3 Questions: Strengthening Our Planetary Defenses | MIT News
The Realities and Innovations in Planetary Defense
When people envision asteroids, the mind often drifts to dramatic portrayals found in blockbuster films like “Armageddon.” The truth, however, is less about global catastrophe and more about the myriad smaller asteroids that can impact our daily lives. While colossal, kilometer-sized asteroids are rare events occurring every tens of millions of years, smaller decameter-scale asteroids—about the size of a building—strike Earth with alarming regularity, roughly every few decades. As astronomers refine their techniques for detecting and tracking these smaller objects, the necessity for planetary defense grows ever more salient, particularly for protecting critical space infrastructure such as GPS and global communications.
MIT’s Role in Planetary Safety
In an exciting development, a team at MIT, led by Associate Professor Julien de Wit and Research Scientist Artem Burdanov, has pioneered a groundbreaking asteroid-detection method. Utilizing the incredible capabilities of the James Webb Space Telescope (JWST), they can now identify and characterize these smaller asteroids, extending their reach deep into the main asteroid belt. This innovation marks a significant leap forward in planetary safety, as it enables scientists to track potential asteroid threats more effectively.
Recently, they co-led observations of 2024 YR4, which gained attention when it was first discovered. Their findings reassured the public that this particular asteroid would not collide with the Moon—an event that could significantly disrupt Earth’s satellite systems.
What is Planetary Defense?
Burdanov explains that planetary defense encompasses the scientific and engineering endeavors aimed at preventing asteroids and comets from hitting our planet. Historically, the focus has been on larger asteroids, but the advent of new observational techniques allows for a broader scope that includes the monitoring of much smaller asteroids capable of causing disruptions.
De Wit adds that while larger asteroids like those thought to have caused mass extinctions maintain their fascination, smaller asteroids present a more immediate threat, particularly given our society’s reliance on space-based technology. An impact from one of these smaller objects may not result in direct human casualties, but the consequences on our communications and navigation systems could be significant. This shift in focus highlights the evolving nature of planetary defense: it’s no longer just about safeguarding against extinction events but also about protecting our technological infrastructure.
The Importance of Advanced Observations
The role of telescopes such as the JWST cannot be understated in this context. As Assistant Professor Richard Teague elaborates, we are entering an era of extensive sky surveys that produce vast amounts of data. MIT is working on optimizing the analysis of this data to quickly identify and follow up on potential threats. The challenge arises with the smaller asteroids, as they are especially difficult to detect from ground-based telescopes due to their size. This makes space observatories like the JWST an integral asset in our planetary defense efforts.
Teague mentions the ambitious initiatives underway to develop a systematic approach to this new challenge—from detection to risk assessment to mitigation. MIT’s unique combination of experts in both astronomy and engineering puts it in an advantageous position to tackle these problems effectively.
The Upcoming “Asteroid Revolution”
Researcher Saverio Cambioni describes a forthcoming “asteroid revolution,” propelled not only by the JWST but also by the imminent Vera Rubin Observatory in Chile. This new facility aims to increase the detection rate of small space objects dramatically, potentially by a factor of ten. However, Cambioni cautions that detection is merely the first step; much work remains in characterizing these objects. MIT’s capabilities through observatories like the Wallace and Haystack will be crucial in bridging the gap between discovery and detailed analysis.
Engaging the Next Generation
One of the most exciting aspects of MIT’s efforts in planetary defense is its engagement with students. De Wit emphasizes the importance of involving the next generation of scientists in this vital work. MIT has designed courses and labs that allow undergraduate students to actively participate in observations and data analysis, fostering a new wave of astronomers equipped to carry this crucial work into the future.
Through these initiatives, students are not just spectators; they are integral contributors to ongoing research that holds significance for the safety of our planet. The combination of cutting-edge research and active student involvement creates a rich educational environment that empowers the new generation to approach planetary defense with both knowledge and passion.
A Collective Future in Space Awareness
As our understanding of asteroids deepens and our technology advances, the collective responsibility of planetary defense will only grow. The collaborative efforts at institutions like MIT highlight how interdisciplinary initiatives can effectively confront challenges that may not only be about our planet’s survival but also about the integrity of our way of life in an increasingly interconnected, space-dependent world. The journey in planetary defense is just beginning, and the contributions being made by researchers today will undoubtedly shape the framework for future endeavors.

NYC Schools Implement New Policy Banning AI Use for Students Through 8th Grade
New York City Schools Enact Strict Technology Policy
In an unprecedented move, nearly 600,000 public school students in New York City will soon face stringent restrictions on the use of artificial intelligence (AI) in the classroom. This policy, set to be unveiled by Mayor Zohran Mamdani and Schools Chancellor Kamar Samuels, aims to address growing concerns about the implications of technology in education as the new school year approaches.
Restrictions on AI for Younger Students
Under the new policy, generative AI tools—including chatbots, AI tutors, and instructional programs—will be completely prohibited for all students up to and including eighth grade. High school students will also face limitations, with access granted only under “restricted” conditions. This initiative marks a significant departure from policies in other school systems, positioning New York City as a leader in limiting AI’s role in early education.
Screen Time Limits for Young Learners
In addition to banning AI tools, officials are implementing strict limits on screen time for younger students. Children in preschool through second grade will not be allowed individual learning devices during class, while students in third to fifth grades will face a daily maximum of 30 minutes. Middle schoolers won’t be able to use devices for more than 45 minutes each day. This decision reflects a broader concern about the potential negative impacts of excessive screen exposure on children’s development.
