ARISS Press Conference on Columbus Radio System
March 10, 2021 at 1900 UTC (2000 Belgian Time)

The ARISS team will conduct a 45-minute press conference for media this Wednesday March 10 at 1900 UTC (2000 Belgian Standard Time). This press conference will focus on the ARISS Radio system mounted in the Columbus module.

As a reminder, the ARISS team has been working very closely with NASA and ESA to identify potential causes of an ARISS radio anomaly first observed after the EVA (spacewalk) conducted on January 27.  No transmissions or receptions have been heard from this radio since the EVA.  During the spacewalk, cabling was installed to support the commissioning of the Bartolomeo attached payload capability mounted on Columbus.  Part of this effort rerouted the ARISS antenna cable through one of the Bartolomeo cables.

Radiosondes KMI-IRM
Submitted by: ON7YD
We received following question, from KMI-IRM:

"As most of you know, the Royal Meteorlogical Institute of Belgium (KMI-IRM) is launching 3 times a week radiosondes coupled to ozonesondes from its site at Uccle. With these measurements, we monitor the ozone layer above Belgium and the meteorological data are used to constrain the numerical weather models that provide a weather forecast."
