SpaceX Dragon Capsule Ferries Four Radio Amateurs to the ISS
A SpaceX Dragon capsule carrying four radio amateurs autonomously docked on November 17 at 0401 UTC with the International Space Station (ISS). A SpaceX Falcon 9 launcher carrying the precious payload went into space on Sunday, November 15, from NASA's Kennedy Space Center. They comprise the ISS Expedition 64/65 crew.
"Well, the ISS is loaded with hams now," Amateur Radio on the Inter- national Space Station (ARISS) US Delegate for ARRL Rosalie White, K1STO, said on Tuesday. "These four arrived very early this morning Eastern Time: NASA astronauts Victor Glover, KI5BKC; Mike Hopkins, KF5LJG, and Shannon Walker, KD5DXB, as well as Japan Aerospace Explora- tion Agency (JAXA) astronaut Soichi Noguchi, KD5TVP." This marks Glover's first time in space. The others all are ISS veterans.
Earlier this year, NASA ISS Ham Project Coordinator Kenneth Ransom, N5VHO, held amateur radio licensing study sessions for Glover, who passed the Technician-class exam on August 20.
The four will remain on station until next spring. They joined Expedi- tion 64 Commander Sergey Ryzhikov and Flight Engineer Sergey Kud- Sverchkov of the Russian space agency Roscosmos, on the ISS.
White said all but Noguchi likely will take part in ARISS contacts with schools. White said the first school contact is tentatively scheduled for December 4 with Tecumseh High School in Oklahoma, home of the Tecumseh High School Amateur Radio Club, K5THS. She said the students have earned their ham licenses, and the club has built an antenna and is learning about satellites and circuits. Members of the South Cana- dian Amateur Radio Society of Norman, Oklahoma, are providing support and mentoring assistance.
The Sunday launch from Kennedy Space Center marked only the second crewed-flight for the SpaceX Crew Dragon, which became the first commer- cial vehicle to put humans into orbit when astronauts Doug Hurley and Bob Behnken, KE5GGX, launched in May, and NASA gave SpaceX the go for future such launches.
"The return of human spaceflight to the United States with one of the safest, most advanced systems ever built is a turning point for Amer- ica's future space exploration," SpaceX claimed, "and it lays the groundwork for missions to the moon, Mars, and beyond."

New Launch Date for EASAT-2 and Hades Satellites
AMSAT-EA President Felix Paez, EA4GQS, has announced the scheduled launch date for AMSAT-EA satellites EASAT-2 and HADES. Flying with SpaceX, the two nanosats are scheduled for launch on January 14, 2021. They have been already delivered and integrated on the Alba Orbital deployer.
The satellites have been configured to act as FM voice and FSK data repeaters and not as linear transponders as was the initial plan. In any case, they are believed to be the smallest satellites ever given such a function, as their size is only 7.5 x 5 x 5 cm.
Hades also flies a SSTV camera that will take and send pictures each 15 minutes. The camera module design is based on the one used in the PSAT2 satellite, adapted for AMSAT-EA by the Brno University of Technology.
Hades – FM voice repeater, callsign AM6SAT uplink 145.925 MHz (no tone), downlink 436.888 MHz EASAT-2 – FM voice repeater, callsign AM5SAT uplink 145.875 MHz (no tone), downlink 436.666 MHz Both satellites have also digitized FM voice beacons and FSK data re- peaters.
These are the first satellites built by AMSAT-EA, with the project leaders being all Spanish radio amateurs and almost all the engineering made by radio amateurs with help of students of two universities. While AMSAT-EA doesn't have the flight heritage of other AMSAT organizations, this is an important step for the organization as it moves to improve skills in order to build better satellites for the radio amateur satel- lite service in the future.

Arecibo Observatory Faces Demolition After Cable Failures
After withstanding hurricanes and earthquakes, playing central roles in movies like “GoldenEye” and “Contact,” Puerto Rico’s famed Arecibo Observatory, once the largest radio telescope in the world, will be demolished because of cable failures that left its huge detector plat- form too unstable to attempt repairs.
“After reviewing the engineering assessment, we have found no path for- ward that would allow us to do so safely,” said Sean Jones, assistant director for the Mathematical and Physical Sciences Directorate at the National Science Foundation.
“We know that a delay in decision making leaves the entire facility at risk of an uncontrolled collapse, unnecessarily jeopardizing people and also the additional facilities.”
Operated by the NSF through the University of Central Florida, the iconic observatory is made up of a fixed 1,000-foot-wide dish antenna built into a bowl-like depression that reflects radio waves or radar beams to a 900-ton instrument platform suspended 450 feet above by cables stretching from three support towers.
For 57 years, the observatory has played a leading role observing deep space targets, bodies in the solar system and, using powerful lasers, the composition and behavior of Earth’s upper atmosphere.
But the beginning of the end came on Aug. 10 when an auxiliary cable installed in the 1990s pulled free of its socket on one support tower and crashed onto the dish below, ripping a 100-foot-long gash.
Engineers were developing repair plans when one of the main 3-inch-wide cables attached to the same tower unexpectedly snapped on Nov. 6, causing the instrument platform to tilt and putting additional stress on the remaining cables.
An analysis showed the cable failed in calm weather at about 60 percent of of its minimum breaking strength. Inspections of other cables showed fresh wire breaks and slippage in several auxiliary cable sockets that were added to the structure in the 1990s.
An engineering firm hired by the University of Central Florida to assess the structure concluded it would be unsafe to proceed with repairs. Even stress tests to determine the strength of the remaining cables could trigger a catastrophic collapse.
Instead, engineers recommended a controlled demolition, bringing down the suspended instrument platform in a way that will prevent damage to other structures at the periphery of the dish by making sure the towers themselves don’t collapse and by ensuring no cables whip into those structures.
“The telescope is at serious risk of an unexpected, uncontrolled col- lapse,” said Ralph Gaume, director of NSF’s Division of Astronomical Sciences. “According to engineering assessment, even attempted stabil- ization, or testing the table could result in accelerating the catas- trophic failure.
“Engineers cannot tell us the safety margin of the structure, but they have advised NSF that the structure will collapse in the near future on its own.”
Plans for bringing down the instrument platform have not yet been fin- alized and it’s not yet known whether explosives will be used in a controlled demolition or whether it might be possible to somehow lower the platform to the dish below.
However it plays out, the 1,000-foot-wide telescope will essentially be destroyed. While the laser facility and visitor’s center will hope- fully be preserved, the radio telescope itself will be no more.

