Earlier this year, astronomers discovered a fascinating interstellar object called 3I/ATLAS. This remarkable visitor is moving fast through our solar system and marks only the third confirmed interstellar object we’ve observed. Thanks to improved technology, we’re now able to spot these unusual travelers more easily.
Researchers have been using powerful telescopes, like the Very Large Telescope in Chile and NASA’s Hubble Space Telescope, to study 3I/ATLAS. Harvard scientist Avi Loeb has even proposed using NASA’s Juno spacecraft to intercept this object’s path for a closer look. He sees the close approach of 3I/ATLAS to Jupiter as a unique chance for a thrilling exploration.
In a recent blog post, Loeb argued that if Juno changes its current orbit, it could catch up with 3I/ATLAS. He also received support from Representative Anna Paulina Luna, who urged NASA to assess Juno’s fuel and consider extending its mission. However, not everyone is on board with this idea.
Astronomy experts, like Penn State’s Jason Wright, have expressed skepticism. He pointed out that Juno doesn’t have enough fuel for a mission to 3I/ATLAS, and its main engine is malfunctioning. Wright’s comments reflect a broader caution in the scientific community regarding such ambitious plans.
While some scientists are doubtful, others think we shouldn’t rule out the possibility. Mark Burchell from the University of Kent suggests that Juno’s orbit could still provide valuable data, despite the challenges it faces. He noted that Juno has previously been exposed to significant radiation on its travels around Jupiter.
Intercepting a fast-moving interstellar object is tricky. According to a study from Michigan State University, a new mission would need to accelerate at 15 miles per second right from the beginning to catch 3I/ATLAS. Still, fragile spacecraft in the Mars vicinity might get a chance to make observations when 3I/ATLAS comes closest to the Sun.
Interestingly, the European Space Agency is also considering this opportunity. Their Jupiter Icy Moons Explorer (JUICE) might be able to capture data on 3I/ATLAS. However, changing the course of a spacecraft is more complicated than portrayed in movies.
Time is running short to act, and visiting 3I/ATLAS could be a formidable task. But for scientists, the prospect of getting close to an interstellar object is too intriguing to ignore. As we approach December, which is when the object will be closest to Earth, there’s a sense of urgency.
Getting up close could provide insights into the nature of interstellar objects, enriching our understanding of the universe. The excitement around 3I/ATLAS reflects humanity’s ongoing quest to explore beyond our own world.
