It looks like Firefly Alpha is finally going to launch with the window September 03, 2021 01:00-05:00 UTC at SLC-2, Vandenberg Space Force Base, USA.
The launch will be live-streamed by Everyday Astronaut: FLTA001 DREAM | Alpha | Everyday Astronaut | Prelaunch Preview
Lots of interesting CubeSats and PocketQubes to be deployed including the Teacher’s In Space Serenity 3U CubeSat!
Here’s a list of payloads: Firefly
I’m sure others here are involved in the other sats, but I’m most familiar with Serenity, which will have a transmitter at 437.1 MHz 4k8 FM with AX25. I believe it will beacon for the first 72 hours, then after that will send status packets when it receives command packets from any ham on the same frequency. There’s some details here: Serenity | Teachers In Space, Inc.
So it is probably time to get these sats into the database to be ready for launch!
