Gizmodo’s Ellyn Lapointe reports on a new paper from Associate Prof. Areg Danagoulian, which offers a  solution to verifying satellites aren’t carrying hidden nuclear weapons in space: an inspector satellite able to indicate the presence of uranium from neutron signals via sensor technology. Danagoulian’s proposal seeks to fill the gaps of The Outer Space Treaty (OST), established in 1967 and signed by 118 countries to ban nuclear weapons in space, which “has always lacked robust means of verification for space-based nuclear threats,” says Danagoulian. 

In a new study, Associate Prof. Areg Danagoulian proposes a satellite-based sensor that could monitor suspicious craft for signs of nuclear activity in space with 99% accuracy, reports Andrew Paul for Popular Science. “You can fake intelligence, but you can’t fake physics,” says Danagoulian. “The goal right now is to get national labs to use this work for their own research, and to get policymakers to seriously consider this technology as a potential part of national technical means.” 

Scientific American’s Adam Kovac highlights a paper by Associate Prof. Areg Danagoulian that proposes a satellite to detect and police hidden nuclear weapons in space by detecting spallation, the ejection of neutrons, from the bombardment of high energy protons, and uranium atoms. “If you detect those neutrons, that itself can be a telltale sign that there is an unusual amount of uranium on the satellite, and it’s most likely to be a nuclear weapon,” Danagoulian says.

Prof. Paul Lozano and alumna Amelia Bruno PhD ‘25 join John Batchelor, host of the "Hotel Mars” podcast, to discuss their work developing a new propulsion system that could improve small satellite mobility. “This technology [electrospray thrusters] came from our own research on how to miniaturize propulsion for small satellites,” says Lozano. “There is a big need to actually provide these little satellites with mobility, so that we can actually explore space and use it more effectively.” 

Associate Prof. Zachary Cordero speaks with Live Science reporter Larissa G. Capella about why cold welding—a process in which metals fuse together— can easily occur in space and the hazards it can pose. “If there is cold welding, things can become stuck in place,” says Cordero. “If you have a deployable structure and there's cold welding, you might freeze the mechanism, or a door might become locked, or something might become immobilized, which you don't want.” 

Prof. David Kaiser joins GBH “Particles of Thought” podcast host Dr. Hakeem Oluseyi to discuss his hunt for primordial black holes. “It’s a lot easier to find stuff coming off of a very bright, hot source, than a cold, dim one. So, the Hawking temperature of a black hole that has the same mass as our sun, or a little bigger would be so cold we would literally never be able to measure [its] radiation,” says Kaiser. “You’ll never see it [Hawking Radiation] from stellar collapse black holes, you’ll never see it from supermassive black holes, or even colder. The only hope to ever see it would be a smaller mass black hole.”

Prof. Richard Binzel goes interstellar and chats with Boston Globe reporter Nick Stoico about the science behind the meteor that exploded over Cape Cod Bay recently, noting that the event offered a rare opportunity for people to connect with a phenomenon that usually goes unnoticed. “It’s great when people find a connection to the greater universe,” said Binzel. “It’s a great perspective to think beyond the surface of the Earth.”

Prof. Richard Binzel shares his insights into the recently discovered school-bus sized asteroid that will fly by Earth next week with CNN reporter Jacopo Prisco. “2026JH2 will pass safely by the Earth,” said Binzel. “This is actually a rather normal occurrence, car-sized objects pass between the Earth and the Moon every week. At the size of a school bus, these pass through our neighborhood several times per year. We are only recently developing surveys that are sensitive enough to see them.”

Researchers from MIT have created a new model that can predict wave behavior on different planets, reports Kristen French for Nautilus. “On Earth, waves form as wind drags across bodies of water, pushing unevenly on their surfaces. As the waves lengthen, and the distance between crests grows, the waves are increasingly driven by the force of gravity rather than by surface tension,” French writes. “On faraway planets, the size of the waves would depend not only on the strength of gravity and the speed and direction of the wind, but the density of the atmosphere, the viscosity of the liquid in the oceans and lakes, as well as the depth of the bed. All these factors were fed into the PlanetWaves model.” 

MIT scientists have developed a new model, dubbed "PlanetWaves," that predicts wave behavior on different planets, showing that the "smallest gust of wind on Titan could generate huge, roiling waves across seas of hydrocarbons," reports Andrew Paul for Popular Science. “PlanetWaves is far more than a novel simulator,” writes Paul. “Calculating fluid behaviors on distant planets and moons could help inform engineers building new spacecraft and probes.”

Prof. Richard Binzel speaks with CBS Boston about the success of the Artemis II mission and the future of space exploration. "It's exciting we have humans back in space again," Binzel shared. "It's a real test of a spaceflight system. Surviving reentry and landing safely. That's the real accomplishment here. Showing we can go to the moon but also come back safely."

Jennifer Eagen of WCVB-TV highlights MIT Space Week, an annual series of events across MIT focused on space exploration and the space industry. Eagan notes that one of the themes for this year’s event is the space economy. "Having humans land on the moon, having built a base on the moon, learning how to operate there so eventually we can go to Mars," said keynote speaker Terry Virts, former commander of the International Space Station. "I would love to see all those things happen that would be a huge success for America and for the world, for all of humanity."

Using technology developed at MIT’s Lincoln Laboratory, the Artemis II astronauts are using lasers to send high-resolution video and images back to Earth, reports Hanna Ali for WBUR. Bryan Robinson, the leader of the Lincoln Laboratory Optical and Quantum Communications Group, explained that laser beams allow them to direct more energy at a target receiver. In other words, "you can communicate at higher data rates," Robinson said.

MassLive reporter John Micek writes about how the Artemis II astronauts are using optical communications technology developed at MIT Lincoln Laboratory to send high-resolution video and images of the lunar surface back to Earth. 

The stunning images of the moon and Earth being shared by the Artemis II crew have been made possible thanks to new optical communications technology developed by researchers at MIT’s Lincoln Laboratory, reports Emily Maher for WCVB-TV. "It was just awe-inspiring to think humans haven't seen the Earth from pole-to-pole in over 50 years, and being part of helping to make that happen is very cool," said Corrie Smeaton, associate group leader of the Optical Engineering Group at Lincoln Lab.
