Hi everyone,
finally we can talk more about the next TU satellite CyBEEsat / TUBSAT-33 and its launch soon on the second Spectrum rocket of Isar Aerospace (First launch recap: Mission Going Full Spectrum). I hijacked this thread as all the payloads luckily were moved to the second launch. More information about the launch can be found on the website of Isar Aerospace: Isar Aerospace - Mission-2
For CyBEEsat I already put the information into the SatNOGS DB a while ago: SatNOGS DB - CyBEEsat. From the website: SpaceTeamSat1 from TU Wien Space Team, CyBEEsat from us and FRAMSat-1 from NTNU are still on the rocket in the first container and TRISAT-S in the second container, while MSAE-OTTER and the TOM satellites are not a part of this launch anymore. According to the website Let It Go from Dcubed and Platform 6 from EnduroSat are added to the launch, but I am not sure in which container or how big they are.
I will update the post as soon as we have a TLE for tracking.
The current launch time is 2026-01-21 20:00:00 (UTC) with a launch window of 15 minutes. @fredy if you need more information for the launch please let me know.
Lets keep our fingers crossed for a successful second launch
Here are my notes so far (if anyone else likes to see everything in one place for these multi-sat launches)
ISAR Spectrum - Andøya
The current launch time is 2026-01-21 20:00:00 (UTC) with a launch window of 15 minutes.

Let_It_Go
Let It Go is only an experiment according to ISAR and will remain on the upper stage
Updated launch time: 2026-01-21 20:06:00 UTC
Separation of satellites starts at: +4249 s → 2026-01-21T21:16:49 UTC
End of Radio Silence: +15 min → 2026-01-21T36:49 UTC
Stations in western Europe will likely be the first to be able to receive the satellites.
I’ve updated the first post with the satellites and the frequencies. For Let-it-go payload I haven’t found any frequency (not sure if transmits), however the ISAR rocket is expected to transmit in S-band 2200-2290 MHz, maybe this includes any transmission from Let-it-go.
TLE based on the preliminary TLE provided in the previous post:
@julianharbeck have in mind that I’ve archived the previous entry for CyBEEsat which was made for the previous launch and added a new one, so the temporary NORAD ID has been changed.
Satellites will be available for scheduling in Network near the launch time and I’m going to schedule stations for the first days after launch. Good luck to all the teams!
Following the launch attempt on Wednesday, 21 January, which was scrubbed to address an issue with a pressurization valve, we are taking additional time to complete targeted checks and preparations before the next launch attempt. More updates to follow.
