Possible satellite collision on Thursday night

And no one ever walked on the moon!

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.

Is there a risk this could trigger a Kessler effect?

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.

Thanks for the heads up Astro. Do you think that any collision of these two would be observable in any way?

Yes they did. Fuck off.

Can you see the mirror trough your telescope? Can you take a picture for us?

This thread has nothing to do with Apollo and no telescope on Earth can resolve anything left on the moon. Only telescopes orbiting the moon can do that. Stop trying to derail the thread you idiots.

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

I couldn't help but find your response there a bit humorous, as though you have to deal with that kind of thing pretty often. I appreciate your threads, interesting stuff.

No they didn't

They never ever show a rocket going all the way up. They always cut to a camera that's strapped on the side, which makes it easy to fake the entire thing. Show me footage from another rocket trailing the main one all the way into "space"

You can't provide that. So it's all bullshit.

Why doesnt NASA make a maneuverable orbiting space vacuum to suck up all the space junk instead of wasting billions on a boring space station?

You are a rude, nasty mother fucker!!!! Always were. Dick

That doesn't prove it's real

It's not showing the thing going all the way into space

Epic fail

False. I've shown it going all the way to space and coming back to land in one continuous shot.

You are a liar and you are banned from my threads. Stop trespassing.

You are a rude, nasty mother fucker!!!! Always were. Dick

Lmao you're so mad.

You didn't prove a thing pal. You shooting the thing from the ground doesn't prove how far up it went. Absolute epic fail.

No metal frame, no apparatus at all, just a rocket working in space:

Measurements made from the video indicate that the booster is above the Karman line and in space during the boostback burn. My telescope has an altitude dial on the side which was previously recorded using a gopro during launch. From my launch viewing site, the telescope is angled up about 40 degrees above the horizon during the boostback burn. This sped-up video is zoomed in the altitude dial, apologies the resolution isn't good enough to read the numbers but you can see where the numbers are marked and they're in 10 degree increments, the video starts at launch (0 degrees) and ends at the end of the boostback burn (40 degrees):

At launch the Falcon boosters are about 22 pixels wide in my camera:

I'm 21.1 km from the launch site and the boosters are each 3.7 meters wide, so that corresponds to an angular size of 0.01 degrees. By the end of the boostback they're only about 3.2 pixels wide:

Given that we know from the launch that a 3.7 meter wide booster is 22 pixels wide in the view from 21.1 km, that means a pixel size of 3.2 pixels corresponds to an angular size of about 0.00146 degrees. The range between my telescope and the booster is therefore about 145 km at that time. Given that it's about 40 degrees above the horizon, then even if we assume a flat earth the altitude above the ground of the booster was roughly 122 km. Let's be generous here and say I could be about 5 degrees off on either side of that 40 degree measurement. Even at 35 degrees above the horizon the altitude (even assuming a flat earth) would be 102 km. At 45 degrees it would of course be 145 km above the earth. So it was somewhere between about 102 - 145 km in altitude, above the Karman line and in space. My video indicates it had no trouble reversing course to come back and land near the launch site. Please show your evidence that the video indicates it was not in space.

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

This has all of the stink of a FF!

If we start hearing about the Kessler syndrome, something might be about to touch off....

Interesting and thank you Astro!
