“As a key partner in the mission, NASA provides the synthetic aperture radar, called VenSAR, to make high-resolution measurements of the planet’s surface features. On June 10, 2021, the European Space Agency (ESA) announced the selection of EnVision as …
“Europe’s Galileo satellite navigation constellation is set to grow. Later this year the first two out of 12 ‘Batch 3’ Galileo satellites will be launched by Soyuz from French Guiana. Their last step on the way to launch is …
“In November 2020, the Copernicus Sentinel-6 Michael Freilich satellite was launched into orbit from the Vandenberg Air Force Base in California, US. Now, months later, the satellite has successfully passed what is known as the ‘in-orbit verification phase’, where its …
“Candidate ‘green’ satellite propellants within a temperature-controlled incubator, undergoing heating as a way to simulate the speeding up of time. Today hydrazine is the most common propellant employed by thrusters aboard satellites: it is highly energetic in nature but also …
“This bendable space mirror can have its shape shifted to compensate for manufacturing or alignment errors within orbital telescopes or temperature-driven distortions. Very large space telescopes are necessary to increase image resolution and sensitivity, whether for deep space exoplanet detection …
“This highly compact beam forming network has been designed for multi-beam satellite payload antennas. Generating a total of 64 signal beams outputted from a single antenna, this novel design could cover the entire Earth with multiple spot beams from geostationary …
“A natural fibre that once wrapped early Egyptian mummies and was worn by Roman aristocrats has found a space-age purpose. Threading fibres from the flax plant through satellite panel material can help space missions burn up more rapidly during atmospheric …
“Monitoring the cryosphere is essential to fully assess, predict and adapt to climate variability and change. Given the importance of this fragile component of the Earth system, today ESA, along with Airbus Defence and Space and Thales Alenia Space, have …
“Europe’s Ariane 5 has delivered two telecom satellites Galaxy-30 and BSAT-4B, and the Mission Extension Vehicle (MEV-2), into their planned transfer orbits. There are also four notable updates to the launch vehicle. Arianespace announced liftoff at 23 …
“ESA’s cubic-metre-sized Proba-V minisatellite, seen left, has ended its seven-year global mission to monitor the daily growth of all Earth’s vegetation, a task being taken up by Copernicus Sentinel-3 instead, seen right. Proba-V was launched in 2013 to …
