... been extensively studied across many wavelengths of light, from gamma waves down to radio waves. In fact it was a beam of radio wave emission in 1931 that first drew astronomers attention to the invisible void that sits in the...
... downlinks have now become popular. However, not only must the onboard laser need to point its beam with sufficient accuracy and precision so that the target can receive as many photons as possible into the...
Saturn’s Moon Titan captured the imagination of enthusiasts everywhere when Cassini and the Huygens probe beamed back pictures of a world littered with mountains and lakes due to its active methane-based hydrologic cycle. ...
...to alter or tilt its orbit. Data gathered by Solar Orbiter will be stored on the spacecraft, then ‘downlinked’ (or beamed) to Earth during eight-hour communication windows, via the 35 metre Malargüe ground station in Argentina. Ground stations in ...
