At approximately one billion pixels, it’s the largest digital camera ever built for a space mission. Over a five-year period, the “billion-pixel array” will be used aboard the European Space Agency’s Gaia spacecraft, to map upwards of a billion stars. While it will be focusing mainly on our own Milky Way galaxy, Gaia will also be mapping other celestial bodies, including galaxies and quasars near the edge of the observable universe.  Read More

After nearly 30 years of service, the Space Shuttle fleet is due to enter retirement with the last ever mission scheduled for takeoff on July 8, 2011. In its lifetime, the world’s first Reusable Launch Vehicle (RLV) has provided information that will prove invaluable for the next generation of spacecraft that will succeed it. One such craft is the Skylon, an unpiloted, single-stage, reusable spaceplane currently under development by UK-based Reaction Engines Ltd. (REL). The Skylon got a shot in the arm last month with the release of a technical review of Skylon carried out by the European Space Agency (ESA) that concluded there are “no impediments” that would prevent the continued development of the Skylon and its SABRE engine.  Read More

An unexpected measurement has been achieved with the Venus Express, a satellite currently studying the atmosphere of Venus. While the satellite was not fitted with instruments to directly measure atmosphere density, the scientists have discovered by measuring the drag as the Venus Express experiences air resistance that the atmosphere is 60 percent thinner than expected. This "working on the fly" approach could allow the scientists to extend the life of the craft allowing them to collect more data.  Read More

The first joint mission between the European Space Agency (ESA) and NASA that will study the chemical makeup of the martian atmosphere is scheduled for 2016. The ExoMars Trace Gas Orbiter marks an unprecedented alliance between the two agencies for future ventures to Mars and is the first in a planned series of joint missions leading to the return of a sample from the surface of the Red Planet. Scientists worldwide were invited to propose the spacecraft’s instruments and the ESA and NASA have now made their selections.  Read More

The Ducati team set itself a very ambitious goal when it went about re-imagining its least popular model, the Multistrada adventure bike. The aim was to make the 2010 Multistrada a much more flexible bike than anything before it, offering proper sportsbike performance, true long-range touring abilities, easy commuting and a genuine ability to get offroad and play in the dirt. Starting with the monstrous v-twin from the 1198 superbike, the design team has pulled together and integrated a huge range of cutting-edge technologies to get there. In fact, with its traction control, variable engine maps and electronically adjustable Ohlins suspension, there's a good argument to say that it'll be the most technologically advanced motorcycle in production next year. Oh, and it'll be much, much lighter and much, much more powerful than anything else in the adventure bike world. Forget everything you know about Multistradas, this bike is going to be an absolute animal.  Read More

The 658kg (1,450 lb) Soil Moisture and Ocean Salinity (SMOS) satellite launched by the European Space Agency (ESA) this week is the first ever satellite designed both to map sea surface salinity and to monitor soil moisture on a global scale. The unique radiometer it carries will enable passive surveying of the water cycle between oceans, the atmosphere and land thereby playing a key role in the monitoring of global climate change.  Read More

Global Positioning System (GPS) devices have permeated society to the point where millions of us rely on them daily for directions, locations and traffic avoidance (if only they could tell me where I left my car keys). GPS satellites send signals to a receiver in your handheld or car-based GPS navigator, which calculates your position on the planet based on the location of the satellites and your distance from them. The distance is determined by how long it took the signals from various satellites to reach your receiver. But have you ever thought what tells the GPS satellites where they are in the first place?  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

August 30, 2008 The global warming debate will get even hotter in the near future with the news that current observations from ESA's Envisat satellite suggest that the extent of Arctic polar sea-ice may this year shrink to a level very close to that of last year's record minimum ice cover. Envisat observations from mid-August depict that a new record of low sea-ice coverage could be reached in a matter of weeks. This animation is a series of mosaics of the Arctic Ocean created from images acquired between early June and mid-August 2008 from the Advanced Synthetic Aperture Radar (ASAR) instrument aboard Envisat. The dark grey colour represents ice-free areas while blue represents areas covered with sea ice. The image at right shows sea-ice coverage as of mid-August 2008 with the red line indicating the all-time minimum Arctic sea-ice coverage in September 2007. Anyone know of any DIY Ark-building courses?  Read More
