A current critique by Harvard Professor Avi Loeb, printed on Medium, has sparked dialogue relating to the priorities of the Asteroid Terrestrial-impact Final Alert System (ATLAS) mission. Loeb’s article particularly questions ATLAS’s observational technique, arguing that its present focus could inadvertently overlook objects getting into Earth’s ambiance, a perspective he frames as “ignoring Earth.” This commentary brings into focus a broader debate inside the astronomical group about planetary protection methods and the great monitoring of cosmic phenomena.
Background: Planetary Protection and Observational Techniques
The crucial to detect and observe Close to-Earth Objects (NEOs) stems from the catastrophic potential of cosmic impacts, a actuality underscored by historic occasions just like the Chicxulub impression and the Tunguska occasion. International efforts to ascertain sturdy planetary protection mechanisms gained important momentum within the late twentieth and early twenty first centuries, pushed by a rising understanding of asteroid dynamics and the developments in astronomical remark applied sciences. The Okay-Pg extinction occasion, attributed to an enormous asteroid impression roughly 66 million years in the past, serves as a stark geological reminder of Earth’s vulnerability to extraterrestrial threats. This realization catalyzed worldwide collaboration and the event of devoted asteroid survey packages.
Previous to the formal institution of complete surveys, sporadic efforts by skilled and beginner astronomers offered preliminary insights into the NEO inhabitants. Nonetheless, the necessity for systematic, wide-field searches grew to become evident as computational fashions started to foretell the sheer variety of doubtlessly hazardous objects. Early initiatives, usually beneath the umbrella of NASA’s Spaceguard Survey, aimed to establish 90% of NEOs bigger than one kilometer in diameter, a purpose largely achieved by the early 2000s. This success paved the best way for extra bold targets, together with the detection of smaller, but nonetheless regionally devastating, objects.
The Genesis and Evolution of ATLAS
The Asteroid Terrestrial-impact Final Alert System (ATLAS) was conceived as a essential element of this evolving planetary protection structure. Initiated in 2013 with funding primarily from NASA, ATLAS distinguished itself from different survey telescopes by specializing in a speedy, wide-field scan of the sky, designed to detect asteroids *days to weeks* earlier than a possible Earth impression. This “final alert” functionality is essential for offering civil protection authorities with very important lead time for evacuation or mitigation efforts, even for objects too small to be detected by earlier, much less delicate surveys.
The mission’s design philosophy centered on a community of comparatively small, however extremely automated and agile telescopes. The preliminary ATLAS-1 telescope grew to become operational in Hawaii in 2015, adopted by ATLAS-2 in 2017, additionally situated in Hawaii. These observatories leverage clear skies and strategic geographical positions to maximise sky protection. Every ATLAS unit consists of a 0.5-meter (20-inch) aperture telescope outfitted with a 100-megapixel CCD digicam, permitting it to picture an unlimited space of the sky in a single publicity. The system’s power lies not within the depth of its observations, however in its skill to repeatedly scan your entire observable night time sky a number of occasions per night time, detecting transferring objects in opposition to the background of stationary stars.
The success of the preliminary Hawaiian websites spurred growth. In 2022, ATLAS-South Africa (ATLAS-SA) grew to become operational close to Sutherland, South Africa, extending the system’s protection to the Southern Hemisphere. This was adopted by ATLAS-Chile (ATLAS-CH) in 2023, situated close to San Pedro de Atacama, Chile. This international distribution is important for making certain steady sky monitoring, mitigating the impression of hostile climate at a single website, and offering parallax measurements essential for refining asteroid orbits. The distributed community additionally enhances the system’s skill to detect objects approaching from the sunward route, a infamous blind spot for ground-based telescopes.
ATLAS’s main mission has been remarkably profitable, detecting a whole bunch of 1000’s of asteroids, together with a number of dozen which have come inside a lunar distance of Earth. It has additionally found quite a few comets and supernovae, demonstrating its versatility as an astronomical survey instrument. Its knowledge feeds into the Minor Planet Heart (MPC), a global clearinghouse for asteroid and comet observations, contributing to international efforts to characterize the NEO inhabitants.
