What goes up , might not be a downer

Well, not as much of one.

What, exactly, makes a rocket fuel environmentally friendly?

I think, as with many headlines, adding an 'er' might be more accurate.

But any step in the right direction must be welcome.

At least it seems a tad more credible than some of the claims made by such as Virgin Galactic (and which have attracted a few eyebrow cranks of mine).

Exploration is necessary, so mitigating the consequences is the best option.

Look out Kermit!

These are early days PR punts I'm guessing, so I won't accord them fully fledged category status as yet, but looks like your pond is a teeming fuel dump:

Indy - How to turn water into rocket fuel – scientists unlock power of the sun

Guardian - 'Oil from algae' promises climate friendly fuel

Both interesting, but also sort of focusing still on our desire to still combust, ultimately, rather than doing it less and less.

Still, it's nice to get a space story in without it being a major green eyebrow crank.
