The European Space Agency (ESA) has provided more evidence that suggests the surface of Mars was once home to an ocean. Featuring ground-penetrating radar capabilities, the MARSIS (Mars Advanced Radar for Subsurface and Ionosphere Sounding) radar aboard the ESA’s Mars Express spacecraft has detected sediments like that seen on an ocean floor.

European Space Agency selects first two "Cosmic Vision" missions

The European Space Agency (ESA) this week announced the first two missions selected for its Cosmic Vision 2015-2025 Plan. The first, known as Solar Orbiter, will see a spacecraft operating closer to the Sun than any previous mission with a particular focus on examining the solar wind. The second, Euclid, is essentially a space telescope whose primary goal is to study the accelerating expansion of the universe in an attempt to provide an understanding of the exact nature of dark matter.

Waterproof fabric anntena could save people lost at sea

A patch about the size of the leather name tab on a pair of jeans could save your life one day – should you be stranded at sea, that is. In a project overseen by the European Space Agency (ESA), researchers from Finnish company Patria and the Tampere University of Technology have created a flexible fabric antenna, that can be sewn into life vests. Once activated, that antenna transmits its coordinates to earth-orbiting satellites, that can immediately relay the location to rescue personnel. Read More
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
ESA review finds 'no impediments' for SKYLON spaceplane development

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.

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.

GPS satellites tell us where we are, but what tells them where they are?

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?
