AMSAT AO-7 to Celebrate 50th Anniversary
It has often been reported that the oldest satellites still working in space
are the space probes Voyager 1 and Voyager 2. The Voyagers were both launched
in 1977 to take advantage of the planetary alignment called, back then, the
“Grand Tour”. Their images changed the human vision of our solar system.
[cid:
image001.jpg@01DB2D34.86D00290]
But, are they really the oldest, still functional spacecraft in outer space?
What if we include spacecraft that remained behind in Earth Orbit? Is it even
believable that the oldest still working satellite in space wasn’t even
designed or operated by NASA, USAF, ESA or any other space agency? What if
this satellite was designed by Radio Amateurs and the final assembly occurred
in a basement laboratory not far from Goddard Space Flight Center?
Then all things considered, AO-7, a SmallSat launched on November 15, 1974 is
the oldest working satellite and is still providing service to hundreds of
Amateur Radio operators around the world. In its first life, AO-7 lived a
very healthy lifetime of 6.5 years. Not to over-state the case, AO-7 outlived
both its commercial and government co-passengers launched by Delta-104.
In late 1980, AO-7’s poor, abused, NiCad battery began to show serious
signs of increased series resistance. This was a sure sign to AMSAT command
stations that the end was in sight. The cells had been originally matched for
capacity by NASA. And, indeed the cells all failed within a matter of weeks
of one another.
AO-7 stayed asleep for 21 years, to the nearest month. Then one day AO-7 woke
up again. This was only possible if something caused an open circuit in the
battery.
A very active user of AO-7, Pat Gowain, G3IOR, from the UK, made a telephone
call to Perry Klein, W3PK, (first AMSAT President and designer of the VHF/HF
transponder). This was on June 21, 2002. Pat wondered if we had launched a
new LEO spacecraft? He was hearing Morse Code Telemetry again on the old
beacon frequency of AO-7. He played Perry a tape recording. It sure sounded
like AO-7 telemetry!
Many radio amateurs who were satellite enthusiasts very quickly began to
observe the signals from AO-7 and the second life of the "Sleeping Beauty" of
satellites began.
Over the next three weeks in November AMSAT News Service will honor this
historic achievement with a series of short articles highlighting the life of
AMSAT OSCAR 7. In the meantime be sure to visit a special page on the AMSAT
website where you will find a collection of AO-7 articles and links at

Back to Basics: What is the CubeSat Launch Initiative?
(Editor's note: In this avocation, we sometimes toss around acronyms or
titles with scant understanding of what they stand for. From time to time,
ANS will offer short articles that can help up better understand the
vocabulary of amateur satellites.)
The CubeSat Launch Initiative, or CSLI, is a NASA initiative that provides
opportunities for qualified CubeSats to fly as auxiliary payloads on future
launches that have excess capacity or as deployments from the International
Space Station (ISS). In very simple terms that means that NASA will cover the
cost of providing a CubeSat a ride to space in exchange for a report on the
results of that CubeSat's investigation.
[cid:
image004.png@01DB2D34.86D00290]
NASA’s CubeSat Launch Initiative provides opportunities for CubeSats built
by U.S. educational institutions, and non-profit organizations, including
informal educational institutions such as museums and science centers to fly
on upcoming launches. Through innovative technology partnerships NASA
provides these CubeSat developers a low cost pathway to conduct scientific
investigations and technology demonstrations in space, thus enabling
students, teachers, and faculty to obtain hands-on flight hardware design,
development, and build experience.
CSLI provides a low-cost platform for NASA science missions, including
planetary exploration, Earth observation, and fundamental Earth and space
science. These efforts are a cornerstone in the development of cutting-edge
NASA enabling technologies including laser communications, next generation
avionics approaches, power generation, distributive sensor systems,
satellite-to-satellite communications, and autonomous movement. Leveraging
these missions for collaboration optimizes NASA’s technology investments,
fosters open innovation, and facilitates technology infusion. CubeSat
missions are enabling the acceleration of flight-qualified technology
assistance in raising Technology Readiness Levels, which aligns to NASA’s
objective of advancing the Nation’s capabilities by maturing cross-cutting
innovative space technologies.
About half of all CSLI missions are conducting scientific investigations,
most frequently Space Weather and Earth Science. Specific science
investigation areas include: biological science, study of near Earth objects,
climate change, snow/ice coverage, orbital debris, planetary science,
space-based astronomy, and heliophysics. Sixty-six percent of all CSLI
missions are conducting technology development or demonstrations.
Communications, propulsion, navigation and control, and radiation testing
lead the topics in this area. Other notable technologies are solar sails,
additive manufacturing, femtosatellites, and smart phone satellites. The low
cost of development for a CubeSat allows for conducting higher risk
activities that would not be possible on large-scale NASA missions.
What is the difference between CSLI and ELaNa?
NASA’s Launch Services Program manifests CSLI payloads with a variety of
launch providers. Each launch with manifested CSLI payloads is called an
ELaNa mission (Educational Launch of Nanosatellites) and is given an ELaNa
mission number (e.g., ELaNa 49, ELaNa 50). Simply put, CSLI is the payload
and ELaNa is the ride.
To be eligible for CSLI, a CubeSat investigation must be of clear benefit to
NASA by supporting at least one goal or objective stated in the NASA
Strategic Plan. This plan can be found on NASA’s Web site
http://www.nasa.gov.

