*ARISS News Release No. 25-07* *Dave Jordan, AA4KN * *ARISS PR* *dave.jordan(a)ariss-usa.org <dave.jordan(a)ariss-usa.org>* *FOR IMMEDIATE RELEASE* *Fram2Ham SSTV Simulation on ISS* February 1, 2025—The ARISS international team has devised a proficiency training SSTV (Slow Scan Television) exercise to prepare all SSTV image receivers for what to expect on the upcoming Fram2 mission. *Fram2 Mission and Fram2Ham Payload Overview* Fram2 is a pioneering private astronaut mission, the first to fly astronauts over the North and South poles. Fram2 will give the four on-board astronauts unprecedented first views of the polar regions from space. While astronauts on the ISS can see a large portion of the Earth, it is not possible to see these upper regions of Earth from the ISS. Fram2 is planned to be launched no earlier than March 1, 2025 and is planning a 3 day mission with an optional 2 day extension. The amateur radio experimental payload on Fram2, called Fram2Ham, is also pioneering in nature. It represents the first use of human spaceflight amateur (ham) radio in polar orbit and the first amateur radio transmissions from a SpaceX Dragon capsule. Fram2Ham operations are being performed by private astronaut Rabea Rogge, amateur radio callsigns LB9NJ (Norway) and KD3AID (USA). Fram2Ham will transmit Slow Scan Television (SSTV) picture images from space to radio receivers on the ground as part of a high school and university student competition. These SSTV images can also be received by radio enthusiasts (hams, educators, and youth) worldwide and posted to the ARISS SSTV Gallery—but with a twist. Images posted will not be shown until after the Fram2 mission. These operations support the youth SSTV competition, where they are to acquire several SSTV “Puzzle Pieces,” assemble the puzzle, determine the polar location, and answer questions related to that location. For more information on the Fram2 mission and for youth organizations interested in participating in the Fram2Ham SSTV competition, see: f2.com and Fram2Ham.com. ARISS also has a Fram2 tab on its website www.ariss.org. *Fram2Ham SSTV Simulation on ISS* The ARISS international team is planning an SSTV event to help all participating to be as proficient as possible in acquiring images from Fram2Ham and submitting them in the SSTV gallery. Like previous SSTV events, ARISS will provide special commemorative certificates for those who upload images to the gallery. Certificates will be delivered after the completion of both the Fram2 simulation event and the Fram2 mission. *SSTV Simulation details* ARISS radio: The Kenwood TM-D710GA transmitter will be set to low power (5 watts vs. 25 watts for previous SSTV events). This is to simulate the challenges and unknowns of a new radio system on a Dragon capsule that might be in an unfavorable attitude in some parts of the mission flight path. Operations Frequency: 437.550 MHz. Using the SSTV (public downlink) planned for Fram2Ham, ground users can practice the more challenging 70 cm doppler correction. SSTV Mode: PD120. The longer image capture for this simulation (120 seconds, vs. 36 seconds for Fram2Ham’s Robot 36 SSTV mode) will allow ground users to hone their signal polarization switching skills (manually and electronically) as well as precise antenna pointing. Operations Duration: February 13 (World Radio Day) to February 17, 2025. This long duration, over a weekend, will allow users multiple passes to practice, learn lessons, make corrections, and try again. SSTV Gallery Site: https://ariss-usa.org/ARISS_SSTV/ *Summary * Fram2Ham will be an exciting, first of its kind, mission and the first ham radio operations in a space capsule. Fram2Ham signal propagation will not be fully understood until the mission starts and ground users report their results. Since variations of antenna orientation are expected during the mission, SSTV downlinked signals might be heard to the right or left of the flight path, during the ascending or descending part of the flight path or beamed to space instead of to Earth. In addition, Fram2 will be a short, 3-day, mission duration, with maybe 1-2 higher elevation passes per day and with a startup several hours after launch and shutdown several hours before reentry. These challenges require operating proficiency and the use of the best attainable radio station. Our Fram2Ham pioneers need to be prepared and proficient. Are you up for the challenge? *About ARISS:* Amateur Radio on the International Space Station (ARISS) is a cooperative venture of international amateur radio societies and the space agencies that support the ISS. In the United States, sponsors are the American Radio Relay League (ARRL), Amateur Radio Digital Communications (ARDC), Radio Amateur Satellite Corporation (AMSAT), NASA’s Space Communications and Navigation program (SCaN) and the ISS National Lab—Space Station Explorers. The primary goal of ARISS is to promote exploration of science, technology, engineering, the arts, and mathematics topics. ARISS does this by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students. Before and during these radio contacts, students, educators, parents, and communities take part in hands-on learning activities tied to space, space technologies, and amateur radio.
