i did a quick google on that and nothing came up can you give more info?Nicholas said:...and comet Luling is on the way!

the volume of space debris in Low Earth orbit is so high that objects in orbit are frequently struck by debris, creating even more debris and a greater risk of further impacts.

This thought was in my mind when I posted the photo. Even if this photo is only an impression, there must be a fair number of satellites orbiting Earth now, with more being sent up each week, or so it seems. Collisions under these conditions seem inevitable sooner or later, osit. That isn't to imply that the surmisings of other forumites are wrong, though.
The only surprise here is that the recent (and first) Iranian satellite wasn't involved. Fwiw.

WASHINGTON - The crew of the international space station had a close call with space junk Thursday. The three astronauts briefly took refuge inside a Russian escape capsule before returning inside the space station. Officials moved them into the capsule because they were worried that the orbiting outpost might get hit with a small piece of passing space debris.
"We've cleared," station commander Mike Fincke radioed to Mission Control in Houston as he prepared to go back inside.
The debris measured about a third of an inch, part of a motor that helped boost a satellite into the proper orbit, said NASA spokesman Kyle Herring. Tiny pieces of debris could cause a fatal loss of air pressure in the station.
NASA usually tries to move the space station out of the way of space junk, but they got this warning Wednesday night when it was too late to move the station, Herring said.
Instead, NASA sent the crew to the Soyuz capsule, a move that has been done in the past, Herring said. A Soyuz capsule is parked at the space station to serve as a lifeboat if needed for the station's residents.
The piece of debris was expected to come within the 2.8 mile box of space around the station that makes up NASA's danger zone, Herring said.
"We were looking out the Soyuz window," Fincke radioed to Houston. "We didn't see anything of course. We were wondering how close we were."
Because the U.S. Strategic Command, which monitors space debris, could not get a good enough look at the debris, NASA may never know exactly how close it came, said NASA spokesman Josh Byerly. It was traveling 5.5 miles per second -- about 20,000 mph, according to Byerly.
The debris is likely a tiny weight followed by a 39-inch string or strand that was used to stabilize a global positioning satellite placed in orbit in May 1993, said Harvard astrophysicist Jonathan McDowell, who tracks all objects in orbit.
One of the reasons NASA got such late warning on the debris is that it is an unusual orbit that keeps dipping into the atmosphere and changing, McDowell said. The GPS satellite went out of daily use in January, he said.
Fincke is one of two Americans living aboard the space station; the third resident is Russian.

Perseids perhaps, anyone? There wasn't any satellite collisions back then?NASA has moved the space station out of the way of debris eight times in the past, most recently in August, according to NASA records.
Two US Navy vessels - a submarine and an amphibious ship - collided early on Friday in the Strait of Hormuz between Iran and the Arabian peninsula, the US Navy's 5th Fleet reported.
The military said in a statement the USS Hartford, a submarine, and the USS New Orleans, an amphibious ship, collided around 1 am local time.
According to the Bahrain-based 5th Fleet, 15 sailors aboard the Hartford were slightly injured but able to return to duty. No injuries were reported aboard the New Orleans.
SOA said:It reminds me of the crane collapses/crashes all last year. Do we have another message from the universe starting to come in? This is more and more a "smashing" year isn't it?
SAO said:I just wanted to document this one here, it seems like we're on a roll this year with the collision stuff. We have 2 satellites, 2 submarines, and now a ship and a submarine:

And so far I think we had about 3 sizeable meteors come very close to earth this year (closer than the moon). I dunno if there's any kind of symbolic (or not symbolic, like if the collisions are supposed to distract from meteors or something) relationship here..

US space shuttle moves to avoid junk
The astronauts aboard the International Space Station and space shuttle Discovery have been instructed to move out of the way of a four-inch piece of space junk, the US National Aeronautics and Space Administration (NASA) said Sunday.
According to the space agency, Discovery's pilots fired their ship's thrusters to avoid the junk, which is likely to uncomfortably approach the station Monday.
NASA said keeping the spacecraft in this position for about three hours is enough to get the space station and Discovery out of the junk.
It's the third time this month that the space station was confronting a space junk. On March 12, astronauts aboard the space station took emergent refuge in Russia's Soyuz capsule in case of a collision with a flying debris cloud. And last week, the space station almost had to dodge yet another piece of junk.
On Saturday, astronauts Steven Swanson and Joseph Acaba finished the second of three planned spacewalks to make preparation for NASA's future space shuttle mission and the debut flight of a Japanese cargo ship. During the spacewalk, they loosened connections on batteries on the external Port 6 truss, ready for their replacement on a later mission in June.
The two also installed a GPS antenna to the outside of the station's Japanese module. The GPS device will help guide the Japanese HTV robotic spacecraft, a cargo transfer vehicle to be put into operation later this year.
Other tasks include outfitting the station's truss with attachments for experiments and cargo platforms and using an infrared camera to photograph radiator panels so engineers can assess how they have withstood the harsh space environment.
However, they accidentally inserted a pin upside down and jammed an equipment storage platform at the International Space Station.
One more spacewalk is planned next Monday during Discovery's mission.
Discovery was launched into space last Sunday night. During its stay with the station, three spacewalks will be conducted by astronauts. If all goes well, it is scheduled to undock from the station March 25, towards a planned March 27 landing at the Kennedy Space Center in Florida.
