NASA contacts Voyager 2 using upgraded Deep Space Network dish

On Oct. 29, mission operators sent a series of commands to NASA's Voyager 2 spacecraft for the first time since mid-March. The spacecraft has been flying solo while the 70-meter-wide (230-foot-wide) radio antenna used to ...

Infrared light antenna powers molecular motor

Light-controlled molecular motors can be used to create functional materials to provide autonomous motion, or in systems that can respond on command. For biological applications, this requires the motors to be driven by low-energy, ...

Flood risks: More accurate data due to COVID-19

Emerging use of Global Navigation Satellite System (GNSS) makes it possible to continuously measure shallow changes in elevation of Earth surface. A study by the University of Bonn now shows that the quality of these measurements ...

Image: Mesh reflector for shaped radio beams

This prototype 2.6-m diameter metal-mesh antenna reflector represents a big step forward for the European space sector: versions can be manufactured to reproduce any surface pattern that antenna designers wish, something ...

SAMURAI measures 5G communications channels precisely

Engineers at the National Institute of Standards and Technology (NIST) have developed a flexible, portable measurement system to support design and repeatable laboratory testing of fifth-generation (5G) wireless communications ...

Image: Place for space testing

ESA's Compact Antenna Test Range at its ESTEC technical centre in Noordwijk, the Netherlands. This anechoic chamber is used to test space antennas of 1 m across or less, or else entire small satellites.

Nanosatellite with global mission tested for space

ESA's largest antenna test facility remains operational despite the COVID-19 pandemic, performing pre-flight testing for the latest satellite in a constellation to serve the internet of things.

Video: Views of Earth from BepiColombo's flyby

A compilation of about 200 images collected by the joint European-Japanese mission BepiColombo during its first—and only—flyby of Earth on 10 April 2020, a manoeuvre needed to adjust its trajectory en route to its destination, ...
