AMSAT News Service Bulletin 116.06 From AMSAT HQ
SILVER SPRING, MD. April 25, 2004
To All RADIO AMATEURS
BID: $ANS-116.06
** After 70 years on the air, Swiss Radio International has reached the
final phase of its retreat from international radio broadcasting. As
of April 13th there are no more daily radio programs in English, and at
the end of October the shortwave transmissions will close down
completely. --Newsline
** NASA's Gravity Probe B (GP-B) space vehicle, built, integrated and
tested by Lockheed Martin, roared into space on 20 April 2004 from
Vandenberg Air Force Base, Calif. Stanford University is the GP-B prime
contractor. NASA Marshall Space Flight Center in Huntsville, Ala. Manages
the program. During its 16-month mission, GP-B will attempt to verify two
subtle physical effects predicted by Albert Einstein's General Theory of
Relativity, which provides the foundations for understanding the large-scale
structure of the Universe. --SpaceDaily
** Scientists have found clues that dust devils on Mars might have
high-voltage electric fields, based on observations of their terrestrial
counterpart. This research supports NASA's Vision for Space Exploration by
helping to understand what challenges the Martian environment presents to
explorers, both robotic and eventually human. NASA and university
researchers discovered that dust devils on Earth have unexpectedly large
electric fields, in excess of 4,000 volts per meter (yard), and can generate
magnetic fields as well. --SpaceDaily
** NASA's Dryden Flight Research Center, the U.S. Air Force Flight Test
Center (AFFTC), and Blacksky Corporation joined forces on the prairie lands
of West Texas recently to fly small aerospike rocket nozzles. The effort,
called the Dryden Aerospike Rocket Test, yielded big returns, providing the
first known data from a solid-fueled aerospike rocket in flight. Two 10-ft.
Long solid-fueled rockets with aerospike nozzles were flown successfully on
two consecutive flights March 30 and 31, 2004. Under perfect skies and calm
winds, the rockets ascended from the King Ranch launch site at the Pecos
County Aerospace Development Corporation Flight Test Range in Fort Stockton,
Texas. --SpaceDaily
