    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 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 week's AMSAT-NA TLE distribution:

    + 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. [ANS thanks the European Space Agency for the above information]
