The story of Rajeev Badyal, Amazon's head of Project Kuiper who was fired by Elon Musk in 2018, makes it all the more compelling to compare the vastly different designs for Kuiper and Starlink. https://t.co/lNN5BNkFBk

This is the first time we've seen what Amazon's Kuiper satellites look like. They deployed in darkness, but their trapezoidal shape reminds me of OneWeb—clearly a far different design than Starlink.

Take a look at this @ULAlaunch clip of the first Kuiper satellites being released into low Earth orbit approximately 280 miles above the planet. Deployment takes place over a 15-minute period after launch, with satellites released three at a time from the dispenser system. https://t.co/bZ1zUy3IWs

Did all those mega-constellation launches a few days ago (five in ~24 hours) break something?

Jonathan McDowell @planet4589

Now it's three days with no public @SpaceTrackOrg orbital data for ANY satellite, and no reentry info for ANY satellite. That's not exactly a "delay"; I don't recall a complete outage this long before.

Watching live, I thought the rocket exploded at staging, but the upper stage kept going, so I relaxed, at least for a moment. It turns out my initial instinct may have been right. https://t.co/rS7XyqAjm3

Amazon's first operational Kuiper broadband satellites are finally in orbit, but they're gonna need some relief from the FCC on network authorization. https://t.co/MWRbiu6rJW
