       📆 February 26, 2023 #Argon-fueled #HallEffectThruster for #Starlink V2 #satellites 🛰️ : Relative to #krypton, the argon required to fuel Starlink V2 satellites will be practically free. 99.999%-pure argon can be purchased in low volumes for just $5 to $17 per kilogram. Fueling ⛽ its next constellation of almost 30,000 V2 satellites could cost #SpaceX less than fueling 4000 V1 satellites. https://www.teslarati.com/spacex-unveils-next-gen-starlink-v2-mini-satellites-ahead-of-monday-launch

       @spaceflight what’s the trade off in deltav? SpaceX probably needs to lift more mass into LEO to get the same satellite into position/manoeuvrability.

       @hpridham why do you think it's more mass ? If the #satellites live longer, it's less mass they have to lift to #LEO
