An Antares launch vehicle boosts the Orbital Sciences Cygnus spacecraft on it's way to the...

Orbital Sciences Corporation today successfully launched the first of eight Cygnus cargo supply missions to the International Space Station (ISS). Orbital's Antares medium-lift rocket (originally called the Taurus II) carried the Cygnus into an initial orbit of 135 x 175 miles (220 x 280 km), inclined at 51.6 degrees relative to the equator. The Cygnus is flying solo now, with full communications and deployed solar arrays, carrying roughly 2,800 lb (1,300 kg) of cargo toward a January 12 rendezvous and docking with the ISS.  Read More

Earth saw in the New Year with some celestial fireworks as the first asteroid to be discovered this year, 2014AA, likely impacted the Earth between 7 pm Wednesday and 2 pm Thursday GMT.  Read More

The Space Surveillance Telescope (SST) is designed to track space debris and small objects

In order to dodge something, you need to see it. If that something is space debris then sometimes the best thing to use is an old-fashioned telescope – or, in the case of the US Department of Defense, a state-of-the-art telescope capable of searching an area larger than the United States in seconds. That’s why DARPA is preparing to deliver the new Space Surveillance Telescope (SST) to Western Australia, where it will help track small satellites and space debris orbiting the Earth when it becomes operational in 2016.  Read More

We are continually being surprised by new discoveries of near-Earth asteroids and comets, often noticing them only after they have completed a close approach. Only one asteroid has ever been found and projected to impact prior to its actually doing so. With that in mind, NASA, Planetary Resources, and Zooniverse have formed a collaboration to use citizen scientists to detect members of the vast swarm of near-Earth objects not yet recognized or mapped.  Read More

ESA announced on Monday that its Gravity field and steady-state Ocean Circulation Explorer (GOCE) has ended its extended mission to map the Earth’s gravitational field. Orbiting the Earth at an altitude of 224 km (139 mi), the unmanned probe, known as the “Ferrari of space” because of its streamlined shape, has run out of fuel for the ion engine that kept it in orbit and is expected to reenter the Earth’s atmosphere within two weeks.  Read More

Artist's concept of the LADEE spacecraft (Image: NASA)

Space communications have relied on radio since the first Sputnik in 1957. It’s a mature, reliable technology, but it’s reaching its limits. The amount of data sent has increased exponentially for decades and NASA expects the trend to continue. The current communications systems are reaching their limits, so NASA and ESA are going beyond radio as a solution. As part of this effort, ESA has finished tests of part of a new communications system, in preparations for a demonstration in October in which it will receive a laser data download from a NASA lunar orbiter.  Read More

Artist's concept for a slingatron space launcher to hurl payloads into space

People have been shooting things into space since the 1940s, but in every case this has involved using rockets. This works, but it’s incredibly expensive with the cheapest launch costs hovering around US$2,000 per pound. This is in part because almost every bit of the rocket is either destroyed or rendered unusable once it has put the payload into orbit. Reusable launch vehicles like the SpaceX Grasshopper offer one way to bring costs down, but another approach is to dump the rockets altogether and hurl payloads into orbit. That's what HyperV Technologies Corp. of Chantilly, Virginia is hoping to achieve with a “mechanical hypervelocity mass accelerator” called the slingatron.  Read More

If you have ever wished you could experience weightlessness but cant afford space tourism, then a Dusseldorf art gallery may get you closer, as long as you wear sturdy shoes. The "in-orbit" multi-level art installation by Tomás Saraceno is suspended 20m (60 ft) above the piazza of the Kunstsammlung Nordrhein-Westfalen gallery. The Argentinian architect and artist’s largest work to date aims to resemble a cloud landscape for those brave enough to walk through it.  Read More

To paraphrase an old saying, if the astronaut can’t go to the asteroid, the the asteroid must come to the astronaut. In a study released by the Keck Institute for Space Studies, researchers outlined a mission to tow an asteroid into lunar orbit by 2025 using ion propulsion and a really big bag. The idea is to bring an asteroid close to Earth for easy study and visits by astronauts without the hazards and expense of a deep space mission.  Read More
