THE LATEST FROM SPACEWATCH
Among the most important people working in mission control are
the system flight controllers. Each one is responsible for a
specific aspect to each mission. This was Bob Carlton's job on
the Apollo missions. He also had to suffer through Armstrong's
"pranks" during simulation programs...Meet the man in the hot seat:
Bob "Control" Carlton, today at 2:00PM ET on an
all-new MISSION CONTROL, OVER.
-- UNIVERSE TODAY STORY SUMMARY --
* Searching for Aliens in Puerto Rico
* Ice Age Forest Discovered in Northern US
* NASA Cancels X-38 Test Flight due to Electrical Short
* New Hope for Gamma Ray Observatory
SEARCHING FOR ALIENS IN PUERTO RICO
Seth Shostak, and other SETI astronomers, monitor 28 million
channels for signs of alien life on the Arecibo radio telescope in
Puerto Rico. "Pipeline processing" helps to eliminate the signals
which are mere terrestrial interference, such as satellite signals,
versus those that originate in deep space.
ICE AGE FOREST DISCOVERED IN NORTHERN US
5 acres of almost perfectly preserved forest dating back to the
last ice age were uncovered by accident in a sand mining operation.
The ancient trees sprouted as the last glaciers retreated, then
were buried by water and sand due to rapidly increasing global
temperatures. Scientists analyze what the petrified forest might
teach us about today's changing global climate.
NASA CANCELS X-38 TEST FLIGHT DUE TO ELECTRICAL SHORT
The X-38 prototype is designed to be used as an emergency rescue
vehicle for the International Space Station. Electrical trouble,
possibly with the flight control system, happened minutes into the
final test preparations, preventing the X-38 from being released
from a B-52 at 35 000 feet, as intended.
NEW HOPE FOR GAMMA RAY OBSERVATORY
NASA may abort plans to deliberately crash the orbiting telescope
into the ocean this summer. Engineers may have found ways to keep
the observatory in orbit with back-up methods even if another of
its 3 gyroscopes fail. The ability to control the re-entry of the
GRO safely is the main factor in the debate whether to keep the
observatory in orbit.
