Prof. Richard Binzel speaks with Popular Science reporter Briley Lewis about how frequently asteroids come close to Earth. "I would be worried if we weren’t taking the asteroid survey challenge seriously,” says Binzel. "NASA and its funding sources are stepping up to the adult responsibility of doing the necessary searching to make sure our asteroid future is secure.”
Prof. Paulo Lozano speaks with Boston Globe reporter Travis Anderson about NASA’s recent asteroid test, which successfully shifted the orbit of a harmless asteroid. The mission had a “truly inspirational result,” says Lozano. “We’re getting closer to hav[ing] the ability to protect our planet from one of the most destructive forces in nature.”
Prof. Richard Binzel speaks with CBS News reporter David Pogue about asteroids and the Torino scale, a 10-point danger scale for asteroids that he created. "All the objects [asteroids] we know of today reside at zero or one, which simply means they're so small that they don't matter, or that we know for sure there's no impact possibility," says Binzel.
Prof. Paulo Lozano speaks with 7 News about NASA’s Double Asteroid Redirection Test (DART) spacecraft, which slammed into an asteroid Monday night, demonstrating how an asteroid threatening Earth could be deflected. Lozano notes that there are millions of space rocks in the solar system, “many of them are characterized but the grand majority are not, and these objects can basically take out a city. Being prepared for these kinds of events will be very important.”
Andy Rivkin ’91 speaks with Boston Globe reporter Andrew Brinker about his work on NASA’s DART mission, which is aimed at testing whether a rocket could be used to help steer an asteroid away from Earth. “I’ve always been interested in stars and space and planets since I was a kid,” said Rivkin. “At MIT, I was in the earth, atmospheric, and planetary sciences department, and that’s when I started looking at asteroids. And then as a graduate student, I studied asteroids. And then I ended up doing my dissertation on them. It sort of all started [at MIT].”
Forbes contributor Bruce Dorminey writes that a new study by MIT scientists finds that the surfaces of carbonaceous asteroids may be much more rocky than previously thought. “This news is important for planetary science because we need to sample asteroids to answer fundamental questions such as how the solar system formed and how life came to be on Earth, says postdoctoral fellow Saverio Cambioni.
Gizmodo reporter George Dvorsky writes that astronomers have found two red asteroids, which resemble objects typically found beyond Neptune, in the main asteroid belt between Mars and Jupiter. “This finding suggests some asteroids in the main belt formed in the outer solar system, and that a population of these objects is likely to exist within the main belt,” writes Dvorsky.
Alumnus David Oh ’91, SM ’93, ScD ’97 speaks with Ars Technica reporter Eric Berger about his work serving as the technical lead for NASA’s Psyche mission, a robotic spacecraft that is set to voyage to a metallic asteroid using a propulsion technology called Hall thrusters. Berger writes that Oh, who worked on Hall thrusters as a graduate student at MIT, is “eager to learn whether Psyche may be the core of something that could have become a planet during the early days of our Solar System but ultimately didn't.”
CBS Boston reporter Juli McDonald spotlights how NASA's ORISIS-Rex spacecraft carried a key imagine instrument, designed and built by students from MIT and Harvard, on its mission to sample the surface of the asteroid Bennu. Prof. Richard Binzel, co-investigator for the mission, explains that, the device was developed to “measure the asteroid in X-ray light, which is part of the process of figuring out what the asteroid is made out of.”
When NASA’s OSIRIS-Rex spacecraft touched down on the asteroid Bennu, onboard was the REgolith X-Ray Imaging Spectrometer (REXIS), a device built by students from MIT and Harvard, write Breanne Kovatch and Andrew Stanton for The Boston Globe. “We as scientists feel the drive of curiosity and the thrill of exploration and it’s humbling and satisfying to think that we can share that sense of exploration with the world,” explains Prof. Richard Binzel, a co-investigator for the mission.
