The RSGB have posted an update on activities at the 2019 World Radiocommunication Conference during Tuesday, November 5.
A somewhat difficult start to the day’s proceedings began with another AI-10 Proposal being introduced for WRC-23 – protecting RNSS (Galileo etc) from secondary amateur usage in the 23cm band.
Future mobile/IMT was also being discussed in the 3-18 GHz range (including our 10 GHz band). Another item may even affect 241 – 700GHz. It will be a while before the WRC-23 agenda down-selection gets agreed at the conference. A busy day then continued as a raft of topics was attended, with few signs of positive progress.

Astronauts Unload U.S. Resupply Ship to Continue Advanced Space Research
The U.S. Cygnus space freighter is pictured as the Canadarm2 robotic arm reaches out to grapple the 12th resupply ship from Northrop Grumman.
A new U.S. resupply ship is open for business and the Expedition 61 crew has begun unloading over four tons of new science experiments and station hardware. Two astronauts are also studying advanced repair techniques for a cosmic particle detector attached the International Space Station.
The astronauts opened the hatches on Northrop Grumman’s Cygnus resupply ship after its arrival on Monday and immediately started unpacking and activating critical science payloads. Mice delivered aboard Cygnus are now living in station habitats to help scientists understand how microgravity impacts metabolic rates. The rodent study may provide therapeutic insights into Earth-bound ailments such as diabetes and liver disease.
Cygnus science freezers containing valuable research samples for observation are now operating inside station research racks. The crew will utilize the samples to study a variety of microgravity phenomena to benefit Earthlings and astronauts. New experiments will research how microbes affect space hardware and astronauts and explore how weightlessness affects muscle gene expression.
Cygnus also delivered hardware to enable the complex repair job required to upgrade the Alpha Magnetic Spectrometer’s (AMS) thermal control system. Astronauts Luca Parmitano and Andrew Morgan are preparing for several spacewalks to cut and reconnect fluid lines to ensure the AMS continues its search for dark matter and antimatter for years to come.
Cosmonauts Alexander Skvortsov and Oleg Skripochka logged their meals and medicine intake today to help researchers understand how space impacts bone tissue. The duo worked on a variety of Russian maintenance tasks then reviewed Cygnus emergency procedures with the rest of their Expedition 61 crewmates.

Orson John helps prepare Ice, Cloud and land Elevation Satellite-2 (ICESat-2) for encapsulation in the United Launch Alliance Delta II payload fairing on Sept. 4, 2018, at Space Launch Complex 2 at Vandenberg Air Force Base in California.
Among the presenters were:
• Stuart Robinson GW7HPW, $50SAT Team
• Julian Fernandez EA4HCD, Fossasat-1
• Zac Manchester KD2BHC, Chipsats
• Constantin Constantinides MM6XOM, Unicorn-2

Cygnus Resupply Ship Attached to Unity for Cargo Operations
Nov. 4, 2019: International Space Station Configuration. Four spaceships are attached to the space station including the Northrop Grumman Cygnus resupply ship and Russia’s Progress 73 resupply ship and Soyuz MS-13 and MS-15 crew ships.
After its capture this morning at 4:10 a.m. EST, the Northrop Grumman Cygnus spacecraft was bolted into place on the International Space Station’s Earth-facing port of the Unity module at 6:21 a.m. At the time of installation, Cygnus was flying over the south Pacific.
This mission, designated NG CRS-12, will be in orbit at the same time as its predecessor, the NG CRS-11 Cygnus spacecraft, which launched in April on an extended duration flight. The NG CRS-12 Cygnus spacecraft will remain at the space station until January before it disposes of several thousand pounds of trash through its fiery reentry into Earth’s atmosphere. The ability to fly two vehicles at once further demonstrates the robustness of Cygnus to support the goals of NASA’s ambitious missions.
The spacecraft’s arrival brings close to 8,200 pounds of research and supplies to space station. Here are some of the scientific investigations:
More Probing of Mysteries of the Universe
This mission carries components needed to prolong the operational life of Alpha Magnetic Spectrometer-02 (AMS-02). In a series of spacewalks planned in the coming weeks, astronauts will cut and reconnect fluid lines on the instrument, a feat not done before in space, which could prove valuable for future missions at NASA’s upcoming lunar Gateway for the Artemis program or missions to Mars.
Testing Personal Protective Equipment for Astronauts
The AstroRad Vest tests a special garment designed to protect astronauts from radiation caused by unpredictable solar particle events. Astronauts will provide input on the garment as they wear it while performing daily tasks. Use of the vest could protect crew members on missions to the Moon and Mars.
Food Fresh from the Oven
The Zero-G Oven examines heat transfer properties and the process of baking food in microgravity. It uses an oven designed specifically for use aboard the space station, and may have application on future long-duration missions by offering a way to increase variety in flavor and nutrition of food for crew members.
3D Printing with Recycled Materials
The Made in Space Recycler will test systems needed to reprocess plastic into 3D printing filament that can then be transferred for use to the Made in Space Manufacturing Device, a 3D printer that has operated on the orbiting laboratory since 2016. This has implications for space conservation and deep space missions.
