2023 AMSAT Symposium Keynote Speakers Announced
Bob Twiggs, KE6QMD, considered to be the âfatherâ of the CubeSat form factor, will be a keynote speaker at the 41st Annual AMSAT Space Symposium and Annual General Meeting
banquet.
Bob is a retired professor of Astronautics and Space Science at Morehead State University. He is responsible, along with Jordi Puig-Suari of California Polytechnic State University,
for co-inventing the CubeSat reference design for miniaturized satellites which became an industry standard for design and deployment of the satellites.
Twiggs earned a Bachelor of Science in Electrical and Electronics Engineering from the University of Idaho in 1961 and a Master of Science in Electrical Engineering with a
concentration in microwave devices from Stanford University in 1964.
From 1985 to 1994, Twiggs was the director of the Weber State University Center for Aerospace Technology. He served as a consulting professor in the Stanford University Department
of Aeronautics and Astronautics from 1994 to 2008. At Stanford, he established the Space Systems Development Laboratory. Bob Twiggs became a professor at Morehead State University in 2009 in an effort to push the PocketQube standard leveraging the university's
large aperture (21m) space tracking system, and to help develop a space economy in the state of Kentucky.
In 2019, Twiggs designed and proposed another smaller, simpler satellite form factor called ThinSat which could enable high school students to design and build satellites.
Joining Bob in the presentation will be Nick Pugh, K5QXJ. A native of Lafayette, Louisiana, Nick is credited with establishing the first microwave loop in the Gulf of Mexico
just two years after his graduation from University of Southwestern Louisiana (now the University of Louisiana at Lafayette). His pioneering leadership with telecommunications technology in and around the Gulf of Mexico over the years has spurred regional
economic development.
Nick is also a longtime community volunteer. He directed University of Louisiana Lafayetteâs successful effort to become the first college team in Louisiana to build and launch
satellites. He also advised the David Thibodaux STEM Magnet Academyâs high school student team, which placed a biological experiment on the International Space Station. Nick is also a member of the Acadiana Area Radio Association and the Lafayette Computer
Club, and a founding member of Acadiana Open Channel.
Nick has served as chair of Habitat for Humanity Lafayette. He was a member of Leadership Lafayette Class XXVII and is a 1998 graduate of Harvardâs Owner/President Management

Russian Soyuz MS-24 Launches Crew to International Space Station
Russian spacecraft Soyuz MS-24, carrying two Russian cosmonauts and a U.S. astronaut, successfully blasted off from the Baikonur Cosmodrome in Kazakhstan on Friday, September
15th, with live TV footage capturing the launch. This mission marked the 85th launch of the Soyuz 2.1a in 2023 and the 6th launch from the Baikonur Cosmodrome in the same year, contributing to the 149th orbital launch attempt of 2023.
The Soyuz MS-24 mission, also known as Expedition 70/71, had initially been scheduled for March 16, 2023. However, due to technical issues with the docked Soyuz MS-22 spacecraft,
the crewed mission was reassigned to Soyuz MS-24. The spacecraft, designated Soyuz MS-24, carried American astronaut Loral O'Hara along with Russian cosmonauts Oleg Kononenko and Nikolai Chub.
The mission launched under the auspices of the Russian space agency, ROSCOSMOS, utilizing the Soyuz 2.1a launch vehicle. The lift-off took place from Launch Complex 31/6 at
the Baikonur Cosmodrome. The spacecraft's destination was the International Space Station (ISS), situated in a low Earth orbit approximately 400 kilometers above Earth's surface at a 51.66° inclination.
The crew of Soyuz MS-24, upon reaching the ISS, would join the existing station crew members, which included NASA astronauts Frank Rubio and Jasmin Moghbeli, KI5WSL, Russian
cosmonauts Dmitry Petelin, Konstantin Borisov, Sergei Prokopyev, as well as Denmark's Andreas Mogensen, KG5GCZ, and Japan's Satoshi Furukawa, KE5DAW.
The Soyuz MS-24 crew was composed of Commander Oleg Kononenko, Flight Engineer 1 Nikolai Chub from ROSCOSMOS, and Flight Engineer 2 Loral O'Hara from NASA. Commander Oleg Kononenko,
RN3DX, had previously completed four spaceflights and accumulated 916 days in space, exceeding the previous record of 878 days held by Gennady Padalka.
Nikolai Chub, on the other hand, was embarking on his first journey to space as Flight Engineer 1, having been selected as a Roscosmos cosmonaut in 2012. Loral O'Hara, KI5TOM,
Flight Engineer 2, was an astronaut candidate with NASA's 2017 Astronaut Candidate Class, making Soyuz MS-24 her maiden spaceflight.
