The 34-year odyssey of NASA's Voyager 1 spacecraft has reached a
distant point at the edge of our solar system where there is no
outward motion of solar wind. The event is a major milestone in
Voyager 1's passage through the heliosheath, the turbulent outer
shell of the sun's sphere of influence, and the spacecraft's
upcoming departure from our solar system.
CCIE Funded By NASA's Aeronautics Research Mission
Aeronautics researchers at NASA's Dryden Flight Research Center
recently completed flight tests of a unique experimental jet engine
inlet design in the Channeled Center-body Inlet Experiment, or
CCIE. The experimental inlet was checked out on NASA Dryden's F-15B
aeronautics research test bed aircraft, which continues to be an
innovative and cost-effective tool for flight test of advanced
propulsion concepts. The CCIE project's primary research objective
was to define the airflow through the experimental jet engine
inlet, then compare it to the airflow through a standard inlet.
Inside, airflow around two interchangeable center bodies installed
in an air inlet tube was measured. The structures are designed to
On Wednesday, December 28, Arianespace and Starsem orbited six
new satellites of the Globalstar-2 constellation. The 1,784th
launch of a Soyuz family rocket (Soyuz-Fregat version) took place
at the Baikonur Cosmodrome in Kazakhstan. The launcher lifted off
at 17:09 Universal Time on Wednesday, December 28, 2011 (11:09 pm
local time, 6:09 pm in Paris, and 9:09 am in San Francisco).
Arianespace, Starsem and their Russian partners confirmed that the
Fregat orbital stage accurately injected the six Globalstar-2
satellites into their targeted orbit.
Now... this what we call celebrating the holiday... with further
exploration of our Moon. NASA's twin spacecraft to study the moon
from crust to core are nearing their New Year's Eve and New Year's
Day main-engine burns to place the duo in lunar orbit. Named
Gravity Recovery And Interior Laboratory (GRAIL), the spacecraft
are scheduled to be placed in orbit beginning at 1:21 p.m. PST
(4:21 p.m. EST) for GRAIL-A on Dec. 31, and 2:05 p.m. PST (5:05
p.m. EST) on Jan. 1 for GRAIL-B.
