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 âGrand Tourâ. Their images changed the human vision of our solar system.
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 wasnât 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-7âs 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.
NASAâs 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 NASAâs 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 NASAâs objective of advancing the Nationâs 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?
NASAâs 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 NASAâs 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.
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 â 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