Avi Loeb and the Galileo Undertaking
Professor Avi Loeb, a theoretical physicist at Harvard College, has grow to be a distinguished determine in discussions surrounding extraterrestrial phenomena. Identified for his work on black holes, the early universe, and exoplanets, Loeb garnered important public consideration together with his controversial speculation relating to ‘Oumuamua, the primary interstellar object detected passing by means of our photo voltaic system in 2017. Loeb recommended that ‘Oumuamua’s anomalous acceleration and strange form might be indicative of a synthetic origin, a declare that sparked appreciable debate inside the scientific group.
This line of inquiry led Loeb to ascertain the Galileo Undertaking in 2021. The mission’s said purpose is to conduct a scientific, clear, and scientific seek for extraterrestrial technological signatures and to establish the character of Unidentified Anomalous Phenomena (UAPs), previously referred to as Unidentified Flying Objects (UFOs). The Galileo Undertaking emphasizes the usage of state-of-the-art observational gear, together with telescopes, cameras, and sensors, to gather high-quality knowledge on UAPs and interstellar objects. It represents a departure from conventional astronomical surveys by particularly concentrating on phenomena that is likely to be indicative of non-terrestrial know-how.
Loeb’s work on ‘Oumuamua and the Galileo Undertaking underscores his broader philosophical stance: that science needs to be open to exploring unconventional hypotheses, particularly when confronted with anomalous knowledge. His critique of ATLAS, subsequently, emerges from this attitude, suggesting that present observational paradigms is likely to be too narrowly centered, doubtlessly lacking essential knowledge factors associated to things that might pose totally different, or much more speedy, varieties of threats.
Historic Precedents for Earth-Centered Observations
The idea of “Earth-focused” remark shouldn’t be new. Meteor bathe observations, bolide detection networks, and atmospheric analysis have lengthy geared toward understanding phenomena occurring inside or instantly interacting with Earth’s ambiance. Initiatives like the worldwide community of all-sky cameras for meteor research, or devoted observatories monitoring re-entering house particles, exemplify this focus. The Chelyabinsk meteor occasion in 2013, which brought on important injury and accidents in Russia, highlighted the significance of detecting and characterizing atmospheric entry occasions, even for objects too small to be recognized by typical asteroid surveys previous to impression. This occasion demonstrated that objects of tens of meters in dimension, whereas not planet-killers, can nonetheless pose substantial regional dangers and that their entry into the ambiance provides distinctive scientific alternatives.
The scientific worth of learning atmospheric entry occasions extends past mere hazard evaluation. Analyzing the composition and trajectory of meteoroids supplies invaluable insights into the early photo voltaic system, asteroid belt dynamics, and even the potential for delivering natural molecules to Earth. Due to this fact, a system that might present early warning and even real-time monitoring of such objects, even when they don’t seem to be “passing by” Earth however quite “getting into” it, might considerably improve each planetary protection and elementary scientific understanding.
Key Developments: The “Ignores Earth” Critique
Avi Loeb’s critique, articulated in his Medium article, particularly targets what he perceives as a strategic oversight within the ATLAS mission’s operational philosophy. The core of his argument facilities on the excellence between objects that *go by* Earth and those who *enter* Earth’s ambiance. He contends that whereas ATLAS excels at figuring out objects which may impression Earth sooner or later, its design and operational parameters will not be optimized for detecting and monitoring objects which are already on an atmospheric entry trajectory or have lately entered.
Loeb’s Particular Arguments
Loeb’s “Ignores Earth” declare is multifaceted. He argues that ATLAS, by design, prioritizes the detection of transferring objects in opposition to a stellar background, figuring out their orbital paths *earlier than* they pose an imminent menace. This strategy is superb for long-term planetary protection, permitting for potential mitigation methods or superior warnings. Nonetheless, Loeb factors out that when an object is already on a collision course with Earth’s ambiance, its obvious movement relative to the background stars adjustments considerably, and its detection necessities shift.
