    AMSAT-DL Operators Track Mars Probe

    Members of the German AMSAT organization, AMSAT-DL, in cooperation with the Sternwarte Bochum Institute in Bochum, Nordrhein-Westfalen, Germany, have been using the Institute's 20-meter (65.6 foot) diameter dish antenna to listen directly to signals from
    probes in Mars orbit.

    Signals have been copied from Tianwen-1, the Chinese spacecraft currently in Mars orbit, and from EMM/Hope, the Emirates Mars Mission, which is also orbiting Mars. Both spacecraft are transmitting in the 8.4 GHz band.

    Recordings of the signals can be heard on YouTube at https://www.youtube.com/watch?v=413DdMua8ec&feature=emb_imp_woyt and regular updates can be seen by following @amsatdl on Twitter.

    The Bochum Observatory dish was constructed in 1965 as part of the ground support network for the Apollo missions. Weighing in at 140 tons, it is protected from weather by an air dome 40 meters (131 feet) in height. In 2003, amateurs helped renovate some
    of the equipment, adding phase-locked receivers in the 2.3 GHz, 5.8 GHz, and 10.4 GHz amateur bands, as well as an 8.4 GHz receiver. There is also an S-band, 2.4 GHz amateur transmitter running 250 Watts PEP.

    In 2006, the dish was used to copy signals from the Voyager 1 spacecraft at a distance of nearly 15 billion kilometers. Since 2009, AMSAT-DL operators have used the dish regularly to copy NASA/NOAA weather satellites. Also in 2009, the dish was used to
    copy planetary radar echoes bounced off the planet Venus. Since 2001, the dish has copied signals from at least a dozen different deep space probes, including Tianwen-1 and EMM/Hope.

    In the summer of 2002, AMSAT Germany officially began planning and preparing to send its own space probe to the red planet. It is supposed to fly around Mars as a radio relay, take pictures, carry out scientific experiments and deposit a payload on the
    surface of Mars. The goal is to create a probe that can be received on amateur radio frequencies using a 2 to 3 meter parabolic antenna. Images and data would be displayed directly on your own computer with the appropriate software.

    This ambitious plan is a long-term goal of AMSAT-DL, and the work of amateurs tracking the current Mars orbiters at Bochum Institute provides valuable experience toward reaching this goal.

    AMSAT-NA TLE Distribution for February 25, 2021

    Ray Hoad, WA5QGD released updated TLE data on February 25, 2021 and is available for download at:

    Also noted by Ray is that the following satellite has decayed from orbit and has been removed from
    this week's AMSAT-NA TLE Distribution:

    PWSat 2 - NORAD Cat ID 43814 (Decayed 2-23-2021 per Space-Track).

    For newcomers wondering about TLE's, they are two-line element set (TLE) is a data format encoding a list of orbital elements of an Earth-orbiting object for a given point in time, the epoch. Using a suitable prediction formula, the state (position and
    velocity) at any point in the past or future can be estimated to some accuracy. For more information, see the Wikipedia article at:

    IARU Coordinates Frequencies for Two New Satellites

    The International Amateur Radio Union assigned coordinated frequencies for two upcoming Amateur Radio Satellites.

    - FSI-SAT1
    The Institute of Future Science at the Happy Science University in Japan will fly FSI-SAT1, a 1U CubeSat carrying a SSTV camera for transmission on an FM downlink, multispectral wavelength cameras and reception equipment for an infra-red uplink. A UHF
    downlink at 437.175 will operate CW, analog SSTV, 9k6 GMSK and 1k2 AFSK. A sun synchronous orbit at 500/560 km is planned.

    - JAGSAT
    The University of Alabama will fly JAGSAT, a 2U CubeSat designed to measure plasma electron density in the upper F layer of the ionosphere between 400-800 km. The mission will be used to study space weather monitoring, specifically to understand and
    predict the effects of RF scintillation on Amateur Radio and other communication signals. A UHF downlink has been coordinated at 437.325 using 9k6 2-GFSK modulation with AX.25. JAGSAT is planned to be deployed from the ISS with other ELANA-37 missions
    in the second quarter of 2022.

    More information on both satellites is available at: http://www.amsat.org.uk/iaru/

    23cm Band in the Spotlight with Regulators

    The Chair of IARU Region 1 Spectrum Affairs, Barry Lewis G4SJH, reports on the meeting of the ITU-R Working Party 4C (WP4C) on February 15-19 which discussed the amateur radio allocation at 1240-1300 MHz.

    On the IARU Region 1 site he writes:

    During the week February 15–19, the preparatory work for WRC-23 agenda item 9.1b continued in ITU-R Working Party 4C (WP4C). The WRC agenda item has initiated technical studies on coexistence between the radio navigation satellite service (RNSS) and
    the amateur services in the 23cm band. As usual, the IARU participated in the meeting and delivered key information on amateur activities in this important microwave band. This information is vital to ensure the amateur services are realistically
    represented in the studies as they move forward.

    It remains vital that national amateur communities present their views on the importance of this band to their national regulators in a consolidated and consistent manner.

    To assist with this the IARU-R1 is developing supporting material that member societies can refer to when addressing the topic with their national regulator.

    The work on this topic will continue throughout the year and beyond both in ITU-R and in the regional telecommunications organizations and the IARU is committed to ensure every organization understands the amateur position on this important microwave

    The Perseverance Parachute's Secret Code

    A secret coded message was hidden on the gigantic parachute used to land the Perseverance rover safely on the surface on Mars. And no, it wasn't a clandestine message to the Martians. It was a message of inspiration for us humans. But it also came as a

    During a news briefing on February 22, Allen Chen, the entry, descent and landing lead for the mission revealed there was a secret message in the parachute.

    "In addition to enabling incredible science, we hope our efforts in our engineering can inspire others," he said. "Sometimes we leave messages in our work for others to find for that purpose, so we invite you all to give it a shot and show your work."

    Puzzle lovers around the world quickly went to work, and it didn't take long.

    Adam Steltzner, Perseverance's chief engineer, confirmed "the internet" had cracked the code late Monday night on Twitter.

    Hidden in the 70-foot (21-meter) parachute's red and white pattern was a binary code with the phrase "Dare mighty things" - a famous expression from President Theodore Roosevelt, espoused by those who work at the Jet Propulsion Laboratory. The outer
    rings of the pattern also feature GPS coordinates for JPL's offices in Pasadena, California: 34°11'58" N 118°10'31" W.

    Chen later confirmed on Twitter that the code was the brain child of systems engineer Ian Clark, who helped conduct tests of the supersonic parachute, as well as performing several other tasks for the Perseverance rover team. Clark is a crossword
    hobbyist, and said only about six people knew about the coded message before this week.

    Chen expressed how grateful he is for the ability to work with such creative people at JPL. "It's a feeling of being very fortunate at the end… that I get to work at a place with people who are both great engineers and great people, and we still get to
    dare mighty things together," he said at Monday's briefing.

    Secret messages on the rovers are not new. The Curiosity rover has holes in its wheels that creates marks in the Mars regolith that spells out "JPL" in Morse Code.

    It was also revealed that Perseverance bears a plaque depicting all five of NASA's Mars rovers in increasing size over the years - reminiscent of the decals on cars that portray the family riding inside.

    Deputy project manager Matt Wallace said more hidden "Easter eggs" should start showing up on Perseverance when more images of the rover itself are taken and beamed back to Earth.

    "Definitely, definitely should keep a good lookout," he said.
