AMSAT at Hamvention
This issue of the AMSAT News Service bulletins is being produced at the
AMSAT booth at Hamvetion 2024 in Xenia, Ohio. AMSAT has a major presence at
Hamvention, with booths devoted to teaching satellite basics, membership
recruitment, the AMSAT Store, Engineering, Education, and the Ambassador
program.
Traffic was heavy on Friday morning, May 17, as soon as Hamvention opened
its doors. While some came directly to the AMSAT booth with their
questions, or to make purchases at the Store, many other ham attendees were
attracted by the displays as they wandered through the several Hamvention
venues.
Volunteer members of the AMSAT Engineering team were on hand to show off
models of the GOLF-Tee and Fox Plus satellites currently under
construction. Engineering team members also discussed various projects that
are part of the ASCENT program, developing possible components for future
satellites.
At the Education booth, Cubesat SIM models were transmitting actual
telemetry and slow-scan TV data across the table, demonstrating how these
tools can be assembled and used in classrooms and other settings to provide
hands-on instruction in satellite basics.
At the “Beginners Corner,” experienced satellite operators answered
questions and helped the curious to understand how easy and exciting it is
to get started in this fascinating aspect of the amateur radio hobby. Rain
on Friday morning prevented live satellite demonstrations, but these took
place as satellite passes and Hamvention circumstances permitted on
Saturday and Sunday.
The sixteenth annual joint AMSAT/ TAPR Banquet was held on Friday evening
at the Kohler Presidential Banquet Center in Kettering, Ohio, just south of
Dayton. This year’s banquet speaker was Bill Reed, NX5R, AMSAT PACSAT
Project Manager, who highlighted the forthcoming PACSAT digital
communications payload. This payload is drawing on lessons learned from
previous digital satellites to provide smoother operations for users in the
future.
The AMSAT Forum was held on Saturday afternoon. Robert Bankston KE4AL,
AMSAT President, highlighted recent activities within AMSAT and discussed
some of our challenges, accomplishments, projects, and late breaking news
(See following story). Jerry Buxton, NØJY, AMSAT Vice President for
Engineering, provided a video status update about upcoming satellite
missions currently in development. Alan Johnston, KU2Y, AMSAT Vice
President Education Relations, spoke about opportunities for using the
AMSAT CubeSat Simulator in educational settings. Drew Glasbrenner, KO4MA,
Vice President Operations, briefed those attending on the status of current
satellites. And Frank Karnauskas, N1UW, Vice President of AMSAT
Development, reported on the AMSAT Youth Initiative and its features.
Attendance was steady at all AMSAT exhibits throughout the Hamvention
weekend, and satellite operators enjoyed meeting, fact to face, the voices
and callsigns encountered on the satellites.

Multiple QO-100 DX-Peditions to VO1
This week sees three separate groups operating from just outside the
coverage footprint of the QO-100 satellite.
>From Newfoundland the geostationary QO-100 satellite is nominally 1 degree
below the horizon. After 5 years in orbit and much speculation, three
groups are in the St. John’s area to try operating QO-100 with its S band
uplink and 10GHz downlink.
First in Newfoundland was Gopan, M0XUU. He was operating with a 0.8m dish
from just north of the harbor entrance and updates could be found on the
QO-100 DX Club web site. https://qo100dx.club/ Despite frequency periods of
no signal or deep QSB, Gopan managed to work stations via FT8, FT4, and CW.
After a week on the air as VO1/M0XUU, Gopan left Newfoundland on May 15.
Arriving Monday 13 May and remaining until to Friday 17, was a Canadian
team with a 1.8m dish and up to 100W. Poor weather hampered their
operations. Details of the operation by Stefan Wagener, VE4SW, and John
Langille, VE1CWJ, can be found at the QRZ.com page for special callsign,
VO100QO at https://www.qrz.com/db/VO100QO
Finally, Graham Shirville, G3VZV, and David Bowman, G0MRF, arrived on
Wednesday, May 15 with two sets of equipment and were active as VO1/G3VZV
and VO1/G0MRF. They will fly back to the UK early Sunday, May 19. Operating
from the old lighthouse keepers bungalow on the southern side of the harbor
entrance, GN37PN85, they attempted working all modes including an attempt
with DATV with a 175W S band amplifier. When not actively on the bands, a
personal beacon was operating on 10489.539 MHz in CW to act as a
propagation indicator.

