Jim Bell, Arizona State University
Editor’s note: On Feb. 18, NASA’s Mars 2020 mission arrived at the red planet and successfully landed the Perseverance Rover on the surface. Jim Bell is a professor in the School of Earth and Space Exploration at Arizona State University and has worked on a number of Mars missions. He is the primary investigator leading a team in charge of one of the camera systems on Perseverance. We spoke with him in late January for The Conversation’s new podcast, The Conversation Weekly.

As global emissions of greenhouse gas continue to rise, it is increasingly important for researchers and policymakers to identify exactly where and how much greenhouse gas is emitted and absorbed worldwide for global climate change mitigation. Over the past decade, Dr. Tomohiro Oda of the Universities Space Research Association (USRA) in Maryland has aimed to realize this need by combining emission data with night-time observations from satellites. Through this work, his team has now produced global maps that distinguish sources of carbon at unprecedented resolutions – high enough to identify variation across the regions where emissions are most intense: Earth’s cities.

Space lovers around the world are holding their breath for the landing of NASA’s Perseverance Rover on Mars on February 18th. After a 470.73 million kilometer (292.5 million miles) journey from Earth to Mars, Perseverance will join its fellow rovers Sojourner, Spirit, Opportunity, and Curiosity on Mars, and be part of a massive scientific endeavor to find signs of ancient life on the Martian surface.

Why there are no stars in space photos? Or in moon landing photos? Because, when you try to shoot a very bright object (for example, the Earth) and very dim objects (stars) in the same frame, you cannot properly expose both. To be able to see the stars, the bright object would have to be overexposed making it appear as a featureless white blob.

Ever wonder where all of your extra food scraps and garbage go once you throw them away? Food that is produced but not eaten ends up in landfills and creates methane, a greenhouse gas that is harmful to the environment. As landfills continue to overflow, it’s clear that taking steps to lower our carbon footprint is necessary.

When the coronavirus burst onto the scene, healthcare professionals and robotics experts partnered to implement out-of-the-box solutions to pressing needs. In Wuhan, China, a test-run of a field hospital staffed by robots took place. The machines, provided by tech company CloudMinds, delivered necessities and medicines and even entertained patients.

Ocean pollution is widespread, worsening, and poses a clear and present danger to human health and wellbeing. But the extent of this danger has not been widely comprehended – until now. Our recent study provides the first comprehensive assessment of the impacts of ocean pollution on human health.
