Constellation Animation in HD
NASA plans to develop a host of spacecraft and booster vehicles in order to replace the Space Shuttle and send astronauts to the Moon and possibly to Mars as well. Currently, NASA is in the process of designing two boosters, the Ares I and Ares V. Ares I will have the sole function of launching mission crews into orbit. Ares V will be designed to launch other hardware for use on missions and will have a heavier lift capacity than the Ares I booster. In addition to these two boosters, NASA is designing a set of other spacecraft for use during Constellation. These will include the Orion crew capsule, the Earth Departure Stage and the Altair lunar lander.

STS-129 HD Launch
Space shuttle Atlantis and its six-member crew began an 11-day delivery flight to the International Space Station on Monday with a 2:28 p.m. EST launch from NASA's Kennedy Space Center in Florida. The shuttle will transport spare hardware to the outpost and return a station crew member who spent more than two months in space.
Atlantis is carrying about 30,000 pounds of replacement parts for systems that provide power to the station, keep it from overheating, and maintain a proper orientation in space. The large equipment can best be transported using the shuttle's unique capabilities.

SATELLITE:
A satellite is any object that revolves in a curved path around a planet.
There are two major types of categorization when it comes down to satellites, one is natural Satellite and the other is artificial satellite.
A Natural Satellite is any celestial body in space that orbits around a larger body.
Satellites that are made by people and launched into orbit using rockets are called Artificial Satellites.
TYPES OF satellite orbits:
By Inclination,
Equatorial orbit:
An equatorial orbit is when the satellite rotates in an orbit directly above the equator,
usually in a circular path. with an equatorial orbit, the angle of inclination is 00 degrees.
It has an inclination of 0°.
Inclined orbit:
Inclined orbits are virtually all orbits except those that travel directly above the equator or directly above the North and South Poles. The angle of inclination vary between 0 to 180 degrees.
Polar orbit:
A polar orbit is when the satellite rotates in a path that takes it over the North and South Poles in an orbital pattern that is perpendicular to the equatorial plane.Polar orbiting satellites follow a low altitude path close to earth’s surface, passing over and very close to both the North and South Poles.
The angle of inclination of a satellite in a polar orbit is nearly 90 degrees.
On the basis of the altitude from Earth, the types of orbits are classified into:
• Low Earth orbit (LEO):
Low earth orbit satellites operate at a distance of about 160 to 2,000 kilometres above the earth's surface.
It takes approximately 90 to 120 minutes to circle the Earth.
• Medium earth orbit (MEO):
Medium earth orbit is the region of space around the Earth above low Earth orbit and below geostationary orbit.
The orbital periods of Medium earth orbit satellites range from about two to six hours.
This satellite operates at altitudes between 2,000 kilometers and 35,786 kilometers above the earth’s surface.
• Geostationary earth orbit (GEO):
A geostationary satellite is an earth-orbiting satellite. it placed at an altitude of approximately 35,786 kilometers directly over the equator, that revolves in the same direction the earth rotates that means west to east.
This satellite takes 24 hours to orbit the Earth.
Orbits are also classified into two types on the basis of the shape:
• Circular orbit
• Elliptical orbit
Circular orbit:
Circular orbit is the orbit with a fixed distance around the barycenter, that is, in the shape of a circle. This orbits has an eccentricity of 0.
There are several types of circular orbits and they include:
• Geostationary Orbit
• Polar Orbit
• Equatorial orbit
Elliptical Orbit:
An elliptical orbit is the revolving of one object around another in an oval-shaped path called an ellipse.
The eccentricity of an elliptical orbit is greater than 0 but less than 1.
Sometimes these satellites are closer, and at other times they are farther away from earth.
The closest point a satellite comes to Earth is called its perigee.
The farthest point is the apogee.
The most common example of elliptical orbit is highly elliptical orbit.
Types of artificial satellites
Navigation satellite:
A satellite navigation system used to determine the ground position of an object.
It determines the geographic location of ships, aircrafts, or any other object.
It is also vital to military forces.
It is often used for gathering intelligence used for military purposes or as a military weapon.
Weather satellite:
Weather satellites are primarily used-
✓ to monitor the weather and climate of the Earth.
✓ to predict daily weather conditions, such as temperature and rainfall.
✓ to monitor how weather conditions, like storms, hurricanes, cyclone, tropical storms,
develop and change over time.
Communications satellite
The communication satellite is a satellite that transmits the signals such as telephone, television, radio, internet signals over long distances.

