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.
More information and photos of these and other upcoming AMSAT-EA pro-
jects is available at https://bit.ly/3lNjTJq

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. Look for their post dated on November 16 at:
https://www.facebook.com/NASASCaN and add a comment to let them know
that we amateur radio ops are here and that it was great they had
dedicated a post to ARISS and to all hams!
(ANS thanks Fernando Casanova, EC1AME, for the above information)
+ Talks from the DEF CON event are available on YouTube, they include
a number of amateur radio talks from the conference's Ham Radio Vil*
lage. Among the amateur radio talks is "Talking to Satellites" by
Eric Escobar, KJ6OHH. See the playlist at: https://bit.ly/3fpuwzO
