Re: SpaceX News

One final bit of info. SuperDraco is derived from Draco, and utilizes the same storable (non-cryogenic) propellant as the small Draco thrusters, but are over 100 times larger in terms of delivered thrust. The Draco thrusters were tested earlier in the day No conclusions or correlations just facts to...

Back to Apollo days : Three of those failed while they were installed in the spacecraft, two during a system test, and one, of course, was Apollo 13, as everybody is probably familiar.

Re: SpaceX News

The engines burn hypergolic propellants—monomethylhydrazine is the fuel while nitrogen tetroxide is the oxidizer. These are fairly toxic compounds, but unlike other "cleaner" rocket fuels, they are more easily storable both on the ground and in space. COPV seem to fail when exposed to cryo...

Re: SpaceX News

There is a download on Google documents and you can reach the link on the Reddit space X forum that someone is broken down the explosion into 200 clips in PNG format. Detail is very grainy and unfortunately at the rate of explosion it only takes three frames to cover the entire craft. It is obvious ...

Re: Thermal battery with 6-8 times the energy density of lithium

Climate Change Technologies, also known as CCT Energy Storage, has launched its TED (Thermal Energy Device) with a set of remarkable claims. Remarkable claims require remarkable proof. I have yet to see either in this case. Pumped hydro still remains the cheapest most economical way to store energy....

Nearly one third of the Ming dynasty-era (1368–1644) wall has disappeared, and officials blame environmental causes and human damage. China’s Great Wall Society h...

Re: Sell The Whitehouse to Trump

The marine's have already openly made clear that this action will have a adverse impact on readiness.

This is dandelion fluff. sounds very good at first until you look at the hard logistics of building where there was no infrastructure in the first place. then you need users of that infrastructure distributed along that border. most of the southern border is wilderness, the reason we did not build a...
