SpaceX throwing away a Booster – Eutelsat 10B [NEW Live: 23.11.2022, UTC 02:57]
First attempt scrubbed:
Standing down from tonight’s launch of the Eutelsat 10B mission to allow for additional pre-flight checkouts; now targeting tomorrow, November 22 at 9:57 p.m. ET for liftoff. Weather is currently 20% favorable

SpaceX expending a booster has become a rare thing. This mission needs all the squeeze that is to be had out of a Falcon 9 rocket booster. No grid fins, no landing legs and no extra fuel to land the stage. All in the name if saving weight and pushing as much mass into orbit as possible. The target orbit is a geostationary transfer orbit. There is so much squeezing of the plant that SpaceX can do. The booster stage is also on its 11th mission.
(SpaceX will recover fairings 😉 )
Weather is 30% go according to the 45th Weather Squadron.
Why is it necessary to waste a young Falcon booster stage for a mere 4’500 kg payload? Orbial mechanics is a strange topic. Here is Scott Manley with a handy video:
