New FCC Ruling Presents a New Set of Challenges
Until now, all spacecraft had to either deorbit or move to a disposal orbit no later than 25 years after the end of their mission. With the Federal Communication Commission’s (FCC) new ruling, they must come down sooner.
The FCC’s new orbital debris mitigation ruling, FCC 22-74, requires non-geostationary satellite operators that terminate their satellite operations or pass through the Low Earth Orbit region below 2,000-kilometer (1246 miles) altitude, complete disposal as soon as practicable following the end of mission, and no later than five years after the end of its primary mission. The goal is to minimize the risk of collisions that would create debris.
*Space-X satellites orbit 340 miles up. The ISS orbit is about 240 miles up. Based upon maneuvering fuel, Space-X is predicting a 7 year life for their communication satellites which may be commanded to change orbit 8x/day.
The FCC defines “end of mission” to be “the time at which the individual spacecraft is no longer capable of conducting collision avoidance maneuvers,” and, for spacecraft without collision avoidance capabilities, end of mission is defined as the point at which the individual spacecraft has completed its primary mission.
Furthermore, the FCC requires a demonstration that the probability of success of the chosen disposal method will be 90 percent or greater. This new rule-making will have a significant effect on AMSAT’s future satellite operations.
OMOTENASHI Struggling to Carry Amateur Radio to the Moon Amstat Bulletin ANS-324 11/20/22
OMOTENASHI, a project of the JAXA Ham Radio Club, (Japan Aerospace Exploration Agency) was a secondary payload aboard NASA’s Artemis 1 mission, launched along with the Orion space capsule from Cape Canaveral on November 16. It was planned to land on the surface of the moon, and to transmit with a 1 watt beacon in the amateur 70cm band.
Of the ten CubeSats flown as secondary payloads with the Orion space capsule, seven are operation, two have not been heard from.
OMOTENASHI, a Japanese word for hospitality, is derived from Outstanding MOon exploration TEchnologies demonstrated by NAno Semi-Hard Impactor.
Controllers have reported OMOTENASHI is tumbling, making it difficult for the spacecraft to charge its batteries and communicate with the ground. Controllers are continuing recovery attempts, but it’s Moon landing mission window has closed permanently.
OMOTENASHI is a 6U-CubeSat with external dimensions of 239 x 366 x 113mm and an approximate mass of 14 kg. (9.5 x 14 x 4.5 inches and 30 lb). It’s cost was $5.6 million US and would have made Japan the 4th nation with a probe on the Moon.

U.S. High School CubeSat to be APRS Relay
TJREVERB, a 2U CubeSat built by Thomas Jefferson High School for Science & Technology, has been frequency coordinated to operate as an APRS relay on 145.825 MHz. It is scheduled for launch on a SpaceX Falcon 9 rocket and Dragon spacecraft set to deliver additional science, crew supplies, and hardware to the International Space Station next week. The satellite will be released from ISS at a later time.
The first U.S. high school to send a CubeSat to space back in 2013, Thomas Jefferson High School for Science and Technology’s Research and Education Vehicle for Evaluating Radio Broadcasts satellite aims to study the use of iridium as a primary radio communication method. Additionally, the satellite will demonstrate using a passive magnet onboard and the Earth’s magnetic field for stabilization rather than using an attitude determination and control system for pointing accuracy and stabilization for iridium. What makes this satellite even more notable is that it was a system’s engineering project. The students selected space-grade parts, wired the electronics for the satellite, wrote the drivers to control the different systems, and coded the flight software.
“What’s special about TJREVERB isn’t necessarily the mission, it’s what we did. These kids literally built a satellite the way the industry would build a satellite; we selected parts from vendors and got those parts to work together,” said Kristen Kucko, robotics lab director and the school’s space faculty advisor. “This is an engineering feat.”
The Iridium Satellite Constellation Network
provides L band (1-2 GHz) voice and data information coverage to satellite phones, pagers and integrated transceivers over the entire surface of Earth. Iridium Communications owns and operates the constellation, additionally selling equipment and access to its services.
The constellation consists of 66 active satellites in orbit, required for global coverage, plus additional spare satellites to serve in case of failure.
Satellites are placed in low Earth orbit at a height of approximately 781 kilometres (485 miles)
The nearly polar orbit and communication between satellites via Ka band inter-satellite (26-40GHz) links provide global service availability (including both poles, oceans and airways), regardless of the position of ground stations and gateways.
