ARRL Comments in Orbital Debris Mitigation Proceeding
10/13/2020
In comments to the FCC, ARRL targeted two specific areas of concern
regarding a Further Notice of Proposed Rulemaking (FNPRM) in IB Docket
18-313 - mitigation of orbital debris in the new space age. In an
earlier phase of the proceeding, ARRL filed comments and met with FCC
staff to discuss the proposed rules. In comments filed on October 9,
ARRL focused on the areas of indemnification and maneuverability/propul-
sion. Indemnification places the liability for any possible damage from
a satellite on an individual or entity. ARRL reiterated its assertion
that, as a practical matter, an indemnification requirement "would
seriously impair the ability of amateur and university experimenters to
launch and operate satellites under US auspices" due to the potential
liability and high insurance cost.

PREDICT-2.2.7 for Linux, Unix, Android, and Raspberry Pi Platforms
John Maglicane, KD2BD, has announced the release of PREDICT version
2.2.7, an Open Source satellite tracking / orbital prediction applic-
ation for Linux and Unix computing environments, including PCs, laptops,
and Raspberry PIs.
New in this release is a version of PREDICT that operates on Android
platforms under a Termux environment. Now you can carry your smartphone
in your shirt pocket while voice announcements made by PREDICT's
"vocalizer" tell you where to locate the ISS, Hubble, or other visible
satellites in the night sky! There's even an alarm to alert the observer
when the spacecraft enters into eclipse or into sunlight.
Android screenshots are available here:
https://www.qsl.net/kd2bd/SingleTrack-Android.jpg

The Linux/Unix version of PREDICT-2.2.7 is available here:
https://www.qsl.net/kd2bd/predict-2.2.7.tar.gz
And the Android/Termux release is available here:
https://www.qsl.net/kd2bd/predict-2.2.7-termux.tar.gz
Both versions are source code releases. An included "configure" script
will configure and compile PREDICT and its associated utilities for your
specific platform while you wait.
Termux is an Android terminal emulator and Linux environment application
that is available at no cost through Google Play. Further details are
available at:

+ OSIRIS-REx, which launched in 2016 and has been orbiting the asteroid
Bennu in microgravity since 2018, is going to try its first Touch And
Go (TAG) maneuver next week. This maneuver involves autonomously des-
cending toward the asteroid with the craft's sample arm extended,
briefly making contact, using nitrogen gas to blow loose material in-
to a sample collection head, and returning to orbit. The pristine
sample should arrive back on Earth in September 2023. Visualization

+ Blue Origin's reusable suborbital New Shepard flew on October 13 for
the first time since December 2019, completing its 13th flight, and
seventh reuse for this booster. The mission successfully carried sev-
eral NASA experiments, including a "microgravity LilyPond"--a hydro-
ponic chamber for growing edible aquatic plants in space--and a sys-
tem for precise planetary landing that uses both terrain relative
navigation (for high altitude use, soon to be used for landing by
Mars 2020) and LiDAR (for final propulsive landing), with a planned
application to upcoming lunar landing missions.

+ Soyuz crew docks with International Space Station: In a mission marking
the end of an era, NASA astronaut and former virus hunter Kate Rubins,
using NASA's last currently contracted seat on a Russian Soyuz
spacecraft, rocketed into orbit Wednesday with two cosmonaut crewmates
on a record-setting flight to the International Space Station.
Celebrating her 42nd birthday, Rubins' launch came just two weeks
before 20th anniversary of the arrival of the station's first crew on
Nov. 2, 2000. Since then, the lab complex has been continuously staffed
by rotating crews, or expeditions, of American, Russian, Japanese,
European and Canadian fliers along with a handful of space tourists.

+ Oxygen supply fails on Russian segment of ISS, crew not in danger
(Oct 15, 2020) The oxygen supply system has failed in a module on the
Russian segment of the International Space Station (ISS) but the crew
is in no danger, Russian space agency Roscosmos said Thursday.
The oxygen supply system on the Zvezda module on the orbital lab failed
late on Wednesday but a second system on the American segment is
operating normally, a Roscosmos spokesperson told AFP.
"Nothing threatens the security of the crew and the ISS," said the
spokesperson, adding this repair work to fix the issue would be carried
out on Thursday.
The issue arose after three new crew -- two Russian cosmonauts and an
American astronaut -- reached the ISS on Wednesday to bring the number
of current crew on board to six. Additional information

Tips for the New Satellite Operator [Tentative Add-on FOR CONSIDERATION]
This is the first of a what I hope to be a monthly New Satellite Opera-
tors Corner. I will offer AMSAT New Operator tips and links to AMSAT
resources for new operators and posts from various interest groups where
useful info is published. This weeks tip comes from Rick, WA6NDR via
TH-D74A@groups.io. I hope you find this as useful as I have.
Jack, KD4IZ, Editor, AMSAT News Service.
Tip of the month: TH-D74A ISS APRS settings
From: Rick - WA6NDR
"I was able to make an ISS APRS contact today with just the TH-D74A and
an Arrow antenna (details at the end). I started with a video from Don
W6GPS and documented what I ended up doing including minor changes.
Change the call sign and email address to yours. "Personal preference"
settings are optional. The reasoning behind most of the settings is
given in Don's video. I am using TH-D74A firmware v1.10 (with v1.11
released 8/26/2020 but not seeming worth the installation time)."
