ISS MAI-75 SSTV Activity Planned For Aug 4-5
Russian cosmonauts will transmit amateur radio Slow Scan Television
(SSTV) images from the International Space Station (ISS) during August
4-5 on 145.800 MHz FM (likely using PD-120).
On July 9, ESA Education had Tweeted: “We are expecting the ISS to
transmit pictures in the next weeks for the 45th anniversary of the
Apollo-Soyuz test project. This is a perfect opportunity to try this
activity for yourself!”
https://twitter.com/ESA__Education/status/1281140713237946370
Apollo–Soyuz was the first international space mission, carried out
jointly by the United States and the Soviet Union in mid-July 1975.
An announcement made July 27 on the ARISS SSTV Blog says: The final
crew schedule for the week of Aug 3-9 was released recently and it
showed a MAI-75 activity scheduled for Aug 4 and 5. This is soon after
the Space X Demo-2 undock so changes to that event could impact the
schedule.
The current dates and times of the planned activity are as follows:
Aug 4 (12:25-18:10 UTC) is setup and day 1 operations.
Aug 5 (11:15-18:45 UTC) is day 2 operations and close out.
This is the Moscow Aviation Institute SSTV experiment that is active
for orbital passes over Moscow, Russia. It has traditional been PD-180
or PD-120 and transmitting on 145.800 MHz.
Source ARISS STV Blog http://ariss-sstv.blogspot.com/
The ISS puts out a strong signal on 145.800 MHz FM and a 2m handheld
with a 1/4 wave antenna will be enough to receive it. Many FM mobile
and base station rigs can be switched been wide and narrow deviation
FM filters. For best results you should select the filter for wider
deviation FM (25 kHz channel spacing). Handhelds all seem to have a
single wide filter fitted as standard.
The space agency ESA has released a video ‘How to get pictures from the
International Space Station via Amateur Radio’ along with a collection
of Tutorial videos explaining how to receive ISS Slow Scan TV (SSTV)
pictures for different computers and mobile devices

How Many Satellite Awards Have Been Issued?
When Bruce Paige, KK5DO, AMSAT Director Contests and Awards, was asked
by a ham last week how many awards he has issued, his response was,
"You know, I really had no idea." Paige took over doing the AMSAT
awards in May, 2001. Most of the awards have computer records. However,
the Satellite Communicator Club award, he did not start keeping track
of until 2003.
So, you ask, how many awards has he issued? Paige says,
"Satellite Communicator 407+ but my records only go back to 2003
South Africa Satellite Communication Achievement 167
AMSAT Satellite Communication Achievement 273
Sexagesimal (60 QSOs) 64
Century (100 QSOs) 24
W4AMI (1,000 QSOs) 81
W4AMI endorsements (each additional 1,000 QSOs) 66
W4AMI 5000 (5,000 QSOs) 25
Rover 55
GridMaster 13
and if I added correctly, it comes out to 1,165 plus whatever Satellite
Communicator awards were issued in 2001 and 2002. That's a lot of
certificate paper, a lot of ink and a bunch of envelopes and stiffeners
to get them safely to their owners."
Do you have one on your wall? If not, maybe you should submit for one
or more so that one day I will hit 2,000 or 3,000 who knows. Visit the
awards page at https://www.amsat.org/awards-2/

