Prof. Nicholas de Monchaux speaks with New York Times reporter Vanessa Friedman about NASA’s newest spacesuit. The suit is “the costume for the drama we project into space,” says Monchaux. “[The way we] put ourselves into the heavens.”
MIT scientists have uncovered evidence that wildfire smoke particles can lead to chemical reactions in the atmosphere that erode the ozone layer, reports Margaret Osborne for Smithsonian Magazine. “From a scientific point of view, it’s very exciting to see this brand new effect,” says Solomon. “From a planetary point of view… it would be just tragic to have mankind screw up solving the ozone hole by deciding that we’re going to [allow] a lot more of these fires if we don’t mitigate climate change.”
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?”
Stephen Bowen MS ’93 and Warren Hoburg BS ’08 have joined the Crew-6 mission to the International Space Station (ISS), reports Susannah Sudborough for Boston.com. During their six-month period aboard the ISS, which began on March 2, “they will conduct over 200 science experiments and technology demonstrations,” writes Sudborough.
Daily Beast reporter Meredith Bagby spotlights the life of Ron McNair PhD ’76 and his legacy as one of NASA’s first black astronauts. “Astronaut, saxophonist, and karate black belt Ron McNair overcame an impoverished childhood in segregated Lake City, South Carolina to earn a Ph.D. in physics from MIT and become one of NASA’s first Black astronauts,” writes Bagby. “Although Ron’s path to NASA was nearly derailed because of systematic racism and inequality, he found inspiration in the Black leaders around him and persevered.”
Ronald McNair PhD ’76 was a part of NASA’s class of 1978, which was the first group of astronauts to include women, people of color, and scientists, reports Alexandra Witze for Nature. The class of 1978 “was a time of huge change for NASA,” writes Witze. “It was time for a new type of astronaut for a new type of spaceship.”
Prof. Sara Seager and her colleagues write for Physics Today about how the SpaceX Starship could help transform astrophysics missions. “Assuming it is successful, Starship will dramatically enhance our space capabilities in ways that will qualitatively alter how astrophysics missions can be built,” write Seager and her colleagues.
Research scientist Mary Knapp and her collaborators are working on a concept for The Great Observatory for Long Wavelengths (Go-LoW), a space-based observatory comprised of small satellites aimed at making low-frequency radio waves visible, reports Ashley Strickland for CNN. “I learned back in my undergrad days that there was this part of the spectrum we couldn’t see,” Knapp explains. “It really just struck me that there was this unexplored part of the universe, and I want to explore this part of the sky for the first time.”
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.
Research Scientist Mary Knapp’s proposal for a Great Observatory for Long Wavelengths (GO-LoW), a space-based observatory consisting of thousands of satellites that could study the magnetic fields of distant and rocky exoplanets, has been selected for NASA’s Innovative Advanced Concepts programs, writes George Dvorsky for Gizmodo.
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.”
