Space Shuttle Atlantis successfully launched



Atlantis space shuttle with a crew of six astronauts was launched successfully to deliver a load of spare parts to the International Space Station. Space Shuttle had a successful launch from Pad 39A at 2:28Pm Easter Time on Monday, November 16.

THE ATLANTIS Space Shuttle had a successful launch from Pad 39A at 2:28Pm Easter Time on Monday, November 16. The Space shuttle launch took place at the Kennedy Space Centre, where the weather was quite nice and perfect. Also the countdown contained no serious technical issues as such.

The Space shuttle is on a mission of eleven days, designated STS 129 to carry the much needed spare parts to the International Space Station. Atlantis carried two spare gyroscopes, two nitrogen lank assemblies, two pump modules, ammonia tank assembly and spare latching end effectors for the station’s robotic arm.

Atlantis space shuttle is expected to arrive at the International Space Station in about two days after its launch.

NASA, in last month had successfully launched the prototype Ares I-X, the tallest rocket ever built as a part of its effort to build a new generation of space rocket to transport the Orion capsule.

The Atlantis space shuttle launch was the last launch in this year.

Satellite Radio


Satellite radio is one of the biggest improvements in broadcasting since the introduction of FM. Satellite radio signal can be broadcasted for more than 35,000 kilometers (22,000 miles) with complete clarity and high quality sound. You will never get static interferences while listening to over 100 radio channels. The idea behind satellite radio has appeared in 1992, when the United States Federal Communications Commission granted a spectrum of the S band (the 2.3 GHz frequency) for Digital Audio Radio Service. The license to broadcast in that band was allocated to Sirius Satellite Radio and XM Satellite Radio in 1997. Now there are three companies that provide satellite radio in the world: Sirius and XM in Northern America and WorldSpace in Asia, Europe and Africa.

Each of these companies offer different broadcasting systems, since the radio signal of each is proprietary. This means that you will have to buy different hardware depending on your subscription to one of these companies. However, there are three components common to all satellite radio services: the satellites, the ground repeaters and the radio receivers. Different satellite radio companies broadcast the radio signal in different ways. For instance, XM satellite radio uses geostationary satellites which have orbits that are synchronized with the movement of Earth. These satellites are located above the equator. In order to allow subscribers to receive crystal-clear signal despite obstacles such as buildings, hills or bridges, XM satellite radio service has installed a network of repeaters antennas that receive the radio signal from the satellites and retransmit it to the subscriber’s receiver Sirius, on the other hand, uses satellites that have unique elliptical orbits around Earth. These kinds of orbits allow satellites to get higher in the sky than geostationary satellites and this prevents loss of signal. This is the reason why Sirius has fewer terrestrial repeaters than XM.

The Advantages Of Satellite Radio

One of the great advantages of satellite radio is the fact that the programs are not interrupted by commercials. This is because the provider’s income comes from listeners and not from advertisers. Satellite radio services offer around 70 programs of commercial fee music channels each and you have a great variety of choices, from mainstream rock, hip-hop and dance music to folk music, opera, blues and many more.

Another great thing about satellite radio is the absence of static. You can be driving from the West Coast to the East Coast in the United States of America and you will not get any static at all on the way. The satellite radio signal is digital, which means that you will get crystal-clear sound wherever you go.

Satellite radio tuners receive, along with the actual radio programs, an influx of metadata that consists of information regarding song title, artist, radio program and radio channel. This means that your satellite radio receiver will display all the necessary information about what you are listening to. For instance, if you hear a great song and you want to know which artist sings it, you just look at the receiver‘s display.

All satellite radio programs are uncensored. This is one of the reasons why artists like Howard Stern chose to move their shows on satellite radio. You can also listen to your favorite hip-hop songs without the interruption of those annoying ‘beep’ sounds.

Satellite radio programs also offer information about local traffic and weather conditions. The information is very detailed especially for those who live in big cities. If there is a major national calamity and other terrestrial radio stations will not work, you can always count on getting accurate information from satellite radio program. You can also listen to satellite radio online on your computer.
