ISS Photography: 100 Million Words
Commander Jeff Williams and Flight Engineers Max Suraev, Oleg Kotov, T.J. Creamer, and Soichi Noguchi are expected to snap a total of 100,000 images by the end of their mission in Earth orbit.
If a picture is worth a thousand words, then the Expedition 22 crew aboard the International Space Station is about to complete the generation of 100 million words worth of information. That’s because Commander Jeff Williams and Flight Engineers Max Suraev, Oleg Kotov, T.J. Creamer, and Soichi Noguchi are expected to snap a total of 100,000 images by the end of their mission in Earth orbit. Williams is setting a record that surpasses his own previous record of 83,856 images taken during Expedition 13 in 2006. “This week we broke my old Exp. 13 record for number of Earth photos,” Williams “tweeted” from the station. “Later, after landing and recovery, I will post some of best.” Among those digital still images is this spectacular nighttime image taken of Houston, Texas, the home of Mission Control and astronaut training, and the hub of the International Space Station Program that unites five space agencies and 15 countries in peaceful exploration and scientific research. Williams and Suraev will end their five-and-a-half-month stay on the station Thursday, when they undock their Soyuz spacecraft and head for a landing in Kazakhstan. They were part of both the Expedition 21 and 22 crews. Kotov, Creamer and Noguchi will stay on orbit, snapping more photos, for two more months before returning home after being part of both the Expedition 22 and 23 crews. All told, space station crews so far have amassed a total of almost 639,000 images. Those images include photos that document life and work aboard the space station, and photos that document the condition of the home planet from its unique perspective 220 miles above Earth. Their efforts are part of a larger collection that began with Earth observations photos during the Gemini Program of the 1960s. Many of the images are used in scientific research about the Earth, its climate, its resources and the effects humans are having on both.
The recent STS-130 space shuttle mission delivered a new observation deck known as the cupola that offers the largest window ever flown on a spacecraft, and the upcoming STS-131 shuttle mission to the station will deliver the Window Observational Research Facility (WORF), which will provide a new facility dedicated to multi- and hyper-spectral remote sensing and high resolution Earth observation photography to enhance the use of the best optical-quality window ever flown in space, in the U.S. Destiny Laboratory.

ABOUT AMATEUR RADIO
Amateur radio service is defined in the Communication and Multimedia (Spectrum) Regulations 2000 as a radiocommunications service (covering both terrestrial and satellite) in which a station is used for the purpose of self traning, intercommunication and technical investigations carried out by authorized persons who are interested in radio technique solely with a personal aim and without any pecuniary interest.
AMATEUR RADIO OPERATOR'S CERTIFICATE
Regulation 27(1) of the Communications and Multimedia (Technical Standards) Regulations 2000 states that no person shall undertake or conduct any activity in designated skil area unless that person is certified. Amateur radio operator has been gazetted as a designated skill area category under the regulation, hence to operate an amateur radio station a person needs to have an appropriate proficiency and skill i.e. certified in this area.
INTERFERENCE
Please ensure that the radio transmision does not cause interference to any other radio services. Regulation 15(1) of the Communications and Multemedia (Technical Standards) Regulations 2000 states that no person shall intentionally design, install, operate, maintain or modify any communications equipment in a manner is likely to cause interference with, impairment, mulfunction of, or harm to any communications equipment or any other equipment.
Regulation 15(2) of the regulation denotes that a person who contravenes this regulation commits an offence and shall, on conviction, be liable to a fine not exceeding three hundred thousand ringgit (RM 300,000.00) or to imprisonment for a term of not exceeding three years or to both.
To eliminate the potential of interferences, the following procedures must be followed strictly:-
a) Ensure that suffient equipment, tools and test gear is available and can used to monitor and verify that your transmission does not cause any interference to other radio services.
b) You must responsible if your amateur radio is found to be the caused of interference. Immediate remedy action must be taken to rectify the problems in case of interference.
c) Ensure that the transmission do not exceed the level of over deviation.
d) Ensure that the radiated energy is always within the narrowest posible frequency bands for any class of emission in use.
e) The radiation of harmonics and spurious emissions should be suppressed to minimize interference.

Historical Description of Amateur Radio: From the Encyclopedia Britannica:-
Interest in amateur radio arose around the turn of the century, shortly after the Italian inventor Guglielmo Marconi successfully sent the first transatlantic wireless signal in 1901. The interference of amateur broadcasts with commercial and military transmissions led to the institution of government control in 1911. After World War I, amateurs became active in radio experimentation, contributing to developments in long-distance broadcasting and becoming the first radio operators successfully to exploit the upper medium-frequency and lower high-frequency radio bands. Over the years, amateur radio operators have also provided emergency communications during forest fires, floods, hurricanes, and other disasters. They serve as an important link between stricken communities and the outside world until normal communications are reestablished.Amateur radio operators in the United States are subject to international and federal regulations. There are five classes of licenses. Competence in the use of the International Morse Code and a knowledge of radio theory and regulation are required to obtain the advanced-level licenses. Amateur radio is allocated frequencies at the extreme high-frequency end of the medium-wave band, five groups of frequencies in the shortwave band, two groups in the veryhigh-frequency band, three in the ultrahigh-frequency band, and seven in the superhigh-frequency band for telegraphic and telephonic communication using amplitude and frequency modulation. There are restrictions on the power of the transmitters, and certain of the frequencies must be shared with due regard for the needs of other users.
