"Alien" Particles Found Invading Our Solar System—A First. For the first time, a NASA spacecraft has directly observed "alien" particles that came from beyond our solar system, astronomers announced today. The discovery not only gives us a glimpse of what exists in the so-called interstellar medium—the matter between stars—but also offers clues to the anatomy of our local galactic neighborhood. Orbiting Earth some 200,000 miles (322,000 kilometers) away, the Interstellar Boundary Explorer (IBEX) spacecraft was able to snag samples of hydrogen, oxygen, and neon that came from interstellar space. "It's exciting to be able to have these first observations of alien matter—stuff that didn't come from our sun or the planets, but came from the outside of our solar system, from other parts of the galaxy," David McComas, team leader for the IBEX program, said during a NASA news conference Tuesday.

Astronauts May Evacuate Space Station in November, NASA Says

EDT. The International Space Station may have to start operating without a crew in November if Russian engineers don't figure out soon what caused a recent rocket failure, NASA officials announced today (Aug. 29). The unmanned Russian cargo ship Progress 44 crashed just after its Aug. 24 launch to deliver 2.9 tons of supplies to the orbiting lab. The failure was caused by a problem with the Progress' Soyuz rocket, which is similar to the one Russia uses to launch its crew-carrying vehicle — also called Soyuz — to the station.

Currently, six astronauts reside on the space station. But three of these astronauts are due to return to Earth next month, and the rest are scheduled to come back in mid-November. 9/8/11: The GRAIL, Twin Spacecraft Launches for the Moon... 3-day GOES X-ray Flux Monitor.

Huge Defunct Satellite to Plunge to Earth Soon, NASA Says

Heads up! That's the word from NASA today (Sept. 7) given the impending re-entry of a 6.5-ton satellite through Earth's atmosphere. The huge Upper Atmosphere Research Satellite (UARS) is expected to re-enter Earth's atmosphere in an uncontrolled fall in late September or early October. Hawaiian Mystery Halo Bubble Solved - It Was a Minuteman Missile‬‏ Pax Americana and the Weaponization of Space. Star Wars is no longer science fiction.

Pax Americana and the Weaponization of Space

The prospect of Earth being ruled from space is no longer science-fiction. The dream of the original Dr. Strangelove, Wernher von Braun (from Nazi rocket-scientist to NASA director) has survived every US administration since WW2 and is coming to life. Today the technology exists to weaponize space, a massive American industry thrives, and nations are maneuvering for advantage. Pax Americana tackles this pivotal moment. With startling archival footage and unprecedented access to US Air Force Space Command, this elegant, forceful documentary reveals the state of play through generals, space-policy analysts, politicians, diplomats, peace activists, and hawks.

LRO Showing Us the Moon as Never Before

This rich new portrait has been rendered by LRO's seven onboard instruments, which together have delivered more than 192 terabytes of data, images and maps - the equivalent of nearly 41,000 typical DVDs. "This is a tremendous accomplishment," says Douglas Cooke, Associate Administrator of the Exploration Systems Mission Directorate at NASA Headquarters, Washington. "The exploration phase of the mission delivered a lot more than it originally promised, and that's been just the beginning for LRO. " The primary objective of the mission was to enable safe and effective exploration of the moon.

A researcher at the Harvard-Smithsonian Center for Astrophysics believes that a new kind of supernova is at work in recent observations of bright but short-lasting stellar explosions that don’t appear to fit known categories.

A supernova that's super different

Hagai Perets began working on the problem after coming across a description of a 2002 supernova, discovered by University of California, Berkeley, researchers, whose description didn’t seem to fit into known categories. Instead of forgetting about it, he dove into past literature, looking for similar supernovas with unexplained characteristics.