DX Portable Operation Planned From Thailand Grid NK99
The Thailand’s Amateur Radio Satellite group (AMSAT-HS) has requested permission to establish a temporary station (DX portable) with the northern office of the NBTC, Thailand’s regulator, in Chiang Mai and Mae Hong Son (grid NK99) provinces in the north of Thailand during the period from November 26-28, 2020 to communicate via All LEO and MEO amateur radio satellites (including QO-100 NB) that pass over Thailand using the callsign HS0AJ/P of the Radio Amateur Society of Thailand under the Royal Patronage of His Majesty the King.
Hence we would like to notify all radio amateurs who would interested in contacting stations in Thailand on its northern border of this ac- tivity. Even if the angle is as low as 0 degrees please try to contact us. We hope to meet you on all satellites frequency then.

Human Error Blamed For Vega Launch Failure
Arianespace executives said Nov. 17 that the failure of a Vega launch the previous day was caused when the rocket’s upper stage tumbled out of control due to incorrectly installed cables in a control system.
In a call with reporters, Roland Lagier, chief technical officer of Arianespace, said the first three stages of the Vega rocket performed normally after liftoff from Kourou, French Guiana, at 8:52 p.m. Eastern Nov. 16. The Avum upper stage then separated and ignited its engine.
However, “straightaway after ignition” of the upper stage, he said, the vehicle started to tumble out of control. “This loss of control was permanent, inducing significant tumbling behavior, and then the trajec- tory started to deviate rapidly from the nominal one, leading to the loss of the mission.”
Analysis of the telemetry from the mission, along with data from the production of the vehicle, led them to conclude that cables to two thrust vector control actuators were inverted. Commands intended to go to one actuator went instead to the other, triggering the loss of con- trol.
“This was clearly a production and quality issue, a series of human errors, and not a design one,” Lagier said.
The failure caused the loss of two spacecraft, the SEOSAT-Ingenio Earth observation satellite for Spain and the TARANIS satellite for France to study electromagnetic phenomena in the upper atmosphere. [No amateur satellites were involved -- Ed.]

Satellite Shorts From All Over
+ Happy 7th birthday to AO-73, FUNcube-1, which was launched on Novem- ber 21,2013. Congratulations to AMSAT-UK on the ongoing success of this project. (ANS thanks AMSAT-UK for the above information)
+ South Dublin Radio Club has uploaded its latest video to the club's YouTube channel. The video was created for Science Week in collabor- ation with Dublin Maker & Science Foundation Ireland and is called "Signals from Outerspace! Make your own antenna to get images from Weather Satellites." It is designed as a beginner's radio project and instructs viewers on how to construct a very simple V-dipole for 137 MHz, demonstrating how it can be utilised along with a basic SDR and computer in order to decode images from NOAA Weather satellites. It's available at https://www.youtube.com/watch?v=8doUGhNKzdY (ANS thanks Southgate ARC for the above information)
+ Sean Kutzko, KX9X, is creating a series of YouTube videos for the DX Engineering channel beginning with "How and Why to Get Started in Op- erating Amateur Radio Satellites." Later episodes build on the con- cepts in the first. See the first episode at: https://www.youtube.com/watch?v=Vp7h4ikthDQ (ANS thanks Sean Kutzko, KX9X, for the above information)
+ APSS-1, a 1U CubeSat mission with deployable solar panels, built by The University of Auckland (New Zealand), Faculty of Engineering, was launched on November 20. The satellite is intended for monitoring of ionosphere activity and transmission of processed data to ground stations using a 9k6 GMSK AX 25 downlink on 435.100 MHz. APSS-1 will start transmitting 45 minutes after deployment, and will only beacon every 5 minutes initially. (ANS thanks Mark Jessop, VK5QI, for the above information)
+ The Rocket Lab flight that took APSS-1 to orbit (see immediately above) was notable because Rocket Lab says the first stage of its Electron launcher splashed down under parachute in the Pacific Ocean off New Zealand after firing into space with 30 small satellites, be- coming only the second private company to return an orbital-class booster to Earth intact. The privately-developed Electron rocket has flown 16 times, including Thursday’s mission, but this was the first time an Electron rocket flew with parachutes to attempt a full series of descent maneuvers. (ANS thanks SpaceflightNow for the above information)
+ NASA "Scan" on Facebook has published a note about ARISS and its 20 years.
