Enceladus

Is it the most likely place to look for life in the solar system? I know that Carolyn Porco thinks so. Or at least that it’s a better prospect than Europa. Plus, we haven’t been warned to attempt no landings there.

It’s obviously a lot harder mission than Europa, but it seems like going to Europa to look for life instead of Enceladus is like the guy who went to a different block to look for his lost car keys because the light was better there.

Falcon Heavy

This should be easy, they said. Just glue three Falcon 9s together, they said:

Musk said the rocket cores for Falcon Heavy’s first flight are two to three months away from completion. He emphasized that the first launch will carry a lot of risk, and as such, SpaceX doesn’t plan to carry a valuable payload or payloads with it.

“We will probably fly something really silly on Falcon Heavy because it is quite a high risk mission,” he said.

I’m glad to see that they’re finally coming close. It’s an important development, both technically and politically. Also, the claimed LEO payload is now up to 64 tonnes, so it’s almost the capability of SLS Block 1B.

If we want bigger telescopes or to go to Mars, we need heavy lift, “experts” say.

Nonsense.

Graphene

Is there anything it can’t do? OK, probably, but this is pretty cool:

“Realization of scalable membranes with uniform pore size down to atomic scale is a significant step forward and will open new possibilities for improving the efficiency of desalination technology,” Rahul Nair, professor of material physics at the University of Manchester, said in a statement.

Previously researchers were unable to remove common salts using the graphene filtering technique, instead removing small nanoparticles and organic molecules.

“This is the first clear-cut experiment in this regime. We also demonstrate that there are realistic possibilities to scale up the described approach and mass produce graphene-based membranes with required sleeve sizes,” Nair added.

It will probably have useful purefying properties in general, but this would be useful for California as well as the Third World.
