Fram2 Mission With Amateur Radio Payload Scheduled to Launch March 31st
Fram2 is currently scheduled to launch on April 1, 2025 at 01:46:50 UTC
(March 31, 2025 at 21:46:50 EDT).
The Fram2 mission is set to become the first human space flight in polar
orbit - flying over the North and South poles. Named after the famo
us polar
exploration ship Fram, which completed voyages to both the Arctic and
Antarctica, we want to showcase pioneering spirit, wonder and technological
innovation through the ages. The SpaceX Falcon 9 rocket will launch four
astronauts from Europe and Australia into orbit for 3-5 days, target. On
board the Dragon spacecraft are mission commander Chun Wang of Malta,
vehicle commander Jannicke Mikkelsen of Norway, pilot Rabea Rogge of
Germany and mission specialist Eric Philips of Australia. During the Fram2
mission Rabea Rogge, LB9NJ (Norway) and KD3AID (USA), will be
operating the onboard
amateur (ham) radio system <https://fram2ham.com/> sending SSTV images as
part of a high school and university student competition. These SSTV images
will also be available to be received by the general public during the
mission. Read more about Fram2 and its crew here: f2.com
SSTV transmissions will be transmitted on 437.550 MHz FM using Robot36.
TLEs for the mission are available from https://www.ariss.org/keps.html
Provisional elements for the upcoming Fram2Ham mission have also been added
t0 the AMSAT TLE distributions courtesy of ARISS, and will be updated when
the SpaceX Dragon vehicle attains orbit. Updates will be found at
www.amsat.org/tle/dailytle.txt as appropriate. The mission has also been
added to the AMSAT Satellite Status <https://amsat.org/status/> p[age for
reports
Anyone may submit images to the gallery on the
https://ariss-usa.org/ARISS_SSTV/submit.php page along with information
about when and where the image was received.
Please note that because the Fram2Ham event is a competition, all submitted
images will be held in a queue not available for viewing until after the
competition judges have had a chance to make their decisions. After the
winners have been announced, the Fram2Ham images will be available for
viewing the same as all the other ISS SSTV campaign images. Teams and
members of the general public are asked to *not* distribute copies of their
received images to social media until after the winners of the competition
have been announced.

GridMasterMap Satellite Top 100 Rovers April 2025 Rankings
The April 2025 rankings for the Top 100 Rovers (Mixed LEO/MEO/GEO) in
satellite operations, as determined by @GridMasterMap
<https://x.com/GridMasterMap> on Twitter, has been released. The ranking is
determined by the number of grids and DXCC entities activated, taking into
account only those grids where a minimum number of QSOs logged on the
gridmaster.fr website have been validated by a third party. Grid numbers do
not directly reflect the exact number of activations. Satellite operators
are encouraged to upload their LoTW satellite contacts to
https://gridmaster.fr in order to provide more accurate data.

Changes to AMSAT TLE Distribution for March 28, 2025
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 daily in the first hour of the UTC day. New bulletin
files will be posted immediately after reliable elements become available
for new amateur satellites. More information may be found at
https://www.amsat.org/keplerian-elements-resources/
<https://www.amsat.org/keplerian-elements-resources/>.
The following satellite has been removed from this week's AMSAT TLE
distribution:
KSU-Cubesat NORAD Cat ID 47954 Decayed from orbit on or about 21 March 202
5
Provisional elements for the upcoming Fram2Ham mission have also been added
courtesy of ARISS, and will be updated when the SpaceX Dragon vehicle
attains orbit. Predictions based on these elements will be invalid if the
launch is delayed past the planned 01 April 2025 03:20 UTC liftoff or if
launch vehicle performance is off nominal. Updates will be found at
www.amsat.org/tle/dailytle.txt as appropriate.

Many times a school may make a last minute decision to do a Livestream or
run into a last minute glitch requiring a change of the URL but we at ARISS
may not get the URL in time for publication. You can always check
https://live.ariss.org/ to see if a school is Livestreaming.
As always, if there is an EVA, a docking, or an undocking; the ARISS radios
are turned off as part of the safety protocol.
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.
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.
The latest information on the operation mode can be found at
https://www.ariss.org/current-status-of-iss-stations.html
