what are the characteristics of space at 650-800km height ie
what would be pressure, temperature, albedo factor , solar constant, Earth IR, etc

Here's one link from http://www.fas.org/spp/military/docops/army/ref_text/chap5im.htm. The Air Force's Air University also has a decent text on space environment, but that's probably not publicly available. They do have a Space Primer that discusses space environment and it's impact on spacecraft .

The characteristics of space at 650-800km height can vary, but here are some general estimates:

- Pressure: At this height, the pressure is considered to be extremely low, almost near vacuum levels. It is estimated to be around 10^-9 to 10^-11 Pa.

- Temperature: The temperature at this height can also vary, but on average, it is around -100 to -150 degrees Celsius. However, this can fluctuate depending on solar activity and other factors.

- Albedo factor: The albedo factor refers to the reflectivity of a surface. In this case, the albedo factor of space at this height would be close to zero, as there is no atmosphere to reflect or scatter light.

- Solar constant: The solar constant is a measure of the amount of solar radiation that reaches a specific area in space. At 650-800km height, the solar constant is estimated to be around 1361 W/m^2.

- Earth IR: Earth IR (infrared) refers to the amount of infrared radiation that is emitted by the Earth. At this height, the Earth IR would be relatively low, as the atmosphere is the main source of infrared radiation.

Overall, space at 650-800km height is a harsh and inhospitable environment, with extremely low pressure, low temperatures, and minimal reflective properties. However, it is also a fascinating and important area for scientific research and space exploration.
