Astronauts Engage in Voice Contacts from International Space Station

Amateur radio enthusiasts were thrilled as astronauts aboard the International Space Station (ISS) engaged in voice contacts as NA1SS over the period of May 25-29. The astronauts, John Shoffner, KO4MJC and Woody Hoburg, KB3HTZ, provided an opportunity for amateur radio operators to establish contact with the orbiting space station.

The Amateur Radio on the ISS (ARISS) program facilitated these voice contacts, allowing radio operators to communicate with the astronauts onboard the ISS. As the news spread on social media, amateur radio operators shared their excitement about making successful contacts with the astronauts.

Hams from different parts of the world, including Europe, the United States, and the United Kingdom, shared their experiences of communicating with the ISS crew on Twitter. The astronauts were actively seeking information about the location of each station, showing a keen interest in the diverse range of contacts they were making.

The ARISS program encourages participants to submit QSL cards to commemorate their successful contacts. These cards serve as proof of communication with the International Space Station. The ARISS website provides information on how to send in QSL cards and further details about the program. The QSL contacts are regional so find the proper one at:

For many radio operators, making contact with the International Space Station is a memorable experience. The ability to communicate with astronauts orbiting the Earth, even if only for a brief moment, is a testament to the power of amateur radio and its ability to connect people across vast distances.

As the ARISS program continues to facilitate these voice contacts, space and amateur radio enthusiasts eagerly await further opportunities to establish communication with the astronauts onboard the ISS. The chance to exchange greetings and information with those who reside in space remains a unique experience that showcases the wonders of technology and human ingenuity.

Operators interested in attempting a contact with the ISS crew, should set the downlink frequency to 437.800 MHz FM and listen for activity. The uplink frequency is 145.990 MHz FM with a PL tone of 67 Hz. The ARISS website and the AMSAT status page provide information on the ISS crew’s radio activities. See for details.

New Record Set with Seventeen People in Earth Orbit Simultaneously

In a remarkable achievement, the number of individuals in Earth orbit has reached a new record high. On May 30, 2023, a total of seventeen people from five different countries were in Earth orbit.

The population in orbit skyrocketed with the launch of China’s Shenzhou 16 mission, which took place on May 29 at 9:31 p.m. EDT. This three-person mission propelled the overall count to a new record. Previously, the record stood at fourteen people, achieved during the privately funded Inspiration4 mission in September 2021.

The current count consists of four crews representing various space agencies and private ventures. The first crew, Shenzhou 16, consists of Chinese taikonauts Jing Haipeng, Zhu Yangzhu, and Gui Haichao, who have joined the astronauts already aboard China’s Tiangong space station. This mission contributes three members to the total count.

The second crew, Shenzhou 15, consists of Fei Junlong, Deng Qingming, and Zhang Lu. They have been residing aboard the Tiangong space station since November 2022 and are expected to return to Earth in early June. Their presence adds another three individuals to the record-breaking count.

The third crew, Expedition 69, comprises seven members from different countries. It includes cosmonauts Sergey Prokopyev, Dmitry Petelin, and Andrey Fedyaev from Russia’s Roscosmos, as well as astronauts Frank Rubio, Stephen Bowen, KI5BKB, and Warren “Woody” Hoburg, KB3HTZ, from NASA. Emirati astronaut Sultan AlNeyadi, KI5VTV, of the United Arab Emirates (UAE) also joins them. These individuals are currently on the International Space Station (ISS), contributing significantly to the total population in orbit.

The fourth crew, Axiom-2, is composed of Axiom Space astronaut Peggy Whitson, private astronaut John Shoffner, KO4MJC, and Saudi Arabian astronauts Ali AlQarni, 7Z1AJ, and Rayyanah Barnawi, 7Z1RB. They departed the ISS aboard SpaceX’s Crew Dragon “Freedom” on May 30. The Axiom-2 crew splashed down off the Florida panhandle near Panama City around 11 p.m. on May 30, reducing the count to thirteen people.

