SpaceX's Starlink launch from Vandenberg is scheduled for today, while several close satellite encounters are monitored.

SpaceX is set to launch another batch of Starlink satellites today from Vandenberg Space Force Base. This launch, part of their ongoing effort to expand global broadband coverage, will add to the 10,658 active Starlink satellites currently in orbit. The launch is scheduled for the afternoon, with the exact timing dependent on weather conditions. For those interested in tracking the deployment and subsequent orbits, the Starlink Tracker provides real-time updates.

Several close approaches between satellites are being closely monitored. Notably, OBJECT A and OBJECT B are predicted to pass within approximately 0.38 km of each other. Such close encounters underscore the importance of tracking and managing space traffic to prevent potential collisions. The Debris Map offers a visual representation of these and other close approaches.

A new millisecond pulsar has been discovered using the Murchison Widefield Array, adding to our understanding of these rapidly rotating neutron stars. Millisecond pulsars are known for their incredibly fast rotation rates, often spinning hundreds of times per second. This discovery could provide insights into the extreme physics governing neutron stars and their environments.

What to Watch

While there are no new launches scheduled in the immediate future, today's Starlink launch is a significant event. Space enthusiasts can follow live coverage and updates via SpaceX's official channels. For a comprehensive view of upcoming launches, the Launch Schedule offers detailed information.
