here's another theory for the satellite crash a few days ago
Texans report fireball in sky, sonic booms
Sonic booms and at least one fireball in the sky were reported in Texas on Sunday, less than a week after two satellites collided in space and a day after the Federal Aviation Administration asked U.S. pilots to watch for "falling space debris," authorities said
"On Saturday, the FAA told pilots through its routine notification system that "a potential hazard may occur due to re-entry of satellite debris into the earth's atmosphere." The notice did not specify a time or location"
As Joe pointed out to me, the "colliding satellites" could actually be a cover story for a known coming barrage of cometary debris.
Can't have people suddenly realizing that we may really be heading into the cosmic soup. And it ain't ducky!
Metallic meteorite likely sent fireball across Texas sky
Feb. 16, 2009, 8:47P.
Sunday’s great Texas fireball was – probably – just a meteor.
Officials with the Federal Aviation Administration and the U.S. Strategic Command said the bright lights witnessed over Texas skies were almost certainly not linked to last week’s collision between an American commercial satellite and a Russian government communications satellite
Does anyone have an idea where exactly these satellites banged into one another? Any particular region of sky, or longitude/latitude?

Hi Kenny,
Is that 122,85 East or West and do you have a source for this?
Perceval said:Are you including the subs that smashed, just a little bump though, around the same time as the satellites?

"On 13 Feb, North American Aerospace Command tracked the re-entry of a rocket body at approximately noon EST following the launch of a Russian rocket that resupplied the International Space Station. The object, 10-square meters in size, skipped off the atmosphere and re-entered off the southern coast of Africa. NORAD followed prescribed assessment procedures during the reentry and officials from the command deemed it not a threat to populated land areas in North America. NORAD does not have any further details on the reentry."

China alert on U.S.-Russian satellite collision
BEIJING, Feb. 12 (Xinhua) -- The debris left by a satellite collision above Siberia, Russia, poses a threat to China's solar synchronous satellites on the orbit, Chinese scientists told Xinhua reporters on Thursday.
Two telecommunications satellites, launched by the U.S. and Russia respectively, collided on Thursday, at 0:55:59, in an orbital area 788.57 kilometers away from the Earth, at 97.88 east longitude and 72.50 latitude, according to Zhao Changyin, a researcher with the Purple Mountain Astronomical Observatory, in Nanjing City.
A monitoring network under the Chinese Academy of Sciences (CAS) is now closely watching and searching for the debris of the damaged satellites for the safety of Chinese satellites, said Zhao. But he insisted that such in-space collisions are rare.
The American satellite, which was projected on Sept. 14, 1997, was operational until it was destroyed in the collision. The Russian satellite, launched on June 16, 1993 has ceased operation.
The American satellite, 560 kilograms in weight, was moving 780kilometers above the Earth with an obliquity of 86 degrees. The Russian satellite weighed one ton, and was orbiting 790 kilometers above the Earth with an obliquity of 74 degrees, according to the Nanjing observatory.
The debris, which is spreading in space where the collision occurred, is forming a nebulous that may disperse gradually in the future, said Du Heng, a space debris expert with the CAS who is a researcher with the Space Science and Application Research Center.
The debris cloud may affect solar synchronous satellites moving in an orbital area of 700-900 kilometers above the Earth, including China's Fengyun-1 meteorological satellite and Ziyuan-1 observatory satellite, according to the expert.
"We can calculate whether our in-use satellites will be collided or not once the data of the debris cloud is published," Du said, noting it will help China readjust the operating gesture of its satellites on the orbit.
Thursday's satellite collision occurred with a relative speed of 11.6 kilometers per second, according to Zhao. Similar collisions have occurred in the past, he said.
On July 24, 1996, a French spy satellite ran into the remains of an Ariane V16 rocket carrier. On Jan. 17, the debris of a Chinese-made Long March-4 rocket collided with the remains of an American rocket.
Satellite Collision Highlights Need For Space Traffic Control
Space traffic experts say that at least 500 pieces of potentially dangerous debris from the collision of two satellites highlight risks that should be discussed immediately.
The U.S. military monitors tens of thousands of pieces of space debris and tries to assess whether they pose a risk from collisions. The collision Tuesday of an American Iridium communications satellite and an inactive Russian Cosmos 2251 satellite has added nearly 700 more pieces at an elevation close to other satellites and the International Space Station.
NASA acknowledged that the debris could pose a slight risk to the space station, which could be moved in an attempt to avoid any debris that may move in its direction. The Secure World Foundation, however, said the collision and subsequent risks point to a need for space traffic control.
"This collision underscores in a dramatic way the importance of instituting an international civil space situational awareness (SSA) system as soon as possible," Ray Williamson, executive director of the private foundation for secure and sustainable use of space, said in a statement. "In the absence of reliable ways to clear debris from orbit, it will be increasingly important to follow all active satellites to prevent future preventable collisions."
The topic also came up at the 46th Session of the Scientific and Technical Subcommittee of the U.N. Committee on the Peaceful Uses of Outer Space in Vienna this week.
"Since space is becoming an increasingly congested environment, heightened space situational awareness as well as international cooperation between governments and industry is critical in the future," the committee said statement.
The Secure World Foundation is a fully-funded, private operating foundation dedicated to the secure and sustainable use of space for the benefit of Earth and all its peoples. The Foundation engages with academics, policy makers, scientists and advocates in the space and international affairs communities to support steps that help achieve the secure, sustainable and peaceful uses of outer space with efficient and effective global systems of governance.
Our Vision
Secure World Foundation envisions secure, sustainable and peaceful uses of outer space made possible by efficient and effective global systems of governance.
Our Mission
Secure World Foundation works with governments, industry and civil society to identify, develop and promote ideas and actions necessary for achieving the secure, sustainable and peaceful use of outer space.
Our Themes
The Foundation approaches space governance by addressing three themes: Space security, human and environmental security and planetary defense.
Space Security: Developing the foundation for the effective management of space operations. Within this theme, the Foundation focuses on civil space situational awareness, space traffic management, mitigation of orbital debris and the avoidance of a space arms race.
Human and Environmental Security: Maximizing the global cooperative use of space assets for humanity. Within this theme, the Foundation focuses on cooperative Earth observation (EO) and the global sharing of EO data.
Planetary Defense: Promoting a unified policy approach to protection of our planet. Within this theme, the Foundation focuses on global policies to govern how we detect, track and deflect near Earth objects (NEOs).
RedFox said:Interesting...I find the mention of global governance/policies unnerving. I understand the context of there website, but still. Will have to try and find out who funds them to perhaps get a hint at things. Not sure if I've gone off on a unproductive tangent or not thought?

Wikipedia said:The Kessler Syndrome is a scenario, proposed by NASA scientist Donald J. Kessler, in a 1978 publication where 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. The implication of this scenario is that the escalating amount of debris in orbit could eventually render space exploration, and even the use of satellites, unfeasible for many generations.
