Interesting story on the BBC Site: www.bbc.co.uk/news/science-environment-16869022Looking forward to seeing some good science from this - but how long will it be before the HBs start questioning why it can't see anything on the Moon...?

On the subject of orbital mechanics and so on, would it be a good time to mention "To Rise From Earth"? No maths but simple, straightforward explanations and excellent diagrams. I'd recommend it as a good place to start, what do you folks think?

now let me ask again how did the mylar film not get damaged by the 1000 degree rocket stream as the lander touched down on the moon? Could you explain why you think it should, bearing in mind the points made earlier in the thread about the way fluids move?

To add my two-penn'orth to the oxidiser/fuel debate, how about this site: www.ehartwell.com/LM//SCATSystems.htmScroll down to the propulsion systems sections. A good read, that whole site.

Unlimited tests - no thank you. Too much of a drag, for both players and spectators. Having a time or run limit puts just enough pressure on the teams to make them stretch themselves and do their utmost - makes for much better cricket.

Interesting article from the BBC here: www.bbc.co.uk/news/science-environment-14580995For those who work in the industry - how do you shield against this sort of thing when you are designing/building a spacecraft, and what's the knock-on effect? Presumably there's a payload hit if you're using heavier materials...

I'm currently trying to do an Open University course in Physical Sciences - even the cost of those courses has gone up, to the point where I may not be able to finish. There are transitional arrangements in place until 2017. I'd heard of those - haven't delved into the details yet. Fingers crossed... Apologies if too far off topic.....

Found this on the BBC site - sounds intriguing. www.bbc.co.uk/news/science-environment-14405122Could a Star Trek-style matter/antimatter propulsion system be a step closer? Not saying FTL but just the energy-production side. How you'd harvest and use the antiprotons would be an interesting problem, but stranger things have happened.

mopc, one of the links at the bottom of this page is to the Apollo Lunar Surface Journal. In there, amongst other things, you will find an awful lot of Apollo photographs. I would suggest you browse for a while and you may find you can answer your own question.

Fattydash, please demonstrate that Luna 15 had the ability to photograph the proposed/actual Apollo 11 landing site with sufficient resolution to cast doubt on the veracity of the NASA CLAIMS. This has been asked before, but I've seen no reply as yet.

I've read inconceivable's post a few times now, and I can't get past the "whaaa?" reaction. What on Earth (or the Moon) is he on about? Come on, inconceivable, please explain the background to this odd query.
