No. To remain in orbit it needs to have a certain speed, and that speed will only match the surface speed of the earth on a certain height. To go lower it'd have to go slower, and then it'd fall.
Yes, a satellite in a low tilt at a low altitude will cover more of the Earth's surface due to its proximity and angle of view compared to a satellite in a high tilt at the same altitude. The lower tilt allows for a larger field of view, capturing more of the Earth's surface in a single orbit.
lower
At 5km up the Satellite would still be in the earths atmosphere and would also be subject to gravity. Put simply it would just fall back down. Space starts at about 100km up or 62 miles. The moon also has 1/6ths of Earths gravity and at 5km up there would be little if any pull from the moon.
Air pressure decreases with altitude due to the lower weight of the air column above, leading to lower oxygen levels and potential altitude sickness. Temperature also decreases with altitude as the atmosphere becomes thinner and less able to retain heat.
high temperatures
Yes, a satellite in a low tilt at a low altitude will cover more of the Earth's surface due to its proximity and angle of view compared to a satellite in a high tilt at the same altitude. The lower tilt allows for a larger field of view, capturing more of the Earth's surface in a single orbit.
Yes, satellites at different heights can have equal velocities if they are in circular orbits with the same period. In this case, the satellite at a higher altitude will have a slower velocity than the satellite at a lower altitude, but their velocities will be equal at any given point in their orbits.
the higher you are the more the density decreases
The higher the altitude the lower the temperature.
The higher the altitude the colder the climate, the warmer the climate the lower the altitude.
lower
makes 40% oxygen than lower altitude
In general, the higher the altitude, the lower the pressure, and the lower the pressure the lower the boiling point.
The greater the altitude, the lower the air pressure.

The time it takes to put together a satellite varies on the size and structure of the satellite. A simple satellite could be put together in a couple of months, where a large science mission could take ten or more years.
Simply put, the higher the altitude, the lower the density of the air molecules.