Soyuz, introduced in 1966, has long served as the multi-use medium-lift launch vehicle for the Soviet/Russian space program. Its versatile capabilities encompass launching
civilian and military satellites, cargo, and crewed missions to the ISS. The Soyuz-2 rocket stands approximately 46.3 meters tall, with a diameter of 2.95 meters, and a total lift-off mass of about 312,000 kilograms. Its payload capacity to low-Earth orbit
ranges from 6,600 to 7,400 kilograms.
The Soyuz MS spacecraft, in this case, Soyuz MS-24, is the latest iteration of Russia's renowned three-person spacecraft. Although its external appearance has remained relatively
consistent since its first flight in the 1960s, internal systems and capabilities have been modernized over time.
The spacecraft consists of three sections: the orbital module, the descent module, and the service module. The orbital module is where the crew primarily resides while in orbit
and docks with the ISS. The descent module is the section that returns to Earth intact, carrying the crew during launch and reentry. The service module houses the main engine for orbital maneuvers, thrusters for docking, and life support systems.
The Soyuz MS-24 mission docked with the ISS approximately three hours and 15 minutes after liftoff, adding to the station's international crew and enabling further scientific
research in the unique environment of space.

Imperial College Develops Miniature Rocket Thruster for CubeSats
Researchers at Imperial College have designed a miniature rocket thruster so small that it can only be fabricated using techniques originally intended for creating silicon
microchips. Named the "Iridium Catalysed Electrolysis CubeSat Thruster" or ICE-Cube Thruster, this innovation holds the promise of revolutionizing the propulsion systems for small satellites, particularly CubeSats, by offering a compact, efficient, and eco-friendly
solution.
Satellites weighing under 10 kilograms, constituting approximately 90% of today's satellite launches, present a unique set of challenges when it comes to developing components
for them. Among the most critical challenges is designing rocket thrusters tailored to the limitations of CubeSats. These thrusters must not only be diminutive in size but also uncomplicated, unpressurized, low-power, and devoid of toxic materials.
Funded by the European Space Agency (ESA), the ICE-Cube Thruster meets these stringent criteria, with its primary attribute being its diminutive size. The entire thruster chip,
comparable in length to a human fingernail, features a combustion chamber and nozzle measuring a mere 1 millimeter. It demands a mere 20 watts of electric current to operate. A test campaign achieved 1.25 millinewtons of thrust at a specific impulse of 185
seconds. To provide a sense of scale, this thrust output is roughly half a billion times less powerful than the engines used on the Space Shuttle.
However, the true innovation of the ICE-Cube Thruster lies in its propellant choice, ordinary water. Water, known for its non-explosive and non-flammable properties, is utilized
as the propellant of choice. An onboard electric current induces electrolysis within the thruster, breaking down the water into hydrogen and oxygen. These gases are then fed into the combustion chamber, where they ignite, producing the necessary thrust to
maneuver the CubeSat.
This utilization of water as propellant not only aligns with sustainability goals but also reduces overall payload requirements. The absence of the need for pressurization
in storing the propellant streamlines storage and handling systems, making them lighter and more straightforward. However, the challenge lay in fabricating the combustion chamber and nozzle for the thruster, a task that required adopting a technique akin to
microelectronics. The researchers utilized Micro-Electrical Mechanical Systems (MEMS) techniques, typically used for machining silicon wafers for processors to sub-micrometer tolerances.
The successful testing of the ICE-Cube Thruster was conducted through an ESA General Support Technology Programme De-Risk activity, validating its feasibility in a controlled
laboratory environment. The data acquired during this testing phase will serve as a vital guide in the development of a flight-representative "Engineering Model" of the propulsion system, including the electrolyser. This development is slated to be led by
URA Thrusters in collaboration with Imperial College.

GOES-U Successfully Completes Environmental Testing for 2024 Launch
NOAA's upcoming satellite, GOES-U, the final addition to the GOES-R Series of advanced geostationary satellites, has completed a rigorous battery of tests to ensure its readiness
for the challenges of launch and its mission in space. The year-long testing process concluded with GOES-U proving its resilience to the harsh conditions of space, situated 22,236 miles above Earth.
The testing regimen, which commenced in November 2022, involved subjecting GOES-U to extreme temperatures ranging from a scorching 188 degrees Fahrenheit (87 degrees Celsius)
to a bone-chilling minus 67 degrees Fahrenheit (minus 55 degrees Celsius). This thermal vacuum testing aimed to simulate the harsh temperature fluctuations during both launch and its mission in the space environment.
Following this, in February 2023, the satellite underwent vibration testing to ensure its structural integrity during the stresses of launch. It then faced the intense sounds
of 138.4 decibels during acoustic testing, replicating the noise levels experienced during launch.
