The European VLBI Network (EVN) is pleased to announce the second edition of the series of online seminars “The sharpest view of the radio Universe: VLBI – Connecting Astronomers Worldwide”. Five seminars will cover different science topics illustrating how Very Long Baseline Interferometry can improve our understanding of many astronomical phenomena and how this technique is useful for the whole astronomical community. The new seminars will start on 29 November 2021 and will be organised around every six weeks, leading up to the organisation of the 2022 EVN Symposium on 11-15 July 2022.
Following a successful first edition in 2020-2021, the seminars will comprise 35-40 minute talks, followed by a Q&A and discussion session. The seminars can be followed live via Zoom as well as through the JIVE/EVN YouTube Channel.
The first seminar will take place on Monday 29 November 2021, 16:00 CET (15:00 UTC). Giuseppe Cimò (Joint Institute for VLBI ERIC) will talk about “Observing Interplanetary spacecraft with radio telescopes: connecting astronomers and space scientists”. The seminar can be followed live on the following link.
Observations of human-made satellites using arrays of radio telescopes can provide the ultra-precise determination of their speed and their position on the celestial sphere. The Planetary Radio Interferometry and Doppler Experiment (PRIDE) is a technique that connects ground-based radio astronomy and space science to deliver the sharpest view of spacecraft in our solar system. PRIDE's precise determination of the lateral position of spacecraft can be used for a variety of scientific applications, including improvement of ephemerides, ultra-precise celestial mechanics of planetary systems, gravimetry, spacecraft orbit determination, and fundamental physics. Furthermore, observations of the radio signal transmitted by a spacecraft are an important source of information on interplanetary plasma and solar wind. In this talk, I will present novel results of observing ESA and NASA spacecraft with ground-based radio telescopes and demonstrate the capabilities of such a technique.