He posits that ATLAS’s present configuration, significantly its subject of view and cadence, won’t be ideally fitted to objects which are both very small and fast-moving, or these which are already present process atmospheric ablation. Such objects, particularly if they’re coming from a route that locations them within the solar’s glare or are solely detectable at very low altitudes, might doubtlessly be missed or poorly characterised by a system primarily designed for distant detection.
Loeb attracts a parallel with the Chelyabinsk occasion, the place a roughly 20-meter asteroid entered the ambiance with just about no warning from ground-based astronomical surveys. He means that whereas ATLAS goals to forestall such surprises, its present operational parameters would possibly nonetheless depart a niche for related, or much more uncommon, atmospheric entry occasions. His concern shouldn’t be that ATLAS is failing its said mission, however quite that its mission, as at the moment outlined, is incomplete from a complete planetary protection perspective.
Moreover, Loeb’s critique extends to the potential for interstellar objects. Whereas ATLAS has detected interstellar objects like 2I/Borisov, its main focus stays on photo voltaic system objects. Loeb argues that if an interstellar object have been to enter Earth’s ambiance, particularly one with uncommon properties (as he controversially recommended for ‘Oumuamua), the present ATLAS system won’t present the mandatory knowledge for an intensive scientific investigation of its origin or nature. He advocates for a system that may not solely detect objects *approaching* Earth but additionally characterize those who *work together* with Earth’s speedy surroundings.
Reactions from the Planetary Protection Neighborhood
The planetary protection group’s response to Loeb’s particular critique has been diversified, although largely pragmatic. Many inside the subject acknowledge the theoretical validity of a few of Loeb’s factors relating to the challenges of detecting very small, fast-moving objects or these on speedy atmospheric entry trajectories.

For such objects, ATLAS performs exceptionally properly.
Proponents of ATLAS and related survey packages usually spotlight the sensible constraints of telescope design and funding. Constructing a system that may concurrently excel at wide-field, long-range detection *and* extremely localized, speedy atmospheric entry monitoring presents important engineering and monetary challenges. Completely different devices are sometimes optimized for various observational niches. As an example, devoted bolide cameras and atmospheric monitoring methods are already in place, although maybe not as globally coordinated or as delicate as Loeb would possibly envision.
Some consultants recommend that Loeb’s critique, whereas legitimate in figuring out a possible hole, misrepresents ATLAS’s supposed scope. They argue that ATLAS is a vital *early warning* system, not an *atmospheric entry monitoring* system. The latter sometimes includes several types of sensors, usually trying *down* from house or *up* from a dense community on the bottom, quite than scanning your entire sky for distant transferring objects. Nonetheless, the dialogue prompted by Loeb’s article has undeniably contributed to a broader dialog in regards to the completeness of world planetary protection methods.

Rubin Observatory (previously LSST), anticipated to attain full operations within the mid-2020s, will present unprecedented sky protection and depth, considerably enhancing the detection of each photo voltaic system NEOs and potential interstellar guests. Whereas circuitously addressing atmospheric entry, these bigger surveys will contribute to a extra complete understanding of the thing inhabitants which may ultimately work together with Earth.
Moreover, developments in atmospheric science and sensor know-how are making it simpler to detect and characterize bolide occasions. Floor-based infrasound arrays, satellite-based optical sensors (like these operated by the U.S. authorities for nuclear check monitoring), and devoted meteor cameras contribute to a rising international community able to recording atmospheric entries. The problem, as Loeb implies, is integrating these disparate knowledge sources right into a cohesive, real-time warning and characterization system.
The Galileo Undertaking itself represents a direct response to a few of these perceived gaps. By deploying its personal community of telescopes and sensors particularly designed to search for anomalous atmospheric phenomena and interstellar objects, Loeb’s group is trying to construct the very observational capabilities he suggests are missing. Their efforts to seize high-resolution knowledge on UAPs and analyze them scientifically are a sensible manifestation of his critique, aiming to fill the void he identifies in current planetary protection and astronomical survey architectures. The mission’s preliminary deployments, similar to a ground-based observatory at Harvard Faculty Observatory, purpose to gather multispectral knowledge on unexplained aerial phenomena.
