Astrosat - find maximum delay of light arrival from moon

In summary, the ASTROSTAT satellite with a diameter of 2 meters is scheduled to be launched into space in 2007 and will orbit the Earth at an altitude of 800 Km. The maximum delay in light arrival from the Moon at the satellite will depend on whether the satellite and the Moon orbit in the same plane and if the eclipse period should be taken into account. Further calculations, such as finding the satellite's velocity, may be necessary to determine the maximum delay.

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?
 

FAQ: Astrosat - find maximum delay of light arrival from moon

1. What is Astrosat and why is it important?

Astrosat is an Indian space observatory designed to study celestial objects in different wavelengths of light. It is important because it allows scientists to gather data and insights from various sources in space, helping us better understand the universe.

2. How does Astrosat measure the delay of light arrival from the moon?

Astrosat uses specialized instruments called Spaceborne X-ray Telescopes (SXTs) to measure the time taken by X-rays to reach the satellite from the moon. By analyzing the data collected from these telescopes, scientists can calculate the maximum delay of light arrival from the moon.

3. Why is it important to find the maximum delay of light arrival from the moon?

Knowing the maximum delay of light arrival from the moon can help scientists understand the physical processes that occur on the lunar surface and how they affect the propagation of light. This information can also be used to improve communication and navigation systems for future space missions to the moon.

4. What factors can affect the delay of light arrival from the moon?

The delay of light arrival from the moon can be affected by various factors such as the distance between the moon and the satellite, the composition and density of the moon's atmosphere, and the angle at which the light is being observed. Other factors such as solar activity and gravitational forces can also play a role.

5. How can the data from Astrosat's measurement be useful for other scientific studies?

The data collected by Astrosat can be used for various scientific studies such as understanding the evolution of the moon, studying the lunar surface and its geological features, and detecting any changes or anomalies in the moon's environment. Additionally, the data can also be compared with measurements from other sources to validate and improve our understanding of the moon and its properties.
