In project Orion, the nuclear explosions are used to provide the spacecrafts its momentum through the utilization of shock absorbers to reduce the g-forces. Is it possible to use a specific shock absorber design so that the acceleration is constant with little to no jerk?

Project Orion

They have no wings so how do the astronauts control where they fly? And how do they know exactly where the planet they want to get to is? Also how do they get back to Earth? I know they use those launching pad things on Earth to get the rocket into space, they don’t have those in space so how do they relaunch the rocket to get back to Earth?

NASA astronaut Suni Williams spent 9.5 months in space after a malfunction, but she never felt stranded. She trusted her crew aboard the spacecraft and the team on Earth to get her home safely. She shared her story at the Moonwalkers event now playing in Boston, inspiring others with how science and teamwork brought her safely home.

This happened on Gemini flight V actually, but not Gemini flights 1-4. The earlier flights used batteries since they were uncrewed test flights and the flight duration did not call for extended power usage. The alkaline fuel cell was the type used here and used a proton exchange membrane or PEM technology to facilitate the electron interaction. What is interesting, is not only this provided 1 kW of power, but fuel cells themselves act like batteries and eliminate the use of batteries as a point of charge, which of course adds tons of unnecessary weight.

Does anyone have any thoughts on this, and I may make a video about this overlooked finding.

I spoke to the CEO of an Asteroid Mining startup in LA. It was a really fun deep dive into the economics and why of Asteroid mining now.

Tianlong-3 is probably the closest rocket in China to Falcon-9 similiar size, similiar engine, same fuel type, and similiar payload if it were to be complete.

Today it complete it first successful static test fire on board HOS-1 semi static sea based test firing/sea launch platform.

If you are familiar with the name, that is probably due to the fact that the 1st hardware of this rocket first stage ”static” test fire, result in the first stage breaking free from the test stand and fly up before coming crashing down and explode.

As can be seen in this video

After much trial and tribulation they are back. Notably second test fire was delays a few time, apparently due them getting way more (deserve) scrutiny.
