Antares roars into space

Antares Rocket Launches

NASA COMMERCIAL space partner Orbital Sciences Corporation launched its Antares rocket on Sunday from the new Mid-Atlantic Regional Spaceport Pad-0A at the agency’s Wallops Flight Facility in Virginia, USA.

The test flight was the first launch from the pad at Wallops and was the first flight of Antares, which delivered the equivalent mass of a spacecraft, a so-called mass simulated payload, into Earth orbit.

The test of the Antares launch system began with the rocket’s rollout and placement on the launch pad April 6, and culminated with the separation of the mass simulator payload from the rocket just minutes after launch.

Here’s the video of the launch – it goes for about 12 minutes:

The completed flight paves the way for a demonstration mission by Orbital to resupply the space station later this year. Antares will launch experiments and supplies to the orbiting laboratory carried aboard the company’s new Cygnus cargo spacecraft through NASA’s Commercial Resupply Services (CRS) contract.

Orbital is building and testing its Antares rocket and Cygnus spacecraft under NASA’s Commercial Orbital Transportation Services (COTS) program. After successful completion of a COTS demonstration mission to the station, Orbital will begin conducting eight planned cargo resupply flights to the orbiting laboratory through a US$1.9 billion NASA contract with the company.

“Today’s successful test marks another significant milestone in NASA’s plan to rely on American companies to launch supplies and astronauts to the International Space Station, bringing this important work back to the United States where it belongs,” said NASA Administrator Charles Bolden. “Congratulations to Orbital Sciences and the NASA team that worked alongside them for the picture-perfect launch of the Antares rocket. In addition to providing further evidence that our strategic space exploration plan is moving forward, this test also inaugurates America’s newest spaceport capable of launching to the space station, opening up additional opportunities for commercial and government users.

NASA’s Commercial Crew Program also is working with commercial space partners to develop capabilities to launch U.S. astronauts from American soil in the next few years.

New view of the Horsehead Nebula

ASTRONOMERS HAVE USED NASA’s Hubble Space Telescope and the European Space Agency’s (ESA) Herschel Space Observatory have produced stunning new photographs of the iconic Horsehead Nebula at infrared wavelengths.

Looking like an apparition rising from whitecaps of interstellar foam, the iconic Horsehead Nebula has graced astronomy books ever since its discovery more than a century ago. It is about 1,300 light-years from Earth.

The new far-infrared Herschel view shows in spectacular detail the scene playing out around the Horsehead Nebula at the right-hand side of the image, where it seems to surf like a ‘white horse’ in the waves of turbulent star-forming clouds.

It appears to be riding towards another favorite stopping point for astrophotographers: NGC 2024, also known as the Flame Nebula. This star-forming region appears obscured by dark dust lanes in visible light images, but blazes in full glory in the far-infrared Herschel view.

Intense radiation streaming away from newborn stars heats up the surrounding dust and gas, making it shine brightly to Herschel’s infrared-sensitive eyes.

The panoramic view also covers two prominent sites of massive star formation to the northeast (left-hand side of this image), known as NGC 2068 (or M78) and NGC 2071. These take on the appearance of beautifully patterned butterfly wings, with long tails of colder gas and dust streaming away.

Extensive networks of cool gas and dust weave throughout the scene in the form of red and yellow filaments, some of which may host newly forming lightweight stars.

The new Hubble view, taken at near-infrared wavelengths with its Wide Field Camera 3 to celebrate the 23rd anniversary of the launch of the observatory, zooms in on the Horsehead to reveal fine details of its structure.

Nearby stars illuminate the backlit wisps along the upper ridge of the nebula in an ethereal glow. The harsh ultraviolet glare from these bright stars is slowly evaporating the dusty stellar nursery. Two fledgling stars have already been exposed from their protective cocoons, and can just be seen peeking out from the upper ridge.

The nebula is a favourite target for amateur and professional astronomers. It is shadowy in optical light, but appears transparent and ethereal when seen at infrared wavelengths.
