Astrosat - find maximum delay of light arrival from moon

Click For Summary

Homework Help Overview

The discussion revolves around calculating the maximum delay of light arrival from the Moon to the Astrosat satellite, which is set to orbit Earth at an altitude of 800 km. Participants are exploring the implications of the satellite's position relative to the Moon and Earth.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants question whether the calculation can be simplified by adding the satellite's altitude to the distance from the Moon to Earth and dividing by the speed of light. They also consider the orbital planes of the satellite and the Moon, and the potential impact of lunar eclipses on light arrival.

Discussion Status

The discussion is ongoing, with participants raising various considerations regarding the orbital dynamics and potential eclipses. Some guidance has been offered regarding the need to account for these factors, but no consensus has been reached on the approach to take.

Contextual Notes

There is uncertainty regarding whether the eclipse period should be included in the calculations, and the specific orbital characteristics of the satellite and the Moon have not been clarified.

ASTROSTAT satellite of 2 meter diameter will be in space in 2007. If it revolves around the earthat an altitude of 800 Km, find the maximum delay in light arrival from Moon at the satellite at different locations.

Is it as simple as adding 800km to distance of moon from Earth and dividing it byspeed of light?

That depends. Do the satellite and the moon orbit in the same plane? If so, do you need to take into account the fact that for a part of the time the moon will be eclipsed by the Earth from the satellites view and light from it can't reach the satellite at all at this time?

Well, Whats the same plane?? It wasnt specified whether the eclipse period should be taken in accout. What if I try to calculate it both ways?
 
Please help me soon. If I get the velocity of this satellite, then what should I do next?
