Smoke from Australian wildfires in 2019 and 2020 appears to have contributed to the breakdown of the ozone layer, according to a new study by MIT scientists, reports Sharon Udasin for The Hill. “The new study establishes the first direct link between wildfire smoke and ozone depletion,” writes Udasin.
Daily Beast reporter Miriam Fauzia writes that a new study by MIT scientists finds that smoke particles from wildfires are slowing the recovery of the ozone layer.
BBC News correspondent Helen Briggs writes that MIT scientists have found that increasing wildfires may slow the recovery of the ozone layer. "All the hard work that the world went to to reduce chlorofluorocarbons (ozone-depleting chemicals once used in aerosol sprays) is not paying off as well in the areas that experience extreme wildfires," explains Prof. Susan Solomon. "The best hope would be that we reduce global warming gases also and stop increasing the wildfires, but that's obviously more difficult."
A new study by MIT scientists finds that smoke emitted into the atmosphere from Australian wildfires in 2019 and 2020 resulted in depletion of the ozone layer, reports Donna Lu for The Guardian. The findings suggest “rising fire intensity and frequency due to the climate crisis may slow the recovery of the ozone layer.”
TESS, a NASA mission led and operated by MIT, has discovered over 5,000 planets candidates outside of our solar system, reports Ed Browne for Newsweek. “This time last year, TESS had found just over 2,400 TOIs (TESS Objects of Interest),” says postdoctoral associate Michelle Kunimoto. “Today, TESS has reached more than twice that number – a huge testament to the mission and all the teams scouring the data for new planets.”
MIT researchers have proposed a conceptual hovering rover that would use the moon’s static charge to stay airborne, reports Elizabeth Howell for Forbes. “We think a future [moon] mission could send out small hovering rovers to explore the surface of the moon and other asteroids,” says graduate student Oliver Jia-Richards.
MIT researchers have tested the concept for a hovering rover, a spacecraft that could use the moon’s electric field to levitate over its surface, reports Tatyana Woodall for Popular Science. Graduate student Oliver Jia-Richards explains that the team’s idea for a disc-like rover “potentially provides a much more precise and easier way of maneuvering on these rough terrain and low gravity environments.”
MIT researchers have proposed testing a concept for a levitating rover that could operate by using the moon’s electric field, reports Andrew Liszewski for Gizmodo. Liszewski writes that “the researchers believe a levitating rover powered this way could potentially float even higher, or potentially be built heavier with additional scientific instrumentation on board.”
Prof. Sara Seager speaks with New York Times reporter Dennis Overybye about the James Webb Telescope. Seager is part of a team that is planning to use the telescope to observe an exoplanet named Trappist-1e to determine if the planet has an atmosphere.
CNN reporter Ashley Strickland writes that NASA’s Transiting Exoplanet Survey Satellite (TESS), an MIT-led mission, has discovered an exoplanet approximately the size of Mars where a year lasts for about eight hours. “Astronomers are eager to learn more about these small planets that quickly spin around their stars in less than 24 hours because they are not sure how they form and end up in such an extreme orbit,” writes Strickland.
A team of astronomers, including MIT researchers, has discovered an ultrahot Jupiter that orbits its star in just 16 hours, reports Robert Lea for Newsweek. “Ultrahot Jupiters such as TOI-2109b constitute the most extreme subclass of exoplanet,” explains former MIT postdoc Ian Wong. “We have only just started to understand some of the unique physical and chemical processes that occur in their atmospheres – processes that have no analogs in our own solar system.”
Prof. Danielle Wood and her team are developing new techniques to use satellite data to monitor and manage environmental problems in remote areas, including an invasive weed growing in parts of Africa, to help inform local decision making, reports Ramin Skibba for Wired. “Our goal is to make it an affordable and operationally feasible thing for them to have this ongoing view, with data from space, data from the air, and data from the water,” says Wood.
Writing for The Washington Post, Prof. Erik Lin-Greenberg and Theo Milonopoulos of the University of Pennsylvania explore the challenges posed by governments no longer controlling sensitive security information. “As commercial imagery satellites proliferate in orbit, policymakers around the world will increasingly need to grapple with the ways the technology can reveal national security secrets,” they write.
Prof. Danielle Wood speaks with Andrew Browne of Bloomberg TV about her work focused on using space technologies as a way to advance the U.N. Sustainable Development Goals. Wood emphasizes how space “is a platform for serving the broad public. We use satellites to observe the environment and the climate, we use satellites to connect people across different parts of the Earth, and they give us information about our positions and our weather. All of these are broad public goods that really can serve people across the world all at once.”
Alumnus Mike Cassidy S.B. ’85, S.M. ’86 founded a company called Apollo Fusion, which makes electrical propulsion systems for small satellites, reports Tim Fernholz for Quartz. Apollo Fusion’s thruster were set to be deployed in space for the first time on June 29 by a SpaceX Falcon 9 rocket.
