INITIAL POST:

Well, this just popped up on YouTube:

… and from this URL:

… I see some details:


The NRCSD-26 mission, sponsored by ISS National Lab, includes five CubeSats carrying projects designed by students at universities in Canada. In addition to their scientific objectives, these projects provide hands-on experience and promote interest in science, technology, engineering, and mathematics (STEM) studies and careers. During the week, crew members installed hardware to set up for deployment of these satellites:

  • Nanoracks-RADSAT-SK tests a radiation detection system and radiation protection from a purified form of melanin, a natural pigment found in many organisms.
  • Nanoracks-SC-ODIN captures data on dust in storms in Argentina and Namibia and monitors radiation received over time inside and outside of the satellite.
  • Nanoracks-ESSENCE monitors solar storms, arctic ice, permafrost thaw, and forests in the Canadian Arctic region and demonstrates recovery of attitude if one of a satellite’s actuators fails.
  • Nanoracks-Iris observes weathering of geological samples from direct solar and background cosmic radiation and determines whether changes are visually detectable over short time scales.
  • Nanoracks-Ukpik-1 captures 360-degree images and video of Northern Canada with a virtual reality (VR) camera and facilitates educational outreach and public engagement in Ontario and Nunavut.

We are also flying Moonlighter, the world’s first ever hacking sandbox in space! Moonlighter is a 3U CubeSat built by The Aerospace Corporation, purposely designed to advance the understanding of cybersecurity as it applies to space systems. The CubeSat will be used at the DEFCON conference by the Air Force/Space Force to engage cybersecurity professionals by challenging them to hack a real-life satellite.

Thanks all for the information!

Satellites and their transmitters added in DB by @ENSFNM.

I’ve set them to follow ISS for now, I’ve also updated the first post to gather there all the information.

Might as well delete this one SpaceX F9: CRS-28 Dragon 2: KSC : 5 June 2023. Was wondering how long it would be before they were deployed from ISS.

Looks like 6 cubesats lifted off to ISS on SpaceX CRS-28 for a later deployment at some point soon after. Five cubesats from Canada – RADSAT(-SK) IARU, UKPIK IARU, SC-ODIN IARU, ESSENCE IARU requested, Iris info and US Air Force Research Lab’s Moonlighter ‘hack-a-sat’ challenge. I didn’t see any of these in DB in in the forum, apologies if they are documented somewhere and I missed it. No real mention of the cubesats themselves for this launch on the nasaspaceflight forum like we’d normally see…

I’ve received an email from William VE4VR, an amateur affiliated with the IRIS Cubesat team. I informed him that unfortunately due to the lack of IARU coordination, we have a policy of limiting tracking to that needed for Space Situational Awareness. I’ve also pointed him to this thread and to the SatNOGS chat room on Matrix.

He provided me with a little more info:

Satellite = University of Manitoba, Iris CubeSat

Receive = 436.250

Mode = 9600 (Tested with KPC-9612)

Data = KISS Mode + CSP Packets

If I recall correctly, this is also an AX100 radio operating in Mode 5 (ASM+GOLAY), so that should be FSK 9600.

I’ve scheduled a couple of observations for the next 48 hours. To station owners have in mind when you schedule that we use ISS TLE set, so leave some passes for ISS scheduling too. :wink:

The KPC-9612 is a Kantronics 9k6 AX25 G3RUH packet modem.
Lets also look for non AX100 frames.

For gr-satellites users, this yml file should be able to decode both.

Looking at this link, it does seem to be using a GOMspace radio.

As of 20:00 UTC, not a single ‘green’ SatNogs observation from any of these objects.

Seems like at least one would have been heard this long after deployment. Will watch for one or more of them when the U.S. gets a pass late tonight!

Still no signal from any of the Satellites until now. It is interesting that in the previous NRCSD deployment 2 from 6 were alive for less than a day and then they also went silent.

I’m starting wondering if something goes wrong with these kind of deployments or it is just random.

Still nothing in Network observations.