Lost and Found: Missing Satellite Rediscovered
After 25 years lost in the vastness of space, a missing satellite has
finally been located, highlighting the challenges of tracking the multitude
of objects orbiting Earth. The rediscovery sheds light on the difficulty of
monitoring the approximately 27,000 objects that populate Earth’s orbit, a
number that continues to grow with each rocket launch and satellite
deployment.
The satellite in question, the Infra-Red Calibration Balloon (S73-7), was
part of the United States Air Force’s Space Test Program and was launched
in 1974. Its purpose was to serve as a calibration target for remote
sensing equipment, but a deployment failure left it adrift as space debris.
Despite initial attempts to track its whereabouts, it vanished from
ground-based sensors in the 1990s, only to resurface last month.
*The Air Force’s KH-9 Hexagon satellite deployed the tiny IRCB (S73-7)
satellite in 1974. (Illustration: U.S. Air Force)*
Jonathan McDowell, an astrophysicist from the Harvard-Smithsonian Center
for Astrophysics, discovered the satellite’s reappearance while reviewing
archival data. He explained that the satellite’s low radar cross section
and possible malfunctioning equipment made it difficult to detect. This
underscores the challenges faced by ground-based radar and optical sensors
tasked with monitoring objects in orbit.
Tracking objects in space is akin to air traffic control, with sensors
relying on identifying the orbit of moving objects and matching them with
designated satellite orbits. However, this becomes increasingly complex as
Earth’s orbit becomes more congested, particularly in geostationary orbit
where monitoring is hindered by a lack of radars positioned precisely on
the equator.
*A screenshot of a screenshot of a graph Description automatically
generated*
The Department of Defense’s Space Surveillance Network currently tracks
over 27,000 objects, predominantly defunct satellites and debris. As the
number of satellites and rocket launches continues to rise, maintaining
accurate tracking becomes crucial to mitigate the risk of collisions and
space debris hazards.
While the rediscovery of the missing satellite serves as a reminder of the
challenges of space tracking, it also underscores the importance of
continued efforts to monitor and manage Earth’s orbital environment. With
technology evolving and space activity increasing, effective space
surveillance remains paramount to ensure the safety and sustainability of
activities in Earth’s orbit.

Starliner: A Decade of Challenges
Boeing is delaying its first flight with humans on its Starliner spacecraft
yet again, the company said on May 14. The launch, which has been delayed
for years and was most recently scheduled for May 18, was pushed back until
Tuesday afternoon, May 21 at the earliest because of a helium leak.
Boeing’s Starliner spacecraft marks the culmination of a tumultuous journey
fraught with setbacks and challenges. What’s surprising isn’t merely
Boeing’s eventual loss in the commercial crew space race to SpaceX but
rather the fact that Boeing managed to reach this point at all.
The story traces back a decade when NASA’s human spaceflight leaders
convened to select a replacement vehicle for the retired Space Shuttle.
Boeing emerged as the frontrunner, backed by its illustrious history in
spaceflight. However, the eventual decision to award contracts to both
Boeing and SpaceX marked the beginning of Boeing’s struggle to adapt to the
demands of a fixed-price environment.

rocket for its first crewed launch. [Credit: NASA/Cory Huston]*
Unlike SpaceX, which was already immersed in multiple space projects,
Boeing found itself grappling with a new paradigm. Accustomed to cost-plus
contracts, where expenses could be billed to the government, Boeing now
faced the challenge of delivering a spacecraft within strict budget
constraints. This shift exposed deep cultural and structural inefficiencies
within the company.
Boeing’s difficulties were compounded by technical hurdles, particularly in
software development and propulsion. Fragmented software teams and strained
relationships with suppliers like Aerojet Rocketdyne hindered progress. The
consequences of these challenges became evident during Starliner’s
ill-fated uncrewed test flight in 2019, marred by critical software errors
and propulsion anomalies.

mission in 2022 [Credit: NASA/Joel Kowsky]*
While Boeing struggled, SpaceX surged ahead, buoyed by its vertically
integrated approach and a culture of innovation. SpaceX’s success
underscored the shortcomings of Boeing’s traditional aerospace model,
further exacerbated by broader crises within Boeing’s aviation division,
notably the 737 MAX disasters and the COVID-19 pandemic.
Boeing’s tumultuous journey with Starliner offers valuable lessons about
the perils of resisting change and the imperative of embracing innovation
in the rapidly evolving space industry. Despite its setbacks, Boeing’s
perseverance underscores the dedication of the engineers and technicians
who tirelessly worked to bring Starliner to fruition.

