同 盟 国 は 宇 宙 資 産 を 防 衛 するために 結 束 する
Allies unite in bid to defend space assets
AUSTRALIA will join forces with the US to help protect satellite communications from deliberate sabotage.
The move comes at a time when foreign powers such as China
are increasingly asserting their authority in space. The move is
aimed at ensuring the US and its allies maintain their dominance
in space, which is fast emerging as a battleground of the future.
The joint partnership, announced at yesterday's Ausmin meeting
in Melbourne, mentioned China as a country that had taken
"deliberate actions" to disrupt the operating environment for
satellites in space. "Space is becoming increasingly congested
due to the debris from over 50 years of space activities," the US
and Australia said in a joint statement. "Debris can result from
deliberate actions such as the 2007 Chinese anti-satellite test,
which added over 6000 pieces of orbiting debris." The statement
said the development of counter-space weapons that created
more long-lived space debris posed "a direct and immediate
threat to the rights of all nations to explore and use space for
peaceful purposes". The joint partnership is likely to lead to US
space sensors operating from joint facilities such as the Naval
Communications Station at Exmouth in Western Australia. The
collisions and gauge whether some accidents were deliberate
acts of sabotage by foreign powers. The partnership is also
designed to protect the Australian Defence Force, which relies
heavily on space-based communications. "Space is critical to a
variety of ADF systems as well as successful operations," the
two countries said in a joint statement. "It is also important to
broader national security interests, including intelligence
collection." An effective attack against space-based
communication systems would also affect aircraft and ship
navigation, weather forecasting, disaster recovery and
international phone networks. "The benefits of free use of space
permeate almost every facet of our daily lives," the Ausmin
statement said. Currently, 16,000 space objects, including
satellites and space junk, are tracked by the US. A recent report
by the Kokoda Foundation think tank called for Australia to do
more to defend its strategic interests in space, saying the federal
government needed to develop a more comprehensive space
policy.

Aerojet のエンジンは Delta Ii の 第 2 段 を 駆 動 し、COSMO-SkyMed コンステレーションを 打 上 げ
Aerojet's Engine Powers Delta II Second Stage for the COSMO-SkyMed Constellation
SACRAMENTO, Calif., Nov. 8, 2010 /PRNewswire-FirstCall/ --
Aerojet, a GenCorp (NYSE:GY - News) company, announced that
its engine helped propel Friday night's launch of the Delta II
launch vehicle from Vandenberg Air Force Base (VAFB) in Calif.
This is the fourth launch, completing the COSMO-SkyMed
constellation. The overall objective of the COSMO-SkyMed
program is global Earth observation, particularly in the
Mediterranean area. Some applications of this constellation
include analyzing effects of natural disasters; coastal surveillance
to assess erosion and sea/river pollution, monitoring of farming,
mapping forestry resources and urban buildings; and territorial
security and strategic defense. The first three COSMO-SkyMed
satellites were launched from Vandenberg in June 2007, Dec.
2007 and Oct. 2008, respectively. The Delta II launch vehicle will
deliver COSMO-4 into the same orbit as COSMO-1, COSMO-2
and COSMO-3, where it will begin its dual-use mission of data
observation and data recording for the needs of both the military
and civilian communities. Under contract to the United Launch
Alliance, Aerojet provides the Delta II rocket's liquid second
stage engine. This same engine has supported numerous
launches of critical NASA and Air Force missions. Aerojet's
second stage engine has delivered payloads for NASA's space
exploration such as MESSENGER, Phoenix Mars Lander, GLAST,
THEMIS, STEREO, Deep Impact and the Mars Exploration Rovers,
Spirit and Opportunity, as well as the USAF Global Positioning
System (GPS) Block IIR fleet. "It's rewarding to be part of the
team that is delivering this Earth observation program for the
Italian Space Agency," said Delta II Program Manager Eric Veith.
Aerojet is a world-recognized aerospace and defense leader
principally serving the missile and space propulsion, defense and
armaments markets. GenCorp is a leading technology-based
manufacturer of aerospace and defense products and systems
with a real estate segment that includes activities related to the
entitlement, sale, and leasing of the company's excess real
