Could Aging NASA Spacecraft Capture Stunning Images of the Interstellar Comet Beyond the Sun? Astronomers Weigh In!

A recent study by Harvard astronomer Avi Loeb and his team proposes an intriguing idea: intercepting an interstellar comet named 3I/ATLAS. Discovered on July 1, 2025, this comet moves at a staggering speed—approximately double that of previous interstellar visitors like ‘Oumuamua and Comet Borisov. Its nucleus is about 5.6 kilometers (3.5 miles) across, making it significantly larger than the first two interstellar objects.

What makes 3I/ATLAS especially interesting is its potential origin. Scientists believe it might have traveled from a different region of our galaxy and could be much older than any known body in our Solar System. However, there’s a challenge: when the comet comes closest to the Sun, it will be positioned on the far side from Earth, making it tough to study.

In their paper, Loeb and his colleagues suggest using NASA’s Juno spacecraft to capture data as 3I/ATLAS makes a close flyby of Jupiter. They explain that Juno, which currently studies Jupiter, could be redirected for this unique opportunity. The spacecraft is equipped with a variety of instruments, including a near-infrared spectrometer and a visible light camera, capable of gathering detailed information about the comet.

To successfully intercept 3I/ATLAS, the team proposes an “Oberth Maneuver.” This powerful technique allows Juno to gain speed by dropping deep into Jupiter’s gravity well before firing its engines for additional thrust. They estimate a specific maneuver could shift Juno’s trajectory to intersect with 3I/ATLAS on March 14, 2026.

While exciting, this idea comes with challenges. NASA’s budget cuts and the current mission timeline for Juno—scheduled to end in September 2025—complicate matters. Additionally, the path of the comet may change as it approaches the Sun, adding uncertainty to the plan.

Interestingly, Loeb has also hinted that 3I/ATLAS could be more than just a comet. In previous discussions, he speculated that it might be an interstellar probe sent by an advanced civilization. He raised the idea of the “Dark Forest” hypothesis—a theory that suggests civilizations in the universe might preemptively attack others to protect their existence.

While such theories captivate imaginations, experts warn to approach them with caution. Most astronomers advocate for solid empirical evidence before jumping to conclusions about extraterrestrial life.

As celestial objects continue to enter our Solar System, the knowledge we gain from studying them is invaluable. Even if NASA doesn’t choose to redirect Juno for this comet, future missions will likely enhance our understanding of interstellar objects.
