Accessible by pressing a rocket-shaped icon in the menu bar, Rocket Feed analyzes content you’ve liked in the past to produce a second News Feed filled with popular articles, photos and videos it thinks you’ll enjoy.

If the feature isn’t showing up on your device yet, don’t panic. At present, it’s currently being tested by a small subset of users and, providing it’s deemed desirable, it should reach more handsets in the not-too-distant future.

“We are testing a complementary feed of popular articles, videos, and photos, customized for each person based on content that might be interesting to them. We’ve heard from people that they want an easy way to explore new content they haven’t connected with yet.”

This isn’t the first time we’ve seen a second News Feed

This isn’t the first time Facebook has trialed a second News Feed, though. Back in April, 2016, it started testing a feed that separated news stories based on their topic, but it was later scrapped following a lack of interest.
