Amazing, SpaceX's busy launching satellites
In alt.astronomy a425couple wrote:
SpaceX's fifth Falcon 9 launch in a little more than three weeks
delivered 52 more Starlink internet satellites and two small hitchhiker
payloads to orbit after a booming blastoff from the Kennedy Space Center
in Florida on Saturday evening.
Around eight minutes after launch, the Falcon 9's reusable booster
descended to a bullseye landing on SpaceX's drone ship in the Atlantic
Ocean. It was the eighth trip to space for this booster.

watch the perfect landing so it can be reused!
I think the TV said there was a reuse record as well.
The Falcon 1st stange hit its 10th trip.
That's pretty amazing in itself.
In quantum field theory, the Casimir effect and the Casimir-Polder force are
physical forces arising from a quantized field. They are named after the
Dutch physicist Hendrik Casimir.
Although the Casimir effect can be expressed in terms of virtual particles
interacting with the objects, it is best described and more easily
calculated in terms of the zero-point energy of a quantized field in the
intervening space between the objects.
Because the strength of the force falls off rapidly with distance, it is
measurable only when the distance between the objects is extremely small. On
a submicron scale, this force becomes so strong that it becomes the dominant
force between uncharged conductors. In fact, at separations of 10 nm -- about
100 times the typical size of an atom -- the Casimir effect produces the
equivalent of about 1 atmosphere of pressure (the precise value depending on
surface geometry and other factors).
[A project I worked on 5y back aimed to produce an E**2 drive
using Casimir energy boosting scrounged ions as working fluid.
Pretty small thust but runs "forever". ]
