bert hubert 🇺🇦🇪🇺🇺🇦In 15 minutes Europe will hopefully launch its next climate satellite. The launch can however only be watched via YouTube since we apparently can’t do that ourselves and have to put our government info next to the antivax promo. https://www.esa.int/ESA_Multimedia/ESA_Web_TV
MSG APOLOGIST@bert_hubert Not yet! We'll get there... one step at a time, hopefully
codoLive streams are not rocket science. #peertube can do it.

Angela Scholder@bert_hubert Even Vimeo already would be a better option.
Wilfried Klaebe@AngelaScholder I recently learned one needs an account there now...
Harry Wood@bert_hubert Ooh! In 4 mins. It's on youtube, but nice to have commentary without an American accent!
Derick Rethans@harry_wood @bert_hubert These Vegas leap off the launchpad, don't they?
@derickr @harry_wood especially when they don’t explode!
Dr. Eric J. Fielding, PhD@bert_hubert They now say that the launch was successful, with the Biomass satellite talking to the ground stations. https://www.esa.int/Applications/Observing_the_Earth/FutureEO/Biomass/Biomass_launched_to_count_forest_carbon
Biomass launched to count forest carbon
ESA’s groundbreaking Biomass satellite, designed to provide unprecedented insights into the world’s forests and their crucial role in Earth’s carbon cycle, has been launched. The satellite lifted off aboard a Vega-C rocket from Europe’s Spaceport in Kourou, French Guiana, on 29 April at 11:15 CEST (06:15 local time).
@EricFielding the next exciting thing is unfurling the scary antenna...https://www.bbc.co.uk/newsround/articles/c0jzy3g0zx2o
@bert_hubert They have to deploy the solar cells and unfold the boom first, before unfurling the reflector. I don't know what the plan is for Biomass deployment sequence. For NISAR, the whole sequence is planned to take 9 days after launch. NISAR has a 12-meter diameter reflector and a more complicated boom structure. I see the Biomass reflector is also about 12 meters across, but it seems like a simpler design. Longer wavelength means the tolerances are larger.
Shephallmassive@bert_hubert @EricFielding apparently its P Band which is a first apparently - there are different spectrums that are used to identify leaves, tree shapes branches and tree trunks. Going to start deployment Friday (tomorrow is a bank holiday here) I think the deployment will take some days to do this. #Biomass
@Shephallmassive @bert_hubert Yes, the Biomass mission is the first P-band (70 cm wavelength) radar to be launched into space. It will be able to see deep into the dense forests. One disadvantage is that the frequency allocations mean that it cannot operate over North America or Europe and another is the coarse resolution. #biomass
