In bad news for NASA (and the planet in general), the Orbiting Carbon Observatory (OCO) satellite did not reach orbit as planned yesterday. According to a launch contingency briefing from NASA, the Taurus XL from California's Vandenberg Air Force Base at 4:55 a.m. EST proceeded normally, with only typical "minor issues" reported as the rocket approached lift-off, but preliminary indications are that the fairing on the Taurus XL launch vehicle failed to separate.  Read More

When we are born, we soil ourselves and other people clean it up for us. As we mature, we take responsibility for our own excrement. Strangely, as a society, we're not at all good at toilet training ourselves regarding the excrement produced by industry, transport or agriculture. Human beings capacity to eschew short term gain when faced with long term harm is notoriously woeful so it’s not surprising we've done exactly the same thing in space, leaving so much debris that it's now dangerous to be in the orbital band around earth due to the likelihood of being hit by junk traveling at 18,000 mph. The latest evidence: last week saw the first ever accidental collision between two intact spacecraft, a deactivated Russian satellite and an Iridium 33 satellite, which left a fresh cloud of debris 497 miles above the Earth.  Read More

NASA’s Orbiting Carbon Observatory spacecraft and its Taurus XL launch vehicle are undergoing preparations for liftoff on February 23. The Orbiting Carbon Observatory’s mission is to collect precise global measurements of carbon dioxide (CO2) in the Earth's atmosphere to improve our understanding of the natural processes and human activities that regulate the abundance and distribution of this important greenhouse gas - important because its the leading human-produced greenhouse gas driving changes in Earth's climate. This improved understanding will enable more reliable forecasts of future changes in the abundance and distribution of CO2 in the atmosphere and the effect that these changes may have on the Earth's climate.  Read More

Anyone not familiar with Google’s virtual globe program Google Earth would have to have been living on another planet – maybe Mars. But a new initiative by Google and NASA might pique even Martian interest with the advent of a Mars mode in Google Earth 5. Google Mars 3D brings the red, red hills of home to any Earth bound Martian’s desktop and enables users to fly virtually through enormous canyons and scale huge mountains on Mars, higher than any found on Earth.  Read More

NASA's two STEREO spacecraft, launched on October 25, 2006, will align on either side of the sun on February 6, 2011, allowing scientists to view the entire sun simultaneously for the first time in history. The Solar TErrestrial RElations Observatory is currently providing scientists with a view of 75% of the sun.  Read More

Until November, Tristan da Cunha was home only to 271 people, a small flightless bird, and a piece of land named Inaccessible Island. Now the world's most remote inhabited archipelago is host to a Danish Observatory designed to help improve our understanding the Earth’s weakening magnetic field and the way this affects satellites.  Read More

Dusting off an old renewable energy proposal, president of the National Space Society Ben Bova recently published an article in The Washington Post calling for the next president of the United States to commission a US$1 billion solar power satellite from NASA before the end of their second term. The satellite would harness energy directly from the sun and broadcast it back to a receiver on Earth using microwave frequencies.  Read More

The Indian Space Research Organisation has successfully launched Chandrayaan-1, the country’s first scientific mission to the moon. The two-year, USD$80 million mission will see the PSLV-C11 rocket enter lunar orbit in roughly two weeks, before descending to a final 100 km-high circular orbit. The Moon Impact Probe will land on the lunar surface, while the orbiter will continue gathering data with 11 scientific instruments.  Read More

NASA has launched the Interstellar Boundary Explorer, which will observe the edge of our solar system from a 200,000-mile Earth orbit and determine whether or not we’re... err, doomed. Over the next two years, the 23-inch high octagonal craft will study the area of space where solar wind hits the wider galaxy – hopefully it will also find out why the solar wind, which shields us from harmful cosmic rays, has decreased by 25% in the last ten years.  Read More
