Google Ocean: Atlantis turns out to be boat mapping lines

Keen observers had spotted what appeared to be the outline of a vast city on the floor of the Atlantic Ocean. But the criss-crossing lines, located 600 miles west of the Canary Islands, were today explained by Google as sonar data collected as boats mapped the ocean floor.
A spokeswoman said: "It's true that many amazing discoveries have been made in Google Earth including a pristine forest in Mozambique that is home to previously unknown species and the remains of an Ancient Roman villa.
Jets and rockets will be combined in a powerfull Spacecraft

ESA is planning big for the next decade, its recent actions show. It envisions and supports the construction of a groundbreaking project meant to yield a spacecraft capable of behaving both as a jet airplane and as a rocket. Basically, the new system will be capable of lift-of from an airfield, deliver up to 12 tonnes of cargo into orbit, and then return to land on the same runway. Such an innovation would forever change the nature of spaceflight as we know it, and would open the gates of development for this $150 billion-per-year industry.

NASA Image Of The Day

| Snapshot of the International Space Station | ||
| On March 13, 2008, the International Space Station passed across the field-of-view of Germany's remote sensing satellite, TerraSAR-X, at a distance of 195 kilometers, or 122 miles, and at a relative speed of 34,540 kilometers per hour, or more than 22,000 mph. In contrast to optical cameras, radar does not 'see' surfaces. Instead, it is much more aware of the edges and corners which bounce back the microwave signal it transmits. Smooth surfaces such as those on the station's solar generators or the radiator panels used to dissipate excess heat, unless directly facing the radar antenna, tend to deflect rather than reflect the radar beam, causing these features to appear on the radar image as dark areas. The radar image of the station therefore looks like a dense collection of bright spots from which the outlines of the space station can be clearly identified. The central element on the station, to which all the modules are docked, has a grid structure that presents a multiplicity of reflecting surfaces to the radar beam, making it readily identifiable. This image has a resolution of about one meter (about 39 inches). In other words, objects can be depicted as discrete units--that is, shown separately--provided that they are at least one meter apart. If they are closer together than that, they tend to merge into a single block on a radar image. Since this image was taken, the station has expanded and is more than 90 percent complete, including a full complement of solar arrays. Image Credit: DLR... | ||
