Thanks Davenn. That answers everything.

Experts - Why they don't increase altitude of ISS to overcome slight atmospheric drag it faces. Due to this, they need to make altitude corrections frequently to ISS. I want to know, why they can not put ISS in higher orbit where there is almost nil atmospheric drag (or may be altitude...

Suppose I am on ISS and Earth is exactly below (at the right angle to the ISS's line of path). Now if I throw one ball below towards Earth from window at exactly 90 degrees to the line of path of ISS and one ball upwards at right angle to the line of path of ISS. **Assume normal human strength...

Welcome Vinayak !

Got it. Thanks all !

Thanks Simon. I intend to keep Rosetta stationery relative to comet. Hence I would like to match the orbital and rotational speed.

Excellent ...thank you Bandersnatch. So does it mean if by some mechanism ISS "tugs" Earth through a cable long enough, will Earth move out of orbit ?? This is silly question I know... but so I am :-)

Phinds, Yes I know about inertia. It means unless you apply force, the object will continue to move or rest in the same place. I want to know how much force will be required if my spacecraft becomes stationery relative to the asteroid by matching it's speed, rotation etc.

Hello All, Consider below scenario. Suppose there is a small asteroid in space rotating around itself. I reach to that asteroid in my spacecraft and match spacecraft 's orbital speed with the rotation speed of the asteroid. I eject my fancy carbon fiber net from my spacecraft which is...

Hi All, I know that Rosetta was orbiting around 67P/Churyumov–Gerasimenko. This asteroid has extremely low gravitational force acting on Rosetta. I believe that if the celestial body is heavy (mass), then there would be greater gravitational pull on the satellite and the orbital speed of it's...

Thank you !

Excellent Janus ... thanks I can imagine a bit what you are saying ! Yes, the Earth's orbit around sun is too complex and there are around 5-6 different types of velocities to consider. For example, Earth orbit is not circular, sun is also moving in certain direction itself, and then whole...

Dear All, New member on this forum and very excited. I am a Physics graduate with deep interest in space science. I hope I will be able to contribute to this beautiful forum by asking questions (stupid many times !) or answer something which I know for sure. Looking forward to have lasting...

Dear All, Is it possible to watch Earth orbiting the sun in space like we watch a car coming towards us on a highway ? I mean, I would like to see it coming towards my spaceship at the rate of say 50 km/hr. Now some questions - 1. What should be my location and speed of my spacecraft...
