Asteroids

Prof. Richard Binzel speaks with CNN reporter Ashley Strickland about the trajectory of asteroid 2024 YR4. “YR4 presents a challenge because it is small and headed away. Telescopes on the ground can track it for a few more months. Then we’ll call (the James Webb Space Telescope) into service to track it even further, if needed,” says Binzel. “While certainty for 2024 YR4 missing the Earth is the outcome we expect, it’s not up to us. It’s for nature to decided. In fact, nature already has settled the question. We just don’t know that answer yet. That’s why our tracking efforts continue.”

Prof. Richard Binzel, Prof. Julien de Wit, and Research Scientist Artem Burdanov speak with NBC 10 Boston reporter Matt Fortin about their new asteroid-detecting method that will be used to track the newly discovered asteroid 2024 YR4 and help protect Earth. “By refining and applying their technique, my colleagues [de Wit and Burdanov] have basically turned the JWST into the most capable asteroid-tracking system in history,” explains Binzel.

In an interview with NBC News reporter Kathy Park, Prof. Richard Binzel, Prof. Julien de Wit, and Research Scientist Artem Burdanov provide insight into astronomer's efforts to learn more about asteroid 2024 YR4. “This is an object that merits tracking by astronomers, merits our attention and that’s simply what we are doing,” says Binzel. 

Research Scientist Artem Burdanov speaks with WBZ News Radio reporter Chaiel Schaffel about his team’s work developing a new detection method that could be used to track potential asteroid impactors like 2024 YR4 and help protect our planet. Burdanov and his colleagues used the new method to detect “138 asteroids ranging in size from a bus to the size of Gillette Stadium.” Burdanov explains that he and his colleagues "used a clever technique to find asteroids that are hidden in the noise.” 

MIT scientists have discovered the smallest asteroids known to exist in the Main Asteroid Belt between Mars and Jupiter, reports Alfredo Carpineti for IFL Science. “The team of researchers behind this new discovery cleverly reused images from the search for exoplanets,” writes Carpineti. “Stacks of images looking at the same distant star field were used with a technique called “shift and stack”, which aims to highlight possible movement in the foreground, like from an asteroid. They were able to find 138 asteroids in the decameter size range.”

Prof. Richard Binzel speaks with Washington Post reporter Lizette Ortega about Apophis – an asteroid estimated to fly past Earth in April 2029. “Nature is performing this once-per-several-thousand-years experiment for us,” says Binzel. “We have to figure out how to watch.”

Prof. Richard Binzel talks with Meghan Bartels of Scientific American about the importance of studying Asteroid Apophis – a sizeable space rock that will near Earth within “one tenth of the Earth-moon distance” in 2029. “It’s an incredibly rare event that an asteroid like Apophis would hit the Earth, but it’s better to be knowledgeable than to [be] caught unaware,” says Binzel, a planetary scientist Bartels notes has “spent years raising awareness about the scientific opportunities of the 2029 flyby.” 

Prof. Richard Binzel organized a centennial celebration for the Johnstown meteorite, which was seen crashing into Earth on July 6, 1924 in Weld County, Colorado, and later “became a link to understanding a whole class of meteorites,” reports Elizabeth Gamillo for Astronomy. “Binzel describes the Johnstown rock not as the meteorite that launched a thousand ships, but one that instead launched one major mission to the asteroid belt,” writes Gamillo. 

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.