First Demonstration Of Orbit Control On A 1U CubeSat
The University Wuerzburg Experimental Satellite 4 (UWE-4) successfully
used its propulsion system in order to conduct orbit control. The 1U
CubeSat, developed and built at the Chair for Robotics and Telematics,
is equipped with the electric propulsion system NanoFEEP which has been
developed by TU Dresden.
Several manoeuvres have been performed within 11 days between June 23
and July 3, 2020 such that the altitude of the CubeSat was reduced by
more than 100 meters, compared to an average of 21 meters with natural
decay. This marks the first time in CubeSat history that a 1U CubeSat
changed its orbit using an on-board propulsion system.
As chance would have it, the team of UWE-4 received a conjunction data
message (CDM) in the morning of July 2, 2020 from the United States Air
Force’s 18th Space Control Squadron. A conjunction of UWE-4 with a non-
operational Iridium satellite (ID: 34147) in the morning of July 5,
2020 with a minimum range of about 800 meters was a threat to the
safety of UWE-4. An analysis has shown that the altitude of UWE-4 would
already be below the Iridium satellite at the time of conjunction. Thus
the on-going altitude lowering manoeuvre could only improve the situa-
tion and can be considered as a collision avoidance manoeuvre. No furt-
her CDMs have been issued regarding this possible conjunction. An anal-
ysis of the orbit of the two spacecraft after July 5, 2020 results in
a closest approach of more than 6000 meters.
Lowering the altitude of a spacecraft in low earth orbit (LEO) is
equivalent to a reduction of its lifetime, since satellites in LEO
usually burn up during re-entry due to the friction with the Earth’s
atmosphere. Thus, this experiment is a concept demonstration of a de-
orbiting manoeuvre shown at the smallest class of spacecraft in LEO.
Today, there is no commitment to carry a propulsion system for space-
craft. However, due to the vastly increasing number of satellites in
mega constellations such obligations are being discussed in the space
agencies of several space faring countries. The experiment of UWE-4
presents a de-orbiting solution for the fraction of space debris of
operational but unused satellites of today and for the mega constella-
tions of tomorrow.
[U.S. regulations make the ability to de-orbit a requirement for HEO
amateur satellites in the future -- Ed.]
Stay tuned for more updates on UWE-4 and the upcoming launch of NetSat,
a formation flying nano-satellite mission from the Center for Telema-
tics which is expected to be launched September 2020!
Kind regards, The UWE-4 Team

Burns Fisher, WB1JF, Featured Speaker at AMSAT SA Symposium
AMSAT of South Africa (AMSAT SA) has converted its annual Space Sympo-
sium into a live online event to take place from 08:00z to 17:00z on
Saturday 22 August with a lunch break to have your sandwiches at home.
Burns Fisher, WB1JF, IHU Software Engineer and key volunteer in the
construction of the Fox1 series of satellites, will join the symposium
from the USA with two presentations. In one of his papers Burns will
present a small, easy-to-deploy telemetry station called Fox-in-a-Box,
a good way for amateurs to get started in satellite telemetry collec-
tion with a modest investment.
There will be features about AMSAT OSCAR 7, the longest operating ama-
teur satellite, as well as about SATNOGs and how to track and decode
thousands of small satellites in orbit with simple hardware/software
requiring minimal outlay. Dr. Hannes Coetzee, ZS6BZP, and his team will
present the latest developments in the AfriCUBE project.
To book, visit www.amsatsa.org.za. Members of the SARL or AMSATSA and
may register before 15 August for a cost of only R30. Non-members may
register prior to this date for a cost of R100 (approximately $6 U.S.)
but the AMSAT SA website only offers instructions for registration via
postal mail. Contact AMSAT SA to explore other possible options.

NASA to Provide Coverage of Astronauts' Return from ISS on SpaceX
NASA will provide live coverage of activities leading up to, during,
and following the return of the agency's SpaceX Demo-2 test flight with
the agency's astronauts Robert Behnken, KE5GGX, and Douglas Hurley from
the International Space Station.
The duo arrived at the orbiting laboratory on May 31, following a suc-
cessful launch on May 30 on a SpaceX Falcon 9 rocket from NASA's Ken-
nedy Space Center in Florida.
NASA and SpaceX are targeting 7:34 p.m. EDT Saturday, Aug. 1, for un-
docking of the Dragon "Endeavour" spacecraft from the space station and
2:42 p.m. Sunday, Aug. 2, for splashdown, which will be the first re-
turn of a commercially built and operated American spacecraft carrying
astronauts from the space station.
Coverage on NASA TV and the agency's website will begin at 20.30z on
Aug. 1, with a short farewell ceremony on station and resume at 21.00z
with departure preparations through splashdown and recovery at one of
seven targeted water landing zones in the Atlantic Ocean or Gulf of
Mexico off the coast of Florida.
