New Satellite Distance Records

/

Jérôme LeCuyer, F4DXV, set yet another distance record on October 15th when he worked Scott Richardson, N1AIA, on SO-50. Jérôme was located in JN14ch while Scott was in FN43rh, a distance of 5,645.3 km [3507.8 miles]. This eclipses the previous record of 5,548 km set by KE9AJ and MI0ILE in May.

Additionally, Puneit Singh, VU2TUM, claimed the initial distance record on Tevel-2 with a 3,815 km QSO with BA1PK in ON80eb. VU2TUM’s QTH was ML88ij.

RFI from above is Anything but Heavenly Interference

Starlink satellites are emitting RFI that is causing issues for radio astronomers, even in so-called "radio quiet zones," such as the outback of Western Australia.

That is the finding of a research team that published their findings recently in the journal, Astronomy and Astrophysics Letters. Steven Tingay of Curtin University writes on the Cosmos magazine website that, using radio telescopes, the researchers detected signals at a number of licensed radio frequencies but their greatest concern was over intended and unintended emissions from elsewhere. They traced those to Starlink satellites. The scientists' tests were conducted at the site where an SKA-Low facility is to be built in Western Australia.

Satellite Returns via Guided Re-Entry

A satellite completing its five-year mission returned to Earth using a method designed to minimise stray space debris.

A British-built weather satellite achieved an unprecedented re-entry to Earth on Friday 28th July, guided by the European Space Agency.

The spacecraft, known as Aeolus, had outlived its usefulness in gathering data and monitoring weather after a five-year mission. It returned to Earth in an assisted crash into the Atlantic Ocean. The satellite, named after the Greek god of the winds, had served weather centres across Europe.
