruff said. “It’s a debate that’s been going on for nearly 20 years.”  

Exposures of bedrock rich in olivine and also carbonate link Gusev crater, explored 16 years ago by NASA’s Spirit rover, and the Nili Fossae region where the Mars 2020 Perseverance rover is currently exploring in Jezero crater. Both locations have the highest abundance of olivine yet identified on Mars. The similarities in composition and morphology of the widely separated olivine-rich rocks had not been investigated previously. Now it appears that they formed in a similar way.

Olivine is a common silicate mineral that comes from magma generated in the mantle of Mars (this same process occurs on Earth as well). So some kind of volcanic process is a reasonable explanation for the origin of the olivine-rich rocks on Mars. But scenarios ranging from lava flows to a giant impact dredging up olivine from the mantle had been proposed previously.  

Ruff and the team aimed to test a leading hypothesis involving ash gently deposited from volcanic plumes. But their observations revealed a much more violent history.

In particular, Ruff examined mosaics of images from the Mars rover Spirit’s Microscopic Imager (which is like a geologist's hand lens) and noticed rocks with an unusual texture. Ruff consulted an online library with images of rocks on Earth and came across some volcanic rocks with textures that looked remarkably similar to those in the mosaics from Mars.

“That was a eureka moment,” says Ruff. “I was seeing the same kind of textures in the rocks of Gusev crater as those in a very specific kind of volcanic rock found here on Earth.”

The images were from a type of rock called “ignimbrite,” which essentially is both igneous and sedimentary at once. Ignimbrites form as the result of flows of pyroclastic ash, pumice and blocks from the largest volcanic explosions known on Earth.

“Imagine a ground-hugging cloud of hot gases and nearly molten ash and pumice flowing through the landscape for dozens of miles and piling up in layers up to hundreds of feet thick in just a few days,” Ruff said.

Following their emplacement, ignimbrite deposits slowly cool over months or years. This leads to intricate networks of fractures known as cooling joints, which form as the thick piles of ash and pumice contract. Ruff recognized notably similar fracture patterns in the olivine-rich bedrock deposits on Mars, adding to the evidence for an ignimbrite origin.

On Earth, ignimbrites are found in places like Yellowstone National Park in the Western U.S. The yellow-hued rocks are ignimbrites from a huge volcanic caldera that formed during a period beginning about 2.1 million years ago and is now filled in.

“No one had previously suggested ignimbrites as an explanation for olivine-rich bedrock on Mars,” Ruff said. “And it’s possible that this is the kind of rock that the Perseverance rover has been driving around on and sampling for the past year.”

Mars has the biggest volcano in the solar system and lava flows that cover huge swaths of the planet, so volcanic rocks are a given. But only a few places had been suggested to contain ignimbrites, and until now only tentatively.

With this team’s new findings, it is possible that ignimbrites occur in both Jezero and Gusev craters. Other locations with olivine-rich bedrock also are candidate ignimbrite deposits, and all of them appear to have formed early in Mars history, during the first billion years or so.

“The olivine-rich composition is unusual for most ignimbrites on Earth, but there is evidence for this composition in the oldest ones. Now with the strong evidence for ancient olivine-rich ignimbrites on Mars, maybe this points to a style of volcanism, cataclysmic explosive eruptions of olivine-rich magma, that happens in the early geologic evolution of a planet,” Ruff said. “The answer in the case of Mars may come from rock samples collected by Perseverance and returned to Earth by future missions.”
