I'm ploting altitude of five CubeSats which were deployed from ISS.
The results is interesting. First deployment satellites are lower
altitude than laters. I guess this is related to initial velocity at
deployment.
First Deployment
deployment order: #1 WE WISH, #2 RAIKO
altitude: WE WISH < RAIKO
Second Deployment
deployment order: #1 TechEdSat, #2 F1, #3 FITSAT-1
altitude: TechEdSat < F1 < FITSAT-1
I'm also ploating ARISSat-1 on the same chart as its time line align
to the five CubeSats deployment date. The chart shows five CubeSats
have large decay rate than ARISSat-1.

I gave up on IRC's over a decade ago. The last batch I purchased via mail from the local post office. They always had a fit when I went to the counter, I held up the line while they stamped them. The last batch were stamped on the wrong side, when I took them back they, at first refused to refund my money or replace them, the clerk said once stamped on that side they were worth only one domestic airmail stamp. Got really bent out of shape when they told me some I had were out of date, they were carefully marked "No Expiration"
Used to buy at least one sheet of each commerative as it was released (starting in the late 50's). By the 80's they were releasing commeratives at a rate that made the European micro states look like pikers. Not long ago I decided to sell off a lot of them. Most of the offers were less than face value. So I have been using them for postage (now that sure doesn't help the post office out of its current problems).
In The late 1990's I stopped at Bill Plumb's booth at the Dayton Hamvention and purchased two of his stamps in an attempt to get two outstanding cards. Got both cards in a few weeks and have been using his stamps ever since, in most cases the country stamp was cheaper than an IRC.
Returns are over 90%

FITSAT-1 5.84 GHZ Downlink Received in USA
The FITSAT-1 CubeSat, developed by students at the Fukuoka Institute
of Technology (FIT) in Japan has a CW beacon on 437.250 MHz and a
data link on 437.445 MHz. There is also a 5.8 GHz data downlink and
an optical LED experiment that will flash Morse code planned to be
visible with the unaided eye.
FITSAT-1, also named NIWAKA was one of five cubesats launched on
July 21 and loaded aboard the ISS. These were integrated with the
J-SSOD small satellite deployer on the the Japanese Experiment Mod-
ule, also known as Kibo. They were deployed with the Kibo robotic
arm on October 4.
Shortly after deployment into orbit FITSAT-1 was heard with strong
signals on its 437 MHz downlinks. FITSAT CW transmits, "HI DE NIWAKA
JAPAN" with its telemetry data.
Mike Sequin, N1JEZ in Vermont reported success in copying the 5.8 GHz
downlink from NIWAKA. Mike wrote, "Success! I was able to detect NI-
WAKA. It was lower in frequency that I expected, but with the Funcube
[Dongle], it was easy to spot. The Doppler was huge! and I was moving
the dish almost continuous to try and keep up. The 5.84 GHz transmit-
ter seemed to come on very close to the set time. First detection was
at 12:24:21 UTC."
Mike posted two screen shots. In the first shot, you can see the sig-
nal on the left side Doppler shifting down. In the second, a close up
of one data burst with Doppler - about 3 seconds or so:

+ http://tinyurl.com/N1JEZ-Screen2
Mike's station used a 5.760 DEMI Transverter with a 144 MHz IF. That
Is why the HDSDR screen for the FUNcube Dongle is tuned to 224 MHz.
His antenna is a 2 foot dish is with a Directive Systems 5.76 G feed.
You can receive a FITSAT-1 QSL card by sending your signal report
and your postal address to: fitsat1 at hotmail.co.jp and also cc: to
tanaka at fit.ac.jp. A photo of the QSL card is shown at:
http://www.fit.ac.jp/~tanaka/fitsat.shtml (This web page will also
be updated with information about the status of the LED experiment."
HB9FFH has made a telemetry decoder for FITSAT-1, available at:
http://carpcomm.com/satellite/fitsat1
FITSAT students have also developed a similar program for windows:

FM Data 437.445 MHz,
High speed data 5840.00 MHz

Japan Schedules Launch of New Low Cost Epsilon Rocket
Japan is scheduled to launch its first Epsilon solid-fueled rocket next year,
deploying a planetary telescope in orbit while
demonstrating new low-cost rocket
assembly and control techniques, the Japanese space agency announced last week.
The Epsilon program is designed to cut in half the cost of Japanese small
satellite launches. Japan's M-5 rocket, which launched seven times before
retiring in 2006, cost $94 million per flight. Engineers designed the Epsilon
rocket with a simplified control system, and the vehicle's own computers will
autonomously monitor the status of its systems during a countdown. Only a
handful of engineers with laptop computers are required on the launch control
team, according to JAXA. The Epsilon is also
designed to launch after only seven
days of assembly on the launch pad, reducing labor and overhead costs.
The Yomiuri Shimbun newspaper reported last week the first launch of an Epsilon
rocket is scheduled for August or September of 2013.

