Скачать или смотреть [59th live stream] ULA's Atlas V 551 rocket - AV-111 - Amazon Leo (Project Kuiper) - LA-04 mission.

Hey guys, Daniel Suguwa here! Today, on Monday, 15 December 2025 (or Sunday, 14 December 2025), United Launch Alliance (ULA) will launch Atlas V 551 rocket from Cape Canaveral Space Force Station (CCSFS) for Amazon Leo (Project Kuiper) LA-04 - 27 satellites in total with 15,422 kg in total mass - into the circular low Earth orbit (LEO). It will be placed around 630 km (~391.47 miles) altitude, with the orbit inclination of 51.9°, to the northeast.

The constellation in total after this launch would be 180 satellites, out of operational planned of 3,236 satellites in total. As Amazon tends to keep the launch secretive outside the solid rocket booster (SRB) side booster separation, we might as such see the live coverage to cutoff. However, it would've been a surprise if we can see it in full action, till the full deployment of the satellites, that is.

Let's watch together, shall we? :D
