Following an open invitation to tender, the technology multinational GMV, European industrial leader in Space Situational Awareness (SSA) and Space Surveillance and Tracking (SST), has been awarded a new contract by the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT), located in Darmstadt (Germany) for the provision of Operational Optical Data Services to suppo The abyssal world: the last terra incognita of the Earth surface

The deep-ocean floor is the least explored ecosystem on the planet, despite covering more than 60% of the Earth surface. Largely unknown life in abyssal sediments, from benthic animals to microbes, helps to recycle and/or sequester the sinking (in)organic matter originating from pelagic communities that are numerically dominated by microscopic plankton.
Benthic ecosystems thus underpin two A new programming language for high-performance computers

High-performance computing is needed for an ever-growing number of tasks - such as image processing or various deep learning applications on neural nets - where one must plow through immense piles of data, and do so reasonably quickly, or else it could take ridiculous amounts of time. It's widely believed that, in carrying out operations of this sort, there are unavoidable trade-offs between spe NASA outlines concerns about Starlink next-generation constellation in FCC letter

NASA says that SpaceX’s proposal for a second-generation Starlink constellation with 30,000 satellites could lead to a “significant increase” in potential collisions in low Earth orbit and interfere with the agency’s launches and scientific activities.

Dozens of SpaceX internet satellites lost to geomagnetic storm
Wednesday, 09 February 2022 20:51 Write a comment
Up to 40 SpaceX high-speed internet satellites have been knocked out of orbit by a geomagnetic storm shortly after launch, but pose little threat to Earth as they burn up in the atmosphere, the company said.
Geomagnetic storms are caused by ejections of the solar corona into space, resulting in disturbances to the Earth's upper atmosphere and increased drag on objects in low orbits.

Watch ESA astronaut Matthias Maurer exchange a sample in the Materials Science Laboratory (MSL) on the International Space Station.
The sample is for an experiment called MICAST that aims to deepen our understanding of the physical principles that govern solidification processes in metal alloys. This knowledge could help improve casting processes on Earth, leading to the development of new lightweight, high-performance materials for future spacecraft and innovation.
Matthias is spending approximately six months aboard the Space Station for his ESA mission Cosmic Kiss. During this time, he will support around 36 European and many more international experiments in orbit.

Up to 80% of the Starlink satellites launched by SpaceX last week will soon reenter, or have already done so, because a geomagnetic storm kept the spacecraft from raising their orbits.
