I was watching the Canadian Space Agencies BROLL video of the CASSIOPE satellite due to launch in a few days and noticed a neat antenna. The video link below starts at the appropriate point in the video (feel free to watch the whole video too). For what looks like it is essentially steel tape measure metal... that's quite an intense antenna and deployment! I'm used to seeing these on cubesats and other small satellites but this is very neat to see too.

It looks like it's the descendant of what was used on Canada's first satellite, Alouette-1:

Many years ago, there was a documentary about the early days of Canada's satellite program and I remember this was mentioned. Unfortunately, I don't remember what the name was.

Regarding Canada's Space Program, did you know that Canada's oldie satellite Allouette-2 is back to live???, or at least its transmitters.....
While I was monitoring the 136-138 satellite sub-band a couple of months ago with a RTL2832U based cheap SDR dongle I founded weird doppler shifted signals not matching any known transmitting satellite. After reporting it on the HearSat mailing list and posterior confirmation from Mike Kenny in Australia the best match was Canadian old satellite Allouete-2 launched in 1965.
It is amazing how solar panels, antennas and transmitters stages are functioning after 48 years!!! It can be heard on: 136.076 +- 2 KHz with high instability, strong. 136.589 with unmodulated sub-carriers, weak. 136.981 Continuos Wave.
All three transmitters are alive after many years. It seems that due to some unknown reason it started to transmit again. May be the very same UFO which un-plug the batteries from the AO-07 bus ran across that oldie historical satellite and push the "ON" button HI HI HI HI HI!!!
All the bests and 73,

Maybe there's hope for some of our other silent OSCARS, such as AO-51.

Nope, It was only announced on the HearSat mailing list and only few enthusiastics replied. On this world of new space probes with S band downlinks very few are interested in monitoring old birds which comes back to live spontaneously.
However the happiness and enjoy I felt after re-discover that old historical spacecraft is beyond compare.... It is like space archeology.... An U.S. ham re-discovered LES-1 several months ago and some media wrote a news report, but the original owner/builder of the satellite didn't reply to his e-mail....
About Allouette-2, the interesting was the international collaboration, Cuba and Australia are almost in opposites part of the world, but Mike Kenny and I still exchange information and collaboreted for confirm the re-discovery, and that my friend is the true ham spirit....

When the 50th anniversary of Alouette 1 came and went, there wasn't much on the news about it here in Canada or, at least, I didn't see much. I guess it wasn't as fancy as a Blackberry.

I've been listening to the archived recordings of The Space Show at:
and one point the host often makes is that space has been one realm in which different nations have largely co-operated and have generally remained peaceful.

I found a tracking URL for it:
http://n2yo.com/satellite/?s=25058
Apparently it re-entered on 1999-12-15 and NASA has nothing on it:
http://nssdc.gsfc.nasa.gov/nmc/masterCatalog.do?sc=1965-098L
Alouette-1, on the other hand, is still in orbit:
http://n2yo.com/satellite/?s=424
and here's what NASA has on it:

Now you've got me interested.....

Hi Bernhard and all,
I guess you are looking into the wrong catalogue number. Allouette-2 is 1965-098-A, not "L" which is what you looked for. I download its TLE regularly from Space-Track. NORAD Number is 01804.
The TLE I am sending you is from 4 days ago are still good, in a previous e-mail I sent the frequencies:
0 ALOUETTE 2 1 01804U 65098A 13267.80431926 .00000325 00000-0 11085-3 0 4491 2 01804 079.8011 254.0639 1347527 258.0698 086.6578 12.24267898109332
Mike Kenny has a nice page with old ages and historical 136-138 MHz band emitters. I don't remember the address, but you can Google it.
By the way, my apologize to the rest of the AMSAT-BB readers, as it is not a 100% ham sat topic....

I stand corrected. I gathered what I found before was information about Alouette 2's debris, which I assumed was referring to an inactive satellite. There's also an entry for 1965-098K, which is also debris.
The correct URLs for Alouette 2 would be:
http://n2yo.com/satellite/?s=1804 http://nssdc.gsfc.nasa.gov/nmc/masterCatalog.do?sc=1965-098A
There's more information on Alouette 2 at:
http://astronautix.com/craft/alouette.htm
Also, I found these links to be useful:
http://planet4589.org/space/space.html http://planet4589.org/space/log/launch.html http://planet4589.org/space/log/satcat.txt
By the way, your comments prompted me to look up the HearSat mailing list and I signed up for it earlier this evening. Thanks for the tip. Now I have another way to have fun with satellites!
Perhaps listening for old satellites might be a suitable topic for a Journal article.
