Amateur Radio on the International Space Station (ARISS) announced on April 18, 2014 the US schools/host organizations newly selected for 2024 ARISS contacts. A total of 9 of the submitted
proposals during the recent proposal window have been accepted to move forward in the processes of planning to host a scheduled amateur radio contact with crew on the ISS. The primary goal of the ARISS program is to engage young people in Science, Technology,
Engineering, Arts and Math (STEAM) activities and raise their awareness of space communications, radio communications, space exploration, and related areas of study and career possibilities.
The ARISS program anticipates that NASA will be able to provide scheduling opportunities for the 9 US host organizations during the July – December 2024 time period. They are now at work
starting to implement their 4–6-month education plan which was outlined in their proposal. These STEAM based educational activities help prepare students for their contact as well as create an on-going exploration and interest in aerospace and amateur radio
topics. They are also completing an acceptable equipment plan that demonstrates their ability to execute the ham radio contact. Once their equipment plan is approved by ARISS, the final selected schools/organizations will be scheduled as their availability
and flexibility match up with the scheduling opportunities offered by NASA.
The schools and host organizations are:

Frank Karnauskas, N1UW, AMSAT VP – Development happily reports, “Each year for the past four years of its re-incarnation, the AMSAT President’s Club has picked up speed and becomes a more
important factor in AMSAT’s annual fund raising efforts. The first quarter of the 2024 the President’s Club is off to a great start. With our regular dedicated contributors plus many first-time members, contributions have already raised almost $16,000 in the
first three months of 2024.
“So often, our members think about AMSAT’s having to raise funds for satellite hardware – the costs for electronic components, solar panels, batteries and so on. But, there are many background
costs. A good example is software licenses needed for actual satellite development. The volunteer engineers can often swap licenses so they can limit the number of licenses needed. But, as they draw closer to finalizing drawings for circuit boards, spaceframes
and deployable solar panels, the team can stretch software licenses only so far before work flow becomes handicapped. Some software licenses, even with the best educational or non-profit discounts, easily exceed the $1,000 mark. And, those licenses need to
be renewed on an annual basis.
“The engineering team can always use more electrical and mechanical engineers to move the FOX-PLUS and GOLF programs along. But, being able to leverage the efforts of our current volunteers
with enough software licenses would be a huge plus. Contributions from members of the President’s Club make a big difference in giving the engineering team the tools they need.”
To date, the generous donors members of the 2024 AMSAT President’s Club include:

Given hams’ inherent interest in all things technical, it’s no wonder that the Engineering table at AMSAT’s Hamvention booth is always popular. Not wanting to disappoint our members, Jerry
Buxton, N0JY, AMSAT VP- Engineering and his team are making plans for an informative and entertaining presence. No fewer than ten members of the engineering team will attending this year’s Hamvention.
Probably the most interesting exhibit will be a full-scale model of the GOLF-TEE (Technology Exploration Environment) satellite. The 3-D model printed by team member Tom Karnauskas,
N0UW, gives an interesting look at the challenges that satellite designers face when trying to fit stacks of circuit boards, bundles of batteries, attitude sensing and control systems, and experimental payloads inside a
10cm x 10cm x
30cm spaceframe. The model also gives a look at the challenge of adding deployable solar panels to the exterior of the spacecraft. Given the fact that the GOLF program represents AMSAT’s return to Highly Elliptical Orbit (HEO), engineers will no-doubt
be busy answering questions on all facets of the GOLF program.
Engineers will also be on hand to answer questions about the ongoing development of the Fox-Plus series of satellites. Recognizing the success of the original Fox series as an entry level
introduction to amateur satellites, the engineers working the Fox-Plus birds are committed to improving on the original concept and setting the stage for future capabilities for these Low Earth Orbit (LEO) satellites.
For those interested in a look even further into the future, engineers working the ASCENT program will also be present. ASCENT, meaning, Advanced Satellite Communication and Exploration
of New Technology, is a “sandbox” for future satellite communications and related systems to be explored and pursued for eventual flight use. A radiation-tolerant internal-housekeeping-unit (RT-IHU), software defined radio (SDR)
methods, and a 10 GHz PA design ideas are some ASCENT projects that will fly on GOLF-TEE. Engineers at the table can also discuss other ASCENT projects in the works such as a slow-scan television (SSTV) payload, a packet repeater payload and propulsion systems
suitable for CubeSat operation.

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/.
The following satellites have been removed from this week’s AMSAT-NA TLE distribution:

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 time.
