* HamSCI has announced Personal Space Weather Station sessions via zoom. The Personal Space Weather Station (PSWS) network is a distributed series of receivers designed to measure the space environment. These stations are built by professionals, citizen scientists, and ham radio operators. HamSCI and its partners are constantly at work on expanding the network, improving the PSWS data collection hardware and software, growing the network infrastructure for data storage and retrieval, as well as meeting HamSCI's ultimate goal, analysis of the collected data. HamSCI has announced a recurring series of Zoom based sessions to help those interested in the project. Sessions occur each Thursday at 10:00 AM Eastern. More information is available on the HamSCI website https://hamsci.org/get-involved. [ANS thanks hamweekly.com for the above information.]
* The High-frequency Active Auroral Research Program (HAARP) will be conducting a research campaign January 27-31 UTC, with operating times specified in the table below. Operating frequencies will vary, but all HAARP transmissions will be between 2.75 MHz and 10 MHz. Actual transmit days and times are highly variable based on real-time ionospheric and/or geomagnetic conditions. All information is subject to change. Research topics for this campaign include VLF generation and ducting, studies on STEVE airglow, and space debris detection. This campaign will also support the GIRAFF rocket launch from Poker Flat Research Range, which is investigating the mechanisms that cause flickering and pulsing within the aurora. Note that a number of experiments will be conducted based on the critical frequency (f0F2) determined by the Gakona ionosonde. The included transmission notice supplement contains information on the frequencies HAARP is authorized to transmit. HAARP transmissions will only occur on our authorized frequencies.

* Electric propulsion is being increasingly used on space missions and could ultimately replace thrusters using chemical rockets. Spacecraft powered by electric propulsion could soon be better protected against their own exhaust, thanks to new supercomputer simulations. Electric propulsion is a more efficient alternative to traditional chemical rockets, and there are even plans to use electric propulsion on NASA's Lunar Gateway space station. The idea behind electric propulsion is that an electric current ionizes (i.e. removes an electron from) atoms of a neutral gas, such as xenon or krypton, stored on board a spacecraft. The ionization process produces a cloud of ions and electrons. Then a principle called the Hall effect generates an electric field that accelerates the ions and electrons and channels them into a characteristically blue plume that emerges from the spacecraft at over 37,000 mph (60,000 kph). Hence an electric propulsion system is also referred to as an ion engine. More information at https://tinyurl.com/ANS-026-ION. [ANS thanks space.com for the above information.]
