In the first act of lunar exploration, Neil Armstrong and Buzz Aldrin were major characters. In setting its sights on the Moon, ESA hopes to bring many more actors to this off-world stage. By testing the market for transport services to the Moon, ESA aims to push the limits of technology and create new models of space business. Touching down on the Moon was a monumental moment in human history. Eight short years and enormous resources took humankind to the lunar surface, initially for le...

Astronomers have used ALMA to capture a strikingly beautiful view of a delicate bubble of expelled material around the exotic red star U Antliae. These observations will help astronomers to better understand how stars evolve during the later stages of their life-cycles. In the faint southern constellation of Antlia (The Air Pump) the careful observer with binoculars will spot a very red star, which varies slightly in brightness from week to week. This very unusual star is called U Antliae and...

The Sun's recent activity has caught the interest of scientists and space weather forecasters worldwide, highlighting the need to keep a watchful eye on our star and its awesome power. On 6 and 10 September, our Sun produced a pair of solar flares, the strongest observed in over 10 years. They were accompanied by huge eruptions of billions of tonnes of matter into space. While many such eruptions fall back onto the hot surface, these two did not and became 'coronal mass ejections' (CMEs) -...

NASA's Hubble Space Telescope has observed a planet outside our solar system that looks as black as fresh asphalt because it eats light rather than reflecting it back into space. This light-eating prowess is due to the planet's unique capability to trap at least 94 percent of the visible starlight falling into its atmosphere. The oddball exoplanet, called WASP-12b, is one of a class of so-called "hot Jupiters," gigantic, gaseous planets that orbit very close to their host ...

Launch is the most strenuous part of a satellite's life. To survive the extreme sound wave pressure and pounding vibrations generated by more than 700,000 lbs. of thundering rocket thrust, spacecraft need a solid, reliable design if they hope to arrive operational on orbit. On July 13, Lockheed Martin (LMT)'s second, fully-assembled GPS III space vehicle (SV) completed a realistic simulation of its future launch experience and passed this critical acoustic environmental test with flying color...
