| | World on alert for satellite debris and fragments | | 2008-02-21 07:26:00 | | Many countries all over the world is on the alert for possible harmful fall-out from the US shootdown of a failed USA-193 spy satellite. China asks US to provide more datails on satellite explosion. In the meantime FEMA has provided "Memo About Falling Satellite" that have been sent to thousands of local police, fire and emergency service agencies around the country. This 18-page guide also has helpful hints for the public. Space experts doubt that debris from the spy satellite will hit anywhere near land. Moreover the most likely consequence would be a meteor shower of small bits of debris."The debris cloud would cross the dark Canadian coast north of Vancouver fifteen minutes after the shoot down," said Jim Oberg, space analyst. "I expect that some of the most energetically expelled fragments will be hitting the atmosphere all along this track. It could be a meteor shower to remember."

| Satellite Moved To Avoid Chinese ASAT Debris | | 2007-07-07 13:28:00 | | NASA's Terra Satellite Moved to Avoid Chinese ASAT DebrisWASHINGTON - Flight controllers at NASA's Goddard Space Flight Center, Greenbelt, Md., had to maneuver the Terra environmental spacecraft in late June to avoid orbital debris created by the Jan. 11 test of a Chinese anti-satellite (A-Sat) weapon. As written previously, China's ASAT test was a dangerous act of aggression. The fact that NASA had to reposition a satellite only exemplifies the stupidity of space warfare around Earth.... | | By: Thoughts on the World | | |
| | Debris, Garbage and Rubbish | | 2007-04-16 21:53:00 | | This week's posting is not about cute, cuddly or other interesting bits of wildlife. This is the natural history of waste. While filming in waters off the Philippine island of Cebu, the crew encountered a typhoon, a common enough experience for that part of the world, and in itself not very remarkable perhaps. Though it did create some interesting rain drops on sea water effects, as you can see from this still image taken from the film.No, the point of interest in this week's posting lies with the amount of debris which the winds and currents churned up, to produce a long slick of flotsam and jetsam.What astonishes me is the sheer amount of true debris, garbage, and rubbish that you can see, hidden amongst the uprooted and broken bits of seaweed. Most obvious is plastic, plus other unidentifable things, the origins of which I don't really want to guess. Of course I know that the oceans are polluted, and have been for decades, but it's not until you have close personal experience that the size, scale and nature of the problem is realised. I was not on the trip of course, but the crew have talked about it in the tea-room since.Greenpeace have an illuminating (if that's the right word) website, describing what is known as the 'trash vortex', which lies in the eatern part of the Pacific Ocean where winds are light and the currents bring together huge amounts of rubbish.The threats to wildlife from the unsightly mass of mess are well known. Entanglement in plastic by turtles, or marine mammals can lead to drowning. And ingestion of larger items of debris by seabirds who mistake it for prey, can lead to starvation.NHNZ Images has amongst its holdings things like pollution that unfortunately show the world in its true light.
