NASA live broadcast of LCROSS impact (Probe to Crash Into the Moon)

NASA's Lunar Prospector first detected some hydrogen signatures in craters on the dark side of the moon in 1999. Ever since, researchers have been keen to confirm the presence of water on the moon. The Lunar CRater Observing and Sensing Satellite (LCROSS) is tasked with crashing through the mists of speculation and conjecture and discover the truth. And you can watch all the action as it happens.

LCROSS was launched on June 18th and executed a fly-by of the moon five days later before entering into a wide orbit. On Friday October 9th, the craft will start to make its final approach, not to land but to crash land. The upper stage rocket in front, the Centaur, will separate from LCROSS which will, in turn, slow down a little. Creating a four minute gap between each vessel, the Centaur will crash into the Cabeus crater at the Moon's south pole. The heavy impact will create a great plume of debris.

Following behind, the LCROSS will pass through the debris, collecting and relaying data back to Earth before itself impacting the crater. As well as a visible camera and radiometer, the LCROSS payload also includes two near-infrared spectrometers, a visible light spectrometer, two mid-infrared cameras and two near-infrared cameras.

"As the ejecta rises above the target crater's rim and is exposed to sunlight, any water-ice, hydrocarbons or organics will vaporize and break down into their basic components. These components primarily will be monitored by the visible and infrared spectrometers. The near-infrared and mid-infrared cameras will determine the total amount and distribution of water in the debris plume. The spacecraft's visible camera will track the impact location and the behavior of the debris plume while the visible radiometer will measure the flash created by the Centaur impact," NASA explains in the mission overview.

The good news for all you space fans out there is that NASA will be broadcasting the whole event live on NASA TV. The one and a half hour long show will start at 6:15 am EDT / 3:15 am PDT on Friday October 9th, with the first impact currently scheduled for 7:30 am EDT / 4:30 am PDT.

The broadcast will include live footage from the spacecraft's camera, real-time telemetry based animation, various location clips and (of course, sports fans) live commentary with special guests. For information on how and where to best enjoy the experience, visit NASA's Impact index page.

Final judgment

Hoshana Rabbah is known as the day of the final sealing of judgment, which began on Rosh Hashanah.[1] During the festival of Sukkot the world is judged for water. The seventh day of the festival is the final sealing and since human life depends on water, Hoshana Rabbah is somewhat similar to Yom Kippur. Hence there are additional prayers and requests for repentance as on Yom Kippur.

Why can't any of these things happen in prime time?

Yeah, 4:30 PST is gonna suck. Setting up and aligning the 'scope at 3:30 should be a challenge.

The new Buick LaCrosse and Lucerne are beautiful cars, but I will not buy a Government Motors car. I suspect these two will go the way of Pontiac G8 and the Saturns pretty soon................

So just what have the Mooninites done to NASA? Please,

Personally I think taxpayer funded “prospecting” is a fairly good use of money and its something our government has done to some extent all along.

That said, corporate space start up should be pretty much tax free for any company that actually gets there and shows that profit can be made.

I hope it doesn’t land on little flag that was left in ‘69

Most everyone west of the Mississippi River will be able to see this tomorrow morning if they have access to a moderate sized telescope, weather permitting.

We here will be setting up for this event tonight, and hopefully catch the lunar impact.

On a side note, I obtained this picture of M13 star cluster about a week ago from our backyard location. We are set up more for imaging deep space objects as opposed to brighter objects such as planets and the lunar surface...But we'll give it a go.

M-13 is a Globular star cluster in the Constellation Hercules. This cluster contains several hundred thousand stars, and is approximately 25,000 light years from earth.

Who is there filming it!!!

This is what is making this a really neat event for those that like explosions and large impacts, as many of us do.

There will be the "mother" spacecraft so to speak, releasing the "impactor" as the mother craft films the festivities from above, sending back the impact pics and data, before impacting itself.

It is expected to be large enough impact to be seen with telescopes here on earth, so you can imagine what kind of view the "mother" ship is going to have of the festivities.

Here is the mission overview and impact simulator, it’s a pretty cool short video.

Why ???

If its so important to you researchers to know, spend your own money to find out...

Here is a great video, to answer why, and an overview of the mission, complete with how the mission has unfolded with simulated impact video.

It’s only about a 4 minute video and well worth watching.

I believe the Lewis and Clark expedition is comparable. It was a taxpayer funded mission that included surveying a route west and geological surveying among its goals.

Many at the time called it a colossal waste of taxpayer money not to mention illegal waste of taxpayer money. I believe it was considered a military mission for the purposes of funding it.

I tend to agree. Did you see the mission video at #30?

Yeah. I especially liked this comment.

Clearly the nasa lcross crash action to the moon is astonishingly stupid and arrogant. On all levels this should not be going ahead. Has permission been sought from higher authorities for this.

LOL

Some of the comments we've read, one has to wonder if their serious...Some of these people are suggesting the mission could cause massive earthquakes on the lunar surface, actually breaking the the moon, sending thousands of mountain sized fragments into the earth...

Don't know whether to laugh at these types of comments or have these people put in a rubber room for their own safety...lol

They're sad commentary on the state of science (particularly physics) education in our country, if nothing else. :-/

That's what happens when American hating leftist get a hold of education and the kids ...The kids get stupid and their imaginations shrink.

I feel fortunate, when I was in public schools, they're were enough qualified teachers that cared, that actually spurred the science spark in some of us...

So much so, years later we built this in our backyard, which can be totally remote controlled via computer from inside the home.

Enableing to take images such as this:

Orion Nebula M42 - 1275 lights years from earth.

Orion Nebula M-42 1/30/2009 19X65sec with a SCT - M42 is a stellar nursery where new stars are being formed. 700 stars in various stages of formation have been detected within the core of the nebula.

Will Sheila Jackson Lee be calling for an investigation of why we bombed Mars without giving diplomacy a chance to work?

Here is a great video for those that want to know more about this fantastic mission, complete with how the mission has unfolded, with simulated double impact video.

It’s only about a 4 minute video and well worth watching.

I have all the equipment to see it from home, I am an astronomer.

But I’m out of town on biz.

Sucks, but I’ll take the LRO and Hubble views!
