Explosion on the moon

Meteorite hits the moon, how cool is that?

I like the moon

I saw that new sitem the other day. The impact was spotted because NASA are studying the moon properly again for the first time in over 30 years.

Yes, clearly the risks of being hit by space dust/debris is far greater on the moon, because there's no atmosphere. During the Leonids, or some such, there can be thousands of meteors per hour. I'm curious what would happen if one of the dust particles hit something man made! I reckon it would make a bit of a dent, because of the huge velocities involved!

We'll have to wait for the sunday sport to
verify that both the face od Elvis, and the bomber/bus are intact

failing that, perhaps........

Check out the shadows

[srebbe64]

And why aren't there any stars?

[rich 36]

D' you know, thats an excellent question,
and one, the so-called 'moonies' scattered about here,
should easilly be able to answer.


they'll perhaps be along in a minute

What's wrong with the shadows?

Can you see stars in daylight on earth?

[lazyitus]

The sun was the other side of the moon, ensuring no light was able to illuminate the stars that could normally be seen from this angle.

Aye, your average random 'sporadic' meteor hits our atmosphere at about 20 km/s, Taurids are quicker at about 30 km/s but to get a decent buttonhole in your space suit you need a Leonid at 70 km/s, ouch.

Hmmmmm......taurid slams into the moon, eh?

Trust the beeb to have an artist up there to record it.........I'm impressed.

No because of the atmosphere - but there is none on the moon.

Yeah, but the artist included stars!

Exposure issues



or an anomaly in D o F ?

BBC News website said:

The blast was equal in energy to about 70kg of TNT and was seen near the edge of Mare Imbrium

BBC News website also said:

One of the astronomers who observed the impact estimates that it gouged a crater 3m wide and 0.4m deep

Now I'm not an expert on explosives, but surely 70 kilo's of TNT would make a crater somewhat larger than 3 by 0.4 metres?









Standing by to be proven wrong

[likesbikes]

Incidentally, of course it wasn't a hoax. Otherwise where would cheese come from?

[RichUK]

I'm not an expert, but surely there would be no explosion, as there is no atmosphere to fuel the fire. So it might just be a large impact.

I'll wait to be corrected by an astro physicist.

loks more vivd in
'real life'

I'm sure we all agree,

I looks like the astronaught is bump starting his moon buggy to me!
