Two meteorological satellites, along with their ground application systems, have officially started operation, said the China Meteorological Administration on Thursday.
The trial operation of the two satellites, Fengyun-3E (FY-3E) and Fengyun-4B (FY-4B), began in June this year. They will provide observation data and application services to global users.

The technique referred to as "dynamical downscaling", which involves the use of regional climate models to dynamically infer the effects of large-scale climate processes at local scales, has proved to be an effective way to simulate precipitation at high resolution. Moreover, with advancements in supercomputing capabilities, dynamical downscaling is now progressing to the kilometer scale. ESA plasma sampler headed to the Moon and ISS

An innovative ESA-backed instrument to sample the space weather environment in-situ is set to join the International Space Station. Norway’s multi-Needle Langmuir Probe, m-NLP, due to be fitted to the European-made Bartolomeo platform on the ISS, a ‘front porch’ open to space, will map the ionospheric plasma surrounding the Station in unprecedented high resolution, performing almost 10 000 measurements per second continuously along its orbit.

Maybe we don't see aliens because they're waiting to hear a signal from us first
Tuesday, 06 December 2022 17:20 Write a comment
We've had a long-running series here at UT on potential solutions Fermi paradox—why aren't we able to detect any alien life out there in the Universe? But more possible solutions are being developed all the time. Now, another paper adds some additional theory to one of the more popular solutions—that aliens are just too busy to care about us.
The paper, released on arXiv, was written by Amri Wandel of the Racah Institute of Physics at the Hebrew University of Jerusalem. It makes two basic assumptions. First, aliens don't really care about planets with life on them. Second, they would care if they could detect intelligent life on one.
For the first assumption to be valid, it would help if the occurrence of "biotic" (i.e., having biology) planets is widespread. In that case, even advanced civilizations might not have enough resources to devote to fully exploring those planets, especially in the form of an actual probe.
Proposing a new idea for spacecraft propulsion that involves dynamic soaring
Tuesday, 06 December 2022 15:30 Write a comment
A team of researchers from McGill University and the Tau Zero Foundation is proposing a new idea for faster spacecraft propulsion that involves dynamic soaring. In their paper published in the journal Frontiers in Space Technology, the group outlines the idea of dynamic soaring as it applies to a speedy way to move through space and other possible uses for it.
Over the past several decades, as human-built space vehicles have made their way to many of the planets and moons in our solar system, it has become clear that a means is required for creating spacecraft that can get to distant destinations in space much faster.
