The "Focused Energy" approach to direct-drive, 'hotspot' fast ignition for fusion: link.springer.com/article/10.100… It avoids both the -90% energy loss from hohlraum designs, and reduces the initial pulse of energy that needs to be delivered to just 10-20 kJ.
In low Earth orbit atomic oxygen can slowly erode some materials, like the mylar in these experiments which were supposed to collect heavier ions.

The centers of most galaxies contain a supermassive black hole, and they are monstrous. In the Milky Way, we have one called Sagittarius A*. We know it's located at the center of our galaxy because we can see a number of stars being thrown around by a seemingly empty spot.

Hello,everyone.I'm a student and i very interest in making CG about space artifact. This is my concept design about a Transport space stastion in 2250s. Here are some picture of my space station.😃 Space station's name:No.8 Earth System Transport Station "Gateway to East-Asia".
“Let’s throw a probe out to Jupiter, so Jupiter can throw it into the sun, so the sun can throw it outwards so fast that it can catch up to oumuamua” Easily an S-Teir mission
@DJSnM @ThePrimalDino Yes, sir….familiar with the physics of how it works, but actually doing it is a whole other thing. Impressive timing and pointing!
@smartereveryday @ThePrimalDino So for example Escape velocity at 0.01AU is ~420km/sec, and each 1m/s beyond that gets you 916m/sec hyperbolic excess - I.e. velocity infinity. 120m/s dV gets you 10km/sec 475m/s gets you to 20km/sec 1070m/s gets 30km/sec 2865m/s gets 50km/sec You might wonder where the extra…
@smartereveryday @ThePrimalDino It works on the principle of the Oberth effect - a rocket engine adds a specific amount of delta V to the orbital velocity. But the Energy gained is proportional to the orbital velocity. So making it go as fast as possible before firing the engine maximizes the energy gain.
@smartereveryday @ThePrimalDino How close does it get? As close as possible. Basically the closer it is when firing the engines the more excess hypergolic velocity it emerges with. We jokingly call it a solar ‘fry by’.
Patriot's PAC-2, PAC-3, and PAC-3 MSE internals (and some cutaways)
@FlyingMach_5 @ToughSf All of those instabilities show up no matter what config you have sadly! We intentionally do planar experiments to study them more easily.
@ToughSf @FlyingMach_5 It’s important to clarify what we are talking about here. I am talking about percent energy into the HOTSPOT, which actually does ignition. Indirect drive is 1% efficient at that. Also the gains are limited by the assembly method.
@FlyingMach_5 @ToughSf Yup! The laser-target interactions are very challenging and not easy to simulate either. The assumption that >10% of the laser energy will get into the hotspot is a rather optimistic one IMO.
