A lithium mine ramps up as Canada grants $2,8 bil to a Swedish battery company to set up. Historic? Governments have a long history of proping up the car industry. And guess what: today's cars stand still and parked 95% of the time! cbc.ca/news/climate/canada-q…

Canada is pouring billions of dollars into the electric vehicle industry. Will it pay off? | CBC...

This week, Quebec and Ottawa committed $2.7 billion toward an electric vehicle battery factory near Montreal. Such projects have faced questions, given the amount of public money involved.

If Vega-C is not going to be ready in early 2024, ESA needs to contract SpaceX to launch the Sentinel-1C satellite (if not risk waiting until end of 2024). Data from Sentinel-1 is far too important for socioeconomic, strategic and environmental monitoring around the world!

I preface this announcement with the disclaimer that while my source does work for @Avio_Group, they are not directly involved with the independent inquiry or with the development of the Zefiro 40 (Z40) motor. According to my source, they have heard that the Z40 nozzle has been identified as the cause of the failure and will need to be redesigned before the stage can reenter operational flight. If this is the case, a late 2024 return to flight is probably the best-case scenario. While this is a huge blow for Vega C, it may very well be a fantastic opportunity for some European launch startups to swoop in and fill the vacancy.
