<div><font face="Arial" size="2">I'm not sure about the moon-quake seismograph on
moon. I've not heard anything about it recently. I would expect if it did
find something we would hear about it. The Impact itself is not particularly large, I
would describe it as "medium" size impact. The craft with a weight of about 2.6
tonne is around the same weight as an asteroid 1 - 2 metres in diameter. NASA
only tracks asteroids of km size, so we don't know how many impacts of this size
would actually occur. What is special about this impact is we knew exactly when
& where to watch. With an asteroid we don't have that info. </font><font face="Arial" size="2">In the 1960's the Russian's crashed several "Luna" space craft
into moon.</font></div>

<div><font face="Arial" size="2">All these impacts would have a very small effect on
the orbit. The mass of the moon is about 7 x 10 raised to 22 power. This means
the moon is 19˝ orders of magnitude larger than the space craft.</font></div>

<div><br></div>Good question .. I bet the climate change deniers will make
whatever mileage they can from the paperclip variation in the moons orbit that
is detected and the need for further research. The reality is that any
variation in the orbit started long before the crash as the satellite and moon
began their joint orbital dance of death.<br><br>There is a moon-quake
seismograph on the moon left after the Apollo missions. They did use this to
detect the empty Apollo lander craft that crashed onto the moon after the
impacted the surface. I am curious if it is still working (albeit it may no
longer be working) <br><br>I will run both thoughts past a good friend of
mine, Ross who has a sound physics background and is president of the ASV
cosmological society.<br><br>Regards Roland<br><br>

any).<br> <a href="http://spaceweather.com/" target="_blank">http://spaceweather.com/</a><br><br>At least my WA friends
will not have to stay up as late as I must in Melbourne to glimpse of the
Japanese Spacecraft that is predicted to impact on the lunar surface. I will
be poking my head outside with a telescope and battle the clouds and cold to
spot the lunar impact on the top LHS (turning their diagram upside down for
the southern hemisphere) From my copy of the open source software
Stellarium, the Moon will be to the NE and about 80 degrees high (just look
up .. no need to use the sofware like I did!) <br><br>This makes the impact
time for Melbourne: Thursday, June 11, 2009 at 4:30:00 AM or Perth Thursday,
June 11, 2009 at 2:30:00 AM<br><br>As my wife points out, the last time she
looked at space junk in WA, it was Skylab with no space repellent to keep
the debris away. Dont expect any debris clouds spiraling back or blinding
flash... just a vague chance of spotting something through binoculars or
largish telescope. We lost ours with the Gippsland bush fires that ran
through our school camp back in February so I am relying on one that a
friend loaned me. Fingers crossed .. </span></font></p>
<p><font face="Times New Roman" size="3"><span style="font-size: 12pt;">Kaguya
is a big spaceship. It masses 2,900 kg and will hit the Moon at an oblique
angle traveling approximately 6,000 km/hr. Whether it tumbles and bounces
along the lunar surface or runs headlong into some towering crater wall, no
one can say. Clues to the end of Kaguya will come on June 10th in the form
of an explosive flash (or lack thereof) and high-res images of the crash
site taken by future lunar orbiters.</span></font></p>

Kaguya will crash into the Moon on Wednesday, June 10th, around 1830 UT. The
timing favors observers in Asia and Australia, who might be able to see a
flash of light or a plume of debris rising from the Moon's southeastern
limb. The spacecraft masses 2,600 kg and it will slam into the lunar
surface at 6,000 km/hr. No one knows, however, how bright the flash
might be or whether it will be visible even through large telescopes.
