    Updated "For Beginners" Compilation Now Available on the AMSAT Website

    An updated freely downloadable compilation of “getting started
    written by Keith Baker, KB1SF/VA3KSF, is now available on the AMSAT
    website. These articles originally appeared in The AMSAT Journal from 2019
    to 2021.

    Check out the compilation at https://www.amsat.org/introduction-to-working-amateur-satellites/

    Unfortunately, because both satellites and URLs change over time, the currentness of information such as this can quickly be overcome by events. However, the tools and techniques outlined in Keith’s beginner seri
    es are
    still very much applicable to operating on current and future AMSAT
    satellites. For the latest information about satellites currently in orbit, please consult the AMSAT Communications Satellites page.

    More detailed information can be found in AMSAT's Getting Started with
    Amateur Satellites book which can be purchased on the AMSAT store.

    TX5S DXpedition to Clipperton Island to Include Satellite Operations

    The TX5S DXpedition to Clipperton Island, scheduled for January 2024, has announced that it will include satellite operations. The satellite station manager, Andreas, N6NU, reports the following preparation
    activities for the TX5S DXpedition to Clipperton Island:

    Andreas has made his first QSO’s made on the IO-117 (GreenCube) Sat
    This satellite has passes that last over an hour and has a huge footprint
    since it is in an almost 6,000 KM orbit. He has an 11 Element 70CM antenna,
    RAS Mini AZ/EL rotator with Green Heron Controller, Icom IC-9100H,
    Rigblaster TI-5000 and Icom AG-35 mast mounted pre-amp. The 6ft mast uses a home brew base. The next step is to configure an Icom IC-9700 as backup.
    Then on to RS-44 and 6m and 23 cm EME. He appreciates the help and advice offered by several AMSAT members.

    2023 AMSAT Field Day Preliminary Report

    The 2023 AMSAT Field Day is over, and early data shows how the satellites
    were utilized.

    It has been many years since there were more than one or two AMSAT Field
    Day submissions from outside North America. This year, immediately after of Field Day ended, there were two submissions from Japan.

    The satellites worked well. The FM Tevel family of satellites and GreenCube seemed to be popular. SO-50, AO-91, and the International Space Station
    were also busy with their FM single channels. RS-44 was quite tame, with
    plenty of bandwidth for many to make contacts, whether they were sitting on
    a frequency and calling CQ or using the hunt-and-pounce method.

    More data is on the way. For updates, visit the AMSAT website.

    Communication Problems on the Moon

    The chilly relationship between the U.S. and China on Earth could raise
    safety risks in space and the specter of competition on the Moon as both nations aim to send people to the lunar surface in the coming years.

    China and the U.S. — the two most dominant players in space today
    — do not
    generally collaborate on space research and exploration, and they have
    limited communication in orbit and beyond. But both nations are separately sending missions to the Moon. NASA expects its astronauts will be back on
    the surface of the Moon as early as 2025, and China has plans for its taikonauts to land on the lunar surface by around 2030.

    The Chinese military is refusing to use established communications channels that could help to prevent an unintended crisis on Earth. Recent close
    calls between U.S. and Chinese crafts at sea and in the air underscore the risk.

    Lack of transparency into activities has framed the U.S-China relationship
    in space for decades, with some key exceptions, including coordinating
    orbiters at Mars and NASA collaborating with China during one of the
    nation's robotic Moon missions.

    The Chinese government has a fundamentally different way of engaging in the world that makes open communication difficult, Dean Cheng, a China analyst, tells Axios. The government is "not accustomed to thinking of alliance structures and cooperation," he added.

    NASA will likely miss its 2025 Artemis landing date, with technical and budgetary delays pushing the first crewed landing to later in the decade. China, however, "will put a human crew on the Moon by 2030," Cheng said.
    "If that is their intent, then it will happen."

    Communication could be particularly important on the lunar surface because China and the U.S. are both planning to land missions in the same part of
    the Moon, at the lunar south pole. While those initial landing zones will likely be widely separated, future missions could lead to new questions
    about space traffic management, communications satellites and even the
    primary language used in those activities at the Moon.

    The Big Bang Theory Antenna Lives On

    An antenna that holds an important place in scientific history sits on a
    small parcel of land on Crawford Hill in Holmdel Township, New Jersey.

    The antenna is known as the Holmdel Horn Antenna, and it was built in 1959
    by Bell Labs (now Nokia Bell Labs) researchers. It was originally designed
    to bounce radio signals off of reflective satellite balloons for
    long-distance communication. It worked, and the Holmdel Horn Antenna was no longer needed.

    Two Bell Labs astronomer employees, Arno A. Penzias and Robert W. Wilson, received permission in 1965 to use the antenna to search for radio transmissions in outer space. They pointed the antenna toward what was considered a quiet area, but what they discovered was anything but quiet.
    They discovered Cosmic Microwave Background radiation, which provided
    evidence for the Big Bang Theory.

    Now, there is a historical marker at the site, but there has been some
    dispute as to who owns the antenna and surrounding land. In mid-June 2023,
    the Holmdel Township Committee voted unanimously to approve resolutions
    that will begin the process of acquiring two of the three parcels that make
    up the Crawford Hill property. The township committee is leaving the third parcel to be part of the redevelopment toward preserving Crawford Hill as a public park to celebrate the horn antenna's place in scientific history.

    Changes to AMSAT-NA TLE Distribution for 2023 30 June

    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

    This week there are no additions or deletions to the weekly AMSAT-NA TLE distribution.

    Amateurs and others around the world may listen in on contacts between
    amateurs operating in schools and allowing students to interact with
    astronauts and cosmonauts aboard the International Space Station. The
    downlink frequency on which to listen is 145.800 MHz worldwide.

