Space and Stuff : It's Big

[Pootsy]

One theory is you have a big shield in front of you, the cheapest way is to have a big block of frozen water...  no negligible drag in a vacuum...as an ablative

How would we get a giant ice shield into space. Obviously as water it will be extremely heavy. You can't just float it up. Then trying to shape water as it turns to ice very quickly due to the low temps in space. Also keeping it frozen with the oscillation in temps in space.

Nasa beams cat video from deep space with laser

The ultra HD footage of Taters the cat was sent as the agency tries to improve space communications.

Were they sure about this?! If this video does manage to make its way to an alien life form, we might be sending them the impression that there’s a bunch of pussies living on this planet.
Might make us ripe for an invasion!

If youve got the power to go that fast that you need a shield - you have the power to carry the water up from the ground

Obviously as water it will be extremely heavy. You can't just float it up. Then trying to shape water as it turns to ice very quickly due to the low temps in space.

I'm a big picture guy...details are for the pointy heads to work out

Also keeping it frozen with the oscillation in temps in space.

What oscillations - it a vacuum, the temperature is just cold or colder, there is negligible friction too.
If you're near enough to a star to absorb real heat - you won't be going that fast to need a shield.

Edit; you make the ice in the ship, bucky ball shaped Heptagonal and Hexagonal and fit them together like the panels on a ️

Arthur C Clarke had this as a plot device in his novel The Songs of Distant Earth.

I read the book years ago, but I saw it somewhere else, they pinched it off him?

He came up with many concept ideas

The concept of satellite communication too. Way ahead of his time ..

'Clarke orbit'.

The book also has a space elevator something else credited to him, from an earlier book Fountains of Paradise.

The classic age of sci-fi had so much published that I'm sure the origin of a lot of the ideas might be hard to trace so whether the ice was him or someone else previously I'm not sure. Either way Clarke certainly possessed a very inventive mind.

This week's The Rest is Politics Leading podcast is with Tim Peake. Interesting listen about his career and the future of manned space exploration.

Amazing images from James Webb telescope, two years after launch - BBC News

The most powerful observatory ever put in space is performing better than anyone could have imagined.

Missus d got me his book for chrimbo, really looking forward to reading that.

They'd be right and most of them post endlessly in the 10 point deduction thread.

Came to London specifically to see the Apollo 10 Command Module at the Science Museum, the only CM not on US soil.

This mission was the dress rehearsal for Apollo 11 a few months later. Tom Stafford and Gene Cernan flew their Lunar Module to within 14kms of the Moon’s surface while John Young remained alone aboard the CM.

Young and Cernan later walked on the Moon as commanders of Apollos 16 & 17 respectively.

That's a new way of measuring. lol
