Welcome, pricey folk of the subreddit! I am u/hitura-nobad, bringing you stay updates on the StarlinkV1-L4 mission.
Starlink-4 will begin the fourth batch of operational Starlink satellites into orbit aboard a Falcon 9 rocket. This would perchance seemingly also be the fifth Starlink mission overall. This begin is no longer expected to be a lot like the old Starlink begin in leisurely January, which noticed 60 Starlink v1.0 satellites dropped at a single airplane at a 290 km altitude. This time SpaceX is focusing on a 386×212 km Orbit . In the following weeks the satellites will bag turns shifting to the operational 550 km altitude in three groups of 20, making spend of precession charges to separate themselves into three planes. Attributable to the excessive mass of several dozen satellites, the booster will land on a drone ship at a identical downrange distance to a GTO begin.
It’s doubtless you’ll perchance evaluation this launchs flight profile to the closing here.