FUNcube-1 CubeSat time-lapse video
A time-lapse video made in the ISIS clean-room showing the integration of the
AMSAT-UK amateur radio satellite FUNcube-1 has been released
FUNcube-1 is aiming to launch on a DNEPR rocket from Yasny with 17 other
satellites carrying amateur radio payloads in the first half of 2013.
FUNcube is a complete educational single CubeSat project with the goal of
enthusing and educating young people about radio, space, physics and
electronics. The target audience consists of
primary and secondary school pupils
and the satellite will feature a 145 MHz telemetry beacon that will provide a
strong signal for the pupils to receive.
FUNcube-1 also carries a 435 to 145 MHz linear transponder for SSB/CW
communications.
It is being designed and built by AMSAT-UK and AMSAT-NL in collaboration with
ISIS Innovative Solutions in Space BV.

ARISS Status - 5 November 2012
1. Successful ARISS Contacts Held
On Tuesday, October 30, South Florida Science Museum (SFSM) in West Palm Beach,
Florida welcomed county students to participate in an Amateur Radio on the
International Space Station (ARISS) contact with Akihiko Hoshide, KE5DNI aboard
the ISS. The West Palm Beach Amateur Radio Club, WPBARC, which maintains a ham
station within the museum, collaborated with area teachers to provide
educational content to students emphasizing NASA,
the ISS and amateur radio. The
club facilitated the radio connection with the ISS. During the contact,
approximately 90 students were present at the
radio station site and another 200
were in an adjacent room watching by CCTV. VIPs in attendance included Scott
Carpenter - one of the original seven astronauts. The contact was seen by
125,000-187,000 students. The event was broadcast over the air on the
Educational Networks channel 23, the PBS station's channel 42.4 (digital), and
on 2 local Comcast Cable channels, bringing the
estimated live audience to about
250,000 viewers. Others watched the live stream on the internet. Video is

The last time I bought some IRC's I was surprised to find later that
they had an expiration date. So I lost money on them. I would NOT be
stocking up on these unless you really expect to use them up.

Saw this story about the US Army's Space and Missile Defense Command (SMDC) in Alabama who've built a 3D printer.
http://www.bbc.co.uk/news/technology-20269645
I wondered if anyone had any up-to-date news on PrintSat that students at Montana Sate University were planing to make with a 3D printer ?
The BBC also report on the Interplanetary Internet (Disruption-Tolerant Networking protocol) trials that took place on the ISS, see

The ARRL Letter dated November 8th has an item
about the USPS proposing to discontinue the sale
of IRC's here in the United States. If you are
sending for a QSL card to many countries, the alternative
compensation, American dollar bills, are likely to be stolen by
a postal worker. Your card never makes it and you don't
get one back. IRC's can only be exchanged for stamps so the
likelihood of them being stolen is lessened.
IRC's are available at usps.com so there is no need to have
them stocked or ordered at a local post office. It costs
literally nothing to have them in the online store. If the
sale of IRC's is discontinued here in the US, you will have to
buy them from another country. IRC's must be exchanged for
postage by Universal Postal Union member countries but there
is no requirement that they be sold in member countries.
There is a link in the ARRL Letter that goes to a site where you
can file comments regarding the proposal. The URL is
http://www.regulations.gov/#!submitComment;D=USPS-2012-0101-0001
I did that and made the case for retaining them in the usps.com
store only. Please consider doing the same so we don't have to
buy them overseas.

It took working my up from desk clerk to supervisor to manager before I got someone at the Scottsdale Airpark PO who even knew what they were.
ThenI was told they don't carry them anymore.
I get mine online.
That being said, I think I've gotten one QSL back from a card sent with an IRC. Much better return with Greenstamps. I fold them an put them in the return envelope with the card and a blank piece of card stock. I also make sure no call sign or anything else that looks "Hammy" does not appear on the envelope.
That reminds me, gotta get few cards out...
