And here we go..



Hey Astro, in the movie, a missile hitting a satellite caused this chain reaction, is it possible in real life?

Aren’t we just so amazingly lucky that they collide over nothing.

It wouldn't matter if they collided over New York City. The debris doesn't just stop and drop straight down. That's not how this works.

Interesting.

Not falling straight down after a collision at an altitude of 550+ miles...

The last thing we need is another cloud of debris on a slow path to decay and reentry jeopardizing other flights.

Good Evening Mr. Astromut. This is probably not the first time things have collided up there. Does Earth have space junk rings around it like Saturn does, yet?

Re: Possible satellite collision on Thursday night
Hey Astro a year or so ago I was at work and it was about 4:00 in the morning and I was outside. I happened to look straight above me just as the prettiest green ball of fire flew over my head and across the sky. It doesn't even seem real it happened so fast. What was the green fireball if you don't mind me asking? I'm assuming you do, I'm sorry if I'm being presumptuous.

And no one ever walked on the moon!
 Quoting: Anonymous Coward 79489165


Yes they did. Fuck off.
 Quoting: Astromut

Did they have to pass through the Van Allen belt? If so how were they able to do that since I just watched a video from NASA that stated they are just now able to pass through it (5 years ago)? Just curious.
 Quoting: Follower of Jesus


EFT-1 flew through a much more intense portion of the belts for longer than Apollo did. I've explained this for years now.
Except Van Allen radiation belt...and stuff.
 Quoting: The Wizzard of Ahs!


Here is a plot of how much radiation the astronauts would be expected to receive given Apollo 11's trajectory to the moon, one way. Apollo had an areal density equivalent to about 7~8 g/cm^2:
[link to drive.google.com (secure)]
Less than 1 rad each way, it's harmless, the trapped proton dose from the Van Allen belts is less than a tenth of a rad (so even with the Q factor discussed below, less than a rem of VAB radiation).

By way of comparison, here is the dose you would receive in an Apollo capsule flying the same trajectory as Orion EFT-1's final orbit (though with a slightly higher perigee, SPENVIS won't let you calculate trajectories that go through the atmosphere):
[link to drive.google.com (secure)]
Here's a map of the orbit:
[link to drive.google.com (secure)]
Nearly 10 rads, with the dose almost entirely made up of radiation trapped in the belt. The Q factor on that could be as high as 10 ( [link to www.nrc.gov (secure)] ), so you could be looking at about 100 rem equivalent dose. At that dose with an acute exposure, you're looking at chromosome damage, reduction in white blood cell count, and the onset of radiation sickness within a few hours.

Trajectory matters. Apollo's trajectory was not hazardous to the crew.
 Quoting: Dr. Deplorable Astromut



Now can we stop derailing this thread by asking me questions I've debunked a thousand times to do with Apollo and having nothing at all to do with this thread?

Ok... three tons of junk may fall on the Antarctica? Any concerns here?
 Quoting: GlobalExodus


That's not how this works. Just because they collide doesn't mean the debris all rains down at the sub satellite point of the collision. In fact much of it will remain in orbit for years to come if that were to happen and pose a collision threat to other low orbit satellites. Some of it may end up on an immediate suborbital trajectory, but that does not mean it automatically lands in Antarctica. Some of it could even re-enter half an orbit later on the other side of the world.

As if there wasn't enough junk floating around up there already.

Just a heads up. Both are defunct, one is a Chinese rocket stage from 2009, the other is an old Russian satellite launched in 1989.

 Quoting: Anonymous Coward 79416228


Exactly...

What's the odds that this 1989 Russian Satellite have a nuclear reactor on board. Those Crazy Russians like to put nukes on everything...

Imagine the nuke reactor going critical as it smashes into the Chinese booster rocket. Imagine that reactor striking the Earth and raining down nuclear debris...

ahhh
 Quoting: DuckNCover


There's no way yet to place a nuclear reactor in space because they need water, all nuclear power plants are located near sea shore ,lakes or rivers. Nuclear reactors are actually working like any other power plant,using coal, gas, oil,,, but is using the thermal energy emitted by nuclear reaction to heat water turn it into steams expands in a turbine which powers the generator.
We split to atom but still use it to boil water; this is why nuclear power was only installed on ships ,aircraft carriers, subs, Russian icebreakers.
But you are right , radioisotope thermoelectric generator using radioactive plutonium were installed on early satellites and still used on space probes that move to far away from Sun to use solar panels. Like Voyager,Cassini and even Appolo mission, one of this crashed in pacific with Apollo 13. But these power cells are not using large amount of radioactive material, i remember reading that this kind of long lasting batteries with plutonium were used in heart peacemakers and implanted in many patients back in 70s, until they figure out that after the patient dies would turn into a dirty bomb during cremation.

Just an article in the New Yorker about this. You got to read everything to get the truth. Talked about the problems and how NASA really doesn't care. ESA is doing more about trying to clean things up.

what height would these projectiles after explosion hang out at for a bit Astro ?

anything else going to get hit due to this ?

So it looks likely that one of the satellites will be 'visible' to the KSR pre close approach and the other post close approach. Interesting

Re: Possible satellite collision on Thursday night
this could mean DOOM . i recently watched a documentary about how much space debries is in the layer of space where satelites are . and because when a satellite life is ended , it remains there just floating around eventually earths amtosphere will be full of debries ..

anyway long story short if the 2 satellites collide , they will produce a lot of debrie that could hit other satellites and so on eventually all satellites will be down and we will have no more satellite communication

i dont even remember where i heard it as there were three channels at the tine and no internet, and i didnt watch much tv as a kid..

but i remember thinking it was going going to crash out in our yard and i kept looking for it..

i guess i was 6 at the time,.i just looked it up..
lol

still have no idea how i found about it at that age and why i thought it would be cool crashing down in the creek behind my house


anyway. keep us posted
