Each year, strong winds carry more than a billion metric tons - or the weight of 10,000 aircraft carriers - of mineral dust from Earth's deserts and other dry regions through the atmosphere. While scientists know that the dust affects the environment and climate, they don't have enough data to determine, in detail, what those effects are or may be in the future - at least not yet.

Scientist reviews the key technologies for space-based situational awareness
Thursday, 14 July 2022 16:54
Since the launch of the first man-made earth satellite, the number of space objects has been rapidly increasing. According to the authoritative statistics from NASA, over 6,400 orbiting spacecraft still existed until early 2021. Furthermore, the total number of rocket debris above 10 cm has exceeded 16,000. The space environment has become highly congested due to the increasing space debris, seriously threatening the safety of orbiting spacecraft.
Space-based situational awareness, as a comprehensive capability of threat knowledge, analysis, and decision-making, is of significance to ensure space security and maintain normal order. Various space situational awareness systems have been designed and launched. Data acquisition, target recognition, and monitoring constituting key technologies make major contributions, and various advanced algorithms are explored as technical supports.
However, comprehensive reviews of these technologies and specific algorithms rarely emerge. This disadvantages the future development of space situational awareness. In a review paper recently published in Space: Science & Technology, Shuang Li from College of Astronautics, Nanjing University of Aeronautics and Astronautics, reviewed and analyzed research advancements in key technologies for space situational awareness, indicated the future directions of the key technologies, and emphasized the research prospects of multiagent and synergetic constellation technologies for future situational awareness, aiming to provide references for space-based situational awareness to realize space sustainability.
ESA's Swarm dodges collision during climb to escape sun's wrath
Thursday, 14 July 2022 16:45
A swarm? Of bugs?
Not quite—Swarm is ESA's mission to unravel the mysteries of Earth's magnetic field. It's made up of three satellites, A, B and C—affectionately known as Alpha, Bravo and Charlie.
What happened?
A small piece of human-made rubbish circling our planet—known as space debris—was detected hurtling towards Alpha at 16:00 CEST, on 30 June. A potential collision was predicted just eight hours later, shortly after midnight. The risk of impact was high enough that Alpha needed to get out of the way—fast.
There's rubbish in space?
A lot of it. Old satellites, rocket parts and small pieces of debris left over from previous collisions and messy breakups. Each little piece can cause serious damage to a satellite, and larger ones can destroy a satellite and create large amount of new debris.
Was this the first time this has happened?
That day? Maybe. Ever? No way. Each one of the ESA's satellites has to perform on average two evasive maneuvers every year—and that's not including all the alerts they get that don't end up needing evasive action.
Webb begins hunt for the first stars and habitable worlds
Thursday, 14 July 2022 16:29
The first stunning images from the James Webb Space Telescope were revealed this week, but its journey of cosmic discovery has only just begun.
Here is a look at two early projects that will take advantage of the orbiting observatory's powerful instruments.
The first stars and galaxies
One of the great promises of the telescope is its ability to study the earliest phase of cosmic history, shortly after the Big Bang 13.8 billion years ago.
The more distant objects are from us, the longer it takes for their light to reach us, and so to gaze back into the distant universe is to look back in the deep past.
