What's Happening?
Harvard astrophysicist Avi Loeb is advocating for NASA to use the Juno spacecraft to study an interstellar object, 3I/ATLAS, discovered on July 1. The object, traveling at 137,000 mph, is in a hyperbolic orbit and will pass close to Mars and Jupiter. Loeb proposes using Juno's remaining propellant to position the spacecraft for a close encounter with 3I/ATLAS, providing a unique opportunity to study an interstellar object up close. NASA is considering adding 3I/ATLAS observations to the schedules of the Hubble and James Webb space telescopes.

Why It's Important?
Studying interstellar objects like 3I/ATLAS offers valuable insights into the formation of planetary systems and the chemical elements present in distant star systems. A close encounter with Juno could provide unprecedented data on the object's composition and behavior, enhancing our understanding of interstellar phenomena. This research could inform future missions and contribute to the broader field of astrophysics.
What's Next?
NASA is exploring options for observing 3I/ATLAS with existing telescopes, while Loeb continues to advocate for using Juno for a close encounter. The object will be visible to ground-based telescopes through September, providing opportunities for further study. The Vera C. Rubin Observatory is expected to join the hunt for interstellar objects later this year.
Beyond the Headlines
The proposal to use Juno for studying 3I/ATLAS highlights the potential for repurposing existing spacecraft for new scientific missions. It underscores the importance of flexibility and innovation in space exploration, as well as the need for continued investment in research and technology to study interstellar phenomena.
