It's all about the Van Allen Radiation belt. Nothing new.

Didn't Dr Van Allen say there was nothing wrong with his belt , something to do with the " Rainbow " test series that Hawaii " enjoyed " ;-) , another " famous / infamous " f up by the US Military but NOT half as good as " castle Bravo hahahahaha ;-) ;-)

If you have something positive to contribute, say it otherwise say nothing.

Quoting your own words: - I repeat things as there are many new members & they "may" not know about it.

There are many who do know about things but with the various issues that take up one's time in life, keeping up to date is not always possible, so when threads like this crop up, it is one way to keep up to date & secondly many may find it interesting.

I find it truly amazing that one who is involved in a space related science project is so negative about both space & science, so amazing, it makes one wonder why they're here!

I think you mean the Starfish Prime test which was one of five high-altitude tests grouped together as Operation Fishbowl.


Yea that's the one " wotever ;-) " can't be 100% perfect 100% of the time like so many posters are now can i ;-)

still the " St's" f-up fairly well didn't they let alone the booms as their missiles exploded on the pads and contaminated sh#tloads of land to ;-)

Assuming this man made bubble surrounding the earth has been verified and that it deflects cosmic rays and other harmful radiation, I wonder if the technology can be modified to generate a bubble around a manned spacecraft. Or would it require cosmic power levels to be effective, also requiring the spacecraft to be impossibly large.

but until we invent the warp drive for FLT travel, I doubt shields will be needed. Interesting thought though!


What about when there's Crewed mission to Mars , that is sposed to be happening fairly soon ain't it ?? ( pending on money / politics stuff etc ) . Would of 4t if they can develop " shielding tech " it would save a lot of weight in the space craft and weight is what they don't want int it ? More weight = more fuel etc .
Might not be faster than light but deflecting a micro meteorite would save lives / craft .
They have to move the ISS to stop it getting " holed " by objects / debris and space junk
Think if anything puts a hole into anything in space it's " sh#t your spacesuit " time for the Astronaughts / Cosmonaughts etc till they have repaired the damage caused

Something akin to the Startrek shields around Enterprise? This was 24th Century sci fi technology, but until we invent the warp drive for FLT travel, I doubt shields will be needed

Many think cosmic radiation will prove to be a real problem for deep space travel.

Yes Thats very true.
If I remember right and the Apollo projects sending mans to our Moon there was a major sunburst.
Luckily it was between the missions.

And that's not even deep space travel...

Message 1868415 - Posted: 20 May 2017, 16:31:52 UTC - in response to Message 1868411.  

We don't really know what is out there between the stars.


We do know with some certainty of the density of interstellar and even intergalactic hydrogen from Gaussian absorption spectra near the 21cm neutral hydrogen band. It's about 1 atom/cc. If we plan on traveling near lightspeed, these normally harmless atoms are going to become the cosmic rays, and will require shielding of a technological level beyond what we are currently capable.

The hypothetical Bussard ramjet would of course take care of two issues by both removing these atoms and using them as fusion fuel.

So you are talking the year 3000 onwards?

Year 3000 ?
On what planet do you live on?
Our universe is about 13 BILLIONS old.
Our planet is about 4 BILLIONS old.
Myself? About 60 years.
Almost old like you are:)

I was thinking about using the VLF bubble concept for trips around the solar system within the next 100 years or so to protect against radiation, both cosmic and solar.

Protection against radiation, both cosmic and solar, are very tricky when sending men/women into space.
But it's doable.
It only takes taxpayers money to do it.
One dollar per year perhaps?

Certainly within our solar system and between the planets that might be feasible

Probably necessary.
but I think science would need to take some big leaps forward from our current knowledge to achieve that within the next 100 years.

The technology exists here as the title to the thread states.
But yes if we did, then the stars could very well beckon. But not in our lifetimes I would think!

How true. Our solar system could keep us busy for the imaginable future.