    Mohammad Bin Rashid Space Centre, Dubai, UAE, direct via A68MBR. The ISS callsign was OR4ISS, and the crewmember was Sultan Al Neyadi, KI5VTV. The
    ARISS mentor was ON6TI. Contact was successful: Thursday, 2023-06-22
    08:38:52 UTC with 51 degrees maximum elevation. Congratulations to the
    Mohammad Bin Rashid Space Centre students, Sultan Al Neyadi KI5VTV, and
    mentor ON6TI!

    Due to summer school holidays, no contacts currently scheduled.

    The crossband repeater continues to be active (145.990 MHz up {PL 67} &
    437.800 MHz down). If any crewmember is so inclined, all they have to do is pick up the microphone, raise the volume up, and talk on the crossband repeater. So give a listen, you just never know.

    The packet system is also active (145.825 MHz up & down).

    As always, if there is an EVA, a docking, or an undocking; the ARISS radios
    are turned off as part of the safety protocol.

    Note, all times are approximate. It is recommended that you do your own orbital prediction or start listening about 10 minutes before the listed

    Upcoming Satellite Operations

    To include your satellite roving plans in the AMSAT News Service Weekly bulletins, send them to Ian, K5ZM at k5zm (at) comcast (dot) net at least a couple of weeks in advance. Upcoming satellite operations are updated
    weekly on the AMSAT Upcoming Satellite Operations page but may expire
    before the next AMSAT News Service bulletin is released. You can watch for
    the latest roving information to become available at https://www.amsat.org/satellite-info/upcoming-satellite-operations/

    Mitch Ahrenstorff, AD0HJ, has a satellite rove planned over the July 4th weekend in the hopes of joining the exclusive Western Roving Coalition.
    Look for him to activate Montana grid squares DN57, DN67, DN77, DN87, DN97, DN56, DN66, DN76, DN86, DN96, DN55, DN65, AND DN64 between June 30th and
    July 3rd. Planned passes are available at http://hams.at OR on Twitter @GridMasterHeat

    Jim DeLoach, WU0I, with XYL, KK6DZS, just started a 6-week road trip. Along
    the way, they hope to activate a number of rarer grid squares on the FM
    birds on the way to the Four-Corners area of the Southwest from the
    Michigan UP, through Western Ontario, Manitoba, Saskatchewan, Alberta, and Idaho.

    A growing number of satellite rovers are currently engaged in sharing their grid square activations on https://hams.at. By visiting the website, you
    gain easy access to comprehensive information about the operators
    responsible for activating specific grid squares. Additionally, you have
    the ability to assess the match score between yourself and a particular
    rover for a given pass, while also being able to identify the upcoming satellite passes that are accessible from your location.

    Satellite Shorts From All Over

    +The 15th annual 13 Colonies Special Event will take place July 1 - July 7, 2023, and will include satellite operations, primarily on the linear transponder satellites. All 13 colonies are covered by satops this year
    making a clean sweep possible. See http://www.13colonies.us/ for more
    details. (ANS thanks Ant Lefebvre, NU1U, for the above information)

    + In a highly anticipated and globally coordinated announcement on
    Wednesday, June 28, teams of scientists worldwide reported the discovery of
    the "low pitch hum" of cosmic waves flowing through the Milky Way. While astronomers don't definitively know what's causing the hum, the detected
    signal is "compelling evidence" and consistent with theoretical
    expectations of gravitational waves emerging from pairs of "the most
    massive black holes in the entire universe" weighing as much as billions of suns. (ANS thanks Space.com for the above information)

    + ESA announced the Zero Debris Charter at the Paris Air Show, by which
    they mean that they will figure out their plans for generating zero space debris (hopefully) by the end of the year, to be implemented by 2030. (ANS thanks The Orbital Index for the above information)

    + Gamma Ray Burst 221009A, a supernova with its energetic jet pointed
    directly at Earth, was first observed last October. While it was 2.4
    billion light-years away, it still managed to disturb Earth’s ionos
    produced 18 tera-electron-volt photons, and saturated spacecraft X-ray and gamma-ray sensors. This explosion is now referred to as the BOAT (Brightest
    of All Time) and is thought to be a once-in-a-10,000-year occurrence. It
    also illuminated dust clouds in our galaxy, allowing their distances and properties to be measured with unprecedented accuracy. (ANS thanks The
    Orbital Index for the above information)

    + Richard Branson’s Virgin Galactic launched its first commercial s
    flight Thursday, June 29, sending three Italian researchers, two company
    pilots and an astronaut trainer on a high-speed thrill ride to the edge of space aboard a winged rocketplane. (ANS thanks SpaceflightNow for the above information)

    + A SpaceX Dragon cargo spacecraft left the International Space Station on Thursday, June 29, to return to Earth. The spacecraft is carrying more than 3,600 pounds of equipment, supplies and scientific experiments, some of
    which have been on the space station for nearly six years and which had
    their final in-orbit tests completed earlier this year. (ANS thanks Space
    Daily for the above information)

    + The European Space Agency’s Euclid spacecraft launched on July 1
    Cape Canaveral Space Force Station. Euclid features a telescope 1.2 meters across equipped with a camera operating at visible wavelengths and a near-infrared spectrometer and photometer. The two-ton spacecraft will
    operate at the Earth-sun L-2 point also used by the James Webb Space
    Telescope 1.5 million kilometers from Earth, generating the largest and
    most accurate 3-D map of the universe to date. Astronomers hope that
    Euclid’s observations will shed light on two of the biggest mysteri
    es in
    cosmology: the nature of both dark energy and dark matter that, combined, comprise 95% of the universe. (ANS thanks SpaceNews for the above
