ASTRONOMY GEOGRAPHIC ADVANTAGE BILL TO BE LAW SOON

It is expected that the Astronomy Geographic Advantage bill will soon be signed into law. The new law will provide for the preservation and protection of the areas within South Africa that are uniquely suited for optical and radio astronomy and to provide for the intergovernmental co-operation and public consultation on matters concerning national significant astronomy advantage areas.

The new act gives the Minister of Science and Technology a wide range of powers to declare areas where the Square Kilometre Array project is likely to be established a radio frequency restricted zone. Rural areas of the Northern Cape will be the main area to be affected. While the act may sound harsh, there are a number of safeguards built in to consult with other users of the radio spectrum.

At a recent frequency spectrum planning conference arranged by IQPC Adrian Tripleplay of the SKA project said that the SKA team had been consulting with various industry bodies and service providers to seek alternative methods of providing communication and television services in areas that may be affected. The South African Radio League showed particular concern about possible restriction of mobile radio operation in the area. Adrian Triplepay was interviewed by the SARL’s Amateur Radio Mirror International. To listen click here

 


NAME THAT SPACE TELESCOPE

NASA is inviting members of the general public from around the world to suggest a new name for the Gamma-ray Large Area Space Telescope, otherwise known as GLAST, before it launches in mid-2008. GLAST is designed to probe the most violent events and exotic objects in the cosmos from gamma-ray bursts to black holes and beyond.

"We're looking for suggestions that will capture the excitement of GLAST's mission and call attention to gamma-ray and high-energy astronomy," says Alan Stern, associate administrator for Science at NASA Headquarters in Washington DC. "We hope someone will come up with a name that is catchy, easy to say and will help make the satellite and its mission a topic of dinner table and classroom discussion."

The telescope's key scientific objectives include:

  • Exploring the most extreme environments in the Universe, where nature harnesses energies far beyond anything possible on Earth
  • Searching for signs of new laws of physics and what composes the mysterious dark matter
  • Understanding how black holes accelerate immense jets of material to nearly light speed
  • Cracking the mysteries of stupendously powerful explosions known as gamma-ray bursts
  • Answering long-standing questions about solar flares, pulsars and the origin of cosmic rays

Suggestions for the mission's new name may be an acronym, but that is not a requirement. Any suggestions for naming the telescope after a scientist may only include names of deceased scientists whose names are not already used for other NASA missions. All suggestions will be considered. The period for accepting names closes on March 31, 2008. Participants must include a statement of 25 words or less about why their suggestion would be a strong name for the mission. Multiple suggestions are encouraged.

To submit a suggestion for the mission name, visit: http://glast.sonoma.edu/glastname

Anyone who drops a name into the "Name That Satellite!" suggestion box on the Web page can choose to receive a "Certificate of Participation" via return e-mail. Participants also may choose to receive the NASA press release announcing the new mission name. The announcement is expected approximately 60 days after launch of the telescope.

SOLAR CYCLE 24 WHAT IS LIKELY IN STORE ?

Listen to this 3 part series  with host Hap Holley of the Rain Report  as he interviews  Propagation columnist Tomas Hood, NW7US

Part 1
Part 2
Part 3

From his home studio/ham shack in suburban Chicago, Hap Holly, KC9RP, produces this 10 to 15- minute weekly amateur radio programme service, featuring timely interviews, occasional thought-provoking commentaries from other hams, excerpts from Hamvention Forums and other items of general interest to the ham radio community at large. Ham radio is traditionally an aural - as opposed to a visual - medium; we meet and recognize fellow hams primarily by voice, seldom seeing them in person. RAIN programming is also an aural medium, listened to by thousands of Internet users and hundreds of repeaters across the world at http://www.therainreport.com, The rain Report can frequently be heard on Amateur Radio Mirror International
