CubeSat: Celebrating 20 Years of Transforming Space Access
Twenty years ago, an invention emerged from the labs of Cal Poly San Luis
Obispo that would change the face of space exploration forever. The CubeSat,
a tiny satellite with the dimensions of a square tissue box, revolutionized
access to space, making it more affordable and achievable for researchers and
students alike.
The brainchild of professors Jordi Puig-Suari and Bob Twiggs, the CubeSat was
born out of the need to solve a crucial problem. While universities aimed to
train students through hands-on experience, getting their satellites into
space was a daunting challenge due to the limited access to rockets and the
high costs associated with launches.
The innovative solution was simple yet effective, the CubeSat. They designed
a standardized, risk-containment mechanism where all the risk of potential
failure would be confined within the small box. This not only addressed the
rocket providers' concerns about carrying student-built satellites but also
reduced the cost and time required to send satellites into orbit.
The CubeSat's impact was profound and far-reaching. Almost every rocket
launched into space today carries CubeSats on board. The small satellite
became an open standard, meaning anyone could use it without any charges,
promoting uniformity and standardization across the industry.
Unlike traditional satellites that could take years and cost hundreds of
millions of dollars to build, CubeSats presented a cost-effective
alternative. Building a CubeSat was a fraction of the expense, and the
standard's versatility allowed various scientific missions, ranging from
Earth observation and mapping to space exploration. The CubeSat opened the
doors to space for many countries that launched their first-ever satellites,
including Colombia, Switzerland, Hungary, Vietnam, and more.
Private companies also capitalized on the CubeSat revolution, stepping in as
intermediaries between satellite creators and rocket providers. Companies
like Maverick Space Systems acted as "Uber for satellites," arranging rides
for satellites of various sizes, including CubeSats, on rockets for
commercial and government clients.
The CubeSat's impact also extended to educational institutions. Cal Poly's
CubeSat Lab provided students with hands-on experience, allowing them to
design, build, and even launch CubeSats. The educational aspect of CubeSats
became so popular that high school students at Grace Brethren High School in
Simi Valley also had a class on spacecraft engineering, learning about
CubeSats and building AMSAT CubeSat Simulators (CubeSatSim).
The CubeSatSim Project, led by Dr. Alan Johnston, KU2Y, AMSAT Vice President
Educational Relations, is an initiative sponsored by AMSAT. It involves the
development of a low-cost satellite emulator called CubeSatSim, designed with
solar panels, rechargeable batteries, and UHF radio telemetry transmission
capabilities. The CubeSatSim features a 3D printed frame and can be expanded
with additional sensors and modules. The project aims to provide an
accessible platform for educational purposes. Detailed documentation and
build instructions are available on the project's Wiki at
https://github.com/alanbjohnston/CubeSatSim.
As the CubeSat celebrates its 20th anniversary, it stands as a testament to
the power of innovation and the impact of an open standard in transforming an
entire industry. What began as a solution to a niche problem has now become
an integral part of space exploration, enabling researchers, students, and
commercial ventures to access space like never before. The CubeSat's legacy
is imprinted in space, as these tiny satellites continue to leave their mark
on missions, both in orbit and beyond.

ARRL Releases LoTW Configuration 11.25 with LEDSAT Support
The American Radio Relay League (ARRL) has recently unveiled the latest
version of the Logbook of The World (LoTW) configuration file, version 11.25,
which includes support for LEDSAT, an educational 1U CubeSat developed by
students from Sapienza University in Rome's S5Lab research team, with backing
from AMSAT Italia.
LEDSAT's primary objective is to demonstrate a LED-based payload for
ground-based optical tracking. One of the notable features of LEDSAT is its
digipeater capability, which allows it to store and retransmit digital
messages sent to the satellite, effectively acting as a transponder for
long-distance communication.
When opening ARRL's TQSL (Trusted QSL) application, an "Update Available"
dialog box will display if a newer configuration file is available. Simply
click the 'OK' button to install the latest configuration file. You can
easily determine whether a new version of TQSL or its Configuration Data is
available by selecting the "Help" menu and clicking on "Check for
Updates...". The latest version of TQSL (version 2.6.5) can be downloaded
from https://www.arrl.org/tqsl/tqsl-2.6.5.msi.
Additionally, the GreenCube Terminal program developed by Carsten Groen,
OZ9AAR, now includes support for communications with the LEDSAT digipeater by
utilizing the "Soundmodem for GreenCube" TNC application created by Andy
Kopanchuk, UZ7HO. The latest release of the GreenCube Terminal program
version 1.0.0.62 was provided on July 22, 2023. More information can be found
at https://moonbounce.dk/hamradio/greencube-terminal-program.html.

Changes to AMSAT-NA TLE Distribution for July 28, 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. Elements in the TLE
bulletin files are updated daily. TLE bulletin files are updated to add or
remove satellites as necessary 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/.
The following satellite has been added to this week's AMSAT-NA TLE
distribution:
MRC-100 NORAD Cat ID 56993 IARU Coordinated Frequency: 436.720 MHz.
(Thanks to Nico Janssen, PA0DLO for identification).
The following satellite has decayed from orbit and has been removed from this

+ On July 23, a SpaceX Falcon 9 rocket launched from Cape Canaveral Space
Force Station with 22 additional satellites for the Starlink communications
constellation. During the launch, the rocket created a temporary hole in the
ionosphere, also known as a rocket exhaust depletion (RED), by releasing
exhaust that interacts with charged oxygen atoms, creating a reddish patch.
Although the damage is not permanent and mainly affects amateur radio
signals, the increasing frequency of such occurrences due to the growing
number of satellite launches has raised concerns among scientists about the
potential impact on the ozone layer, as rocket exhaust releases various toxic
chemicals into the atmosphere. Stricter controls for the launch services
industry have been called for to address this issue. [ANS thanks Aditya
Madanapalle, writing for News9 Live, for the above information]
+ The preparation for Ariane 6's inaugural flight is going well, as the teams
completed a launcher preparation and countdown sequence successfully at
Europe's Spaceport in Kourou, French Guiana on 18th July. The test included
various critical tasks such as removing the mobile gantry, chilling down
fluidic systems, and filling the tanks with liquid hydrogen and liquid
oxygen. The launch chronology was also completed up to the ignition of the
Vulcain 2.1 engine. During the 26-hour exercise, degraded and contingency
modes were tested, demonstrating the launcher and launch base's proper
functioning. Although the ignition of the Vulcain 2.1 engine had to be
postponed to a later session, the overall performance of the full launch
system was excellent. The teams are confident about the progress of the test
campaign and are preparing for a long duration hot firing test in the summer.
