OMG!!!

People with no understanding of orbital mechanics, unite!!!

Folks....the ISS has no engines. It cannot alter its orbital trajectory. Those who think it can are sorely misinformed.

Further research into how satellites move, on orbit, and the energy required to alter their orbits is warranted. Just google...look for 'plane change' in the keywords. Because, an object in orbit describes a 'plane' of motion...and to alter that plane, into a new trajectory, reuires a LOT of energy. We don't (AFAIK) have 'Star Trek' technology yet.....

Considering that the ISS takes 90 minutes to orbit the planet, the chances of it passing over NY on the day of the attacks are fairly good.

Plus, they mentioned seeing smoke rise from the rubble, meaning they weren't overhead as the attacks occured as you seem to be implying. But passed over later in the day.

I'm highly sceptical of this story myself, but there are engines on the space station, according to what I have read.

I've never heard of it moving before.

www.howstuffworks.com...



When completed, the ISS will be able to house up to seven astronauts. It will have the following major components:

•Control Module (Zarya) or Functional Cargo Block - contains propulsion (two rocket engines), command and control systems
•Nodes (three) - connect major portions of the ISS
•Service Module (Zvezda) - contains living quarters and life support for early parts of the ISS, docking ports for Progress resupply ships and rocket engines for attitude control and re-boost
•Scientific Laboratories (six) - contain scientific equipment and a robotic arm to move payload on an outside platform
•Laboratory Module - shirt-sleeve environment facility for research on microgravity, life sciences, Earth sciences and space sciences
•Truss - long, tower-like spine for attaching modules, payloads and systems equipment
•Mobile Servicing System - robotic system that will move along the truss; equipped with remote arm for assembly and maintenance activities
•Transfer Vehicles - a Soyuz capsule and a Crew Return Vehicle (X-38) for emergency evacuation
•Electrical Power System - solar panels and equipment for generating, storing, managing and distributing electrical power


If the story is true, it certainly would add to the air of stage management that already hangs over 9/11.

here is the video. looks like 911 video is a after thought.
dont know we need to take a closer look.

I noted no issues with the above statements. and accept them as true.

just the data from Celestia does not match what is common knowledge.

...but there are engines on the space station...


Irrelevant, and not adequate to effectively alter the orbital inclination at all.

Plus, there is insufficient propellant that would be needed in order to alter the delta-v enough...

Any engines are to provide orientation, or possibly to boost if orbit decays over time. The energy to actually alter the inclination far exceeds what is available, given current understanding of technology and physics.

It has already been pointed out that the 9:00 AM claim is wrong. It doesn't even make sense. The first plane hit at 8:46, the second at 9:03.

The orbital elements of the space station, like all satellites, change over time due to a variety of reasons. Celestia calculates the position of the ISS based on those orbital elements. Unless the orbital elements of Sept. 11, 2001 are used in the calculations Celestia will provide an incorrect position for the station. The greater the time span between the orbital elements used for the calculation and the time you are looking at, the greater the error.

Folks, this is a test. How many of you still want to carry on this thread even though you have been told the simple facts that it cannot be true, and given the fact that it comes from an unknown source?

For myself, I hope to note the user names of those that want to hang on and argue. I'll try to avoid reading anything they have to say in the future.

It only takes 90 minutes for the ISS to orbit the Earth, so even if it was over the Horn of Africa at 9:00 AM, it would be able to see NYC before 10:30 AM (and possibly again before noon, depending on it's course).

If you understood the orbit of the ISS, you would know there was plenty of time and opportunities for the ISS to see the smoke.

This theory is a non-starter.

I want to preface this by saying that I am not a space expert. I'm just using my noggin here, but I think this is correct.

Here is a diagram taken from a NASA related website. It shows orbital tracks of the International Space Station.

spaceflight.nasa.gov...

There are variations in the orbital path. (Edit: Later posters in the thread point out that the ISS doesn't go over the same parts of the earth on each orbit. Undoubtedly there is a technical jargon term for this kind of non synchronous orbit. However the most important point is that the non-synchronous orbit of the ISS can be slowed or speeded up by raising or lowering it's altitude.)

To arrange to be over a certain place on earth at a given time they would only have to raise or lower the orbit of the space station, allowing it to to come into line with a point on the earth (New York City), which they have the ability to do and have done (probably numerous times).

This suggests another way it could have been done, with advanced planning. Use the fuel and engines from an unmanned cargo vehicle from earth to raise the orbit when it docked at the station.

www.space.com...

A cargo ship docked at the International Space Station (ISS) fired its engine Wednesday, raising the space research platform into a higher orbit to prepare for the arrival of two spacecraft in upcoming months.

The unmanned Progress 17 spacecraft, a supply ship that docked at the ISS on March 2, fired its engines at 10:27 a.m. EDT (1427 GMT) to boost the space station 1.5 miles (2.4 kilometers) further from Earth into an orbit that reaches 226 miles (363 kilometers) at its highest point, NASA officials said.

The orbital boost prepared the ISS for the June docking of Progress 18, the next Russian cargo ship to deliver space station equipment and supplies, as well as the expected July arrival of the space shuttle Discovery and its STS-114 crew.
