Many folks would like to see us back on the Moon and developing its resources.

Exploding Lunar Eclipse

There is a Lunar Eclipse tonight/morning.
One of those times that the Sun, Earth, and Moon form a straight
line letting Earth's shadow fall on the Moon.

It also happens to be at a time when the Moon may be pelted by a bunch
of baseball size objects. These objects are coming from the Sun sided
and are normally hard to see when impacting a lit Moon but in the shadow
of the Earth the flash of light given off by the impacts may be captured
with a telescope and video camera.

One would like to get some data on how many objects may be hitting the
Moon especially if you want to set up a base camp and stay around for

How do you go about protecting yourself when the sky is falling?
Here on Earth we have an atmosphere that does a nice job of burning them up.
Makes for falling star parties.

On the Moon one may not like to have your party disrupted by the
equivalent of 100 kg of TNT exploding next to you.

Have fun looking ulp.

AS A sky show, it has kept Australian star-gazers waiting for seven years.

A spectacular total lunar eclipse will be visible across the country
tomorrow at full moon, when the sun, Earth and moon are in perfect

The Earth casts a shadow across the moon and blocks out the sunlight,
causing the moon to become dark, almost disappearing.

Although it is a total eclipse, the moon will not completely black out.
Some sunlight will reach it, bent by the Earth's atmosphere.

NASA Science News for August 27, 2007

On Tuesday morning, Aug. 28th, a team of astronomers and engineers at
the Marshall Space Flight Center will attempt something never done
before--to observe meteoroids hitting the Moon and exploding during a
lunar eclipse. This will allow them to explore an elusive and mysterious
population of "Helion" meteoroids coming from the direction of the sun.

Dreamy Lunar Eclipse

*August 3, 2007:* Close your eyes, breathe deeply, let your mind wander
to a distant seashore: It's late in the day, and the western sun is
sinking into the glittering waves. At your feet, damp sand reflects the
twilight, while overhead, the deep blue sky fades into a cloudy mélange
of sunset copper and gold, so vivid it almost takes your breath away.

A breeze touches the back of your neck, and you turn to see a pale full
Moon rising into the night. Hmmm. The Moon could use a dash more color.
You reach out, grab a handful of sunset, and drape the Moon with
phantasmic light. Much better.

Too bad it's only a dream...

Early Tuesday morning, August 28th, the dream will come true. There's
going to be a colorful lunar eclipse visible from five continents
including most of North America: map.

The event begins 54 minutes past midnight PDT (0754 UT) on August 28th
when the Moon enters Earth's shadow. At first, there's little change.
The outskirts of Earth's shadow are as pale as the Moon itself; an
onlooker might not even realize anything is happening. But as the Moon
penetrates deeper, a startling metamorphosis occurs. Around 2:52 am PDT
(0952 UT), the color of the Moon changes from moondust-gray to
sunset-red. This is totality, and it lasts for 90 minutes.

Total Lunar Eclipse: August 28, 2007

during the Total Lunar Eclipse of Aug. 28, 2007.
(Pacific Daylight Time)


A total eclipse of the Moon occurs during the early morning of Tuesday,
August 28, 2007. The event is widely visible from the United States and
Canada as well as South America, the Pacific Ocean, western Asia and
Australia. During a total lunar eclipse, the Moon's disk can take on a
dramatically colorful appearance from bright orange to blood red to dark
brown and (rarely) very dark gray.

An eclipse of the Moon can only take place at Full Moon, and only if the
Moon passes through some portion of Earth's shadow. The shadow is
actually composed of two cone-shaped parts, one nested inside the other.
The outer shadow or /penumbra/ is a zone where Earth blocks some (but
not all) of the Sun's rays. In contrast, the inner shadow or /umbra/ is
a region where Earth blocks all direct sunlight from reaching the Moon.

If only part of the Moon passes through the umbra, a partial eclipse is
seen. However, if the entire Moon passes through the umbral shadow, then
a total eclipse of the Moon occurs. For more information on how, what,
why, where and when of lunar eclipses, see the special web page lunar
eclipses for beginners.


Lunar Eclipse Diagrams

The following diagrams show the Moon's path through Earth's shadows
(higher resolution versions of the above figure). The times of major
stages of the eclipse are given for a number of time zones in North
America. Please choose the diagram for your own time zone. Each diagram
is a GIF file with a size of about 100k.

Daylight Saving Time
<> is in
effect for most of the United States and Canada during the eclipse.
However, *Arizona* remains on Mountain Standard Time year-round and does
not use Daylight Saving Time. Eclipse times for Arizona are the same as
those for Pacific Daylight Time (The Navajo Nation in northeastern
Arizona is currently on Mountain Daylight Time).

Some people may be puzzled that the Moon's motion is from west to east
(right to left) in these diagrams, instead of its daily east to west
(left to right) motion in the sky. However, the Moon actually moves WEST
to EAST (right to left in the Northern Hemisphere) with respect to the
Earth's shadow and the stars.
