Hellas Planitia
This image from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter covers a small portion of the northwest quadrant of Hellas Planitia on Mars. With a diameter of about 1,400 miles and a depth reaching the lowest elevations on Mars, Hellas is one of the largest impact craters in the solar system.The area has a number of unusual features, which are thought to be quite old because of the high crater density. The crater inside Hellas has been filled with material, which may be related to volcanic activity on the basin's northwestern rim. It also might be related to the presence water and water ice. However, there is evidence elsewhere that the ground here is rich with ice. HiRISE will be used to investigate this in more detail when the basin is free from atmospheric dust.

Stellar Nursery in the Rosette Nebula
This image from the European Space Agency's Herschel Space Observatory shows the cloud associated with the Rosette Nebula, a stellar nursery about 5,000 light-years from Earth in the Monoceros, or Unicorn, constellation. Herschel collects the infrared light given out by dust. The bright smudges are dusty cocoons containing massive embryonic stars, which will grow up to 10 times the mass of our sun. The small spots near the center of the image are lower mass stellar embryos. The Rosette Nebula itself, and its massive cluster of stars, is located to the right of the picture. This image is a three-color composite showing infrared wavelengths of 70 microns (blue), 160 microns (green), and 250 microns (red). It was made with observations from Herschel's Photoconductor Array Camera and Spectrometer and the Spectral and Photometric Imaging Receiver instruments.Herschel is an ESA cornerstone mission, with science instruments provided by consortia of European institutes and with participation by NASA. A media day celebrating the release of the first results from ESA’s Herschel infrared space telescope will take place on May 6, 2010, at Space Expo, at the European Space Research and Technology Centre (ESTEC), Noordwijk, The Netherlands. Doors open at 11:30 CEST. The media day is organized in connection with the Herschel First Results Symposium taking place this week at ESTEC and the theme is Revealing the Hidden Side of Star Formation. For more information on the day's activities, see the press release.For more information on this image, visit ESA's Herschel Program site.

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.
