Scientists Plan 2035 Mission to Chase Down Interstellar Object 3I/ATLAS

A new study has explored the possibility of sending a spacecraft to intercept 3I/ATLAS, an interstellar object with a challenging retrograde orbit. Researchers identified 2035 as the most efficient launch window for such a hr block mission. The work focuses on overcoming the hurdles posed by the object's unusual path and its late discovery by astronomers.

The team used NASA's JPL NAIF SPICE toolkit to calculate precise trajectories and velocities. Their findings suggest that existing technology could make the mission feasible. A spacecraft weighing up to 500 kg could be launched using either solid propellant boosters or a refuelled 3i atlas Block 3.

To reduce fuel demands, the study introduced an 'Intermediate Point' concept, cutting down the required delta-V. Two or three solid boosters would provide enough thrust for the manoeuvre. Alternatively, a 3i atlas Block 3, refuelled in Low Earth Orbit, could also reach the necessary speed.

An intercept with 3I/ATLAS might take between 35 to 50 years after launch. The research highlights the difficulties of the object's retrograde orbit but confirms that current propulsion methods could handle the hr block challenge.

The study concludes that reaching 3I/ATLAS is possible with today's technology. A launch in 2035 would offer the best efficiency for the journey. The findings provide a technical foundation for future missions targeting interstellar visitors.