Context and Rationale Behind the Policy
As the largest school system in the nation approaches the start of the school year on September 10, the announcement signifies a dramatic shift in educational technology policy. City leaders have been under pressure from parents, educators, and lawmakers who have voiced apprehensions about the integration of AI in learning environments.
Teacher Use of AI: A Different Story
While the restrictions are severe for students, the policy allows teachers to utilize approved AI tools for specific administrative and instructional purposes. These include lesson planning and transforming materials for diverse learning needs. However, the use of AI in grading, monitoring student behavior, counseling during crises, and developing individualized education plans remains strictly off-limits.
Voices of Concern: Parents and Educators
The push for this restrictive policy has been fueled by escalating anxieties among parents. Advocacy groups have called for a moratorium on AI use in schools, citing the need for safeguards to protect students from potentially harmful consequences. UFT President Michael Mulgrew has noted that many parents fear the unknowns associated with AI, emphasizing their protective instincts toward their children.
Mulgrew described AI as “a very dangerous thing,” urging schools to avoid implementing new technologies that haven’t been thoroughly vetted. This apprehension highlights the ongoing conversation about ensuring educational tools genuinely enhance learning rather than hinder it.
Critiques of AI in Education
Supporters of the restrictions argue that many AI-driven educational programs fail to provide substantial academic value. Critics contend that these resources often resemble video games, inadvertently encouraging students to avoid traditional, critical thinking methods. This viewpoint echoes prior concerns that led to New York City’s cellphone ban, which aimed to diminish distractions and enhance student engagement.
The Mayor’s Perspective
Mayor Mamdani asserted that the tech industry may promote AI in early education as both inevitable and essential. However, he and other officials are taking a more cautious approach, pushing back against the narrative that integrating AI into early education is a must-have.
Unveiling of the Policy
The formal announcement of these significant changes is scheduled for 10:30 a.m. at the Brooklyn STEAM Center in the Brooklyn Navy Yard. This event promises to set the stage for New York City’s educational landscape as it grapples with the balance of technological advancements and children’s developmental needs.

CR Extends Cybersecurity Information Sharing Law Until December
Cybersecurity Information Sharing Act: A Continuing Debate
In the complex landscape of cybersecurity, legislative measures like the Cybersecurity Information Sharing Act (CISA) of 2015 hold significant weight. Currently, Congress faces heightened urgency regarding the reauthorization of CISA, as concerns grow over cyber threats to critical infrastructure.
A Temporary Solution
Recently, Congress opted for a temporary solution by passing a continuing resolution that extends CISA 2015 through the upcoming stopgap funding period into early December. The Senate has already approved this measure, which now awaits President Donald Trump’s signature. However, the frequent short-term extensions have only intensified calls from industry leaders for a more permanent resolution.
Growing Concerns Amid Cyber Attacks
The climate of cybersecurity is shifting rapidly, fueled by advancements in artificial intelligence and a surge in cyber incidents targeting essential services such as water and wastewater systems. The urgency for a long-term reauthorization is palpable, as recent attacks have highlighted vulnerabilities that were previously underestimated.
The Role of CISA 2015
CISA is designed to provide essential privacy and liability protections, encouraging companies to share critical data about cyber threats and vulnerabilities with government agencies and each other. This collaborative framework is vital for identifying and mitigating widespread cyber threats effectively. Despite its importance, CISA has experienced lapses; it briefly expired during last fall’s government shutdown and faced uncertainties earlier this year.
Calls for a Robust Solution
Industry groups are increasingly vocal about the need for comprehensive reauthorization. Leaders from the Operational Technology Cybersecurity Coalition (OTCC) have pressured lawmakers, emphasizing that CISA’s reauthorization is crucial for preventing large-scale cyber campaigns. Tatyana Bolton, OTCC Executive Director, pointed out that the data shared under CISA allows for timely warnings to potential victims before attacks occur.
Bolton further stressed the importance of moving beyond temporary fixes, saying, “We can no longer keep doing minor extensions of CISA 2015. We must have long-term authority to operationalize actionable, timely, and relevant information.”
Legislators’ Concerns
Despite industry pressures, not all lawmakers are on board with a straightforward reauthorization. Senate Homeland Security and Governmental Affairs Committee Chairman Rand Paul (R-Ky.) has emerged as a significant roadblock. He has indicated that any reauthorization must address free speech concerns, introducing an additional layer of complexity to the negotiations.
Industry Perspectives
Industry associations have echoed the OTCC’s sentiments. In a letter advocating for a continued extension, they highlighted the necessity of government-industry collaboration to tackle evolving cybersecurity risks, particularly those associated with AI systems. The recent launch of the Treasury Department’s AI cybersecurity clearinghouse, “Gold Eagle,” depends heavily on the protections offered by CISA 2015.
The associations warned that a lapse in CISA would undermine not just ongoing information-sharing practices but also the foundational efforts of the Gold Eagle Initiative, which aims to expedite the detection and remediation of vulnerabilities in collaboration with key stakeholders.
Extending Cybersecurity Frameworks
In addition to CISA 2015, the recent stopgap funding bill also extends other critical cybersecurity measures, including the Federal Cybersecurity Enhancement Act and the Technology Modernization Fund, providing a temporary safety net as discussions continue.
The challenges surrounding CISA 2015 underscore the delicate balance lawmakers must strike between cybersecurity interests and broader legislative concerns. As debates continue, the focus remains on finding a sustainable path forward that will adequately address the growing array of cyber threats facing the nation.
