AMSAT has now granted OSCAR status to 100 Amateur Radio satellites. The latest, Es’hail-2/P4A — now Qatar-OSCAR 100 (QO-100) —launched from Cape Canaveral, Florida, in November. It carries the first geosynchronous Amateur Radio payload. Es’hail-2/P4A was developed jointly by the Qatar Amateur Radio Society (QARS) and Es’hailSat (the Qatar Satellite Company), with AMSAT-DL as the […]

via the ARRL: Earth’s Magnetic North Pole Shifts toward Siberia

National Centers for Environmental Information (NCEI) scientists have updated the world magnetic model (WMM) mid-cycle, as Earth’s northern magnetic pole has begun shifting quickly away from the Canadian Arctic and toward Siberia, an NCEI report said this week. The new WMM more accurately represents the change of the magnetic field since 2015. The alteration could have an […]

via HACKADAY: The 1859 Carrington Event

Like many Victorian gentlemen of means, Richard Carrington did not need to sully himself with labor; instead, he turned his energies to the study of natural philosophy. It was the field of astronomy to which Carrington would apply himself, but unlike other gentlemen of similar inclination, he began his studies not as the sun set, […]

via the RSGB: Slow-scan TV experiment on ISS

The Inter-MAI amateur radio slow scan television experiment on the International Space Station is scheduled to be activated between Wednesday, 30 January and Friday, 1 February. It appears that the experiment will only be active during a couple of orbits that overfly Moscow, rather than a continuous operation. Expected periods of activation appear to be […]

via the ARRL: Reports of Knacksat CubeSat Reception Requested

The Knacksat 1U CubeSat launched on December 3 by a SpaceX vehicle may be in safe mode. The Knacksat project team at King Mongkut’s University of Technology-North Bangkok, Thailand, has speculated that launch delays may have led to battery depletion, preventing normal antenna deployment. Safe mode will let the spacecraft recharge its battery and receive commands from […]

via the ARRL: New D-Star ONE Nanosatellites Launched; Es’hail Testing Under Way

A December 27 Soyuz launch deployed the two German Orbital Systems D-Star ONE satellites D-Star ONE – Sparrow and D-Star ONE – iSat. Beacons have been successfully received from both satellites, which carry a D-Star repeater with an uplink at 437.325 MHz and downlink at 435.525 MHz. The D-Star ONE – Phoenix 3U CubeSat, launched last February, was […]
