Amateur Radio Operator Contacts Spacecraft
The headlines are sensational, although a bit exaggerated: "Ham Radio
'hacks' NASA Satellite". While the phrase is eye-catching for social media,
the truth is just as exciting. Amateur radio astronomer Scott Tilley,
VE7TIL, has made contact with NASA's STEREO-A spacecraft, which passed
Earth for the first time in 17 years.
The STEREO-A (Solar TErrestrial RElations Observatory) spacecraft was
launched on October 25, 2006, from Cape Canaveral, Florida, with its twin
sister ship, STEREO-B. Both spacecraft were on a mission to circle behind
the and send images back to Earth so scientists could make 3D models of
solar activity. In 2014, STEREO-B failed and was not heard from again.
"I'm having fun with STEREO-A," Tilley reported to Spaceweather.com. "The
spacecraft is close to Earth this summer, and I can now receive its signal
using a small 26-inch dish in my backyard."

spacecraft. [Photo courtesy of Scott Tilley]
Tilley began hearing rumors that other radio operators were picking up
signals from STEREO-A on 8443.580 MHz. He decided to check it out. "The
central carrier is very loud, almost 30 dB above the noise," he said. "I
also noticed data sidebands, which are unusual to see on such a distant
object for my small antenna."
Tilley was able to decode and demodulate STEREO-A's signal using a special
program written by Alan Antonie, F4LAU, known as SatDump, and now, he is
monitoring almost all of STEREO-A's science instruments, including its
Extreme Ultraviolet Imager (EUVI), two coronagraphs (COR1 and COR2), the
heliospheric imager (HI), and a solar radio burst receiver (S/WAVES).
STEREO-A's closest approach to Earth was scheduled to occur on August 17,
2023.
Amateur radio operators who would like to monitor STEREO-A can check out
Tilley's technical blog for more information.

Changes to AMSAT-NA TLE Distribution for August 18, 2023
Two Line Elements or TLEs, often referred to as Keplerian elements or keps
in the amateur community, are the inputs to the SGP4 standard mathematical
model of spacecraft orbits used by most amateur tracking programs. Weekly
updates are completely adequate for most amateur satellites. TLE bulletin
files are updated Thursday evenings around 2300 UTC, or more frequently if
new high interest satellites are launched. More information may be found at
https://www.amsat.org/keplerian-elements-resources/
This week there are no additions or deletions to the weekly AMSAT TLE
distribution.

ARISS News
Amateurs and others around the world may listen in on contacts between
amateurs operating in schools and allowing students to interact with
astronauts and cosmonauts aboard the International Space Station. The
downlink frequency on which to listen is 145.800 MHz worldwide.
Quick list of scheduled contacts and events:
STEMforGIRLS, St. John’s, Newfoundland and Labrador, Canada, telebridge via
K6DUE (***)
The ISS callsign is presently scheduled to be NA1SS
The downlink frequency is presently scheduled to be 145.800 MHz

Comments on making general contacts
I have been seeing a lot of traffic on Facebook and I suspect on other
social media sites with people asking why they are not hearing the crew
make general contacts. First off the crew is very busy on the ISS and they
simply may not have the time to just pick up the microphone and talk.
Also, one needs to be aware of their normal daily schedule. I have listed
below the constraints that we at ARISS have to follow in order to schedule
the school contacts. Hopefully this will help you better schedule your
opportunities.
Typical daily schedule
Wakeup to Workday start= 1.5 hours
Workday start to Workday end=12 hours
Workday end to Sleep= 2 hours
Sleep to wakeup= 8.5 hours
The crew's usual waking period is 0730 - 1930 UTC. The most common times to
find a crew member making casual periods are about one hour after waking
and before sleeping, when they have personal time. They're usually free
most of the weekend, as well.
SSTV events are not that often. So please check out https://www.ariss.org/
for the latest information or watch for the ARISS announcements.
And don’t forget that the packet system is active.
As always, if there is an EVA, a docking, or an undocking; the ARISS radios
are turned off as part of the safety protocol.
ARISS Radio Status
Columbus Module radios:
IORS (Kenwood D710GA) – STATUS - Configured. Default mode is for cross band
repeater (145.990 MHz up {PL 67} & 437.800 MHz down).

Upcoming Satellite Operations
TF/DL2GRC: Got an email from Nina stating that she & the family will be
heading to Iceland with operations scheduled to begin on Friday (18th).
>From Nina:
We will do a trip around the Island and hope to be active on MEO, LEO and
GEO: family, equipment, satellites and weather permitting. Operations can
be expected between August 18th to 30th. Please keep in mind, it will be a
family holiday and no DX-pedition.
Look out for TF/DL4BEN, TF/DL8SCU and TF/DL2GRC.
Stay tuned!

Satellite Shorts From All Over
+ RS-44 has returned to service after a multi-day outage this past week.
There is no definitive word on the cause of the outage.
+ Woody Hoburg, KB3HTZ, was active as NA1SS from the ISS, utilizing the FM
repeater, on Monday, August 14th around 1900 UTC and Wednesday, August 16th
around 2100 UTC (ANS thanks ARISS for the above information)
+ NASA released its updated Software Catalog for 2023-2024, containing more
than 1,000 programs for mission analysis, disaster response, spacecraft
testing, data analytics, and more. Access restrictions apply to some
software that may be limited to use by U.S. citizens or for U.S. government
purposes only. Review the catalog online at: http://software.nasa.gov (ANS
thanks The Orbital Index and NASA for the above information)
+ NASA will provide live launch and docking coverage of the Roscosmos
Progress 85 cargo spacecraft carrying about three tons of food, fuel, and
supplies for the Expedition 69 crew aboard the International Space Station
(ISS). The unpiloted spacecraft is scheduled to launch at 01:08 UTC on
Wednesday, Aug. 23 on a Soyuz rocket from the Baikonur Cosmodrome in
Kazakhstan. The Progress spacecraft will be placed into a two-day, 34-orbit
journey to the station, leading to an automatic docking to the Zvezda
module at 03:50 UTC Friday, Aug. 25. As always, amateur radio operation
aboard the ISS is suspended during docking maneuvers. The spacecraft will
remain at the orbiting laboratory for approximately six months, then undock
for a destructive but safe re-entry into Earth’s atmosphere to dispose of
trash loaded by the crew. (ANS thanks NASA for the above information)
+ India's Chandrayan-3 moon lander completed another lunar-orbit reduction
burn and entered a 100 km circular polar lunar orbit ahead of a landing
attempt next week. It is projected that the Indian craft will land two days
after Russia's Luna-25 lander. (ANS thanks The Orbital Index for the above
information)
