Debris from satellite collision a concern
BY VLADIMIR ISACHENKOV The Associated Press
MOSCOW — The crash of two satellites has generated an estimated tens of thousands of pieces of space junk that could circle Earth and threaten other satellites for the next 10,000 years, space experts said Friday.
One expert called the collision “a catastrophic event” that he hoped would force President Barack Obama’s administration to address the long-ignored issue of debris in space.
Russian Mission Control chief Vladimir Solovyov said Tuesday’s smashup of a derelict Russian military satellite and a working U.S. Iridium commercial satellite occurred in the busiest part of near-Earth space — some 500 miles above Earth.
“[500 miles] is a very popular orbit which is used by Earth-tracking and communications satellites,” Solovyov told reporters Friday. “The clouds of debris pose a serious danger to them.”
Solovyov said debris from the collision could stay in orbit for up to 10,000 years and even tiny fragments threaten spacecraft because both travel at such a high orbiting speed.
James Oberg, an experienced aerospace engineer who worked on NASA’s space shuttle program and is now a space consultant, described the crash over northern Siberia as a “catastrophic event.”
NASA said it was the first-ever high-speed impact between two intact spacecraft — with the Iridium craft weighing 1,235 pounds and the Russian craft nearly a ton.
“At physical contact at orbital speeds, a hypersonic shock wave bursts outwards through the structures,” Oberg said in e-mailed comments. “It literally shreds the material into confetti and detonates any fuels.”
Most fragments are concentrated near the collision course, but Maj.-Gen. Alexander Yakushin, chief of staff of the Russian military’s Space Forces, said some...............http://www.dailygazette.net/De.....amp;EntityId=Ar00501 |

Mystery fireball streaks across Texas sky
Sun Feb 15, 11:31 pm ET
DALLAS – What looked like a fireball streaked across the Texas sky on Sunday morning, leading many people to call authorities to report seeing falling debris.
"We don't know what it was," said Federal Aviation Administration spokesman Roland Herwig.
The Williamson County Sheriff's Office used a helicopter to search after callers said they thought they saw a plane crashing, a spokesman said.
"We don't doubt what people saw" but authorities found nothing, said spokesman John Foster.
The U.S. Strategic Command said there was no connection to the sightings over Texas and Tuesday's collision of satellites from the U.S. and Russia.
"There is no correlation between the debris from that collision and those reports of re-entry," said Maj. Regina Winchester, with STRATCOM.
The FAA notified pilots on Saturday to be aware of possible space debris after a collision Tuesday between U.S. and Russian communication satellites. The chief of Russia's Mission Control says clouds of debris from the collision will circle Earth for thousands of years and threaten numerous satellites.

Don't worry, the County Dems already beat them to it. You know, gotta throw that big party this year for 200 years of failure. Shouldn't the bigger party be that the Metroplex has survived 10 years...and shall go on indefinitely? |
