Earth at Twilight

Explanation: No sudden, sharp boundary marks the passage of day into night in this gorgeous view of ocean and clouds over our fair planet Earth. Instead, the shadow line or terminator is diffuse and shows the gradual transition to darkness we experience as twilight. With the Sun illuminating the scene from the right, the cloud tops reflect gently reddened sunlight filtered through the dusty troposphere, the lowest layer of the planet's nurturing atmosphere. A clear high altitude layer, visible along the dayside's upper edge, scatters blue sunlight and fades into the blackness of space. This picture actually is a single digital photograph taken in June of 2001 from the International Space Station orbiting at an altitude of 211 nautical miles.

Vacation Announcement

I will be on vacation from June 2nd through June 9th.
If anyone would like to volunteer to post APOD during that time, please FReepmail me.
Otherwise the APOD will not be posted as I will be visiting relatives in California.

I couldn't post APOD this AM because of computer problems (network).

The above image is REALLY what you would see from orbit. Remember that digital image that was making the rounds recently?

That's the one. You can read about it in the 3-24-03 APOD and compare it to today's photo.

I was so inspired by that pic that I was looking for a verse from Genesis to post here. I found this instead. So much for the recondite post. :)

On July 20, 1969, as commander of the Apollo 11 lunar module, Neil Armstrong was the first person to set foot on the moon. His first words after stepping on the moon, "That's one small step for man, one giant leap for mankind," were televised to earth and heard by millions. But just before he re-entered the lunar module, he made the enigmatic remark,"Good luck, Mr. Gorsky." Many people at NASA thought it was a casual remark concerning some rival Soviet cosmonaut. However, upon checking, there was no Gorsky in either the Russian or American space programs. Over the years, many people questioned Armstrong as to what the "Good luck, Mr. Gorsky" statement meant, but Armstrong always just smiled. On July 5, 1995, in Tampa Bay, Florida, while answering questions following a speech, a reporter brought up the 26-year old question to Armstrong. This time he finally responded. Mr. Gorsky had died, so Neil Armstrong felt he could answer the question. In 1938, when he was a kid in a small Midwest town, he was playing baseball with a friend in the backyard. His friend hit the ball, which landed in his neighbor's yard by the bedroom windows. His neighbors were Mr. and Mrs.Gorsky. As he leaned down to pick up the ball, young Armstrong heard Mrs.Gorsky shouting at Mr. Gorsky, "Sex! You want sex?! You'll get sex when the kid next door walks on the moon!"