Changes to AMSAT-NA TLE Distribution for May 16
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 satellite has been removed from this week’s AMSAT-NA TLE
distribution:

Satellite Shorts From All Over
+ Congratulations to Maksym “Max” Romenskyy, SA5IKN, M0SKN, US6IKN, EI6KC,
who has earned his THIRD *satellite Worked All Zones (WAZ) award*, this
time as EI6KC #121. This is the first WAZ Satellite Award in Ireland. He is
also the first in the world to complete three WAZ Satellite Awards from
three different locations in three countries. He already holds a special
plague “IN RECOGNITION OF WORLD # 1 SAT WAZ AWARD WITH TWO CALLS” for WAZ
awards #40 as SA5IKN (38 zones) and #92 as MØSKN. (ANS thanks Max
Romenskyy, US6IKN, for the above information.)
+ Since April 28, 2019, *the Swiss satellite net on QO-100* has been a
consistent weekly event, marking its fifth anniversary on the same date in
2024. Hosted by HB9RYZ initially and later by HB9TSI from Italy, the round
convenes every Sunday at 9:00 p.m. on 10489.740 MHz, typically with 5 to 10
participants, though 15 joined for the anniversary round. Led by Paul,
HB9DFQ, the round maintains a familiar format: participants check in, share
station updates and radio experiences, delve into topics, and bid farewell.
Despite no specific celebration planned, the anniversary drew a hearty
attendance. Notable moments include Roman, HB9HCF’s reports from Antarctica
during the pandemic, while regular attendees like IS0/HB9SJP and supportive
listeners add to the camaraderie. The inaugural round was preserved on
Soundcloud by HB9WDF, encapsulating the enduring spirit of this community
gathering. (ANS thanks AMSAT-HB for the above information for the above
information)
+ The recently released *GreenCube BackPack antenna by Arrow Antennas*,
designed specifically for IO-117 satellite communication, can now be
purchased from their website for $219. It boasts a three-piece split boom
design and 15 UHF elements, along with a pre-assembled and pre-tuned Gamma
Match compatible only with BNC connectors. Engineered for maximum gain and
efficiency, the antenna utilizes aluminum Arrow Shafts for its elements and
a 3/4″ square boom measuring 116.8″ in length. Mounting near its balance
point is recommended due to its weight, and plastic tips ensure safety.
While the foam handle grip can be removed using isopropyl alcohol, using
the tripod hole for mounting is discouraged due to balance issues.
Additionally, customers have the option to purchase a separate element set
for cross-polarized antenna configuration, priced at $99.00. Info at
https://arrowantennas.com/arrowii/greencube.html (ANS thanks Arrow
Antennas, for the above information.)
+ Prof. Robert “Bob” Twiggs, KE6QMD, and a group of former students and
colleagues are working on gathering and publishing a series of books on *the
history of the creation and adoption of the CubeSat*. Take a look at the
LinkedIn announcement here: https://lnkd.in/eNZgv6Tk. If this sounds like
something you’d be interested in supporting, please take a look at our
GoFundMe page here: https://www.gofundme.com/f/cubesat-history-project. The
community’s response has been amazing! Over a hundred interviews were
conducted, and countless images and documents from the earliest days of the
CubeSat were collected! The result is that we have accumulated one of the
most comprehensive histories of the CubeSat, with many unique,
never-before-told stories! Reach out if you are interested in sponsoring
the project to get a signed copy and your organization’s name in the book.
Please email Dr. Aaron Zucherman at azucherman @ gmail.com. (ANS thanks Aaron
Zucherman, KM6CHY, for the above information.)
+ Last week, as Sol continues to edge into the most active phase of its
11-year cycle, *multiple massive X-class solar flares* (the largest an X5.8
flare) erupted from associated active sunspots, along with coronal mass
ejections (CMEs) directed towards Earth. This sustained activity caused a
G5 solar storm last weekend (NOAA’s space weather scales for reference),
leading to aurorae visible from middle latitudes as far south as Puerto
Rico in the US and all over Europe. This was one of the most powerful solar
storms since an estimated X28-45 flare in 2003 contributed to the 2003
Halloween solar storms that damaged or interrupted services from multiple
spacecraft, saturated measurement instruments, and made ISS astronauts
shelter in the more shielded Russian segment. (ANS thanks The Orbital Index
for the above information.)
+ Japan’s Moon Sniper, also known as *SLIM, has astounded experts by
surviving its third lunar night*, despite not being designed for such harsh
conditions. Initially landing near the Shioli Crater on January 19, the
spacecraft encountered an anomaly during descent, landing on its nose and
facing west, hindering its solar panels’ ability to generate power.
However, Moon Sniper continues to defy expectations by waking up after each
lunar night, transmitting new images before going back into hibernation.
Despite enduring both the extreme cold of the lunar night and the searing
temperatures of the lunar day, the spacecraft has maintained functionality,
prompting close monitoring from the mission team to identify potential
deteriorating components. As Moon Sniper enters hibernation again, the team
plans to resume operations in May, expressing gratitude for ongoing support
and even composing a song titled “15 Degree Slope” to commemorate the
mission’s unexpected journey. (ANS thanks CNN for the above information.)
