Would it be possible to build an approximately 10x10x10 cm ion-engine to put on a cube sattelite? I am a university student, so we have a lot of tools, but not a lot of money.
What do I need to consider and how much would it cost?
Hello,
I'm currently working on satellite model for high-school compatition, and I'm not sure if there's a visual difference between a reciver & transmiter antenas (on satellites)...
Also, is it possible to satellite to recive a radio wave information from another satellite
Thank you
Hi,
I don't know if it's the right place for this question, but-
I need to create a satellite model, that after being in space, will come close to the atmosphere, and then go back up again. In its way up it need to use a pulsed thruster. (This needs to happen multiple times...)
Does a pulsed...
I am interested in theoretical (what if) possibility of our Earth having more than one moon,
I wonder if they can be arranged at the same orbital resonance as the Galilean moons 1:2:4
If yes, would such system be stable?
If yes, should our Moon be the first, second or third satellite out of the...

A scientist wants to put an 100kg experimental package in orbit around the Earth. The cost of deployment depends on the amount of extra energy it takes to get it into the required position i.e. how much more energy is used than just sending the rocket up there.

A satellite that stays over the same spot on a planet as it rotates is called a geostationary satellite. (Geostationary satellites must be positioned somewhere over the equator of the planet.) What is the average orbital radius of a geostationary satellite for a planet with...
The space shuttle releases a sattelite into a circular orbit 680 km above the Earth. How fast must the shuttle be moving (relative to the Earth's center) when the release occurs?
I know that G (m*m(earth)/r^2) = m (v^2/r)...with r = r(earth) + h. In this equation, r=6380+680=7060 km. There...
