Engagement
Early reading. We have captured 3 original posts for this account, below the 8 we require before treating a median as settled. The numbers above describe what we have seen so far, not a finished profile of the account.
A typical post picks up 55 interactions against 1.0M followers, an engagement rate of 0.005%. Posts are seen about 8.9K times each, and 0.618% of those impressions turn into an interaction. That is about 0.853% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 0.1 posts a day over the last 30 days, though only 10% of days saw any activity at all. Most posts go out around 18:00 UTC, and Friday is the busiest day of the week. Of the 3 posts sampled, 100% carry an image or video. The account's strongest tracked post pulled 4.5K interactions, about 81x its own typical post. Only 3 original posts have been captured so far, fewer than the 8 posts we want behind a median before treating it as settled.

Posting timing
This account posts most often around 18:00 UTC, and Friday is its busiest day of the week. The bars below are the catalog-wide pattern, with this account's own busiest slot marked. They do not show how this account performs at each hour: we keep one aggregate per account, not one per hour, so that measurement does not exist in our data.

I am amazed by the sheer size of The Great Wall of China - stretching over 13,000 miles (21,196 km) and built across more than 2,000 years. I am grateful I had the opportunity to visit and experience a small section of it. https://t.co/KDCEu7TKpQ

#OTD 23 years ago, we experienced the unimaginable - the loss of Space Shuttle Columbia and its crew of 7 astronaut colleagues and friends. I still miss them terribly, not a day goes by that do not think about them. Was an honor to know each of them - a great group of heroes we should all try to emulate.

For real inspiration and hope you must see “Spacewoman” - a documentary about the amazing life of my friend and colleague Eileen Collins - the first woman to pilot the Space Shuttle and the first to command a Space Shuttle mission, she is a true American hero. I enjoyed catching up with Eileen and watching the movie this weekend. It is truly out of this world! @ECollinsSpace

It was a mini astronaut reunion last night, my dear friend and Space Shuttle Commander Scott "Scooter" Altman received the George C. Marshall Award in Ethical Leadership. It was great also seeing my colleagues Bob Behnken and Greg "Box" Johnson. Congratulations Scooter on this well deserved recognition.
