July 11, 2023 Researchers have tested the software of three satellites. And they found many standard security mechanisms ...
June 15, 2023 Extreme space weather threatens vital satellites orbiting the Earth, including the Global Navigation Satellite Systems (GNSS) which pass through the heart of the outer radiation belt. New research ...
Feb. 21, 2023 On-chip distributed radiation sensors and current-sharing techniques can be used to reduce the impact of radiation on the radio and power consumption of small satellites, respectively. New findings ...
Jan. 23, 2023 Space weather can interfere with spaceflight and the operation of satellites, but the phenomenon is very difficult to study on Earth because of the difference in gravity. Researchers effectively ...
Dec. 20, 2022 ESA's novel Aeolus satellite reliably measures wind speed also in higher air layers and thus in a region of the atmosphere where other direct global wind measurements are relatively sparse. This is ...
Sep. 14, 2022 Researchers present the most precise test yet of the weak equivalence principle, a key component of the theory of general relativity. The report ...
Aug. 18, 2022 Researchers report an experimental demonstration of a space-to-ground quantum key distribution (QKD) network using a compact QKD terminal aboard the ...
July 15, 2022 Changes in atmospheric density after sunset can cause hot pockets of gas called 'plasma bubbles' to form over the Earth's equator, resulting in communication disruptions between satellites and the ...
June 17, 2022 The European Gaia space mission has produced an unprecedented amount of new, improved, and detailed data for almost two billion objects in the Milky Way galaxy and the surrounding cosmos. The Gaia ...
Feb. 2, 2022 Geospatial scientists have found a way to detect plastic waste on remote beaches that are not visible in conventional satellite images, bringing us ...
