Space Launch
Re: Space Launch
Is that the end of innovation in launches? Keep this basic set up for a couple of centuries?
Why bother with space planes? Why bother with dropping rockets from aircraft?

Re: Space Launch
Indeed, the main point of space planes was reusability, the main point of launching from aircraft is reducing fuel requirements.
However the “Starship” could be a big step again.

My avatar was a scientific result that was later found to be 'mistaken' - I rarely claim to be 100% correct
ETA 5/8/20: I've been advised that the result was correct, it was the initial interpretation that needed to be withdrawn
Meta? I'd say so!

Re: Space Launch
Smooth as anything. I’ve not watched a docking before, didn’t realise it took so long between the docking and the hatch open.

Re: Space Launch
So the cause of Rocketlab's Electron rocket failure on July 4th has been identified. In the past, the media would have just left it at "electrical fault" but these days we get all the technical details we crave.
Electron uses electric motors to pump the fuel and oxidiser into the combustion chambers. Even with its substantial power requirements, it is surprising that a connection would heat itself up that quickly given the rocket's short life.Rocket Lab said its team “was able to confidently narrow the issue down to a single anomalous electrical connection.”
“This connection was intermittently secure through flight, creating increasing resistance that caused heating and thermal expansion in the electrical component,” Rocket Lab said. “This caused the surrounding potting compounds to liquify, leading to the disconnection of the electrical system and subsequent engine shutdown.”“The liquefaction of this potting compound is a result of the additional heat caused by the resistance,” Beck explained. “When those potting compounds are able to flow, it doesn’t create great electrical connections.”

They should be on their way back at some point soon.
having that swing is a necessary but not sufficient condition for it meaning a thing

Re: Space Launch
If it was intermittently connected it was probably arcing when almost connected, causing quite a bit of heat. I had a similar problem with a circuit breaker on the main board of my house, much scorching.Pishwish wrote: ↑Sat Aug 01, 2020 8:17 pmSo the cause of Rocketlab's Electron rocket failure on July 4th has been identified.

Have you considered stupidity as an explanation