Interestingly, the current record-breaking count coincides with another milestone. Barnawi, a member of the Ax-2 mission, became the 600th person to enter Earth orbit. She also holds the distinction of being the first Saudi woman in space, as she launched alongside her crew on May 21.

Although the record stands at seventeen people in Earth orbit, it’s worth noting that a recent record for the most people in space (not just in Earth orbit) was set briefly. For approximately five minutes, a total of twenty individuals were off the planet. This record occurred when the six members of Virgin Galactic’s Unity 25 SpaceShipTwo crew embarked on a suborbital spaceflight, coinciding with three Chinese taikonauts residing aboard Tiangong and eleven astronauts, cosmonauts, and spaceflight participants aboard the International Space Station.

The previous record for the most people in space simultaneously was set during Blue Origin’s New Shepard NS-19 suborbital flight on December 11, 2021, when there were briefly nineteen individuals off Earth.

Since the year 2000, there has been an unbroken presence of humans in space, starting with the first crew to inhabit the International Space Station. China’s completion of its three-module Tiangong space station last year marks another significant milestone. The Shenzhou 16 crew represents the station’s fifth contingent since 2021.

Changes to AMSAT-NA TLE Distribution for June 2

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 Thursday evenings around 2300 UTC, or more frequently if new high interest satellites are launched. More information may be found at

The following satellite has decayed from orbit and has been removed from this week’s AMSAT-NA TLE distribution:

NUDATSat NORAD Cat ID 42787 (decayed form orbit on 28 MAY 2023 per Space-Track).

Another Delay For Boeing’s Starliner Crew Capsule

Boeing and NASA officials said Thursday, June 1, that the first launch of astronauts on Boeing’s delay-prone Starliner crew capsule won’t happen in July after engineers recently discovered a problem with the spacecraft’s parachute system and identified flammable tape around wiring harnesses inside the vehicle.

The technical problems, which escaped detection for years, dealt another setback for Boeing’s Starliner program, already running years behind schedule after a series of issues with software, valves, and other parts of the spacecraft.

NASA wants Boeing’s Starliner to come online as a second U.S. crew transportation provider for the space station. Russia’s Soyuz spacecraft, which was the sole vehicle to carry crews to the space station for nine years, is currently NASA’s backup if SpaceX’s Falcon 9 rocket or Crew Dragon spacecraft suffer significant delays or failures.

NASA astronauts Butch Wilmore and Suni Williams, KD5PLB, were in the final stages of training for launch on the first Starliner crew mission, called the Crew Flight Test, as soon as July 21. They were slated to lift off from Cape Canaveral on a United Launch Alliance Atlas 5 rocket and fly to the space station on the Starliner spacecraft for a test flight lasting about one week, then return to Earth for a parachute-assisted landing in New Mexico.

That would have paved the way for Boeing to start launching regular NASA crew rotation flights to the space station on a schedule of about once per year beginning in 2024.

Boeing and NASA officials did not provide an estimate for when engineers might resolve the newest technical problems on the Starliner spacecraft.

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 time.

Hamfests, Conventions, Maker Faires, and Other Events

AMSAT Ambassadors provide presentations, demonstrate communicating through amateur satellites, and host information tables at club meetings, hamfests, conventions, maker faires, and other events.

+ AMSAT Space Symposium and Annual General Meeting
October 20-21, 2013
Dallas, Texas

AMSAT Ambassador Clint Bradford, K6LCS, says,
“Think a 75-minute presentation on “working the easy satellites” would be appropriate for your club or event? Let me know by emailing me at k6lcsclint (at) gmail (dot) com or calling me at 909-999-SATS (7287)!”

Clint has NEVER given the exact same show twice: EACH of the 150+ presentations so far has been customized/tailored to their audiences. An email message received after a recent presentation:

“I really enjoyed Clint’s presentation last night. The fact that he had taken the time to research and know something about his audience and welcomed interaction made it very informative and enjoyable. This was a refreshing change from many canned YouTube presentations I’ve tried to watch, which were poorly done, fuzzy video or muddy audio, or a badly prepared presenter stumbling his way through, with any valuable info lost along the way. Thanks for hooking this one up.”