March 2023 witnessed the successful completion of shock testing, confirming GOES-U's ability to withstand the separation from the launch vehicle and the deployment of its solar
panels. Subsequently, in August 2023, electromagnetic interference and compatibility (EMI/EMC) testing ensured that the satellite's operations would remain unaffected by various forms of electromagnetic radiation.
Notably, GOES-U's large five-panel solar array, initially folded during launch, was verified to deploy correctly upon reaching geostationary orbit. These solar panels will
serve as the primary source of power, converting sunlight into electricity to operate the satellite's instruments, computers, data processors, sensors, and telecommunications equipment.
The exhaustive testing program was conducted at Lockheed Martin's facility in Littleton, Colorado, where GOES-U was built. Simultaneously, as the satellite was being prepared
for the rigors of launch and space, the GOES-U mission operations team engaged in critical rehearsals to test launch procedures and communication systems between the satellite and ground facilities.
These rehearsals encompassed a wide range of scenarios, including normal operations and contingency procedures in case of unexpected events. The team also conducted tests for
compatibility with the Compact Coronagraph-1 (CCOR-1) instrument, which will monitor the sun's corona as part of NOAA's Space Weather Follow-On mission.
GOES-U remains on schedule for its planned April 2024 launch from Cape Canaveral Space Force Station in Florida, utilizing a Falcon Heavy launch vehicle. Following its successful
journey to geostationary orbit, it will be renamed GOES-19 and undergo a series of on-orbit instrument and systems checkouts, followed by the validation of its data products.
The GOES-R Series is hailed as the Western Hemisphere's most advanced weather and environmental monitoring system. Comprising four satellites, the program includes GOES-R (GOES-16),
GOES-S (GOES-17), GOES-T (GOES-18), and GOES-U. These satellites play a pivotal role in providing crucial data for weather forecasts, environmental hazard detection, and monitoring solar activity and space weather.
The GOES-R Series is set to operate into the 2030s. In parallel, NOAA and NASA are collaboratively working on the Geostationary Extended Observations (GeoXO) mission, ushering
in the next generation of geostationary satellites to address future environmental challenges for U.S. weather, ocean, and climate operations. This collaborative effort between NOAA and NASA continues to advance environmental monitoring and scientific research
from space.

Sentinel-1 Satellite Reveals Shifts from Morocco Earthquake
In the wake of the devastating earthquake that struck Morocco on September 8th, satellite data is proving to be a vital asset for emergency response teams. The International
Charter 'Space and Major Disasters,' which offers rapid support during major crises, quickly deployed Earth observation assets to assist rescue efforts.
Additionally, radar measurements from Europe's Copernicus Sentinel-1 satellite mission are being utilized to assess ground shifts caused by the earthquake. This information
not only aids in planning reconstruction efforts but also advances scientific research.
The powerful 6.8 magnitude earthquake hit the Atlas Mountains, about 75 kilometers from Marrakesh, Morocco in an area rarely affected by such seismic events.
Tragically, the earthquake resulted in significant loss of life, building collapses, and infrastructure damage. The impact was felt as far as the country's northern coast.
The International Federation of Red Cross and Red Crescent Societies, along with the United Nations Institute for Training and Research, invoked the International Charter Space
& Major Disasters. This initiative allows for the swift provision of satellite imagery to define the extent of the disaster, enhancing rescue operations.
Satellites play a crucial role in rapid damage assessment and disaster management. Recognizing this, the European Space Agency (ESA) and France's CNES space agency established
the International Charter Space and Major Disasters in 1999 to foster international collaboration in disaster response.
In alignment with this collaboration, the Copernicus Emergency Mapping Service was activated to share satellite data in response to the Moroccan earthquake. High-resolution
images from France's Pléiades satellites were used to create detailed damage maps, aiding rescue teams in their operations.
These maps assist in identifying safe routes and bridges, ensuring the safety of responders. Philippe Bally, ESA representative of the International Charter, emphasized the
urgency of delivering satellite data promptly to support relief efforts.
While the response to Morocco's disaster continues, scientists are using measurements from the Copernicus Sentinel-1 mission to assess ground changes using a technique called
'interferometry.' This helps to understand the earthquake's impact and potential future hazards.
The Copernicus Sentinel-1 mission's radar capabilities allow scientists to observe and analyze the precise effects of earthquakes on the land surface. This information is crucial
for post-disaster restoration efforts.
As Morocco works toward recovery, international space agencies and initiatives like the International Charter, alongside satellite missions such as Sentinel-1, are playing
a crucial role in easing the burden on emergency responders and advancing our understanding of seismic events. These efforts contribute significantly to global disaster mitigation.
