GPS satellites orbiting Earth

October 12, 2024

We rely on GPS satellites to help us figure out exactly where we are. How many of them are orbiting Earth right now? Is it … A.) Four, B.) 15, C.) 24 or D.) 31?

The answer: D.) 31. The GPS satellites are positioned along six different orbital planes approximately 12,550 miles above the earth. Each orbits our planet twice a day. While only four satellites are needed to calculate a precise location, at least 24 are required to cover the planet. The extra seven are backups.

Dolphins 'smile' to signal play

New research shows bottlenose dolphins “smile” at each other to signal playtime. In science speak, it’s a “prolonged open-mouth expression,” and it only happens when their friends are in view — never in other contexts. The video is adorable.

Green Day is going all out: To celebrate their “Dookie” album’s 30th anniversary, the California punk rock band has released “demastered” versions of their songs played on some hilariously inconvenient formats, including “Pulling Teeth” on a toothbrush, “Chump” on a Teddy Ruxpin and “Welcome to Paradise” on a Game Boy cartridge. The promo vid is amazing.

'Juror #2' trailer (2024) feat. Nicholas Hoult, Clint Eastwood

Clint Eastwood’s 94 and still directing. The trailer just dropped for his newest film, “Juror #2.” It’s a courtroom thriller. (I know, shocker.) Looks good! My goal is to be like Clint when I’m 94!

10K Japanese character vs. running man — Amber Reeves | Komando.com, Â© Krupal Ghori | Dreamstime.com

No one knows for sure, but 10,000 steps per day might be the suggested standard based on the Japanese character for 10,000. Looks like someone running or walking to me.

This is me in Tennessee. I was about 10 when I did a full circle over the bar because the boys dared me. That’s how I lost my front tooth, so the one you see is fake!

I made this using ChatGPT. For my next piece? I’m drawing a blank.
