MIT researchers are leading three missions over the next decade to characterize Venus’ atmosphere for habitability, reports Bruce Dorminey for Forbes. “Understanding Venus is key to understanding exo-earths,” writes Dorminey.

USA Today reporter Zoe Wells spotlights the Mars MOXIE device developed by MIT researchers, which “has already made 122 grams of oxygen, comparable to 10 hours of breathable air for a small dog. MOXIE produced 12 grams of oxygen per hour at 98% purity, which exceeded NASA's original expectations.”

Jasmin Moghbeli '05 is the mission commander for NASA’s SpaceX Crew-7 mission to the International Space Station, reports Russ Reed for WCVB-TV. “This marked Moghbeli's first trip into space since she was selected to be a NASA astronaut in 2017,” writes Reed. “Belief in yourself is something really powerful,” Moghbeli said before the flight.

Jasmin Moghbeli '05 is serving as mission commander on the SpaceX Crew-7 mission to the International Space Station, which includes astronauts from 4 different countries, reports Jackie Wattles for CNN. “We are extremely proud — and I know I personally am humbled — to be a member of this incredible crew, where if you look at our four patches you’ll see a different nation’s flag on each one,” Moghbeli said of the flag patches adorning the astronauts’ suits. “We hope this represents what we can accomplish when we work together in unity and cooperate together. And we think this really is what the International Space Station is all about.”

For Jasmin Moghbeli ’05, who is serving as mission commander for the SpaceX Crew-7 journey to the International Space Station, the mission is about “determination, exploration and inspiration, especially to the next generation of girls like her twin daughters," reports Mark Strassmann for CBS News. Moghbeli notes that when her daughters see “the diverse crews that are going up there, they realize they can be part of this, whether it's becoming an astronaut or something else. They realize they can do it as well."

Writing for The Washington Post, graduate student Thomas Roberts underscores the importance of investing in new technologies to mitigate the risks posed by space debris. “Space operators can control how some large objects return to Earth. But this requires extra fuel reserves and adaptive control technologies, which translate into higher costs,” writes Roberts. 

MIT researchers have developed a new satellite observation technique that can gauge how fast rivers flowed on Mars billions of years ago and how fast they currently flow on Titan, Saturn’s largest moon, reports Talia Lissauer for The Boston Globe. “We can use these other worlds to help us understand what keeps planetary climate stable, or in some cases, what allows planetary climate to change really drastically over time like on Mars,” says Prof. Taylor Perron.

Popular Science reporter Jon Kelvey writes that astronomers from MIT and elsewhere recently captured views of a galaxy cluster as it existed when it was 5 billion years old, and found it is one of the few relaxed galaxy clusters from that time period in the cosmos. The findings “could be telling us that galaxies are forming at a younger age than we thought,” in the early universe, explains graduate student Michael Calzadilla. “That’s challenging our timeline of when things happened.”

Researchers from MIT have developed a new satellite observation technique that can help gauge the strength of ancient rivers on Mars and active liquid methane rivers on Titan, Saturn’s largest moon, reports Jamie Carter for Forbes. “What’s exciting about Titan is that it’s active, and on Mars, it gives us a time machine, to take the rivers that are dead now and get a sense of what they were like when they were actively flowing,” says Prof. Taylor Perron. “With this technique, we have a method to make real predictions for a place where we won’t get more data for a long time.”

Using a new satellite observation technique, researchers from MIT and elsewhere have determined the flow of dried-up rivers on Mars and currently active liquid methane rivers on Titan, Saturn’s largest moon. “Both kinds are of scientific interest because they could reveal the role rivers play in shaping the worlds’ environments,” reports Isaac Schultz for Gizmodo.

Postdoc Josh Borrow and his colleagues used simulations to explore how early-universe galaxies born inside alternative dark matter halos start out, and what happens as they grow, reports Lyndie Chiou for Scientific American. “The simulations also revealed a new discovery: a connection between alternative dark matter types and starbursts, periods of extremely rapid star formation inside a galaxy.”

Astrophysicist Frank Shu '63, who is credited with making pivotal contributions to our understanding of galaxies and star formation, has died at the age of 79, reports Douglas Lin and Fred Adams for Nature. “For the past dozen years, his concern about the climate crisis led him to study the use of molten-salt reactors to generate energy from nuclear waste and to convert waste biomass into inert products that can be sequestered, removing carbon from the atmosphere,” write Lin and Adams.

SpaceX Crew-6 Mission Commander Stephen Bowen MS ’93 recently answered questions from Cohasset Public School students live from the International Space Station, reports WBZ. "The Earth is always amazing to look at," Bowen told the students of his experience in space.

Prof. Nergis Mavalvala, dean of the MIT School of Science, and postdoc Victoria Xu speak with Nature reporter Davide Castelvecchi about the upgrades to the LIGO gravitational wave detectors that have significantly increased their sensitivity. “The improvements should allow the facility to pick up signals of colliding black holes every two to three days, compared with once a week or so during its previous run." 

Upgrades made to the LIGO gravitational wave detectors “will significantly boost the sensitivity of LIGO and should allow the facility to observe more-distant objects that produce smaller ripples in spacetime,” writes Pennsylvania State University Prof. Chad Hanna in a piece for The Conversation.
