NASA bomb moon to find water

If its a clear sky I'll try to record on my scope, assuming the explosion will be visible?
 
As a result of the Trajectory Correction Manoeuvre the exact impact times are:

Centaur - 12:31:19 BST

Shepherding craft - 12:35:45 BST

That does depend on whether you are able to see the lunar south pole at the time of impact.

It will be lunchtime here when it happens so I doubt it. This link pretty much confirms it:

I'm not going to see it :( I assumed when it said 9pm it ment BMT.

It would have been fun to try and catch that with your telescope but c’est la vie. I’m sure we will see some quite spectacular images from observatories that can see the event. :)
 
Not really to be honest, lives are lost by the thousands every day, lets be honest, building a completely replairable, replacements for every part ship that can make the journey there and back, WILL NEVER HAPPEN. You can't expect every unexpected outcome. Because what if they make that filter repairable, and they put 15 spares in, but they needed a 16th.

Very nicely constructed post, except you completely missed the point. The problem isn't covering every option - it's about covering the likely ones. Filters get clogged by design - that's what they are there for. So why include a filter that you can't replace at all? In your example, they could simply choose to run the equipment without the filter, but that isn't an option if you can't get at the old filter in the first place.

Anyway, on to LCROSS, as that's what this is about. I will - of course - be watching NASA TV. And Sky News and/or the BBC may cover the time immediately adjacant to the impact too.

Here's a complete run-down of events leading up to impact:

09:00 BST Thursday: Final orbit determination delivery for Separation.
14:00 BST: Separation Activity Selection Review (ASR)
15:00 BST: Command generation and checking for Separation through Braking Burn.
20:00 BST: Separation Command Approval Meeting (CAM).

21:30 BST: Command loads for Separation, Centaur Observation and Braking Burn, and slow rotation to Separation attitude.
~01:00 BST Friday: Slow rotation to Separation attitude starts.
02:40 BST: Separation onboard command sequence starts.
02:50 BST: Separation.
02:51 BST: Flip to point LCROSS instruments at Centaur.
03:01 BST: End of Centaur Observation.
03:30 BST: Braking Burn starts.
~04:00 BST: Preliminary Impact command load.
05:30 BST: Final Orbit Determination Delivery.
07:30 BST: Disabling LCROSS Fault Management.
09:30 BST: Impact Command Approval Meeting (CAM).
10:00 BST: Loading Impact command sequence to LCROSS.
11:00 BST: Start of Impact onboard command sequence.
11:10 BST: Switch to –Z MGA.
11:15 BST: Transitioning to Science Rate.
11:36 BST: Payload powers on.
12:10 BST: TLP Instrument powers on.
12:30:20 BST: Flash Mode begins.
12:31:20 BST: Centaur Impact.
12:31:23 BST: Curtain Mode begins.
12:34:23 BST: Crater Mode begins.
12:35:39 BST: Shepherding Spacecraft impact.
