Why is the ISS at a 51.6 degree orbital inclination?

In summary, a big chunk of space hardware, believed to be the remains of the second stage of the Long March 11 rocket launched by China, has fallen harmlessly in the north of Myanmar. The orbit was sun-synchronous and had an inclination of 98 degrees, passing over Myanmar on its way up. This raises questions about the safety measures taken during launches, as well as the correlation between orbital inclinations and potential conflicts with neighboring countries.

From what it looks like, I'd say it's the remains of the second stage of the Long March 11 which China launched that day. The orbit was sun-synchronous and was probably around 98 degrees inclination, so it would be heading about 8 degrees West of South from the Jiuquan Launch Center, which would take it over Myanmar on the way up. Seems a bit careless to launch in a direction which will drop hardware on an inhabited area, especially in another country.

Edit: After a bit of Googling, found more pictures and a somewhat weirdly translated report: http://www.bestchinanews.com/Military/4038.html

This sounds as if I should check this website here, that has been linked by a user some weeks ago, far more often.

Interesting correlation here, China figures into it.

"Now, as to why specifically 51.6 degrees. This seems a little weird, at first, because we know the Russians launch from Baikonur. But if we look up Baikonur on a map, we see its latititude is at about 46 degrees.

But, sometimes rockets fail on ascent. And having a neighbor that could see rocket bodies falling on it as an attack, it becomes prudent to try to avoid flying over that neighbor on ascent."
 

1. What is space debris?

Space debris refers to any human-made object in Earth's orbit that no longer serves a useful purpose. This can include old satellites, rocket parts, and other fragments of space equipment.

2. How common are space debris falls?

Space debris falls are relatively rare. On average, one large piece of space debris falls back to Earth every year. However, smaller pieces of debris can fall more frequently.

3. How does space debris fall to Earth?

Space debris falls to Earth when it enters Earth's atmosphere and is pulled towards the surface by gravity. As it falls, it burns up due to the friction of the atmosphere.

4. Can space debris falls be dangerous?

While space debris falls are rare, they can pose a danger to people and property on the ground. Larger pieces of debris can survive the heat of reentry and potentially cause damage upon impact.

5. What happens to space debris after it falls to Earth?

After space debris falls to Earth, the debris that survives reentry will scatter across the ground. Depending on the size and location of the fall, debris may be spread out over a large area, making it difficult to track and collect.
