A new way for satellites and rovers to study a planet. Today, Earth. Tomorrow, the moon, Mars and beyond.

"EO-1 is a new breed of satellite that can think for itself. ‘We programmed it to notice things that change (like the plume of a volcano) and take appropriate action,’ Chien explains. EO-1 can re-organize its own priorities to study volcanic eruptions, flash-floods, forest fires, disintegrating sea-ice—in short, anything unexpected."

Scrunching this up took a while, but it still conveys the essential detail. Increasing small amounts  of the incandescent planet are dark at night, except for the oceans, of course. /NASA 

Today’s pretty picture — sor’ a thing.

Congestion near the center of our Milky Way Galaxy. More than 180,000 stars. And you thought your neighborhood was crowded. Sweeps field (upper left corner) refers to Hubble Space Telescope’s sweep of the area hunting for possible solar systems–looking for brief, periodic changes in brightness when a Jupiter-size planet passes in front of its parent star–candidates for which are within the green circles. /NASA

First word from the moon: Houston

While Times Online claims Neil Armstrong’s planned utterance ("One small step…" etc.) was ungrammatical–and sci fi writer Arthur C. Clarke (writing in 1986) agreed–until an Australian computer expert recently uncovered the missing article. Well, every Texas schoolboy knows the REALLY important matter was the First Word from the lunar surface, not those planned-in-advance words.

That first word? "Houston," as in Armstrong reporting the landing by saying "Houston, Tranquillity base here…" etc. I used to have a colorful poster of an orbiting city made up by the Houston chamber of commerce crowing about it. As a paid scribe, I even once examined the official transcript to confirm it.

Comes Wikipedia claiming the first words were those of Buzz Aldrin: "The first words spoken from the surface were Aldrin’s, who reported ‘Contact Light’ as the Eagle’s landing probe touched the moon."

Harrumph. This is why, as we so often hear, Wikipedia’s encyclopedic veracity is questionable at best.

It’s been called the finest achievement of the Space Age, taking pictures of the Earth in context. This is one of the oldest and best-known, the Apollo 17 look-back at the African continent, which some scientists consider the cradle of humanity/NASA
