Postdoc Saverio Cambioni speaks with Andrew Corselli of Tech Briefs about NASA’s DART mission, which was aimed at testing a method to protect Earth in case of an asteroid impact threat. “DART showed that it is technologically possible to intercept and impact a sub-kilometer asteroid, with limited prior knowledge of its shape and surface properties,” Cambioni explains.
Researchers from MIT have found that wildfire smoke can activate chlorine-containing molecules that destroy the ozone layer, writes Donna Lu for The Guardian. “The question in my mind is: is the man-made chlorine going to get … diluted and destroyed out of the atmosphere faster than global climate change is going to increase the frequency and intensity of this kind of fire?” says Prof. Susan Solomon. “I think it’s going to be a race.”
Axios reporter Jacob Knutson highlights a new study by MIT researchers that finds the smoke released by major wildfires likely reactive chlorine-containing molecules in the atmosphere, delaying the recovery of the hole in the ozone layer. The researchers developed a model that found smoke released by Australian wildfires “chemically depleted between 3% to 5% of the total ozone column in the Southern Hemisphere mid-latitudes in June and July of 2020.”
New Scientist reporter James Dinneen writes that a new study by MIT researchers finds the smoke from Australian wildfires “may have enabled hydrochloric acid to dissolve at higher temperatures, generating more of the reactive chlorine molecules that destroy ozone.” Research scientist Kane Stone explains that “satellite observations showed chemistry that has never been seen before.”
MIT scientists have found that the Australian wildfires in 2019 and 2020 unleashed remnants of chlorine-containing molecules in the stratosphere, expanding the ozone hole and suggesting that more frequent wildfires could threaten the ozone hole’s recovery, reports Dyani Lewis for Nature. “It’s like a race,” says Prof. Susan Solomon. “Does the chlorine decay out of the stratosphere fast enough in the next, say, 40–50 years that the likely increase in intense and frequent wildfires doesn’t end up prolonging the ozone hole?”
Prof. Steven Barrett speaks with New York Times reporter Paige McClanahan about the pressing need to make air travel more sustainable and his research exploring the impact of contrails on the planet’s temperature. “Eliminating contrails is quite a big lever on mitigating the climate impact of aviation,” said Barrett.
Astronauts aboard the International Space Station completed an experiment to test a system developed by researchers from MIT’s Space Exploration Initiative that would allow astronauts to build parts in space, reports Pranshu Verma for The Washington Post. The new system could allow astronauts to build and modify space stations “quicker, cheaper and with less complexity,” explains Ariel Ekblaw, director and founder of the Space Exploration Initiative. “It starts to unlock more opportunities for exploration.”
MIT researchers developed a new system to build gravity-defying spare parts in space that is currently being tested aboard the International Space Station, reports Rahul Rao for Popular Science. “The MIT group’s process involves taking a flexible silicone skin, shaped like the part it will eventually create, and filling it with a liquid resin,” writes Rao. “These are going to be our first results for a really novel process in microgravity,” explains Ariel Ekblaw SM ’17, PhD ’20, director of the Space Exploration Initiative.
Prof. Paulo Lozano speaks with Scientific American reporter Nadia Drake about the CubeSats NASA tested during the Artemis I mission. “There are not that many opportunities to actually go to deep space with CubeSats, so having more of those opportunities available—I think it’s a great thing for little satellites,” Lozano says. “I think there’s going to be a lot of things to be learned about how to design these spacecraft so that, in the future, we can design little spacecraft that can accomplish what big spacecraft can achieve.”
Ariel Ekblaw, director of the Space Exploration Initiative and founder of the Aurelia Institute, speaks with Fast Company reporter Rachael Zisk about accessibility needs for human spaceflight and the next generation of space stations. “The goal of democratizing access to space is to allow more people around the world to see themselves in that future,” says Ekblaw.
Astronomers have identified two Earth-sized exoplanets orbiting a red dwarf star 33 light years away, reports Jamie Carter for Forbes. “Both planets in this system are each considered among the best targets for atmospheric study because of the brightness of their star,” explains postdoc Michelle Kunimoto.
TechCrunch reporter Brian Heater spotlights multiple MIT research projects, including MIT Space Exploration Initiative’s TESSERAE, CSAIL’s Robocraft and the recent development of miniature flying robotic drones.
Gizmodo reporter Passant Rabie writes that researchers from MIT Lincoln Laboratory developed a tiny gold-coated satellite called the TeraByte InfraRed Delivery (TBIRD) system with the goal of beaming “down data at the fastest rate ever achieved by space lasers.”
A study conducted by Prof. Susan Solomon and her colleagues has found that unlike CFCs, smoke destroys the ozone in a more roundabout way, creating concerns due to the impact of the Australian bushfires of 2019-2020, reports Krystal Vasquez for EOS. “Because of the sheer scale of the event [the Australian bushfires] massive amounts of smoke penetrated the normally pristine upper stratosphere,” writes Vasquez.
Prof. Susan Solomon speaks with Wall Street Journal reporter Nidhi Subbaraman about her research and another recent study that provides evidence wildfire smoke poses a threat to the ozone layer. “It’s fair to say that, at least for a few months, these wildfires canceled out the last decade of all the efforts that we put in over the Montreal Protocol,” says Solomon. “I think there’s every reason to believe this is going to happen more often, and it’s going to act to slow down the recovery of the ozone depletion.”
