Haven't heard about the NASA design yet, but JAXA's 2010 IKAROS used "Eighty blocks of LCD panels are embedded in the sail, whose reflectance can be adjusted for attitude contro ".

Thanks for reminding me of a great film I saw in theatres long ago... I was at a con once and heard Barry (spouse and I both liked 'Enemy') and bought his Workshop book ... good to see he's still kicking ...

and thanks too for hooking me up with Feral Historian's stuff (like his style) which I might never have found otherwise..

Now for the next test: 3 identical new styluses responses are profiled. Now 3 identical TTs, play Marcus Family vs. Metallica vs Lou Reed's Metal Machine Music.

After 100 hours compare stylus profiles to originals. Repeat after 1000 hours. Also visit your shrink before and after for a comparitive sanity test.

We haven’t pinned down the masses of any individual neutrino, and we don’t even know which ones are heavier than the others. When it comes to our ability to collect raw data, neutrinos present a triple threat: they’re incredibly lightweight (even the electron weighs over 5 million times more than all the neutrinos combined), they shift their identity as they travel (and their rate of flavor oscillation changes as they travel through different substances, so there’s no one-size-fits-all solution), and they barely interact with anything in the first place...

GOSH I'd like to see that be 2 times longer, and have some price-ranges.

The 2003 event produced the biggest-ever solar flare ever measured, an X45. That year, several BIG transformers exploded in South Africa. This event's biggest so is 8.7. A lot depends on where it's aimed at ... but anyway , no, we are not prepared.

Powerful message. "Brought to you by DHHS, National Cigarette Foundation, Department of Education, Cigs4Kidz, and Viewers Like You."

Don't remember any PSA's like that back from when they were doing atmospheric testing of atom bombs down in Nevada for weeks on end. But they weren't planning on smoking them all the way.

Different strokes! esp. depending on which orbit you're in.
