Mars helicopter flies again; encounters radio interference on 17th flight
"As Ingenuity began to descend, the line of sight between the rover and helicopter antennas [became] obstructed/shadowed" by the hilly terrain, Teddy Tzanetos, the Mars program lead, wrote in a blog post Tuesday evening.

interesting read. thanks.

That's not what I would call radio interference, usually I take that to mean interference by other radio signals, which is why I read the article, but ¯\_(ツ)_/¯

Thanks for sharing.  Quite the article.
