There is an opinion that Ukraine was a ticking time bomb since Ukrainian "independence" because of the black sea fleet, sevastopol base has been crucial to russian armed forces doctrine. Something had to happen there before 2017 anyhow. http://news.kievukraine.info/2...

it is yet unknown whether it is an engine problem or software glitch. if it's the latter, they will attempt to upload an updated version and send it off. main engine hasn't fired, so they still have fuel. however, they have only three days to find out the problem with software, batteries won't last for much longer.

Submission + - Hubble accuracy surpassed by earthbound telescope (arizona.edu)

"A special sensor detects atmospheric distortions in real time and controls the mirror to adjust its position to compensate, effectively canceling out the blurring. The mirror can make adjustments every one-thousandth of a second, with accuracy to better than ten nanometers (a nanometer is one millionth the size of a millimeter)."

Now, that's what I call real-time. This nifty trick multiplied Strehl ratio (optical quality) of LBT by about 80 times to unprecedented Rayleigh limit. Hope we'll see more space around us in higher resolution on Google Sky.

isn't it obvious, that once something has happened it cannot be erased from history of this light cone? the only thing you could possibly do about events in your past is to provide an alternative version preferably as soon as this happened. i have plenty of record online under my real name, of course there are some things that are embarassing to me ages ago, but plenty of time has went past :)
