How Do Starlink Satellites Navigate To Their Final Operational Orbits
Posted by Alan Jurisson in categories: internet, mapping, satellites
When SpaceX deploy batches of Starlink satellites they drop them off in lower orbits and expect the satellites themselves to navigate towards their final operational orbits. This is quite a complex process and one that’s worth discussing, the satellites need to be able to reach the target orbital plane, raise the orbit to operational altitude, and then finally maneuver to a specific slot within that plane before they become operational.

On the Shoulders of Giants: Steven Weinberg and the Quest to Explain the World
Posted by Alan Jurisson in category: particle physics
Nobel laureate Steven Weinberg was one of the world’s foremost theoretical physicists and a passionate advocate for science. Among his many influential contributions is the co-discovery of the electroweak theory that unifies electromagnetism and the weak nuclear force, a central pillar in the Standard Model of Particle Physics. Join Brian Greene and physicist John Preskill as they pay tribute to Steven Weinberg and his profound contributions to science.

Starship: I can’t wait to see another successful touchdown
Posted by Heather Blevins in category: space travel
According to Musk, “Starbase is moving at Warp 9” as SpaceX prepare for the first orbital demonstration of the Starship/Super Heavy stack. It is going to be an absolute monster topping out at 120 meters, almost 10 meters taller than the mighty Saturn V.
Although largely a demonstration mission, Musk has said that it will carry a “wheel of cheese.” This was also the first payload of the company’s Dragon spacecraft. It was chosen because it was the silliest thing they could imagine.