Rocket Science and orbital mechanics of Satellites.
There are about 3000 operational satellites, owned by over 100 different countries orbiting the earth right now. About 550 of these are in geo stationary orbits - the satellite appears stationary compared to the rotation of the earth. Communications satellites are typically in such orbits. These allow you to leave your satellite dish in one position, and never have to change it.
Orbital mechanics is rooted in Keppler’s laws of planetary motion & Newton’s laws of universal gravitation.
These laws allow us to calculate the period and speed of such a satellite.
Speed = S = sq root(mu/r) mu= standard gravitational parameter
Period = T = 2pi*sq root(r^3/mu)
r = radius of orbit = altitude + radius of earth
mu = Newton’s universal gravitational constant x mass of planet
A geostationary orbit is 35,786 km from the equator. The orbital period is 23.93 hours, or 23 hours 56 minutes which is the time it actually takes for the earth to complete one rotation. The reason we normally count 24 hours as being one day, is because 24 hours is the precise time the sun is at the same spot in the sky every day.
To got into its orbit, the satellite is launched on a rocket. In the United States, one workhorse rocket has been the Atlas V. It weighs 700,000 lbs at launch and can lift 28,000 lbs to geostationary orbit. The main engine is powered by liquid oxygen, the oxidizer and RP-1 – which is form of kerosene, similar to jet fuel.
Rocket engines are an application of Newton’s third law, for every action, there is an equal and opposite reaction. The combustion of fuel causes high pressure exhaust gases to be expelled at supersonic speed. The rearward acceleration of the mass of the fuel leaving the rocket nozzle causes the equal and opposite reaction of forward thrust powering the rocket upward.
Maintaining a stable straight flight comes from swiveling the thrust nozzle to keep it stable. This is called gimbaled thrust.
A geosynchronous orbit is achieved in stages. Typically, the rocket takes the satellite on its orbital altitude, but the initial orbit is elliptical. This elliptical orbit has to be changed to a circular orbit to become geostationary. The satellite continues on an elliptical orbit until accelerating the rocket at precisely the right time during its trajectory forms a circular orbit at the geostationary distance, which is at 35,786 km above the earth’s equator. There is no other geostationary orbit.
Since there are 500 satellites at that altitude, the real estate is limited. This real estate at the geo stationary orbit is tightly controlled by an organization called, the international telecommunications union (ITU) which assigns each satellite a slot at this perimeter.
In addition, unless the rocket is launched from somewhere in the equator, it will have an orbit that is not quite geo stationary because it will not be in line or in the same plane relative to the equator. So for example, when satellites are launched from Cape Canaveral, which is located at about 28.5 degrees north latitude, the orbit will be inclined 28.5 degrees from the equator. This has to be adjusted, in a directional change requiring fuel. Thus, it is beneficial for countries to launch their rockets as close to the equator as possible so that less rocket fuel is needed to make this adjustment.
The first thing that happens after a satellite reaches its permanent orbit is that solar panels are deployed so that the satellite can have power to function. It orients itself relative to the sun and the earth, and establishes communication links. The main function of the satellite is to receive signals from earth mainly in the form of radio transmissions, amplify them, and relay them back at a different frequency back to the surface of the earth. The shift in frequency is used to prevent interference of incoming signals with outgoing signals.

Since radio waves are a form of electromagnetic radiation, same as visible light, they do not bend around the curvature of earth – photons are too fast after all, the job of the satellite is to transmit radio waves over long distances. Otherwise, this would require a string of thousands of relay stations on earth to do the same task.
Interestingly, a geostationary orbit is sometimes called the Clarke orbit, named for science fiction writer Arthur C. Clarke, who wrote 2001-a space odyssey. Believe it or not, he was the first person to detail the usefulness of such an orbit in a story he wrote back in 1945.

Rocket Science and orbital mechanics of Satellites.
There are about 3000 operational satellites, owned by over 100 different countries orbiting the earth right now. About 550 of these are in geo stationary orbits - the satellite appears stationary compared to the rotation of the earth. Communications satellites are typically in such orbits. These allow you to leave your satellite dish in one position, and never have to change it.
Orbital mechanics is rooted in Keppler’s laws of planetary motion & Newton’s laws of universal gravitation.
These laws allow us to calculate the period and speed of such a satellite.
Speed = S = sq root(mu/r) mu= standard gravitational parameter
Period = T = 2pi*sq root(r^3/mu)
r = radius of orbit = altitude + radius of earth
mu = Newton’s universal gravitational constant x mass of planet
A geostationary orbit is 35,786 km from the equator. The orbital period is 23.93 hours, or 23 hours 56 minutes which is the time it actually takes for the earth to complete one rotation. The reason we normally count 24 hours as being one day, is because 24 hours is the precise time the sun is at the same spot in the sky every day.
To got into its orbit, the satellite is launched on a rocket. In the United States, one workhorse rocket has been the Atlas V. It weighs 700,000 lbs at launch and can lift 28,000 lbs to geostationary orbit. The main engine is powered by liquid oxygen, the oxidizer and RP-1 – which is form of kerosene, similar to jet fuel.
Rocket engines are an application of Newton’s third law, for every action, there is an equal and opposite reaction. The combustion of fuel causes high pressure exhaust gases to be expelled at supersonic speed. The rearward acceleration of the mass of the fuel leaving the rocket nozzle causes the equal and opposite reaction of forward thrust powering the rocket upward.
Maintaining a stable straight flight comes from swiveling the thrust nozzle to keep it stable. This is called gimbaled thrust.
A geosynchronous orbit is achieved in stages. Typically, the rocket takes the satellite on its orbital altitude, but the initial orbit is elliptical. This elliptical orbit has to be changed to a circular orbit to become geostationary. The satellite continues on an elliptical orbit until accelerating the rocket at precisely the right time during its trajectory forms a circular orbit at the geostationary distance, which is at 35,786 km above the earth’s equator. There is no other geostationary orbit.
Since there are 500 satellites at that altitude, the real estate is limited. This real estate at the geo stationary orbit is tightly controlled by an organization called, the international telecommunications union (ITU) which assigns each satellite a slot at this perimeter.
In addition, unless the rocket is launched from somewhere in the equator, it will have an orbit that is not quite geo stationary because it will not be in line or in the same plane relative to the equator.

Space shuttle Atlantis and its six-member crew began an 11-day delivery flight to the International Space Station on Monday with a 2:28 p.m. EST launch from NASA's Kennedy Space Center in Florida. The shuttle will transport spare hardware to the outpost and return a station crew member who spent more than two months in space.
Atlantis is carrying about 30,000 pounds of replacement parts for systems that provide power to the station, keep it from overheating, and maintain a proper orientation in space. The large equipment can best be transported using the shuttle's unique capabilities.
