Satellites are incredible feats of engineering, and the antennas aboard them are one of their most complex systems which makes producing and testing...

The satellite will launch next year to gauge forest biomass, giving us a better shot at understanding how much carbon dioxide Earth’s trees are absorbing.

Manufacturing Bits: May 4 Measuring Moon dust The National Institute of Standards and Technology (NIST) and others have developed a new way to study and measure moon dust. Using an X-ray nano computed tomography (XCT) technique, researchers measured the 3D shapes of lunar particles as small as 400nm in length. The goal is to find out how these shapes impact the optical scattering characteristics of lunar dust on the Moon. These measurements could provide more insights in terms of the Moon and its color and brightness. “This in turn might help improve tracking of weather patterns and other p...

Hot and cold space radio testing Details Related ESA’s newest radio-frequency test facility allows direct measurement of antenna systems in the very vacuum conditions and thermal extremes they will work in, including the chill of deep space. It will soon be put to work testing the Juice mission’s radiometer – destined to probe the thin atmospheres of Jupiter’s largest moons. The recently completed facility is called the Low-temperature Near-field Terahertz Chamber , or Lorentz. Based at ESTEC in the Netherlands, it can test high-frequency RF systems such as stand-alone antennas and c...

Arrival of world-first test facility Details Related ESA’s ESTEC technology centre in Noordwijk, the Netherlands, took delivery of this 2.8m-diameter vacuum chamber to host ESA’s latest world-first test facility. The Dutch Terahertz company in Groningen led the wide portfolio of mostly Dutch suppliers and companies that manufactured the 5–tonne stainless steel chamber. It was delivered to ESTEC last September. “Since then we’ve been working flat out to integrate our new Lorentz facility, trouble shoot and test it,” comments antenna engineer Paul Moseley. “The project took plac...
