Amazon bets on Blue Origin and ULA to scale its 3,200-satellite Leo network

Amazon is expanding its satellite program by using both Blue Origin’s New Glenn and ULA’s Vulcan to deploy its Amazon Leo network. After a prior New Glenn upper-stage failure, Blue Origin plans a mission delivering 48 satellites for Amazon as soon as June, with the FAA having closed the investigation and Blue Origin outlining corrective actions. ULA’s Vulcan remains grounded due to booster anomalies, complicating the schedule for future Amazon launches. Amazon has previously relied on Atlas V, Falcon 9, and Ariane 6 and aims to deploy about 3,200 satellites, seeking faster deployment and potential competition to SpaceX’s Starlink, contingent on Vulcan’s recovery and ongoing testing.

Hubble Captures Spiral Galaxy in Lion's Heart

The Hubble Space Telescope captured a stunning image of the spiral galaxy NGC 3370 in Leo, which is crucial for understanding galaxy formation and measuring cosmic distances using Cepheid variables and Type Ia supernovas, helping to refine our knowledge of the universe's expansion.

Catch the Leonid Meteor Shower Despite the Supermoon

The Leonid meteor shower, peaking on November 17, 2024, is expected to be underwhelming due to the bright moonlight from a nearly full moon, which will obscure the view of the meteors. Typically producing 10 to 20 meteors per hour, this year's display is unlikely to be spectacular. The Leonids originate from the debris of the Tempel-Tuttle comet, and while historically capable of producing meteor storms, no unusual activity is forecasted for 2024. Observers are advised to watch in the pre-dawn hours when Leo is visible, despite the challenging conditions.
