Launch of the Sspace Shuttle and its effect on the Earth's motion

In summary, the conversation discusses the theoretical effects on kinetic energy, momentum, and velocity of the Earth when a space shuttle of mass m is shot into space, causing a decrease in the Earth's mass to M2 = M-m. The assumption is made that the gas pillar from the shuttle has no effect on the Earth. There is also a discussion about the terminology of "theoretical" and "real" effects, as well as the potential increase in velocity of the Earth due to the decreased mass. It is also mentioned that the momentum may remain constant due to the assumption of no recoil effects from the gas pillar. The conversation ends with a hypothetical scenario involving two bricks in orbit around the Earth and the removal of one brick.

Assume we shoot a space shuttle of mass m to space. We know it affects the Earth's mass M by decreasing it to M2 = M-m. Assume that the gas pillar that the space shuttle shoots has no effects on earth, what would be the theoretical effects on kinetic energy, momentum and velocity of the Earth by the decreased mass, although miniscule obviously?

Can you do any of these calculations yourself? And why do you say "theoretical"? Do you not believe that the effects would be real?

I would assume that the momentum remained constant cause of the assumption of gas pillar having no effect, i.e no recoil effects? Then velocity would be increased with the decreased mass? Correct? Incorrect?

And by theoretical i mean real... just theoretical relating to the effects being miniscule.

What are the components of momentum? Do they stay the same?

Then velocity would be increased with the decreased mass? Correct? Incorrect?
Would it matter in what direction the rocket was launched?

OK, but that's poor terminology. If you mean minuscule, SAY minuscule.

Two bricks tied together are in a circular orbit around the earth. You don a space suit, carefully untie the string and remove one of the bricks without disturbing the other. Does the undisturbed brick double its orbital velocity as a result?
 

1. How does the launch of the Space Shuttle affect the Earth's rotation?

The launch of the Space Shuttle does not have a significant effect on the Earth's rotation. The Space Shuttle weighs only a few hundred tons, while the Earth weighs around 6 sextillion tons. Therefore, the launch of the Space Shuttle does not have enough mass to significantly alter the Earth's rotation.

2. Does the launch of the Space Shuttle change the Earth's orbit?

No, the launch of the Space Shuttle does not change the Earth's orbit. The Space Shuttle is launched within the Earth's atmosphere, which is a very small fraction of the Earth's overall size. The Earth's orbit is primarily affected by larger bodies such as the Moon and other planets.

3. Can the Space Shuttle's launch cause earthquakes or other natural disasters?

No, the launch of the Space Shuttle does not have enough energy to cause earthquakes or other natural disasters. The energy released during a Space Shuttle launch is equivalent to a small earthquake, but it is dispersed over a larger area and does not have a concentrated impact on the Earth's surface.

4. Is there any environmental impact from the launch of the Space Shuttle?

The launch of the Space Shuttle does have some environmental impact, primarily from the release of carbon dioxide and other gases during the launch. However, these emissions are relatively small compared to other human activities and do not have a significant effect on the Earth's overall climate or environment.

5. Can the launch of the Space Shuttle affect the Earth's magnetic field?

No, the launch of the Space Shuttle does not affect the Earth's magnetic field. The Earth's magnetic field is primarily influenced by the Earth's core and does not have any significant interaction with the Space Shuttle during launch.
