Space as soon as our volunteers can post it.
Please send any amateur satellite news or reports to: ans-editor [at]
amsat.org
You can sign up for free e-mail delivery of the AMSAT News Service Bulletins

GreenCube is now designated Italy-OSCAR 117 (IO-117)
GreenCube Designated Italy-OSCAR 117 (IO-117)
On July 13, 2022, the GreenCube satellite was launched on a Vega-C launch
vehicle from the Centre Spatial Guyanais in Kourou, French Guiana. The
satellite project is managed by the S5Lab research team at Sapienza
University of Rome, and involves ENEA (the Italian National Agency for New
Technologies, Energy and Sustainable Economic Development) and University of
Naples. The satellite carries environmental and thruster payloads and as
well as a 70cm digipeater for amateur radio use.
At the request of the GreenCube teams, AMSAT hereby designates the satellite
as Italy-OSCAR 117 (IO-117). We congratulate all the involved teams, thank
them for their contribution to the amateur satellite community, and wish
them continued success on this and future projects.
[ANS thanks Drew Glasbrenner, KO4MA, OSCAR Number Administrator, for the
above information]
--------------------------------------------------------------------
The IO-117 (GreenCube) Club continues to grow
Because of the increasing interest and the quick appearance of instructional
material on making digipeated contacts through IO-117, the "GreenCube User
Club" has rapidly grown to more than 300 as reported by Doug Papay, K8DP.
Several individuals have blogs describing their operational set up that
enables them to take advantage of the great DXCC and VUCC opportunity:
Burt DeMarcq, FG8OJ, offers some nicely detailed instructions and good
advice on his blog at: https://bit.ly/3FjqM1f.
Fabio Roccatagliata, F5VKV, writes on the AMSAT-BB mailing group that the
UZ7HO Soundmodem is very useful for IO-117 but one must download
http://uz7.ho.ua/greentnc.zip for success as the tone spacing is shifted
from those normal for APRS. He continues: "Use the ssb modem, 1600 main
frequency in the spectrum. (Put the) Radio in usb, agc off if possible (or
fast), no noise blanker/reduction. You should receive the packet when the
signal is within the bandwidth bar you see in the sound modem spectrum.
Adapt the DCD threshold accordingly, usually by the half. In the green cube
GUI window you should see the decoded packets, in the sound modem the data."
Editor Note: The link to the zipped file is listed directly because it does
not yet appear on Andrey Kopanchuk's website).
Joe Pereira, VK5EI, suggested on the AMSAT-BB mailing group that the summary
by Tom Van den Bon, ZR6TG, is particularly helpful for newcomers. It may be
found in a blog post on Tom's website: https://bit.ly/3Uqpm9B.
Doug Papay sent a Friday update (which is growing rapidly) on the number and
DXCC distribution of contacts made on the bird:
As of 1400Z 2/Dec/2022 there have been 303 stations active on IO-117 since
31/Oct/2022. Congratulations to ZL3TKZ for contact #300!
There have been 154 stations heard in the last 24 hours. There have been 194
unique grid squares and 51 DXCC entities activated. Here is the DXCC list
including number of stations heard from each country:
United States of America 87

Dhruva Space- Thybolt Mission, Amateur Radio Payload Information
Dhruva Space launched the Thybolt Mission On 26 November, 2022, at 11:56 am,
onboard ISRO PSLV-C54. The Thybolt Mission consists of two 0.5U nano
satellites. These nanosatellites are built on the 0.5U P-DoT satellite
platform which is designed, built and tested by Dhruva Space for use in the
amateur communications, disaster management, and low bit-rate applications
of STEM and strategic importance. The qualification of this 0.5U platfo
rm
with its sub-systems will enable many more amateurs across India to learn,
build, launch and operate experiments on amateur satellite missions.
Information regarding the system and the the data modes they use may be
found at the Dhruva Space website: https://bit.ly/3FgYNz8 While it is not
clear whether the satellites will be active throughout their entire orbital
pathThe website states: "Please note that S&F Messaging will be available
after conclusion of launch & early phase and commissioning operations
tentatively on 20 December, 2022."
Nico Janssen, PA0DLO writes on the AMSAT-BB list:
"Doppler measurements show that Thybolt 1 and 2 are the objects 54363 and
54364. Current separation: 1 s, so it is not yet possible to determine which
is which.
CW beacon frequencies: Thybolt 1: 435.35447 MHz and Thybolt 2: 435.3522 MHz.
Nothing received on the telemetry frequency 436.175 MHz, but that downlink
is probably only active when in range of India."

Satellite Shorts From All Over
+ A new AMSAT distance record has been claimed on FO-29. KE9AJ in DM79IQ48UR
worked EB1AO in IN52PE28F at a distance of 7,642 km on 23-Nov-2022 at 20:46
UTC, edging out the previous record held by KG5CCI and F4DXV by 8 km. See
https://www.amsat.org/satellite-distance-records/ for all records. [ANS
thanks Paul Stoetzer, N8HM, AMSAT Executive Vice President & Ambassador for
the above information.]
+ Artemis I’s launch tower and deluge systems performed as designed. The
tower sustained some minor damage, particularly to the elevator (blew the
doors off), which will be repaired before the next launch.[ANS thanks The
Orbital Index for the above information.]
+ OMOTENASHI indeed was unable to be commanded to perform a landing burn.
Its operators hope that it has a stable spin axis and that enough sunlight
will reach it in the spring to establish comms and undertake secondary
mission objectives. [ANS thanks The Orbital Index for the above
information.]
+ Eutelsat Communications (Euronext Paris: ETL) (Paris:ETL) has selected
Thales Alenia Space (Thales 67 % and Leonardo 33 %) to build a
next-generation highly flexible, software-defined satellite (SDS). The
Flexsat (for flexible satellite) will be based on Thales Alenia Space's
cutting-edge 'Space Inspire' (INstant SPace In-orbit REconfiguration)
product line, enabling seamless reconfiguration and instant in-orbit
adjustment to offer an optimum level of customer service, maximising the
effective use of the satellite resources. [ANS thanks SpaceDaily.com for the