Voyager 1 Resorts to Transmitter that Hasn't Been Used Since 1981
Following recent communication issues, NASA's Voyager 1 spacecraft resorted
to using a backup radio transmitter that has been inactive since 1981.
The interstellar explorer experienced a brief pause in communications after
putting itself in a protective state to conserve power. This was triggered by
a command sent on Oct. 16 instructing the spacecraft to turn on one of its
heaters.
[cid:
image007.png@01DB2D34.86D00290]
The mission's flight team first realized there was an issue with Voyager 1 on
Oct. 18, when the spacecraft failed to respond to that command. The team
later discovered that the spacecraft had turned off its primary X-band radio
transmitter and instead switched over to its secondary S-band radio
transmitter, which uses less power, according to a statement from NASA. The
transmitter shut-off seems to have been prompted by the spacecraft's fault
protection system, which autonomously responds to onboard issues.
The spacecraft's fault protection system switched to the S-band radio
transmitter, which, prior to that date, hadn't been used since 1981. Given
the spacecraft is located much farther away in interstellar space today than
it was 43 years ago, the flight team was not sure a signal on the S-band
frequency could be detected — especially because it transmits a
significantly fainter signal while using less power.
A command was sent to the S-band transmitter on Oct. 22. Two days later, on
Oct. 24, the team was finally able to reconnect with Voyager 1.
Voyager 1, which launched in 1977. Its time in deep space has taken a toll on
its instruments and caused an increasing number of technical issues. Earlier
this year, the team had to fix a separate communications glitch that was
causing the spacecraft to transmit gibberish. Read the complete story at

Changes to AMSAT TLE Distribution for November 1, 2024
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 daily in the first hour of the UTC day. New bulletin files will be
posted immediately after reliable elements become available for new amateur
satellites. More information may be found at
https://www.amsat.org/keplerian-elements-resources/.
The following satellites have been removed from this week's AMSAT TLE
distribution:
UVSQ-SAT NORAD Cat ID 43758 Decayed from orbit on or about 26 October 2024
TianYi 6 NORAD Cat ID 43158 Decayed from orbit on or about 18 October 2024

Satellite Shorts From All Over
* As millions of people around the world celebrate Diwali, the Hindu
festival of lights, NASA astronaut Sunita Williams radioed home a message of
festive cheer. "I want to extend my warmest wishes for a Happy Diwali to
everyone celebrating the festival of lights today at the White House and
around the world," Williams said in a recent video message sent from the
International Space Station. Speaking from the ISS' window-filled cupola with
Earth as her backdrop, Williams, who is an American with Indian heritage,
spoke about her father's efforts to keep Indian culture alive after he
migrated to the United States in 1957. She also touched upon the symbolism of
Diwali — the triumph of good over evil, light over darkness and hope over
despair. "Diwali is a time of joy as goodness in the world prevails," she
said. [ANS thanks Space.com for the above information.]
* In a few years, as part of the Artemis Program, NASA will begin the
creation of permanent infrastructure that will allow for regular missions to
the surface (once a year) and a sustained program of lunar exploration and
development. In a recent NASA-supported study, a team of researchers at the
University of Illinois Urbana-Champaign investigated a new method of sending
spacecraft to the Moon. It is known as “multimode propulsion,” a method
that integrates a high-thrust chemical mode and a low-thrust electric mode
– while using the same propellant. To break it down, a multimode thruster
relies on a single chemical monopropellant – like hydrazine or Advanced
Spacecraft Energetic Non-Toxic (ASCENT) propellant – to power chemical
thrusters and an electrospray thruster (aka. colloid thruster). The latter
element relies on a process known as electrospray ionization (ESI), where
charged liquid droplets are produced and accelerated by a static electric
field. Electrospray thrusters were first used in space aboard the ESA’s
LISA Pathfinder mission to demonstrate disturbance reduction. By developing a
system that can switch as needed, satellites will be able to perform
propulsive manuevers using less propellant, thus requiring fewer fuel
transfers. Read the complete story at
https://tinyurl.com/ANS-308-Propulsion.

* Has orbital debris gone out of control? In 1978, NASA scientists Donald
J. Kessler and Burton G. Cour-Palais proposed a scenario where the density of
objects in Low Earth Orbit (LEO) would be high enough that collisions between
objects would cause a cascade effect. In short, these collisions would create
debris that would result in more collisions, more debris, and so on. This
came to be known as the Kessler Syndrome, something astronomers, scientists,
and space environmentalists have feared for many decades. In recent years,
and with the deployment of more satellites than ever, the warning signs have
become undeniable. Currently, there is an estimated 13,000 metric tons
(14,330 US tons) of “space junk” in LEO. With the breakup and another
satellite in orbit – the Intelsat 33e satellite – the situation will only
get worse. Read the full report at
