Clipper & Hera To Fly Through 3I/Atlas' Ion Tail ~ IFL Science ~ 17 October 2025

IFL Science

Well, if 3I/Atlas decides to grow an Ion tail by then, that is. 

A short but informative report from IFL Science, please read it here. The following is an excerpt:

According to a new paper, both spacecraft will be aligned in such a way that they could be entering the comet’s ion tail in the coming weeks. It is an excellent time to do so; the interstellar comet is not going to get very close to the Sun (203 million kilometers; 126 million miles), but that minimum distance will also mark a peak in activity. It is happening on October 29, and both spacecraft will be within the possible location of the ion tail.

Namarie! 💛
