Michigan Governor Gretchen Whitmer gave the Canadian oil company Enbridge until May 12th to shut down the segment of the Line 5 pipeline that runs along the Straits of Mackinac. Enbridge has filed a federal lawsuit challenging the order. The question remains: how would Enbridge shut down the controversial pipeline and construct a replacement tunnel?

As the deadline approaches, University of Michigan engineering researchers offered insights into how the company might go about doing that, and also how they might construct a tunnel under the lakebed for a replacement section of the line.

If all goes according to plan, plenty of eyes will be on Mars on February 18th, the day NASA’s Mars 2020 mission is set to touch down on the Red Planet’s surface.

.

Late in 2019, just months before the U.S. plunged into full-on, COVID-19 life, NASA tapped Mechanical Engineering Assistant Professor Jesse Capecelatro and his team to help study the particles that are stirred by the landing of a spacecraft. The rockets that fire on a typical spacecraft landing kick thousands of tiny surface particles into motion, and those particles can create trouble for any multi-million dollar craft even under the best of circumstances.

For the Mars 2020 space mission and other landings scheduled over the next few years, the University of Michigan crew will collect data and create physics-based models that can be incorporated into codes used by NASA. They’ll help predict what happens when a spacecraft attempts to land millions of miles from home.

S1 E4 - The Blue Sky Podcast

Evolution provided bacteria with a mechanism to overcome our antibiotics, and each time we introduce a new antibiotic, they get faster at becoming resistant to it. At the same time, it can take 14 years and billions of dollars to bring a new one to market.

Angela Violi, professor of mechanical engineering, is leading a coalition of chemical engineers and biologists trying to change the game by developing antibiotics in a new way. They want to design nanoparticles to exploit weaknesses in the target pathogens. Not only could they work better, they could make it to market faster.

The Blue Sky Podcast is an award winning limited series from RE: Engineering Radio and the University of Michigan College of Engineering. We’re following four research projects in critically important areas of global consequence.
