America’s Space Weakness
On August 15, 2010, the U.S. Air Force almost lost a $2-billion communications satellite. A team of military and contract space operators eventually saved the Advanced Extremely High Frequency satellite, built by Lockheed Martin. But the rescue, admittedly an impressive technological feat, is also a window into the greatest weaknesses of the world’s leading space power, according to one space insider.The seven-ton “AEHF-1,” part of a planned six-satellite constellation meant to support radio communication between far-flung U.S. military units, had been in orbit just one day when the problems began. The satellite started out in a highly-elliptical, temporary orbit. The plan was to use the spacecraft’s on-board engine to boost it to a permanent, geo-stationary orbit. But when the Air Force space operators at Los Angeles Air Force Base activated the engine, nothing happened. The Government Accountability Office would later blame Read more…
NASA Satellite Falling: Will It Hit You?
A NASA satellite is expected to make a crash landing on Earth in late September or early October. No one knows where it will land, not even NASA. It could even land on you — but luckily, you have a better chance of winning the lottery than of having a piece of the satellite fall on your head.
According to Nicholas Johnson, NASA’s chief scientist for orbital debris (yes, there is such a job), the odds of any specific person getting hit are about 1 in 21 trillion, MSNBC reported. That’s a chance of about 0.0000000001 percent. For perspective, the odds of any given person winning the lottery are 1 in hundreds of billions, depending on the lottery design — but nowhere near the trillions.
There is a much greater, but still minimal, chance that a piece of the satellite will hit someone on Earth: 1 in Read more…
New NASA Data Blow Gaping Hole In Global Warming Alarmism
Image by AFP/Getty Images via @daylifeNASA satellite data from the years 2000 through 2011 show the Earth’s atmosphere is allowing far more heat to be released into space than alarmist computer models have predicted, reports a new study in the peer-reviewed science journal Remote Sensing. The study indicates far less future global warming will occur than United Nations computer models have predicted, and supports prior studies indicating increases in atmospheric carbon dioxide trap far less heat than alarmists have claimed.
Study co-author Dr. Roy Spencer, a principal research scientist at the University of Alabama in Huntsville and U.S. Science Team Leader for the Advanced Microwave Scanning Radiometer flying on NASA’s Aqua satellite, reports that real-world data from NASA’s Terra satellite contradict Read more…
Horn of Africa drought seen from space

Drought in Somalia, Kenya, Ethiopia and Djibouti is pushing tens of thousands of people from their homes as millions face food insecurity in a crisis visible from space. ESA’s SMOS satellite shows that the region’s soil is too dry to grow crops.
Somalis, who already face war in their country, have been fleeing to neighbouring countries in search of refuge. In Kenya’s Dadaab refugee camp, for example, over 1000 people – mostly children – arrive daily, severely dehydrated and malnourished.
While international aid agencies call this the ‘worst drought in decades,’ space technology has Read more…
DARPA’s advance research arm building virtual Internet to battle cyber attacks
The Pentagon’s advanced research branch is working on a virtual version of the Internet to further the U.S.’s resistance against cyber attacks. According to Reuters, the Defense Advanced Research Projects Agency, more commonly known as DARPA, is setting up something called the National Cyber Range. The National Cyber Range would be a virtual “testbed” to simulate a mini-Internet. Officials could use it to test virtual cyber-warfare games that experiment with different computer-generated-attack situations.
DARPA, the same agency that started that whole Internet thing in the 1960s, created the National Cyber Range project to make it simple to create different scenarios, combine those scenarios, and ultimately test any potential situations that may have to be dealt with on the real Internet. The purpose is to test things like network protocols as well as satellite and radio Read more…
Iran launches home-made satellite into orbit
Iran has launched a satellite into earth orbit in a feat that is likely to raise concerns among those who fear Iran’s intentions and nuclear development program.
“Our glorious scientists successfully put Iran’s first image-collecting satellite into orbit,” the TV report said.
Iran has made a series of claims about advances in its ambitious space program in recent years, which has Western powers worried about the possibility of its military applications.
Last year, Iran announced it had successfully launched a rocket carrying a mouse, turtle and worms into space.
Iran’s space program has expressed a goal of putting a man in orbit within 10 years, despite the Read more…
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…
Warm Water Causing Cold Winters
This map shows sea‑surface temperatures averaged over eight days in September 2001, as measured by NASA’s Terra satellite. Dark red represents warm water (32 degrees Celsius) and purple is cold (‑2 degrees Celsius). The Gulf Stream can be seen as the orange strip extending from the eastern U.S. toward the Atlantic.Imagine this: you are standing outside in New York City while waiting for a cab. It is in the winter and you are likely freezing. What if you were doing the same thing, but in Porto, Portugal?
Porto shares the same latitude at the Big Apple, but in Portugal you would be about 10 degrees warmer.
This happens for the northeastern coast of the U.S. and eastern coast of Canada. This is also true in other parts of the world. When the northeastern coast of Asia is colder, the Pacific Northwest is warmer.
Researchers at the California Institute of Technology have found an explanation. The culprit is warmer water off the eastern coasts of Read more…
The latest unsmoothed global sea level data from JASON shows a sharp downtick and slight downtrend
One of the great things about WUWT is that it attracts commenters with a wide range of skill sets, who can often contribute far and beyond what we even see from our government sources. I’ve lamented the lack of updates from the University of Colorado sea level website, and when I got no response to emails, I decided to make a rare phone call and ask why. The answer I got from Dr. R. Steven Nerem was:
“This new website design won’t work with our current format, so if you can just be patient and wait a couple of weeks we’ll have it online.”
Not content to wait, and prodded by another commenter in an online tussle, CA and WUWT regular Roman M decided to find out himself. The results speak for themselves, quite a drop in the latest JASON-1 datapoint, with a general slight downturn in the JASON1-2 data since late 2009:
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).
