New technique reveals changing shapes of magnetic noise in space and time
Tuesday, 27 December 2022 08:02
Electromagnetic noise poses a major problem for communications, prompting wireless carriers to invest heavily in technologies to overcome it. But for a team of scientists exploring the atomic realm, measuring tiny fluctuations in noise could hold the key to discovery.
"Noise is usually thought of as a nuisance, but physicists can learn many things by studying noise," said Nathalie de Leon, New study models the transmission of foreshock waves towards Earth
Tuesday, 27 December 2022 08:02
An international team of scientists led by Lucile Turc, an Academy Research Fellow at the University of Helsinki and supported by the International Space Science Institute in Bern has studied the propagation of electromagnetic waves in near-Earth space for three years. The team has studied the waves in the area where the solar wind collides with Earth's magnetic field called foreshock region, an Three time dimensions, one space dimension

How would our world be viewed by observers moving faster than light in a vacuum? Such a picture would be clearly different from what we encounter every day. We should expect to see not only phenomena that happen spontaneously, without a deterministic cause, but also particles traveling simultaneously along multiple paths - argue theorists from universities in Warsaw and Oxford.
Also the ve Virgin Orbit' Launcherone Systems given green light for upcoming mission
Tuesday, 27 December 2022 08:02
The U.K. Civil Aviation Authority has issued launch and range control licenses to Virgin Orbit (Nasdaq: VORB) to undertake the first satellite launch from UK soil. The granting of these licenses represents a major step forward for the historic Start Me Up mission, and reflects the CAA's concurrence that all reasonable steps have been taken by Virgin Orbit to ensure the desired safety, security, Inauguration of mainland Europe's first satellite launch complex

Christmas and winter spirit - also on Mars. Impact craters connected by a striped, coloured ribbon can be seen in the final and very wintry HRSC Mars image of this year. We wish all readers of our martian image series, published together with the European Space Agency (ESA) and Freie Universitat Berlin, happy holidays!

Video: Flight control, space weather and debris: What an astronaut needs to know
Friday, 23 December 2022 15:19
Recently, Andreas Mogensen, now getting ready for his "Huginn" mission to the ISS in 2023, stopped by ESA's ESOC mission control center in Darmstadt, Germany, to meet with some of the experts who keep our satellites flying.
Andreas usually works at NASA's Johnson Space Center in Houston as an ISS "capcom," and we don't often see him in Europe. A few months back, while returning to Germany for some training at ESA's Astronaut Center in Cologne, we seized the opportunity to ask him if he'd like to stop over in Darmstadt for a look behind the scenes at mission control, and he immediately answered, "yes!"
Andreas studied aeronautical engineering with a focus on "guidance, navigation and control of spacecraft" and we thought he'd be delighted to meet with the teams at mission control doing precisely that sort of work for our robotic missions.
We figured he'd also enjoy meeting colleagues from our Space Safety program, especially the ones working on space debris and space weather, as these are crucial areas that influence the daily life of astronauts on the ISS.

Russia’s unprovoked invasion of Ukraine was the biggest story of 2022. Aside from reviving Cold War fears of nuclear war and playing havoc with energy markets, it’s been a black swan event for a space industry still adjusting to a black swan called COVID.
