Is is possible to launch a satellite to a strange orbit?
For instance is is possible to launch a space vehicle from Baikonur (47 degrees north) and place the satellite into orbit with inclination of 28 degrees . But only during the boost phase.- Alex Nesh

Is is possible to launch a satellite to a strange orbit?
Is it possible to launch the satellite into orbit with inclination less than of latitude of the launch site? Can you please explain to me using some formulas.- Alex Nesh

Graduate Could a collision cause Venus to rotate prograde?
I got in an argument and I was defending one of the theories about Venus' slow prograde rotation. I'm defending the theory which states that atmospheric friction, over a period of billions of years slowed initially fast rotation of Venus and made it go prograde. My opponent says that it...- Alex Nesh

Graduate How long would we live without the sun
Sorry, I was talking about the first red giant phase ( when it depletes hydrogen). With very strong solar winds it will lose quater of its mass in the course of a few million years, that in turn will result in lower central gravity in the solar system, and planets in response will move outwards...- Alex Nesh

Graduate How long would we live without the sun
For what I understand, at the last stage of its cycle the the sun will lose almost a quater of its mass as the result of outer layer expansion, that would (in my opinion) change solar system orbits of the planets, do you think that would make sence?- Alex Nesh

do you think the Earth would change its orbit as the sun becomes red giant, or would it be engulfed by the "surface" of the sun altogether?- Alex Nesh

... and ambient temperature of space in solar system is 2.4K, so that's the temperature the Earth would eventually reach at infinity, correct?- Alex Nesh

Graduate How long would we live without the sun
The temperature of unlit side of the moon is not low enough to liquify any of the air components, correct? Now, the lowest point (of rapidly desending temperature) will reach in a matter of a few days? The presence of atmosphere on the outer planets or satellites (like Titan) makes litte...- Alex Nesh

Graduate How long would we live without the sun
Would heat capacity of air and water play a major role in the heat "giveaway" since the Earth crust acts as a good insulator from its interior and covered substantially by water. Also, would the temperature on "dark" Earth resemble the temperature of unlit side of the moon? Do "airless" planets...- Alex Nesh

How much heat does Earth radiate into space (as black body). Would you please specify a formula for that.. Thank you.- Alex Nesh

I saw another notion that as the sun expands in size it would "push" the Earth beyond its present orbit... Now, back to my freezing question: What would be immediate effects of absense of sunlight and how long do you think it would be before our world would become a perfect cryogenics lab?- Alex Nesh

Graduate How long would we live without the sun
I was trying to come up with a solution to the timeline when hypothetically speaking the sun would stop shining ( or emitting radiation). Now, gravitational issues aside (the sun as a body still there), how long would it take for median temperature to drop beyond freezing point around the globe...- Alex Nesh
