orbit

How could an artificial satellite be placed in orbit around mars? Once there why would it stay in orbit? If possible could you include details about rockets, rocket speeds, affect of lack of atmosphere Even useful websites would be really helpful! Thanks

Find the work required to launch a 1000-kg satellite vertically into orbit 1000 km high. You may assume that the earth's mass is 5000 x 10^24 kg and is concentrated at its center. The radius of the earth is 6.37x10^6 m and the gravitational constant is 6.67 x 10^-11 N*m^2/kg^2. (hint: convert...

Now that Iran is showing off it's capability to launch satellites, should the west be worried? Being that they now have the means to launch a warhead into orbit. Why is Israel waiting? Who doesn't see this as a ticking time bomb?

WIthout the cost of the satellite, of course

Is there an advantage, other than probably cost, to having the GPS satellites at 12,000 miles rather than in geostationary orbit? Would it work either way?

Why there is no mechanism for altering the trajectory? I think it would need a huge force to launch a satellite into circular orbit using a cannon buut why?

...move it to a geostationary orbit? I got 2.2x10^7 J...not sure bout that... Data: G=6.67e-11 Mass of earth =6e24

Determine? A satellite moves in a circular orbit around the Earth at a speed of 5034 m/s. Determine (a) the satellite's altitude above the surface of the Earth and (b) the period of the satellite's orbit.

is this possible? there are thousands of satellite which are active in space from lots of countries, placing along the governmental and secret satellites, do I have chance to BUY a satellite which already working in the orbit? ( if compnay wants to sell it?, are there any standards and laws for...

Say if China (or any other country) attacked and destroyed American GPS/spy/commercial satellites in orbit, what would be our response?

One way to attack a satellite in Earth orbit is to launch a swarm of pellets in the same orbit as the satellite but in the opposite direction. Suppose a satellite in a circular orbit 500 km above Earth's surface collides with a pellet having mass 4.0 g. a) What is the kinetic energy of this...

...heard of this on Art Bell,? Anything I hear about on Coast to Coast I take with a grain of salt, but this at least seems plausible.

(a) Find the time of one revolution. (b) Find the radial acceleration of the satellite in its orbit.

...Earth at a height of 3600 km? Mass of Earth: 5.98 E 24 kg Equatorial Radius of the Earth: 6.378 E 3 I'm not sure if these are needed for this problem but I provided them just in case. This was everything that was given. I'm not sure this problem is even possible..

These orbits have to be circular. Calculate how high above the earth's surface a satellite in a geosynchronous orbit has to be. The only information needed is the mass of the earth (-6.4 x 10^24kg) and the radius of the earth (-6.4 x 10^6m) It is not good enough to give just the answer (35.8m)...

...(LEO) with an eccentricity of 0.5.......? Determine the apogee and perigee for a satellite in a low earth orbit (LEO) with an eccentricity of 0.5 and a semi-major axis of 8320 miles. Thanks in advance.

ALOOOT... somewhere in the millions
