China Analyst: U.S. Can’t Win in Space, So Why Bother Racing?
With access to more than 400 satellites plus at least two tiny, maneuverable robotic shuttles, the U.S. military is the clear leader in military spacecraft. But with 70 orbiters of its own, China is catching up fast. Last year, Beijing matched Washington in space launches for the first time, boosting no fewer than 15 satellites into orbit. It was the first time any nation kept a celestial pace with the U.S. since the height of the Cold War.
The new space race is on. But in the view of one influential analyst, the race isn’t worth the prize. Space “is expensive to enter, hard to sustain assets in, contains no defensive ground, and — barring energy-intensive maneuvering – forces assets into predictable orbits,” Andrew Erickson, a Naval War College professor and editor of the new book Chinese Aerospace Power, told me as part of a longer interview over at AOL Defense.
No one disputes that China is gaining “ground” in space. “The [People’s Liberation Army] is acquiring a range of Read more…
Farthest, Largest Water Mass In Universe Discovered
International Space Station crew forced to evacuate
The six-member crew of the International Space Station wereforced to evacuate to two Russian Soyuz rescue space vehicles after spotting incoming debris that threatened to flatten the fragile craft
The space junk missed the craft by 820ft, a Russian space industry source tolkd the Interfax news agency
“The space junk was detected too late for a ducking manoeuvre,” the source told Interfax.
“The six ISS crew members received instructions to transfer to the Soyuz vehicles,” the Russian source said.
An official at Russian space control outside Moscow said by telephone that such incidents had occurred on past occasions and did not represent an emergency.
“If this is true, they would be following the normal procedure for evacuating the station if necessary,” the mission control spokesman said.
“This is not an emergency operation. They have standing instructions to that effect,” the spokeswoman said.
Three crew members were forced to briefly evacuate the ISS in an incident in March 2009.
It was not immediately clear when the debris was expected to approach the station or what precisely was detected.
The crew is currently manned by three Russians and two Americans as well as a Japanese astronaut.
‘Dramatic’ solar flare could disrupt Earth communications
Handout photo released by NASA Earth Observatory on June 7, 2011 and taken from NASA’s Solar Dynamics Observatory (SDO), sunspot complex 1226-1227, shows the Sun unleashing an M-2 (medium-sized) solar flare.
WASHINGTON – An unusual solar flare observed by a NASA space observatory on Tuesday could cause some disruptions to satellite communications and power on Earth over the next day or so, officials said.
The potent blast from the Sun unleashed a firestorm of radiation on a level not witnessed since 2006, and will likely lead to moderate geomagnetic storm activity by Wednesday, according to the National Weather Service.
“This one was rather dramatic,” said Bill Murtagh, program coordinator at the NWS’s Space Weather Prediction Center, describing the M-2 (medium-sized) solar flare that peaked at 1:41 a.m. Eastern time in North America, or 0541 GMT.
“We saw the initial flare occurring and Read more…
Solar flaring warning issued

Cape Town – The Space Weather Centre has warned that the sun is undergoing some instability, which has implications for electronic communications.
“There is a very active area on the sun as rotated onto the invisible solar disc. This active area has got the potential for more flaring for the next five to six days,” space weather forecaster Kobus Olckers of the Space Weather Warning Centre at the Hermanus Magnetic Observatory told News24.
He said that communications and electronic systems might be affected.
“The internet could be a little slower for the next week or so and especially long distance communications.”

Chinese space plans cause military jitters
China has announced plans to put its own space station in orbit by 2020. The 60-tonne construction will be one-seventh the weight of the ISS and will focus on scientific experiments. However, military involvement with the project is causing concern.
Beijing’s Space City research center is opening its doors to the media, as China has announced its intention to build a rival to the International Space Station.
While some see Chinese advances in space travel as a potential threat, the country’s officials are keen to stress the spirit of co-operation, which they say is behind China’s space program.
“We are looking forward to co-operating with other countries in the field of space exploration,” said Yang Liwei, Vice Director of Manned Space Engineering Bureau. “We are also looking forward to having more countries join this club, so we can promote the common goals of mankind.”
For the moment though, the Chinese space program is doing very well on its own.
Since becoming only the third country in the world to send a person in to space, in 2003, the Chinese also carried out a space walk in 2008 and the Read more…
China unveils rival to International Space Station
Less than a decade ago, it fired its first human being into orbit. Now, Beijing is working on a multi-capsule outpost in space. But what is the political message of the Tiangong ‘heavenly palace’?

China laid out plans for its future in space yesterday, unveiling details of an ambitious new space station to be built in orbit within a decade.
The project, which one NASA adviser describes as a “potent political symbol”, is the latest phase in China’s rapidly developing space programme. It is less than a decade since China put a human into orbit for the first time, and three years since its first spacewalk.
The space station will weigh around 60 tonnes and consist of a core module with two laboratory units for experiments, according to the state news agency, Xinhua.
Officials have asked the public to suggest names and symbols for the unit and for a cargo spacecraft that will serve it.
Professor Jiang Guohua, from the China Astronaut Research and Training Centre, said the facility would be designed to Read more…
Russian Lawmakers to Warn Against Space-Based WMD
The KS battle station. Stripped surplus Buran test articles are docked to the core. They would act as nuclear weapon dispensers.
The lower house of Russia’s parliament was set on Monday to back a decree opposing any deployment of weapons of mass destruction in outer space, Interfax quoted the body’s executive service as saying on Saturday (see GSN, Aug. 11, 2009).
The State Duma decree, titled “In Connection with the 50th Anniversary of the First Manned Space Flight,” was slated for consideration before a Tuesday celebration of the April 12, 1961, flight of cosmonaut Yuri Gagarin.
“Russia takes consistent action to prevent the deployment of offensive armaments and an arms race in space,” though space systems are key to Russia’s defense, the preliminary document says.
“It is impossible to give a modern image to the armed forces of the Russian Federation and achieve high battle readiness and effectiveness for them without space systems of satellite intelligence, communications, targeting, navigation, missile attack warning and means of space missile defense,” the statement says (Interfax, April 9).
Impact of space weather threat examined
Professor Hapgood examines the linkage between the science of space weather and its impact on technological systems, potential impact of Solar weather on orbital and ground based systems including power, energy and communications – as well as atmospheric physics.
Space weather is concerned with disturbances in Earth’s upper atmosphere and in near-Earth space that can disrupt the advanced technologies on which our society now relies. A proper understanding of space weather requires us to bring together a range of scientific, engineering and economic expertise, emphasizing the role of the electromagnetic force in many of the physical processes that cause space weather.
One example is the crucial role of plasma physics within the sources of space weather on the Sun, in the transmission of energy from the Sun to the Earth via the solar wind and Earth’s magnetosphere.
Another is the role of the electric currents that naturally flow with Read more…

WASHINGTON — The U.S. military needs to better protect its satellites and strengthen its ability to use them as weapons as the uncharted battlefield of space becomes increasingly crowded and dangerous, Pentagon leaders say. A new military strategy for space, as mapped out by the Pentagon, calls for greater cooperation with other nations on space-based programs to improve America’s ability to deter enemies. “It’s a domain, like air land and sea,” said Gen. Kevin Chilton, who led U.S. Strategic Command until he retired late last month. “Space is not just a Read more…
