LOS ANGELES Adidas Ultra Boost Grey Sale , July 1 (Xinhua) -- The planned launch of a U.S. rocket carrying a CO2 monitoring satellite from California was called off just before liftoff on Tuesday due to a failure in the launch pad water flow, a live NASA TV broadcast showed.
The United Launch Alliance Delta 2 rocket carrying the Orbiting Carbon Observatory-2 (OCO-2) spacecraft, the first dedicated NASA mission to monitor atmospheric carbon dioxide on global scales, was supposed to be launched from the Vandenberg Air Force Base in California at 2:56 a.m. PDT Tuesday (0956 GMT).
But the launch was canceled when a failure in a Vandenberg Air Force Base Space Launch Complex 2 pad water system was discovered. The system provides sound suppression to dampen acoustic waves at liftoff and protects a launch pad flame duct.
The countdown was halted at T-46 seconds. Since the launch window was only 30 seconds, mission controllers did not have time to analyze the issue and get the rocket back on track for launch Tuesday morning.
OCO-2 has only a 30-second launch window each day. The launch window is short because the spacecraft needs to be precisely aligned within a series of Earth-observing satellites known as the "A-Train."
"It's a bit of a disappointment for the launch team when you have a great countdown up to that point," Tim Dunn Adidas Ultra Boost Triple Black Sale , NASA launch controller said during the NASA TV broadcast.
Managers and engineers were assessing the issue to determine the cause of the failure and when they can attempt to launch OCO-2.
The OCO-2 spacecraft is on external power and the Delta II rocket first stage liquid oxygen is being offloaded. Both the spacecraft and rocket are in a safe configuration, NASA said.
The mission marks NASA's second try to measure atmospheric carbon dioxide from space. In 2009, the space agency launched the origin OCO satellite aboard a Taurus XL rocket. Shortly after liftoff, the rocket crashed into the ocean off Antarctica.
OCO-2 is dedicated to studying atmospheric carbon dioxide, the leading human-produced greenhouse gas driving changes in Earth's climate.
According to NASA, before the Industrial Revolution Adidas Ultra Boost Black Sale , there were about 280 molecules of carbon dioxide out of every million molecules in the atmosphere, that is, 280 parts per million.
By 2014, at approximately 400 parts per million, atmospheric carbon dioxide is now at its highest level in the past 800,000 years.
The burning of fossil fuels and other human activities are currently adding nearly 40 billion tons of carbon dioxide to the atmosphere each year Adidas Ultra Boost Triple White Sale , producing an unprecedented buildup in this greenhouse gas.

NAIROBI, June 22 (Xinhua) -- Two days after winning the Africa Nation Championships, Kenya team is heading to Monterrey, Mexico for the volleyball World Grand Prix for preliminary round matches.
Evan Wasike, Kenya Volleyball Federation (KVF) Secretary General, confirmed Monday that the team will leave the country on Tuesday for Mexico.
"The players are not breaking camp. They leave tomorrow for the World Grand Prix Adidas Ultra Boost White Sale ," said Wasike in Nairobi. "Kenya will start with Mexico (26-28 June), then Algeria (July 2-5 ). If the Kenya team qualifies after Mexico and Algeria, they will then go to Australia (July 7-10)."
Kenya beat Algeria 3-0 (25-17, 25-21, 25-20) to claim their ninth Africa volleyball crown. Both finalists Kenya and Algeria already secured the two African tickets for 2015 FIVB World Cup to be staged in Japan Aug. 22 to Sept. 6.
However, Kenya coach David Lung'aho will have to test the waters ahead of the World Cup when his team tours Mexico and Algeria for the World Grand Prix.
Kenya team has only three foreign-based players Adidas Ultra Boost Sale , captain Brackcides Agala and setter Jane Wacu, both with French side, Chamalieres, and left attacker Mercy Moim, who plays in Finland.
The 23rd edition of the FIVB Volleyball World Grand Prix, which is the International Volleyball Federation's (FIVB) premier annual competition for women's national teams Ultra Boost Grey Sale , will run from June 26 to August 1.
The 2014 edition of the World Grand Prix, which featured 28 participating countries for the first time, saw Brazil triumph for a record 10th time after winning against Japan in the final match of the competition. Russia claimed bronze, their first World Grand Prix medal for five years.
The FIVB World Grand Prix has grown spectacularly since its first edition in 1993, when it featured just eight teams. The increase in the number of participating teams brings with it an increased level of competition and has also helped to spread the World Grand Prix to new territories around the world.
One of China's top scientists responded to criticism of an award-winning project, saying that the adoption of open source codes was "legal and reasonable".
Zhang Yaoxue Ultra Boost Triple Black Sale , a computer scientist at the Chinese Academy of Engineering who led a team that won this year's top State Natural Sciences Award for inventing the concept of transparent computing, said that the project did not adopt the source code.
However, Zhang, who is also president of Central South University and a professor with Tsinghua University, said another ongoing project, transparent desk Ultra Boost Black Sale , adopted the source code but it was abiding by the general public license.
According to the research team, transparent computing refers to programming in which users are not aware of the software and yet can access and accomplish tasks from any type of device.
Over the past 16 years, the top science award, which recognizes major breakthroughs in fundamental research, has only been handed out six times.
However, Zhang's win triggered debate online Ultra Boost Triple White Sale , with some comments suggesting that the project was undeserving.
On Monday, a netizen with the Web name KraneSun on GitHub, a web-based software repository hosting service, accused Zhang of copying a source code.