GlobalStar Satellite Network
What is the main difference between Iridium and GlobalStar?
The main difference between Iridium and Globalstar is the relaying mechanism.
While Iridium requires relaying between satellites via Ka band links, GlobalStar requires relaying between satellites and network station “brains” on earth. GlobeStar currently operates using 11.5 MHz across the United States and now LTE 5G on 2.4 GHz.
They have also begun to use the L band as consumer satellite communication grows worldwide. The FCC has authorized GlobalStar to use 65.1 GHz (so called 6G “mm” internet and cell phone)
The Globalstar project was launched in 1991 as a joint venture of Loral Corporation and Qualcomm.
Apple's new 450 million dollar investment provides critical enhancements to Globalstar's satellite network and ground stations, ensuring iPhone 14 users are able to connect to emergency SOS services when off the grid. At Globalstar, more than 300 employees support the new service.
CAPSTONE Arrives to Orbit at the Moon
The CAPSTONE mission operations team confirmed that NASA’s CAPSTONE spacecraft arrived at its orbit at the Moon Sunday evening. The CubeSat completed an initial orbit insertion maneuver, firing its thrusters to put the spacecraft into orbit, at 12:39 UTC on Nov. 13.
CAPSTONE is now in a near-rectilinear halo orbit, or NRHO. This particular NRHO is the same orbit that will be used by Gateway, the Moon-orbiting space station that will support NASA’s Artemis missions. CAPSTONE is the first spacecraft to fly an NRHO, and the first CubeSat to operate at the Moon.
In the next five days, CAPSTONE will perform two additional clean-up maneuvers to refine its orbit. After these maneuvers, the team will review data to confirm that CAPSTONE remains on track in the NRHO.
CAPSTONE – short for Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment – is a precursor to the Gateway project to establish a crewed space station in orbit around the moon. AMSAT, along with our ARISS partners, is developing an Amateur Radio package, including two-way communication capability, to be carried on-board Gateway in lunar orbit.
What Is CAPSTONE
A lunar orbiter that will test and verify the calculated orbital stability planned for the Lunar Gateway space station. Capstone is a 12-unit CubeSat the size of a microwave weighing 55 lbs that will also test a navigation system that will measure its position relative to NASA's Lunar Reconnaissance Orbiter (LRO) without relying on ground stations. It was launched on June 28th 2022, and arrived in lunar orbit on 14 November 2022. It’s scheduled to orbit for six months.
What is Lunar Gateway ?
The Lunar Gateway, or simply Gateway, is the first planned extraterrestrial space station in lunar orbit intended to serve as a solar-powered communication hub, science laboratory, and short-term habitation module for government-agency astronauts, as well as a holding area for rovers and other robots. It is a multinational collaborative project involving four of the International Space Station partner agencies: NASA, European Space Agency (ESA), Japan Aerospace Exploration Agency (JAXA), Canadian Space Agency (CSA) plus10 more. It is planned to be both the first space station beyond low Earth orbit and the first space station to orbit the Moon.
The manned Artemis 4 mission in the reusable Orion space capsule is hoped to dock with Gateway orbiting the Moon sometime in 2027-8.
What Is the Lunar Reconnaissance Orbiter ?
(LRO) is a NASA robotic spacecraft currently orbiting the Moon in an eccentric polar mapping orbit. Data collected by LRO have been described as essential for planning NASA's future human and robotic missions to the Moon. Its detailed mapping program is identifying safe landing sites, locating potential resources on the Moon, characterizing the radiation environment, and demonstrating new technologies.
Launched on June 18, 2009, in conjunction with the Lunar Crater Observation and Sensing Satellite (LCROSS), as the vanguard of NASA's Lunar Precursor Robotic Program,\

The LRO mission life was expected to last 1-2 years. 13 years later, it is still orbiting and working. LRO might well operate through 2027 depending on its fuel reserves.
Are LRO, LCROSS, CAPSTONE, Gateway, and Orion, all part of NASA’s Artemis mission?
YES. The plan of the Artemis mission is to return man to the Moon surface with Artemis 3. Artemis 4 will dock with and crew, a robotic/manned space station (GATEWAY) orbiting the Moon. This will allow regular robotic and manned excursions to the Moon surface.
